发明名称 FOCUS DETECTION APPARATUS
摘要 An image capture apparatus includes: an image sensor including a plurality of image forming pixels that generate an image generation signal, and focus detection pixels 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 using the phase difference detection signal; 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; 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.
