Abstract

PURPOSE:To realize the shading correcting circuit simple in the constitution, easy for adjustment and low in the cost, by performing the shading correction through the storage of video signal for one line's share. CONSTITUTION:The video signal for one line's share obtained by scanning other part of the objective 1 is picked up, the switch 3 is selected to solid lines, and after it is converted into digital signal, it is stored in the one line memory 6. Further, the image of the objective 1 is picked up, the output video signal is fed to the comparator 9 after the switch 3 is selected to broken lines. Since the video signal for one line's share stored in the one line memory 6 is repetitively fed, the video signal in binary level corrected for shading is obtained at the output terminal 14.
