Camera
First Claim
1. A camera for performing a first image formation and a second image formation by splitting a light beam incident through a taking optical system including a first aperture diaphragm, said first image formation being performed with a silver salt medium, said second image formation being performed electronically with an image pickup device, comprising:
- an image forming optical system disposed in a light path of one of said split light beams for directing the light beam toward the image pickup device;
a second aperture diaphragm disposed in a light path within said image forming optical system; and
a controller for controlling said first and second aperture diaphragms correlatively.

Abstract
A camera divides a light beam having passed through a taking lens unit into two light beams. One light beam forms an image on a silver salt film. Another light beam forms an image on a CCD. A light path for said another light beam is provided with an aperture diaphragm. The taking lens unit has an aperture diaphragm. Said two aperture diaphragms are correlatively controlled by a controller incorporated in the camera.

17. A camera which splits a light beam incident through a taking optical system including a first aperture diaphragm, one of split light beams being used for image formation on a photosensitive recording medium, another of the split light beams being used for image formation on an image pickup device for observation through an electronic viewfinder, comprising:
-
a setting device for setting an aperture value of said first aperture diaphragm; a second aperture diaphragm disposed in a light path of said another light beam; and a controller for driving said first aperture diaphragm based on a setting by said setting device during image formation on said photosensitive recording medium, and for driving said second aperture diaphragm based on a setting by said setting device except during image formation on said photosensitive recording medium to perform image formation with said image pickup device so that a formed image is displayed in the electronic viewfinder. - View Dependent Claims (18, 19)

20. A camera which splits a light beam incident through a taking optical system, one of split light beams being used for image formation on a photosensitive recording medium through a shutter, other of split light beams being used for image formation with an image pickup device so that a formed image is observed through an electronic viewfinder, comprising:
-
a setting device for setting a control shutter speed of said shutter; and a controller for driving said shutter based on a setting by said setting device during image formation on said photosensitive recording medium, and for controlling an electric charge accumulation time of said image pickup device except during image formation on said photosensitive recording medium to perform image formation so that a formed image is displayed in the electronic viewfinder. - View Dependent Claims (21, 22)
