Abstract

In some embodiments, images for the video conference may be white balanced. White balancing may include dividing at least a subset of an image's pixels into multiple ranges according to their luminance and chrominance values. For example, at least a portion of the pixels in an image may be sorted into different groups (i.e., by incrementing counters respective to each group) according to the luminance and chrominance values of the pixels. If enough pixels are found to be in a particular group, a portion or all of the image may be adjusted by a ratio corresponding to that particular group. For example, blue and red analog gains (corresponding to the selected pixels) may be modified by a corresponding ratio to bring red and blue accumulations closer to green accumulations.
