CAMERA WITH AUTO RANGING, FOCUSING AND FLASH FIRE CONTROL

摘要

6069 An automatic camera apparatus includes an integrated exposure control system comprising a sonar rangefinder for first determining camera-to-subject range and then setting the objective lens focus condition to correspond to the determined camerato-subject distance and thereafter firing an electronic flash at an appropriate exposure aperture also corresponding to the determined camera-to-subject distance in a manner providing for a proportional fill-in flash under conditions of high ambient scene light intensity.
