Abstract

A photographing system in which a camera and a flash device cooperate to perform flash photographing and a photographic information transmission system in which a second hand-held terminal such as a flash device is controlled based on a signal relating to photographing that is transmitted from a first hand-held terminal such as a camera to the second hand-held terminal. A unique identification code for identification of the first handheld terminal or the second hand-held terminal is provided in at least one of the first hand-held terminal and the second hand-held terminal. The second hand-held terminal has a collating program for collating a unique identification code that is transmitted from the first hand-held terminal by using radio waves as a medium with a unique identification code provided in the second hand-held terminal.

3. The photographing system according to claim 1, wherein:

the flash device is provided with the unique identification code;

the camera has, in advance, the unique identification code of the flash device transmitted through the connection of the camera and the flash device, and in controlling the flash device the camera sends the unique identification code of the flash device to the flash device by using radio waves as a medium; and

the collating section collates the unique identification code of the flash device that is transmitted from the camera by using radio waves as a medium, with the unique identification code of the flash device provided in the flash device.

4. The photographing system according to claim 3, wherein

the camera stores unique identification codes a plurality of flash devices which are transmitted from the plurality of flash devices.

5. The photographing system according to claim 1, wherein

the number of the flash devices is plural, and each of the plurality of flash devices independently stores the unique identification code of the camera.

6. A photographic information transmission system in which a signal relating to photographing is transmitted from a first hand-held terminal to a second hand-held terminal by radio transmission to control a second hand-held terminal, wherein:

at least one of the first hand-held terminal and the second hand-held terminal is provided with a unique identification code for identification of the first hand-held terminal or the second hand-held terminal; and

the second hand-held terminal comprises a collating section for collating a unique identification code that is transmitted from the first hand-held terminal by using radio waves as a medium, with a unique identification code originally provided in the second hand-held terminal.

7. The photographic information transmission system according to claim 6, wherein

the first hand-held terminal and the second hand-held terminal are connected to each other in advance to transmit the unique identification code provided in at least one of the first hand-held terminal and the second hand-held terminal to the other of the first hand-held terminal and the second hand-held terminal.

8. The photographic information transmission system according to claim 6, wherein:

the second hand-held terminal is provided with the unique identification code;

the first hand-held terminal has the unique identification code of the second handheld terminal transmitted in advance through the connection of the first hand-held terminal and the second hand-held terminal, and in controlling the second hand-held terminal the first hand-held terminal sends the unique identification code of the second hand-held terminal to the second hand-held terminal by using radio waves as a medium; and

the collating section collates the unique identification code of the second hand-held terminal that is transmitted from the first hand-held terminal by using radio waves as a medium, with the unique identification code of the second hand-held terminal provided in the second hand-held terminal.

9. The photographic information transmission system according to claim 7, wherein

the first hand-held terminal and the second hand-held terminal are connected to each other via either of a lead wire and contact points.
