Abstract

A method for making a lower frame rate of an optical navigation sensor mimic a higher frame rate of the optical navigation sensor includes: receiving a motion delta of the optical navigation sensor at the lower frame rate; dividing the motion delta into a smaller number of parts; dividing a time period of the lower frame rate to generate a time threshold which is shorter than the time period of the lower frame rate; receiving a clock signal for updating a counter; and outputting a first part of the delta when the counter reaches the time threshold.
