Patent ID: 8643738

Claim:
A face detection device, comprising: a first face detector which detects face areas from a plurality of through images; a second face detector which detects a face area from a shooting image, wherein a scene shot in the shooting image corresponds to the scene shot in one of the plurality of through images, and wherein the second face detector has higher detection accuracy than the first face detector; and a control unit which extracts a non-detected area in the scene, wherein the non-detected area in the shooting image is detected as a face area in the second face detector but the non-detected area in the one of the plurality of through images is initially not detected as a face area in the first face detector, and wherein the control unit executes learning of the first face detector based on the non-detected area in the shooting image; and wherein the non-detected area in the one of the plurality of through images is subsequently detected as a face area in the first face detector after the learning.
