Abstract
An image pickup apparatus includes an imaging unit that acquires a first image by capturing an object at a first focusing position, and acquires a second image after acquiring the first image, by capturing the object at a second focusing position different from the first. The second image has different blur than the first image. A depth information determination unit determines depth information of the object on the basis of a difference in blur between the first image and the second image. A focusing position setting unit sets a focus movement amount that is a difference between the first focusing position and the second focusing position, in accordance with an F-number of the imaging unit. The second focusing position is set such that an absolute value of the focus movement amount is larger when the F-number is large, as compared to when the F-number is relatively small.
