## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a Divisional of U.S. application Ser. No. 09/604,352, filed Jun. 27, 2000, issued as U.S. Pat. No. 6,961,540, which is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 11-181599, filed Jun. 28, 1999, the entire contents of which are incorporated herein by reference.


BACKGROUND OF THE INVENTION
The present invention relates to an information processing system and a camera system, and more particularly to an information processing system comprising a radio (or wireless) communication terminal and an information appliance communicable with the radio communication terminal, for example, within a predetermined distance, such as about one meter, and a camera system comprising a radio (or wireless) communication medium and a camera communicable with the radio communication medium within a predetermined distance wherein each information processing system and camera system authorizes an information appliance user and a camera user, or a subject, or both of them.
Conventionally, as methods taking photographer information in an image photographed by means of a camera, the method in which a password is inputted at the time of camera photographing (Jpn. Pat. Appln. KOKAI Publication No. 08-315106) and the method in which biological information, such as fingerprint information, is utilized other than a password (Jpn. Pat. Appln. KOKAI Publication No. 05-127246) have been proposed.
However, in the conventional methods described above, the operation in which a password is actually inputted is not convenient to do by the reasons that the size of a camera equipment body is small and a user interface for inputting a password, such as a keyboard, operation buttons, or a display device, is insufficient as characteristics of a camera as a device.
Although the problem regarding a user interface can be cleared in the method in which biological information is employed, a problem exists in which an analysis means for authorizing a camera user and various kinds of data therefor have to be taken into a camera, thereby resulting in great difficulty in the realization in terms of mounting.

FIG. 10 shows an example in which at the time of photographing employing a camera 403 with a user authorization function by a radio communication and a subject information acquisition function, the doctor as a camera photographer 408 has the photographer authorized by holing a non-contact IC card/tag 401 which he owns to a camera 403. Then, he switches to a subject information acquisition mode by means of a subject information acquisition mode set button 403a or the like attached to the camera 403. A non-contact IC card/tag 402, such as a patient's registration card in which information peculiar to the patient as the subject 409 is recorded, that the patient as a subject 409 owns, is held to the camera 403 so that an image 406a photographed by the camera 403 in connection with distinguishment information 406b of the camera photographer 408 along with the subject 409 is recorded as an image file 406.
A doctor or a medical consulting engineer or the like is supposed as the photographer 408, who carries the non-contact IC card 401 for authorization of himself.
In this example, this non-contact IC card 401 works also as an access card to an in-hospital information system not shown in the drawing, and a doctor can access the data base of the in-hospital information system and the like, using this card.
The patient as the subject 409 can have a non-contact IC card/tag 402 peculiar to each patient.
This non-contact IC card/tag 402 may serve as a patient's registration card issued at each hospital.
The doctor as the photographer 408 holds the IC card 401 to the camera 403 in order to authorize himself first when photographing the patient as the subject 409.
Then, the doctor as the photographer 408 switches to the subject information acquisition mode by means of the subject information acquisition mode set button 403a or the like attached to the camera 403 and has the patient hold the IC card 402 of the patient 409 as the subject to the camera 403.
In the image file 406 photographed, the information 406b containing doctor's information and patient's information as shown in the drawing is added to the image 406a photographed.
In this case, as methods for adding information, information may be recorded on a header of a file, such as JPEG, or TIFF, or may be recorded in the image 406a as a digital watermark.
Further, as another method of adding information, information may be stored and managed in a different file from an image file related to the image file 406.
By these kinds of methods, managing the image file 406 becomes easy for the doctor as the photographer 408 later, and further an accident in which an image of the subject 409 as a patient is taken by mistake for a diagnosis can be prevented.
Moreover, the non-contact IC card 402 of the subject 409 as the patient, for example, can be employed for inputting the name of the patient in a clinical chart 407 without mistake by holding it to an information terminal 405 at the time of creating the clinical chart, or can be utilized for a delivery of a medicine or a confirmation of a patient at the time of operation.
In the explanation described above, although the patient as the subject 409, that is, a human, is exemplified, the subject is not necessary to be a human.
For example, as shown in FIG. 11, information of photographing part can be recorded at the time of photographing along with information of the photographer 410 by setting an IC tag 411 for each place to be checked as in the case of checking a body of an airplane 412 as a subject.
