Abstract
A method for the digital manipulation of a video image, in which an object is located and replaced by another object. To account for ambient lighting effects, a base set of appearance parameter values for the first object is determined, such as average values of hue, saturation and luminance. Selected regions of the object are analysed and in respect of each selected region the extent to which actual appearance parameter values deviate from the base set of apparatus parameter values is determined. The method includes storing data representation of the positions of the regions and the respective deviations from the base set of values. The first object is replaced by a second object, and the method then includes the step of applying to regions of the second object adjustments to appearance parameter values by reference to the stored data.
