Abstract
The present invention discloses a method for automatically detecting and correcting red eye in a photo taking process. The method utilizes a preview function which all of the current digital cameras have. When flash light is needed during the photo taking process, an image which is closest to the shutter pressing time is read from a preview image sequence and this image is stored. Then, red eye detection is performed according to various related information (e.g., chroma information) of this image and the image actually taken. A correction process is conducted on the detected red eye area. The corrected image is stored as a resulting image in a storage unit in the camera. Therefore, the red eye is removed rapidly and accurately during a single normal exposure process and the image without red eye is thus obtained.
