Abstract
An image generating device and a method thereof are disclosed in the present invention. The image generating device and method may find out true motion for static text strings. The image generating device and method detect static text angles from consecutive frames and use a 3D-static text filter to recover correct motion vector fields. After our Static Text Detector fixing, the static text strings like subtitles can get more accurate motion vector and improve video quality.
