摘要： An image processing system includes a frame store, a processing means and a monitor. The frame store stores a sequence of images from a film or video clip that will eventually be transferred to film for viewing in a theater. The image sequence is processed and possibly combined with other clips, resulting in changes to the color balance, intensity and contrast of the output clip. The image processing system, the monitor and the process of eventual transfer to film, have non-linear transfer characteristics, including gamma characteristics. These are combined in a single look-up table in a graphics card, so that images displayed on the monitor have an appearance matching that of the same images when viewed in the theater.

摘要： A method of gamma correction includes selecting lower and upper reference curves corresponding to selected reference gamma values. A gamma correction curve is generated from a corresponding gamma correction value and cross-correlated with the upper and lower reference curves to generate a corresponding set of cross-correlation factors. The set of cross-correlation factors are stored and indexed to the corresponding gamma value. An input value is received for gamma correction with the corresponding gamma value. Data from the upper and lower reference curves indexed by the input value are then operated one with the cross-correlation factors to generate a gamma corrected output value.
