A video coding and decoding method using a weighted prediction and an apparatus for the same are provided. The video coding method includes generating a predicted image for a present block; generating a weighted prediction factor which is a scaling factor of the predicted image that minimizes the difference between the present block and the predicted image; generating a weighted prediction image by multiplying the predicted image by the weighted prediction factor; and coding a residual signal generated by subtracting the weighted prediction image from the present block. |
