Abstract

An image pickup apparatus includes an image pickup unit to pick up an image of a subject which a user desires. The image pickup apparatus detects a face image area which includes a face of the subject person in the picked-up image based on the image information of the picked-up image, recognizes an expression of the face in the detected face image area, ranks the face image areas in order of good smile from among the recognized expressions, and displays the face image areas arranged in the order of ranking and the entire picked-up image on a same screen.

Claims
