Abstract
An analysis method for cinematographic film uses a film scanner for converting the images of the film into video images, the film scanner having a calibration mode providing a standardized video reproduction of films and a manual mode allowing the operator to adjust the film scanner for improving the visual quality of the video images it produces. The method comprises the steps of: a) filming a reference surface under desired lighting conditions to produce a film portion; b) using the film scanner in calibration mode to convert the film portion into video images; c) measuring the mean luminance and chrominance values of a portion of the reference surface in the video images produced in the calibration mode; d) using the film scanner in the manual mode to convert the film portion into video images with desired luminance and chrominance adjustments; e) measuring the mean luminance and chrominance values of a portion of the reference surface in the video images produced in the manual mode; and f) providing information on the mean values obtained in the manual mode relative to the mean values obtained in the calibration mode.
