The present disclosure relates to methods and devices for video or frame processing including an apparatus, e.g., a video or frame processor. In some aspects, the apparatus may receive a video stream including a plurality of frames, each of the plurality of frames including luminance information. The apparatus may also perform a histogram analysis on the luminance information for each of the plurality of frames. Additionally, the apparatus may determine whether a difference between the luminance information for each of the plurality of frames and a current luminance distribution is greater than a perceptual threshold. The apparatus may also calculate an updated tone mapping configuration based on the luminance information for a frame when the difference between the luminance information for the frame and the current luminance distribution is greater than the perceptual threshold.

Methods and apparatus for histogram based tone mapping

In some aspects, the present disclosure provides a method for bandgap voting. In some configurations, the method includes receiving, at a hardware voting component associated with a destination subsystem, metadata for each of a plurality of compressed display tiles, wherein for each of the plurality of compressed display tiles the metadata indicates an amount of compression of the compressed display tile. In some configurations, the method includes dividing the plurality of compressed display tiles into a plurality of sets of compressed display tiles. In some configurations, for each of the plurality of sets of compressed display tiles, the method includes determining a desired bandwidth for communicating the set of compressed display tiles over a bus, and receiving the set of compressed display tiles at the destination subsystem over the bus at an actual bandwidth that is based on the desired bandwidth.

Dynamic bandwidth voting

Methods, systems, and devices for processing display data are described. A device may receive a bitstream sequence including a quantity of intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. In some examples, the device may be a decoding device or an encoding device. Upon receiving the bitstream sequence, the device may determine a refresh pixel region for a frame based on an order of the quantity of intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. In some examples, the order may be an encoding order of the intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. The device may then send the refresh pixel region for the frame to a display device based on determining the refresh pixel region for the frame.

Display refresh blocks determination for video coding

A method for refreshing a display panel is described. The method includes receiving, at the display panel from post-processing hardware, a look-up table (LUT) based on a histogram of image data and a region of interest (ROI) of the image data. The method also includes applying, at the display panel, the LUT to at least a portion of cached data in panel memory to produce modified data. The method further includes refreshing the display panel based on the modified data.
