Abstract: A method of producing a color image comprising providing input image data from an image source such as a camera; generating an at least three-dimensional look-up table of values of input colors and output colors, wherein the values in the lookup table convert the input image color data to output image color data in an image rendering unit; loading the at least three-dimensional look-up table into an image color rendering controller; loading the input image data into the imaging color rendering controller; processing the input image data through the at least three-dimensional look-up table to produce output color values stored at the addresses in the at least three-dimensional look-up table; and outputting the output color values to the image rendering unit to produce an output image that is perceived to have at least one of enhanced brightness, enhanced contrast, or enhanced colorfulness compared to the input image.

Abstract: A block adaptive linear predictive coding method for encoding a signal having multi-dimensional correlation, such as an image signal as improved by employing multi-dimensional blocks of error signals for making the prediction. As a preferred mode, two statistical quantities are employed to select a quantizer from a set of minimum square error two-variable quantizers based on probability models of statistical quantities.

Abstract: A digital halftone image is produced by providing a binary bit image pattern having a minimum visual noise for each density level in the image, and the binary bit patterns being correlated in a manner that reduces visual noise resulting from transitions between patterns. The patterns are addressed by pixel density and x,y location to produce a halftone image. The patterns are generated by employing a stochastic minimization technique with a constraint to insure correlation between patterns.

Abstract: A circuit for detecting the discharge level of a long life battery, such as a lithium battery, in which the battery is periodically subjected to an increased load for short durations of time. The periodic increases in load allows the end of battery life to be predicted and detected prior to the time the battery is fully depleted. Forecasting the end of battery life ensures that the battery will have sufficient energy to reliably operate the discharge level detection circuitry before the battery is fully depleted.

Abstract: Each member of a set of transform representative data structures (such as look-up tables (LUTs), each representing an N TO M-dimensional transform), is stored in compressed form in a storage device included in, or which is otherwise accessible to, an image processing device or system. Each stored transform representative data structure may then, according to one embodiment of the invention, be selectively attached to image data being processed by the image processing device or system. According to a further aspect of the invention, image data, having compressed transform representative data attached thereto, may be processed utilizing methods and apparatus operative to detach, decompress and apply the transform represented by the decompressed transform representative data, to a decompressed version of the image data. The result of the aforementioned process is for image data to be transformed according to a transform specified by information previously attached to the image data.

Abstract: A method for reducing noise in an image signal includes the steps of sampling an image to produce a sampled image signal representing pixel amplitude values, the sampled image signal including noise having a known probabilty density function (pdf); digitizing the pixel amplitude values to produce a digital image; forming an image difference signal from the digital image signal by taking the difference between successive pixel amplitude values; processing the image difference signal in digital processing means including a digital MAP filter incorporating a MAP estimator for estimating the signal and noise pdf's of a signal having a Laplacian pdf degraded by noise having a know pdf, to produce a MAP filtered image difference signal; and recovering a restored digital image signal from the MAP filtered image difference signal by summing successive amplitude difference values in the MAP filtered image difference signal. Since the pdf of the differential image signal is more nearly stationary than the image signal itself, a MAP estimator based on a differential image signal provides a more reliable estimate of the original signal statistics, even though the statistics of original signal may vary widely.
