Abstract
PURPOSE: To prevent the reduction of apparent picture quality by detecting a signal level, adding a distance correction from the photometer field, and adding to a normal detecting signal from the photometer field as a correction.
CONSTITUTION: A correction circuit 31 which obtains a picture signal from the TV camera controller, divedes the region other than the photometer field of the photomultiplier tube 8, extracts the picture signal, compares the extracted picture signal with the level at which a halation occurs to extract the picture signal the level of which is higher than the halation level, and integrates and adds the extracted signal to output is provided. Output from the correction circuit 31 is input to the automatic exposure controller 12 to correct the sensitivity.
