Abstract:
An image sensor chip comprising:a plurality of light receiving elements for photoelectric conversion, the plurality of light receiving elements having light receiving surfaces serving as a plurality of image reading picture elements, the plurality of image reading picture elements being arranged in a row at a constant pitch on the chip; wherein the number N of the image reading picture elements is defined as N=nÂ·k (other than an integer multiple of 16); wherein n represents the number of image signals processed as a group when the image signals from the light receiving elements are subjected to level correction on a group-by-group basis; wherein k is a minimum integer satisfying 0wherein &ggr; is a resolution defined as the number of image reading picture elements per predetermined unit length; and wherein p is a minimum difference between required reading widths as calculated on the basis of said unit length.
