A method for extracting display data from a computing resource of a computer system comprises the dynamic selection of a display capturing mode among a plurality of display capturing modes.

There is provided an information processing device including: a user information management unit configured to set a user in a window in which an operation screen of an application is displayed and grant at least one of execution authority of the application set in the window according to the user and browsing authority of content in the window to the window.

A relay device includes: a case which holds a mobile terminal, the mobile terminal being attachable to and detachable from the case; a first interface to which the mobile terminal held in the case is connected; a second interface with which the external display device is connected; and a controller housed in the case. The controller includes: an obtainer which obtains a video signal and first notification information from the mobile terminal via the first interface; and a superimposer which superimposes second notification information on the video signal based on the first notification information, and outputs the video signal on which the second notification information is superimposed to the external display device via the second interface. The second notification information is obtained by at least one of deletion or replacement of at least a portion of the first notification information.

There is provided a method of controlling the operation of a first electronic device having a first display screen, the method comprising obtaining (101; 111) measurements of a position of the first electronic device relative to a second electronic device, an orientation of the first display screen, and/or an orientation of a second display screen of a second electronic device; determining (103; 113), using the obtained measurements, one or both of (i) whether a first user using the first electronic device can view the second display screen, and (ii) whether a second user using the second electronic device can view the first display screen; and controlling (105; 115) the display of information on the first display screen based on the result of the step of determining.

The present invention provides a viewing angle mode switching method of a liquid crystal display device and the liquid crystal display device. A viewing angle mode switching request is received. The target view mode is a first viewing angle mode or a second viewing angle mode. A timing relationship between the second scanning signal and the first scanning signal is adjusted, according to the viewing angle mode switching request. The liquid crystal display device is instructed to switch between the first viewing angle mode and the second viewing angle mode, according to a change of the timing relationship between the second scanning signal and the first scanning signal. With implementing the embodiments of the present invention, switch between different viewing modes can be achieved, and the display convenience of the liquid crystal display device can be improved.

An electronic apparatus includes: a primary display screen and a secondary display screen located in different areas of the electronic apparatus respectively; the primary display screen is configured to display in a first display mode; the secondary display screen is configured to display in a second display mode; the first display mode is that after the electronic apparatus is turned on, in a non-standby state, the display screen is in the display enabled state, and in a standby state, or after the electronic apparatus is turned off, the display screen is in a display disabled state; and the second display mode is that after the electronic apparatus is turned on, the display screen is always in a display state. The apparatus may save electric energy of the electronic apparatus. A controlling method for the electronic apparatus is further provided.

A server includes a virtual machine to execute a remote graphics generation protocol. Execution of the remote graphics generation protocol determines a protection label to be inserted within a bitmap that is to be transmitted for display on a client machine associated with the virtual machine, and determines at least one optimization technique to be performed on the bitmap. A determination is made on if the at least one optimization technique, if performed, alters the at least one protection label when inserted within the bitmap. The protection label is inserted within the bitmap.

According to an example, at least one user in proximity to a display is detected with a camera. A primary user and eye gaze are determined. The location of a secondary user relative to the display is calculated, and an active screen area and an inactive screen area based on the eye gaze are determined. A first angle and a first brightness for the active screen area and a second angle and a second brightness for the inactive screen area based on the location of the secondary user are calculated, and focus area boundaries for the active screen area based on the location of the secondary user are calculated. The first angle, the first brightness, and the focus area boundaries are applied to the active screen area, and the second angle and the second brightness are applied to the inactive screen area.

Embodiments of the present invention provide for hiding information in an image. A first pixel point and a second pixel point that are adjacent in an image are extracted. A first sub-pixel of the first pixel point and a second sub-pixel of the second pixel point that are to be combined during display on a display device are determined, wherein the display device determines a combined pixel value according to pixel values of the first sub-pixel and the second sub-pixel in a predefined manner. Information is hidden using parity properties of a sum of pixel values of the first sub-pixel and the second sub-pixel while the combined pixel value determined according to pixel values of the first sub-pixel and the second sub-pixel in the predefined manner is kept unchanged. By using unique display characteristics of a display device, information is hidden in an image without changing display effect of the image on the display device.

An information processing method includes sending, by a first electronic device, content displayed on the first electronic device to a second electronic device through a communication connection between the first electronic device and the second electronic device; detecting operation instruction information; and determining a display state of the first electronic device based at least on the operation instruction information.
