Definitions

  • the present invention relates to a digital camera, and in particular to a combination of a film camera, such as a disposable camera, and a digital camera, which allows a photographic image to be taken by both cameras substantially simultaneously.
  • Digital cameras are electronic devices which are operated in a similar manner to conventional film cameras, except that the photograph is captured onto a flash memory component or other electronic memory component.
  • the digital camera When the digital camera is placed in communication with a computer, for example through a cable or infrared connection, the captured photograph can be downloaded to the computer and displayed on the computer monitor. Since the captured photograph is a digital image, it can be manipulated and stored like any other such digital image data.
  • a clear advantage of a digital camera is that it has a high memory capacity and does not require any film, so that more photographic data can be captured by such a digital camera than by a conventional camera. Also, digital camera images, once displayed on the computer, do not necessarily require any further processing, while the film of conventional cameras requires extensive processing before the images can be viewed. On the other hand, such digital cameras are more expensive than conventional cameras.
  • the present invention is of a combination of a digital camera and a film camera into a single operational unit, such that the operation of a single mechanism by the user causes a photographic image to be captured by both cameras simultaneously.

  • the present invention is of a combination of a digital camera and a film camera into a single operational unit, such that the operation of a single mechanism by the user causes a photographic image to be captured by both cameras simultaneously.
  • the combination is obtained through the provision of a special assembly featuring a digital camera, which is then added to a regular film camera, for adapting the film camera to produce the single operational unit of the present invention.
  • the photographic image is captured onto an electronic memory component of the digital camera, such as a CCD (charge-coupled device) array for example, and onto film of the conventional film camera.
  • the photographic image can then be downloaded to a computer from the memory component of the digital camera, for example in order to view the digital image on the computer monitor or other associated display screen.
  • the photographic image can be produced when the film of the film camera is developed.
  • the same or substantially similar photographic image can be reproduced in either medium from the cameras of the combined operational unit.
  • the single operational unit of the present invention provides flexibility for viewing and displaying photographic images on different image media.
  • the single operational unit of the present invention features a digital video camera attached to a film video camera. The mechanism of such a combination is similar to that for the still picture camera combination, except that such a mechanism would be adapted to the requirements for video cameras.
  • a single trigger such as a button
  • a digital still camera could be combined with a video camera to form a single operational unit according to the present invention.
  • the video camera could be a film video camera or a digital video camera, both of which are known in the art.
  • Such a combination is currently only available in a specialized, expensive single unit, while the present invention enables a single operational unit to be constructed from inexpensive components to form a much less expensive but still functional product.
  • One advantage of the present invention is that digital camera images can be quickly obtained, even at a relatively low resolution. These rapidly obtained but optionally low resolution images are then optionally used to select the high resolution, but relatively slow to develop, film camera images. Thus, without necessitating a highly expensive digital camera with high resolution, the user can enjoy the benefits of the quickly obtained digital images with the higher resolution of film camera images.
  • the principles and operation of a combination of a film camera and a digital camera according to the present invention may be better understood with reference to the drawings and the accompanying description, it being understood that these drawings are given for illustrative purposes only and are not meant to be limiting.
  • Figure 1 is an illustration of a frontal view of the combined digital camera and film camera as a single operational unit 10.
  • a film camera 12 features a film camera aperture 14 through which light is admitted in order to capture the photographic image.
  • film camera aperture 14 features a film camera lens 16 of some type which is preferably a universal focus lens, such that within a particular range of distances from film camera 12, the light is automatically focused in order to capture a focused photographic image.
  • a universal focus lens also obviates the need for separately focusing the digital camera, as described in greater detail below.
