ABSTRACT:
A method of scanning frames of cinematographic film to generate digital values of pixels constituting images on the film frames is provided in which pixels corresponding to defects on the film are identified and the values of such pixels are adjusted to compensate for the defects, the identification of the pixels corresponding to defects on the film being carried out by identifying pixels whose value is beyond a predetermined threshold.A method of correcting for flicker in digital images obtained by scanning cinematographic film is also provided. This method comprises the steps of identifying frames in which flicker is present; identifying relatively bright regions in those frames whose brightness is above a predetermined level, and correcting digital pixels in those relatively bright regions so as to compensate for the effect of flicker.
