FIELD: physics, computer engineering.
SUBSTANCE: invention relates to information processing devices. The result is achieved due to that, once the magnification chromatic difference of the optical image forming system is corrected, a first value relating to colouring is obtained before applying an image reconstruction filter. An image reconstruction filter is then applied, said filter preferably not correcting the magnification chromatic difference and being based on a function which indicates aberration of the optical image forming system. A second value associated with colouring is obtained from the image after applying the image reconstruction filter. Correction of the pixel value is performed to correct colouring according to the difference between the first and second values, obtained before and after applying the image reconstruction filter, respectively.
EFFECT: reduced colouring in an image after image reconstruction processing.
