By implementing the embodiment, the shooting mode can be prevented from being started on the terminal by an illegal user, so that the terminal can be effectively prevented from being operated by the illegal user.
In the embodiment of the invention, because the external environments have differences, the illumination intensities received by different areas in the image collected by the terminal may be different, so that the distribution conditions of the light brightness values in the areas are different. The imaging area can be divided into a plurality of sub-image areas according to the distribution condition of the light brightness value of the image displayed by the imaging area, so that the light brightness value of each sub-image area can be further acquired. In addition, the division of the imaging area into the sub-image areas may also be performed by default by the terminal system, for example, the imaging area is divided into four symmetrical sub-image areas.
And S102, judging whether the brightness value of each sub-image area is between a preset minimum brightness value and a preset maximum brightness value.
In the embodiment of the present invention, for each sub-image region, the luminance value of the sub-image region may be compared with a preset luminance value. The preset brightness value can be a brightness value required by normal exposure of a camera of the terminal, and can be a value range, the upper limit of a critical value of the range is a preset maximum brightness value, the lower limit of the critical value is a preset minimum brightness value, and at the moment, the preset maximum brightness value is not equal to the preset minimum brightness value; or a specific value, in which case the preset minimum luminance value is equal to the preset maximum luminance value.

In the embodiment of the invention, the terminal is integrated with a flash lamp module which comprises at least two flash lamps, wherein one sub-image area can correspond to one or more flash lamps in the flash lamp module, and the corresponding flash lamp or flash lamps of each sub-image area can be preset.
In the embodiment of the invention, when the luminance value of the sub-image area is greater than the preset maximum luminance value, the luminance value of the sub-image area is sufficient, and the flash lamp is not required to be used for light supplement, so that the flash lamp corresponding to the sub-image area can be controlled to be turned off.
In the embodiment of the present invention, when the luminance value of the sub-image region is between the preset minimum luminance value and the preset maximum luminance value, the flash lamp corresponding to the sub-image region may also be controlled to be turned off.
And S104, if the brightness value of the sub-image area is smaller than a preset minimum brightness value, adjusting the brightness value of the flash lamp corresponding to the sub-image area to a target brightness value, wherein the target brightness value is a difference value between a standard exposure value and the brightness value of the sub-image area, and the standard exposure value is located between the preset minimum brightness value and a preset maximum brightness value.
In the embodiment of the invention, when the luminance value of the sub-image area is smaller than the preset minimum luminance value, the luminance value of the sub-image area cannot meet the luminance value required by normal exposure of the camera, and at the moment, if a flash lamp is not used for light supplement, the light of the picture displayed in the sub-image area is weak, and the picture is not clear, so that the picture quality is influenced. When the flash lamp corresponding to the sub-image region is used for light supplement, the luminance value of the flash lamp corresponding to the sub-image region needs to be calculated according to the luminance value of the sub-image region and the luminance value required by normal exposure of the camera, so that the risk of insufficient or excessive light supplement of the flash lamp can be reduced, and at the moment, the luminance value of the flash lamp is the luminance value actually output by the flash lamp.
In the embodiment of the present invention, the luminance value of the flash lamp corresponding to the sub-image region is adjusted to a target luminance value, and the target luminance value is obtained by calculating a difference between the luminance value of the sub-image region and a standard exposure value required for normal exposure of the camera, where the standard exposure value may be a preset minimum luminance value, a preset maximum luminance value, an intermediate value between the preset minimum luminance value and the preset maximum luminance value, or any value between the preset minimum luminance value and the preset maximum luminance value. The standard exposure value can be the default of the terminal system or can be set by the user.
For example, assuming that the range of the luminance value required for the normal exposure of the camera of the terminal is 800L x to 1200L x, that is, the preset minimum luminance value is 800L x, the preset maximum luminance value is 1200L x, and the standard exposure value is 1000L x, the luminance value of each sub-image region may be compared with the preset minimum luminance value and the preset maximum luminance value to determine whether the luminance value of the sub-image region is between 800L x to 1200L x, when the luminance value of a sub-image region is determined to be greater than the preset maximum luminance value, the flash corresponding to the sub-image region may be controlled to be turned off, when the luminance value of a sub-image region is determined to be less than the preset minimum luminance value, the absolute difference between the luminance value of the sub-image region (set to be 700L x) and the standard exposure value 1000L x is calculated, and the luminance value of the flash corresponding to the sub-image region is adjusted to the absolute difference, that is 300L x, and when the luminance value of a sub-image region is determined to be between the preset minimum luminance value and the preset maximum luminance value, the corresponding sub-image region may also be controlled to be.

By implementing the method described in fig. 1, the brightness value of the flash lamp corresponding to each sub-image region can be adjusted by comparing the brightness value of each sub-image region included in the image displayed in the imaging region of the terminal with the preset brightness value during shooting, so that the shooting effect during shooting can be improved, the quality of the shot picture can be improved, and the shooting experience of a user can be effectively improved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another flash lamp control method according to an embodiment of the present invention. As shown in fig. 2, the flash control method may include the steps of:
s201, acquiring the light brightness value of each sub-image area included in the image displayed in the imaging area of the terminal.
As an alternative implementation, before step S201 is executed to acquire the light brightness values of the sub-image regions included in the image displayed in the imaging region of the terminal, the flash control method described in fig. 2 may further include the following steps:
21) acquiring the light brightness value distribution information of an image displayed in an imaging area of a terminal;
22) and dividing the image into sub-image areas according to the light brightness value distribution information of the image.
In this embodiment, due to the difference in illuminance of external scenes, some scenes are under strong illumination and some scenes are under weak illumination, so that the luminance values of different areas of an image acquired by the camera may be different. Therefore, the image may be divided into several sub-image regions according to the light intensity value distribution information of the image.
It can be understood that the terminal system divides the image into sub-image regions by default without acquiring the light intensity value distribution information of the image to perform image partition.
In the embodiment of the invention, after the image is divided into a plurality of sub-image areas, the light brightness value of each sub-image area can be acquired.

