Abstract:
A color balance adjusting device, by which a color balance of a color image, which is obtained by combining at least a first color component signal, a second color component signal, and a third color component signal, is adjusted, said device comprising:a color component adjusting processor that adjusts a chromaticity of each of said first and second color component signals;a control processor that controls said color component adjusting processor in one of a first color balance mode, in which said chromaticity of said first color component signal and said second color component signal are increased while maintaining said chromaticity of said third color component signal, and a second color balance mode, in which said chromaticity of said first color component signal and said second color component signal are decreased while maintaining said chromaticity of said third color component signal;an image indicating processor that indicates a second color image obtained by synthesizing said first and second color component signals, which arc adjusted by said color component adjusting processor, together with said third color component signal, which remains unadjusted;a parameter setting processor that sets a parameter, anda correction coefficient calculating processor that obtains a first correction coefficient corresponding to said first color component signal and a second correction coefficient corresponding to said second color component signal based on said parameter, said control processor controlling said color component adjusting processor in accordance with said first correction coefficient and said second correction coefficient.
