Abstract

PURPOSE:To obtain the address of an outline in a high speed with a simple constitution, by obtaining a signal of the outline except the inside and the background of a material from input signals and output signals of plural delay circuits. CONSTITUTION:The video signal of an ITV cemera 1 is inputted to a comparator 2 and is converted to a binary signal. This binary signal is inputted to delay circuits 3 and 4 in order. Delay circuits 3 and 4 are operated by clocks from a synchronizing control circuit 7. The input signal of the delay circuit 3 and the output signal of the delay circuit 4 are inputted to a NAND circuit 5, and the output of the NAND circuit 5 and the input signal of the delay circuit 4 are inputted to an AND circuit 6, thus obtaining an outline signal. Horizontal and vertical synchronizing clocks from the synchronizing control circuit 7 are inputted to an address counter 8 of picture elements, and address outputs of picture elements corresponding to the outline signal are taken out.
