A STUDY OF VISUAL DISPLAY ENHANCEMENT AND TECHNIQUES OF COLOR FILTERING,
Abstract
An investigation zs reported of target detection as a function of the spectral partitioning of light energy received from multicolored scenes which contain the targets and as a function of observer opportunity to manipulate certain viewing conditions. One group of observers viewed black and white photographs taken without optical filtering. Two others viewed black and white photographs taken through blue and orangeyellow filters. Observers in one of the latter groups were given complete control of the display facilities, permitting them to view the orange-yellow and blue-filtered images singly, alternately or superimposed. Observers in the other group had more limited control of the display; they could view the two filtered images singly, changing from one to the other as often as desired, but with a brief pause between images. Viewing the two filtered photographs proved superior to viewing the unfiltered one. Differences resulting from the two degrees of display control were small but favored the condition of more complete observer control. Preliminary studies are described in an appendix. (Author)
