The software which is called Lolux, gives the user 30, 36 and 42 db of gain, specs offered on more expensive cameras, in addition to the gain settings that ship with the camera’s standard software. LoLux is comprised of half electrical gain and half light accumulation through the shutter. The result is a clean image with few artifacts and little image noise. What is image noise, you ask?

An example of image noise. The left picture is with image noise, while the right is an improved version.
Image noise is a random, usually unwanted, fluctuation of pixel values in an image. Image noise can originate in film grain, or in electronic noise in the input device (scanner or digital camera) sensor and circuitry, or in the unavoidable shot noise of an ideal photon detector. Image noise is most apparent in image regions with low signal level, such as shadow regions or underexposed images. - Wikipedia

Although they have a 1/3-inch imager, the quality of the ProHD camcorders, such as the GY-HD250U(picture above), is getting so good that many people can’t tell the difference in terms of picture quality between it and other 1/2- and 2/3-inch cameras costing much more. Using a wide band A/D converter on the front end of the imager, the 250U allows users to get greater sensitivity than other HDV cameras. Users have reported seeing f8 at 2000 lux, which is nearly equal to what a larger-format CCD delivers.

Speaking of JVC, after months of speculation, followed by months of failed negotiations with other agencies, JVC and Kenwood have officially agreed to merge under a holding company in 2008. JVC has been under the control of Matsushita Electric Industrial Co. (trade name Panasonic) since the 1950s.
