Abstract

It is well known that increasing the temporal sampling rate can improve the perceived quality of displayed images. The present research measured the ability of the human visual system to discriminate among different temporal sampling rates. The results of the research are intended to support the development of improved image coding and display systems. The ideal sampling rate for a moving stimulus was determined in Experiment 1. This rate is defined as the rate beyond which further increases in sampling rate have no added beneficial effect. The results showed that the ideal sampling rate depended on stimulus velocity; ideal sampling rates for velocities of 8 deg/s and 16 deg/s were about 100 Hz and 170 Hz, respectively.
