Abstract: TV camera signals to be presented on a TV monitor are processed to remove undesirable shading components. The circuitry is adaptive in that for each input video signal a low frequency component is extracted to obtain a corrective waveform which is subtracted from that input signal or a subsequent input signal to reduce or eliminate the shading component. Further correction may also be made by utilizing the corrective waveform to govern the amplification of the video signal to be displayed.
Abstract translation: 处理要呈现在电视监视器上的电视摄像机信号，以消除不期望的阴影部件。 电路是自适应的，因为对于每个输入视频信号，提取低频分量以获得从该输入信号或后续输入信号中减去的校正波形，以减少或消除阴影分量。 还可以通过利用校正波形来控制要显示的视频信号的放大来进一步校正。

Abstract: Periodic signals, for example sonar returns, to be displayed on a conventional television monitor are sampled and put into storage registers at a first rate. The storage registers are emptied at a second rate and the information is placed onto a video magnetic disk. For each sonar transmission a number of samples of the return signal are placed into, and read out of, the storage registers, during each revolution of the disk, as the return is coming in, to build up a television display signal indicative of the sonar return.
Abstract translation: 将在常规电视监视器上显示的定期信号，例如声纳返回被采样并以第一速率放入存储寄存器中。 存储寄存器以第二速率清空，信息被放置在视频磁盘上。 对于每个声纳传输，当返回进入时，在盘的每次旋转期间，将返回信号的多个样本放置到存储寄存器中并从存储寄存器读出，以建立指示声纳的电视显示信号 返回。
