Comparing Visual Realness between High Resolution Images and Real Objects

Abstract (in Japanese) (See Japanese page) 
(in English) We performed subjective assessments to quantify the sensation of realness of images at various angular resolutions and that of their real-object counterparts using a paired-comparison procedure. Both the images and real objects were viewed through a synopter, which removed horizontal disparity and presented the same images to both eyes. The size, perspective, luminance, and chromaticity of the images were reproduced to be identical to those of the real objects. Eighty-two observers with normal vision were asked to choose the viewed image that appeared closer to the real object for each pair. The results indicated that the realness of images increased as the image resolution steadily increased up to around 60 cpd (cycles per degree), whereafter it gradually approached that of the real objects.
