Embodiment Construction

[0029] Below, while referring to the attached Figure 1 Embodiments of the present invention will be described.

[0030] figure 1 It is a diagram showing a schematic configuration of the image projection system 1 . The image projection system 1 includes a projector 100 and a terminal device 300 , and the projector 100 and the terminal device 300 are connected to each other via a network N such as the Internet so that data communication is possible.

[0031] The installation state of the projector 100 may be a floor-standing installation in which it is placed in front of the screen SC to be projected, or a suspension installation in which it is suspended from the ceiling. In the case where the projector 100 is installed on the floor, it may also be installed on a platform in which the projector 100 is placed on a platform installed on the floor. Furthermore, the object to which the projector 100 projects an image may be a flat projection surface such as the screen SC or a wa...

Abstract

An image projection system includes a projector and a terminal device. The projector includes a projecting section configured to project an image and a generating section configured to generate a correspondence image indicating correspondence between a projected image projected by the projecting section and a region where the projected image is movable. The terminal device includes a display section including a display screen, an operation section configured to receive operation on the display screen, and a control section configured to cause the display screen to display the correspondence image transmitted by the projector and transmit, during the display of the correspondence image, operation data indicating operation received by the operation section to the projector. The projector includes a control section configured to control the projecting section according to the operation indicated by the operation data and move a projecting position of the projected image.

Description

technical field [0001] The invention relates to an image projection system, a projector and a control method of the image projection system. Background technique [0002] Conventionally, there is known a technique for capturing a projected image projected by a projector and operating the state of the projected image (for example, refer to Patent Document 1). Patent Document 1 discloses a projection system including a projection device that projects an image including a mark onto a projection surface, and a terminal device that generates correction information for correcting the position of a mark based on a captured image captured on the projection surface and Send to projection device. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-192098 [0004] However, in the configuration of Patent Document 1, it is necessary to hold the terminal device in a state where the projection surface can be properly imaged. Therefore, it becomes complicated for the user to p...
