Abstract
We propose a method for evaluating the image quality of color LCD monitors by using the polychromatic modulation transfer function (PMTF). The PMTF is calculated from the values of monochromatic MTFs weighted by the overall spectral response of the system. We also propose a method for simulating the PMTF of a color LCD monitor by using three bar targets with different amplitudes. To obtain the spectral response of the color LCD monitor, the chromaticity (x,y) and luminance are measured with a spectroradiometer. The PMTF measuring system with a 2-D cooled charge coupled- device camera, an objective lens and a translator is used to evaluate the color LCD monitor.
