Recent changes show that the goals of reproduction devices have changed from accurately reproducing scenes to improving user preferences. It implies that the directions in developing cameras, the most common reproduction devices, are moving from performance -centered to quality-centered, from developers to users. Accepting such changes demand new standards in evaluating reproduction devices. This paper suggests a new method to evaluate the quality of images, based on cognitive properties of users. Through precedent studies and analysis, elements that effect the quality of images has been classified, and the applicability of the model has been assessed with preliminary tests. The classified elements are detail, tone reproduction and color reproduction. Presuming that the elements influence one and other, numbers of hypothesis were drawn to meet each item. 1,015 test stimuli had been produced to verify the hypothesis, and 84 test stimuli were selected by user preference. The experiment was carried out to 127 subjects, with the 84 test stimuli and 11 evaluation factors, followed by an analysis using structural equation modeling. Final evaluation model suggested is on the basis of the test results.
