The first lens group receives the first spectroscopic image from the first light exiting surface. The first lens group converts the first spectroscopic image by the first optical magnification and outputs the first optical image from the first image output end. The second lens group is located at the second image end. The second lens group corresponds to the second light exiting surface of the light splitting unit. The second lens set has a second optical power. The second lens group receives the second spectroscopic image from the second light exiting surface.

First, please refer to FIG. 1 to FIG. 3 . FIG. 1 is a block diagram of a photographing device according to an embodiment of the present invention. FIG. 2 is an image of the image capturing device and the first output image obtained by the photographing device of FIG. 1 . And the second output image, FIG. 3 is a block diagram of the image capturing module of FIG. As shown in the figure, the photographing device 1 disclosed in the present invention is, for example, a driving recorder, a sports photographic device, etc., but is not limited thereto. In detail, the photographing device 1 includes an image capturing module 10 , a first sensing unit 20 , a second sensing unit 30 , and a processing unit 40 .

The image capturing module 10 has an image capturing end 11, a first image emitting end 12 and a second image emitting end 13. The image capturing end 11 is for receiving an image entering the image capturing module 10. The first image output end 12 provides a first optical image. In detail, the first optical image has a first optical power. That is to say, after the image enters the image capturing module 10, the image is zoomed at a first optical magnification to form a first optical image. In the present embodiment, the first optical power is substantially 1. That is to say, the first optical image and the image entering the image capturing module 10 are substantially the same size. However, the value of the first optical magnification is not intended to limit the present invention. In other embodiments, the user may adjust the first optical magnification according to his needs.

On the other hand, the second image-emitting end 12 provides a second optical image. The second optical image has a second optical power and the second optical power is greater than the first optical power. Similarly, after the image enters the image capturing module 10, the image is zoomed at a second optical magnification to form a second optical image. In this embodiment, the second optical magnification is greater than 1, for example, 1.45, so that the second optical image is larger than the image entering the image capturing module 10, that is, the image entering the image capturing module 10 is enlarged. Two optical images. In other embodiments of the present invention, the second optical power may also be other values, such as 1.2, 1.6, 2.5, and the like. The user can also adjust the second optical magnification according to his needs.

In the above description, the image capturing module 10 optically adjusts the first optical magnification and the second optical magnification. For example, the user can select an appropriate combination of lenses to adjust the first optical power and the second optical power. For example, the image capturing module 10 can optically process the image entering the image capturing module 10 in a 1:1 manner to obtain a first optical image. On the other hand, the image capturing module 10 can optically enlarge the image entering the image capturing module 10 by 1.45 times (for example, through a convex lens) to obtain a second optical image. In this way, the second optical image has a magnification of 1.45 times compared to the first optical image by optical processing.

The first sensing unit 20 corresponds to the first image emitting end 12, whereby the first sensing unit 20 receives the first optical image. On the other hand, the second sensing unit 30 corresponds to the second image output end 13 , whereby the second sensing unit 30 receives the second optical image.

The processing unit 40 is electrically connected to the first sensing unit 20 and the second sensing unit 30. The processing unit 40 processes the first optical image received by the first sensing unit 20 at a first digital magnification and converts it into a first output image. That is, the processing unit 40 scales the first optical image at a first digital magnification to form a first output image. In this embodiment, the first digital magnification is less than 1, for example, 1/1.4, and thus the first digital image is smaller than the first optical image, that is, the first optical image is reduced to be the first digital image. However, the numerical value of the first digital magnification is not intended to limit the present invention. In other embodiments, other numerical values may be used, such as 1/1.2, 1/1.6, 1/2.5, and the like. Users can also adjust the first digit magnification according to their needs.

On the other hand, the processing unit 40 processes the second optical image received by the second sensing unit 30 by a second digital magnification and converts it into a second output image, and the second digital magnification is greater than the first digital magnification. That is, the processing unit 40 scales the second optical image at a second digital magnification to form a second output image. In this embodiment, the second digital magnification is substantially 1, and thus the second digital image and the second optical image are substantially the same size.

