摘要： 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.

摘要： A distance measurement method for calculating distance information from a first image and a second image that are image-captured with different image-capturing parameters. A setting step sets a first local region located in the first image including a distance calculation target pixel, and a second local region located in the second image corresponding to the first local region. An extraction step extracts a plurality of shift regions, which are regions of which a shift amount from the second local region is within a predetermined range. A correlation value is calculated between the first local region and each of the plurality of shift regions. A decision step determines a correlation value used for calculating distance information, based on the plurality of correlation values calculated in the first calculation step. The distance information on the distance calculation target pixel is calculated, based on the correlation value determined in the decision step.
