Minimization of fixed pattern noise in images of moving scenes
An exemplary method implements fixed pattern noise compensation for captured visual images of a moving scene. A current X-by-Y frame of image values captured by a camera is stored in memory where the magnitude of each image value represents a light level associated with a respective X-by-Y position...

| description | An exemplary method implements fixed pattern noise compensation for captured visual images of a moving scene. A current X-by-Y frame of image values captured by a camera is stored in memory where the magnitude of each image value represents a light level associated with a respective X-by-Y position in the frame. A moving average value for each image value over a number of X-by-Y frames is determined where the moving average value for each X-by-Y image value represents a level of fixed pattern noise for the moving scene. X-by-Y frames with fixed pattern noise compensated image values are generated based on subtracting from each image value of the current X-by-Y frame the corresponding moving average value. |
