Abstract: A color image reading device for reading a document image imaged on a line image sensor, wherein the line image sensor is a CCD including a first pixel line consisting of pixels having a first reading spectral characteristic and a second pixel line consisting of pixels having the second and third reading spectral characteristics arranged alternately; a two-layer dichroic mirror is provided on the CCD, said optical element for generating double images of an optical image corresponding to said first reading spectral characteristic and another optical image corresponding to the total of said first and second reading spectral characteristics; and the separation distance between the double images generated and imaged on the CCD by the dichroic mirror is approximately equal to the distance between said two lines of pixels on the CCD.

Abstract: Input/output areas of device elements are provided at opposite ends of the original substrate, and two function areas are provided between the opposite input/output areas. The original substrate composing a large-size device is cut along lines in such a way that the input/output areas and the function areas are separated from one another. As a result, those portions of the original substrate where no function areas are to be formed are reduced, thereby contributing to effective utilization of the surface of the substrate for increasing the number of sensor substrates that can be yielded from it. The process is improved in the shape and layout of the substrates for electronic devices to be obtained by cutting the large-area device formed on the substrate and it hence is capable of yielding a greater number of electronic device elements from the large-area device.

Abstract: There is provided an improvement on a solid-state type color image sensor having a color filter arrangement matching the line sequential color difference signal method. A color filter selected from magenta, yellow and cyan for covering the entire area of each picture cell and a color filter of a different color are superposed one upon the other. The color filters covering predetermined ratios of the areas of associated picture cells are preferably formed collectively in a stripe shape.
