20080294017 | IMAGE DATA NORMALIZATION FOR A MONITORING SYSTEM - A method for providing normalized physiological monitoring data of an individual with a measure of the quality of the normalization, including providing a reference feature based on a physiological attribute of the individual for which an attribute value can be determined; unobtrusively capturing physiological monitoring data for the individual during a series of capture events and determining the capture conditions present during each capture event; detecting the presence of the reference feature in the series of captured physiological monitoring data and determining associated attribute values for each capture event; normalizing the captured physiological monitoring data from each capture event according to differences in the attribute values associated with each event and previously calculated attribute values; and calculating normalization confidence values for the individual at the series of capture events, based on capture conditions, normalization transforms, or semantic data, wherein the confidence values statistically measure the quality of the normalization. | 11-27-2008 |
20080297027 | LAMP WITH ADJUSTABLE COLOR - A white-light electro-luminescent lamp having an adjustable spectral power distribution, including a first light-emitting element which emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A second light-emitting element emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A controller modulates the integrated spectral power of the light produced by the first and the second light-emitting elements such that the spectral power distribution of the light formed by combining the light produced by the modulated first and second light-emitting elements is substantially equal to a CIE standard daylight spectral power distribution for correlated color temperatures between 4000K-9500K. | 12-04-2008 |
20100002145 | ADAPTIVE OPTIMIZATION OF A VIDEO SIGNAL - 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. | 01-07-2010 |
20100008426 | METHOD, APPARATUS AND SYSTEM FOR CONVERGING IMAGES ENCODED USING DIFFERENT STANDARDS - 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. | 01-14-2010 |
20100149207 | GRAYSCALE CHARACTERISTIC FOR COLOR DISPLAY DEVICE - An original reference grayscale characteristic for a display panel is created by modifying the sRGB reference grayscale characteristic for the display panel. The changes selectively vary the relative luminances and contrasts of certain regions of the sRGB reference grayscale characteristic. The display device code values for the original reference grayscale characteristic comprise a substantially constant chromaticity corresponding to a particular CIE standard illuminant between D70 and D85 throughout the entire grayscale characteristic. A portion of the display device code values in the original reference grayscale characteristic are changed to provide a taper to a black chromaticity of the display panel in the lower portion of the grayscale characteristic. | 06-17-2010 |
20100156956 | GRAYSCALE CHARACTERISTIC FOR NON-CRT DISPLAYS - 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. | 06-24-2010 |
