CONTROL METHOD FOR CONTROLLING SCREEN SAVER FUNCTION, APPARATUS AND SYSTEM ADOPTING THE METHOD

When a TV conference application program is initiated, a software timer is activated. The timer is set to a predetermined period, e.g., 30 seconds, which is shorter than the time when a screen saver image starts to be displayed, e.g., one minute. Every 30 seconds, a pseudo user input event of mouse displacement is generated. Accordingly, the time counter of a screen saver is cleared before the predetermined time when the screen saver image starts to be displayed has elapsed, thereby it is possible to prevent the screen saver image from being displayed during executing the TV conference application program.
