Abstract
Preferred viewing distance (PVD), which is the viewing distance favored in the home viewing environment, is important for overall TV broadcasting system assessments to guarantee the image quality of TV programs. Previous studies have suggested that image size and resolution have little effect on the PVD. However, in future TV systems such as ultra-high-definition TVs (UHDTVs), which are expected to have a wide field of view (FOV) and high spatial resolution, program production methods may change depending on the specific values of these parameters, and viewer behaviors may change accordingly. Here we used a program consisting of still images to show that viewer behavior differs between two spatial resolutions. This result suggests that the conditions in previous studies discouraged viewers from finding an optimized PVD for each scene because there was little need and insufficient time to move spontaneously.
