Abstract
A signal generating apparatus comprises: a scanning-line number detector (2) for detecting the number of scanning lines with receipt of a sync signal; a convergence memory (3) for storing convergence correction data; an on-screen display memory (5) for storing on-screen display data; an interpolator (4) for performing vertical interpolation of output data derived from the memories (3, 5) according to the detection signal derived from the scanning-line number detector (2); and a frame memory (6) for successively reading data elements corresponding to the individual scanning lines interpolated by the interpolator (4). The apparatus detects the number of scanning lines and generates a correction signal and a character signal through vertical processing of convergence correction data and on-screen character data.
