Disclosed is a method for controlling screen backlight, the method includes: determining a basic setting value V0, where the basic setting value V0 is a value set for backlight brightness of a first screen and backlight brightness of a second screen; calculating a setting value V1 of the backlight brightness of the first screen and a setting value V2 of the backlight brightness of the second screen respectively based on V0; and adjusting the backlight brightness of the first screen and the backlight brightness of the second screen according to V1 and V2 respectively. Further disclosed are a device for controlling screen backlight, a multi-screen terminal, a storage medium, a method and device for setting screen backlight, and a multi-screen terminal.

An electronic device comprises a communication module, a display, a processor, and a memory, wherein the memory can control the communication module such that the processor performs a communication connection for screen sharing with an external electronic device, can acquire display information of the external electronic device from the external electronic device, can generate one or more pieces of transmission screen information on the basis of at least the display information of the electronic device or the display information of the external electronic device, and can determine the resolution or the screen ratio of the transmission screen information on the basis of at least the screen ratio of the external electronic device.

In one embodiment, a computing device receives a request from a mobile device of a user for an image. The computing device determines whether the user is associated with a preferred orientation for viewing an image. The preferred orientation is determined based on the user's usage patterns with respect to a particular application of the mobile device, or to the user's interactions with a social-networking system. If the user is associated with a preferred orientation, the image is adjusted to have the preferred orientation and to match display capabilities of the mobile device sending the request. The adjusted image is sent to the mobile device for display.

Disclosed is an electronic apparatus including a flexible display of which at least a portion is located at a first surface of the electronic apparatus and a first-surface exposed display size is changed, and a controller configured to display, when a first input corresponding to a first icon is received, content corresponding to at least one application of an application set corresponding to the first icon on the display based on layout information and application set information of the application set in response to the first input.

An image display device and image display method. The image display device includes: a plurality of display screens spliced together, a corresponding gravity sensor integrated in each display screen, a logic circuit electrically connected with each display screen and each gravity sensor respectively, and a memory electrically connected with the logic circuit. The gravity sensor determines a placing direction of a corresponding display screen. The logic circuit automatically adjusts an access sequence of the image information in the memory according to the placing directions of the display screens determined by the gravity sensors, and outputs the accessed image information to the corresponding display screens, so that the image display device can normally display images when the display screens are placed right way up and/or placed up side down.

A display control device includes: a receiver configured to receive an image signal; a measurer configured to measure the number of vertical scanning lines and horizontal scanning time of the image signal; a table generator configured to generate a provisional signal table when data measured by the measurer has not been retained in a previously prepared signal table; a detector configured to detect data for regulating an active display region of an image, from the image signal; and an updater configured to update the provisional signal table, based on a detection result by the detector.

An object of the present invention to provide a remote operating system and an information processing method which reduce a burden on a user's operation and suppress a user's erroneous operation. A remote operating system according to the present invention is a remote operating system which includes an operation target device and a remote operating device connected via a network, and in which a first controller causes a display signal interface to output a display signal for displaying a remote operating window corresponding to a selected window, and, when a cursor position is out of a movable area of a cursor, the second controller changes a position of the selected window and the cursor position such that the cursor position comes in the movable area of the cursor while maintaining a relative positional relationship between the position of the selected window and the cursor position.

A method of establishing a paid connection using a screen mirroring application between multi-platforms, where a transmitting end application is installed in a transmitting end apparatus of a sharing source and a receiving end application is installed in a receiving end apparatus of a sharing target. When establishing a connection, the transmitting end application confirms if an unique ID of the receiving end apparatus exists in an exception list, and if the receiving end application makes payment based on an operating system used by the transmitting end apparatus in order to determine establishing a limited or an unlimited connection between the transmitting end apparatus and the receiving end apparatus. Thus, the method assures that either the transmitting end application or the receiving end application is a paid version, a user complies with an application license agreement by using the exception list and the right of application developers is protected.

A source image is transformed into a destination image having a target aspect ratio. A reference region in the source image is defined. An extended region of interest of the source image having the target aspect ratio and containing the reference region is defined. A set of candidate image regions of increasing resolutions from the extended region of interest is determined, each having the target aspect ratio and containing the reference region. Candidate image regions are scaled to form a candidate target images. A quality metric is used to select a target image providing the best quality metric value.

The method of a portable device may includes the steps of setting a first mode based on a first folding angle between the first body and the second body and a second folding angle between the first body and the third body, displaying a first application in the first mode, detecting change of the first folding angle and change of the second folding angle in the first mode, detecting the changed first folding angle being equal to or greater than a first threshold angle and the changed second folding angle less than a second threshold angle and if it is detected that a rear side of the second body is in a state of being contacted with a different real object, switching the first mode to a second mode.
