ABSTRACT:
A method of restoring a color image comprised of one or more colorants and which image may have faded over time, which image is represented by an image signal. The method uses both a restoration model and provides a means which enable a user to readily interact with the restoration process to obtain a final restoration. In a second aspect, the restoration model is used in conjunction with a lightness distribution mapping to provide a high quality restoration. The restoration model is a function of a variable time, and is the inverse of a model representing the fade rate of at least one of the colorants as a function of at least a variable time (and preferably also as a function of the other colorants). An apparatus for performing the method is provided. A computer readable medium has computer readable code means which can execute the method in a suitable computer.
