<P>PROBLEM TO BE SOLVED: To apply a screen whose display is updated at all times in a main body display device to an external display device without delay. <P>SOLUTION: For displaying the same screen on a main body display device which is fixedly installed in a main body and an external display device which is constituted independently of the main body, images such as characters and/or figures to be displayed on the main body display device are created with lower drawing quality than drawing quality of images such as characters and/or figures to be displayed on the external display device. That is, for displaying the same screen, the main body display device displays a screen in which images such as characters and/or figures are created with lower drawing quality, and the external display device displays a screen in which images such as characters and/or figures are created with better quality than the lower drawing quality. Accordingly, on the one hand the main body display device displays a screen although it is of low quality, but on the other hand the external display device displays a screen in such a manner that images such as characters and/or figures smoothly change without intermittent movements. <P>COPYRIGHT: (C)2013,JPO&INPIT |
