Abstract: In a calibration apparatus, a captured image acquisition unit acquires data of an image of a calibration chart captured by a fish-eye imaging apparatus. A distortion correction unit makes an assumption of a parameter of the imaging apparatus, takes into account a projection system to make a correction, and adjusts the parameter until an image of the original chart is obtained. A pseudo image drawing unit uses model data of a chart to draw a pseudo captured image. A point-of-view adjustment unit compares the pseudo image and the captured image and adjusts a point-of-view position of a virtual camera according to a difference between positions of markers or intervals of patterns to specify a position of the imaging apparatus.

Abstract: To provide an excellent photographing apparatus including a plurality of cameras and capable of photographing a wide angle image with less parallax. View point positions (camera positions) of video cameras 101 to 106 are radially arranged at predetermined angular intervals on a horizontal concentric circle about a vertical reference axis that passes a predetermined reference point. The video cameras are fixed in such a manner that camera principal-axis directions of the video cameras are individually directed outward and upward from a horizontal plane by a predetermined elevation angle Tvu, with the result that upper end portions of a vertical angle of view overlap. Therefore, photographing can be performed uninterruptedly even in an overhead direction without providing a camera that is directed right above.

Abstract: The present technique relates to a display device and method, and a program for presenting high-quality stereoscopic images in a simpler manner. A display unit is a four-viewpoint display device having a parallax barrier. On the display unit, block regions that are formed with pixels of channels CH0 through CH3 aligned in the parallax direction are aligned in the parallax direction. An allocation control unit allocates a parallax image for the left eye or a parallax image for the right eye to the pixels of each channel in block regions, in accordance with the viewpoint position of the user. For example, the same parallax image is allocated to pixels of two different channels adjacent to each other in the parallax direction. A generating unit generates a combined image by combining the parallax image for the right eye and the parallax image for the left eye in accordance with the allocation performed by the allocation control unit, and causes the display unit to stereoscopically display the combined image.

An imaging apparatus 11 images multiple imaged images P(1) through P(N) in a state turning with a turning center C11 as the center. The imaging apparatus 11 trims from each of the obtained multiple imaged images a region determined by a predetermined reference position in the imaged image as a strip-of-paper image, and arrays and synthesizes these strip-of-paper images, thereby generating a panorama image with a predetermined region on imaging space as a subject.

According to this panorama moving image, a subject in an imaged image can be displayed with motion. The present invention can be applied to cameras.