  • Film camera aperture 14 also features a film camera shutter 18 for preventing light from entering film camera aperture 14 prematurely and exposing the film, before the photographic image can be captured.
  • Film camera shutter 18 is operated by a film camera switch 20. When film camera switch 20 is depressed, film camera shutter 18 is opened for a short period of time, on the order of seconds or a fraction thereof, and light is admitted through film camera aperture 14 to capture the photographic image on the film of film camera 12 (not shown).
  • Single operational unit 10 also features a digital camera 22 as shown.
  • Digital camera 22 also features a digital camera aperture 24 with a digital camera lens 26 for focusing the light when the digital image is captured.
  • Digital camera lens 26 is preferably a universal focus lens, such that within a particular range of distances from digital camera 22, the light is automatically focused in order to capture a focused photographic image.
  • a universal focus lens also obviates the need for separately focusing the respective lenses of digital camera 22 and film camera 12.
  • digital camera aperture 24 Rather than being protected by a digital camera shutter, digital camera aperture 24 preferably is able to receive an electrical signal for commanding the electronic camera memory to capture an image. The production of this electrical signal is preferably triggered through an action of a digital camera microswitch 35, which in turn is triggered by a digital camera switch 20, as explained herein below.
  • film camera switch 20 is connected to digital camera switch 30 by a connecting bar 32. Furthermore, digital camera switch 30 is placed somewhat higher than film camera switch 20 by a block 34. Connecting bar 32 features a slot 36 through which digital camera switch 30 is connected to block 34. Digital camera switch 30 is also connected to the mechanism for operating digital camera microswitch 35.
  • film camera shutter 18 is operated simultaneously with the production of the electrical triggering signal through the action of the user when depressing film camera switch 20.
  • Figure 3 shows a back view of single operational unit 10, showing the back of digital camera 22 and film camera 12.
  • Film camera 12 features a viewing window 38 through which the user can view the area to be photographed.
  • Digital camera 22 may optionally but not necessarily feature such a window (not shown), since film camera aperture 14 and digital camera aperture 24 are arranged such that substantially the same area is photographed and substantially the same image is captured when film camera switch 20 is depressed as previously described.
  • Digital camera 22 also preferably features a screw 40 for attaching digital camera 22 to film camera 12, although alternatively a rubber gasket or other attaching mechanism may be used to attach digital camera 22 to film camera 12 (not shown).
  • Figure 4 shows a side view of single operational unit 10, showing the side of digital camera 22 and film camera 12. Again, film camera lens 16 and digital camera lens 26 are shown.
  • digital camera switch 30 is shown, raised above film camera switch 20 by block 34. Screw 40 is also shown.
  • the combined digital camera and film camera of the present invention have a number of advantages. First, both cameras capture the same or similar photographic images simultaneously through the operation of a single mechanism by the user. Second, the digital camera can then be used to preview and select photographic images for processing with the film of the film camera. Third, the film camera can be a disposable camera, such that the single operational unit can be made inexpensively. Fourth, optionally the digital camera can be prepared with a special mechanism, in order to be attached to a regular film camera which has not been specially prepared for forming the single operational unit of the present invention.
  • an adapter such as a frame, which would be attached to the digital camera.
  • the film camera would then snap into the frame.
  • the frame would feature a mechanism which is similar to the bar of the previous embodiments.
  • the digital camera is also preferably altered to capture only one image for each triggering of the electrical signal, such that each film camera image corresponds to a single digital camera image.

Abstract

La présente invention concerne une combinaison de caméra numérique (22) et de caméra à pellicule (12) en une seule unité opérationnelle (10) qui permet à l'utilisateur de faire capturer des images simultanément par les deux caméras en actionnant un mécanisme unique (20). L'image photographique est capturée sur un composant de mémoire électronique de la caméra numérique et sur la pellicule de la caméra à pellicule classique. L'image photographique peut ensuite être téléchargée sur un ordinateur depuis le composant mémoire de la caméra numérique, par exemple pour visualiser l'image numérique sur l'écran de l'ordinateur ou sur un autre écran d'affichage associé. En outre, l'image photographique peut être produite lorsque la pellicule de la caméra à pellicule est développée, ce qui permet de reproduire une image photographique identique ou sensiblement similaire sur l'un ou l'autre support à partir des caméras de l'unité opérationnelle combinée (10).
