Abstract

FIELD: TV. SUBSTANCE: in television systems with SECAM color image error in determination of phase angle of signals u and v with color difference reduces thanks to identification of quadrant or sector carrying this signal and to conversion of values u and v into zone of minimal error of pulse modulation. EFFECT: reduced color image error.

Claims (1)

В телевизионных системах с цветным изображением SЕСАМ ошибка при определении фазового угла сигналов U и V с цветовой разностью уменьшается благодаря опознаванию квадранта или сектора, содержащего этот сигнал, а затем - благодаря преобразованию значений U и V в зону минимальной ошибки импульсной модуляции.In television systems with a SECAM color image, the error in determining the phase angle of U and V signals with a color difference is reduced by identifying the quadrant or sector containing this signal, and then by converting the U and V values to the zone of minimal pulse modulation error.
