Video cameras are turning up everywhere these days because they let us see something – a place, a person, an event – without being conspicuous. Camera technology is like the human eye in that it can only see objects or scenes by taking in and processing the light that is present. Just as we struggle to see clearly when the lights in a room are turned off, many video cameras must cope with low-light environments. Having a camera on the scene does not always provide the kind of insight we want unless the camera is able to overcome low-light conditions and monitor the scene clearly.
New advancements in video camera technology,specifically low-light noise filtering technology,have enhanced not only the individual still images or frames which make up a video stream but also increase the fidelity of the individual pixels that make up each frame. Operating on three dimensions, improved filtering techniques are able to remove visual anomalies in low-light video feeds and thereby clarify and sharpen the images. Cameras based on powerful real-time processors and equipped with sophisticated compression algorithms can often see better in low-light conditions than the human eye. According to the 2010 FBI Uniform Crime Report, 52.8 percent of violent crimes and 81.7 percent of property crimes remained unsolved. Cameras equipped with good low-light technology would help reduce that number.
