Patent ID: 7656458

Claim:
A color photographing device that has a light-receiving section having a green pixel selectively receiving green light and outputting a green pixel signal corresponding to a light amount received, and a pixel selectively receiving a light with a color different from the green light and outputting an other pixel signal corresponding to an other light amount received, comprising: a colorimetry unit estimating color temperature of a photography light source; a white balance adjusting section adjusting white balance of the signals output from the light-receiving section by multiplying a white balance gain to each of the green pixel signal and the other pixel signal of the signals being output; and an exposure adjusting section configuring a setting so as to increase a white balance gain that is multiplied to the green pixel signal when the estimated color temperature is at a color temperature of when the signal level of the green pixel signal is lower than the signal level of the other pixel signal at the time of photographing achromatic color, the achromatic color being illuminated by the photography light source of the color temperature, and setting an amount of exposure at the light-receiving section to a value lower than a proper exposure amount by an amount corresponding to an increment of the white balance gain multiplied to the green pixel signal.
