Referring to fig. 1, fig. 1 is a first structural schematic diagram of a shooting method according to an embodiment of the present disclosure. The shooting method comprises the following steps:
Specifically, a physical key may be preset on the mobile terminal to receive a shooting instruction of the user, or a shooting button is provided in the shooting software, and the shooting instruction is triggered and generated when the user clicks the shooting button.
Wherein, the mobile terminal includes the light source that exposes outside this mobile terminal, for example: the mobile terminal comprises a flashlight, a charging signal indicator lamp and the like, wherein the flashlight, the charging signal indicator lamp and the like can automatically control the light source to emit light when the mobile terminal is in a dark or bright environment so as to irradiate a target object. The mobile terminal can be installed with various applications required by the user, such as applications with entertainment functions (e.g., video applications, audio playing applications, game applications, and reading software), and applications with service functions (e.g., map navigation applications, dining applications, etc.).
And 102, controlling the light source to emit light according to the first brightness and shoot the target object according to the shooting instruction to obtain a target image.
Specifically, after a shooting instruction triggered by user operation is detected, the light source is controlled to emit light according to preset first brightness so as to illuminate a target object, and after the camera is focused, the camera is controlled to shoot the illuminated target object, so that a target image is obtained.
When the scene brightness of the mobile terminal is not too high or too low, the light source does not need to be lightened, so that the ambient light intensity of the current environment of the mobile terminal can be detected after a shooting instruction is received, and if the detected ambient light intensity is less than the preset first ambient light intensity, the current ambient light intensity is relatively weak, and the light source needs to be lightened; or if the detected ambient light intensity is greater than the preset second ambient light intensity, it indicates that the current ambient light intensity is brighter, and the light source may be turned on so as to prevent the shot target object from being overexposed. Therefore, before the controlling the light source to emit light at the first brightness and shoot the target object to obtain the target image, the method may further include:
detecting the ambient light intensity of the current environment where the mobile terminal is located according to the shooting instruction;
and if the ambient light intensity is smaller than a first ambient light intensity or the ambient light intensity is larger than a second ambient light intensity, controlling the light source to emit light according to a first brightness and shooting a target object to obtain a target image, wherein the second ambient light intensity is larger than the first ambient light intensity.
On the contrary, if the detected current ambient light intensity is between the first ambient light intensity and the second ambient light intensity, it indicates that the scene brightness of the current mobile terminal is not too high or too low, and the light source does not need to be turned on. Therefore, before the controlling the light source to emit light at the first brightness and shoot the target object to obtain the target image, the method may further include:
and if the ambient light intensity is greater than the first ambient light intensity and less than the second ambient light intensity, forbidding to start the light source, and shooting the target object to obtain the target image.
And 103, processing the target image to obtain a processed image.
Specifically, when the target object is photographed, the target object is irradiated by the light source with light emitted at a first luminance having a low emission luminance, but the luminance of an image photographed by irradiating the target object with light having a low luminance is insufficient, which may cause a factor affecting the photographing quality such as insufficient luminance of the image. Therefore, it is necessary to process the captured target image so as to simulate the image captured by irradiating the target object with light emitted from the light source at the second luminance higher than the luminance.
The mode of simulating the light source to emit light according to the second brightness and shooting the image obtained by the target object can be to adjust the image parameters of the target image, so that the processed image obtained by simulating the light source to emit light according to the second brightness and shooting the target object is obtained. Thus, step 103 may comprise:
and adjusting the image parameter value in the target image to obtain a processed image.
Specifically, considering that the light source irradiates on the target object when emitting light, the luminance of the area of the target object facing the light source is high, and the luminance of the area spreading from the area to the periphery is low, it may be determined which area of the target image obtained by shooting has an image parameter value larger than the first preset image parameter value, and which area has an image parameter value smaller than the first preset image parameter value, so as to determine the area facing the light source and the area spreading from the area to the periphery when shooting. And when the target image is processed, adjusting image parameters in different areas respectively, so as to simulate an image shot by the light source emitting light according to the second brightness and irradiating the target object. Therefore, the adjusting the image parameter value in the target image to obtain a processed image includes:
determining a first area of the target image with the image parameter value larger than a first preset image parameter value;
determining a second area of the target image, wherein the image parameter value is smaller than a first preset image parameter value;
and adjusting the image parameter value of the first area to be a second preset image parameter value, and adjusting the image parameter value of the second area to be a third preset image parameter value.
Wherein the image parameter values include:
one or more of an image grayscale parameter value, an image lightness parameter value, and an image saturation parameter value.
