PROJECTED VIDEO ADJUSTING DEVICE, ADJUSTING SYSTEM AND ADJUSTING METHOD

摘要

PPROBLEM TO BE SOLVED: To easily and surely adjust the luminance and the chromaticity of a projected video projected from a projector. PSOLUTION: The projected video adjusting device is equipped with a dimming filter 11 decreasing the quantity of projected light projected from the projector 2 projecting the video onto a projection surface, a condensing lens 12 condensing the projected light passing through the filter 11, a rod lens 13 uniformizing the luminance of the projected light passing through the lens 12, and a luminance sensor 14 for detecting the luminance of the projected light passing through the rod lens 13.
