Image marker attaching apparatus and method
A marker attaching apparatus attaches to an image a positioning marker for detecting a specific area in the image, and includes: an area size detection unit detecting a size of an area to which the positioning marker is attached; a marker adjustment unit adjusting the positioning marker depending on the detected size of the area; and a marker attaching unit attaching the adjusted positioning marker to the image.
1. A marker attaching apparatus for attaching to an image a positioning marker for detecting a specific area in the image, comprising:
an area size detection unit to detect a size of an area to which the positioning marker is attached;
a marker adjustment unit to adjust a size or a shape of the positioning marker depending on the detected size of the area and when the size of the of the detected area is smaller than a threshold, generating a new positioning marker by coupling two or more positioning markers to maintain a frequency characteristic of the coupled positioning markers; and
a marker attaching unit to attach the adjusted positioning marker to the image.
2. The marker attaching apparatus according to claim 1 , wherein
the marker adjustment unit switches a pattern of the positioning marker depending on the detected size of the area.
3. The marker attaching apparatus according to claim 1 , wherein
the marker adjustment unit adjusts a size of the positioning marker depending on the detected size of the area.
4. The marker attaching apparatus according to claim 1 , wherein
the marker adjustment unit adjusts a direction of the positioning marker depending on the detected size of the area.
5. The marker attaching apparatus according to claim 1 , wherein
the marker adjustment unit combines a plurality of positioning markers depending on the detected size of the area.
6. The marker attaching apparatus according to claim 1 , wherein
the marker adjustment unit adjusts the positioning marker while maintaining a frequency characteristic of the positioning marker.
7. A marker attaching method conducted by a marker attaching apparatus for attaching to an image a positioning marker for detecting a specific area in the image, comprising:
an area size detecting step to detect a size of an area to which the positioning marker is attached;
a marker adjusting step to adjust a size or a shape of the positioning marker depending on the detected size of the area and when the size of the of the detected area is smaller than a threshold, generating a new positioning marker by coupling two or more positioning markers to maintain a frequency characteristic of the coupled positioning markers; and
a marker attaching step to attach the adjusted positioning marker to the image printed on an analog medium.
8. The marker attaching method according to claim 7 , wherein
the marker adjusting step switches a pattern of the positioning marker depending on the detected size of the area.
9. The marker attaching method according to claim 7 , wherein
the marker adjusting step adjusts a size of the positioning marker depending on the detected size of the area.
10. The marker attaching method according to claim 7 , wherein
the marker adjusting step adjusts a direction of the positioning marker depending on the detected size of the area.
11. The marker attaching method according to claim 7 , wherein
the marker adjusting step combines a plurality of positioning markers depending on the detected size of the area.
12. The marker attaching method according to claim 7 , wherein
the marker adjusting step adjusts the positioning marker while maintaining a frequency characteristic of the positioning marker.
13. A computer-readable non-transitory tangible record medium storing a program used to direct a computer as a marker attaching apparatus to attach to an image a positioning marker for detecting a specific area in the image, comprising:
an area size detecting step to detect a size of an area to which the positioning marker is attached;
a marker adjusting step to adjust a size or a shape of the positioning marker depending on the detected size of the area and when the size of the of the detected area is smaller than a threshold, generating a new positioning marker by coupling two or more positioning markers to maintain a frequency characteristic of the coupled positioning markers; and
a marker attaching step to attach the adjusted positioning marker to the image.
14. The record medium according to claim 13 , wherein
the marker adjusting step switches a pattern of the positioning marker depending on the detected size of the area.
15. The record medium according to claim 13 , wherein
the marker adjusting step adjusts a size of the positioning marker depending on the detected size of the area.
16. The record medium according to claim 13 , wherein
the marker adjusting step adjusts a direction of the positioning marker depending on the detected size of the area.
17. The record medium according to claim 13 , wherein
the marker adjusting step combines a plurality of positioning markers depending on the detected size of the area.
18. The record medium according to claim 13 , wherein
the marker adjusting step adjusts the positioning marker while maintaining a frequency characteristic of the positioning marker.
