Abstract

The present invention relates to a digital convergence adjusting device and method that enables a user to easily and quickly adjust a deflection signal by preventing flickering and shaking of a screen when changing a shape of a deflection signal applied to a deflection yoke of a television receiver. It is about. To this end, the digital convergence adjusting apparatus and method are provided for switching a standard image data to be transmitted from the pattern generator to the image processing unit of the television receiver, and a pattern generator for generating standard image data for screen adjustment to be supplied to the image processing unit of the television receiver. Converting switch, an erasable memory storing deflection waveform data for deflection control, an address generator for generating sequential address signals required for the pattern generator and the memory, and deflection waveform data read from the memory into an analog signal And a D-A converter for supplying the converted deflection signal to the deflection yoke of the television receiver, a keyboard for inputting waveform correction data, and a CPU for controlling the memory and the switching switch. Input the waveform correction data from And convert the deflection waveform data stored in the memory into waveform correction data inputted from the key input means and control the changeover switch so that the Kyojun image data is not transmitted to the image processor of the television receiver.
