Abstract
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 line and the next odd or even horizontal line are different from each other so as to provide a 180° phase difference.

Claim 1
Independent Claim
238 words
A solid-state color imaging apparatus comprising: first and second image pickup means each having a plurality of pixels successively arranged vertically and horizontally with a pitch for outputting electric signals in response to incident light thereon, the pixel arrangements of said first and second image pickup means being shifted by 1/2 the pitch from each other in the horizontal direction; separation means for separating green and red, blue lights from a light incident thereon which includes optical information corresponding to an object viewed by said solid-state color imaging apparatus; and first and second filter means disposed on surfaces of said first and second image pickup means, said first filter means having light-transmission portions all of which transmit the green light from said separation means, and said second filter means having 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, said red-light transmission portions and said red-and-blue-light transmission portions of each of said horizontal lines being alternately arranged, and the arranging orders thereof on one odd or even horizontal line and the next odd or even horizontal line being different from each other, the separated green light being introduced through said first filter means into said first image pickup means and the separated red and blue lights being introduced through said second filter means into said second image pickup means.
