Abstract

To provide an image projecting system wherein the load on a communication path can be reduced and image data transmitted from different terminal apparatuses can be edited so that a plurality of persons can smoothly perform a group work and share information. The image projecting system (S) comprises a plurality of terminal apparatuses (2) and an image projecting apparatus (1). The image projecting apparatus (1) includes an image acquiring part that acquires the image data of an image (30) existing in a predetermined display area (45) of each of the terminal apparatuses (2); an image processing part that combines the acquired image data; an image projecting part that projects an image (50) based on the image data as combined; and an operation instruction processing part that, when acquiring an image operation instruction, transmits the image operation instruction to a terminal apparatus (2) that has transmitted image data to be operated. Each of the terminal apparatuses (2) includes a storing part that stores a data file; an image producing part that produces image data based on the data file; a predetermined area image transmitting part that, when an image (30) is existent in a predetermined display area (45), transmits the image data of a part or the entire of the image (30) to the image projecting apparatus (1); and an editing part that, when the image operation instruction is received from the image projecting apparatus (1), edits the data file in accordance with the image operation instruction.
