Abstract
There is provided an optical navigation device including an image sensor, a processing unit, a storage unit and an output unit. The image sensor is configured to successively capture images. The processing unit is configured to calculate a current displacement according to the images and to compare the current displacement or an accumulated displacement with a threshold so as to determine an outputted displacement. The storage unit is configured to save the accumulated displacement. The output unit is configured to output the outputted displacement with a report rate.
