Claim 0:
1. A method comprising:
receiving an image frame comprising a plurality of pixels arranged in a plurality of rows and columns, wherein the pixels comprise image data associated with a scene and fixed pattern noise introduced by an imaging system;
detecting whether motion is present at the imaging system;
if motion is detected, performing a first process to determine a correction term configured to reduce the fixed pattern noise for a selected one of the pixels, wherein the first process comprises comparing the selected pixel to a plurality of neighbor pixels of a first kernel;
if motion is not detected, performing a second process to determine whether to replace the selected pixel to reduce the fixed pattern noise, wherein the second process comprises determining a plurality of linearity measurements based on the selected pixel and a plurality of neighbor pixels of a second kernel; and
applying the correction term to the selected pixel in response to the first process or replacing the selected pixel in response to the second process.
