An edge enhancement processing unit comprising a determination block and a signal processing block is provided. The determination block determines whether the luminance of a surrounding pixel is greater than at zero level. The surrounding pixel is located around a focused pixel. The signal processing block carries out an edge enhancement process for a pixel signal generated by the focused pixel. The edge enhancement process is carried out if the determination block determines that the luminance of the surrounding pixel is greater than at zero level. |
