This paper puts forward three basic nets for the frequency screen.Based on the picture field pattern,images have been modulated frequently.In order to improve reproduction quality and to gain real frequency effection,tone value matrix and detail position matrix responding to field patterns were advanced.The frequency images will be produced by means of their logic calculations.
