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. |
