detailed description

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present application, and cannot be construed as limiting the present application.

In the related art, portable electronic devices such as mobile phones are equipped with cameras, and the imaging principles of the cameras are all based on the convex lens principle. Due to the limitations of the convex lens imaging principle itself, the resulting image center has the best effect, and its effect gradually deteriorates from the image center to the surroundings.

Referring to FIG. 1, the electronic device 1000 according to the embodiment of the present application includes a casing 200 and a camera assembly 100. The camera assembly 100 is exposed through the casing 200.

Exemplarily, the electronic device 1000 may be any one of various types of computer system equipment that is mobile or portable and performs wireless communication (only one form is exemplarily shown in FIG. 1 ). Specifically, the electronic device 1000 may be a mobile phone or a smart phone (for example, an iPhone based on TM, an Android-based phone), a portable game device (for example, Nintendo DS, TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), laptop Computers, PDAs, portable Internet devices, music players and data storage devices, other handheld devices and such as watches, earphones, pendants, headphones, etc. The electronic device 100 can also be other wearable devices (eg, Head-mounted devices (HMD) such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices or smart watches).

The camera assembly 100 includes a first telephoto camera 20, a wide-angle camera 30, and a second telephoto camera 40. The number of the first telephoto camera 20 is plural. For example, the number of the first telephoto camera 20 is 2, 3, 4, etc. In this embodiment, the number of first telephoto cameras is 4 as an example for description. The number of the wide-angle camera 30 and the second telephoto camera 40 is one.

It can be understood that the angle of view of the wide-angle camera 30 is greater than that of the first telephoto camera 20 and the second telephoto camera 30. For example, the wide-angle camera 30 has a viewing angle range of 80-110 degrees, while the first telephoto camera 20 and the second telephoto camera 30 have a viewing angle range of 10-40 degrees.

Therefore, the field of view area of the wide-angle camera 30 is large, and the field of view areas of the first telephoto camera 20 and the second telephoto camera 30 are small. Therefore, the first telephoto camera 20 and the second telephoto camera 30 have better advantages for shooting the local position of the scene.

In this embodiment, the plurality of first telephoto cameras 20, the wide-angle camera 30, and the second telephoto cameras 40 are arranged in a matrix, as shown in FIG. Of course, in other embodiments, the plurality of first telephoto cameras 20, wide-angle cameras 30, and second telephoto cameras 40 may be arranged in any shape.

The first telephoto camera 20 and the second telephoto camera 40 may both be vertical cameras, or may be periscope cameras, and the wide-angle camera 30 may be a vertical camera. The vertical lens module refers to that the optical axis of the lens module is a straight line, or that incident light is transmitted to the photosensitive device of the lens module along the direction of the linear optical axis. In this embodiment, the first telephoto camera 20 is a periscope camera as an example for further description.

Referring to FIGS. 2-4, in this embodiment, the first telephoto camera 20 includes a housing 21, a reflective element 22, a mount 23, a first lens assembly 24, a moving element 25, a first image sensor 26, and a driving mechanism 27.

The reflective element 22, the mounting base 23, the first lens assembly 24, and the moving element 25 are all disposed in the housing 21. The reflective element 22 is disposed on the mounting base 23, and the first lens assembly 24 is fixed on the moving element 25. The moving element 25 is provided on the first image sensor 26 side. Further, the moving element 25 is located between the reflective element 22 and the first image sensor 26.

The driving mechanism 27 connects the moving element 25 and the housing 21. After the incident light enters the housing 21, it passes through the reflective element 22, and then passes through the first lens assembly 24 to reach the first image sensor 26, so that the first image sensor 26 obtains an external image. The driving mechanism 27 is used to drive the moving element 25 to move along the optical axis of the first lens assembly 24.

The housing 21 has a substantially square shape. The housing 21 has a light inlet 211 from which incident light enters the first telephoto camera 20. That is to say, the reflective element 22 is used to redirect the incident light incident from the light entrance 211 and pass through the first lens assembly 24 to the first image sensor 26 so that the first image sensor 26 senses the first telephoto camera 20 incident light outside.

It can be understood that the light inlet 211 is exposed through the through hole 11 so that external light passes through the through hole 11 and enters the first telephoto camera 20 from the light inlet 211.

Specifically, referring to FIG. 3, the housing 21 includes a top wall 213 and a side wall 214. The side wall 214 extends from the side 2131 of the top wall 213. The top wall 213 includes two opposite sides 2131, the number of the side walls 214 is two, and each side wall 214 extends from a corresponding side 2131, or the side walls 214 are respectively connected to the top wall 213 On both sides. The light inlet 211 is formed on the top wall 213.

