ABSTRACT:
Vector (i.e., line) drawings represent the "intelligence" content of images.
A method is disclosed for the gathering of intelligence and the generation of vectors on the screen of a CRT without the usual problems associated with cost and performance.
The Vector Generator itself uses pairs of digital-to-analog converters with a common analog output. This technique is referred to as interpolation. Careful shaping of the complementary reference voltages of the digital-to-analog converters results in constant velocity, transient-free vectors with starting and end points that are accurately controlled. Cumulative (i.e., closure) errors are entirely absent.
