Abstract
The present invention relates to a method and an apparatus for coding a video signal, and more specifically, a motion vector between viewpoints is obtained by using a depth value of a depth block, which corresponds to a current texture block, and an illumination difference is compensated. By obtaining the motion vector between the viewpoints by using the depth value of the depth block, which corresponds to the current texture block, and compensating the illumination difference, the present invention can obtain an accurate prediction value of the current texture block and thus increase accuracy in inter-prediction between the viewpoints.
