Abstract

An image display method displays image data obtained through a photographing operation performed at an image-capturing apparatus having a photographic optical system. The method includes: (i) image-capturing in which image data are generated by photographing a subject within a photographic image plane with the image-capturing apparatus; (ii) information collection in which subject information related to the subject is collected; (iii) correlating in which the subject information is made to correlate to a position within the photographic image plane; (iv) image display in which the image data are displayed at a display screen; (v) position specification in which a position on the display screen at which the image data are displayed is specified; and (vi) information display in which the subject information made to correlate to a position within the photographic image plane corresponding to the position specified in the position specification is displayed.

2. The image display method according to claim 1, wherein:

the information collection step is started up in response to an operation of an electronic instrument held by the subject to collect the subject information related to the subject from the electronic instrument.

3. The image display method according to claim 1, wherein:

the information collection step comprises;

a collection step in which the subject information related to the subject is collected from an electronic instrument held by the subject through communication with the electronic instrument; and

a display step in which the collected subject information is displayed.

4. The image display method according to claim 1, wherein:

in the information collection step, the subject information related to the subject is collected from an electronic instrument held by the subject through communication with the electronic instrument executed with a timing close to an operational timing of the image-capturing step.

5. The image display method according to claim 1, wherein:

the information collection step is manually started up with a timing bearing no relation to an operational timing of the image-capturing step to collect the subject information related to the subject from an electronic instrument held by the subject through communication with the electronic instrument.

6. The image display method according to claim 1, wherein:

in the correlating step, image-plane position information indicating a position of the subject within the photographic image plane is detected and the subject information is made to correlate with a position within the photographic image plane by using the image-plane position information.

7. The image display method according to claim 6, wherein:

the correlating step comprises;

a positional measurement step in which photographing position information is generated by detecting a position of the image-capturing apparatus;

an attitude detection step in which photographing attitude information is generated by detecting the attitude of the image-capturing apparatus;

a step in which subject position information indicating a position of the subject is collected from an electronic instrument held by the subject through communication with the electronic instrument;

a step in which the image-plane position information indicating the position of the subject within the photographic image plane is detected based upon photographic field angle information obtained in conformance to a focal length of the photographic optical system and an image-capturing size at the image-capturing apparatus, the subject position information, the photographing position information and the photographing attitude information; and
