Partial Face Detector Red-Eye Filter Method and Apparatus
First Claim
1. A portable digital image capturing device having no photographic film, comprising:
- a flash for providing illumination during image acquisition;
an optical system including a lens and an image sensor for capturing a digital image;
one or more dedicated hardware units, including;
one or both of a face or a partial face detector subsystem for providing hardware-based identification of one or more face or partial face regions, or a combination thereof, within the digital image.

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 at least one partial face region identified within the digital image for the red-eye phenomenon and modifies the 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.
