  • Signal processing filter for an image projection device utilizing an oil film
    Patent number: 4807040
    Abstract: A projection type image display device utilizing an oil film is disclosed, which device comprises a filter having frequency characteristics enabling reduction of the spatial frequency response in the vertical direction for an input signal having a stepwise waveform in the vertical direction to a value under those obtained by using the following formula with respect to the coordinate x of the position of the scanning line in the vertical direction;f(x)=[1+sin (.pi..multidot.x/D.sub.O)]/2where D.sub.O represents the smallest scanning line interval, outside of which adjacent scanning lines have no influences thereon, and filtering the input image signal according to those characteristics.
