Abstract

An apparatus for transmitting a multi-view stereoscopic video includes: a control unit configured to receive a group of stereoscopic images taken by a plurality of stereoscopic imaging devices; a generation unit configured to select at least one stereoscopic frame from stereoscopic frames of the received group of stereoscopic images, arrange the selected stereoscopic frames successively, and generate a multi-view stereoscopic video; an encoding unit configured to encode the generated multi-view stereoscopic video; and a transmission unit configured to transmit the encoded multi-view stereoscopic video through a transmission network.

Claims

1. An apparatus for transmitting a multi-view stereoscopic video, comprising:

a control unit configured to receive a group of stereoscopic images taken by a plurality of stereoscopic imaging devices;

a generation unit configured to select at least one stereoscopic frame from stereoscopic frames of the received group of stereoscopic images, arrange the selected stereoscopic frames successively, and generate a multi-view stereoscopic video;

an encoding unit configured to encode the generated multi-view stereoscopic video; and

a transmission unit configured to transmit the encoded multi-view stereoscopic video through a transmission network.

2. The apparatus of claim 1, further comprising an intermediate view generation unit configured to generate a group of stereoscopic images having intermediate viewpoints different from viewpoints of the plurality of stereoscopic imaging devices.

3. The apparatus of claim 1, wherein the control unit is configured to control pan, tilt, and zoom of the plurality of stereoscopic imaging devices.

4. The apparatus of claim 1, wherein the generation unit further comprises a monitoring unit configured to monitor stereoscopic frames of the received group of stereoscopic images.

5. The apparatus of claim 1, wherein the generation unit comprises an input unit configured to enable frame by frame movement in region, stereoscopic frames constituting the space on time and space axes.

6. The apparatus of claim 5, wherein the input unit is configured to select an order of arranging frames used to generate a multi-view stereoscopic video.

7. The apparatus of claim 6, wherein the generation unit further comprises a construction unit configured to arrange, according to the order of stereoscopic frames selected by the input unit, the stereoscopic frames successively.

8. The apparatus of claim 1, wherein the multi-view stereoscopic video has an order different from a time order in which the group of stereoscopic images have been taken.

9. An apparatus for receiving a multi-view stereoscopic video, comprising:

a reception unit configured to receive a multi-view stereoscopic video through a transmission network;

a decoding unit configured to decode the received multi-view stereoscopic video; and
