Abstract
An image pickup apparatus is provided with: an objective optical system; an image pickup device; a contrast AF section adjusting a focus so that a peak value of a contrast evaluation value of an image is taken; an amount-of-motion detecting section detecting, from a plurality of time-series images, amounts of motion of the subject; and a control section controlling the contrast AF section so as to calculate another contrast evaluation value in a region where a region to be excluded where an amount of motion is equal to or larger than a threshold is excluded from a calculation target region, and the contrast AF section corrects the other contrast evaluation value based on an area of the calculation target region and an area of the region where the region to be excluded is excluded from the calculation target region.
