ABSTRACT:
A voltage adjusting apparatus which may be used in a camera. Digital signals from a data setting member are directed by a central processing unit to a random access memory and from there to a digital to analog converter. The output of the converter and a reference voltage are processed in an operational amplifier to produce an output voltage. If the output voltage is not within a desired range, new signals are supplied from the data setting member.
