Abstract

PURPOSE:To prevent the dispersion due to measuring personnel such as visual measurements, by measuring the luminance of the boundary having luminance difference with a plurality of photodetectors arranged in a given interval. CONSTITUTION:A pattern generator 18 produces the video pattern divided into two in white and black on the screen 12 of a video display device. Further, a luminance measuring device 19 is located at the boundary of white and black of video pattern, and the video pattern is formed at the position of a plurality of photodetectors 15 with a lens 6 to measure the luminance of the video pattern. Further, the output of photodetectors is compared at the intermediate luminance level between white and black levels at a discriminator 16, and the result is displayed on a display element 17. Thus, the amount of video fluctuation can be measured by counting the number of displayed display elements 17.
