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.
Claims20
A method of processing a digital image using face detection to achieve one or more desired image processing parameters, comprising:
- identifying a group of pixels that correspond to a face image within the digital image;
- 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
- adjusting values of one or more parameters for the group of pixels that correspond to the face image based on the detected skin tone.
An image acquisition apparatus including an imaging optical system and digital image detector and storage medium, and having stored therein program instructions for programming one or more processors to perform a method of processing a digital image using face detection to achieve one or more desired image processing parameters, the method comprising:
- identifying a group of pixels that correspond to a face image within the digital image;
- 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
- adjusting values of one or more parameters for the group of pixels that correspond to the face image based on the detected skin tone.
One or more digital storage devices having embodied therein program instructions for programming one or more processors to perform a method of processing a digital image using face detection to achieve one or more desired image processing parameters, the method comprising:
- identifying a group of pixels that correspond to a face image within the digital image;
- 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
- adjusting values of one or more parameters for the group of pixels that correspond to the face image based on the detected skin tone.
