Image Projection System, Terminal Apparatus, and Computer-Readable Recording Medium Recording Program

A terminal apparatus comprising:

• an application program control unit that controls a predetermined application program;
• an image generation unit that generates image data based on the application program controlled by the application program control unit;
• a display control unit that controls display of an image based on the image data generated by the image generation unit and controls termination of the display;
• a predetermined region image transmission unit that, when positions of the image based on the image data generated by the image generation unit is located in the predetermined display region, partially or entirely transmits the image data of the image to the image projection apparatus via the communication path, in order that an image projection apparatus acquiring a plurality of pieces of image data from a plurality of terminal apparatuses via a communication path and projecting images based on the plurality of pieces of image data, projects an image obtained by combining the images located in predetermined display regions of the respective terminal apparatuses;
• and
• an image display position change unit that changes the display position of the image to a display region other than the predetermined display region, on conditions that the display control unit terminates in the predetermined display region the display of the image generated based on the application program controlled by the application program control unit, and the image generation unit generates the image based on the application program again.

A computer-readable recording medium recording a program for allowing a computer to function as:

• image generation means for generating image data based on an application program;
• display control means for controlling display of an image based on the image data generated by the image generation means and controlling termination of the display;
• predetermined region image transmission means for, when a position of the image based on the image data generated by the image generation means is in the predetermined display region, partially or entirely transmitting the image data of the image to the image projection apparatus via the communication path, in order that an image projection apparatus acquiring a plurality of pieces of image data from a plurality of terminal apparatuses via a communication path, and projecting images based on the plurality of pieces of image data, projects an image obtained by combining the images located in predetermined display regions of the respective terminal apparatuses;
• and
• image display position change means for changing the display position of the image to a display region other than the predetermined display region, on conditions that the display control means terminates in the predetermined display region the display of the image generated based on the application program, and the image generation means generates the images based on the application program again.
