Abstract: A method for two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample. In various embodiments, an improved method and system is provided for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing. The method may include directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; directing a second portion of the light to a colorimeter which produces second tristimulus values; deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values. In many embodiments, the imaging colorimeter system is capable of two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample.

Abstract: Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

Abstract: A method of manufacturing an EL display device having a light emitting part, in which a plurality of pixels are arrayed, and a thin-film transistor array device to control light emission of the light emitting part, includes a luminance measurement step of obtaining luminance data of pixel, with the light emitting part being lit. The luminance measurement step includes a first luminance measurement step and a second luminance measurement step. In the first luminance measurement step, a first imaging apparatus obtains luminance data by measuring light emission of the each pixel. The first apparatus has a resolution corresponding to that of the pixels of the light emitting part. In the second luminance measurement step after the first step, a second imaging apparatus measures light emission of a plurality of the pixels to correct the luminance data of the each pixel obtained in the first luminance measurement step. The second imaging apparatus is lower in resolution than the first imaging apparatus.

Abstract: An LED classification device (21) classifies LEDs, the LEDs each including a combination of an LED element that emits a primary light and a phosphor that, upon excitation by the primary light, emits a secondary light having a longer wavelength than the primary light, the LEDs each emitting a combined light of the primary light and the secondary light, those ones of the LEDs whose primary lights having their chromaticities falling within a predetermined chromaticity range being classified as LEDs for use in a backlight of a liquid crystal display apparatus. A coefficient calculating section (26) and a corrected chromaticity calculating section (27) calculate, for all of the LEDs to be classified, correction values for the chromaticities as obtained on the assumption that the primary lights have traveled through a color filter of the liquid crystal display apparatus, and correct chromaticities by subtracting the correction values from chromaticities obtained for all of the LEDs to be classified, respectively. A chromaticity rank classification section (28) classifies the LEDs according to chromaticity rank on the basis of the corrected chromaticities.
