Step 401, displaying the user interface of the camera application.

Optionally, the camera application program refers to an application program with a camera function. The camera application program may not only have a camera function, but may also have other functions, such as an instant messaging function, an electronic transaction function, and a web page browsing function.

When the camera application is running in the foreground, the terminal displays the user interface of the camera application.

Optionally, the user interface of the camera application program includes images collected by the camera application program through the camera, camera options, and the like. Of course, the user interface of the camera application program may also include other information, which will not be listed here in this embodiment.

Referring to the user interface 501 of the camera application program shown in FIG. 5 , the user interface 501 includes an image 502 captured by the camera and a camera option 503 .

Step 402, receiving a touch operation on the edge touch area of the terminal.

Optionally, the terminal includes four edge areas, which are: an upper edge area, a lower edge area, a left edge area, and a right edge area. There is at least one edge area with a touch function in the terminal, and in this embodiment, the edge area with a touch function is an edge touch area.

Optionally, a touch sensor is disposed in the edge touch area, and the touch sensor is used to detect whether there is a touch operation (or a touch signal) in real time or periodically. When the touch sensor detects that there is a touch operation, it sends a touch event corresponding to the touch operation to the processor in the terminal, and at this time, the processor in the terminal can sense the touch operation.

Optionally, a thermal sensor is provided in the edge touch area, and the thermal sensor is used to detect whether there is a heat source approaching in real time or periodically. When the touch sensor detects that a heat source is approaching, a corresponding proximity event is sent to the processor in the terminal, and at this time, the processor in the terminal determines that there is a touch operation according to the proximity event.

Optionally, a pressure sensor is provided in the edge touch area, and the pressure sensor is used to detect whether there is a pressing operation in real time or periodically. When the touch sensor detects that there is a pressing operation, it sends a corresponding pressing event to the processor in the terminal, and at this time, the processor in the terminal determines that there is a touch operation according to the pressing event.

Step 403, adjusting shooting parameters of the camera application program according to the touch operation.

Wherein, the shooting parameter is used to adjust the effect of the image captured by the camera application program.

Optionally, in this embodiment, the shooting parameter is one of focal length, sensitivity and white balance.

Among them, the focal length (also referred to as focal length) refers to the distance from the lens center of the camera to the focal point where light gathers. Sensitivity is used to measure the sensitivity of imaging devices to light. White balance is an index used to measure the accuracy of white produced by mixing the three primary colors of red, green and blue in the image displayed on the curved screen.

In one example, the touch operation is a sliding operation on the edge touch area. At this time, the terminal adjusts the shooting parameters of the camera application according to the touch operation, including: determining the adjustment direction for adjusting the shooting parameters according to the sliding direction of the touch operation on the edge touch area, and the adjustment direction includes zooming in (or increasing, increasing etc.) shooting parameters and shrinking (or reducing, lowering, etc.) shooting parameters; determining the adjustment scale for adjusting the shooting parameters according to the sliding distance of the touch operation on the edge touch area; adjusting the shooting parameters according to the adjustment direction and the adjustment scale.

Wherein, the sliding operation refers to a touch operation in which the touch duration exceeds the first duration and the sliding distance changes within the touch duration. Schematically, the first duration is 500ms or 1s, etc., and this embodiment does not limit the value of the first duration.

Wherein, the adjustment scale refers to the numerical value of the shooting parameter that is enlarged or reduced.

Schematically, the sliding distance of the touch operation is positively correlated with the adjustment scale, that is, the larger the sliding distance of the touch operation, the larger the adjustment scale; the smaller the sliding distance of the touch operation, the smaller the adjustment scale.

Of course, in actual implementation, there may also be a negative correlation between the sliding distance of the touch operation and the adjustment scale.

Schematically, when the edge touch area is located in the left side area and/or right side area of the terminal, if the sliding direction of the touch operation is upward, the adjustment direction is to zoom in on the shooting parameter; if the sliding direction of the touch operation is is down, the adjustment direction is to reduce the shooting parameters.

Of course, in actual implementation, it can also be realized that if the sliding direction of the touch operation is downward, the adjustment direction is to enlarge the shooting parameter; if the sliding direction of the touch operation is upward, the adjustment direction is to zoom out the shooting parameter.

Schematically, when the edge touch area is located on the upper side area and/or the lower side area of the terminal, if the sliding direction of the touch operation is to the right, the adjustment direction is to zoom in on the shooting parameters; if the sliding direction of the touch operation is If the direction is to the left, then the adjustment direction is to zoom out the shooting parameters.

Of course, in actual implementation, it can also be realized that if the sliding direction of the touch operation is to the left, the adjustment direction is to enlarge the shooting parameter; if the sliding direction of the touch operation is to the right, the adjustment direction is to zoom out the shooting parameter.

Referring to FIG. 6 , assuming that the shooting parameter is the focal length, the terminal receives a touch operation 600 acting on the edge touch area. The touch position of the touch operation 600 is located in the left edge touch area. The touch operation 600 If the sliding direction is upward, the terminal zooms in on the focal length according to the sliding distance of the touch operation 600 (indicated by a bold box in the figure).

