Abstract
An image pickup apparatus includes: an image pickup device that outputs pixel signals picked up by a plurality of pixels arranged in a two-dimensional manner for picking up an image of an object; a white spot positional information storage portion that stores positional information of a white-spot pixel that exists in the image pickup device; an image pickup device drive portion; and a white spot correction portion that, based on positional information of the white-spot pixel that is read out from the white spot positional information storage portion, performs correction with respect to the pixel signal of the pixel that is determined to be the white-spot pixel based on a white spot correction value calculated based on seven pixels that surround a pixel that is determined to be the white-spot pixel.
