Abstract:
An image capture apparatus includes a photometry unit, which performs photometry of luminance in each of the photometry areas in an image sensing scene, a photometry mode determination unit, which determines a photometry mode, a filter operation unit, which performs an operation on a luminance value of a photometry area by taking into account luminance values of photometry areas around the photometry area, and an exposure value determination unit, which determines an exposure value without using a result of the operation by the filter operation unit when the photometry mode determination unit determines that the photometry mode is a first photometry mode, and when the photometry mode determination unit determines that the photometry mode is a second photometry mode, determines the exposure value by performing an operation in accordance with the second photometry mode after the operation performed by the filter operation unit.
