Optical sensing apparatus to navigate position and a navigation method thereof |
摘要 |
An optical sensing apparatus and method includes calculating an accurate motion vector coordinate value of a current preprocessed image by partial-searching a particular coordinate axis corresponding to a predetermined direction determining coefficient, a predetermined speed determining coefficient, and/or a predetermined direction and/or speed determining coefficient according to a history of a motion vector coordinate values with respect to a past preprocessed image, calculating the motion vector coordinate value of a future according to a history of a motion vector coordinate value of the current preprocessed image, and performing a position navigation with respect to current or future preprocessed image.
