To obtain an electronic presentation system which is flexibly adaptive to the state in a lecture and gives a high degree of freedom of a lecturer by providing a touch panel on the screen of an image display device as a terminal for the lecturer and displaying image data in a memory for image display on more than one display devices.

A display controller 9 displays display data, stored in a 1st image memory 7, on a 1st display device 14 for an attendance and controls a mixer 13 to put display data of the 1st image memory 7 and a 2nd image memory 8 one over the other, thereby displaying the resulting display data on a 2nd display device 15 as the terminal for the lecturer. The terminal for the lecturer comprises the 2nd display device 15 and touch panel 16 and image data on the 1st display device 14 can be switched at an arbitrary point of time in the lecture by operating the touch panel 16. Consequently, the lecturer is able to control the display system in addition to contents displayed for the attendance.
