摘要:
A method of calibrating a flat panel display, comprising the steps of: providing a flat panel display, calibrating the display to establish desired chromaticity and/or luminance for one or more colors of interest at a first reference angle, measuring the chromaticity and/or luminance data for at least one color of interest at a minimum of one additional reference angle distinct from the first reference angle, and selecting a target calibration angle in response to the measured data and calibrating the display to establish desired chromaticity and/or luminance for colors of interest at the selected target calibration angle. The target calibration angle may be selected to deliver optimal display performance as a function of one or more desired viewing angles. These viewing angles can be in the tip direction, turn direction or in a direction that is some combination of tip and turn.

A stand-alone station such as a kiosk (10) includes automated equipment for performing eye examination procedures on a user positioned in the station (11). Information derived from the examination determines possible existence of a correctable medical condition. The station includes a user interface (22) and a fulfillment remedy section (30) that addresses the medical condition, as by fabrication of eyeglasses (32) for correction of refraction error, or by communicating treatments through the user interface to the user for treating such conditions as age-related macula degeneration, Alzheimer's disease, or visual field impairment. The station also includes a payment device (24) allowing the user to directly pay for the procedure and to indirectly pay using identified health insurance coverage.
摘要:
An image file for storing a still digital image and metadata related to the still digital image, the image file including digital image data representing the still digital image, and metadata that categorizes the still digital image as an important digital image, wherein the categorization uses a range of levels and the range of levels includes at least three different integer values.
摘要:
A color display device, comprising: an array of subpixels of at least four different colors, including at least two relatively higher luminous color subpixels and at least two relatively lower luminous color subpixels, wherein the subpixels are arranged into groups forming at least two distinct types of pixels, each pixel type including the two relatively higher luminous color subpixels and at least one of the two relatively lower luminous color subpixels, and wherein the pixel types are arranged in a pattern such that the relative locations of the two relatively higher luminous color subpixels in each pixel is repeated in adjacent pixels, and the relative location of at least one of the two relatively lower luminance color subpixels is not repeated in at least one adjacent pixel. Various embodiments of the invention enable color display devices with improved image display quality, with both the appearance of jagged lines and the appearance of banding reduced simultaneously.
