Abstract:
1. An image processing apparatus, comprising a representative face extraction circuit configured to detect face images in an image frame that forms part of video image data, and select, from the detected face images, a face image to be used as index information, wherein said representative face extraction circuit is configured to calculate a score of each of the face images detected in the image frame based on characteristics of the face image, and wherein said representative face extraction circuit is further configured to (i) calculate a position score of each of the face images detected in the image frame, the position score increasing in value as the face image is closer to a center of the image frame, (ii) calculate a size score of each of the face images detected in the image frame, the size score increasing in value as a size of the face image increases, iii) calculate a face evaluation value score of each of the face images detected in the image frame, the face evaluation value score increasing in value as an extent of face likeliness of the face image increases, and (iv) calculate an aggregate score of each of the face images using the position score, the size score, and the face evaluation value score, and select a detected face image whose aggregate score is high as an index-use face image.
