摘要： In accordance with the teachings of the present invention, a system and method for local value adjustment are provided. In one embodiment, the method includes identifying a hue, saturation, and brightness value for each pixel of an image, determining whether the hue and saturation for each pixel fall within a first predetermined set of hue and saturation combinations, determining whether the brightness value for each pixel of the image falls within a predetermined set of brightness values, and selectively applying a gain to the saturation of each pixel based upon the determination of whether the hue and saturation value of the pixel falls within the first predetermined set of hue and saturation combinations and the determination of whether the brightness value of the pixel falls within the predetermined set of brightness values. The method further comprises decimating the image into multiple localized regions, determining a mean brightness value for each localized region, determining whether the hue and saturation for each pixel fall within a second predetermined set of hue and saturation combinations, and selectively increasing the perceived contrast of the image around the mean brightness value for each localized region by applying a transfer function to each pixel of the image based upon the determination of whether the hue and saturation of the pixel fall within the second predetermined set of hue and saturation combinations.

摘要： Methods for improving video images by making real-time gamma correction adjustments to such images are described. More particularly, gamma correction adjustments may be optimized for each individual frame of a video image by first segregating the pixels of an image according to brightness. The segregated pixels may then be used in computing weighting calculations, which modify the transfer functions used for image display. In some embodiments, the video signal may be conditioned between the standard gamma curve and the S-shaped gamma curve used in mapping video signal input to intensity output. In this manner, frame-to-frame gamma correction adjustments can be made, thereby optimizing the resulting image. Related systems for making frame-to-frame gamma correction adjustments are also described.

A polyphase finite impulse response filter is centered on a particular input pixel based on the count value. An output pixel is generated using the polyphase finite response filter on a particular input pixel based on the count value and output pixels are outputted.

摘要： A method and system for performing spatial temporal multiplexing using a multi-threshold mask. A mask generator (404) outputs a threshold value for each pixel of a display. The mask generator typically creates a blue noise mask for a given pixel array that is replicated over the face of the entire display. The blue noise mask generator (404) typically is implemented as a memory lookup table. An index generator (402) provides an offset into the memory lookup table that allows the table to be shifted from time to time. The output of the blue noise mask generator (404), which may be the threshold value itself or a signal representing which threshold is being used, is an input to a selective inverter (406). The selective inverter (406) provides the option of inverting the blue noise mask. To reduce artifacts, the mask is periodically shifted and/or inverted. The value from the mask generator (404), whether inverted or not, is compared to the LSBs of the input data word to yield the fractional bit values. The data adjust block (410) receives the LSBs of the input data word and apportions the intensity between the various fractional bits and perhaps one or more binary bit. Allocating the data between the fractional and binary bits allows the gradual feathering in of each more significant bit as the image intensity word increases.

摘要： A method for film reconstruction includes identifying motion tear artifacts within a plurality of video fields of a stream of video fields. The motion tear artifacts identified by analyzing the video fields using fuzzy logic. The method also includes comparing the analysis of one video field to the analysis of an immediately preceding video field to determine whether there is a relatively high level of motion tear artifacts within the video field or a relatively low level of motion tear artifacts within the video field. The method further includes identifying a pattern of temporal periodicity for the comparisons. The method also includes determining the cadence of the stream of video fields based on the pattern of temporal periodicity.

摘要： According to one embodiment, a method for compensating for inadequate bit resolution in a light processing system includes receiving a plurality of values each indicative of an intensity level for a pixel to be displayed. Each of the values is represented by a plurality of bits of data. The method also includes determining a quantization step size for the plurality of bits of data. For at least one particular pixel of the pixels, a set of consecutive pixels including the particular pixel is selected. The method also includes determining a difference between the value associated with the particular pixel in the set and each value associated with the other pixels in the set, and also determining that all of the determined differences are less than or equal to the quantization step size. In response, a filtered value for the particular pixel in the set is generated based at least on some of the pixels in the set in addition to the particular pixel.
