Abstract

Disclosed herein is an image displaying method for a head-mounted type display unit which includes a frame of the glasses type for being mounted on the head of an observer, an image display apparatus attached to the frame, and a control section for controlling image display of the image display apparatus. The image display apparatus includes an image forming apparatus, and an optical apparatus. The image displaying method includes the steps of: storing a data group configured from a plurality of data in a storage section; adding a data identification code to each of the data; sending a designation identification code and display time information at predetermined intervals of time; and reading out the data whose data identification code coincides with the received designation identification code from the storage section and controlling the image forming apparatus to display an image based on the read out data.

Claims

1. A head-mounted type display unit comprising:

wherein;

the control section is configured to receive display time information from outside the head-mounted type display unit;

the control section is configured to control the image forming apparatus to display an image for a period of time corresponding to the display time information;

the control section comprises a storage section configured to store two or more data units, a first of the one or more data units comprising a first data identification code and first display data, a second of the one or more data units comprising a second data identification code and second display data; and

the first display data comprises text data or image data.

2. The head-mounted type display unit of claim 1, wherein the image display apparatus is a first image display apparatus, wherein the image is a first image, wherein the head-mounted type display unit further comprises a second image display apparatus, wherein the control section is further configured to control the second image display apparatus to display a second image, and wherein the control section is further configured to control an angle of convergence between the first and second images.

3. The head-mounted type display unit of claim 1, wherein the control section is further configured to receive a designation identification code from outside the head-mounted display unit, and to select, from the one or more data units, a data unit comprising a data identification code coinciding with the received designation identification code, and wherein the image displayed by the image forming apparatus corresponds to display data of the selected data unit.

4. The head-mounted type display unit of claim 3, wherein the control section is further configured to control a size of the image based, at least in part, on a distance between the head-mounted type display unit and an observation object.

5. The head-mounted type display unit of claim 4, further comprising a distance measuring apparatus configured to determine the distance between the head-mounted type display unit and the observation object.

6. The head-mounted type display unit of claim 3, wherein the control section is further configured to control a language of characters included in the image based, at least in part, on language data received from outside the head-mounted type display unit.

7. The head-mounted type display unit of claim 3, further comprising a language selection unit, wherein the control section is further configured to control a language of characters included in the image based, at least in part, on an operation of the language selection unit.

8. A head-mounted type display unit comprising:

(a) a frame,

(b) an image display apparatus attached to the frame, the image display apparatus including;

(A) an image forming apparatus, and (B) an optical apparatus configured to guide light outputted from the image forming apparatus,

(c) a control section configured to control the image display,

wherein the control section is configured to control a size of an image displayed by the image forming apparatus according to a distance between an observation object and the head-mounted type display unit;

wherein the control section comprises a storage section configured to store two or more data units, a first of the one or more data units comprising a first data identification code and first display data, a second of the one or more data units comprising a second data identification code and second display data; and

wherein the first display data comprises text data or image data.

9. The head-mounted type display unit of claim 8, wherein the image display apparatus is a first image display apparatus, wherein the image is a first image, wherein the head-mounted type display unit further comprises a second image display apparatus, wherein the control section is further configured to control the second image display apparatus to display a second image, and wherein the control section is further configured to control an angle of convergence between the first and second images.

10. The head-mounted type display unit of claim 8, wherein the control section is further configured to receive a designation identification code from outside the head-mounted display unit, and to select, from the one or more data units, a data unit comprising a data identification code coinciding with the received designation identification code, and wherein the image displayed by the image forming apparatus corresponds to display data of the selected data unit.

11. The head-mounted type display unit of claim 10, further comprising a distance measuring apparatus configured to determine the distance between the head-mounted type display unit and the observation object.

12. The head-mounted type display unit of claim 10, wherein the control section is further configured to control a language of characters included in the image based, at least in part, on language data received from outside the head-mounted type display unit.

13. The head-mounted type display unit of claim 10, further comprising a language selection unit, wherein the control section is further configured to control a language of characters included in the image based, at least in part, on an operation of the language selection unit.

14. A head-mounted type display unit comprising:
