Abstract

A solid-state color imaging apparatus including first and second CDs for outputting electric signals in response to incident lights thereon and a prism for separating to green and red, blue lights a light incident thereon which includes optical information corresponding to an object viewed by the solid-state color imaging apparatus. In front of the first and second CCDs are provided first and second color filters whereby the separated green light is introduced through the first color filter into the first CCD and the separated red and blue light is introduced through the second color filter into the second CCD. The first color filter has light-transmission portions all of which transmit the green light from the prism, and the second color filter has red-light transmission portions and red-and-blue-light transmission portions which are successively arranged in horizontal and vertical directions so as to form a pattern comprising horizontal lines and vertical lines. The red-light transmission portions and the red-and-blue-light transmission portions of each of the horizontal lines are alternately arranged successively and the arranging orders thereof on one odd or even horizontal lin…
