Abstract:
An image pick-up apparatus comprising:(a) a first image pick-up optical system having a first variable aperture capable of changing a first aperture value;(b) a first image pick-up device for picking up an object image incident through said first image pick-up optical system, and converting said object image to an electric image signal;(c) a second image pick-up optical system having a second variable aperture capable of changing a second aperture value, said second variable aperture serving also as a shutter;(d) a silver halide photographing component for photographing an object image incident on a silver halide film through said second image pick-up optical system, photographing on said silver halide film being started when said second variable aperture starts moving from its closed position toward its open position;(e) range finder for measuring a distance to an object;(f) an electronic flash mechanism for illuminating said object; and(g) a control for determining a first determined aperture value of said first variable aperture and a second determined aperture value of said second variable aperture based upon said distance and upon a light emission capability of said electronic flash mechanism, said control causing said first variable aperture to start operations so that said first aperture value reaches said first determined aperture at the same time as said second aperture value reaches said second determined aperture value, said control causing said flash mechanism to emit light when said first aperture value and said second aperture value reach said first determined aperture value and said second determined aperture value respectively after said image pick-up device starts picking up said object image and said silver halide photographing component starts photographing.
