Abstract
An image processing system and method for determining an intrinsic color component of one or more objects present in a sequence of frames, for use in rendering the object(s), are described. Some of the frames of the sequence are to be used as lighting keyframes. A lighting estimate for a lighting keyframe A of the sequence of frames is determined. A lighting estimate for a lighting keyframe B of the sequence of frames is determined. A lighting estimate for an intermediate frame positioned between the lighting keyframes A and B in the sequence is determined by interpolating between the lighting estimates determined for the lighting keyframes A and B of the sequence. The determined lighting estimate for the intermediate frame is used to separate image values representing the object(s) in the intermediate frame into an intrinsic color component and a shading component, for use in rendering the object(s).
