Imaging apparatus and method for controlling same

An imaging apparatus comprising:

• an acquiring unit configured to acquire an image signal output by a plurality of photoelectric conversion units configured to output a plurality of image signals by photoelectrically converting light fluxes each having passed through a different pupil region of an imaging optical system and a combined image signal by combining image signals corresponding to the light fluxes each having passed through the different pupil regions of the imaging optical system among the plurality of image signals;
• a parallax map generating unit configured to generate parallax map data based on an image signal corresponding to a region which is one of a pair of the pupil regions among the plurality of image signals;
• and
• a recording unit configured to generate a single Design rule for Camera File system (DCF) image file including the combined image data and the parallax map data, and record the DCF image file in a recording medium.

A control method which is executed by an imaging apparatus, the method comprising:

• outputting, by a plurality of photoelectric conversion units, a plurality of image signals by photoelectrically converting light fluxes each having passed through a different pupil region of an imaging optical system;
• generating a combined image signal by combining image signals corresponding to the light fluxes each having passed through the different pupil regions of the imaging optical system among the plurality of image signals output by the plurality of photoelectric conversion units;
• generating parallax map data based on an image signal generated from the signal corresponding to a region which is one of a pair of the pupil regions;
• and
• creating a single Design rule for Camera File system (DCF) image file including the combined image data and the parallax map data, and record the DCF image file in a recording medium.
