Abstract
An electronic device includes an electronic display configured to present an image based on image data and a display pipeline having image processing circuitry to process the image data for display on the electronic display by receiving the image data, referencing a lookup table (LUT) to determine output values based on a plurality of input value sets associated with the image data, the LUT including entries respectively mapping an output value to a defined input value set, determining whether an input value set of the plurality of input value sets is represented by the entries of the LUT, performing curvature interpolation to determine an interpolated output value associated with the input value set in response to determining the input value set of the image data is not represented by the entries of the LUT, and applying the interpolated output value to the input value set to generate updated image data.
