Image Identification on Television

Abstract

Four experiments were conducted to measure identification of photographs of geometric symbols and military vehicles both on TV and by direct vision. The number of TV scan lines per image and image angular subtense were systematically varied. The background against which the vehicles were photographed was also varied. The mean performance of symbol legibility on TV followed a constant-product rule. Vehicle identification performance also varied as a function of the type of background. Direct-vision performance was used to estimate the degradation resulting by interposing the TV system between the observer and the photographs.
