Abstract

PURPOSE:To shorten the max. delay time up to the start of reading by reading 1 frame of picture information from the initial input of a horizontal synchronous signal after a reading start signal has been inputted. CONSTITUTION:A reading start signal is inputted at the time of a point t0. At the time of point t1 when a horizontal synchronous signal SH is initially inputted after the time t0, picture information obtained by A/D conversion is started to be read out and the horizontal synchronous signal SH is started to be counted up. The picture information is read from the left end of the 4th scanning line. When the reading of the picture information is ended at the time of point t2 (time TV passes from the time of point t1) when the succeeding horizontal synchronous signal SH is inputted after the counting value of the horizontal synchronous signal SH has reached the horizontal scanning times (n) for 1 frame, just 1 frame of the picture information up to the right end of the 3rd scanning line is read out. Thus, the max. delay time up to the start of reading can be shortened up to one horizontal scanning time.
