Claim One:
1. An image display apparatus, comprising: a communication unit, using a processing device, to communicate with a plurality of information processing apparatuses; an image synthesizing unit, using the processing device, to synthesize a multi-segmented screen image data composed of screen images of the plurality of information processing apparatuses based on image data received from each of the plurality of information processing apparatuses through the communication unit; a projection unit to project the multi-segmented screen image data synthesized by the image synthesizing unit as a multi-segmented screen image onto a screen; a functional mode management unit, using the processing device, to control switching between a normal projection mode and a multi-segmented screen operation mode, wherein the functional mode management unit receives an interrupt request from each of the information processing apparatuses when switched to the normal projection mode; an image capture device to capture the multi-segmented screen image displayed on the screen and an image of hand movement of an operator with respect to the multi-segmented screen image when the functional mode management unit switches to the multi-segmented screen operation mode; a designated screen image recognition unit, using the processing device, to detect a hand movement of the operator with respect to the multi-segmented screen image based on the multi-segmented screen image and the image of hand movement of the operator captured by the image capture device, and to recognize a screen image designated as an active-target image in the multi-segmented screen image based on the detected hand movement; and a signal control unit, using the processing device, to transmit a request of image data transmission to an information processing apparatus corresponding to the screen image designated as the active-target image by the designated screen image recognition unit, and not to receive an interrupt request from an information processing apparatus corresponding to a screen image of a non active-target image.
