Abstract

A composition determination device includes: a subject detection unit configured to detect a subject in an image based on acquired image data; an actual subject size detection unit configured to detect the actual size which can be viewed as being equivalent to actual measurements, for each subject detected by the subject detection unit; a subject distinguishing unit configured to distinguish relevant subjects from subjects detected by the subject detection unit, based on determination regarding whether or not the actual size detected by the actual subject size detection unit is an appropriate value corresponding to a relevant subject; and a composition determination unit configured to determine a composition with only relevant subjects, distinguished by the subject distinguishing unit, as objects.

Claims

composition determination means configured to determine a composition with only relevant subjects, distinguished by said subject distinguishing means, as objects.

2. The composition determination device according to claim 1, further comprising:

subject distance detection means configured to detect a subject distance for each subject detected by said subject detection means; and

subject size detection means configured to detect an in-image size which is the size of the subject in said image, for each subject detected by said subject detection means;

wherein said actual subject size detection means detect actual size for each subject detected by said subject detection means, by obtaining said actual size using at least said subject distance and said in-image size.

3. The composition determination device according to claim 2, wherein said subject distinguishing means are configured to perform determination regarding whether or not said actual size obtained using at least said subject distance and said in-image size is an appropriate value corresponding to a relevant subject after having been corrected using a zoom power value set in an imaging apparatus configured to acquire said image data by imaging.

4. The composition determination device according to either claim 2 or claim 3, wherein said subject detection means are configured to perform determination of a predetermined attribute relating to the difference in size of each detected subject, in actual measurements;

and wherein said subject distinguishing means are configured to perform determination regarding whether or not said actual size obtained using at least said subject distance and said in-image size is an appropriate value corresponding to a relevant subject after having been corrected using a coefficient corresponding to said determined attribute.

5. A composition determination method comprising:

first detecting, of a subject in an image based on acquired image data;

second detecting, of the actual size which can be viewed as being equivalent to actual measurements, for each subject detected in said first detecting;

distinguishing relevant subjects from subjects detected in said first detecting, based on determination regarding whether or not the actual size detected in said second detecting is an appropriate value corresponding to a relevant subject; and

determining a composition with only relevant subjects, distinguished in said first detecting, as objects.

6. A program causing a composition determination device to execute:

first detecting, of a subject in an image based on acquired image data;

second detecting, of the actual size which can be viewed as being equivalent to actual measurements, for each subject detected in said first detecting;

distinguishing relevant subjects from subjects detected in said first detecting, based on determination regarding whether or not the actual size detected in said second detecting is an appropriate value corresponding to a relevant subject; and

determining a composition with only relevant subjects, distinguished in said first detecting, as objects.

7. A composition determination device comprising:

subject detection means configured to detect a subject in an image based on acquired image data;

composition determination means configured to determine a composition with only relevant subjects, distinguished by said subject distinguishing means, as objects.

8. The composition determination device according to claim 7, wherein said subject distinguishing means are configured to perform determination regarding whether or not said in-image size is an appropriate value corresponding to a relevant subject after having been corrected using a zoom power value set in an imaging apparatus configured to acquire said image data by imaging.

9. The composition determination device according to either claim 7 or claim 8, wherein said subject detection means are configured to perform determination of a predetermined attribute relating to the difference in size of each detected subject, in actual measurements;

and wherein said subject distinguishing means are configured to perform determination regarding whether or not said in-image size is an appropriate value corresponding to a relevant subject after having been corrected using a coefficient corresponding to said determined attribute.

10. A composition determination method comprising:
