摘要： A video signal includes a plurality of frames of image data. A single frame of image data or multiple frames of image data, one or more reduced resolution frames, or a portion or portions of one or more frames or reduced resolution frames can be analyzed to determine initial statistics. One or more correction operations are then performed on the initial statistics to generate initial correction values. The one or more correction operations include a balance correction operation, a flare correction operation, and a tonal correction operation. After the initial correction values are determined, a temporal filter is applied to the initial correction values to generate final correction values. Optimized image data is then generated by applying the final correction values to image data in one or more frames.

摘要： Color negative photographic films having red, green and blue color sensitive records, wherein the ratio of the toe area contrast to the mid-scale contrast for each of the red, green and blue color records is less than or equal to 0.80, and either at least two color records having a toe-area contrast less than or equal to 0.42 or a mid-scale contrast less than or equal to 0.55, or the film having a speed rating of ISO 200 or greater. The mid-scale contrast for a color record is defined as the slope of a straight line connecting a point C and and a point D on the characteristic curve of Status M density versus log Exposure for the color record, where points C and D are located by defining a point A on the characteristic curve at a density level 0.1 above minimum density, a point B is located on the characteristic curve at an exposure value +1.0 Log Exposure beyond point A, and points C and D are located at exposure values -0.45 log Exposure and +0.45 log Exposure with respect to point B, respectively. The toe-area contrast is the slope of a straight line connecting a point E and a point F on the characteristic curve, where point E is located at (mid-scale contrast)/6 density units above minimum density, and point F is located at 0.3 log Exposure higher in exposure on the characteristic curve than point E. Use of such a color negative films are particularly advantageous in making telecine transfers.

摘要： A method for transforming an image expressed in terms of a first image encoding to a second image encoding, includes converting a set of original scene exposure-factor values into corresponding first and second image encoding values. A transform is then derived between the first image encoding values and the second image encoding values. The transform is then applied to an image encoded in said first image encoding. Examples of different encoding that can be transformed include Rec. 709, sRGB and other known image encoding standards. A system for performing such transformations as well as an electronic device that is capable of performing such transformations are also disclosed.

摘要： A method for color density correction in a printing system that includes a linehead, with one or more printheads, that jets ink onto a moving print media and an integrated imaging system that captures images of content printed on the moving print media is provided. One or more pixel data values and a measured density value trace for a printed test block are produced by scanning the test block and averaging pixel data in a print media transport direction. A color and a density of the ink in the printed test block are determined using the pixel data values. The measured density value trace is compared with a respective reference density value. It is determined whether there is a difference between the measured density value trace and a reference density value is determined. If there is a difference, ink laydown for the printhead is adjusted based on the difference.

摘要： Reference calibration patches produced by a sequence of exposures on a photographic element, the photographic element exhibiting linear defects in a predominant direction, are arranged in a two dimensional array and exposures are assigned to the reference calibration patches in the array such that nearest neighbors in the predominant direction are not nearest neighbors in the exposure sequence, whereby the effects of a linear defect are reduced; and the maximum number of steps in the exposure sequence between a reference calibration patch and that of its nearest neighbors in any direction is less than a predetermined number, whereby the effects of flare are reduced.
