Abstract

PURPOSE:To print out a picture without remarkable density difference, by gradually changing the output of both the image sensing arrays in the linking sections which make duplicate read in. CONSTITUTION:A mixing ratio sharing circuit 4 gradually decreases one output A from a given voltage ''1'' every one pulse of an input clock signal, and a voltage of another output B is gradually increased from 0. In the linking sections W, the mixing ratio between the video element signal component read out from the 1st solidstate image sensing array 5 and the video information component read out from the 2nd solidstate image sensing array 6 is changed from 1:0-0:1 gradually.
