By means of control system for the load control of the ink volume signal

摘要

A system for detecting overload conditions of a chrominance signal in which the chrominance signal is compared to a predetermined maximum desired amplitude value. Occurrences of the chrominance signal exceeding the predetermined amplitude are considered to be overload conditions only if the duration of the particular occurrence continues for an interval determined by the noise content of the chrominance signal. The average value of the chrominance signal over the internal is calculated to represent the overload signal.
