Abstract

PURPOSE:To achieve accurate binary-coding of original signals, by preventing a floating slice level from being followed to synchronizing signals and the like. CONSTITUTION:An image pickup signal A' is clamped at a clamp level 2-4 by a clamp circuit 31 to eliminate a synchronizing signal 2-1. When a floating slice level is formed at an integral network 32 based on this clamped signal, excellent tracking to video information can be achieved since the synchronizing signal 2-1 gives no effect on integration. Further, stable clamp operation can be made to the level change in the pickup signal A', by floating a clamp level 2-4 through the provision of an integral network 34.
