IMAGE SENSOR FOR IMPLEMENTING COLOR IMAGE USING COLOR FILTERS OF TWO COLORS

摘要

PURPOSE: An image sensor for implementing a color image using color filters of two colors is provided to simplify processes for arraying the color filters, and improve light sensitivity because a blue color filter is not used. CONSTITUTION: A unit pixel(200) includes a substrate on which a light sense device(22), an insulator film(24) and a color separation film(26) are formed. Only yellow and cyan color filters are arrayed on a location corresponding to the light sense device(22). A color filter is not arrayed on a region where a color filter of another color has to be arrayed. A signal correction process part(250) receives a signal output from the light sense device(22) that corresponds to each of white, yellow and cyan color filters, and thereby generates an RGB signal for red, green and blue colors. The signal correction process part(250) executes addition, subtraction, division and multiplication in order to improve the quality of a color.
