Abstract
In a photographic camera having a plurality of opto-sensors and a microprocessor-based controller, the opto-sensor output signals are coupled via a common bus connection to an input terminal of the controller. A programmably variable output impedance common to the opto-sensors is selectably set for each corresponding selected opto-sensor such that the output signal for each of the selected opto-sensors is at or above a predetermined threshold value at the input to the controller irrespective of differing current output performance of the individual opto-sensors.
