Abstract
PURPOSE:To define a picture by picking up an out-of-focus image and in-focus image by the same image pickup element in a picture reader and by obtaining an output picture on the basis of the difference between both the pictures. CONSTITUTION:Liquid crystal plate 5 between lens 2 and image pickup element 3 is supplied with an ON-OFF signal from synchronizing circuit 4 to supply image pickup element 3 with an out-of-focus image and in-focus image alternately. An in-focus signal for a single scan is stored in memory 9 by way of amplifier 7 and inputted to differential amplifier 10 together with the out-of-focus image obtd. Through amplifier 8 to obtain a difference picture output. Therefore, since the difference output picture has the high frequency range emphasized in comparision with the original picture, the picture is defined in details and variance in sensitivity between pixcell can be corrected.