And S203, if the brightness value of the sub-image area is greater than a preset maximum brightness value, or if the brightness value of the sub-image area is between the preset minimum brightness value and the preset maximum brightness value, controlling the flash lamp corresponding to the sub-image area to be turned off.
S204, if the brightness value of the sub-image area is smaller than a preset minimum brightness value, the brightness value of the flash lamp corresponding to the sub-image area is adjusted to a target brightness value, the target brightness value is a difference value between a standard exposure value and the brightness value of the sub-image area, and the standard exposure value is located between the preset minimum brightness value and a preset maximum brightness value.
In the embodiment of the present invention, before adjusting the luminance value of the flash lamp corresponding to the sub-image region to the target luminance value, the target luminance value needs to be calculated, and the calculation process is as follows: and calculating a difference value between the standard exposure value and the brightness value of the sub-image area, and determining the difference value as a target brightness value, wherein the standard exposure value is between a preset minimum brightness value and a preset maximum brightness value.
As an alternative implementation manner, after the step S202 is executed to determine that the light brightness value of the sub-image region is smaller than the preset minimum light brightness value, and before the step S204 is executed to adjust the light brightness value of the flash corresponding to the sub-image region to the target brightness value, the flash control method described in fig. 2 may further include the following steps:
23) acquiring an included angle between a straight line from a center point of a preview image corresponding to the subimage area to a center point of a camera and a straight line from the center point of the preview image corresponding to the subimage area to a center point of a flash lamp corresponding to the subimage area;
24) and judging whether the included angle is smaller than a preset included angle, if not, adjusting the position of the flash lamp corresponding to the subimage area until the included angle is smaller than the preset included angle, wherein the optimal angle for supplementing light to the subimage area by the flash lamp corresponding to the subimage area is obtained when the included angle is smaller than the preset included angle.
In this embodiment, the flash included in the flash module of the terminal is rotatable, and the position of the flash can be adjusted to fill light into the image at the optimal position.
It can be understood that, before the brightness value of the flash lamp corresponding to the sub-image region is adjusted, the position of the flash lamp corresponding to the sub-image region may be adjusted, so that the flash lamp corresponding to the sub-image region fills light into the sub-image region at the optimal position; the position of the flash lamp corresponding to the sub-image region may also be adjusted after the light brightness value of the flash lamp corresponding to the sub-image region is adjusted, which is not limited in the embodiment of the present invention.
And S205, acquiring the color parameter value of the sub-image area.

In the embodiment of the present invention, the color parameter value of the sub-image region may be an RGB value of the sub-image region, and the color of the flash lamp corresponding to the sub-image region is adjusted to match the RGB value according to the RGB value. If the RGB values are 255, 0, indicating that the color of the sub-image region is red, the color of the flash corresponding to the sub-image region may be adjusted to be red; when the RGB values are 0, 0, and 255, it indicates that the color of the sub-image region is blue, and the color of the flash corresponding to the sub-image region may be adjusted to be blue. By implementing the embodiment, the color of the flash lamp corresponding to the sub-image region can be adjusted according to the color parameter value of the sub-image region, so that the flash lamp can supplement light for the image and also supplement color, and the shot picture is brighter in color and more attractive in appearance.
As an optional implementation manner, for each sub-image region whose luminance value is smaller than the preset minimum luminance value, after adjusting the parameter value of the flash lamp corresponding to the sub-image region to match the parameter value of the sub-image region, the terminal may further output a prompt message to prompt the user that the terminal is currently in the best shooting state. The parameter value of the flash lamp comprises any one or combination of several of the brightness value of the flash lamp, the position of the flash lamp and the color of the flash lamp.
As an alternative embodiment, the flash control method described in fig. 2 may further include the following steps:
25) receiving a shooting instruction input by a user;
26) and responding to the shooting instruction, controlling the terminal to shoot the target object under the condition that the parameter value of the flash lamp is in the adjusted parameter value, and acquiring the shot image.
The shooting instruction can be triggered by a user clicking a certain target key on the terminal, or can be triggered by a user clicking any position of an imaging area of the terminal.
By implementing the method described in fig. 2, during the shooting process, the brightness value of the flash lamp corresponding to each sub-image area can be adjusted by comparing the magnitude relationship between the brightness value of each sub-image area included in the image displayed in the imaging area of the terminal and the preset brightness value; the position of the flash lamp corresponding to each sub-image area can be adjusted, so that the flash lamp corresponding to each sub-image area is in the optimal light supplement position; and adjusting the color of the flash lamp corresponding to each sub-image area to complement the area, so that the shooting effect during shooting can be improved, the quality of shot photos is improved, and the shooting experience of a user is effectively improved.
