Optimized Performance and Performance for Red-Eye Filter Method and Apparatus
First Claim
1. :
- A digital apparatus, comprising;
(a) an image store for holding;
(i) a temporary copy of an unprocessed image known as a pre-capture image;
(ii) a permanent copy of a digitally processed, captured image, and (iii) a subsample representation of selected regions of the pre-capture image; and
(b) a red-eye filter for modifying an area within said at least one of the images indicative of a red-eye phenomenon based on an analysis of the subsample representation, and on an analysis of meta-data information.

Abstract
A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.
