Dual-type solid state color image pickup apparatus and digital camera

摘要

A dual-type solid state color image pickup apparatus has: a color separation prism which separates incident light from an object into first and second colors, and a third color of the three primary colors; a first solid state imaging device which receives incident light of the first and second colors separated by the color separation prism; and a second solid state imaging device which receives incident light of the third color separated by the color separation prism. Each of light receiving portions in the first solid state imaging device is configured by: a first-color detecting high-concentration impurity layer which detects an image signal corresponding to the amount of incident light of the first color; and a second-color detecting high-concentration impurity layer which is formed at a depth different from that of the impurity layer, and which detects an image signal corresponding to the amount of incident light of the second color.
