An electronic device includes a transparent first display panel, a second display panel and a processor electrically connected to the two panels. The first display panel is movable with respect to the second display panel. The processor is configured to switch between a plurality of display modes based on relative positioning of the two panels and to provide video signals to the two panels based on a current display mode. When the first display panel is parallel to the second display panel and faces a display area of the second display panel, the processor executes a stereoscopic display mode. When an angle between the two panels is between 0 and 180 degrees, exclusive, the processor executes an augmented reality display mode. When the display areas of the two panels are oriented away from each other, the processor executes a dual display mode.

A method for of encoding an application screen comprises partitioning graphic data into a plurality of graphic layers and classifying each of the plurality of graphic layers as either a screen content (SC) or a non-screen content (non-SC) layer. The method further comprises classifying each of the plurality of graphic layers as either a screen content (SC) or a non-screen content (non-SC) layer. Further, the method comprises rendering and encoding the one or more SC layers using a first codec and the one or more non-SC layers using a second codec.

A system and method is disclosed that allows multiple casting devices to work together to populate a large display screen according to the subject matter disclosed herein. The system includes a receiving device that includes two or more screen-cast receivers and a controller. Each screen-cast receiver receives from a corresponding casting device at least a portion of a frame of original content of the corresponding casting device generated in a native resolution of the corresponding casting device. The controller synchronizes each received portion of the frame of the original content of the corresponding casting device to form a video output signal that comprises a combination of each received portion, in addition to any internally generated content derived by the receiving display. A casting device may be a smartphone, a tablet, or a computing device, such as a laptop computer.

Provided is a display device. The display device includes a first processor, a second processor, and a display screen. The first processor is configured to acquire at least two OSD images, and to form a combined image with at least two OSD images and send the combined image to the second processor. The second processor is electrically coupled to the first processor and is configured to receive the combined image, identify at least two OSD images from the combined image, acquire a first screen and acquire a second screen by superimposing at least two OSD images onto the first screen, and output the second screen to the display screen. The display screen is electrically coupled to the second processor and is configured to display the second screen.

Systems, devices, and methods for generating, processing, assembling, and/or formatting data for display are described. Example display controllers are described in which image data is stored in a framebuffer, and a compositor selectively retrieves portions of the image data. At least one P-operator produces lines of intermediate P-operated data by performing at least one intra-line operation on the image data retrieved by the compositor, such as repeating or reordering pixels of the image data. A Q-operator produces a stream of pixel data by performing inter-line operations on the intermediate P-operated data, such as interpolating between lines of the P-operated data. A display is driven according to the stream of pixel data.

In one embodiment, an electronic device includes a video-in interface, a video-out interface, memory circuitry, and processing circuitry. A first video stream with uncompressed frames is received via the video-in interface. The first video stream is compressed and then stored in a video buffer on the memory circuitry. For example, the uncompressed frames are individually compressed and stored in the video buffer. A second video stream with encoded frames is decoded and then played on a display device. For example, the encoded frames are decoded and then displayed on the display device via the video-out interface. The first video stream is then decompressed and played on the display device. For example, the compressed frames in the video buffer are individually decompressed and then displayed on the display device via the video-out interface.

A method for of encoding an application screen comprises partitioning graphic data into a plurality of graphic layers and classifying each of the plurality of graphic layers as either a screen content (SC) or a non-screen content (non-SC) layer. The method further comprises classifying each of the plurality of graphic layers as either a screen content (SC) or a non-screen content (non-SC) layer. Further, the method comprises rendering and encoding the one or more SC layers using a first codec and the one or more non-SC layers using a second codec.

An image processing apparatus includes an obtainment unit configured to obtain first image data obtained by capturing an image of an object, a generation unit configured to generate second image data representing a second image by performing conversion to maintain a specific gradation in a color saturation range in a case where a hue or color saturation of a region of interest in a first image represented by the first image data is converted according to a characteristic of a display unit, a conversion unit configured to perform conversion on the first image and the second image according to the characteristic of the display unit, and a display control unit configured to display the converted first image and the converted second image together on the display unit.

This disclosure describes a digital-content-transition system that dynamically determines a content-transition type for a visual media transition and converts a display of a digital-content-display device from one visual media item to another visual media item according to the content-transition type. For example, the digital-content-transition system can intelligently determine a type and time of transition from multiple content-transition types and content-transition times for transitioning between visual media items or visual media collections displayed at a digital-content-display device. By intelligently determining a content-transition type and a corresponding content-transition time based on metadata of the visual media items, the digital-content-transition system can transition a display of the digital-content-display device between visual media items or visual media collections according to the content-transition type and content-transition time.

Methods and apparatuses are disclosed herein for performing tone mapping and/or contrast enhancement. In some examples, a block mapping curve is low-pass filtered with block mapping curves of surrounding blocks to form a smoothed block mapping curve. In some examples, overlapped curve mapping of block mapping curves, including smoothed block mapping curves, is performed, including weighting, based on a pixel location, block mapping curves of a group of blocks to generate an interpolated block mapping curve and applying the interpolated block mapping curve to a pixel to perform ton mapping and/or contrast enhancement.
