Abstract
A camera having checking function in which part of a light beam passing through the conjugate system of the camera lens unit is taken out. The light beam taken is passed through a focusing optical system to focus an optical image on an imaging device, and the imaging device outputs a picture signal corresponding to the optical image focused.
Claims7
A camera having a checking function which is composed of a silver-halide-film camera with an imaging device, comprising:
- a mirror disposed at a conjugate system of a camera lens assembly for reflecting a first part of an incident light beam,
- a focusing optical system for receiving said light part of said incident light beam reflected by said mirror and for focusing an optical image, and
- an imaging device disposed at a position where said optical image is focused by said focusing optical system for outputting a picture signal corresponding to said focused optical image, while simultaneously a second part of said incident light beam records an image on said silver-halide-film.
A camera having a checking function which is composed of a silver-halide-film camera with an imaging device, comprising:
- a combined optical system disposed at a conjugate system of a camera lens assembly for receiving a first part of an incident light beam and focusing an optical image;
- a mirror for reflecting said first part of said incident light beam passed through said combined optical system in a direction different from an optical axis of said incident light beam, and
- an imaging device disposed at a position where said light beam passed through said combined optical system and reflecting by said mirror is focused into an optical image for outputting a picture signal corresponding to said focused optical image, while simultaneously a second part of said incident light beam records an image on said silver-halide-film.
