Abstract
An image display apparatus capable of displaying an image on a plane of projection by beam raster scanning associated with resonant oscillation in a horizontal scanning direction (the main scanning direction), includes a resonance-point detector for detecting a mechanical resonant frequency in the horizontal scanning direction. Out of frequencies that are multiples of a vertical synchronizing frequency in image display, for example a frequency nearest to the mechanical resonant frequency detected in the resonance-point detector is determined as a horizontal scanning frequency of the raster scanning. The image display apparatus can thus provide a stable image display with ease.
