Title: Video signal processor
Inventor: OOTA HARUO
IPC: H04N5/21
Filed: 1985-11-26
Abstract: PURPOSE:To reduce noise of large amplitude superimposed on an edge part of an image by referring to a signal amplitude in the vicinity of a vertical frequency of an input signal as well as the signal amplitude of a high frequency of a horizontal frequency and suppressing the signal. CONSTITUTION:The input signal inputted from an input terminal 1 and the output signal of a coefficient circuit 4 are added by an arithmetic circuit 102 to sample the signal in the vicinity of the vertical frequency 0(cy/ph), further, the high frequency component of the horizontal frequency is obtained by a high-pass filter 103 from this signal, thereby,a variable non-linear shape input and output circuit 101 is controlled. When the amplitude of a control signal is smaller than a reference value, the variable non-linear shape input and output circuit 101 is bypassed, it is operated as a comb-line filter, and when the amplitude of the control signal corresponding to a longitudinal line on a screen is larger than the reference value, the noise of the large amplitude superimposed on the longitudinal edge part on the screen is reduced by the variable non-linear shape input and output circuit 101.
