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.

Calibration apparatus, calibration system, and calibration method

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 camerastoare 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 T, 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.

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 CHthrough CHaligned 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. The present invention can be applied to display devices.

A current target angle stored in a target angle register is subtracted from the immediately preceding target angle stored in a register by a subtracting device. As a result, the length (amount) and direction between the immediately preceding target angle to the current angle are generated. With the generated length and direction, a model acceleration generating circuit generates model acceleration data. With a count value of a current velocity detecting counter and a velocity data sequence that is output from a model velocity generating circuit, velocity error data is generated. With a count value of a current position detecting counter and a position data sequence that is output from a model position generating circuit, position error data is generated. The model acceleration data, the velocity error data, and the position error data are added by an adding device. The added result is supplied to a driver. The driver outputs a current that drives a pan motor.

Subtitle searching is achieved by encoding a subtitle to be displayed exclusively during a trick playback mode. Addresses for the subtitle to be played back during the trick playback mode are stored on a record medium reserved for addresses. A computer-readable memory directs a computer to retrieve these addresses and locate subtitles to be displayed during the trick playback mode on the record medium. The subtitles are searched by decoding and displaying the subtitles located at the addresses on the record medium to be displayed during the trick playback mode.
