Under current practice, copier manufacturers tend to let their designers rely on subjective judgment in designing the quality of the copy image. The designers'preferences, however, do not necessarily match those of consumers, so it has become necessary to find objective image evaluation criteria. In previous studies,although the MT system proved effective when applied to the evaluation of monochrome image quality, there remailed problems of suitability in the evaluation stage. In the present study, an objective and highly reliable evaluation method for copy images was constructed by using signals free of subjective factors and applying the MTA method.
