Claims

[Scope of utility model registration request]

a light-receiving element that receives subject light that has passed through a photographic optical system and reflected from a film surface; and a strobe control circuit that integrates the light-receiving output of the light-receiving element and generates a strobe light emission stop signal when a predetermined integral value is reached. An adapter device that is detachably attached to a part of a film camera to which a back cover is attached, comprising: a light-transmitting diffuse reflection optical element disposed at a position corresponding to the film surface of the camera; and the optical element. a relay optical system that forms an image of the transmitted light at a position away from a position corresponding to the film surface; an image sensor that is placed at the image formation position of the relay optical system; 1. A still video adapter device for a film camera, comprising an imaging control circuit for controlling the camera.
