ABSTRACT:
A photographing information display circuit for a camera which performs digital computation of information relative to exposure, etc. and displays the computed digital values. The display of the digital value computed is effected through an analog display circuit such as a meter circuit by an extremely simplified circuit arrangement, without using any D-A conversion circuit such as a ladder circuit or the like. The invented display circuit arrangement minimizes the electric power requirement for display to solve the problem of electric power consumption for display in small-sized camera.
