1. A method comprising:
receiving an input image from an image sensor;
determining localized color correction parameters for a selected color and a selected dimension in a color space where dimensions defining the color space are independently adjustable, wherein the determining further comprises:
selecting an angle on a color plan;
selecting a target angle on the color plan; and
applying a function between the angle and the target angle to determine the localized color correction parameters;
applying the localized color correction parameters to the input image to generate an output image, wherein the applying further comprises:
rotating the target angle towards the angle to generate a rotated color plan; and
blending the color plan and the rotated color plan to generate the localized correction parameters, the angle and the target angle representing the selected dimension on the color plan and the rotated color plan; and
storing, displaying, or transmitting the output image based on at least the localized color correction parameters.