The reflective element 22 is a prism or a plane mirror. For more details, please refer to FIGS. 4 and 7. The reflective element 22 has a light incident surface 222, a backlight surface 224, a reflective surface 226 and a light exit surface 228. The light incident surface 222 approaches and faces the light entrance 211. The backlight surface 224 is away from the light entrance 211 and opposite to the light entrance surface 222. The reflective surface 226 is connected to the light incident surface 222 and the backlight surface 224. The light exit surface 228 is connected to the light entrance surface 222 and the backlight surface 224. The light exit surface 228 faces the first image sensor 26. The reflective surface 226 is inclined relative to the light incident surface 222. The light emitting surface 228 is opposite to the light reflecting surface 226.

Specifically, during the light conversion process, the light passes through the light inlet 211 and enters the light reflecting element 22 from the light incident surface 222, then reflects through the light reflecting surface 226, and finally reflects the light reflecting element 22 from the light emitting surface 228 to complete the light conversion During the process, the backlight surface 224 and the mounting base 23 are fixedly arranged, so that the reflective element 22 remains stable.

Therefore, referring to FIG. 8, the reflective element 22 of the embodiment of the present application cuts off the corner away from the light entrance relative to the reflective element in the related art, which not only does not affect the reflected light effect of the reflective element 22, but also reduces the reflective element The overall thickness of 22.

Please refer to FIG. 4. In some embodiments, the angle α of the reflective surface 226 relative to the light incident surface 222 is inclined at 45 degrees. In this way, the incident light is better reflected and converted, and has a better light conversion effect.

The reflective element 22 may be made of glass, plastic, or other materials with relatively good light transmittance. In one embodiment, a reflective material such as silver may be coated on one surface of the reflective element 22 to reflect incident light.

The mounting base 23 is used to mount the reflective element 22, or the mounting base 23 is a carrier of the reflective element 22, and the reflective element 22 is fixed on the mounting base 23. This allows the position of the reflective element 22 to be determined, which is advantageous for the reflective element 22 to reflect or refract incident light. The reflective element 22 may be fixed on the mounting base 23 by viscose to achieve a fixed connection with the mounting base 23.

Specifically, in this embodiment, the mounting base 23 is provided with a limiting structure 232, and the limiting structure 232 is connected to the reflective element 22 to limit the position of the reflective element 22 on the mounting base 23.

In this way, the limiting structure 232 limits the position of the reflective element 22 on the mounting base 23, so that the reflective element 22 will not be displaced in the event of an impact, which is beneficial to the normal use of the first telephoto camera 20.

It can be understood that in one example, the reflective element 22 is fixed on the mounting base 23 by means of bonding. If the limiting structure 232 is omitted, then, when the first telephoto camera 20 is impacted, if the reflective element 2222 and the mounting base 23 The adhesive force between them is insufficient, and the reflective element 22 is easily detached from the mounting base 23.

In this embodiment, the mounting base 23 is formed with a mounting groove 233, the reflective element 22 is disposed in the mounting groove 233, and the limiting structure 232 is disposed at the edge of the mounting groove 233 and abuts against the reflective element 22.

In this way, the mounting groove 233 can make the reflective element 22 easily mounted on the mounting base 23. The limiting structure 232 is disposed at the edge of the mounting groove 233 and abuts the edge of the reflective element 22, which not only restricts the position of the reflective element 22, but also does not prevent the reflective element 22 from emitting incident light to the first image sensor 26.

Further, the limiting structure 232 includes a protrusion 234 protruding from the edge of the mounting groove 233, and the protrusion 234 abuts the edge of the light emitting surface 228. Since the reflective element 22 is mounted on the mounting base 23 through the reflective surface 226, the light exit surface 228 is disposed opposite to the reflective surface 226. Therefore, the light reflecting element 22 is more likely to generate a position toward the side of the light exit surface 228 when subjected to an impact. In this embodiment, the limiting structure 232 abuts against the edge of the light-emitting surface 228 can not only prevent the reflective element 22 from shifting to the light-emitting surface 228 side, but also ensure that the light exits the light-emitting surface 228 normally.

Of course, in other embodiments, the limiting structure 232 may include other structures as long as the position of the reflective element 22 can be limited. For example, the limiting structure 232 is formed with a clamping slot, and the reflective element 22 forms a limiting column, and the limiting column is engaged in the clamping slot to limit the position of the reflective element 22.

