<P>PROBLEM TO BE SOLVED: To provide an imaging projection system decreased in aberration despite a simple configuration and able to observe an image with the feeling of presence without making the picked-up image of a camera itself conspicuous. <P>SOLUTION: The imaging projection system comprises; an imaging device including an imaging part and a first reflection curved surface; and a projecting device 2 including a projecting part 21, a second reflection curved surface 22, and a curved screen 23. The eccentric position of the first reflection curved surface relative to the imaging part is similar to the eccentric position of the second reflection curved surface 22 relative to the projecting part 21. A plane including a central principal ray of a luminous flux traveling toward the screen 23 from the projecting part 21 is assumed as a YZ cross-section, and a plane including the perpendicular of the screen 23 at the projection center orthogonal to the YZ cross-section and having the intersection of the central principal ray and the screen 23 and at the projection center is assumed as an XZ cross-section. The recessed surface of the screen 23 is oriented toward the second reflection curved surface 22 within the XZ cross-section and the projecting surface of the second reflection curved surface 22 is oriented toward the screen 23 within a plane parallel to the XZ cross-section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
