Abstract

Two investigations were set up into the dependence of the human sharpness impression in complex scenes on velocity and resolution. Sequences, in which a portrait was moving horizontally at a constant speed, were presented on a high-resolution monitor (velocities between 0.5 and 35 deg/s). Both a maximum resolution version and bandwidth-reduced versions were presented. Subjects assessed the (subjective) sharpness of the stimuli on a categorical scale. The results show that for the maximum resolution images, there is hardly any change in perceived sharpness as a function of velocity. Furthermore, for the low resolution images, we find an increase in sharpness with velocity, which implies that the perceived sharpness range is compressed at those velocities.
