Performance evaluation of 3D-TV systems

The image quality circle is a commonly accepted framework to model the relation between the technology variables of a display and the resulting image quality. 3D-TV systems, however, go beyond the concept of image quality. Research has shown that, although 3D scenes are clearly more appreciated by subjects, the concept ’image quality ’ does not take this added value of depth into account. Concepts as ’naturalness ’ and ’viewing experience ’ have turned out to be more useful when assessing the overall performance of 3D displays. In this paper, experiments are described that test ’perceived depth’, ’perceived image quality ’ and ’perceived naturalness’ in images with different levels of blur and different depth levels. Results show that naturalness incorporates both blur level as well as depth level, while image quality does not include depth level. These results confirm that image quality is not a good measure to assess the overall performance of 3D displays. Naturalness is a more promising concept
