Title: Television system converter
Inventor: WAKABAYASHI HARUO
IPC: H04N7/00
Filed: 1990-03-30
Abstract: PURPOSE:To improve the sharpness and resolution by applying simplified processing in the direction of time axis so as to suppress loopback noise. CONSTITUTION:A differential signal 26 is fed to a low pass filter 27 and only components less than 4.05MHz where no loopback component exists between frames are extracted as shown in spectrum in Figure. However, the horizontal frequency is that for the high definition television system, the sample rate is lowered by a time axis converter 15, and the frequency is equivalent to nearly 3.60MHz in the case of the frequency of the standard television system. Thus, a spectrum of a luminance signal 21 in the case of conversion to the frequency of the standard television system is as shown in Figure (a). As a result, the spectrum of an output signal 28 of the low pass filter 27 is as shown in Figure (c) and no loopback component between frames is included in the spectrum. Thus, the signal 28 is used as a signal representing the movement accurately and the sharpness and resolution are improved.
