Solid-state image pickup element plate

Abstract

Abstract PURPOSE:To obtain a high-quality image signal, by setting random one of the area, the form and the arrangement of the picture element in an image pickup element plate to secure a uniform distriution of the space frequency of a picture element arrangement pattern and to suppress the occurrence of a moire phenomenon at a specific frequency. CONSTITUTION:A solid-state image pickup element plate consists of a red signal extracting photodetector R, a green signal extracting photodetector G and a blue signal extracting photodetector B. The form and the size are set constant with the arrangement pattern set random for each picture element. The area or the form are set random when the arrangement pattern is set constant. Thus the space frequency distribution is set uniform for each picture element pattern, and the occurrence of a moire phenomenon is suppressed at a specific frequency along with suppression of the local peak. Then the deterioration of picture quality such as the occurrence of a false color signal, a reduction of image resolution, etc. can be avoided.
