Embodiments of the present disclosure describe an electronic device for providing a visual effect corresponding to a gesture input. The electronic device includes a sensor, a wireless communication circuit, a display device, and at least one processor. The at least one processor is configured to sense a gesture input through the sensor. The at least one processor is also configured to control the display device to display a first visual effect corresponding to the gesture input.

Disclosed are systems and methods for superimposing a virtual image on a real-time image. A system for superimposing a virtual image on a real-time image comprises a real-time image module and a virtual image module. The real-time image module comprises a magnification assembly to generate a real-time image of an object at a first location and a first depth, with a predetermined magnification. The virtual image module generates a virtual image by respectively projecting a right light signal to a viewer's right eye and a corresponding left light signal to a viewer's left eye. The right light signal and the corresponding left light signal are perceived by the viewer to display the virtual image at a second location and a second depth. The second depth is related to an angle between the right light signal and the corresponding left light signal projected to the viewer's eyes. The second depth may be approximately the same as the first depth.

Example video ingestion cables, display systems, and methods for harmonizing video formats for video ingestion are provided. An example video ingestion cable includes a first video interface connector cable to receive a first video feed formatted according to a first video format, a second video interface connector cable to receive a second video feed formatted according to a second video format, a format conversion circuit to convert the first video feed or the second video feed to a harmonized video format, and an output interface connector to transmit one of the first video feed and the second video feed as an output video feed formatted according to the harmonized video format to a display device. An example display system includes first and second video ingestion cables and a video ingestion circuit to select an input video feed for display.

Embodiments of this application provide a multi-window display method, a first electronic device, and a second electronic device. The method is applied to the first electronic device and the second electronic device that communicate with each other. When a plurality of applications run on a mobile phone, a plurality of windows of the mobile phone can be displayed on a PC, and each window is correspondingly used to display a different application. A user can perform an operation on each mobile phone application by using a window that corresponds to the mobile phone application and that is displayed on the PC. In addition, the operation performed by the user on the mobile phone application on the PC does not affect use of another function of the user on the mobile phone. This improves office efficiency such as file sharing, and improves user experience.

A display control method includes outputting, by at least one video output device, M videos, M being an integer larger than or equal to 1, if M<N, displaying the M videos in each of M sub-areas by respectively assigning each of the M videos to each of the M sub-areas obtained by dividing a single large area in which an image is displayed by N display devices, N being an integer larger than or equal to 2, and if M=N, displaying each of the M videos by assigning each of the M videos to each of N display areas corresponding to the N display devices respectively.

A circuit device includes a storing section configured to store a rendering image and a warp processing section. The warp processing section includes a coordinate converting section, a coordinate-address converting section, and an output section. The coordinate converting section converts, with coordinate conversion based on warp parameters and rotation correction parameters, an output coordinate, which is a coordinate on a display image, into an input coordinate, which is a coordinate on the rendering image. The coordinate-address converting section converts the input coordinate into a read address of the storing section. The output section reads out pixel data of the rendering image from the read address of the storing section and outputs, based on the read-out pixel data, pixel data in the output coordinate of the display image.

A display panel control chip including a processor and a signal processing circuit is provided. The processor controls a display panel to display first and second images corresponding to first and second video signals. The first image is adjacent to the second image by a border extending in perpendicular to a first direction at a first coordinate. The signal processing circuit stores the first coordinate, determines whether a first cursor is in the first image or the second image according to a cursor control signal and the first coordinate, and transmits, according to the determination, the cursor control signal to either a signal source of the first video signal or a signal source of the second video signal. When an area ratio of the first image to the second image is changed, the processor controls the signal processing circuit to update the first coordinate.

A flexible display device is provided. The flexible display device includes: a display; a sensor configured to detect at least one rolling characteristic in response to the display being rolled; and a controller configured to perform a first function of the flexible display device based on the detected at least one rolling characteristic.

An information processing apparatus is used in contact with a user and includes a processor. In a case where multiple objects as candidates for operation are present in an object image taken by a camera or an object image acquired externally, the processor is configured to detect one or more of the objects present at a center position of the object image as the candidates for operation or detect one or more of the objects superposed on a user image of a part of a body of the user operating the information processing apparatus as the candidates for operation.

The signal processing device according to an embodiment of the present disclosure includes: a frame buffer to store an input image and output an output image, an output synchronization signal calculator to calculate an output synchronization signal based on an input synchronization signal and a size or a position of the output image in comparison with the input image, and an output synchronization signal output interface to output a variable output synchronization signal of which a start timing changes based on a signal from the output synchronization signal calculator, wherein a difference between a start timing of the input synchronization signal and a start timing of the output synchronization signal changes based on the size of the output image. Accordingly, a delay time may be reduced in response to the output image having a size different from a size of the input image being output.
