Abstract

PURPOSE: To obtain the picture having excellent video quality, by preventing halation in case of fluoroscopy and preventing the excessive exposure for the parts other than those covered with the electronegative contrast media in case of pick up.
CONSTITUTION: Video signal is obtained from the television camera controller 10, to pick up the video signal in the field of photo measurement of the photo multiplier 8, the ratio of the part shaded with the electronegative contrast media to the video signal in the field of full photo measurement is detected, to detect the ratio of area of the part actually incident with light to the full photo measurement field in area ratio, and the correction circuit 31 outputting this ratio as the corrective component for the output of the photo multiplier 8 is provided. The correction signal of the correction circuit 31 is given to the automatic exposure controller 12 to correct the detected output of the photo multiplier 8.
