TEMPORAL DENOISER QUALITY IN DYNAMIC SCENES
Apparatuses, systems, and techniques are presented to reduce temporal lag when a dynamic event is occurring in computer generated video. In one embodiment, a first averaging algorithm is utilized to determine a display value for a pixel based at least in part on previous pixel values. Once a dynamic event is detected, a set of the previous pixel values is averaged using a second averaging algorithm. The pixel value is updated based on the first averaging of the pixel values and the second averaging of the pixel values to determine a current pixel value.
Device and method for processing frames
Embodiments disclosed herein relate to device and method for processing frames. For example, a buffer of a device is arranged to store a plurality of rendered frames rendered at a frame rendering rate and a time stamp for each of rendered frames. A compositor of a device is arranged to obtain a timestamp of a synchronisation signal for synchronising the display of frames with a display refresh rate. In response to obtaining a timestamp of a synchronisation signal, a compositor is arranged to trigger access to a buffer to obtain two rendered frames having timestamps closest to a timestamp of a synchronisation signal. An interpolator of a device is arranged to generate an interpolated rendered frame for display by performing an interpolation operation using two rendered frames. An interpolation operation takes into account the difference between timestamps of each of two rendered frames and a timestamp of a synchronisation signal.

A display device and an afterimage compensation method thereof are proposed. The display device and the afterimage compensation method thereof capture an input image frame at a predetermined period, detect an edge area in the captured image frame, detect an afterimage compensation area on the basis of the cumulative count detected as the edge area for each pixel, and perform individual afterimage compensation only on a pixel whose cumulative count detected as the afterimage compensation area is greater than or equal to a predetermined threshold value. Accordingly, the afterimage compensation time may be shortened by individually performing the afterimage compensation according to a condition of each pixel.
Graphics processing systems
When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, wherein the first version of the frame is rendered in its entirety but only a portion of the second version of the frame is rendered. The rendered portion of the second version of the frame is compared to a corresponding rendered portion of the first version of the frame. When the comparison determines that the two portions of the two versions match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines the two portions of the two versions do not match, an error operation is performed.
