专利汇可以提供Parallel picture processor专利检索,专利查询,专利分析的服务。并且PURPOSE: To simplify an electric circuit configuration, and to obtain excellent edge detecting ability by setting a unit allowable area for each threshold element at a light receiving element arrangement pattern where the areas are mutually incorporated at every threshold element without overlapping the adjacent threshold element.
CONSTITUTION: A single unit allowable area 13 consists of nine photoelectric converting cells, consists of a pattern combined with a black-coated central area cell PD
0 and eight peripheral area cells PD
1 to PD
8 , which are arranged at the peripheral positions and indicate a half tone pattern, and to void parts, the photoelectric converting cells (peripheral area cells) forming the other unit light allowable areas are allocated. Since the unit light allowable area for each threshold element is formed of the light receiving element arrangement pattern which does not overlap the adjacent threshold element, it can be made to correspond to the threshold element as a single output of a single light receiving element, it is unnecessary to provide a current/voltage converting element at every light receiving element, and since the light receiving element arrangement pattern is mutually incorporated at every adjacent threshold element, the excellent edge detecting ability is exerted.
