Description

上記目的を達成するために、本発明の画像表示システムによれば、スクリーンに画像を投影する投影装置と、前記スクリーンに投影された画像に対して行われる操作を受け付ける情報処理装置とを含む画像表示システムであって、前記スクリーンへ操作者が接近したことを検知する検知手段と、前記検知手段による検知結果に基づいて、前記投影装置により投影する画像の高さを制御する制御手段とを備える。 To achieve the above object, according to an image display system of the present invention, an image including a projection device that projects an image on a screen and an information processing device that receives an operation performed on the image projected on the screen. A display system, comprising: a detection unit that detects that an operator has approached the screen; and a control unit that controls a height of an image projected by the projection device based on a detection result by the detection unit. .

Claims

An image display system including a projection device that projects an image on a screen, and an information processing device that receives an operation performed on the image projected on the screen ,
Detecting means for detecting that an operator has approached the screen;
An image display system comprising: a control unit that controls a height of an image projected by the projection device based on a detection result by the detection unit .

When the control means detects that the operator is approaching, the control means causes the projection device to project an image at a height for operation by the operator according to the state of the operator, 2. The image according to claim 1, wherein when the operator does not detect that the operator has approached, the projection device projects the image to a height for presentation higher than the height for operation. Image display system.

Wherein, when the operator is detected that closer to said sensing means, and lower than the height of the reference height of the image, the detection that the operator has approached by said detecting means If non is, the image display system according to claim 1 or 2, characterized in that higher than the height of the reference position of the image.

The control unit according to any one of claims 1 to 3, wherein when the height of an image projected by the projection device is changed based on a detection result by the detection unit , the size of the image is further changed . The image display system according to any one of claims .

The information processing means further comprises coordinate conversion means for converting coordinate information input by the operator using an input device into coordinate information in an image whose height and size have been changed by the control means. Item 5. The image display system according to any one of Items 1 to 4.

The control means specifies the height of the operator who has approached the screen based on the detection result by the detection means, and the height of the image projected by the projection device according to the specified height. 6. The image display system according to claim 4, wherein the size and size are controlled .

The control means specifies the number of operators approaching the screen based on the detection result by the detection means , and determines the height and size of the image projected by the projection device according to the specified number. control to the image display system according to claim 4 or 5, characterized in Rukoto.

8. The detection unit according to claim 1, wherein the detection unit detects that an operator has approached the screen based on information detected by a plurality of sensors arranged on the screen. The image display system described in 1.
