Image processing for digital cinema
Abstract
A method for processing a sequence of digital image signals in order to match the appearance of a particular display medium, such as a motion picture print film, includes the steps of (a) converting the digital image signals into signal values in an analytical dye amount space where the signal values are proportional to a dye set corresponding to the particular medium; and (b) converting the signal values in analytical dye amount space into output values suitable for a display device, such as a digital projector. Moreover, the signal values in analytical dye amount space may be corrected for viewing conditions, such as printing flare, gamma, contrast ratio or neutrality.
