A method for tracking a position of an optical computer mouse based on determining a spatial displacement between image frames. A respective image frame is considered as an anchor frame if the respective image frame comes first in a sequence of image frames or the distance of the respective image frame to its immediately previous anchor frame is equal to or greater than a displacement threshold, and the respective image is considered as an intermediate frame if its distance to its immediately previous anchor frame is below the displacement threshold. Only anchor frames are stored in memory and used for future displacement measurements between image frames captured by the mouse.
