The next aspect to be thought over is the color depth which is also known as bit depth. The color depth is a measure of the quantity of information which can be captured on each individual pixel when scanning. You should look for higher color depth options as they decide on the scanners capabilities on determining subtle difference in colors. A good scanner should have at least 24 bit depth.
Also important is the type of sensor the scanner uses. The oldest and the most common scanner sensor is the CCD or charged coupled devices which are also present in the cameras and offer high quality images. The new technology succeeding the CCD is CIS which is Contact Image Sensor which works on with very low power consumption and enables the scanner to work on the USB port.
