  • Patent number: 8169607
    Abstract: A processing unit obtains a first spectrum detected in a first detection area and a first signal intensity detected in a second detection area after the light entering the housing is cut off, and then calculates a first correction spectrum by subtracting a first correction value calculated based on the first signal intensity from each component value of the first spectrum. The processing unit obtains a second spectrum detected in the first detection area and a second signal intensity detected in the second detection area while a cut-off portion is opened, and then calculates a second correction spectrum by subtracting a second correction value calculated based on the second signal intensity from each component value of the second spectrum. The processing unit calculates an output spectrum representing a measurement result by subtracting a corresponding component value of the first correction spectrum from each component value of the second correction spectrum.

    Abstract: A motion picture moving on a display screen 21 of a display device 2 to be evaluated is captured a plurality of times by means of a galvano camera 3a. The captured data include locations of the moving picture in the moving direction on the display device 2 to be evaluated and data on luminance of the display device at the respective time points of the locations. Based on these data, a motion picture eye-tracking simulation is performed, where an integration along the eye tracking direction over an integral multiple of 1 frame time is performed to obtain a motion picture response curve of the display device 2 to be evaluated. Evaluations of motion picture characteristics and motion picture blur can be made based on the motion picture response curve.
