摘要： A signal having a maximum amplitude corresponding to a pedestal level of a composite video signal is produced by removing a horizontal synchronizing signal from the composite video signal. An automatic gain control signal is derived from the first mentioned signal in dependence of the peak value thereof to control a high frequency amplifier and or an intermediate frequency amplifier so that the pedestal portion at the maximum amplitude level of the composite video signal is maintained constant. In this way, a stabilized pedestal portion or the black level can be attained, which in turn results in a stabilized contrast.

摘要： The present invention relates to a deflection yoke device which is preferably combined with an in-line type color picture tube having electron guns aligned horizontally. The distribution of magnetic fields is determined in the horizontal direction such that a sharp or strong barrel magnetic field is localized on the side of the neck portion whereas an extremely sharp pincushion magnetic field is localized on the side of the funnel portion and at the same time, an intensely sharp pincushion magnetic field is distributed between the funnel portion and the neck portion. The central electron beam is deflected more at a greater angle than side electron beams so as to land outside the side electron beams.
