A vertical deflection waveform generating apparatus is provided to have a memory in which a function of a vertical deflection waveform is previously stored. The function is a function with an order of horizontal scanning lines in which linearity of a raster is corrected as a parameter. The vertical deflection waveform generating apparatus generates a vertical deflection waveform by a digital signal processing circuit substituting a scanning order of the next scanning line in the parameter of the function, and sequentially outputting vertical deflection voltage at each time of detection of a horizontal synchronizing signal. Further, in order to reduce raster moiré, timing for generating the vertical deflection waveform is offset for each frame. |
