INPUT DEVICE AND IMAGE PROCESSING METHOD THERE OF

摘要

An image processing method of an input device including a scan function according to an embodiment of the present invention includes the steps of: acquiring first and second image frames and detecting coordinates of the first and second image frames; dividing an overlap area of the first and second image frames into a plurality of sub-overlap regions by using the coordinates of the first and second image frames; dividing each sub-overlap region into unit regions; setting a reference feature point among a plurality of feature points in the divided unit regions; and extracting a corresponding point by using the set reference feature point.
