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

Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may receive at least one input image for a scaling operation, the at least one input image being associated with one or more scanning windows, each of the scanning windows including a plurality of pixels. The apparatus may also detect one or more features in the plurality of pixels in each of the one or more scanning windows. Further, the apparatus may adjust an amount of the plurality of pixels in each of the scanning windows for each of the detected features. The apparatus may also combine the adjusted amount of the plurality of pixels for each of the detected one or more features into a plurality of output pixels. The apparatus may also process each of the plurality of output pixels into at least one output image.

Fuzzy logic-based pattern matching and corner filtering for display scaler

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

Described herein is a system and method that relates to mapping from one color space on a 3D cube to another, and an addressing method used to represent the data. The system organizes the data to reduce memory storage requirements, by re-using redundant information from different cube corners in a lattice structure without re-storing the same data. The lattice structure may repeat for every cube of interest.

Systems and methods for mapping color data

A system and method for generating an interpolated pixel at a vertical position in a field of a video frame. The method comprises the steps of receiving at least two pixels vertically adjacent the vertical position in the field and at least three pixels from at least one adjacent field, detecting a degree of motion in the vicinity of the interpolated pixel, providing weighting factors based on the degree of motion, and calculating the interpolated pixel based on a combination of weighted contributions from the at least two pixels and the at least three pixels. The weighted contributions are derived from a combination of the weighting factors and at least vertical-temporal and temporal interpolation. For at least one degree of said motion, the weighted contributions comprise at least (i) a first positive contribution derived from immediately adjacent ones of the at least two pixels, (ii) a second positive contribution derived from a central one of the at least three pixels located at the vertical position, and (iii) a negative contribution derived from the two of the at least three pixels that are immediately vertically adjacent the central pixel.
