Video displayers are provided for detecting image freezing in a video displayer with a multi-layer panel including a front layer and a pixel layer emitting pixel light in emitting direction towards the front layer. Front layer and pixel layer are configured to let light through. Video displayers further include a light reflector arranged in the multi-layer panel between pixel layer and front layer to reflect the pixel light from pixel layer in reflection direction towards pixel layer; a light sensor arranged to receive the reflected pixel light at receiving location and sense light variations in received reflected pixel light; and a control unit to receive light variations sensed by light sensor and to detect image freezing depending on received sensed light variations. Methods and computer programs implementing such methods are also provided which are performable by proposed video displayers.

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.

There is provided an image processing device that processes a projection image presented to a plurality of persons at the same time. The image processing device specifies an overlapping area in which fields of view of two or more users overlap based on information on each user, classifies objects included in the overlapping area into a first object group and a second object group, generates a common image common to all users, made up of the first object group, generates individual images different for each user, made up of the second object group, and determines an output protocol for displaying the individual images.

A display control apparatus (2000) is configured to: acquire a target image (10) including a display apparatus (30) provided at an exhibition place (40) and a product (20) exhibited in the exhibition place (40); to recognize the product (20) included in the target image (10), and acquire relevant information (54) of the product (20); determine, based on a relative positional relationship within the target image (10) between the product (20) and the display apparatus (30), a display position at which a display (32) representing the relevant information (54) of the product (20) is displayed in the display apparatus (30); and display the display (32) of the product (20) at the determined display position on the display apparatus (30).

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.

Provided is a method of calibrating a stereoscopic display device. The device includes a motor and a display panel, and the display panel is driven by the motor to rotate to realize a stereoscopic display. The method includes acquiring a control strategy of the motor and display parameters of the display panel matching the control strategy, wherein the control strategy indicates that each time the motor runs for a preset period of time, the motor is restarted; controlling the motor to run according to the control strategy, to calibrate the motor by restarting; and driving the display panel to display according to the display parameters in the rotation process of the motor.

A streaming media device includes a printed circuit board hosting components configured to access internet data. An audio/visual connector is linked to the printed circuit board, wherein the audio/visual connector is adapted for connection to an audio/visual device, wherein the audio/visual connector is adapted to operate with a first audio/visual interface having sufficient power to fully operate the printed circuit board and a second audio/visual interface having insufficient power to fully operate the printed circuit board. A power connector is linked to the printed circuit board, wherein the power connector selectively receives power based on the audio/visual connector utilizing one of the first audio/visual interface and the second audio/visual interface.

A convertible panel includes a number of sub-panels which are movable between a first position in which the panels extend in the same plane to define a unified panel and a configuration in which one or more of the panels are moved into other planes which allow them to form steps. Multiple of the rotated panels may form a sequence of steps, e.g. a staircase. The convertible panel may be moved via a robotic mount, whereby the position or orientation of the convertible panel may be changed.
