Problems solved by technology

[0008] However, by operating the projector 20 itself or controlling the projector 20 according to an instruction from the notebook personal computer 30, the projector 20 can only be controlled by a person who is near these projectors 20 or the notebook personal computer 30.
In addition, although the projector can be controlled by a remote controller conventionally, since the projector and the remote controller cannot be connected to enable two-way communication, projection data, etc. Image being projected, etc.

Abstract

A projector and a mobile terminal are connected wirelessly in two-way communication, and thus the projector is controlled by the mobile terminal. Also, projection data is exchanged between the mobile terminal and the projector, or between a data server connected to a network and the projector using a command of the mobile terminal. Furthermore, when a plurality of mobile terminals send projection data simultaneously, a communication enabled state is established with only one mobile terminal by a predetermined procedure, or one projector's projection screen is divided in order to project a plurality of projection data simultaneously.

Description

technical field [0001] The present invention relates to control of a projector using a portable terminal that communicates through a wireless connection. Background technique [0002] Figure 15 It is a configuration diagram showing an example of a conventional projector system connected to a network. exist Figure 15 In the network 10, a projector 20, a notebook personal computer 30, a server 40, and desktop personal computers 51, 52, 53, and 54 are respectively connected. Furthermore, tablets 61 , 62 , 63 , and 64 are directly connected to the projector 20 . [0003] Control information and projection data from the notebook personal computer 30 are sent to the projector 20 via the network 10 , and the data are projected on the projection surface 70 . In addition, the notebook personal computer 30 also sends control information to the server 40 or the desktop personal computers 51, 52, 53, 54 via the network 10, and the projection data stored in the server 40 or the deskt...
