  • System and method for reducing jitter during an optical navigation operation
    Patent number: 8022984
    Abstract: A system and method for reducing jitter during an optical navigation operation operates to automatically switch the current resolution based on jitter-resolution correlation data.
    Type: Grant

  • Programmable resolution for optical pointing device
    Patent number: 7889178
    Abstract: A pointing device, such as an optical mouse, includes a light unit for illuminating a surface, a photodetector array configured to generate image information related to the illuminated surface, a navigation engine for generating navigation information at a target resolution of the pointing device, and a resolution input interface for controlling or adjusting the target resolution value of the pointing device via input of a resolution scaling ratio. The resolution input interface is configured for user input of the resolution scaling ratio, such that the target resolution of the pointing device can be readily adjusted, in real time, over a broad range of resolution values and in small increments. A technique for mitigating cursor jitter problems at high resolution values is also disclosed.
