Abstract:
A mixed reality presentation apparatus for presenting a mixed reality to an observer by superimposing a virtual space image including a virtual object image on a real space image visually identified by the observer and presenting the virtual space image to the observer, comprising:real space image capturing means for capturing a real space image; detecting means for detecting viewpoint information of said observer; virtual image generating means for generating a virtual space image based on the viewpoint information; and superimposing means for superimposing the virtual space image on the real space image, wherein said virtual image generating means includes: region determination means for determining a boundary box region that surrounds virtual text information generated as the virtual space image; tone detection means for detecting an average tone within the boundary box region in the real space image; calculating means for calculating the complementary color of the average tone as a calculated tone; and drawing means for drawing the virtual text information using the calculated tone.
