Abstract
In a color CCD camera, a distance between a micro lens and a photodiode is determined dependent on a color light among red, green and blue. Alternative to this structure, a curvature of a micro lens is determined dependent on a color light among red, green and blue. In accordance with this structure, high sensitivity is obtained with improved color balance.
