Abstract:
1. A method for minimizing interframe noise in an image processing system, the method comprising: providing a target setting for an image control feature in the image processing system; providing a storage unit configured to store a state information associated with the image control feature, the state information being either a first state or a second state; providing a tolerance for the image control feature, the tolerance being a first value in the first state, the tolerance being a second value in the second state, the first value being a narrow tolerance and the second value being a wide tolerance; receiving a frame of data corresponding to a video frame; determining an image control feature measurement from the frame of data, the image control measurement being associated with the image control feature; calculating an error value using the image control feature measurement and the target setting; determining if the error value exceeds the tolerance; in response to determining that the error value exceeds the tolerance, setting the state information to the first state and converging the image control feature measurement toward the target setting; and in response to determining that the error value does not exceed the tolerance, setting the state information to the second state and maintaining the image control feature.
