Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synchronizing device for a plurality of photographing means and a light source, and more particularly to a synchronizing device for synchronizing light emission of a flash light source with the plurality of photographing devices.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Patent Application Laid-Open No. Hei 7-301848, synchronously driving a camera by communicating with a control device of the camera is known.
This has been done conventionally.

[0003] This makes it possible to carry out synchronous photographing with a plurality of cameras as a plurality of photographing means.

[0004] For example, JIS B7102-19
As specified in 95, an X contact is standardized as a synchronous contact of a flash lamp as an external flash light source of a camera, and has been adopted as an interface usable in many still cameras and digital still cameras. I have.

[0005] A slave light-emitting device that emits an external light-emitting light source in synchronization with the light emission of a flash light-emitting light source built in or connected to a photographing device has been generally used.

[0006]

However, the prior art as described above cannot cope with the point that a plurality of photographing means are synchronized with a single flash light source.

[0007] This is a problem that occurs because the time of flash emission is so short that a minute time difference between photographing apparatuses due to individual differences in shutter units of a plurality of photographing means cannot be ignored. When flash light emission is performed based on a flash light emission instruction signal, a phenomenon occurs in which the shutter unit of another imaging device is not opened, and some flash devices do not contribute to exposure.

[0008] As described above, since there is a problem up to the individual difference between the shutter units, the related art which mainly focuses on photographing with the steady light cannot cope.

A digital camera uses a technology based on a video camera. Generally, in a model having a liquid crystal finder, an operation cycle (NTSC) based on a television standard such as NTSC or PAL is used.
In this case, camera control is performed on the basis of about 29 msec).

However, in this case, even if the shutter buttons of a plurality of digital cameras are pressed at the same time, an operation signal to the shutter unit is issued based on the above operation cycle. There is no synchronization between working cameras.

In such a situation, it becomes more difficult to synchronize the plurality of photographing devices with the flash light source.

The present invention has been made in view of this point, and it is an object of the present invention to provide a synchronizing device between a plurality of photographing means and a light source which can be synchronized with a flash light source in a plurality of photographing devices.

Further, in the prior art, it is necessary to connect a control device in the camera to mechanically connect and synchronize the shutters like a stereo camera in order to perform synchronization. With no camera, both cameras could not shoot simultaneously.

Further, control unique to each camera is required, and versatility is poor.

In view of this point, it is an object of the present invention to provide a synchronizing device of a plurality of photographing means and a light source which enables a plurality of cameras to be synchronized with a flash light source and which can easily perform simultaneous photographing.

In the prior art, both the X-contact branching device and the slave device synchronize a single or a plurality of flash light sources with a single photographing device. Single or multiple flash light sources were not compatible with synchronization.

It is another object of the present invention to provide a synchronizing device for a plurality of photographing means and a light source, which can be synchronized with a flash light source using a general-purpose function of a single photographing device. And

A light emission instruction signal is output from the input device 17.

The light emission instruction signal is transmitted to each digital camera 2
