METHOD FOR REGULATING DIGITAL DYNAMIC FOCUS OF A TELEVISION SET

摘要

PURPOSE: A method for regulating digital dynamic focus of a television set, is provided to output a pattern preset for focus regulation in each regulation point preset on a screen in order to make a regulator confirm a focus regulation state of each regulation point, and to generate a focus signal of an entire screen on the basis of values of regulation points by a digital interpolation method to generate a digital focus signal, so that an optimum focus state can be maintained. CONSTITUTION: A pattern preset for focus regulation in each regulation point preset on a screen, to make a regulator confirm a focus regulation state of each regulation point. Regulation values of each regulation point are inputted by an operation of a regulation apparatus of the regulator. A focus value of entire screen is generated by a digital interpolation method by using the regulation values of each regulation point. The generated focus value of the entire screen are converted to analog to generate a dynamic focus waveform.
