Image Projection System, Terminal Apparatus, and Computer-Readable Recording Medium Recording Program
First Claim
1. An image projection system comprising:
- a plurality of terminal apparatuses; and
an image projection apparatus that acquires image data from each terminal apparatus via a communication path and projects an image based on the image data, whereinthe image projection apparatus includes;
an image acquisition unit that acquires a plurality of pieces of image data of images located in predetermined display regions of the respective terminal apparatuses via the communication path;
an image processing unit that combines the plurality of pieces of image data of the images located in the predetermined display regions of the respective terminal apparatuses; and
an image projection unit that projects an image based on composite image data generated by the image processing unit, andthe terminal apparatus includes;
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 a position of the image based on the image data generated by the image generation unit is in the predetermined display region, partially or entirely transmits the image data of the image to the image projection apparatus via the communication path; 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.

Abstract
In a case where display of an image is terminated in a predetermined display region and, then, the image is generated again based on an application program corresponding to the image of which the display is terminated, the image is generated in a region other than the predetermined display region without being projected in a visually recognizable manner. A terminal apparatus generates image data based on an application program, and terminates display of an image based on the image data. An image projection apparatus acquires a plurality of pieces of image data of images in predetermined display regions of a plurality of terminal apparatuses, combines the plurality of pieces of image data to generate composite image data, and projects an image based on the composite image data. The terminal apparatus may change a display position of the image to a display region other than the predetermined display region.