In the above description, the processing unit 40 adjusts the first digital magnification and the second digital magnification by digital means. For example, the processing unit 40 can scale the first optical image by 1.4:1 to obtain a first output image by way of, for example, a Scaler. Thereby, the first optical image of, for example, 2688×1520 can be reduced to a first output image of about 1920×1080. On the other hand, the processing unit 40 can process the second optical image in a 1:1 manner by, for example, Cropping to obtain a second output image. Thereby, a second optical image of, for example, 2688×1520 can be processed to obtain a second output image of 1920×1080.

As described above, after the optical (zoom) and digital (zoom) methods are sequentially processed, the second output image has a magnification of about 2 times (1.45×1.4) compared to the first output image, and the magnification is permeable. The first optical magnification, the second optical magnification, the first digital magnification, and the second digital magnification are selected to be adjusted. In the novel embodiment, since the acquired image is processed by optical and digital means, it has a large magnification.

Referring to FIG. 2 , the imaging device 1 acquires the image A0 via the image capturing module 10 , and the image A0 is processed by the image capturing module 10 and the processing unit 40 to obtain the first output image A1 and the second output image A2 , respectively. As described above, when the first digit magnification is 1/1.4, the second digit magnification is 1, the first digit magnification is 1, and the second digit magnification is 1.45, the second output image A2 is compared with the first output image A1. Zoomed in about 2 times.

The imaging module 10 of this embodiment is further described below. As shown in FIG. 3, the image capturing module 10 includes an image capturing unit 14, a light splitting unit 15, a first lens group 16, and a second lens group 17. The image capturing unit 14 is located at the image capturing end 11. Thereby, the image capturing unit 14 can obtain the image through the image capturing end 11.

The beam splitting unit 15 is, for example but not limited to, a beam splitter. The light splitting unit 15 can split the light entering the spectroscopic unit 15. In detail, the beam splitting unit 15 has a different light incident surface 151 , a first light exit surface 152 and a second light exit surface 153 . In this embodiment, the light incident surface 151 is perpendicular to the first light exit surface 152, the light incident surface 151 is parallel to the second light exit surface 153, and the first light exit surface 152 is perpendicular to the second light exit surface 153. However, the arrangement relationship between the light incident surface 151, the first light exit surface 152, and the second light exit surface 153 is not intended to limit the present invention. In other embodiments, the arrangement between the light-incident surface, the first light-emitting surface, and the second light-emitting surface may be: the light-incident surface is perpendicular to the second light-emitting surface, the light-incident surface is parallel to the first light-emitting surface, and the first light-emitting surface is Vertical second illuminating surface.

The light incident surface 151 corresponds to the image capturing unit 14. The beam splitting unit 15 receives an input image from the light incident surface 151 and outputs a first spectroscopic image from the first light exit surface 152. On the other hand, the input image received by the spectroscopic unit 15 from the light incident surface 151 may also output a second spectroscopic image from the second light exit surface 153. In this way, after the splitting is performed, the spectroscopic unit 15 can simultaneously output the first spectroscopic image and the second spectroscopic image.

The first lens group 16 is located at the first image exit end 12. In detail, the first lens group 16 may include at least one optical lens (for example, a convex lens, a concave lens, etc.), and the user may select the type and arrangement of the lenses according to their needs. The first lens group 16 corresponds to the first light-emitting surface 152 of the light splitting unit 15 . In this way, the first lens group 16 can receive the first spectroscopic image output by the beam splitting unit 15 from the first light emitting surface 152. Then, the first lens group 16 converts the first spectroscopic image to the first optical image and outputs the first optical image from the first image output end 12 . As described above, when the first optical magnification is 1, the first optical image output by the first lens group 16 has the same size as the image entering the image capturing unit 14.

The second lens group 17 is located at the second image-emitting end 13. In detail, the second lens group 17 can include at least one optical lens (for example, a convex lens, a concave lens, etc.), and the user can select the type and arrangement of the lenses according to their needs. The second lens group 17 corresponds to the second light exit surface 153 of the light splitting unit. Thereby, the second lens group 17 can receive the second spectroscopic image output by the beam splitting unit 15 from the second light exiting surface 153. Then, the second lens group 17 converts the second spectroscopic image by the second optical magnification and outputs the second optical image from the second image output end 13. The second optical magnification of the second lens group 17 is greater than the first optical power of the first lens group 16. That is, when the second optical magnification is 1.45, the second optical image output by the second lens group 17 is actually enlarged by 1.45 times compared with the image entering the image capturing unit 14.
