Patent ID: 8538142

Claim:
A face-detection processing method comprising: accessing image data of a plurality of images to be processed for detection of human faces in the images; determining whether or not to use skin-detection processing for face-detection processing of individual ones of the images based on an amount of human skin content of the individual ones of the images; and in accordance with the determining, performing the face-detection processing of one of the images using the skin-detection processing to detect human faces in the one of the images, including performing the face-detection processing using the skin-detection processing for an entirety of the one of the images based on an amount of human skin content of a portion of the one of the images being greater than a threshold, and performing the face-detection processing using the skin-detection processing except for the portion of the one of the images based on the amount of human skin content of the portion of the one of the images being less than the threshold.
