Abstract
A video dot intensity balancer for use in a video display system wherein information is represented by a series of logic bits in a video stream corresponding to dots to be displayed on a CRT is disclosed. Logic elements are coupled to the output of a bit generator for comparing adjacent bits and outputting an information-defining signal wherein a single information-defining bit never stands alone. In this manner, apparent intensity imbalances on the video screen are eliminated.
