Abstract

According to an aspect, a mobile electronic device includes an image projecting unit and a processing unit. The image projecting unit projects an image to a projection area. The processing unit is configured to acquire information for a second image related to a first image placed in the projection area, and cause the image projecting unit to project the second image based on the information acquired.

Claims

an image projecting unit for projecting an image to a projection area; and

a processing unit configured to

acquire information for a second image related to a first image placed in the projection area, and

cause the image projecting unit to project the second image based on the information acquired.

2. The mobile electronic device according to claim 1, further comprising:

a sound detecting unit for detecting a sound, wherein

the processing unit is configured to

cause the image projecting unit to project the second image in synchronization with the sound detected by the sound detecting unit.

3. The mobile electronic device according to claim 2, wherein

the processing unit is configured to

acquire the information for the second image based on the sound detected by the sound detecting unit.

4. The mobile electronic device according to claim 2, wherein

the processing unit is configured to change the second image to be projected when detecting, based on the sound detected by the sound detecting unit, that the first image in the projection area is changed.

5. The mobile electronic device according to claim 1, further comprising:

an information acquiring unit for acquiring information from an external device, wherein

the processing unit is configured to

acquire the information for the second image through the information acquiring unit.

6. The mobile electronic device according to claim 5, wherein

the processing unit is configured to acquire the information including whether content of the first image is updated from the external device.

7. The mobile electronic device according to claim 1, further comprising:

an imaging unit for capturing an image in a direction in which the image projecting unit projects an image, wherein

the processing unit is configured to

determine the first image in the projection area based on an image captured by the imaging unit, and

cause the second image to be projected based on a result of the determining.

8. The mobile electronic device according to claim 5, further comprising:

an imaging unit for capturing an image in a direction in which the image projecting unit projects an image, wherein

the processing unit is configured to

determine the first image in the projection area based on an image captured by the imaging unit, and

acquire the information for the second image through the information acquiring unit based on a result of the determining.

9. The mobile electronic device according to claim 8, wherein

the processing unit is configured to

acquire identification information from the image captured by the imaging unit,

determine the first image in the projection area based on the acquired identification information, and

acquire the information for the second image related to the first image through the information acquiring unit.

10. The mobile electronic device according to claim 1, further comprising:

an imaging unit for capturing an image in a direction in which the image projecting unit projects an image, wherein

the processing unit is configured to change the second image to be projected when detecting, based on the image captured by the imaging unit, that the first image in the projection area is changed.

11. The mobile electronic device according to claim 7, wherein

the processing unit is configured to

acquire identification information from the image captured by the imaging unit, and

determine the first image in a projection area based on the acquired identification information.

20. The mobile electronic device according to claim 7, wherein

the processing unit is configured to,

based on the image captured by the imaging unit,

adjust a size of the second image to be projected, and

cause the second image to be projected to a predetermined position in the projection area.

21. The mobile electronic device according to claim 1, further comprising:

a connecting mechanism to be connected to a support.

22. An image projection system comprising:

the mobile electronic device according to claim 21;

the support for connecting to the connecting mechanism and fixing the mobile electronic device in a specific attitude; and

a screen fixed to the support and placed in the projection area.

23. The image projection system according to claim 22, wherein

the screen has a guide, indicating a placement position of a material on which the first image is printed, formed on the surface thereof.

12. A mobile electronic device comprising:

an image projecting unit for projecting an image to a projection area;

an imaging unit for capturing a first image placed in the projection area; and

a processing unit configured to

determine the first image in the projection area based on information captured by the imaging unit,

acquire information for a second image related to the first image based on a result of the determining,

perform an authentication process using at least one of the information for the second image and the first image, and

cause the image projecting unit to project the second image when it is determined that projection is permitted in the authentication process.

13. The mobile electronic device according to claim 12, wherein

the processing unit is configured to,

as the authentication process,

detect information to be authenticated included in the first image, and

cause the second image to be projected when the information to be authenticated included in the first image matches information to be authenticated included in the information for the second image.

14. The mobile electronic device according to claim 12, further comprising:

a communication unit for communicating information with an external device, wherein

the processing unit is configured to

as the authentication process,

detect information to be authenticated included in the first image,

transmit the information to be authenticated to the external device through the communication unit, and

determine, when receiving projection permission from the external device, that the projection is permitted.

15. The mobile electronic device according to claim 13, wherein

the information to be authenticated is identification code printed on a printed material placed in the projection area.

16. The mobile electronic device according to claim 13, wherein

the information to be authenticated is a signature entered in a face of the projection area.

17. The mobile electronic device according to claim 12, wherein,

upon detecting that the first image in a projection area is changed based on the image captured by the imaging unit,

the processing unit is configured to

acquire the information for the second image related to the changed first image, and

perform the authentication process again.

18. The mobile electronic device according to claim 12, wherein

the processing unit is configured to

acquire identification information from the image captured by the imaging unit,

determine the first image in the projection area based on the acquired identification information, and

specify the second image related to the first image.
