Patent ID: 7750897

Claim:
A video processing apparatus for a display device comprising: edge detection means for receiving input video data and for detecting a subset of pixels in the input video data corresponding to an edge of an object, the object being associated with pixels in the input video data, and the object being included in both reference video data corresponding to a previous frame or field, and the input video data, the input video data corresponding to a current frame or field, the reference video data being for display before the input video data; motion detection means for receiving a detection result from the edge detection means and for detecting motion of the edge of the object by comparing the input video data with the reference video data, and for detecting a speed of the object, the motion detection being limited to the detected subset of pixels corresponding to the edge of the object; display means for displaying the input video data, the display means comprising a plurality of display units; first video processing means for processing the subset of pixel values for the motion detected subset of pixels corresponding to the edge of the object based on a combination of the detected motion of the object and time response characteristics of the display units comprising the display means; and second video processing means for processing pixel values for pixels in the input video data other than the motion detected subset of pixels corresponding to the edge of the object and processed by the first video processing means, thereby limiting the pixel values processed by the second video processing means to non-motion detected pixels in the input data; wherein the display means displays the processed input video data at pixel intensities corresponding to the pixel values processed by the first video processing means and the second video processing means, wherein the first video processing means comprises: a correction means for receiving a value corresponding to the speed of the edge of the object and for correcting the pixel values for the motion detected subset of pixels based on a gain related to the received speed of the object, a value corresponding to the time response characteristics of the display units, and a difference value calculated by the edge detection means corresponding to the pixel intensities.
