  • Publication number: 20240422449
    Abstract: Dynamic systems and methods for fixed noise pattern calibrations and image corrections are provided. Imaging devices may be calibrated via the system by adjusting an imaging sensor exposure to acquire one or more black images. A global average pixel value is calculated to accumulate pixel values per column of the acquired image. The calculated global average pixel value is then saved as offset imaging data. An average pixel value per column of the imaging data based on the accumulated pixel values may also be calculated, and stored as offset imaging data. A correction matrix may be recomposed based on the offset imaging data and used for calibrating the imaging sensor, and for creating corrected images in or near real time.
