Camera Framing Light

Camera Framing Light

 

      The Camera Framing Light is patented technology that projects the camera’s field of view into the scene as a visual reference and is ideal for digital cameras without viewfinders (ex.: hidden surveillance cameras, webcams, police body cams, home-security cameras, GoPro’s, etc.)

      Light emitting diodes surround the image sensor.  The camera is used as a projector while composing the shot.  Just prior to taking the shot, the diodes turn off and the camera’s shutter closes before opening again for the normal picture-taking sequence.

Cameras without viewfinders benefit from the Framing Light.


 

      The Framing Light is indispensable for pocket cameras and smart phones because bright sunlight typically washes out the screen.

Version 2:  The frame lines project from a micro display beside the taking lens.  Parallax errors are eliminated by using the camera’s focus distance to shift the pattern of lighted diodes to converge with the lens’ axis.

Version 3:  Framing lights can be integrated into the rim of lenses to project the horizontal and vertical fields of view.  The projected spread angle adjusts when the lens is zoomed.  

 

      The patent covers a number of versions for any format camera from a professional still or video camera, or compact digital camera and cell-phone cameras.  The Framing Light projects frame lines into the scene that match the camera’s field of view.  

      Rather than the DP and set builders losing time checking the composition in the camera monitor, they can work in the subject space seeing exactly what will be covered by the camera lens, removing light stands and adjusting props.  The Framing Light really shines when shooting a complex set, shooting through doors, into mirrors, and underwater, etc.  The Camera Framing Light provides a visual reference of the FOV regardless of the complexity of the scene or the camera angle.

Version 4:  For still and motion-picture cameras.  The Framing Light projects a camera’s field of view into the scene to eliminate the need to return to the camera viewfinder, or monitor to check composition.  The Framing Light can be used in advance of of having the camera, saving on camera-rental charges.

      Two identical Framing Lights are supplied in the rental package, and are attached to a cage frame above and beside the lens (optimized for the Arri Cage System 1).  


 

Parallax error?  (There is none):  

      In spite of the Framing Lights being displaced from the camera lens, there is zero (0) parallax error between the Framing Light and the camera lens.  The adapter plates each provide a slot and a row of attachment holes for exact X and Y positioning. 

     When a Framing Light is mounted above the lens nodal point, the projected vertical lines align exactly with the width of the horizontal lens FOV.  

     When a Framing Light is mounted beside the lens nodal point, the projected horizontal lines align exactly with the vertical lens FOV.