In some embodiments, the protrusion 234 is strip-shaped and extends along the edge of the light exit surface 228. In this way, the contact area between the protrusion 234 and the edge of the light exit surface 228 is large, so that the reflective element 22 can be more firmly located on the mounting base 23.

Of course, in other embodiments, the protrusion 234 may also have a block-like structure.

Please refer to FIG. 3 again. In one example, the mounting base 23 can be movably disposed in the housing 21, and the mounting base 23 can rotate relative to the housing 21 to adjust the direction in which the reflective element 22 turns the incident light.

The mounting base 23 can drive the reflective element 22 to rotate toward the opposite direction of the shaking of the first telephoto camera 20, thereby compensating the incident deviation of the incident light of the light inlet 211, and achieving the effect of optical anti-shake.

The first lens assembly 24 is accommodated in the moving element 25. Further, the first lens assembly 24 is disposed between the reflective element 22 and the first image sensor 26. The first lens assembly 24 is used to image incident light on the first image sensor 26. This allows the first image sensor 26 to obtain an image with better quality.

When the first lens assembly 24 moves integrally along its optical axis, it can image on the first image sensor 26, so that the first telephoto camera 20 can focus. The first lens assembly 24 includes a plurality of lenses 241. When at least one lens 241 moves, the overall focal length of the first lens assembly 24 changes, thereby achieving the zoom function of the first telephoto camera 20. More, driven by the driving mechanism 27 The moving element 25 moves in the housing 21 to achieve zooming.

In the example of FIG. 4, in some embodiments, the moving element 25 is cylindrical, and the plurality of lenses 241 in the first lens assembly 24 are fixed in the moving element 25 along the axial interval of the moving element 25. As shown in the example of FIG. 6, the moving element 25 includes two clips 252 that sandwich the lens 241 between the two clips 252.

It can be understood that because the moving element 25 is used to fix a plurality of lenses 241, the length of the required moving element 25 is large, and the moving element 25 can be cylindrical, square, etc., having a shape of a certain cavity, so moving The element 25 is arranged in a tube, so that a plurality of lenses 241 can be better arranged, and the lens 241 can be better protected in the cavity, so that the lens 241 is less likely to shake.

In addition, in the example of FIG. 6, the moving element 25 sandwiches the plurality of lenses 241 between the two clips 252, which not only has a certain stability, but also reduces the weight of the moving element 25, and can reduce the driving of the driving mechanism 27. The power required by the moving element 25, and the design difficulty of the moving element 25 is also relatively low, and the lens 241 is also easier to set on the moving element 25.

Of course, the moving element 25 is not limited to the cylindrical shape and the two clips 252 mentioned above. In other embodiments, the moving element 25 may include three or four clips 252 to form a more stable structure. , Or a simpler structure such as a clip 252; or a rectangular body, a circular body, etc. having a cavity to accommodate various regular or irregular shapes of the lens 241. On the premise of ensuring the normal imaging and operation of the imaging module 10, specific selection is sufficient.

The first image sensor 26 may use a complementary metal oxide semiconductor (CMOS) complementary photosensitive element or a charge-coupled device (CCD) charge-coupled device (CCD) photosensitive element.

In some embodiments, the driving mechanism 27 is an electromagnetic driving mechanism, a piezoelectric driving mechanism, or a memory alloy driving mechanism.

Specifically, the electromagnetic drive mechanism includes a magnetic field and a conductor. If the magnetic field moves relative to the conductor, an induced current is generated in the conductor. The induced current causes the conductor to be subjected to an ampere force, which causes the conductor to move. The conductor here is electromagnetic. The part of the drive mechanism that drives the moving element 25; the piezoelectric drive mechanism is based on the inverse piezoelectric effect of the piezoelectric ceramic material: if a voltage is applied to the piezoelectric material, mechanical stress is generated, that is, electrical energy and mechanical energy are converted, through Controlling its mechanical deformation to produce rotation or linear motion has the advantages of simple structure and low speed.

The drive of the memory alloy drive mechanism is based on the characteristics of the shape memory alloy: the shape memory alloy is a special alloy. Once it remembers any shape, even if it deforms, it can be restored to a certain temperature when heated The shape before deformation, in order to achieve the purpose of driving, has the characteristics of rapid displacement and free direction.

