An image capture apparatus comprising: an image sensor having a first pixel group that photoelectrically converts an object image from a first exit pupil region that is part of an overall exit pupil region of a photographing lens, a second pixel group that photoelectrically converts an object image from a second exit pupil region that is different from the first exit pupil region, and a third pixel group for capturing that photoelectrically converts an object image from an exit pupil region that includes the first exit pupil region and the second exit pupil region; a processing unit arranged to calculate information corresponding to an amount of defocus of a lens with use of a first image signal obtained from a first pixel group in an image sensor and a second image signal obtained from the second pixel group in the image sensor, wherein the image sensor further has a third pixel group; a control unit arranged to convert captured image data that includes image data that has been photoelectrically converted by at least the third pixel group of the image sensor and image data corresponding to positions of the first pixel group and the second pixel group and generated by performing interpolation with use of information from the third pixel group, into an image file for recording and saving, and a data recording unit arranged to record in a RAW file mode, in association with the image file, signals obtained from the first pixel group and the second pixel group such that the defocus calculation can be performed, and records in a JPEG file mode, in association with the image file, a result calculated by the processing unit. an image sensor having a first pixel group that photoelectrically converts an object image from a first exit pupil region that is part of an overall exit pupil region of a photographing lens, a second pixel group that photoelectrically converts an object image from a second exit pupil region that is different from the first exit pupil region, and a third pixel group for capturing that photoelectrically converts an object image from an exit pupil region that includes the first exit pupil region and the second exit pupil region; a processing unit arranged to calculate information corresponding to an amount of defocus of a lens with use of a first image signal obtained from a first pixel group in an image sensor and a second image signal obtained from the second pixel group in the image sensor, wherein the image sensor further has a third pixel group; a control unit arranged to convert captured image data that includes image data that has been photoelectrically converted by at least the third pixel group of the image sensor and image data corresponding to positions of the first pixel group and the second pixel group and generated by performing interpolation with use of information from the third pixel group, into an image file for recording and saving, and a data recording unit arranged to record in a RAW file mode, in association with the image file, signals obtained from the first pixel group and the second pixel group such that the defocus calculation can be performed, and records in a JPEG file mode, in association with the image file, a result calculated by the processing unit.
