An image pickup apparatus includes a photoelectric conversion element which photoelectrically converts an optical image formed by an imaging optical system to acquire image data, a read control unit which thins out pixels, as needed, and reads the image data acquired by the photoelectric conversion element, a region setting unit which sets the region of an output image, a read rule selection unit which selects the pixel thinning read rule of the read control unit, and a distortion correction unit which corrects distortion of the image data read from the photoelectric conversion element. The distortion correction unit includes a filter processing unit which executes filter processing for the image data, and a filter coefficient setting unit which sets the filter coefficient of the filter processing unit in accordance with the pixel thinning read rule.
