Abstract
A method for detecting faces in an image having a plurality of picture elements, each having a plurality of color components in a predetermined color space, includes determining an extended range for color component values, in the color space, in which a skin tone area is likely to be detected, defining intervals for the color component values, in the color space, covering at least part of the extended range, and scanning each of the intervals to detect a skin tone area. If a skin tone area is detected, the method includes selecting the intervals in which a skin tone area is detected, defining candidate limited ranges for color component values, in the color space, from the selected intervals, performing face detection on a skin tone area in at least some of the candidate limited ranges, and selecting a chosen candidate limited range based on the number of faces detected.
