SILVER SALT CAMERA WITH ELECTRONIC VIEW FINDER

摘要

PROBLEM TO BE SOLVED: To perform the image picking-up of an electronic view finder at a shutter speed equal to a photographing shutter speed on a silver salt film side without providing a complicated diaphragm mechanism on an electronic view finder side with respect to a silver salt camera with the electronic view finder. SOLUTION: This camera is provided with a silver salt photographing means 200 which has a diaphragm means 212 for a film capable of changing a stop value obtained when an incident luminous flux is converged and performs photographing on a silver salt film, an electronic view finder means 300 which has a diaphragm means 322 for a solid state imaging device capable of changing the stop value stepwise obtained when the incident luminous flux is converged and displays an image picked up by the solid state imaging device, and a control means 100 controlling the shutter speed of the silver salt photographing means from an exposure value; and the means 100 controls the shutter speed of the electronic view finder means to nearly coincide with that of the silver salt photographing means and controls the stop value of the diaphragm means for the solid state imaging device of the electronic view finder means and the amplification factor of an image pick-up signal so that an adequate exposure can be obtained at this shutter speed.
