Abstract
An automatic process controller and method for automatically controlling in real time the formation of an object having boundaries which change with time. A TV camera provides a video image of the object. An interface circuit detects first and second boundaries of the object by analyzing the analog video signal and generates first and second digital numbers corresponding to the first and second boundaries. A programmable digital processor determines the maximum difference between the first and second digital numbers, compares that difference with a target object size and produces a control signal based on the comparison for controlling the continued formation of the object.
