Kane Computing has become the UK Distributor for the DeltaVu range of high-resolution USB microscope cameras, invented and manufactured by DeltaPix.
DeltaVu, a revolutionary new technology invented by DeltaPix in Denmark (patent pending), represents a breakthrough in sub-pixel shifting technology resulting in increased image resolution and precise colour.
The only practical limitation on the resolving power of digital cameras using DeltaVu technology is the limitation of the optics being used.
In theory, DeltaVu technology can resolve infinite detail.
The first product featuring this pioneering technology is the Infinity XT high resolution USB microscope camera.
21Mpixel resolution is achieved through shifting the 1280 x 1024 pixel array of a half-inch colour sensor.
Users will have the flexibility of choosing between 1.3, 5, 12 and 21Mpixel resolution taking full advantage of their research microscope optics to capture precise detail.
With DeltaVu technology each pixel is calculated for all three primary colours (red, green and blue) for precise colour reproduction.
DeltaVu technology is designed to work around the limitation caused by the increased fill factor of newer generation image sensors while at the same time providing even more correct colour than "real colour".
Through its ability to capture and interpret details, which are much smaller than the size of a single pixel, DeltaVu dramatically increases both spatial resolution and colour quality.
The way this is achieved is by moving the sensor a fraction of a pixel between each image capture.
The result is a large amount of overlap between neighbouring pixels for each image captured.
Knowing the precise location of each sub-pixel shift and using patent-pending software algorithms, which intelligently calculate the differences between pixels, images containing astonishing detail and enhanced colour clarity are achieved.
With this technique, objects much smaller than the size of an individual pixel can be resolved with no interpolation artefacts.
In theory, by adjusting the amount of pixel overlap, the resolving power can be increased without limit.
In practice, however, the resolution is restricted by the resolving power of the optical system.
