Abstract
A deblocking apparatus is provided. The deblocking apparatus includes a filter, a blocking detection module and a blending unit. The filter receives a target pixel of a pixel matrix to generate a filtered target pixel. The blocking detection module generates a deblocking intensity factor according to the pixel matrix. The blending unit receives the target pixel and the filtered target pixel, and dynamically blends the target pixel and the filtered target pixel to output an output pixel according to the deblocking intensity factor.
