Patent ID: 8849035

Claim:
An image processing apparatus for detecting a face in an image using a plurality of discriminations, the image processing apparatus comprising: a setting unit configured to set a a plurality of thresholds used for the plurality of discriminations, such that, as a face size of a detection target in an image is smaller, a higher threshold is set to reduce incorrect detection of an area that is not a face; and a detecting unit configured to calculate a plurality of evaluation values from an area corresponding to the face size of the detection target in the image using the plurality of discriminations, and to detect a face in the image using the plurality of thresholds set by the setting unit and the plurality of calculated evaluation values, wherein the detecting unit stops detecting in the area based on a result of comparing an evaluation value calculated by at least one discrimination of the plurality of the discriminations with at least one threshold of the plurality of thresholds set by the setting unit.
