发明名称 White balance correcting device
摘要 A white balance correcting device for correcting white balance by using video signals is arranged to be capable of accurately obtaining white balance even in a case where a picture includes only a small white part therein. The white balance correcting device is arranged to divide a picture into a plurality of blocks, to obtain a mean value of signals by averaging signals of each divided block as representing the block and a peak value of luminance from a signal having the highest luminance among others in each divided block also as representing the block, and to use, for white balance control, either the mean value or the peak value according to the state of the object of shooting.
