1. A method for processing super-pixel representations of physical images being processed for subsequent presentation by diffusing error values derived by taking differences between input and output portions of the physical images being processed, the error values being diffused with respect to a selected super-pixel of predetermined dimensions and residing in a predetermined super-pixel neighborhood, and further with respect to selected subject pixels within the selected super-pixel, each of the subject pixels within the selected super-pixel having an assigned error value, the method comprising the steps of: distributing at least a portion of the error value of a selected first subject pixel to another subject pixel within the selected super-pixel, whereby a final resultant error value is established for said another subject pixel; establishing a final pixel error value for the selected super-pixel; and distributing at least a portion of the final pixel error value to selected super-pixels within the predetermined super-pixel neighborhood of the selected super-pixel.
