ABSTRACT:
The present invention provides an effective flicker detection method performing a motion compensation. The present invention includes the steps of: calculating a luminance difference between neighboring pixels; summing up the luminance difference in a specific direction if the difference is greater than a threshold value; performing a motion estimation by using a sum calculated through step (b) to thereby calculate a motion displacement; performing a motion compensation to a current frame data by using the motion displacement; calculating a difference between a previous frame data and the compensated current frame data; and detecting the flicker by using the difference calculated in step (e).
