Abstract

The present invention provides an auto white balance adjusting device which can appropriately adjust the white balance. A brightest block searching circuit (8) obtains blocks having block representative values, each R,G,B component of which is greater than a respective predetermined threshold value, and selects the brightest one out of the obtained blocks. A brightest block average value calculating circuit (9) obtains an average of the block representative values distributed in the image signal area of a chromaticity near to that of the brightest block. This brightest block average value is thought to be highly influenced by a predominant light source in taking the picture. The white balance can be appropriately adjusted by using this value, irrespective of the kinds of light sources.
