Abstract
An average signal level of imaging signals obtained by a solid-state image pickup device of an image pickup unit is detected by an average signal level detection circuit . Based on APL (average picture level) data specifying the average signal level APL as detected by this average signal level detection circuit , a system control micro-computer refers to a table of an average signal level versus correction level finction specifying the correction level in the plural average signal levels previously stored in a memory to read out flare correction data conforming to the APL data. A D/A-LPF circuit converts the flare correction data by digital/analog (D/A) conversion to generate flare correction data, which are summed by adders R, G and B to imaging signal obtained by said solid-state image pickup device.
