Method of processing digital image to correct for flash effects
First Claim
1. A method of processing an image captured by a digital camera said digital camera comprising a digital image sensor means, self-contained processor means, memory means and a flash, said method of processing being performed within and by said processor means of said digital camera and comprising the steps of:
- a) locating distortions of said captured image due to the utilisation of said flash;
b) retouching said image so as to locally reduce the effect of said distortions.

Abstract
An image captured by a digital camera with a flash is processed by locating distortions of said captured image due to said flash such as “red-eye” effects and removing them. The process includes the steps of determining if the flash is on (step 11), if so, determining any faces within the captured image (step 12), locating eyes within said faces (step 13), determining if “red-eye” removal is required (step 14), and if so, correcting for such effects (step 15) and storing corrected image (step 16) in a memory device of the digital camera.
