Abstract

PURPOSE: To obtain picture information faithful to an original picture even if the photoelectric conversion element on a solid scanning element is defective, by converting a "black-white-black" level to correct picture information only when the "black-white-black" level appears before and after the abnormal bit position of picture information obtained by read scanning of the original.
CONSTITUTION: In the picture information read system where a solid scanning element is used to read and scan an original and the output is taken out by binary coding, binary-coded data at a dark output time obtained from the solid scanning element before read scanning of the original is stored in memory unit RAM previously. When the original is read and scanned actually, binary-coded data at the dark output time is outputted from memory unit RAM synchronously with binary- coded signal S2 outputted from the solid scanning element, and continuous picture signal parts of a "black-white-black" of binary-coded signal S2 of the original are converted to the picture signal of a "black-black-black" level.
