摘要： There is provided an image processing apparatus for describing a real image as a virtual object using space data formed based on a photo image of the real object, and generating a virtual image of the virtual object using the space data. The image processing apparatus captures the photo image of the real object from a real camera viewpoint position while illuminating the real object by an illumination light source placed at a real illumination position. The captured photo image is converted into space data in the form of an object for each pixel, and the space data is stored in a memory together with various illumination conditions at the real illumination position to allow a search at a later time.

摘要： An OCT apparatus that photographs with a plurality of measuring beams concurrently, has a mechanism for adjusting the optical path length of a reference beam for each measuring beam. Accordingly, when tomographic images photographed in this manner are displayed side by side, because the depth of photographing varies from one tomographic image to another, it is difficult for an operator to comprehend the positional relation between the photographed images. In displaying tomographic images acquired with a plurality of measuring beams, the display position of each tomographic image is adjusted based on the changed optical path length of a reference beam of the measuring beam used for the image. The tomographic images are thus aligned in height and are presented in a manner that is easy for the operator to comprehend the positional relation between the photographed images.

摘要： A shadow body generation unit generates a shadow model defined by a limited number of lines extending from a position of a light source to an outline of a hand. If the virtual object is partially or fully included in the shadow model and a position of the virtual object is further away from the position of the light source, the shadow body generation unit generates a shadow for a partially obscured area included in the shadow model.
