- Digital_scan_back abstract "A scanning back is a type of digital camera back. Digital imaging devices typically use a matrix of light-sensitive photosensors, such as CCD or CMOS technologies. These sensors can be arranged in different ways, like a Bayer filter, where each row captures RGB components, or using one full-sized layer for each color, such as the Foveon X3 sensor. The main difference between both approaches is in the way the final image is constructed. In a Bayer filter, since each pixel can only record one color, the resulting pixel has to be constructed with information from its neighbouring pixels using demosaicing algorithms. Using one layer per component instead measures all color components for each pixel, so the resulting pixel is the value measured in every layer for that pixel. The downsides compared to a Bayer filter are that it is much more expensive, because N layers of sensors have to be used, and the resulting digital image is much smaller (by a factor of N). However, since the image is more accurate, more work can be done on it. A digital scan back takes a similar approach to the second type of photosensor, but instead of using one matrix for each component, it uses one array per component. This translates to a 3xN sensor matrix, where N is typically a large number (between 5,000 for earlier models and 15,000 for newer models), which is then placed vertically in a holder. To take an image, the sensor travels the x axis, taking one exposure per point.".
