Abstract:
Even in case the shutter speed is high, a flicker can be corrected accurately. A flicker correction method in which a flicker is corrected by predicting, from a present input frame image, a flicker component in an image of a next frame and adding a correction value to the next frame image on the basis of the predicted flicker component includes holding a plurality of flicker data, calculating the correction value by combining a plurality of flicker data together at a ratio set correspondingly to a shutter speed and frame rate, and adding the calculated correction value to the input image signal.
