Abstract

PURPOSE:To use the titled device by adding the operating section of a memory address at memory input and output, and eliminating the limit of size of picture of input/output of a picture memory and connecting an input and output. CONSTITUTION:In a primary sensor 5, a picture data is read out according to a scanning address signal 10 of a scanning address counter 6 in which the address is incremented with a clock generator 7. The signal 10 is compared with a memory input shart address Xs11 and a memory input stop address Xe12 respectively at comparators 8 and 9, and the comparison result >=13 and the comparison result <=14 are outputted. An output signal is a writen enable signal 22 to a picture memory 20. The write address to the picture memory 20 is incremented for the memory address counter 19 in synchronizing with a clock 16 of the clock generator 7. In this case, the period XL of a memory write enable signal 22 is incremented.
