发明名称 APPARATUS AND METHOD FOR CORRECTING IMAGE PICKUP SIGNAL, AND VIDEO CAMERA
摘要 An average signal level of image pickup signals generated by a solid-state image pickup device of an image pickup section (112) is detected by an average signal level detection circuit (116). Based on average signal level (APL) data representing the APL thus detected by the circuit (116), a system control microcomputer (117) refers to an APL-to-flare correction level table showing a correction level defined by an average signal level-to-correction level function in which a correction level for a plurality of average signal levels previously stored in a memory (118) is preset to an arbitrary value, and the microcomputer (117) reads flare correction data corresponding to the APL data from the memory (118). Then, a flare correction signal is generated by D/A-converting the flare correction data by a D/A LPF circuit (119), and the flare correction signal is added to the image pickup signals generated by the solid-state image pickup device by adders (114R, 114G, 114B).
