Video display with emission control |
摘要 |
<p>Unintentional emissions are controlled responsive to the spectral content of the display signal. A video display apparatus comprises a cathode ray tube responsive to a video signal. A processor (50) controls a bandwidth of the video signal (v,g,b) coupled to the cathode ray tube in response to an emission control signal (CONT. 1). A generating means (20) is coupled to the processor (50) for generating the emission control signal (Ve) responsive to a component of the video signal (Y). <IMAGE></p> |
