Abstract

(57) [Summary] [Purpose] Providing a remote finder that allows you to remotely look into the viewfinder of the camera. [Structure] A connection unit 2 having an image pickup means 5 is included, and when this connection unit is connected to a camera by a connection means 6 provided therein, the optical axis of the image pickup means coincides with the optical axis of a finder F of the camera. Is being done. Then, the image from the finder imaged by the image pickup means is transmitted to the monitor unit 3 by the communication means and reproduced on the monitor 7.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a remote finder for a camera that allows the finder of the camera to be viewed remotely.

[0002]

[Prior Art]

 The camera is usually equipped with a viewfinder so that the user can select a photo opportunity while viewing the image provided by the viewfinder. However, depending on the object to be photographed, it may not be possible to allow people to approach the subject, and it may not be possible to use the viewfinder to photograph. In this case, it is difficult to take a picture with the desired photo opportunity.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention aims to provide a remote viewfinder capable of remotely looking into the viewfinder of a camera.

[0004]

[Means for Solving the Problems]

 Specifically, a remote finder for a camera according to the present invention includes a connection unit equipped with an image pickup means such as a solid-state image pickup device using a CCD image pickup element. When the camera is connected to a camera, the optical axis of the image pickup means is aligned with the optical axis of the viewfinder of the camera. Then, the image from the finder captured by the image capturing means is transmitted to the monitor unit by a communication means such as an electrical or optical communication cable or wireless, and is reproduced on the monitor unit. The monitor unit further includes control / processing means, which controls the image pickup means via the communication means, for example, focuses the image pickup means on the image from the viewfinder, and if necessary, further controls. A function of remotely controlling the shutter of the camera and the like can also be provided. In this case, the connection unit may be provided with a relay unit that relays the control signal from the monitor unit.

This remote finder is designed to remotely reproduce the image provided by the finder of the camera on the monitor in this way. It is possible to remotely look at the finder on the monitor and ask for a photo opportunity. You can Therefore, by using this remote viewfinder, it becomes possible to take an optimal photo opportunity even for an object to which a satisfactory photo opportunity could not be obtained because a person cannot approach.

【Example】

 An embodiment of this invention will be described below. As shown in FIG. 1, the remote finder 1 according to the present invention comprises a connection unit 2, a monitor unit 3, and a cable 4 connecting both units 2 and 3.

The connection unit 2 includes a CCD image pickup device (not shown), an optical system for forming an image on the CCD image pickup device, and an image pickup means 5 including a processing circuit for processing an output from the CCD image pickup device into a video signal. The connection means 6 is attached to the camera, and the connection means 6 can be connected to and fixed to the camera M. The optical axis of the image pickup means 5 is adapted to match the optical axis of the finder F of the camera M in such a connected / fixed state. The adjustment means may be provided in the connection means 6. The connection / fixing of the connecting means 6 to the camera M can be performed by using, for example, a fixing portion to a tripod provided in the camera M.

The monitor unit 3 is composed of a monitor 7 and a control / processing means 8. The control / processing means 8 controls the image pickup means 5, and the image from the finder F picked up by the image pickup means 5 is displayed. The signal is processed by the control / processing means 8 and reproduced on the monitor 7. The cable 4 is for mediating communication between the units 2 and 3 and for supplying power to the image pickup means 5, and includes a plurality of conductors required for each.

When taking a picture with the camera M using such a remote finder 1, it is necessary to remotely operate the shutter of the camera M. However, such an operating means is not always the present invention. Since it is not necessary to be an element of the "remote finder" in 1 above, and a known one can be used, the description thereof is omitted.

[0010]

[Effect of the device]

 As described above, the remote finder according to this invention allows the camera finder to be remotely viewed, and by using this, it is possible to create an optimal photo opportunity even for subjects that are inaccessible or disliked by people. You will be able to shoot.
