Abstract
PURPOSE: To enable to reproduce the picture correctly, in which the video element concentration level is uniformly distributed, by normalizing the input video element concentration data and comparing and outputting in with the threshold pattern stored.
CONSTITUTION: The input video element concentration data 1 is normalized through the normalizing unit 2, and the threshold pattern stored in advance in the memory 3 is outputted to the comparator 6 via the address indicator unit 4 in synchronizing with the data transfer clock 5 inputted and it is compared with the data 1 and outputted from the output buffer 7. Thus, without lowering the resolution and ability of reproduction, the picture distributed uniformly and continuously for the video element concentration level can accurately be reproduced.
