MOTION ESTIMATION APPARATUS AND METHOD USING PREDICTION ALGORITHM BETWEEN MACROBLOCKS |
摘要 |
Disclosed is a motion estimation apparatus and method using a prediction algorithm between macroblocks. In the motion estimation method, an average of a motion vector of a macroblock 1 and a motion vector of a macroblock 3 is determined as a prediction motion vector. A prediction sum of absolute difference (SAD) value of the macroblock 2 is calculated, which is an SAD value based on the prediction motion vector. A reference SAD value for neighboring macroblocks of the macroblock 2 is compared with a value obtained by subtracting a predetermined threshold value from the prediction SAD value. Normal motion vector estimation is performed on the macroblock 2 based on the compared result.
