Abstract:
1. A method of adjusting image data, comprising: receiving the image data corresponding to one or more pixels of an image; identifying a first color component value and a second color component value for a pixel in the image data within a two-color component color space; inputting the first color component value and the second color component value into a two-dimensional lookup table (2-D LUT); responsive to inputting the first color component value and the second color component value into the 2-D LUT, outputting a first color component adjustment value and a second color component adjustment value from the 2-D LUT; generating an adjusted first color component value by applying the first color component adjustment value to the first color component value; generating an adjusted second color component value by applying the second color component adjustment value to the second color component value; wherein the 2-D LUT is configured to be populated with color component adjustment values to correct for a known imperfection in an image capturing device having captured the image wherein the known imperfection is associated with the image capturing device, the known imperfection being a measure of a difference between colors captured by the image capturing device and known colors.
