Abstract

To provide an image display device configured to more faithfully display a projection image on a region where a physical quantity change has occurred. An image display device of the present invention includes a flow rate sensor and a screen on which an image from a projector is projected, and a control is performed such that the image is projected on the screen so as to include a position of the flow rate sensor that has detected the physical quantity change, and the image changes corresponding to a measured value change of the flow rate sensor. Preferably, a plurality of the physical quantity detection units are disposed, and the control is performed such that the image changes corresponding to the measured value changes in the respective physical quantity detection units.

First claim

The invention claimed is:

1. An image display device provided with a flow-rate sensor, the image display device comprising:
a flow-rate sensor that outputs a measured value in accordance with a strength of wind;
a display body on which an image from a projector is projected, the display body being disposed on a detection surface of the flow-rate sensor; and
a controller that performs an image display process based on the measured value output by the flow-rate sensor,
wherein the display body is provided with a through-hole that is communicated with the detection surface of the flow-rate sensor, and the flow-rate sensor detects a strength of wind that flows through the through-hole, and
wherein the controller performs a control such that the image is projected on the display body so that the image includes a position of the flow-rate sensor that has detected a change in the strength of wind, and the image changes corresponding to the measured value, output by the flow-rate sensor, of the change in the strength of wind.

2. The image display device provided with a flow-rate sensor according to claim 1 ,
wherein a plurality of the flow-rate sensors are provided,
wherein the display body is provided with a plurality of the through-holes that are communicated with the detection surface of the flow-rate sensor, and
wherein the controller projects the image onto the display body so that the image includes the positions of each flow-rate sensor that has detected a change in the strength of wind, and performs a control such that the image changes corresponding to the measured value of the change in the strength of wind at each flow-rate sensor.
