Abstract

A display device includes: a determination unit that determines, on the basis of display information, a period of time during which a display unit displays the display information with a first display characteristic; and a controller that controls the display unit to display the display information with the first display characteristic and to display the display information with a second display characteristic when the period of time has elapsed since the display with the first display characteristic was started.

Claims

1. A display device comprising:

a display unit that displays input display information;

a determination unit that determines, on the basis of the display information, a period of time during which the display unit displays the display information with a first display characteristic; and

a controller that controls the display unit to display the display information with the first display characteristic and to display the display information with a second display characteristic when the period of time has elapsed since the display with the first display characteristic was started,

wherein the display information upon which the period of time is determined is at least one of (A) a number of characters in text of the display information, or (B) an amount of encoding of an image of the display information Wherein when the display information represented by display data is text, the controller counts the number of characters in the text represented by display data stored in a memory and then determines whether the number of characters counted is greater than a threshold; and

when the display information represented by the display data is an image, the controller encodes the display data stored in the memory and obtains its amount of encoding, and then the controller determines whether the amount of encoding obtained in is greater than a threshold.

2. The display device according to claim 1, wherein

the first display characteristic and the second display characteristic each include one or more characteristics that are a display brightness, a display color, a display contrast, and a display position.

3. The display device according to claim 1, wherein

the determination unit determines the period of time on the basis of an information amount or an information type of the display information.

4. The display device according to claim 1, wherein the display unit is a see-through type display.

5. The display device of claim 4, wherein the first display characteristic makes the display information more easily visually confirmed than the second display characteristic.

6. The display device of claim 4, wherein the second display characteristic is less likely to obstruct the field of view of a user using the display than the first display characteristic.

7. The display device according to claim 1, wherein the display unit is a see-through type, head-mounted display.

8. A method for controlling how input display information is displayed on a display device, the method comprising:

determining, on the basis of the display information, a timer limit value;

starting a timer;

determining whether or not a value of the timer exceeds the timer limit value;

responsive to a determination that the value of the timer does not exceed the timer limit value, displaying the display information with a first display characteristic, and otherwise, responsive to a determination that the value of the timer exceeds the timer limit value, displaying the display information with a second display characteristic which is different from the first display characteristic,

wherein the display information upon which the timer limit value is determined is at least one of (A) a number of characters in text of the display information, or (B) an amount of encoding of an image of the display information Wherein when the display information represented by display data is text, the controller counts the number of characters in the text represented by display data stored in a memory and then determines whether the number of characters counted is greater than a threshold; and

when the display information represented by the display data is an image the controller encodes the display data stored in the memory and obtains its amount of encoding, and then the controller determines whether the amount of encoding obtained in is greater than a threshold.

9. The method of claim 8, wherein the display device is a see-through type display.

10. The method of claim 9, wherein the first display characteristic makes the display information more easily visually confirmed than the second display characteristic.

11. The method of claim 9, wherein the second display characteristic is less likely to obstruct the field of view of a user using the display device than the first display characteristic.

12. The method of claim 8, wherein the display device is a see-through type, head-mounted display.

13. A non-transitory computer-readable recording medium storing a program for causing a computer of a display device to perform a process comprising:

determining, on the basis of display information, a timer limit value;

starting a timer;

determining whether or not a value of the timer exceeds the timer limit value;

responsive to a determination that the value of the timer does not exceed the timer limit value, displaying the display information with a first display characteristic, and otherwise, responsive to a determination that the value of the timer exceeds the timer limit value, displaying the display information with a second display characteristic which is different from the first display characteristic,

wherein the display information upon which the timer limit value is determined is at least one of (A) a number of characters in text of the display information, or (B) an amount of encoding of an image of the display information Wherein when the display information represented by display data is text, the controller counts the number of characters in the text represented by display data stored in a memory and then determines whether the number of characters counted is greater than a threshold; and

when the display information represented by the display data is an image the controller encodes the display data stored in the memory and obtains its amount of encoding, and then the controller determines whether the amount of encoding obtained in is greater than a threshold.

14. The non-transitory computer-readable recording medium of claim 13, wherein the display device is a see-through type display.

15. The non-transitory computer-readable recording medium of claim 14, wherein the first display characteristic makes the display information more easily visually confirmed than the second display characteristic.

16. The non-transitory computer-readable recording medium of claim 14, wherein the second display characteristic is less likely to obstruct the field of view of a user using the display device than the first display characteristic.

17. The non-transitory computer-readable recording medium of claim 13, wherein the display device is a see-through type, head-mounted display.
