A method and an imaging system for adaptive shutter control wherein an imaging system can be configured to actuate a calibration element at various times and develop an offset correction or Non-Uniformity Correction (NUC). The system control processing units may acquire information derived from calibration data, regular imaging data or external data, which may be correlated with how fast the NUC is changing over time. How often calibration element is actuated may be adaptively determined from the correlating information and the actuation times may be adaptively controlled to optimally actuate as needed. In some embodiments the calibration element may be a shutter and calibration activation may include closing the shutter and providing a flat field image for calibration purposes.

Time based offset correction for imaging systems and adaptive calibration control

In some embodiments, methods or systems may be provided for an imaging system including an imaging sensor, wherein frames or sub-frames of intensity data may be acquired from some or all pixels of the frame, and a moving kernel, smaller than the frame or sub-frame, is moved over the frame for analysis. The values of the center column of the kernel may be compared to the outer column values of the kernel and a column offset for the center column may be determined. Only one offset value may be stored at any one time for each pixel in the frame or sub-frame.
