Abstract:
An image pickup apparatus which is capable of, even when a flash band appears during a zooming operation, properly compensating for the flash band to generate a post-compensation image having no different levels of luminance. A lens unit has a zoom function. Image information generated based on image signals output from an image pickup device, which sequentially starts exposure and sequentially reads out signals for each row of pixels, is held in a memory unit. Based on the image information, the flash band caused by an external flash and extending across a plurality of frames is detected, and frames in which the flash band was detected are corrected to obtain an image having no different levels of luminance. The frames are corrected according to a calculated zoom change ratio of the lens unit when the zoom change ratio does not fall inside a first range determined in advance.

Claim (Index 16):
A control method for an image pickup apparatus having a lens unit that has a zoom function, and an image pickup device that sequentially starts exposure and sequentially reads out signals for each row of pixels, comprising:\n a signal processing step of generating image information based on image signals output from the image pickup device; a storage step of holding, in a memory unit, the image information generated in the signal processing step; a detection step of, based on the image information held in the memory unit, detecting a flash band that is caused by an external flash and extending across a plurality of frames; a correction step of correcting the frames in which the flash band was detected in the detection step to an image having no different levels of luminance; and a determination step of determining a zooming state of the lens unit, wherein in the determination step, if it is determined that a predetermined change in the zooming state occurs, the frames are not corrected in the correction step.
