A passive infra-red ranging system for a photographic camera or the like includes two infra-red responsive sensors spaced apart a predetermined distance from one another on the camera body. Each sensor includes a plurality of vertically aligned segments which receive a portion of the infra-red radiation emitted from the subject(s) of principal interest. In one embodiment, the segments of the two sensors are scanned in a successive serial manner by scanning circuitry with the composite output of each sensor analyzed to identify the maxima(s) associated wi...
A passive ranging system for photographic apparatus, said system comprising: means for sensing infrared radiation emitted by one or more subjects in a scene to be photographed, said sensing means including first and second sensor members of given length spaced apart a predetermined distance in a given direction and means for imaging radiation from a subject on said sensor members; means for comparing the position of the subject image defined by said emitted radiation on each said sensor member as measured along said given direction and, in accordance the...
