摘要： A video signal processor for controlling a displayed image on a CRT having a cathode electrode and a grid electrode includes a generator for generating a brightness reference signal, an adder for adding the brightness reference signal to a black level in a blanking period of an input video signal. The added brightness reference signal is applied to the cathode electrode though a current detector for detecting a current of the added brightness reference signal. A current level signal produced from the current detector is used for determining and clamping the peak of a control voltage applied to the grid electrode such that a voltage difference between a peak of the added brightness reference signal and the peak of the control voltage is maintained constant.

摘要： A system for compensating image contour by modulating a scanning velocity in accordance with a video signal is disclosed, in which a mean current dissipated in a driving power amplifier is detected to control a gain of an amplifier in a preceding stage for suppressing the increase of power dissipation in the power amplifier when a video signal having many noises is received. The preceding stage amplifier is provided with a saturation characteristic to enhance the effect of contour compensation at a small amplitude signal and eliminate over compensation of image contour at a large amplitude signal. The combination of the saturation characteristic and the gain control further enhances the effect of suppression of power dissipation.

摘要： An automatic primary color component covergence alignment system for a color television display apparatus is presented whereby an alignment pattern is periodically displayed in peripheral regions of the television screen, in each of the primary colors during respective successive correction intervals, the pattern positioned such as to fall upon photo-sensitive devices disposed at the screen periphery. Adjustment of pattern position is executed during each correction interval, based on position data derived from output signals from the photo-sensitive devices, such as to align the alignment pattern with predetermined reference positions. During each period between these sets of correction intervals, the position data thus derived are held stored and are continuously utilized for controlling the deflection of respective electron beams used in generating the primary colors, to thereby implement automatic convergence alignment adjustment.
