Abstract
A system and method of eliminating closed or partially closed eyes of subject in photography, caused by subjects blinking at the moment of image capture. A digital camera is configured to capture two images in quick succession. The image processing unit of the camera identifies regions of difference between the two images that indicate that eyes are partially or fully closed in one of the two images, and creates a single composite image from the two original images, in which all eyes are open for all subjects in the image.
