Patent ID: 8891833

Claim:
An image processing apparatus comprising: a segmentation unit configured to segment, as to image data which has been input, the input image data being image data of a plurality of frames, image data piece included in each of the plurality of frames into a plurality of segments to create a plurality of segmented image data pieces for each of the plurality of frames; a detection unit configured to execute, as to the plurality of segmented image data pieces which has been input, face detection processing for detecting a face area from each of the plurality of input segmented image data pieces; a recognition unit configured to execute recognition processing for determining whether the face detected by the detection unit is a face of a registered person, in each of the plurality of segmented image data pieces which has been input; and a control unit connected to the detection unit and the recognition unit, and configured to control whether to cause the recognition unit to execute the recognition processing as to each of the plurality of segmented image data pieces, wherein, in a case where a first area of a first frame included in the plurality of frames satisfies predetermined conditions and a second area of the first frame does not satisfy the predetermined conditions, the control unit causes the recognition unit to execute the recognition processing for segmented image data piece which, among a plurality of segmented image data pieces created from a second frame included in the plurality of frames, corresponds to the first area of the first frame, and causes the detection unit to execute the face detection processing without causing the recognition unit to execute the recognition processing for segmented image data piece which, among the plurality of segmented image data pieces created from the second frame, corresponds to the second area of the first frame, and wherein the predetermined conditions include a condition that the face area has been detected by the detection unit.
