20110193895 | High Dynamic Range Display with Rear Modulator Control - Embodiments of the invention relate generally to computer-based image processing, and more particularly, to systems, computer-readable mediums, methods, and apparatuses to operate a rear modulator in a high dynamic range display to, among other things, characterize input images into pixel characteristics which may be data-reduced representations of a group of pixels corresponding to the input image, and to relate a modulation value intensity image to a weighted combination of the pixel characteristics. The modulation value intensity image may be used to derive a rear modulator drive signal, which, turn, may be configured to control one or more modulating elements to generate a low resolution image of the input image at the rear modulator. | 08-11-2011 |
20110193896 | Backlight Simulation at Reduced Resolutions to Determine Spatial Modulation of Light for High Dynamic Range Images - Embodiments of the invention relate generally to generating images with an enhanced range of brightness levels, and more particularly, to facilitating high dynamic range imaging by adjusting pixel data and/or using predicted values of luminance, for example, at different resolutions. In at least one embodiment, a method generates an image with an enhanced range of brightness levels. The method can include accessing a model of backlight that includes data representing values of luminance for a number of first samples. The method also can include inverting the values of luminance, as well as upsampling inverted values of luminance to determine upsampled values of luminance. Further, the method can include scaling pixel data for a number of second samples by the upsampled values of luminance to control a modulator to generate an image. | 08-11-2011 |
20120120096 | Image Control for Displays - Displays such as televisions, computer monitors, and the like may boost ( | 05-17-2012 |
20120315011 | Video Delivery and Control by Overwriting Video Data - Systems, apparatus and methods are provided for generating, delivering, processing and displaying video data to preserve the video creator's creative intent. Metadata which may be used to guide the processing and display of the video data is dynamically generated and embedded in the video data throughout a video delivery pipeline. The metadata may be written in chrominance data for black video frames, black mattes or bars framing an image, and/or in the other image areas for which luminance values are zero or below a threshold value. | 12-13-2012 |
20130050245 | Gamut Compression for Video Display Devices - Apparatus and methods are provided to map out-of-gamut points to in-gamut points. Embodiments transform image data for presentation on a display or medium having a gamut different from that of the image data. Different mapping algorithms may be applied based in part on luminance of the points being mapped. Embodiments apply a reduced dataset representing a gamut boundary. Irregular gamuts may be accommodated | 02-28-2013 |
20130162666 | Data Transmission Using Out-Of-Gamut Color Coordinates - Methods for transmitting additional information together with image data involve replacing pixel values to take in-gamut points to out-of-gamut points. The additional information may constitute metadata describing the image data and/or useful for controlling display and/or processing of the image data; watermark information; or other information. In some embodiments the image data is restored to its original form after extraction of the additional information. | 06-27-2013 |
20130235072 | CONTENT METADATA ENHANCEMENT OF HIGH DYNAMIC RANGE IMAGES - Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced. | 09-12-2013 |
20140249979 | ENHANCING THE HANDLING SPEED OF ELECTRONIC FINANCIAL SERVICES MESSAGES - Handling is expedited for electronic financial service messages, particularly those destined for an exchange | 09-04-2014 |
20140253609 | METHODS AND APPARATUS FOR BACKLIGHTING DUAL MODULATION DISPLAY DEVICES - Methods and apparatus are provided for backlighting a dual modulation display device. Each type of light source comprises a multi-primary light source having two or more primary color light emitters having different primary color characteristics from corresponding primary color emitters of other types of light source. Methods may comprise receiving illumination target values for a plurality of locations on the front modulator corresponding to the plurality of light sources, each of the locations on the front modulator configured to be illuminated by two or more of the plurality of light sources, determining primary color drive values source based on the primary color characteristics for that primary color and the illumination target value for the location corresponding to that light source, and driving the primary color light emitters or each type of light source based on the primary color drive values. | 09-11-2014 |
20140333660 | MAPPING FOR DISPLAY EMULATION BASED ON IMAGE CHARACTERISTICS - An emulator yields modified image data that predicts the appearance of image content on a target display. The emulator generates modified image data based in part on the image content. The emulator may perform a transformation in which one or more parameters representative of features such as black level and/or white level of the target display are functions of image statistics for the image content. | 11-13-2014 |
