A broadcast reception device receives a digital broadcast service capable of executing an application cooperating with a broadcast program, and is provided with: a broadcast reception unit which receives broadcast waves of the digital broadcast service; a separation unit which separates video information relating to the broadcast program and application-related information from the received broadcast waves; a broadcast video decoding unit which decodes the video information relating to the broadcast program; an application acquisition unit which acquires an application on the basis of location information included in the application-related information; an application execution unit which executes the acquired application and acquires additional data from a server device; a video conversion unit which converts broadcast program video decoded by the broadcast decoding unit into high-quality video having a higher quality than the video using the acquired additional data; and a display unit which is able to display the high-quality video.

Methods, apparatuses, and non-transitory machine-readable media for displaying information and/or images on a display of a computing device based on received data. Apparatuses can include a display screen, a memory resource, a recognition sensor, and a controller. An example controller can receive data and activate information and/or images on a display screen based in part on the received data. In another example, a method can include storing recognition data in a memory resource, receiving primary recognition data, comparing the primary recognition data to the stored recognition data, and activating the display screen for a viewing angle responsive to authentication of the primary recognition data through the comparison of the primary recognition data and the stored recognition data.

A display device includes a display panel including a first pixel having a first viewing angle and a second pixel having a second viewing angle different from the first viewing angle, and a display panel driver which applies data voltages to the first pixel and the second pixel and renders coordinate image data for one coordinate of input image data for one rendering unit, and the one rendering unit only includes one of a first sub-pixel included in the first pixel and a second sub-pixel included in the second pixel.

An electronic device is provided that includes a layered screen configured to present an image. The electronic device includes a memory to store executable instructions, and one or more processors. When implementing the executable instructions the one or more processors are configured to generate the image at a determined distance and location from the screen at a convergence focal location. The image is in focus at the convergence focal location and out of focus elsewhere.

The present application provides a screen projection method, a receiving end device, and a sending end device. The receiving end device performs active wireless scanning and searching on the sending end device, and when the sending end device is scanned, establishes a wireless connection with the sending end device; and once the wireless connection is established, the receiving end device automatically sends a screen projection code to the connected sending end device, and the sending end device may prompt a user to perform a screen projection operation by means of displaying the screen projection code. In this process, there is no need for the user to perform complicated manual operations, the sending end device can automatically acquire the screen projection code, and prompts the user to perform the screen projection operation in a timely manner, thereby improving the timeliness of the screen projection operation.

A personal computer includes an output interface configured to output an image signal to a projector, an image processing section configured to generate a second image obtained by reducing visibility of the first image, and a second control section configured to, when a first condition is satisfied, cause the output interface to output a second image signal based on the second image and, when a second condition is satisfied, cause the output interface to output a first image signal based on the first image.

A non-transitory computer-readable storage medium storing a computer program stored in a computer readable storage medium is provided. The computer program causing a computer to prevent an illegal leakage of an image displayed on a display device of the computer includes receiving operation mode information from a server after the computer is booted, determining whether an operation mode of the computer program is a photographing attempt prevention mode or a violation detection mode based on the operation mode information, determining whether communication between the server and the computer is possible, executing the photographing attempt prevention mode when the operation mode is the photographing attempt prevention mode and the communication is possible, and executing forcibly the photographing attempt prevention mode even if the operation mode is the violation detection mode when the operation mode is the violation detection mode and the communication is not possible.

In one example in accordance with the disclosure, a computing device is described. An example computing device includes a gaze tracking device. An example gaze tracking device identifies, from a captured image, a gaze region for a user viewing a display device coupled to the example computing device. The gaze region indicates a location on the display device where the user is looking. The example computing device includes a controller. An example controller determines a first window on the display device that is aligned with the gaze region and based on a determination that the first window is aligned with the gaze region, adjusts a video setting of a second window that is outside the gaze region.

A display apparatus capable of displaying previously-displayed presented data stored in association with meeting identification information identifying each meeting, includes circuitry configured to receive particular meeting identification information stored at an information processing apparatus from the information processing apparatus; and display at least a part of particular presented data associated with the received particular meeting identification information, on a display.

A method for displaying screen information includes obtaining visitor information of a visitor of a display device. Once a page to be visited by the visitor is determined, a current color scheme for at least one controllable element of the page to be visited is determined according to the visitor information and a page type of the page to be visited.
