    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.

    Abstract: The present invention relates to a method and apparatus for processing a video signal, which involve acquiring the prediction value for the current texture block and performing an inter-view compensation on the prediction value for the current texture block using a first compensation coefficient and a second compensation coefficient. The first compensation coefficient is acquired using the neighboring pixel of the current texture block and the neighboring pixel of a reference block. The second compensation coefficient is acquired using the neighboring pixel of the current texture block, the neighboring pixel of the reference block, and the first compensation coefficient. The method and apparatus of the present invention compensate for inter-view differences caused by imaging conditions, such as lighting or a camera, during the capture of multi-view images so as to achieve improved accuracy in inter-view inter-prediction.
