Abstract
A navigation device having a small navigation sensor pixel array capable of ultra high speed imaging is proposed. A first image and a second image of a plurality of images are selected according to a predetermined difference between the corresponding acquisition times of the first image and the second image. The first image and the second image are compared to determine an amount of overlap between the first image and the second image. The predetermined difference is adjusted for subsequent image comparisons according to the amount of overlap between the first image and the second image.