The shooting method provided by the embodiment of the application comprises the following steps: receiving a shooting instruction; controlling the light source to emit light according to first brightness and shoot a target object according to the shooting instruction to obtain a target image; and processing the target image to obtain a processed image, wherein the processed image is an image obtained by simulating the light source to emit light according to a second brightness and shooting a target object, and the second brightness is greater than the first brightness. The light source emits light with high brightness when shooting is simulated by carrying out post-processing on the target image, so that the problems of light source loss and overlarge power consumption of the mobile terminal are avoided.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a second shooting method according to an embodiment of the present disclosure. The shooting method comprises the following steps:
Specifically, a physical key may be preset on the mobile terminal to receive a shooting instruction of the user, or a shooting button is provided in the shooting software, and the shooting instruction is triggered and generated when the user clicks the shooting button.
Wherein, the mobile terminal includes the light source that exposes outside this mobile terminal, for example: the mobile terminal comprises a flashlight, a charging signal indicator lamp and the like, wherein the flashlight, the charging signal indicator lamp and the like can automatically control the light source to emit light when the mobile terminal is in a dark or bright environment so as to irradiate a target object. The mobile terminal can be installed with various applications required by the user, such as applications with entertainment functions (e.g., video applications, audio playing applications, game applications, and reading software), and applications with service functions (e.g., map navigation applications, dining applications, etc.).
Specifically, after a shooting instruction triggered by user operation is detected, the light source is controlled to emit light according to preset first brightness so as to illuminate a target object, and after the camera is focused, the camera is controlled to shoot the illuminated target object, so that a target image is obtained.
When the scene brightness of the mobile terminal is not too high or too low, the light source does not need to be lightened, so that the ambient light intensity of the current environment of the mobile terminal can be detected after the shooting instruction is received
If the detected ambient light intensity is less than the preset first ambient light intensity, the current ambient light intensity is relatively weak, and the light source needs to be lightened; or if the detected ambient light intensity is greater than the preset second ambient light intensity, it indicates that the current ambient light intensity is brighter, and the light source may be turned on so as to prevent the shot target object from being overexposed.
And 204, if the ambient light intensity is greater than the first ambient light intensity and less than the second ambient light intensity, forbidding turning on the light source, and shooting the target object.
On the contrary, if the detected current ambient light intensity is between the first ambient light intensity and the second ambient light intensity, it indicates that the scene brightness of the current mobile terminal is not too high or too low, and the light source does not need to be turned on.
Specifically, when the target object is photographed, the target object is irradiated by the light source with light emitted at a first luminance having a low emission luminance, but the luminance of an image photographed by irradiating the target object with light having a low luminance is insufficient, which may cause a factor affecting the photographing quality such as insufficient luminance of the image. Therefore, it is necessary to process the captured target image so as to simulate the image captured by irradiating the target object with light emitted from the light source at the second luminance higher than the luminance.
The mode of simulating the light source to emit light according to the second brightness and shooting the image obtained by the target object can be to adjust the image parameters of the target image, so that the processed image obtained by simulating the light source to emit light according to the second brightness and shooting the target object is obtained.
Considering that the light source irradiates on the target object when emitting light, the brightness of the area of the target object opposite to the light source is high, and the brightness of the area spreading to the periphery from the area is low, it can be determined which area of the target image obtained by shooting has the image parameter value larger than the first preset image parameter value, and which area has the image parameter value smaller than the first preset image parameter value, so as to determine the area opposite to the light source and the area spreading to the periphery from the area when shooting.
After the area over which the light source is directed and the area spreading from the area to the periphery are determined in step 205 and this step, image parameters in different areas are adjusted respectively when the target image is processed, so that an image shot by the light source emitting light at a second brightness and illuminating the target object is simulated.
The shooting method provided by the embodiment of the application comprises the following steps: receiving a shooting instruction; controlling the light source to emit light according to first brightness and shoot a target object according to the shooting instruction to obtain a target image; and processing the target image to obtain a processed image, wherein the processed image is an image obtained by simulating the light source to emit light according to a second brightness and shooting a target object, and the second brightness is greater than the first brightness. The light source emits light with high brightness when shooting is simulated by carrying out post-processing on the target image, so that the problems of light source loss and overlarge power consumption of the mobile terminal are avoided.

The mobile terminal can be installed with various applications required by the user, such as applications with entertainment functions (e.g., video applications, audio playing applications, game applications, and reading software), and applications with service functions (e.g., map navigation applications, dining applications, etc.).
And the shooting module 32 is used for controlling the light source to emit light according to the first brightness and shooting the target object according to the shooting instruction to obtain a target image.
