TARGET DETECTION USING BLACK-AND-WHITE TELEVISION. STUDY 1. THE EFFECTS OF RESOLUTION DEGRADATION ON TARGET DETECTION

Abstract

The probability of detecting an M-48 tank at four different levels of television (TV) resolution (800,600, 400, and 300 lines) was investigated on a black-and white closed-circuit TV system. The four levels of TV resolution were presented to 16 subjects, who were asked to indicate in which one of nine areas the tank appeared on the TV screen. The data indicated that subjects performed about equally well at the 800, 600, and 400 levels of resolution; however, their performance was significantly poorer at the 300 level of resolution. The tank's location on the TV screen was an important factor in the probability of target detection, but was confounded with other variables.
