Color image pickup device

Abstract

Abstract PURPOSE: To prevent the color mixture and thus to obtain the chrominance signal featuring a high color regeneration by forming the light shields in the vertical scan direction and between every 2nd unit of the light receiver element via the 2-dimensional CCD pickup element. CONSTITUTION: Color filter 81 formed through repetition of plural units of color filter elements is piled on the 2-dimensional CCD pickup element comprising light receiver elements 68∼71 plus charge transfer parts 61∼64 extending toward the vertical scanning direction. The signal charge caused by the green light coming in through green light transmission filter 82 is stored in element 69 and 70. In the same way, the yellow light is stored in the receiver element adjacent to element 71 after passing through filter 83. The light comming in through the area near the boundary between filter element 82 and 83 of color filter 81 is cut off by shield film 72 formed on channel stopper region 66 and 67 each, thus preventing the mixture of the signal charge between receiver elements 68 and 69 or 70 and 71. As a result, the chrominance signal can be obtained with no mixture of colors. COPYRIGHT: (C)1980,JPO&Japio
