Abstract: A focus position detection apparatus calculates, for each shift amount calculation area in a measurement area set on an image sensor of a camera, a local shift amount between a first sub-image generated by first pixels and a second sub-image generated by second pixels, and a degree of reliability of the local shift amount, and corrects the degree of reliability base on a level of inclusion of components included in a subject image in the shift amount calculation area and being finer than a distance between two adjacent first pixels or a distance between two adjacent second pixels. The focus position detection apparatus then calculates a representative value representing a distance between a focus position by an optical system of the camera and the image sensor so that influence of the local shift amount of each shift amount calculation area increases as the corrected degree of reliability increases.
