Perceived quality of angular resolution for light field displays and the validy of subjective assessment

Angular resolution plays a vital role in the perceived quality when displaying visual content on autostereoscopic 3D displays, since it affects the motion parallax effect. In this paper, we present the results of a subjective quality assessment carried out on a light field display, investigating the perceptual quality of visual content with different angular resolutions. We also address the question of subjective assessment validity, since the visual experience of suboptimal, reduced angular resolution is currently a completely new phenomenon for test participants.
