METHOD AND APPARATUS FOR IMAGE CAPTURING CAPABLE OF EFFECTIVELY REPRODUCING QUALITY IMAGE AND ELECTRONIC APPARATUS USING THE SAME

摘要

An image capturing apparatus includes an imaging lens, an image pickup device, and a correcting circuit. The imaging lens is configured to focus light from an object to form an image. The image pickup device is configured to pick up the image formed by the imaging lens. The correcting circuit is configured to execute computations for correcting image degradation of the image caused by the imaging lens. The imaging lens is also a single lens having a finite gain of optical transfer function and exhibiting a minute difference in the gain between different angles of view of the imaging lens.
