Definitions

  • This invention relates to digital photography and video cameras, specifically to a device which adds freeze-frame capability to the camcorder or video camera to which it is connected thus allowing the use of the camcorder as a digital camera.
  • Digital cameras have recently been introduced as a practical and relatively inexpensive way to import images into computers. They generate images by digitizing the output of optoelectronic transducers and temporarily storing the images in on-board memory. The images are downloaded via serial or parallel ports or other data transfer link.
  • the quality of images produced by digital cameras is generally inferior to that of optical scanners which have usually higher resolution and more accurate color rendering. Digital cameras, however, are of more practical use especially because of their portability.
  • the cost of digital cameras ranges from few hundred to several thousand dollars and is in great part determined by the quality of the opto-electronic transducers. The resolution, the image size, the number of colors reproduced varies with the quality of the camera.
  • a second way to import images into computers is to connect a video camera to a frame grabbing device connected to a computer.
  • the frame grabbing device can be internal or external and utilizes software running on the computer to acquire and store images. These devices are designed to work in conjunction with a computer and are generally not suitable for portable use.
  • digital camcorders with freeze frame capability have been introduced. They are a camcorder and a digital camera in a single unit and allow both cine and still images to be acquired. Digital camcorders are usually high-end products and still not widely used because of their cost. They are a good choice for first time buyers who can afford a more expensive camcorder but would hardly justify the cost for most people who already own a camcorder and wish to acquire still images.. In summary, the choices available today to people interested in digital photography today are:
  • the invention described here offers a fourth option which can be less expensive than purchasing a second camcorder or a digital camera and more practical that connecting a video camera to a frame grabbing device.
  • the proposed freeze frame adapter utilizes the opto-electronic transducer of the camcorder thus eliminating the most expensive element of the digital chain.
  • the freeze-frame adapter is designed as an add-on unit for camcorders.
  • the unit is always on and ready for use whenever the camcorder is on. Still images can be acquired simultaneously to video. It is not a second device to carry and set up. It has the versatility of digital cameras without the extra cost.
  • the unit does not depend on a computer to operate. It has the portability that is lacking in frame grabbers.
  • the resolution of digital images is determined in great part by the quality of the optoelectronic transducer.
  • Many camcorders have excellent transducers which can be fully utilized to generate digital images rather than purchasing an economical digital camera.
  • the embodiment of the invention presented here is construed as an add-on module which connects to the battery receptacle of the camcorder, No modifications of the camcorder or video camera are necessary.
  • the module contains both the electronics and the battery and replaces the battery of the camcorder.
  • the battery provides power to both the camcorder and the photo adapter module.
  • the snap-shot adapter is therefore not larger than the battery of the camcorder which it replaces. In an alternate embodiment the battery can be removable.
  • a short cable [2] connects the module to the Audio- Video output of the camcorder and derives the video signal used to capture the still images. The images are captured by pressing the shutter button [4].
  • the frame grabber circuitry is derived from standard electronics and therefore is not specifically described here. The same applies to the storage of images which can be realized with RAM, various magnetic storage media such as magnetic cards, disks, removable RAM etc.
  • the photo adapter module can be connected to a PC via serial or parallel ports, via infrared links or other data transfer links.
  • the video signal used as source of images for the freeze-frame adapter is derived from the camcorder via the Audio- Video output, a standard feature of most camcorders.
  • the viewfinder of the camcorder also operates as the viewfinder in snap-shot mode.
  • the image is captured by pressing the shutter button [4] Images can be acquired while the camcorder is filming. Both motion and still images of the same scene can be acquired.
  • the camcorder and the freeze frame adaptor can be operated with a single hand.
  • the shutter button [4] can be reached with the thumb of the same hand used to operate the video camera.
  • the photo adapter module represents an inexpensive and practical way to acquire still images from camcorders.
  • the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention.
  • Various other embodiments and ramifications are possible within it's scope.
  • an embodiment including separate or removable batteries is possible.
  • the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
  • Fig. 1 is a perspective view of the invention. It illustrates how the freeze frame module [1] is connected to the camcorder at the battery attachment.
  • the short cable [2] is the only other connection to the camcorder via the Audio-Video socket [3].
  • the adapter module contains the camcorder battery.
  • Fig. 2 is a schematic perspective of the invention showing the adapter module [1 ] in place. Images are acquired by pressing the shutter button [4].

Abstract

L'invention concerne un dispositif qui ajoute une fonction supplémentaire d'arrêt sur l'image aux camescopes ou caméras vidéo de manière qu'ils puissent être utilisés comme caméras numériques pour instantanés. L'adaptateur d'arrêt sur l'image est conçu comme un module à incorporer qui est relié au logement pour batterie de la caméra vidéo ou du camescope. Le module pour instantanés comprend des composants électroniques d'arrêt sur l'image et une batterie et remplace la batterie du camescope. La batterie fournit l'électricité au camescope et au module adaptateur photo. Aucune modification n'est nécessaire. Le signal vidéo utilisé comme source d'image pour l'adaptateur d'arrêt sur l'image provient de la sortie audio-vidéo du camescope. L'unité est toujours en marche et prête à être utilisée lorsque le camescope est allumé. On peut enregistrer des images fixes simultanément en vidéo. Le viseur du camescope fonctionne également comme viseur en mode instantané. L'image est capturée par pression d'un bouton obturateur sur l'adaptateur d'arrêt sur l'image. On peut enregistrer des images alors que le camescope est en train de filmer. On peut, en outre, enregistrer des images fixes ou animées simultanément. Les images enregistrées peuvent être téléchargées d'un ordinateur via un port en série ou parallèle standard ou au moyen d'une autre liaison de transfert de données.
