The term megapixel comes from the field of digital photography and describes the sum of the available image points (pixels) on a sensor. A megapixel stands for 1 million pixels. Basically, it can be said that a high number of megapixels also stands for a higher resolution of the images or scans. However, you have to note that several factors naturally have an influence on both the quality and the resolution. For example, appropriate lenses are necessary in order to be able to bring the quality to the sensor through the optics. It must also be taken into account that the resolution of the scan or the image always depends on the distance between the lens and the original as well as on the focal length, pixel size and the relationship between the sensor format and the original format. Commercially available consumer cameras usually have a possible resolution of 20-30 megapixels.
For our scan systems we only use our in-house developed and produced X71 camera. As the name suggests, this is a camera with a 71 million pixels sensor. In addition, the camera is equipped with a special lens and designed for the highest demands of scanning documents.
