Abstract: A multi-source filter based on H.264 de-blocking includes the following units. A quantization parameter (qP) calculation unit receives an image data and calculates a qP. A boundary strength (bS) calculation unit receive the image data and calculates a bS. A block detector receives the image data and determines whether the image data falls in the block boundary. An image edge detector receives the image data and determines whether it is not belonged to an image edge region. An enabling unit receives the qP to determine whether to enable a de-blocking filtering operation. A determining unit filters the image data to output a new image data when determines that the image edge is not at the block boundary and the filtering operation is required.

Abstract: The present invention discloses a compensation hardware device for non-uniform regions in a flat panel display. The hardware device processes the flat panel display having non-uniform regions through digital signal processing, instead of by using materials, optical films or fabrication processes. Therefore, the manufacturing cost and complexity of the flat panel display are not negatively affected. In the digital signal processing architecture, a non-uniform-region compensation unit is used to process a video signal falling in a non-uniform region pixel, such that the non-uniform regions may not negatively affect the video signal displayed on the panel.
