1. An image display device worn on a head of a user comprising:
a display configured to display information including at least one virtual object;
a visual line detector configured to detect a visual line of the user; and
a processor configured to:
display the information with a first definition on the display,
in response to determining that the user observes the virtual object included in the information for a prescribed period of time Ta or longer using a detection by the visual line detector, display the virtual object switching to a second definition that is higher than the first definition,
in response to determining that the user does not observe the virtual object displayed with the second definition for a prescribed period of time Tb or longer using a detection by the visual line detector, display the virtual object switching to the first definition from the second definition,
wherein the prescribed period of time Tb is longer than the prescribed period of time Ta, and
wherein the processor is configured to control an increase in the prescribed period of time Tb as a number of the virtual objects increases.
