Various embodiments of the present disclosure may include an imaging device configured to determine appropriate conditions for updating non-uniformity correction (NUC) terms. In certain embodiments, the imaging device may determine when the imaging device is likely not in use and update NUC terms during the times when the imaging device is likely not in use. Data from various position sensors such as gyroscopes, accelerometers, global positioning system receivers, and/or other data may be used to determine when the imaging device is likely not in use. Such position sensors may be coupled to the imaging device and/or may be remote from the imaging device. In certain embodiments, while NUC terms are updated, imaging data obtained may be modified with historical data to provide usable data.
