Claim One:
1. A method for implementing fixed pattern noise compensation for captured visual images by a camera of a moving scene comprising the steps of: storing a current X-by-Y frame of image values captured by the camera in memory where the magnitude of each image value represents a light level associated with a respective X-by-Y position in the frame; determining a moving average value for each image value over a number of X-by-Y frames where the moving average value for each X-by-Y image value represents a level of fixed pattern noise for the moving scene, where the number of X-by-Y frames used to determine the moving average values is inversely proportional to the speed at which the camera is moving; generating X-by-Y frames with fixed pattern noise compensation based on subtracting from each image value of the current X-by-Y frame the corresponding moving average value.
