Summary: | The invention discloses an image-data processing apparatus and an image pickup apparatus. The image-data processing apparatus includes an operation unit; a correcting unit multiplying image data generated by an image pickup device by a correction gain; a totalizing unit sequentially calculating a total pixel level for every frame from the image data; a history holding unit holding the total pixel levels of a certain number; an in-phase averaging unit detecting the total pixel levels in phase with a flicker phase corresponding to the image data that is being supplied to the correcting unit from the held total pixel levels to calculate a first average of the detected total pixel levels; an average calculating unit calculating a second average of the held total pixel levels; and a correction gain calculating unit calculating the correction gain by dividing the first average by the second average to set the correction gain in the correcting unit. |
