ABSTRACT:
Disclosed is an automatic white balance method for image capturing apparatus. An image capturing apparatus captures a color image first and performs gray point searching in RGB color space or YUV color space. The color correction coefficient sets of red color, green color and blue color components of each gray points are computed respectively, and then the color correction coefficient sets of all the gray points are averaged to generate a color correction average value set. Each pixel of the color image is color-corrected in a color space according to the color correction average value set so as to obtain an optimum white balance effect. The present invention is beneficial for the reduction of design cost, downsizing of storage memory space, decrease of computation quantity and simplification of image-searching process.
