Patent ID: 8730374

Claim:
An image capture apparatus comprising: an image sensor including a plurality of image forming pixels that photo-electrically convert an object image formed by an imaging lens and generate an image generation signal, and focus detection pixels that are arranged discretely between the plurality of image forming pixels and that divide a pupil region of the imaging lens, photo-electrically convert an object image from the divided pupil region and generate a phase difference detection signal; a first focus detection unit configured to perform focus detection by a phase difference detection method by using the phase difference detection signal from the focus detection pixels; a second focus detection unit configured to detect an image contrast from the image generation signal from the image forming pixels and performing focus detection by a contrast detection method; an orientation detection unit configured to detect an orientation of the image capture apparatus; and a correction value calculation unit configured to calculate a correction value for a result of focus detection by the first focus detection unit based on a difference between the result of focus detection by the first focus detection unit and a result of focus detection by the second focus detection unit, wherein the correction value calculation unit does not calculate the correction value when the orientation detection unit detects that a change in the orientation of the image capture apparatus between the time of focus detection by the second focus detection unit and the time of focus detection by the first focus detection unit is larger than a prescribed amount.
