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 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： A method for generating a target display characteristic for a non-CRT display device includes establishing a sequence of luminance-factor values corresponding to original-scene neutrals. The luminance-factor values are converted to corresponding Rec. 709 signal values. The luminance-factor values are then mapped according to a desired system tone reproduction characteristic to corresponding luminous intensity values to be reproduced by the non-CRT television display device. The target display characteristic is generated by relating the corresponding Rec. 709 signal values to corresponding luminous intensity values.

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.
