Abstract
Embodiments relate to processing of pixels captured by a quadra image sensor. A quadra image sensor includes a plurality of pixel tiles, each having a plurality of pixels corresponding to the same color. A lens shading correction (LSC) circuit receives, for each of a plurality of colors, a set of gain tables. Each gain table corresponds to a different channel associated with the color. Each gain table includes a set of gain values, each associated with a location. The LSC circuit determines a pixel gain value for each pixel in a pixel tile and scales the pixels in the pixel tile based on the determined pixel gain values.
