apparatus and a method for reducing red-eye in an image

Abstract

Abstract A red-eye reduction system (10) includes a masking module (16) which converts an image (11) into a mask having first state areas representing red colour pixels of the image and second state areas representing other colour pixels of the image. The image (11) includes an eye with a red pupil. A pupil locating module (17) is coupled to the masking module (16) to locate a substantially first state area in the mask that resembles a pupil. A colour replacing module (18) is then coupled to the pupil locating module (17) to change the red colour pixels in the area into monochrome (grey) or other predefined colours. The colour replacing module (18) also adjusts the boundary of the area by changing the colours of pixels in close proximity to the area if the colour of these pixels is determined to be sufficiently close to red such that natural appearance of the eye is maintained when reducing the red pupil.
