发明名称 Image sensing apparatus having exposure control and method therefor
摘要 In an image sensing apparatus and exposure control method, detecting an object that satisfies a certain preset condition from image data obtained by image sensing with an image sensing element, and carrying out photometry on the image data as a whole to acquire an overall photometric value while carrying out photometry on an area of a detected object within the image data to acquire an object photometric value. An exposure value is then determined based on the overall photometric value and the object photometric value, with exposure controlled during image sensing based on the determined exposure value.
