High Definition Video is fast becoming the new cinema quality format. LiveLens contrast control can provide latitude and creative possibilities never before possible for this format. Eliminating the need to set up bulky and costly lighting equipment to 'fill' shadow areas of a scene by using the LiveLens can present significant production budget savings, particulary for location shooting where lighting and power supply are difficult.
For both digital and filmformat SLR cameras, LiveLens contrast control can provide latitude and creative possibilities never before possible. LiveLens can improve the technical quality of an image capture, but beyond that, the scope for creative possibilities is profound. For professional photographers and amateur enthusiasts, the LiveLens can eliminate the need to set up bulky and costly lighting equipment to 'fill' shadow areas of a scene.
The problem of ineficient or incomplete image capture caused by the contrast range in a subject exceeding the dynamic range of the CCTV camera is a considerable weakness that effects as much as 90 percent of CCTV installations worldwide.
The LiveLens lens adaptor can dramatically increase the dynamic range capabilities of any type of CCTV camera. (see Prototype Demonstration page for images)
The LiveLens lens adaptor attaches to the standard C/CS lens mounts and power supply is from the camera's standard auto iris lens supply plug. The LiveLens element does not require complex signal processing electronics to operate, providing an economical solution to contrast range problems compatible to all CCTV camera systems.
| SPECIFICATIONS | |
|---|---|
| Dynamic range expansion | 4-6* additional aperture stops latitude |
| Colour shift | zero |
| Resolution loss | zero |
| Light absorbtion | 1 aperture stop, neutral density when on. Zero when off. LiveLens element can be electrically swung out of the optical path by servo when switched off. A logic circuit receives the video signal from the camera's AI lens plug and automatically activates the servo on/off when the signal strength falls below a threshold. This maintains the camera's full night vision capabilities. |
| Installation | LiveLens attaches to the camera's standard C/CS mounts. Voltage and video signal supply from the auto iris lens plug. |
| Temperature range | 5°C to 45°C |
