Abstract

PURPOSE:To reduce the effect of noise, by storing the binary coded video signals into plural video signal memories that are successively connected in parallel, and reading simultaneously these contents of storage to allot them with decision by majority. CONSTITUTION:The video signal supplied from a TV camera 1 is sampled by a sampling circuit 2 and then binary coded through a comparator 4. The binary coded video signals are stored successively in video signal memories 11-13 via a shift register 6 by switching a frame change-over circuit 8. Then the contents of storage of memories 11-13 are read simultaneously by a discriminator 14 to be delivered to a TV monitor 20 with decision by majority.
