  • Publication number: 20120113226
    Abstract: A 3D imaging device is provided that includes an identification unit, a parallax information decision unit, a display position decision unit, and a 3D display control unit. The identification unit calculates parallax information with respect to an object image based on a first image signal and a second image signal. The identification unit also sets identification information for identifying an object image. The identification unit further outputs first parallax information and identification information. The parallax information decision unit decides on second parallax information based on first parallax information so that identification information is visually recognizable at a depth separate from the object image. The 3D display control unit is coupled to at least one of the identification unit, the parallax information decision unit, and the display position decision unit.
