This disclosure provides systems, methods, and devices for the prevention of color leakage in Field Sequential Display while maintaining display brightness. In a first aspect, a method of signal processing includes receiving a first frame of a first color of image data; selecting a modified first frame of the first color by applying a recursive filter to the first frame, wherein the recursive filter is associated with at least one previous frame of a second color different from the first color; and selecting first pixel drive values associated with the modified first frame. Other aspects and features are also claimed and described.

Overdrive technique for faster switching in field sequential display

The present disclosure relates to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may receive a plurality of panel measurements for a display panel, each of the plurality of panel measurements associated with a plurality of subpixels in the display panel. The apparatus may also determine, upon receiving the plurality of panel measurements, at least one offset for one or more subpixels of the plurality of subpixels associated with each of the plurality of panel measurements. The apparatus may also store, upon determining the at least one offset for the one or more subpixels, the at least one offset for the one or more subpixels associated with each of the plurality of panel measurements.

Adaptive subsampling for demura corrections

The present disclosure relates to methods and apparatus for display processing. In some aspects, the apparatus can measure at least one panel including one or more panel measurements. The apparatus can also determine at least one correction factor for each of the one or more panel measurements. Further, the apparatus can adjust the at least one correction factor based on each of the one or more panel measurements. In some aspects, the apparatus can compress the at least one correction factor based on each of the one or more panel measurements. Moreover, the apparatus can store the compressed at least one correction factor. In some aspects, the apparatus can decode correction data for at least one frame based on the adjusted at least one correction factor. The apparatus can also store or communicate the decoded correction data for the at least one frame.

Methods and apparatus for utilizing display correction factors

The present disclosure relates to methods and devices for display processing. The device can receive a first image including a plurality of first pixels. Each of the first pixels can include a first red, green, blue (RGB) color value. The device can also determine an RGB adjustment value based on a lens correction value. Additionally, the device can determine a second RGB color value for each first pixel based on the determined RGB adjustment value. The device can also generate a second image including a plurality of second pixels, where each of the second pixels includes a determined second RGB color value. Moreover, the device can separate at least one of a red color value, green color value, or blue color value of the RGB color value and adjust at least one of a red color value or a blue color value based on the lens correction value.

Methods and apparatus for inline chromatic aberration correction

Techniques are described in which a device is configured to retrieve a metadata buffer for rendering a sub-frame of a set of sub-frames for a frame. A data block of a data buffer is configured to store image data for rendering the sub-frame. In response to determining, based on the metadata buffer for rendering the sub-frame, that the sub-frame includes a color pattern, fixed color value, or combination thereof, the device refrains from retrieving the image data from the data block of the data buffer and determines the image data for rendering the sub-frame based on the metadata buffer.

Fetch reduction for fixed color and pattern sub-frames

An integrated circuit includes first and second voltage domains. The first voltage domain is associated with a positive voltage supply grid and the second voltage domain is associated with a selectably on voltage supply grid. A switch is used to selectably switch on and off the selectably on voltage supply grid to power the second voltage domain. A buffer cell cluster of at least on initial buffer cell and a pair of insulator cells is coupled to the positive voltage supply grid electrically independent of the nodes of a switch and is capable of buffering a feed-through signal having a logic one voltage level defined substantially at the voltage level of the positive voltage supply grid. The buffer cell cluster has two distal ends. buffer cell cluster, at one distal end, is coupled to a first insulator cell of the pair of cells while, at the other distal end, the buffer cell cluster is coupled to a second insulator cell of the pair of the cells.

Method and apparatus for buffering signals in voltage domains

A system and method are provided for reducing power consumption within a video processing portion of a system. Activity associated with an instruction buffer is monitored to determine whether power consumption modes can be initiated within a system. If a number of pending instructions within an instruction buffer is greater than a particular threshold value, a normal mode of operation is initiated. If the number of pending instructions is less than the threshold value, the system is put in a reduced mode of operation. In the reduced mode of operation, processing is reduced to lower power consumption within the system. Accordingly, power consumption is altered to match a level of activity within the instruction buffer.

System for reduced power consumption by monitoring instruction buffer and method thereof

The present invention includes a method and apparatus for graphics processing in a handheld device including a transform engine capable of receiving vertex information. The transform engine generates a plurality of vertices from the vertex information, wherein each of the vertices includes a corresponding bin identifier. The method and apparatus further includes view frame factors defining a clipping region such that when any of the plurality of vertices is within the clipping region, a clip identifier is generated for that vertex using the corresponding bin identifier. A vertex shader coupled to a clipping module, wherein the clipping module generates supplemental vertices and the vertex shader receives the supplemental vertices therefrom. The vertex shader combines the supplemental vertices with the bin identifiers and are provided to a vertex buffer.
