PROBLEM TO BE SOLVED: To easily optimize display of a large screen video using a video projector in accordance with a position and a direction of a viewer.SOLUTION: A video processing device 1 comprises a sensor portion 11, a condition recognizing portion 12, a correction parameter generating portion 13 and video correcting portions 14 and 15. The sensor portion 11 acquires a position and a direction of a viewer. The condition recognizing portion 12 determines the sizes of regions, on which videos from projecting portions 16 and 17 are displayed, in a screen 18, on the basis of the respective positions and direction of the projecting portions 16 and 17 and the position and the direction of the viewer acquired by the sensor portion 11. The correction parameter generating portion 13 determines a conversion parameter for correcting the videos projected from the projecting portions 16 and 17, on the basis of the sizes of the regions determined by the condition recognizing portion 12. The video correcting portions 14 and 15 perform conversion processing to an input video SIG2 using the conversion parameter determined by the correction parameter generating portion 13.SELECTED DRAWING: Figure 1 |
