Image display device
First Claim
1. An image display device comprising:
- a display part which is configured to allow a user to visually recognize a display image by projecting an image light corresponding to the display image on an eye of the user in a state where some ambient light reaches at least either one of eyes of the user;
a measuring instrument which is configured to measure brightness of the ambient light;
a determination unit which is configured to determine brightness of the display image;
a detection unit which is configured to detect the difference between the brightness of the ambient light and the brightness of the display image;
a decision unit which is configured to decide stop timing where the use of the display part by the user is temporarily stopped based on a detection result of the detection unit after the use of the display part is started by the user; and
a notification processing unit which is configured to perform stopping-of-use notification which prompts the user to stop the use of the display part at the stop timing decided by the decision unit.

Abstract
An image display device includes: a display part, a measuring instrument, a determination unit, a detection unit, a decision unit, and a notification processing unit. The display part allows a user to visually recognize a display image by projecting an image light corresponding to the display image on an eye of the user in a state where some ambient light reaches at least either one of eyes of the user. The measuring instrument measures brightness of the ambient light. The determination unit determines brightness of the display image. The detection unit detects the difference between the brightness of the ambient light and the brightness of the display image. The decision unit decides timing of temporarily stopping the use of the display part. The notification processing unit performs notification which prompts the user to stop the use of the display part at the timing.
