The new HVDUO-14M 14 Megapixel Digital Colour Camera from HanVision is capable of acquiring accurate, high-resolution colour images using the Foveon ® X3 TM Pro 14M CMOS colour image sensor which incorporates the exclusive Foveon X3 colour separation technology. Unlike colour filter mosaic sensors, the Foveon X3 Pro 14M image sensor detects full colour at every pixel location.
HVDUO-14M’s 14.45 million photodetectors are arranged in a 2688 x 1792 x 3 matrix. The camera features 24/30-bit digital colour output, real-time colour processing, a parallel LVDS interface and support for all sensor scan modes, capable of single-shot or continuous acquisition. The HVDUO-14M is compatible with a wide range of standard optics and includes an automatic internal dark-frame shutter and controls for synchronised illuminators.
The HVDUO-14M suits industrial, scientific, medical, cinema and communications applications requiring high-quality colour images. Data sheet at foot of page.
Foveon 'X3‘ technology delivers sharper images, better colour detail and resistance to colour artifacts. Revolutionary Foveon X3 technology features the first and only image sensor that captures the red, green and blue light at each and every pixel location. All other image sensors record just one colour per pixel - that's why Foveon X3 technology delivers increased sharpness, better colour detail and resistance to unpredictable colour artifacts.
From point-and-shoot digital cameras to high-end professional equipment, Foveon X3 technology offers a wealth of benefits to consumers and manufacturers alike. At the same time, it paves the way for other innovations, such as new kinds of cameras that record both video and still images without compromising the image quality of either.
A direct image sensor is an image sensor that directly captures red, green, and blue light at each point in an image during a single exposure. Foveon pioneered the development of the direct image sensor using the most advanced developments in semiconductor design, image processing, and signal processing. Here is how it compares to film and typical CCD image sensors.
Film
For over 100 years, color film has traditionally been held as the gold standard for photography. It produces rich, warm tones and incredible color detail that consumers around the world have become accustomed to. Film has achieved this by using three layers of emulsion to capture full color at every point in the image.
Digital
Charged Couple Device (CCD) image sensors were developed approximately 30 years ago, ushering in the era of digital photography. Unfortunately, the rich, warm tones and detail of color film that the world came to expect from film based cameras were not achievable with the new digital cameras. This was due to the fact that CCD digital image sensors were only capable of recording just one color at each point in the captured image instead of the full range of colors at each location.
Foveon X3® direct image sensor
Finally, Foveon has combined the best of what both film and digital have to offer. This is accomplished by the innovative design of the three layer Foveon X3 direct image sensor. Similar to the layers of chemical emulsion used in color film, Foveon X3 image sensors have three layers of pixels. The layers of pixels are embedded in silicon to take advantage of the fact that red, green, and blue light penetrate silicon to different depths – forming the first and only image sensor that captures full color at every point in the captured image.
