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 multiview images so as to achieve improved accuracy in inter-view inter prediction.
