1. An imaging apparatus comprising:
an image sensor that captures a subject image to generate image data;
a depth measurer that acquires depth information indicating a depth to a subject in an image indicated by the image data;
a detector that acquires subject detection information on a region where the subject of a predetermined type is located in the image; and
a recognizer that recognizes a subject region having a shape along the subject in the image, based on the depth information and the subject detection information, wherein
the subject detection information indicates a detection region where the subject of the predetermined type is detected in the image, and
the recognizer recognizes a specific region included in the detection region as an individual subject region, based on the subject detection information and the depth information, the detection region having an overlap between a plurality of subjects in the image, the specific region having a common depth indicated by the depth information in the detection region indicated by the subject detection information, the individual subject region indicating each subject of the plurality of subjects.
