Abstract:
An image capturing apparatus includes a zoom lens, a solid-state image sensor which photoelectrically converts an image formed by the zoom lens, a processing unit which processes image data obtained by the solid-state image sensor, and a correction units which processes the image data from the processing unit to correct distortion aberration of the image formed by the zoom lens, and outputs the corrected image data. The lens arrangement of the zoom lens, and the length of the diagonal line of the image capturing area in correcting distortion aberration are appropriately set.
