Abstract
In correction waveform data generating apparatus for digital convergence or digital focusing in a color television receiver, the adjustment data for all adjustment points including the region of blanking intervals is controlled from the adjustment data for a relatively small number of representative adjustment points on the image screen. Data for the representative points is automatically interpolated to generate uniform correction waveform data for the entire image screen. Basic correction waveform data is stored for each representative adjustment point and is repeatedly added to and/or subtracted from on the basis of adjustment instructions at the respective adjustment points, so that data adjustment and waveform correction are achieved.
