Abstract

PURPOSE:To smooth a joint of plural sensors, and to read an original of a large picture with high resolution, by temporarily storing picture data from each sensor, in a buffer memory, and elimnating one overlapped picture data from an adjacent sensor, when reading out said data. CONSTITUTION:Picture data D1-D3 from plural each image sensor are provided to buffer memories 11, 12, and when one memory 11 or 12 is in the writing mode, the data D1-D3 of 1 scanning line portion are written, and the other memory 12 or 11 is set to the readout mode. Said respective writing and readout are exectued by controlling by an FF13, and an output of the buffers 11, 12 is selected by a multiplexer 14. Also, multiplexers 18, 20 are controlled by a writing address counter 16 and a readout address counter 19. In this state, when the data of the memory 11 or 12 is read out, it is read out by eliminating overlapped picture data from an adjacent sensor, and an original of a large picture is read with high resolution.
