`viewfinder, depending on the position of a movable
`mirror. Located in the lens of the camera is a beam
`splitter which directs a portion of the light entering the
`camera onto a solid-state image sensor. The image data
`from the sensor is written into memory, and the data
`can be retrieved from memory to drive a display lo
`cated in the viewfinder of the camera. In addition to
`producing an electronic image signal which can be used
`to verify the image recorded on film, the solid-state
`sensor is also used to perform other functions in the
`camera such as exposure control and autofocus.
`The main advantages of the camera of the present
`invention over known cameras which record electroni
`cally and on film are the improved performance and the
`reduction in size and complexity of the camera. These
`advantages are achieved as a result of integrating the
`electronic recording and the film recording functions in
`the camera. The solid-state sensor is used not only to
`capture an electronic representation of the image for
`storage and subsequent display but also to sense image
`information for use in the autofocus and exposure con
`trol mechanisms of the photographic camera.
`Other features and advantages will become apparent

`DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`With reference to FIGS. 1 and 2, there is shown a
`schematic representation of the camera of the present
`invention. As shown in these figures, a camera 10 com
`prises an imaging lens 12 having elements 14 and 16
`which are disposed along an optical axis 18. Light from
`an object propagates along axis 18 and is reflected onto
`a ground glass viewing screen 88 by a mirror 20 which
`is inclined at a 45' angle. An image on screen 88 can be
`viewed through a viewfinder 24 and a roof penta prism
`26. Viewfinder 24 includes an eyepiece 28 and a mirror
`30 which is movable between the solid line position,
`shown in FIG. 2, and the position shown therein in
`phantom. When a desired scene is framed in the view
`finder, mirror 20 is pivoted upwardly to a generally
`horizontal position (not shown) to expose the film 32.
`The exposure of the film 32 is controlled by a combina
`tion diaphragm/shutter indicated schematically at 34.
`An electronic image can be recorded in camera 10
`through the use of a solid-state image sensor 40 which
`receives light from a beam splitter 42 located along the
`optical axis 18. Light from beam splitter 42 is focused on

`
`BACKGROUND OF THE INVENTION
`1. Field of the Invention
`The present invention relates to a camera, and more
`particularly, to a camera which includes means for
`forming an image on photographic film and means for
`producing an electronic image.
`2. Description of the Prior Art
`Various cameras are known which record an image
`on photographic film and also record an image electron
`ically. Generally, these cameras include conventional
`optics and film handling mechanisms for forming an
`image on film, and they also include a solid-state imager
`and a display for forming and viewing the electronic
`image. Such a camera can be used in a preview mode in
`which a photographer can view an electronically
`recorded scene on the display without having to expose
`the film. The preview mode makes it convenient to
`arrange the composition and verify the exposure level
`before a permanent image is captured on film. The cam
`era can also operate in a review mode in which the
`photographer can view an image on the display which
`has also been captured on film. An important benefit of 25
`the review mode is that it adds the capability to evaluate
`pictures before leaving a scene, including the evaluation
`of such photographic variables as composition, flash
`synchronization, camera and subject motion, exposure
`level, and depth of field. This review capability is of 30
`particular value for functions, such as weddings, where
`it is important to know that a certain scene has been
`properly recorded.
`U.S. Pat. No. 4,742,369, discloses an electronic still
`camera which is adapted to form an image on a photo
`35
`sensitive film and on a solid-state imaging element in
`response to the actuation of a shutter switch. The cam
`era can form the images on the film and sensor simulta
`neously or in sequence. The camera elements for form
`ing the image on the photosensitive film are conven
`tional camera elements found in a single lens reflex
`camera. The shutter speed and desired lens aperture are
`manually controlled by the operator. A beam splitter in
`the camera directs light from the optical system to a
`solid-state imager. A disadvantage of the camera shown
`45
`in this patent, as well as other known prior-art cameras,
`is that the camera includes essentially two different
`systems to record the electronic image and to control
`the recording of the photographic image. This arrange
`ment makes the camera complex and expensive to man
`50
`ufacture.
`SUMMARY OF THE INVENTION
`It is an object of the present invention to overcome
`the problems in the prior art described above and to
`55
`provide an improved camera which is particularly suit
`able for recording an image on photosensitive film and
`on an electronic device.
`In accordance with one aspect of the present inven
`tion, there is provided a camera comprising means for
`forming an image on photographic film; and means for
`producing an electronic image signal, the producing
`means including means for sensing scene parameters
`and for controlling the forming means in accordance
`with values of the parameters.

`In one embodiment of the present invention, a camera
`of the single lens reflex type includes an optical means
`for directing an image onto photographic film or into a