Please refer to FIG. 4 again. Further, the first telephoto camera 20 further includes a driving device 28 for driving the mounting base 23 with the reflective element 22 to rotate about the rotation axis 29. The driving device 28 is used to drive the mounting base 23 to move in the axial direction of the rotation axis 29. The rotation axis 29 is perpendicular to the optical axis of the light inlet 211 and the photosensitive direction of the first image sensor 26, so that the first telephoto camera 20 realizes optical anti-shake in the optical axis of the light inlet 211 and the axis of the rotation axis 29 .

In this way, because the volume of the reflective element 22 is smaller than that of the lens barrel, the driving device 28 drives the mounting base 23 to move in two directions, which not only can realize the optical anti-shake effect of the first telephoto camera 20 in two directions, but also The volume of the first telephoto camera 20 is made smaller.

Please refer to FIGS. 3 to 4. For convenience of description, the width direction of the first telephoto camera 20 is defined as the X direction, the height direction is defined as the Y direction, and the length direction is defined as the Z direction. Thus, the optical axis of the light inlet 211 is in the Y direction, the light receiving direction of the first image sensor 26 is in the Z direction, and the axial direction of the rotation axis 29 is in the X direction.

The driving device 28 drives the mounting base 23 to rotate, so that the reflective element 22 rotates around the X direction, so that the first telephoto camera 20 realizes the Y-direction optical image stabilization effect. In addition, the driving device 28 drives the mounting base 23 to move in the axial direction of the rotation axis 29, so that the first telephoto camera 20 realizes the X-direction optical image stabilization effect. In addition, the first lens assembly 24 may be along the Z direction to enable the first lens assembly 24 to focus on the first image sensor 26.

Specifically, when the reflective element 22 rotates in the X direction, the light reflected by the reflective element 22 moves in the Y direction, so that the first image sensor 26 forms a different image in the Y direction to achieve the anti-shake effect in the Y direction. When the reflective element 22 moves in the X direction, the light reflected by the reflective element 22 moves in the X direction, so that the first image sensor 26 forms a different image in the X direction to achieve the anti-shake effect in the X direction.

In some embodiments, the driving device 28 is formed with an arc-shaped guide rail 281, and the drive device 28 is used to drive the mounting base 23 to rotate along the arc-shaped guide rail 281 about the central axis 282 of the arc-shaped guide rail 281 and the axis along the central axis 282 Moving toward, the central axis 2282 coincides with the rotation axis 29.

It can be understood that the driving device 28 is used to drive the mounting base 23 to rotate along the arc guide rail 281 about the central axis 282 of the arc guide rail 281 and move axially along the central axis 282.

In this way, since the driving device 28 uses the curved guide rail 281 to drive the mounting base 23 with the reflective element 22 to rotate together, the friction between the driving device 28 and the mounting base 23 is small, which is conducive to the smooth rotation of the mounting base 23 , The optical image stabilization effect of the first telephoto camera 20 is improved.

Specifically, please refer to FIG. 9. In the related art, the mounting base (not shown) is rotatably connected to the rotating shaft 23 a, and the mounting base rotates around the rotating shaft 23 a to drive the reflective element 22 a to rotate together. Assume that the friction force is f1, the radius of the rotating shaft 23a is R1, the thrust force is F1, and the radius of rotation is A. Then the friction torque to thrust torque ratio K1 is K1=f1R1/F1A. Since the reflective element 22a only needs to rotate slightly when performing anti-shake, F1 cannot be too large, because the excessive rotation of F1 will cause the rotation of the reflective element 22a to be too large to achieve the anti-shake function; and the imaging module itself needs to be light and short to cause reflective The size of the element 22a cannot be too large, so the space for the enlargement of A is also limited, so that the influence of friction cannot be further eliminated.

Please refer to FIG. 10, and in this application, the mounting base 23 rotates along an arc-shaped guide rail 281, and the arc-shaped guide rail 281 may be formed by arranging a plurality of rolling bodies 2811. The radius of the rolling element 2811 is R2. At this time, the ratio K2 of the friction torque and the turning torque is K2=f2R2/F2B. In the case where f1 is not significantly changed compared to f2, R1 is compared to R2, and F1 is compared to F2, due to the adoption of The orbital swinging method rotates, and the corresponding turning radius becomes B, and B can not be limited by the size of the reflective element 22, and can even be several times more than A. Therefore, in this case, the influence of friction on the rotation of the reflective element 22 can be greatly reduced (the size of K2 is reduced), thereby improving the rotational accuracy of the reflective element 22, and making the optical anti-shake effect of the first telephoto camera 20 more effective good.

