Abstract

Abstract A color image processing apparatus wherein different color filters (45) are provided in an image pickup device (20) corresponding to plural groups of small pixels, each group of which is one unit of color pixels, and color image signals are obtained from the common position of the small pixel groups by suitably interpolating color image signals obtained from the small pixel groups.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 52 words
A color image processing apparatus comprising an image pickup system (20) having different color filters (45) corresponding to plural groups of small pixels, each group of which is one unit of color pixels, and means for correcting an output signal from each small pixel according to the position of the small pixel.
Claim 2
Dependent Claim 52 words
A color image processing apparatus comprising an image pickup system (20) having different color filters (45) corresponding to plural groups of small pixels, each group of which is one unit of color pixels, and means for correcting an output signal from each small pixel according to the position of the small pixel.
Claim 3
Dependent Claim 22 words
A color image processing apparatus according to Claim 1, wherein said image pickup system (20) uses a contact type image sensor (43).
Claim 4
Dependent Claim 20 words
A color image processing apparatus according to Claim 1, wherein said color filters (45) are red, green and blue filters.
