An application engine renders an image based on image data from a content source. A display engine displays the image to a user. The image is adjustable from a first size to a second size. A detection system detects the size adjustment. An application executes a clarification routine to maintain sharpness of the image.

Disclosed herein are techniques to provide notification of the type and/or attributes of frame updates. A platform can notify a panel of further frame updates, whether the frame update is a full frame update or a partial frame update and attributes of the frame update. The platform can notify the panel of information about the frame update during a vertical blanking interval by asserting a command or signaling the panel using selected symbols during the vertical blanking interval.

The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor including a scaler to generate second image frame data scaled down in comparison with the first image frame data; and an output interface to output the first image frame data and the second image frame data, wherein the scaler generates at least one super pixel or super block and outputs the scaled down second image frame data including the super pixel or the super block. Accordingly, it is possible to generate the scaled down second image frame data with reduced error as compared to the first image frame data.

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.

A temperature control method is provided. In the method, a terminal determines a current temperature of the terminal and determines, based on a preset corresponding relationship between a screen display frame rate and a temperature interval, a target temperature interval of the current temperature of the terminal in the preset corresponding relationship. The terminal may determine a target screen display frame rate corresponding to the target temperature interval. And the terminal may adjust a current screen display frame rate of the terminal to the target screen display frame rate, to control the temperature of the terminal to be within a preset temperature range.

Aspects of the present disclosure can receive a hardware Vsync signal from a display, generate a hardware timestamp signal based on the hardware Vsync signal, determine an error for a pulse in the hardware timestamp signal, determine whether the error for the pulse is over a threshold, synchronize a software Vsync signal based on the hardware timestamp signal, wherein the pulse of the hardware timestamp signal is ignored in synchronization based on whether the error is above the threshold, and control rendering and transmission of a frame to the display based on the synchronized software Vsync signal.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A time code display system comprising: a video receiver configured for receiving a plurality of non-homologous video signals; a time code parser connected with the video receiver and configured for extracting time code data of each video frame from each video signal; a write controller and a buffer, the write controller being connected with the video receiver and the time code parser; a synchronous clock component configured for generating a local clock signal according to a channel associated clock signal of any video signal; and a read controller and a display, the read controller being connected with the synchronous clock component and the buffer and configured for reading out the video frame of each video signal and the time code data corresponding to the video frame from the buffer at the same time, according to the local clock signal.

Content presented on a display screen is updated responsive to a user input. Content is retrieved and segmented into bands that are rendered onto the display screen incrementally to provide a visual effect similar to an animation. A band is rendered at a starting location and after a refresh interval passes a subsequent band is rendered at a second starting location. The bands may be rendered until the content is shown on the display screen.

An electronic device includes: a host configured to output image data and a timing control signal in response to an image intended to be displayed; a display driver IC coupled to the host through a first interface and a second interface and configured to output a data signal based on the image data; and a display configured to display an image based on the data signal, wherein the host is configured to output the image data and the timing control signal through any one of the first interface and the second interface depending on a display mode.
