Abstract:
1. A deblocking apparatus for deblocking a plurality of blocking effects on a pixel matrix defining a digital video signal, comprising: a filter, for receiving each pixel of the pixel matrix as a first target pixel of the pixel matrix to generate a first filtered pixel, wherein each pixel is associated with one of the plurality of blocking effects; a blocking detection module, detecting the blocking effect of the first target pixel according to the first target pixel and the first filtered pixel and generating a deblocking intensity factor corresponding to the first target pixel as a function of the first target pixel, such that each pixel has its own generated de-blocking intensity factor; and a blending unit, for receiving the first target pixel and the first filtered pixel, and for dynamically blending the first target pixel and the first filtered pixel according to the deblocking intensity factor to generate a first output pixel.
