Data recording apparatus, image capturing apparatus, data recording method, and storage medium

An image capturing apparatus comprising:

• an image capturing unit capable of capturing a plurality of images of different focus positions and different viewpoints;
• an input unit configured to input, from the image capturing unit, an image data group including at least:
• image data obtained by performing image capturing at a first focus position from a first viewpoint;
• image data obtained by performing image capturing at a second focus position different from the first focus position from the first viewpoint;
• and
• image data obtained by performing image capturing at the first focus position from a second viewpoint different from the first viewpoint;
• and
• a recording unit configured to generate management information that associates each piece of image data of the image data group that is input by the input unit and to record the generated management information and the image data group in a storage medium in accordance with a predetermined format.

A data recording method comprising:

• an input step of inputting an image data group including at least:
• image data obtained by performing image capturing at a first focus position from a first viewpoint;
• image data obtained by performing image capturing at a second focus position different from the first focus position from the first viewpoint;
• and
• image data obtained by performing image capturing at the first focus position from a second viewpoint different from the first viewpoint;
• and
• a recording step of generating management information that associates each piece of image data of the input image data group and recording the generated management information and the image data group in a storage medium in accordance with a predetermined format.
