<P>PROBLEM TO BE SOLVED: To make an external display device display both display data corresponding to a user operation and significant data corresponding to the display data, with respect to compact electronic equipment connectable to a projector. <P>SOLUTION: For example, in a function graphic mode, display setting data for setting the coordinate range of graphic display and a desired graphic formula are input, and when a display part 20 is made to display a function graph screen GF on which a graph corresponding to the graphic formula is drawn, the other screen types (graphic type screen and display setting screen) corresponding to the displayed screen type (function graph screen) are determined according to screen type correspondence data in each operation mode stored in advance. Then, projector transmission data in which the respective screens of not only a function graphic screen GF under current display but also the determined corresponding screen types of graph type screen SF and display setting screen SH are arranged for a projector 30 are generated, and transmitted to the projector 30, and projected and displayed on a screen 37. <P>COPYRIGHT: (C)2011,JPO&INPIT |
