Abstract

PURPOSE: To correct easily and economically shading generated in the horizontal direction and the vertical direction by changing properly the width of the opening slit of a shutter disc.
CONSTITUTION: Reflection light flux 3 from moving object 2 dependent upon illuminating equipment 1 is caused to pass or cut off by opening slit 5, which is provided on the circumference of rotatable shutter disc 4, and is exposed to light as a static picture on pickup face 8 of pickup tube 7 in pickup unit 6. Then, the width of opening slit 5 is defined as a shape changed according to a shading generation part so that the picture obtained by reproducing pickup signals can be prevented from generating shading. For example, when shading which becomes darker towards the lower part of the reproduced picture is generated, opening slit 9a whose width in the lower part for the pickup picture is wider is used to expose the lower part of the pickup picture to light for a time longer than the upper part of the pickup picture, thereby eliminating shading of the reproduced picture.
