1. A method of reducing false color artifacts in an image, the method comprising: determining an aperture value based at least in part on brightness values of pixels in a window surrounding a subject pixel; determining a color saturation value based at least in part on color values of pixels in the window; determining an attenuation value based at least in part on the aperture value and the color saturation value; and adjusting a color value of the subject pixel based at least in part on the attenuation value, wherein the color saturation value is proportional to color saturation within the window, wherein the window is a 3×3 pixel window and the subject pixel is located at the center of the window, and wherein the color saturation value is determined by: averaging an absolute value of color value of each corner pixel in the window with absolute values of color values of respective neighboring pixels within the window to obtain a respective average color value for each corner pixel in the window; comparing each average color value with the absolute value of the color value of the subject pixel; and selecting the average color value closest to the color value of the subject pixel.
