Abstract

PURPOSE: To eliminate the needless level fluctuation of pickup signals dependent upon difference in exposure timing by lighting a light source by a power source which holds always the luminance of an object constant.
CONSTITUTION: Light source 1 is lit by power source 2 which is so constituted that light source 1 can project a uniform light quantity in respect to time, and object 3 is illuminated. Then, shutter 5 of ITV camera 4 is operated to focus the image of object 3 on pickup face 8 of pickup tube 7 through pickup lens 6. This obtained pickup signal is outputted to, for example, pattern inspection unit 9. Then, it is recommended that power source 2 is constituted by a DC power source or a high- frequency power source having a period sufficiently shorter than the shutter opening time.
