摘要： A pointing device having an illumination system, an imaging array, and a controller is disclosed. The illumination system illuminates a surface over which the pointing device moves, the illumination system generating a light signal having first and second spectral regions. A portion of the light signal is viewable by a user of the pointing device. The first spectral region includes visible light of a predetermined color and the second spectral region includes infrared light. The imaging array records a plurality of images of the illuminated surface and is sensitive to light in the second spectral region. The second spectral region can be chosen to match the sensitivity of a silicon imaging array, while the first spectral region provides a decorative glow that is seen by the user.

摘要： An optical navigation device that regulates the brightness of an adjustable light source, and a method thereof, are described. Light from the light source is emitted onto a surface and reflected from the surface to a sensor. The light received by the sensor is used to measure movement of the optical navigation device relative to the surface. A light-sensitive device also receives light from the light source. The brightness of the light source can be adjusted according to the amount of light received at the light-sensitive device.
