Abstract

There are provided a transparent display device configured to be capable of giving a predetermined field of view including a natural image of a projection board to the vision of an operator and to be held on the head portion of the operator, an antenna arranged in the vicinity of the projection board and configured to carry out radio communication to at least one RFID tag for display storing display data, respectively, that has at least one predetermined display image displayed in the field of view, and a control circuit configured to obtain image data via radio communication through the antenna and to have the predetermined display image displayed by the display device so as to be superimposed on the natural image of the projection board in the field of view on the basis of the obtained image data.

Claims

1. A display processor comprising:

a transparent display device configured to be capable of giving a predetermined field of view including a natural image of a predetermined virtual projection portion to a vision of an operator and to be held on a head portion of said operator;

an antenna device configured to carry out radio communication with at least one RFID tag for display, arranged on said virtual projection portion or in the vicinity of said virtual projection portion, each of said RFID tag storing image related information for displaying at least one predetermined display image in said predetermined field of view;

a first information acquisition portion configured to get said image related information via radio communication through said antenna device; and

a display signal creating portion configured to create a display signal for displaying said predetermined display image by means of said display device so as to be superimposed on a natural image of said virtual projection portion in said predetermined field of view on the basis of said image related information gotten by said first information acquisition portion.

2. The display processor according to claim 1, wherein:

said first information acquisition portion gets display position information corresponding to a display position of said display image in said predetermined field of view, said display position information stored in said RFID tag for display through said antenna device; and

said display signal creating portion creates said display signal for displaying said predetermined display image at said display position in said predetermined field of view on the basis of said image related information and said display position information gotten by said first information acquisition portion.

3. The display processor according to claim 2, wherein:

said display signal creating portion includes a display mode control portion configured to create said display signal so that a display position or a display size of said predetermined display image in said predetermined field of view changes according to a distance or a direction between said operator and said virtual projection portion.

4. The display processor according to claim 3, wherein:

a plurality of said RFID tags for display are arranged at predetermined positions on said virtual projection portion or in the vicinity of said virtual projection portion; and

said display mode control portion creates said display signal so that said display position or said display size of said predetermined display image in said predetermined field of view changes according to an information acquisition result by said first information acquisition portion with respect to said plurality of RFID tags for display.

5. The display processor according to claim 4, wherein:

said display mode control portion creates said display signal so that said display position or said display size of said predetermined display image in said predetermined field of view changes according to an arrangement position of said RFID tag for display for which information acquisition by said first information acquisition portion was successful among said plurality of RFID tags for display.

6. The display processor according to claim 4, wherein:

said display mode control portion creates said display signal so that said display position or said display size of said predetermined display image in said predetermined field of view changes according to receiving signal intensity when information was successfully gotten by said first information acquisition portion from said RFID tag for display.

7. The display processor according to claim 3, further comprising a second information acquisition portion configured to get operator identification information from at least one of a plurality of RFID tags for operator through said antenna device, each of said plurality of RFID tags for operator associated with a corresponding operator, wherein:

said display mode control portion creates said display signal so that said display mode of said predetermined display image in said predetermined field of view changes according to both said image related information and said display position information gotten by said first information acquisition portion and said operator identification information gotten by said second information acquisition portion.

8. The display processor according to claim 3, further comprising a third information acquisition portion configured to get position identification information from a RFID tag for position identification through said antenna device, said RFID tag for position identification associated with a construction or a fixed object, wherein:

said display mode control portion creates said display signal so that said display mode of said predetermined display image in said predetermined field of view changes according to both said image related information and said display position information gotten by said first information acquisition portion, and at least one of said operator identification information gotten by said second information acquisition portion and said position identification information gotten by said third information acquisition portion.

9. A display processing system comprising:

a transparent display device configured to be capable of giving a predetermined field of view including a natural image of a predetermined virtual projection portion to a vision of an operator and to be held on a head portion of said operator;

at least one RFID tag for display configured to store tag identification information respectively, arranged at said virtual projection portion or in the vicinity of said virtual projection portion;

a database configured to store both said tag identification information and image information for displaying at least one predetermined display image in said predetermined field of view in association with each other, said image information corresponding to the RFID tag for display storing said tag identification information;

an antenna device configured to carry out radio communication with said at least one RFID tag for display;

a tag identification information acquisition portion configured to get said tag identification information via radio communication through said antenna device; and

an image information acquisition portion configured to access said database on the basis of said tag identification information gotten by said tag identification information acquisition portion and get corresponding said image information, wherein;

said display device displays said predetermined display image so as to be superimposed on a natural image of said virtual projection portion in said predetermined field of view on the basis of said image information gotten by said image information acquisition portion.
