A de-ringing device and a method thereof are provided. The de-ringing device, operative with a lookup table for storing a plurality of intensity coefficients, comprises a buffer and a de-ringing intensity determining unit. The buffer stores an input pixel sequence. The lookup table stores a plurality of intensity coefficients. The de-ringing intensity determining unit, coupled to the buffer and the lookup table, detects a plurality of pixel complexity of a first pixel group and a second pixel group associated with a target pixel in the pixel sequence, and looks up the lookup table according to the pixel complexities of the first pixel group and the second pixel group to output a de-ring intensity coefficient for the target pixel. |
