Abstract
Methods of sampling a surface having a micro-texture upon which an optical navigation circuit tracks movement. An embodiment of the method comprises determining a rate for taking samples of the surface, determining an exposure level of the surface, illuminating the surface at the determined rate for taking samples, and illuminating the surface for each of the samples with pulses of light at the determined exposure level.
Claims7
A method of sampling a surface having a micro-texture upon which an optical navigation circuit tracks movement, the method comprising:
- determining a rate for taking samples on the surface;
- determining an exposure level on the surface;
- illuminating the surface at the determined rate for taking samples;
- and
- illuminating the surface for each of the samples with pulses of light at the determined exposure level.
A method of sampling a surface having a micro-texture for tracking movement with an optical navigation circuit, the method comprising:
- determining a sampling rate based upon the micro-texture of the surface;
- determining an exposure level based upon the micro-texture of the surface;
- and
- pulsing light onto the micro-texture of the surface at the determined exposure level and the determined sampling rate.
