CONTROL UNIT FOR THE BRIGHTNESS OF VIDEO SIGNALS ON A RASTER SCAN DISPLAY |
摘要 |
<p>A control unit for the brightness of video signals on a raster scan display is provided with a random-access memory. The data stored in each element of this memory determines the brightness of the video signals on the raster scan display at a position corresponding with this element. In response to the video data supplied to the control unit and the brightness data in the random-access memory a logical unit provides new brightness data which overwrites the brightness data in the memory.</p> |
