Patent ID: 8085996

Claim:
An image processing apparatus comprising: means for storing a plurality of evaluation information sets for determinations as to whether a face image is a target image, each of the evaluation information sets identifying at least two positions in the face image; means for inputting an image; means for detecting a face included in the input image; means for normalizing the face image that is an image segment including the detected face so that the face image has a predetermined resolution; means for extracting brightness values of the normalized face image at the two positions identified in each of the evaluation information sets; and means for calculating a difference between the brightness values of the normalized face image at the two positions identified in each of the evaluation information sets, and making a determination on the basis of the calculated difference and each evaluation information set stored in the means for storing as to whether the face image is the target image associated with the evaluation information set, and generating an attribute information block related to the face included in the face image as a result of the determination.
