NHK intorduces Ultra HD Imaging System Using Single 33Mpix CMOS Sensor
NHK Science & Technology Research Laboratories is conducting research on creation of a compact Ultra High Definition camera, and displayed a small 33 megapixel trial imaging device at its Technology Open House 2011.
“Our primary goal in making this single-chip imaging equipment was to make a camera small enough to be practical to use when filming outside. The difference from other products is that it uses a single sensor to achieve the full Ultra High Definition resolution of 33 million pixels. By using color filter technology that is used in digital cameras equipped with Bayer masks, and dividing color by fields to get information, it is possible to achieve a very compact camera.”
Until now there has not been a single sensor capable of imaging the full resolution of 33 million pixels, so they used a system of 4 chips each capable of imaging 8 million pixels. Since this trial single-chip imaging equipment has the same number of elements and signal format as the current 4-chip imaging systems, it can be used as it is in UHD equipment developed to date.
“This captures images the same way as ordinary digital cameras, with a sensor right behind the lens. This actually has a lens that is used in digital cameras. You can freely choose from among existing lenses, and can attach lenses that are not specially designed.”
“This is still a hand-built trial device, and we want to work with a manufacturer to finalize it and make a product for actual use.”
