摘要:
A method and system for determining correction information for the universal display of an original video sequence on a plurality of displays includes correcting an original video sequence using a first display, storing correction information related to the correction of the original video sequence using the first display, correcting the original video sequence using a different display, and determining and storing the differences between the correction information related to the correction of the original video sequence using the first display and using a particular, different display. Subsequently and prior to the display of the original video sequence, the original video sequence is corrected using a combination of the stored correction information related to the correction of the original video sequence using the first display and the respective determined differences, if any, related to a particular, different display on which the original video sequence is now to be displayed.

摘要:
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.
摘要:
A system for scanning cinematographic film so as to produce digital images corresponding to the images on frames of the film is provided. The system includes means for scanning the film, means for displaying the digital images obtained by scanning the film, and image processing means. The image processing means includes means for adjusting the appearance attributes of the digital images obtained and further includes (a) means for displaying the output signal level versus time in graphical form for the images obtained, and/or (b) means for displaying the luminance, chrominance and saturation of the images obtained in graphical form on polar axes.
