Abstract
A method capable of estimating multi-degree-of-freedom motion of an optical sensing apparatus includes: providing an image sensor having a pixel array having a plurality of image zones to sense and capture a frame; providing and using a lens to vary optical magnifications of a plurality of portion images of the frame to generate a plurality of reconstructed images with different of field of views, the portion images of the frame respectively corresponding to the image zones; and estimating and obtaining a motion result for each of the reconstructed images to estimate the multi-degree-of-freedom motion of the optical sensing apparatus.
