Patent Images

1. A device for displaying an image having first and second image portions in response to an image signal, comprising:

  • a first light source responsive to a first input signal to emit a first modulated light beam along a first light path relative to the first light source;

    a scanner having an input positioned along the first light path, the scanner being operative to receive the first modulated light beam and to redirect the first modulated light beam through a selected scan path toward a first image region in which the first modulated light beam defines a first image portion; and

    electronic control circuitry having an input port for receiving the image signal and a first output coupled to the first light source, the control circuitry being responsive to the image signal to produce the first input signals, the control circuit further including;

    an error circuit responsive to a determined error in the first modulated beam intensity to produce an error signal;

    a correction circuit having an input coupled to the error circuit, the correction circuit being responsive to the error signal to adjust the first input signal to reduce the determined error.
