Abstract
A method for performing fixed-pattern noise (FPN) estimation in an optical mouse includes: capturing a series of images to generate a plurality of frames; accumulating motion of the optical mouse to generate an accumulated distance; comparing the accumulated distance to a threshold; when the accumulated distance is greater than the threshold, enabling FPN estimation of the plurality of frames; and resetting the accumulated distance to zero.
