Abstract
PURPOSE: To improve a binary precision by subjecting not data of one line but data of many lines to operation averaging and by using the average value as memory data.
CONSTITUTION: The output signal from a camera is amplified by video amplifier 2, and the signal of amplifier 2 is compared with the output signal of adder 20 by comparator 3, thereby making the signal binary. In this case, operation circuit 16 is provided between A/D converter 12 and one-line memory 13. Circuit 16 operates average values successively for level data inputted for every one line, and the result is inputted to memory 13. Contents of memory 13 are updated and become the newest average value data.
