PURPOSE:To always obtain a picture signal of high quality, by measuring the light volume received at the position near a slit through a monitor part for the received light volume and extracting the output of a photodetector on the detecting surface corresponding to the position of the picture element based on the result of the above-mentioned measurement from a picture detecting device in the form of a standardized signal. CONSTITUTION:A generating part 11 for picture element light receiving value stroes the arranging directions X1-XN of the photodetectors and the light volumes Y1-YN received at the photodetectors. Then the part 11 designates a signal Yi based on the output signal given from a monitor part 8 for received light volume in the form of the light volume received by the photodetector corresponding to the arrangement position signal Xi which is delivered from a picture element signal generating part 13. Based on this obtained value, the output of the photodetector at a detecting part 6 corresponding to the position of each picture element can be extracted after the standardization. |
