Abstract
Abstract A camera is disclosed which includes elements for recording an image on photographic film and a solid-state image sensor for recording an electronic image. In order to reduce the size and complexity of the camera and to improve the camera performance, the electronic and film recording functions of the camera are integrated. The solid-state image sensor is used both in controlling the recording of an image on film and in producing an electronic image.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A camera of the single lens reflex type, said camera comprising: means for forming an image on photographic film, said forming means including optical means for producing an image of an object to be photographed; means for producing an electronic image signal, said producing means including means for sensing scene parameters and for controlling said forming means in accordance with values of said parameters, said sensing and controlling means including means for focussing said optical means and for controlling the exposure of said film; display means for receiving said image signal and for producing an image therefrom; and a viewfinder for viewing said object and for viewing an image on said display means, said viewfinder being optically coupled to said optical means by means of a reflecting surface.
Claim 2
Dependent Claim
128 words
A camera of the single lens reflex type, said camera comprising: means for forming an image on photographic film, said forming means including optical means for producing an image of an object to be photographed; means for producing an electronic image signal, said producing means including means for sensing scene parameters and for controlling said forming means in accordance with values of said parameters, said sensing and controlling means including means for focussing said optical means and for controlling the exposure of said film; display means for receiving said image signal and for producing an image therefrom; and a viewfinder for viewing said object and for viewing an image on said display means, said viewfinder being optically coupled to said optical means by means of a reflecting surface.
Claim 3
Dependent Claim
16 words
A camera, as defined in claim 1, wherein said producing means includes a solid-state image sensor.
Claim 4
Dependent Claim
15 words
A camera, as defined in claim 2, wherein said producing means includes image storage means.
Claim 5
Dependent Claim
25 words
A camera, as defined in claim 3, wherein said producing means includes a system controller for controlling the functions of said camera in timed sequence.
Claim 6
Dependent Claim
165 words
A camera comprising: optical means including at least two lens elements for forming an image of an object to be photographed, said optical means including a beam splitter located between said lens elements for directing a first portion of light entering said optical means to a first location and the remainder of said light to a second location, said optical means further including light control means for controlling the amount of light which is directed to said locations in response to a signal indicative of ambient light; means for supporting a photographic film in one of said locations, said supporting means being located in an image plane of said optical means; a solid-state image sensor disposed in the other of said locations to receive light from said optical means, said solid-state image sensor including means for generating said signal; display means for displaying an image sensed by said solid-state image sensor; and a viewfinder which includes means for viewing said object and said display means.
Claim 7
Dependent Claim
165 words
A camera comprising: optical means including at least two lens elements for forming an image of an object to be photographed, said optical means including a beam splitter located between said lens elements for directing a first portion of light entering said optical means to a first location and the remainder of said light to a second location, said optical means further including light control means for controlling the amount of light which is directed to said locations in response to a signal indicative of ambient light; means for supporting a photographic film in one of said locations, said supporting means being located in an image plane of said optical means; a solid-state image sensor disposed in the other of said locations to receive light from said optical means, said solid-state image sensor including means for generating said signal; display means for displaying an image sensed by said solid-state image sensor; and a viewfinder which includes means for viewing said object and said display means.
Claim 8
Dependent Claim
32 words
A camera, as defined in claim 5, wherein said camera is a single lens reflex camera, and said viewfinder is optically coupled to said optical means by means of a reflecting surface.
Claim 9
Dependent Claim
22 words
