An image sensing apparatus which is able to detect a focus position of a lens (100) using image signal pair, including: an image sensor (107) configured to output an image signal for detecting the focus position; and a correction unit (170) configured to correct a signal level of the image signal based on correction information (176, 177), wherein the correction information is related to a light amount which changes in response to an image height and a production error which includes an alignment error at a time of forming the image sensor. |