In another example, the touch operation is a long press operation on the edge touch area. At this time, the terminal adjusts the shooting parameters of the camera application according to the touch operation, including: collecting pressure information of the touch operation on the edge touch area through the pressure sensor; and adjusting the shooting parameters to the shooting parameters indicated by the pressure information.

Wherein, the long press operation refers to a touch operation in which the touch duration exceeds the second duration and the sliding distance is constant within the touch duration. Schematically, the second duration is 500 ms or 1 s, etc., and the second duration may be equal to or different from the first duration, and this embodiment does not limit the value of the second duration.

In this implementation manner, a pressure sensor is disposed in the edge touch area, and the pressure sensor is used to collect pressure information of the touch operation when the touch sensor collects the touch operation.

Optionally, the pressure sensor is only disposed at a position corresponding to the edge touch area, so that the internal structure of the terminal can be simplified.

Optionally, the terminal stores the correspondence between the pressure information and the shooting parameters. After the terminal collects the pressure information of the touch operation through the pressure sensor, it searches for the shooting parameters corresponding to the pressure information of the touch operation from the correspondence.

To sum up, the shooting parameter adjustment method provided in this embodiment adjusts the shooting parameters according to the touch operation received by the edge touch area; it can solve the problem that the shooting parameters of the camera application cannot be adjusted when the user operates the terminal with one hand ; Since the user can adjust the shooting parameters by performing a touch operation on the edge touch area with one hand, the convenience of adjusting the shooting parameters is improved.

Optionally, when the mobile terminal includes at least two edge areas, if the touch sensor corresponding to each edge touch area is turned on, the terminal consumes more power. In this embodiment, before step 402, the corresponding holding mode of the terminal is also determined, and the touch function of the edge touch area corresponding to the holding mode among at least two edge touch areas is activated.

Wherein, the touch direction may be determined according to the shape of the touch area corresponding to the touch operation, and the shape of the touch area is determined according to the coordinates of the touch operation.

Schematically, when the touch direction is inclined to the left, the holding mode is right-hand holding; when the touching direction is inclined to the right, the holding mode is left-hand holding.

The second way: when the terminal receives a touch operation acting on the central touch area, it determines the holding mode according to the fingerprint information of the touch operation.

At this time, a fingerprint sensor is provided at a position corresponding to the central touch area, and the fingerprint sensor is used to collect fingerprint information of the touch operation.

Schematically, when the fingerprint information matches the fingerprint template of the right-hand fingerprint, it is determined that the holding method is right-hand holding; when the fingerprint information matches the fingerprint template of the left-hand fingerprint, it is determined that the holding method is left-hand holding.

The third method: the terminal first turns on the touch sensor of the corresponding edge touch area held by the right hand, and detects whether the edge touch area receives a touch operation. If no touch operation is received, it determines that the holding mode is the left hand At this time, turn off the touch sensor of the corresponding edge touch area held by the right hand, and turn on the touch sensor of the corresponding edge touch area held by the left hand; The state of the touch sensor in the edge touch area corresponding to the right hand grip remains unchanged.

Optionally, based on the same principle, the terminal may first turn on the touch sensor of the corresponding edge touch area held by the left hand to determine the holding manner.

Certainly, the terminal may also determine the holding manner in other manners, which are not listed here in this embodiment.

Optionally, the edge touch area corresponding to the holding mode includes the following scenarios:

Scenario 1: The display mode of the terminal is a portrait mode, and the terminal includes a left edge touch area on the left side and a right edge touch area on the right side. At this time, when the grip is held by the right hand, the edge touch area corresponding to the right hand is the right edge touch area; when the grip is left-handed, the edge touch area corresponding to the left hand is the left Edge touch area.

The second scenario: the display mode of the terminal is an inverted portrait mode, and the terminal includes a left edge touch area on the left side and a right edge touch area on the right side. At this time, when the grip is held by the right hand, the edge touch area corresponding to the right hand is the left edge touch area; when the grip is the left hand, the edge touch area corresponding to the left hand is the right Edge touch area.

The third scenario: the display mode of the terminal is a landscape mode, and the curved screen of the terminal includes an upper edge touch area located on the upper side and a lower edge touch area located on the lower side. At this time, when the grip is held by the right hand, the edge touch area corresponding to the right hand is the lower edge touch area; when the grip is the left hand, the edge touch area corresponding to the left hand is the upper edge Edge touch area.

Scenario 4: The display mode of the terminal is the inverted landscape mode, and the curved screen of the terminal includes an upper edge touch area located on the upper side and a lower edge touch area located on the lower side. At this time, when the grip is held by the right hand, the edge touch area corresponding to the right hand is the upper edge touch area; when the left hand is held, the edge touch area corresponding to the left hand is the lower edge. Edge touch area.

It should be added that the edge touch areas corresponding to the above-mentioned gripping modes are only schematic, and other gripping modes and edge touch areas can also be set in actual implementation. List them one by one.

To sum up, in this embodiment, the touch function of which touch operation area is enabled is determined according to the grip mode, which not only ensures that the terminal can adjust shooting parameters according to the touch operation, but also saves battery power of the terminal.