Referring to FIG. 4, in some embodiments, the mounting base 23 includes an arc-shaped surface 231 that is concentrically disposed with the arc-shaped guide rail 281 and cooperates with the arc-shaped guide rail 281. In other words, the center of the curved surface 231 coincides with the center of the curved guide 281. This makes the mounting base 23 and the driving device 28 more compact.

In some embodiments, the central axis 282 is located outside the first telephoto camera 20. In this way, the radius R2 of the arc-shaped guide rail 281 is large, which can reduce the adverse effect of friction on the rotation of the mounting base 23.

In some embodiments, the driving device 28 electromagnetically drives the mounting base 23 to rotate. In one example, the driving device 28 is provided with a coil, and an electromagnetic sheet is fixed on the mounting base 23. After the coil is energized, the coil can generate a magnetic field to drive the movement of the electromagnetic sheet, thereby driving the mounting base 23 and the reflective element to rotate together.

Of course, in other embodiments, the driving device 28 may drive the mounting base 23 in a piezoelectric driving manner or a memory alloy driving manner. For the piezoelectric driving method and the memory alloy driving method, please refer to the above description, which will not be repeated here.

Please refer to FIGS. 2-5 again. The first telephoto camera 20 further includes a chip circuit board 201 and a driving chip 202. The chip circuit board 201 is fixed on the side of the driving mechanism 27, and the driving chip 202 is fixed on the chip circuit board 201 and the driving mechanism. On the opposite side of 27, the driving chip 202 is electrically connected to the driving mechanism 27 through the chip circuit board 201.

In this way, the driving chip 202 is fixed to the side of the driving mechanism 27 through the chip circuit board 201, and is electrically connected to the driving mechanism 27 through the chip circuit board 201, which makes the structure between the driving chip 202 and the driving mechanism 27 more compact, which is beneficial to The volume of the first telephoto camera 20 is reduced.

Specifically, the driving chip 202 is used to control the driving mechanism 27 to drive the moving element 25 to move along the optical axis of the first lens assembly 24, so that the first lens assembly 24 is focused and imaged on the first image sensor 26. The driving chip 202 is used to control the driving device 28 according to the feedback data of the gyroscope 120 to drive the mounting base 23 with the reflective element 22 to rotate around the rotation axis 29.

Please refer to FIGS. 12 and 13. The imaging method according to the embodiment of the present application may be used in the above electronic device 1000. Specifically, the imaging method includes the following steps:

S10. Acquire an image collected by the wide-angle camera 30 as a reference image P1. The reference image P1 includes an intermediate region P11 and an edge region P12;

S20. Acquire images respectively collected by the plurality of first telephoto cameras 20 as the first preprocessed image P2, where the field of view area of the plurality of first preprocessed image P2 includes the field of view area of the edge area P12;

S30. Acquire an image collected by the second telephoto camera 40 as the second preprocessed image P3, where the field of view area of the second preprocessed image P3 includes the field of view area of the middle area P11;

In S40, the reference image P1, the first preprocessed image P2 and the second preprocessed image P3 are fused to obtain the target image P4.

Referring to FIG. 14, the present application discloses an imaging device 300. The imaging device 300 includes a first acquisition module 310, a second acquisition module 320, a third acquisition module 330, and a fusion module 340. Therefore, step S10 in the imaging method may be executed by the first acquisition module 310, step S20 may be executed by the second acquisition module 320, step S30 may be executed by the third acquisition module 330, and step S40 may be executed by the fusion module 340.

In other words, the first acquisition module 310 is used to acquire the image collected by the wide-angle camera 30 as the reference image P1. The second acquisition module 320 is used to acquire images respectively acquired by the plurality of first telephoto cameras 20 as the first preprocessed image P2. The third acquisition module 330 is used to acquire the image collected by the second telephoto camera 40 as the second preprocessed image P3. The fusion module 340 is used to fuse the reference image P1, the first preprocessed image P2 and the second preprocessed image P3 to obtain the target image P4.

15, in some embodiments, the electronic device 1000 further includes a processor 10, which is used to obtain an image collected by the wide-angle camera 30 as a reference image P1; and used to obtain multiple first telephoto cameras 20 The separately collected images are taken as the first pre-processed image P2; and the images used to obtain the second telephoto camera 40 are taken as the second pre-processed image P3; and are used to fuse the reference image P1, the first pre-processed image P2 and the second Preprocess the image P3 to obtain the target image P4.

