The products of CCD and CMOS photon sensor parts, is used the way of noncontinuity to receive the image, so when screens with some thin line, there will produce some otiose noise. Optical Low
Pass Filter (OLPF) is had the function to eliminate this noise. Different thin line direction should use the rightness OLPF to remove. Also for the different model number of CCD, CMOS photon sensor
parts have some differences on the specification, for compromise the different model number and the low pass effect, so it need to be used various dissimilarity incise angle (such as 45
