LIGHT TRANSMISSION FILTER, IMAGE OUTPUT DEVICE USING THE SAME AND PARALLEL ANALOGUE OPERATIONAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light transmission filter capable of reducing a brightness distribution in an image in a visible light region and producing a clear image in which halation is suppressed. SOLUTION: The light transmission filter is constituted by two-dimensionally arranging substances whose transmittances are changed respectively when light of first prescribed wavelength and light of second prescribed wavelength having different wavelengths from each other are made incident thereon, and light of third prescribed wavelength different from the first prescribed wavelength and the second prescribed wavelength is made incident as two-dimensional image light.
