摘要： Disclosed are a moving picture processing method and an apparatus thereof. The moving picture processing apparatus includes a light emitting center calculator for calculating a light emitting center point for each of the sub-fields. A motion estimator detects a motion vector of a correspondent pixel using field data in a memory. A motion compensation luminance calculator calculates a motion compensation luminance for each of the sub-fields at a location of a correspondent pixel using the motion vector. An integral luminance calculator calculates a cumulative sum of predetermined luminance weights of sub-fields required to emit. A linear luminance calculator calculates a cumulative sum of predetermined luminance weights. A light emission selector determines presence/absence of light emission starting from a sub-field having the largest luminance weight, using the motion compensation luminance, integral luminance, linear luminance and luminance weight.
