Claim One:
1. A human face detection device, comprising: a photosensitive element, for capturing a first image containing a first human face block; a human face detection unit, for comparing the first image with at least one human face feature, so as to detect the first human face block; and a skin color threshold generation unit, for updating a skin color threshold value according to color of the detected first human face block; wherein the skin color threshold value is used for filtering the first image to obtain a candidate region, the human face detection unit compares the candidate region with the at least one human face feature to obtain the first human face block, the skin color threshold generation unit generates an updated skin color threshold value according to a color value of a human face region when the first image has the human face region, and the skin color threshold value is used for determining whether the first human face block detected by the human face detection unit is correct.
