Provided is a projection system that sets an arbitrary three-dimensional shape as a projection target and properly corrects geometric distortion of a projected image even when a user's viewpoint is not fixed. A projection unit of the projector apparatus projects a test image for first adjustment. A three-dimensional shape measurement unit measures the three-dimensional shape of the projection target. An image capturing apparatus captures the test image for first adjustment projected by the projection unit to obtain a captured image for first adjustment. A projected image adjustment unit (1) performs first adjustment processing for correcting an image such that geometric image distortion viewed from an imaging point, at which the captured image for first adjustment has been captured, is reduced, based on a captured image for first adjustment obtained by the image capturing apparatus, and (2) performs second adjustment processing for correcting the image such that the geometric image distortion is reduced based on a state in which the image adjusted by the first adjustment processing is projected by the projection unit.

Methods, devices, and computer programs for augmenting a virtual reality scene with real world content are provided. One example method includes an operation for obtaining sensor data from an HMD of a user to determine that a criteria is met to overlay one or more real world objects into the virtual reality scene to provide an augmented virtual reality scene. In certain examples, the criteria corresponds to predetermined indicators suggestive of disorientation of a user when wearing the HMD and being presented a virtual reality scene. In certain other examples, the one or more real world objects are selected based on their effectiveness at reorienting a disoriented user.

Videos are to be displayed in parallel, without missing information or a decrease in efficiency in the usable display region.

The aspect ratio of the large screen of an information processing apparatus 100 is 16:9, which is compatible with a Hi-Vision video. In a case where the large screen is used in a portrait layout, if the large screen is divided into three small screens in the vertical direction, the aspect ratio of the small screens after the dividing is 9:16/3=16:9.48. With respect to the original video content at 16:9, the ratio in inches is 9/16=56.25% (the area ratio is (9/16).sup.2=31.64%). Accordingly, the usable display region can be efficiently used.

A virtual object display system includes a plurality of head-mounted displays 1 each having a virtual object acquisition unit 22 that acquires a virtual object, a display information acquisition unit 23 that acquires display information used to display the virtual object, and a display control unit 24 that causes a display unit to display the virtual object on the basis of the display information, and enables switching between of first display control for causing the virtual object to be displayed on the basis of display information acquired by each of the plurality of head-mounted displays 1 and second display control for causing the virtual object having an identical orientation to an orientation of the virtual object displayed on the basis of display information acquired by another head-mounted display 1 to be displayed.

A graphics processing system comprises at least one memory device storing a plurality of pixel command threads and a plurality of vertex command threads. An arbiter coupled to the at least one memory device is provided that selects a pixel command thread from the plurality of pixel command threads and a vertex command thread from the plurality of vertex command threads. The arbiter further selects a command thread from the previously selected pixel command thread and the vertex command thread, which command thread is provided to a command processing engine capable of processing pixel command threads and vertex command threads.

Systems and method for image generation in a gaze tracking display. A gaze tracking display system includes a graphics processor and display circuitry. The graphics processor is configured to perform foveated rendering of image data, and to output foveated image data. The display circuitry is coupled to the graphics processor. The display circuitry includes a display device and a display controller. The display device is configured to produce a viewable image. The display controller is configured to drive the display device. The display controller includes foveated data reconstruction circuitry configured to produce an image at a resolution of the display device based on the foveated image data received from the graphics processor.

The present technique relates to an information processing apparatus, an information processing method, a program, and a moving body that can appropriately display content on top of a scene viewed by a user.

An aspect of the present technique provides an information processing apparatus that sets a frame as a superimposition location of content in a region corresponding to a surface of an object on the basis of a movement state of a user and generates visual information for displaying the content in the region corresponding to the set frame. The present technique can be applied to an apparatus that performs AR display of content.

A display apparatus according to an embodiment of the present technology includes a display unit, a motion sensor, a region setting unit, and an information generating unit. The display unit includes a tubular display whose directional range in which an image is displayed is larger than 180 degrees. The motion sensor detects an observer who observes the display. The region setting unit sets a first region visible from the observer and a second region different from the first region as regions on the display on the basis of a detection result of the motion sensor. The information generating unit generates main information displayed in the first region and illumination information regarding illumination light presented in accordance with the second region.

A display control device includes: a photodetection sensor configured to detect light from pixels of display screens with both a first display device and a second display device with a pixel size different from that of the first display device in a display system in which a video signal is displayed on a plurality of display devices adjacent to each other as detection targets; and a display adjustor configured to determine a degree of enlargement or reduction of video signals displayed on the display devices on the basis of a difference between the pixel size of the first display device and the pixel size of the second display device based on a result of detection from the photodetection sensor.

A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.
