Abstract:
1. An electronic correction method for correcting a plurality of optical anomalies associated with image capture and image display of an optical image processed through optical capture and display components having physical and geometrical characteristics, by compensation of digital image pixel data associated with the optical image, said method comprising: identifying and representing several optical anomalies associated with the physical and geometrical characteristics of the optical capture and display components as an optical anomaly grid dataset; identifying and representing distortion free behavior of the optical capture and display components as an ideal grid dataset; for the optical anomalies comparing the optical anomaly grid dataset with the ideal grid dataset and determining an anomaly correcting transformation dataset by performing an inverse spatial transform from the ideal grid dataset to the anomaly transform such that functional composition of the anomaly correction transformation with the optical anomaly grid dataset reduces to the ideal grid dataset; representing the anomaly correcting transformation via surface based functionals; applying the surface based functionals to the image pixel data to produce corrected image pixel data which when viewed is free of the optical anomaly.
