1. A mobile scanner comprising:

  • an image sensing module comprising;

    a one-dimensional image sensor array;

    a lens mounted in front of the image sensor array; and

    a first illumination source comprising three colored lights that are turned on independently and successively by an illumination control signal;

    a motion mechanism working in synchronization with the image sensing module, the motion mechanism causing a scanning document illuminated by the first illumination source to pass through the lens so that the scanning document is imaged by the image sensor array; and

    an interface module coupling the image sensing module and the motion mechanism to a computing device and receiving a power supply and system control signals from the computing device;

    the image sensing module and the motion mechanism receiving the power supply and illumination control signals from the interface module to operate.
