    摘要: The size of an image displayed on a tube surface is varied while maintaining the aspect ratio thereof at a constant. First, if there is information of an arbitrary horizontal-size variable parameter and a vertical-size variable parameter because of parameters supplied previously by adjustments, the horizontal/vertical size of a raster formed at that time can be obtained, and the aspect ratio thereof can be obtained on the basis of the horizontal/vertical size of the raster. Then, during a zoom mode, the vertical-size variable parameter corresponding to the updated horizontal-size variable parameter is computed so that the detected aspect ratio becomes constant, and the raster size is changed in accordance with these values.
