Title:
IMAGE ENHANCEMENT BASED ON MOTION ESTIMATION
Document Type and Number:
WIPO Patent Application WO2006046204
Kind Code:
A3
Abstract:
A set of images (IM1a, IM2a, IMFa) that have successively been captured comprises a plurality of images (IM1a, IM2a) that have been captured under substantially similar light conditions, and an image (IMFa) that has been captured under substantially different light conditions (FLSH). For example, two images may be captured with ambient light and one with flashlight. A motion indication (MV) is derived (ST6) from at least two images (IM1a, IM2a) that have been captured under substantially similar light conditions. The image (IMFa) that has been captured under substantially different light conditions is processed (ST7, ST8) on the basis of the motion indication (MV) derived from the at least two images (IM1a, IM2a) that have been captured under substantially similar light conditions.
