In step S101, after the lens captures an image, the color value of each pixel in the image is acquired.

The user presses the camera function key provided by the mobile terminal to take a picture, the camera captures the current image data, and the image sensor processes and outputs the image data, thereby obtaining the color value of each pixel in the image captured by the lens.

Preferably, the color value is in a red-green-blue RGB format, including a red component pixel value, a green component pixel value and a blue component pixel value. When the image data output by the image sensor is in the yuv format, the image data in the yuv format is converted into RGB format data. For example, when the yuv format is converted to RGB format, it is assumed that the yuv format of the image data is expressed as (Y, U, V), and the corresponding RGB format is expressed as (R, G, B), and the conversion formula is:

R=Y+1.4075*(V-128)

G=Y-0.3455*(U-128)-0.7169*(V-128)

B=Y+1.779*(U-128)

If the user sets the target object detection function, after obtaining the image data in RGB format output by the image sensor, the local feature detection is performed on the image data, and the current image data is judged by the preset classifier whether it satisfies the corresponding features to detect preset target objects. Wherein, the detection of the preset target object is performed through the HAAR feature algorithm, which is a classifier of corresponding local features obtained by using local feature data samples obtained under various scene conditions for training. Preferably, the target objects include but are not limited to red lips, red scarves, four-cornered pinwheels, eyeballs and the like.

In step S102, when it is detected that the image contains a preset target object, set the color value of the pixel corresponding to the preset target object to the first color value and set the color values of the remaining pixels on the image is the second color value.

In the embodiment of the present invention, the remaining pixels on the image are the remaining pixels on the image except the pixels corresponding to the preset target object.

Wherein, the first color value may be the RGB color value input by the user through the pop-up prompt box when starting the target object detection function, or may be the color value of the pixel corresponding to the target object output by the image sensor.

Exemplarily, when the first color value is the RGB color value set by the user, the second color value is the grayscale value of the pixel, and if it is detected that the image contains a preset target object, then the preset The color value of the pixel corresponding to the target object is the RGB color value set by the user (that is, the color set by the user), and the remaining pixels on the image except the pixel corresponding to the target object are grayscaled processing, so that the remaining part of the image except the pixel corresponding to the target object appears black and white, so that the image obtained after processing achieves the effect of monochrome photography, that is, only the set color color is displayed on the target object , while other parts are displayed in black and white, greatly enhancing the artistic sense of the captured image.

Preferably, the second color value may also be a corresponding color value processed by a filter, such as a black and white filter, nostalgic filter, light green filter, tone filter, and print filter.

In the embodiment of the present invention, after the lens captures the image, the color value of each pixel in the image is acquired; when the preset target object is detected in the image, the color value of the pixel corresponding to the preset target object is set be the first color value and set the color value of the rest of the pixels on the image to the second color value; wherein, the rest of the pixels on the image are the pixels on the image except for the pixels corresponding to the preset target object The rest of the pixels, so as to achieve monochrome photography, the acquired photos are highlighted in the preset color on the preset target object, while the rest of the preset target object is displayed in other colors, which greatly improves the user's shooting sense of experience.
