Abstract: An imaging and display apparatus for passive displays evaluates the illumination of an input scene and incorporates data representative of such input scene within a transfer media. The transfer media may be a storage medium storing image data, illumination data and gamma information for delivery to a passive display system. The data controls the optical characteristics of the illumination source for the passive display and the gamma and tends to minimize energy requirements, to maximize contrast or shades of gray in the displayed image, and to optimize light source operation for color fidelity. The data provided the media and/or display as a video signal, modulated video signal, s-video signal, digital signal, or other signal that can be used by a passive display system to display images.

Abstract: Method and apparatus for preparing and displaying images uses image characteristics of an area of interest of images to optimize or otherwise determine image characteristics of the entire image to be displayed. The area of interest information may be used in computing a System Synchronized Backlight Control (“SSBC”) profile for the area of interest, and the SSBC profile may be used to adjust the image signal to provide an image in which the image characteristics, e.g., are optimized for the image at the area of interest. The image characteristics and/or SSBC profile information may be provided as metadata included in a video signal data stream. The area of interest may be selected where the image is obtained, where the image is shown or elsewhere, e.g., in an image storage device, image player, etc.

Abstract: A display system, method and backlight unit for use with a display. The backlight unit includes a first light source and a second light source, wherein the first light source and the second light source are controllable independently of each other. The sum of light produced by the light sources illuminates the display to achieve illumination brightness capability of a higher intensity capable single light source. Changes in spectral characteristics and/or brightness characteristics due to aging or the like may be compensated. The first light source may provide a base line illumination level for the display and the second light source may be modulated to dynamically increase contrast and/or contrast ratio characteristics of the image being shown on the display to a viewer.