In the imaging method, imaging device 300, and electronic device 1000 of the embodiment of the present application, the first pre-processed image P2 captured by the first telephoto camera 20 can compensate for the sharpness of the edge area P12 of the reference image P1 captured by the wide-angle camera 30, and , The second pre-processed image P3 captured by the second telephoto camera 40 can further compensate the sharpness of the intermediate region P11 of the reference image P1 captured by the wide-angle camera 30, therefore, the sharpness of each region of the target image P4 obtained by fusion High, improves the quality of the target image P4.

Specifically, in step S10, the middle area P11 of the reference image P1 refers to the area located at the center of the reference image P1 (as shown in FIG. 13 within the dotted frame), and the edge area P12 refers to the reference image P1 except the middle area The area outside P11 (the part outside the dotted frame in FIG. 13). In one example, the reference image P1 has a center point, and the middle area P11 is an area distributed around the center point. The area of the middle area P11 is 1/5-2/3 of the total area of the reference image P1. For example, the area of the intermediate area P11 is 1/5, 1/4, 1/3, or 2/3 of the total area of the reference image P1.

Since the reference image P1 is captured by the wide-angle camera 30, the image in the middle area P11 has higher definition and better quality, and the image quality in the edge area P12 is worse than the image quality in the middle area P11.

In step S20, the field of view area refers to the range of the field of view acquired by the camera corresponding to the image. For example, the size of a scene is 4*6m, and the size of the target object in the scene is 2*3m. If the wide-angle camera 30 can capture the image of the scene and the first telephoto camera can only capture the image of the target object, then the field of view area of the scene image includes the field of view area of the target object image .

Thus, the image content after the stitching of the plurality of first pre-processed images P2 includes the image content of the edge area P12 of the reference image P1. That is to say, the image after the stitching of the plurality of first pre-processed images P2 has the same shape as the image of the edge area P12.

For example, when the reference image P1 includes a human body image, the edge region P12 of the reference image P1 may include a human head image. At this time, the image after the stitching of the plurality of first pre-processed images P2 includes a human head image, and may further include a human chest image.

In this embodiment, the number of first telephoto cameras 20 is four, so the number of first pre-processed images P2 is also four. In one example, the field of view areas of the four first pre-processed images P2 are each a quarter of the field of view area of the reference image P1, that is, the field of view areas of the four first pre-processed images P2 are respectively The upper left area, the upper right area, the lower left area, and the lower right area of the field of view of the reference image P1. At this time, the stitched image content of the four first pre-processed images P2 has not only the image content of the edge area P12 of the reference image P1 but also the image content of the middle area P11 of the reference image P1.

In step S20, a plurality of first telephoto cameras 20 may be set to face different shooting directions, so as to obtain first pre-processed images P2 in different fields of view.

In step S30, in this embodiment, the field of view area of the second preprocessed image P3 includes the field of view area of the intermediate area P11 means that the field of view area of the second preprocessed image P3 may cover the field of view of the intermediate area P11 The area may overlap the field of view area of the intermediate area P11. Thus, the image content of the second preprocessed image P3 includes the image content of the middle area P11 of the reference image P1. That is to say, the image after splicing the second preprocessed image P3 has the same image as the image in the middle area P11.

In step S30, the field of view of the image captured by the second telephoto camera 40 may be set by setting the shooting direction of the second telephoto camera 40.

In step S40, the obtained target image P4 has a high-definition quality. In an example, when the number of the first pre-processed image P2 is four, the images of the upper left, upper right, lower left, lower right, and middle areas of the target image P4 are acquired by different telephoto cameras, respectively, therefore, The image quality of these five areas is better, so that the quality of the target image P4 is better.

It should be noted that the image content of the target image P4 includes the image content of the background image P1, the first preprocessed image P2, and the second preprocessed image P3.

Further, preferably, the reference image P1, the first preprocessed image P2 and the second preprocessed image P3 are collected at the same time. In other words, the wide-angle camera 30, the first telephoto camera 20 and the second telephoto camera 40 can be controlled to be exposed at the same time to simultaneously acquire the reference image P1, a plurality of first preprocessed images P2 and second preprocessed images P3.

Similarly, the quality of the image formed after the fusion of the second pre-processed image P3 and the intermediate region P11 of the reference image P1 is better.

In this way, since the plurality of first pre-processed images P2 are all captured by the first telephoto camera 20, the first to-be-processed image P23, which is relatively clear, can be obtained by fusing the plurality of first pre-processed images P2 first. The image quality of the edge region P12 and the middle region P11 of the second to-be-processed image obtained by fusing the image P23 and the reference image P1 is better.
