Abstract

PURPOSE:To obtain a picture without any overlapping when the picture is reproduced, by detecting the number of overlapped picture elements among sensors and controlling the address counter of a picture data storing memory. CONSTITUTION:The detection mark 15 is read through the sensor 3 and supplied to the memory 10. The storade data are read successively by an address counter 20, and only the data of the address where the mark 15 exists are counted 23-25. The result of counting are added 33 together, and the data of the X port is sent to the latch circuit 39 through the data selector 35. Then the mark 15 is read out by the sensors 3 and 3' to be supplied to the selectors 10 and 12, and the number of picture elements are counted 23-25, 26-28 for the mark 15 to be added 33 together. The data of the Y port is sent to the latch circuit 40 through the selector 35. A subtraction 43 is given to both latch outputs to obtain the number of picture elements that is read in overlap, and the corresponding signal is produced. Then the counters 20 and 30 are controlled to give a control to the reading and writing of the overlapped data.
