A holographic display device and method of generating a hologram using redundancy of 3D video are disclosed. A storage unit stores the hologram of a previous 3D image frame. A control unit generates an update map indicating an update required 3D point among 3D points included in a current 3D image frame based on the current 3D image frame and the previous 3D image frame and modifies the update map to further include information indicating the update of a 3D point related to the update required.

According to the present invention, a method for processing video signals is capable of determining an interview motion vector of a current block using an interview motion vector of a neighboring block. To this end, the neighboring blocks of the current block are searched and an interview motion vector candidate list can be generated.

Abstract:
A method for processing a video signal, according to the present invention, performs inter-view inter prediction for a current texture block by searching for a block coded to a reference view motion vector for neighboring blocks of the current texture block, storing a reference inter-view motion vector corresponding to the retrieved reference view motion vector of a spatial neighboring block in a candidate list, inducing an inter-view motion vector of the current texture block by using any one of the reference inter-view motion vectors stored in the candidate list, and using the induced inter-view motion vector. The present invention can improve coding efficiency by enabling a more accurate prediction of an inter-view motion vector among various inter-view motion vector candidates to thereby reduce the amount of residual data to be transmitted.
Abstract:
The present invention relates to inter-view residual prediction and is characterized by obtaining residual data of a first reference block by using a motion vector of a neighboring block, obtaining residual data of a second reference block by using a reference view motion vector or a disparity vector, obtaining a residual data prediction value by using the residual data of the first reference block and the residual data of the second reference block, and coding a current texture block by using the residual data prediction value. The present invention can perform inter-view residual prediction by using a prediction value obtained using coded data of another view point belonging to the same time band to increase the accuracy of video data prediction by using a correlation between view points and reduce the amount of residual data to be transmitted, thereby improving the coding efficiency. In addition, the complexity in a coding process may be reduced by adding a condition for applying the inter-view residual prediction.
