Brightness value (luminosity) is to shoot an area of 25cm2 center of the display by a camera to obtain a luminance value of the pixel by adding the RGB color values of each pixel of the image. Brightness value used for the data using the average value divided by parametric by adding the pixel intensity value of the entire region of interest. I was using a Toshiba Regza42Z8 is Henhikari-shiki 3D display in this experiment.
