A method of estimating a quantization parameter is provided. The method is applied to a de-blocking filter. The de-blocking filter de-blocks a decoded block-based image according to the quantization parameter, and the block-based image is coded and decoded in units of macroblocks. The method comprises calculating blocking degrees of a number of block edges corresponding to the macroblocks; and estimating the quantization parameter according to a sum of the blocking degrees.
