    In this presentation, find out how a photographic-grade digital camera can be deployed for quality assurance (QA) of both color and grayscale LCDs.

    A team from Kyushu University in Japan converted the RGB signals gathered by a commercially available digital camera into grayscale signals that correspond to the luminance of the LCDs, according to the researchers. Weighting factors for each color compensated for the different spectral sensitivities of cameras.

    "Our method could be used for routine ... QA of LCDs in hospitals," said presenter Shogo Tokurei.

    Tokurei noted that the unprocessed RGB signals of photographic-grade digital cameras depend on the spectral sensitivity of each camera. Therefore, such cameras should not be directly applied to quantitative assessment of the luminance of LCDs without being calibrated, especially when used in color LCDs, he said.
