Abstract

An imaging apparatus, comprising a receiving unit which receives a radio signal from an IC tag attached to a subject, a read unit which reads IC tag information recorded on an IC tag from each received radio signal, an image pickup unit which captures the subject and a first storage unit which stores IC tag information read from the IC tag and an image captured by the image pickup unit after associating the information with the image.

Claims

1. An imaging apparatus, comprising:

a receiving unit which receives a radio signal from an IC tag attached to a subject;

a read unit which reads IC tag information recorded on an IC tag from each received radio signal;

an image pickup unit which captures the subject; and

a first storage unit which stores IC tag information read from the IC tag and an image captured by the image pickup unit after associating the information with the image.

2. The imaging apparatus according to claim 1, further comprising:

an intensity detection unit which detects intensity of each received radio signal, wherein

the first storage unit stores intensity information obtain by associating the IC tag information read from each IC tag with intensity of a radio signal from each IC tag.

3. The imaging apparatus according to claim 2, further comprising:

a second storage unit which stores intensity distance correspondence information prescribing correspondence between intensity of the radio signal from the IC tag and a distance to the IC tag.

4. The imaging apparatus according to claim 3, wherein

the first storage unit stores distance information obtained by associating IC tag information read from each IC tag with a distance corresponding to intensity of the radio signal from each IC tag according to the intensity distance correspondence information.

5. The imaging apparatus according to claim 3, further comprising:

a distance-measuring unit which measures a distance to a main subject on which the image pickup unit obtains focus; and

a designation unit which designates main IC tag information recorded on an IC tag of the main subject according to a distance to the main subject, the intensity distance correspondence information, and the intensity information.

6. The imaging apparatus according to claim 4, further comprising:

a distance-measuring unit which measures a distance to a main subject on which the image pickup unit obtains focus; and

a designation unit which designates main IC tag information recorded on an IC tag of the main subject according to a distance to the main subject, the intensity distance correspondence information, and the intensity information.

7. The imaging apparatus according to claim 5, wherein

the distance-measuring unit is a distance-measuring sensor.

8. The imaging apparatus according to claim 6, wherein

the distance-measuring unit is a distance-measuring sensor.

9. The imaging apparatus according to claim 5, wherein

the distance-measuring unit detects a focal evaluation value indicating sharpness of a subject image based on a high frequency component in a signal output by an image pickup element, and measures a distance to a main subject based on a focal length of a lens having the focal evaluation value as an extreme value.

10. The imaging apparatus according to claim 6, wherein

the distance-measuring unit detects a focal evaluation value indicating sharpness of a subject image based on a high frequency component in a signal output by an image pickup element, and measures a distance to a main subject based on a focal length of a lens having the focal evaluation value as an extreme value.

11. The imaging apparatus according to claim 5, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

12. The imaging apparatus according to claim 6, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

13. The imaging apparatus according to claim 7, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

14. The imaging apparatus according to claim 8, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

15. The imaging apparatus according to claim 9, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

16. The imaging apparatus according to claim 10, further comprising:

a position detection unit which detects a position of the main subject, wherein

the first storage unit stores the main IC tag information and the position of the main subject after associating the information with the position.

17. The imaging apparatus according to claim 1, wherein

the first storage unit is an image file recording an image captured by the image pickup unit.

18. The imaging apparatus according to claim 17, wherein

IC tag information read from the IC tag is stored in a header portion of the image file.
