Problems solved by technology

Under these complex and changeable lighting conditions, it is more challenging to make the images captured by the camera, especially the facial images of the user, have better results.
It is very common that the overall color of the user's face will be far from normal, such as turning yellow or blue, which will greatly affect the user's enthusiasm for using the camera

Embodiment 1

[0027] In Embodiment 1, the process of adjusting image color is as follows figure 1 shown, including the following steps:

[0028] Step S101, capturing images of the area in front of the screen;

[0029] Step S102, statistically analyzing the color of the captured image to obtain the color cast value between it and the set target color;

[0030] In this step, each color component of the captured image is counted and compared with each component value of the set target color to obtain the color cast value of each color component.

[0031] For example, in an example of Embodiment 1, the statistical average values ​​of each color component of RGB (Red Green Green, red, green and blue) are respectively (90, 90, 80), and each component value of the set target color is (100 , 100, 80), it can be seen that the average value of the color components obtained by statistics is compared with each component value of the set target color, and the average value of the red and green compone...

Embodiment 2

[0043] Since the present invention is especially applicable to the situation of network video chatting, it is very important to compensate the color cast of the image of the face area. Therefore, in the second embodiment, the process of adjusting the color of the image is as follows: figure 2 shown, including the following steps:

[0044] Step S201, capturing an image of the area in front of the screen;

[0045] Step S202, detecting the captured image, and obtaining the face area therein;

[0046] Step S203, perform statistical analysis on the color of the face area to obtain the color cast value between it and the set target color;

[0047] Since in this embodiment, it is hoped that after the color cast compensation is performed on the imaging area, the color of the face area in the captured image can be close to the color of a normal face, therefore, the setting target color used in this step can be The color of the face obtained by estimating statistical values ​​(that i...

Embodiment 3

[0052] The device for adjusting image color in embodiment three, such as image 3 shown, including:

[0053] A camera module 100, configured to obtain captured images;

[0054] The color analysis module 200 is used to statistically analyze the color of all or part of the captured image obtained by the camera module 100 to obtain a color cast value between it and the set target color;

[0055] The control module 300 is configured to adjust the screen light source according to the color cast value obtained by the color analysis module 200 .

[0056] The device may further include a face detection module, configured to detect the captured image obtained by the camera module 100, obtain a face area therein, and instruct the color analysis unit to perform statistical analysis on the face area.

Abstract

A method for regulating color of image includes shooting image at front region of screen, carrying out statistics and analysis on color of all or partial shot images to obtain color matching value between color of all or partial shot images and color of set object then carrying out color matching compensation on shooting region by regulating screen light source according to color matching value.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a method, device and computer for adjusting image color. Background technique [0002] Existing PC (Personal Computer, personal computer) cameras or cameras built into notebook computers are often used for network video chatting. Generally, the usage environment is: the user is sitting indoors (such as office, home, Internet bar, etc.) in front of the display screen, and the camera shoots at the user. The indoor lighting types can be various, for example, fluorescent lamps, incandescent lamps, or other types of lighting. In addition, the layout of indoor lighting is also different. For example, the lighting may shine on the user from various directions such as the front area, the side front area, the side, and the side rear. Under these complex and changeable lighting conditions, it is more challenging to make the images captured by the camera, especially the facial images ...
