<P>PROBLEM TO BE SOLVED: To provide a video additional information display controller and an operation method therefor capable of displaying an image on a display unit and displaying additional information on a head-mounted display so as to disallow the additional information overlaid on the display object in the video. <P>SOLUTION: A video additional information display controller 1 determines a projection position of a display object in a video V to be projected on a head-mounted display 3, and determines a coordinate AL for additional information A so as to disallow the information to be overlaid on the projection position. The video additional information display controller 1 allows the additional information A to be displayed in an area of the head-mounted display 3 in which the video V (display unit 2) is projected, while disallowing the additional information A to be overlaid on the projection position of the display object in the video V. Thus, an inconvenience of hard-to-see caused because the additional information is overlaid on the display object in the video V can be eliminated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
