Flicker correction method and device, and imaging device

A flicker correction device in which a flicker is corrected by subtracting a flicker correction signal from an image signal, the device comprising:

• a correction error detecting means for removing noise from the flicker-corrected image signal by passing the latter through a low-pass filter and generating a correction error signal from the noise-removed, flicker-corrected image signal and the image signal not yet flicker-corrected;
• and
• a flicker correcting means for removing the image signal not yet flicker-corrected by passing the latter through a low-pass filter and generating a flicker correction signal from the noise-removed image signal and correction error signal.

An image pickup device including a flicker correction device in which a flicker is corrected by subtracting a flicker correction signal from an image signal captured by an image sensing means, the flicker correction device comprising:

• a correction error detecting means for removing noise from the flicker-corrected image signal by passing the latter through a low-pass filter and generating a correction error signal from the noise-removed, flicker-corrected image signal and the image signal not yet flicker-corrected;
• and
• a flicker correcting means for removing the image signal not yet flicker-corrected by passing the latter through a low-pass filter and generating a flicker correction signal from the noise-removed image signal and correction error signal.
