1. A dental observation device, comprising:
a camera performing image capturing of a left parallax image and a right parallax image of a desired image-capturing site in an oral cavity region;
a direction detector detecting an image-capturing direction of the camera for the image-capturing site;
a storage storing three-dimensional image information on the oral cavity region acquired by CT imaging in advance;
a processor generating a three dimensional captured image by processing the left and right parallax image captured by the camera, and the processor also generating a planar display converted image corresponding to the desired image-capturing site by converting the stored three-dimensional image information into two-dimensional sectional image; and
a display displaying, side by side, the three dimensional captured image and the planar display converted image;
wherein the three-dimensional captured image of the image-capturing site is displayed three-dimensionally,
the planar display converted image is displayed two-dimensionally,
both being viewed in a direction parallel to the image-capturing direction,
a cross section of the planar display converted image is set perpendicular to the image-capturing direction, and
the planar display converted image being viewed at the same angle around the image-capturing direction as that of the three-dimensional captured image; and
wherein when the image-capturing direction is changed, the cross section of the planar display converted image remains perpendicular to the image-capturing direction.
