Simplification of a preparation step of a cell population used for the treatment of ischemic diseases, and provision of a cell population that shows more effective treatment are shown. A method of producing a cell population wherein a vascular endothelial progenitor cell and/or an anti-inflammatory macrophage are/is enriched, including cultivating a mononuclear cell derived from bone marrow, cord blood or peripheral blood in a serum-free medium containing stem cell factor, interleukin-6, FMS-like tyrosine kinase 3 ligand, thrombopoietin and vascular endothelial cell growth factor, and proliferating vascular endothelial progenitor cell from the cell; and a cell population obtained by the method are shown.

Method for in vitro proliferation of cell population containing cells suitable for treatment of ischemic disease

A video combining apparatus to superimpose a virtual image such a CG image on a video image of the real world or on a see-through type display device. An area in which the virtual image is not to be displayed can be easily designated by a user. If the user holds a frame with markers in his/her sight, the frame is image-sensed in the video image of the real world. The area designated by the user is detected by detecting the position of the marker in the video image, and the virtual image is not superimposed in this area.

Video combining apparatus and method

A system is provided for obtaining parameters about the position and orientation of a camera, where the camera has a fixed position and orientation, by using the image coordinates and world coordinates of markers included in an image photographed by the camera. This system uses a live-image display mode for successively obtaining images input to the camera and a still-image display mode for obtaining an image input to the camera at predetermined time. The markers can be extracted by using the image obtained in either mode. The system can select either automatic-extraction mode or manual-extraction mode for extracting the marker in live images, so that the markers can be extracted with a high degree of accuracy under all conditions to obtain the position and orientation parameters of the camera.
