ABSTRACT:
A system and method for improving digital flash photographs. The present invention is a technique that significantly improves low-light imaging by giving the end-user all the advantages of flash photography without producing the jarring look. The invention uses an image pair—one taken with flash the other without—to remove noise from the ambient image, sharpen the ambient image using detail from the flash image, correct for color, and remove red-eye.
