Method and Apparatus for Determing Encoding Mode by Using Temporal and Spartial Complexity

The present invention relates to an encoding mode decision method using temporal and spatial complexities and device. The present invention relates to a device for determining a coding mode, the temporal complexity calculation for calculating a temporal complexity of a macroblock unit; And a mode determination unit determining an encoding mode using the temporal complexity provides an encoding mode decision apparatus using a temporal complexity comprising parts. According to the present invention, not only it can more accurately calculate the temporal and spatial complexities of a macroblock as rates by selecting an optimal coding mode by him - the processing speed to reduce the complexity of the calculations at the time of applying a distortion optimization It can be improved.
