Abstract
An image signal processing system may include processing circuitry that may reduce banding artifacts in image data to be depicted on a display. The processing circuitry may receive a first pixel value associated with a first pixel of the image data and detect a first set of pixels located in a first direction along a same row of pixels or a same column of pixels with respect to the first pixel. The first set of pixels is associated with a first band. The processing circuitry may then interpolate a second pixel value based on an average of a first set of pixel values that correspond to the first set of pixels and a distance between the first pixel and a closest pixel in the first band. The processing circuitry may then output the second pixel value for the first pixel.
