Latest Patents

One of his latest patents is titled "Method and apparatus for de-interlacing video data." This invention provides a method and apparatus for de-interlacing video data by utilizing a horizontal motion vector of a horizontal motion between fields. The process compensates for the horizontal motion regarding a target pixel of a frame if the horizontal motion vector is found to be substantially not null. This results in an upgraded quality of image after the de-interlacing process. Another significant patent is the "Interpolation method for image pictures and image processing apparatus thereof." This method is applied to image pictures for interpolating at least one pixel into a position to be interpolated in a target image frame. It includes receiving a plurality of image fields, estimating the motion speed of the image object, and determining the pixel from the plurality of image fields according to the motion speed.
