Patent ID: 7830446

Claim:
An image sensing apparatus comprising: an image sensing preparation member actuable by a user; an image sensing operation member actuable by the user; a first exposure level calculation device which, upon actuation of the image sensing preparation member, calculates a first exposure level based on a result of photometry, the first exposure level calculation device carrying out further processing if the image sensing operation member is actuated prior to completion of the calculation of the first exposure level, the further processing carried out by the first exposure level calculation device including determining whether the image sensing apparatus is in a predetermined mode or a manual exposure has been set, and, if so, the first exposure level calculation device continuing calculation of the first exposure level until completion of calculation of the first exposure level and, if not, the first exposure level calculation device discontinuing calculation of the first exposure level; a second exposure level calculation device which calculates a second exposure level of an image signal output after image sensing; an exposure error calculation device which calculates an exposure error between the first exposure level calculated by said first exposure level calculation device and the second exposure level calculated by said second exposure level calculation device; and an exposure error correction device which performs a correction operation of the exposure error by using the exposure error calculated by said exposure error calculation device, when said image sensing apparatus is in an auto exposure control mode, wherein said exposure error correction device does not perform the correction operation if the first exposure level calculation device carried out further processing and determined that the image sensing apparatus is in the predetermined mode or manual exposure has been set.
