9.What is "STAT LIGHT" camera?
The "Star Light" series of CCD video cameras is one of the many unique lines of cameras that MINTRON has developed for special-purpose applications. By incorporating frame integration technology, Star Light cameras offer an unsurpassed level of low-light performance, allowing image formation in near total darkness.
In these cameras, photons are accumulated by the CCD for periods 2 to 128 times longer (1-2 seconds) than normal maximum exposure times for video CCD cameras (1/60 or 1/50 second). As a result, the minimum illumination needed by the camera to produce an usable image is decreased by a factor of 2 to 128 times.
Using our Star Light cameras with frame integration technology, users can see color images under starlight
¡@illumination conditions (0.0035 Lux) and black&white images under cloudy starlight conditions (0.0002 Lux). The scattered background light prevalent in cities (i.e. light pollution) is adequate for good colour exposures.Star Light cameras can also extend the effective range of supplementary infrared illumination used to generate "night-time" images. Using frame integration exposures, the effective range of an infrared source can be extended 128 times - so, for example, an infrared projection lamp designed to illuminate an area 10 m. away will have its range extended to 1280 m. immediately if using a Star Light camera.
The maximum exposure (frame integration rate) is fixed at four times (4x) for the "F" series models (63F0/ 63F1/62F1) and 64 times (64x) for the 6318/ 6368/ 6268 models. The "V" series models (63V0/63V1/62V1) are capable of 2 ~128 times (2x -128x) frame integration periods, programmable by the user through an on-screen display (OSD) menu. The frame integration exposure capability of the "V" series cameras can be further extended to 256x; 512x; or 1024x (or more) by special order. Note that these special extended exposure times also require a special cooling system to bring the CCD chip temperature down to -10C to decrease the dark current and prevent "pixelation."
