Abstract:
1. An optical mouse, comprising: an optical mouse controller; and an optical mouse sensor operable to dynamically set a CPI resolution for generating an image sensing report signal indicative of a movement of the optical mouse over a surface of an object and to communicate the image sensing report signal to the optical mouse controller, wherein dynamically setting the CPI resolution includes determining a dynamic movement variable associated with the movement of the optical mouse over the surface of the object, and selecting from amongst a plurality of CPI resolutions, the selecting comprising: a) automatically selecting a high CPI resolution upon determining that the dynamic movement variable falls within a first range of predetermined variable values, and b) automatically selecting a low CPI resolution upon determining that the dynamic movement variable falls within a second range of predetermined variable values, wherein the second range is different than the first range.
