Flare compensation circuit for television |
摘要 |
A flare or scattered light compensation circuit for television, wherein a controllable signal difference amplifier is present to a first input of which a picture signal, affected by flare or scattered light, is applied, a compensation signal obtained by signal integration being applied to a second input. The gain factor of the amplifier is controlled substantially proportional to the quotient of the peak-peak value of the picture signal and of the difference value of the said peak-peak value and the value of the compensation signal.
