Picture processing device

Abstract

Abstract PURPOSE:To minimize the processing data and to make small-sized the capacity of the memory means by providing a measuring means to measure the position where the binarization signal is dislocated from white to black or from black to white, and a memory means to store the measured value of the dislocating position. CONSTITUTION:A latch pulse generating circuit 11 detects the position where the binarization signal is dislocated from the white part to the black part and the position where the signal is dislocated from the black part to the white part, and generates the pulse. On the other hand, for a counter 12, a vertical synchronizing signal is inputted, the counting of the clock is started, and a setting pulse generating circuit 13 generates the setting pulse by a horizontal synchronizing signal and resets the counter 12. The contents of the counter 12 is latched by a pulse from the circuit 11 at a latch circuit 14, and transferred to a RAM, etc. Consequently, the number (contents of the counter 12) of the clock generated for each time up to the rise and fall of the binarization signal from the synchronizing signal is transferred and stored to the RAM.
