Abstract
There is provided an image pickup apparatus that, even if image data has insufficient depth difference between an object and a background, accurately discriminates a region including an object and a region including a background. The image pickup apparatus includes a generation unit configured to generate image data, and a discrimination unit configured, based on first image data generated by the generation unit, when an in-focus position is at a first focal position at which an object is in-focus state or a second focal position on a short distance side of the first focal position, and second image data generated by the generation unit, when an in-focus position is at a third focal position on a far distance side of a focal position at which a background is in-focus state, to discriminate a first region including the object and a second region including the background.
