We evaluated realness of real objects and images at various resolutions. Both real objects and images are viewed through a synopter, which removes horizontal disparity and presents the same image to both eyes. Sixty-five subjects evaluate the realness of three real objects and their images at six different resolutions ranging from 19.5 cpd to 156 cpd. We found that realness of image increases as the image resolution increases up to the discrimination threshold based on visual acuity and remains constant above the discrimination threshold.

We developed the Video On Demand System for the short programs (commercials, news films and other short programs) in the YOKOHAMA Broadcast Library, using TAO's (Telecommunications Advancement Organization of Japan experimental system in January 2001. We report about the storage, distribution and viewing part of the system.

This paper reports the results of a subjective assessment for stereoscopic HDTV coding using MPEG2 MVP@HL, which is a standard for stereoescopic television coding. The results of assessment for coding images of MVP are compared with those of coding images of simulcast, left and right image of which are each coded using conventional MP@HL. The image quality of MVP coding is almost as same as, or is higher than that of simulcast coding. According to the test of bit allocation to left and right images, an adaptive bit allocation depending on image contents can improve the subjective image quality.
