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 head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

An information processing device (1) according to an embodiment includes a display control unit (34) and a decision unit (31). The display control unit (34) displays a content image on a head-mounted display. During display of the content image by the display control unit (34), the decision unit (31) decides whether or not a surrounding person exists in a front direction of the head-mounted display on the basis of a camera image obtained by capturing an image of a surrounding environment of the head-mounted display. In a case where the decision unit (31) decides that a surrounding person exists, the display control unit (34) moves a display position of the content image.

An information processing device according to an embodiment includes a control unit that performs: control of switching a display coordinate system of display content from a first display coordinate system to a second display coordinate system, the display content displayed on a surface of a real object by a display unit, depending on a state of an input operation of changing a position or an angle of the display content; and control of changing a display position or a display angle of the display content in accordance with the second display coordinate system and causing the display unit to display input assist display corresponding to axes of the second display coordinate system in a case where the display coordinate system is switched from the first display coordinate system to the second display coordinate system.

In one embodiment, a computing system may store, in a memory unit, a first array of pixel values to represent a scene as viewed along a first viewing direction. The first array of pixel values may correspond to a number of positions uniformly distributed in an angle space. The system may determine an angular displacement from the first viewing direction to a second viewing direction. The system may determine a second array of pixel values to represent the scene as viewed along the second viewing direction by: (1) shifting a portion of the first array of pixel values in the memory unit based on the angular displacement, or (2) reading a portion of the first array of pixel values from the memory unit using an address offset determined based on the angular displacement. The system may output the second array of pixel values to a display.

A vehicular display control device including: memory; and a processor coupled to the memory, wherein the processor is configured to: detect when a right-side operation region provided on a right side of a steering wheel has been operated; detect when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.

There is provided a method of displaying an image on a display device, the method including moving an image displayed at an image display region of the display device, and reducing a first region and enlarging a second region, the first and second regions included in the image, wherein the image has a smaller size than the image display region.

Provided are a display control adjustment method, a terminal, and a computer-readable storage medium. The method includes: selecting a display control to be adjusted from a current display interface; generating a control instruction according to a position of the display control to be adjusted with respect to the non-display region; and adjusting, according to the control instruction, the control region of the display control to be adjusted and a content display mode of the display control to be adjusted, so that display content in the display control to be adjusted is displayed in a display region of a display.

A video display device comprising; a display; an exercise amount detection sensor configured to detect an exercise amount of a viewer while the viewer is viewing content displayed and output sensor information; a timer that measures a viewing time; and a processor. The processor: acquires the viewing time from the timer; calculates the exercise amount of the viewer based on the sensor information acquired within a predetermined period of viewing time; compares the exercise amount with an exercise facilitation threshold for determining whether to facilitate exercise for the viewer; displays a specific object within a display area of the display when the exercise amount falls below the exercise facilitation threshold; and moves the specific object from an inside of the display area to an outside thereof in accordance with an external coordinate system expressing a position in a real space associated with a two-dimensional coordinate system in the display area.

An image processing device is an image processing device configured to cause a display to display three-dimensional data as a three-dimensional image, the three-dimensional data representing a biological tissue. The image processing device includes: a control unit configured to detect a series of positions of a catheter inserted into the biological tissue from data obtained in time series by a sensor observing the surrounding of a lumen of the biological tissue while moving in the lumen, and to switch a display mode between a first mode for displaying a first figure representing the series of positions in the three-dimensional image, and a second mode for displaying a second figure representing one position among the series of positions in the three-dimensional image.
