Video pipeline system and method for improved color perception
A system is provided for facilitating an enhanced video pipeline in order to improve color perception. The system comprises a first source configured to generate a first video stream, a second source configured to generate a second video stream, and a computing device. In this context, the computing device is configured to superpose the first video stream onto the second video stream, thereby generating an output video stream. The computing device is further configured to calculate weighting factors for individual pixels or discrete pixel sets of adjacent individual pixels of the output video stream by analyzing the first video stream and/or the second video stream.
Low latency variable backlight liquid crystal display system
In various examples, a low-latency variable backlight liquid crystal display (LCD) system is disclosed. The LCD system may reduce latency and video lag by performing an analysis of peak pixel values within subsets of pixels using a rendering device, prior to transmitting the frame to a display device for display. As a result, the display device may receive the peak pixel value data prior to or concurrently with the frame data, and may begin updating the backlight settings of the display without having to wait for a substantial portion of the frame to be received. In this way, the LCD system may avoid the full frame delay of conventional systems, allowing the LCD system to more reliably support high-performance applications such as gaming.
Dynamic frame rate conversion in active matrix display
The present invention provides a motion content based dynamic frame rate conversion method for displaying a video by a display device, comprising: detecting motion content of the video and generating a control signal for controlling a display color depth based on the motion detection result. The video is displayed with a lower color depth at a higher frame rate than a standard configuration of the display device if the motion detection result indicates that the video contains appreciable amount of motion content; and the video is displayed with a higher color depth at a lower frame rate than the standard configuration of the display device if the motion detection result indicates that the video is relatively static. The present invention can facilitate the display device to dynamically convert its display output formats according to motion content of the video to further optimize the display quality.
