Patent Images
1. A method of processing a digital image using face detection to achieve one or more desired image processing parameters, comprising:
- (a) identifying a group of pixels that correspond to a face image within the digital image;
(b) detecting a skin tone for the face image by determining one or more default color or tonal values, or combinations thereof, for the group of pixels; and
(c) adjusting values of one or more parameters for the group of pixels that correspond to the face image based on the detected skin tone.

Abstract
A technique for processing a digital image uses face detection to achieve one or more desired image processing parameters. A group of pixels is identified that corresponds to a face image within the digital image. A skin tone is detected for the face image by determining one or more default color or tonal values, or combinations thereof, for the group of pixels. Values of one or more parameters are adjusted for the group of pixels that correspond to the face image based on the detected skin tone.
