Magnification alteration processing method which accords with types of image data and image processing apparatus which uses the method

摘要

A device for outputting video signal includes a magnification alteration processing section that alters the magnification of image data expanded in frame memory in such a manner that the number of pixels in the frame memory and the number of pixels of the display area of a display section are equal. The device further includes a control section for deciding whether or not the magnification alteration processing of the image data by the magnification alteration processing section is to be executed when the image data is being converted into video signals.
