Patent ID: 8103158

Claim:
An image sensing apparatus capable of continuous shooting, comprising: a defocus amount detection unit which detects a defocus amount in each of a plurality of focus detection areas in every shooting operation during continuous shooting; a photometry unit which has a plurality of photometry areas corresponding to the plurality of focus detection areas and performs photometry in each of the plurality of photometry areas in every shooting operation during continuous shooting; a weighting unit which determines a weighting of each of the plurality of photometry areas based on defocus amounts detected by the defocus amount detection unit; and an exposure determination unit which determines an exposure for image sensing in every shooting operation during continuous shooting, wherein in one shooting operation during continuous shooting, when the weighting unit can determine weightings of the plurality of photometry areas till a next successive shooting operation, the exposure determination unit determines the exposure by calculating a weighted average of photometric values of the plurality of photometry areas using the weightings determined by the weighting unit, and when the weighting unit cannot determine the weightings of the plurality of photometry areas till the next successive shooting operation, the exposure determination unit determines the exposure by calculating a weighted average of the photometric values of the plurality of photometry areas using weightings which have been determined by the weighting unit in a shooting operation preceding the one shooting operation.
