ABSTRACT:
An exposure control apparatus for a photographic camera wherein various exposure control parameters after being digitized are applied to a computer. The computer then derives an exposure value based on digital computation. The apparatus is provided with combined means for converting the preselected exposure control parameters to corresponding mechanical displacements and for converting the displacements directly to corresponding numbers of pulses, whereby the computer is made responsive to the numbers of pulses.
