Abstract

Abstract An image processing system for recording or reproducing image information includes: a reader for photo-electrically reading image information from a photo disc; a movable storage medium such as a photo sensitive drum in which image information has been stored; a recorder such as a printer for recording on a recording medium the image information read out from the reader; and a signal transmitter such as a line buffer memory for transmitting the image information read out by the reader to the recorder in response to a synchronization signal from the recorder, in which this synchronization signal and a synchronization signal of the reader are formed on the basis of the same internal reference clock of the recorder. With this system, the successive image information can be stably and certainly recorded or reproduced on a nearly real-time basis without using a page memory.
