Patent ID: 8040392

Claim:
A flicker correction circuit comprising: a flicker correction signal sending out circuit section that sends out a flicker correction signal corresponding to the flicker component contained in a video signal of each of specific periods, the video signal being formed as a succession of specific periods and containing a flicker component, in response to a correction error signal for each of the specific periods; an arithmetic processing circuit section that executes an arithmetic process on the flicker correction signal sent out from the flicker correction signal sending out circuit section and the video signal of each of the specific periods to form a corrected video signal of the specific period corrected for the flicker component; and a correction error detecting circuit section that detects the correction error on the flicker component from the corrected video signal of the specific period immediately preceding each of the specific periods and the corrected video signal of the each of the specific periods, acquires the correction error signal of each of the specific periods as a signal corresponding to the detected correction error, supplies the correction error signal to the flicker correction signal sending out circuit section, and acquires the flicker correction signal as a signal for reducing the correction error according to the correction error signal.
