Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a finder device, and more particularly to a finder device for visually recognizing a subject in a camera or the like.

[Prior Art] At the time of photographing, a photographer observes a subject by bringing one eye close to an eyepiece portion of a viewfinder of a camera and performs framing.
On the other hand, in recent years, with the progress of computerization of cameras, in general, a display element such as an LED (light emitting diode) is used to display information in a viewfinder so that a photographer can easily recognize shooting information such as exposure information. I have to.

[Problems to be solved by the invention] However, when the photographic information is displayed in the finder for observing the subject, particularly in recent years, a lot of information is displayed, and these displays hinder the finder field of view. It is inconvenient to carry out framing.
Therefore, in reality, the display is made small at the edge of the viewfinder field to the extent that it does not interfere with framing, but the more information there is, the smaller the characters and symbols that are displayed and the denser these display states become. However, there is a drawback that the shooting information is difficult to read.

On the other hand, conventionally, there is known what is called a Contool finder that is used by looking through with both eyes (see "Camera Industry Handbook", S54.7.15, published by Photo Industry Co., Ltd.). This is one in which one eye directly looks into the subject, and the other eye looks into the optical image frame that appears white and floats on a black background placed near the focal point of the ocular convex lens. Therefore, the subject and the optical image frame will overlap. However, this Contool finder is for always superimposing the optical image frame on the subject during framing, and does not display shooting information.

In view of the above points, the present invention is designed so that both eyes can be used.
An object of the present invention is to provide a finder device having two eyepieces, capable of surely visually confirming display of shooting information, and facilitating framing without a subject being obstructed by display of shooting information.

[Means and Actions for Solving the Problems] In the finder device of the present invention, one eyepiece is configured so that an object can be visually recognized through the eyepiece, and the other eyepiece is passed through the eyepiece. The display of information related to the object is configured to be visible, and the subject and the shooting information are recognized by both eyes of the photographer.

[Embodiment] The camera shown in FIGS. 1 and 2 is an embodiment of the camera to which the finder device of the present invention is applied, and the camera body 1 is provided with two eyepieces 2 and 3. . A subject image based on the subject light incident from the photographing lens 4 is projected on one eyepiece 2, and an LED, LCD (liquid crystal) or the like arranged in the camera body 1 is projected on the other eyepiece 3. Photographing information is projected by the display element. In the display of shooting information in FIG. 1,
The aperture value is F8, the shutter speed is 1/250, and the flash is in use, which is indicated by numbers, letters, and other symbols by lighting or blinking the LED. The background color of the displayed shooting information is gray, for example. Also,
The brightness of the shooting information in this display state can be adjusted appropriately.

Therefore, this camera is used by using binoculars as shown in FIG. That is, since the photographer 5 uses the right eye close to one eyepiece 2 and the left eye close to the other eyepiece 3, the photographer can visually recognize the subject with the right eye and the left eye with the left eye. You can see the shooting information. Therefore, in a state in which both eyes are open, as shown in FIG. 3, the subject image projected on one eyepiece 2 and the photographing information projected on the other eyepiece 3 are taken by the photographer. It can be recognized in the state where it overlaps in the head and the shooting information appears above the subject image.
Therefore, by adjusting the brightness of the displayed shooting information, you can emphasize the subject image or shooting information, so you can perform framing with both eyes open and recognize the shooting information. can do. As for the posture during shooting, it is much easier to keep both eyes open than to close one eye. However, even if the shooting information from the left eye is anxious during framing, only the subject image can be seen by closing the left eye, so that only framing can be focused. Also,
In this camera 1, as is apparent from FIG. 1, the structure 6 including the eyepiece 3 for displaying the photographing information and the display element in the camera body 1 for projecting to the eyepiece 3 is provided. The main body 1 is slidable in the direction of arrow a so that the distance between the two eyepieces 2 and 3 can be adjusted according to the distance between the eyes of the photographer.

Next, another embodiment of the camera to which the device of the present invention shown in FIG. 4 is applied will be described.

This camera is an electronic still camera, and the camera body 11
Each of the two eyepieces 12 and 13 provided on the display is an electronic viewfinder. Then, like the binoculars, since the hinge portion 11a is provided in the center of the camera body 11, the photographer holds the right half and the left half of the camera body 11 with both hands, and the solid line around the hinge portion 11a. The distance between the two eyepieces 12 and 13 can be adjusted by rotating in the directions of arrow b and arrow c from the position shown to the position shown by the chain double-dashed line. In this camera, subject light incident from a photographing lens (not shown) is imaged on an image pickup device in the camera body 11, and an electric signal of subject information from the image pickup device is supplied to the electronic viewfinders of the two eyepieces 12 and 13. It is designed to be guided by either one or both. Further, an electric signal of photographing information such as aperture value and shutter speed is also guided to either one of the two eyepieces 12 and 13. For example, when subject information is guided to the electronic viewfinder of one eyepiece 12 and shooting information is guided to the electronic viewfinder of the other eyepiece 13, two eyepieces 1
Since 2 and 13 are displayed as shown in Fig. 5 (A),
The subject image can be visually recognized by the right eye, and the shooting information can be visually recognized by the left eye. In this case, since the two eyepieces 12 and 13 are electronic viewfinders, it is possible to adjust the color, brightness, contrast, etc. of the subject image and the displayed photographic information, so that both eyes can be opened. It is possible to selectively emphasize and recognize one of the subject image and the shooting information which are overlapped in the head. Further, when such adjustment is troublesome, only the subject image or shooting information can be viewed by closing one eye as described above.

Further, since the dominant eye differs depending on the person, for example, for a person whose left eye is more likely to perform framing, by pressing an operation button (not shown), as shown in FIG. It is also possible to make the subject image displayed on 12, 13 and the photographing information reverse.

Further, in this camera, by pressing the operation button as required, the two eyepieces 12 and 13 can be made to display the subject image as shown in FIG. 5 (C). is there. In this case, it is also possible to form a stereoscopic image in the photographer's head by displaying the subject image in consideration of the parallax between the left and right eyes on the two eyepieces 12 and 13. It is possible.

In this way, the eyepieces 12 and 13 consisting of the electronic viewfinder
In the camera having the above, since there is a degree of freedom in processing the subject information and the shooting information, it is extremely easy to replace the display information in the two eyepieces 12 and 13 or to display only one information. is there.

Also in the case of the optical viewfinder, it is possible to interchange the subject image projected on the two eyepieces and the shooting information.
For example, as shown in FIG. 6, a mirror 25 is disposed in the incident optical path to one eyepiece lens 22, and the other eyepiece lens 22 is provided.
A mirror 26 and a relay lens 27 are arranged in the incident light path to the light beam 23. The mirror 25 is movable in and out of the optical path in the direction of the arrow d, and when the mirror 25 is retracted out of the optical path, the focus glass 28 of one eyepiece part is moved from the objective lens 25. The incident object image is projected, and the object image is captured by the eyepiece lens 22 in one eye of the photographer. At the same time, on the focus glass 29 of the other eyepiece, the display information on the display member 30 is projected through the lens 31, the mirror 26, and the relay lens 27, and this display information is displayed on the other eye of the photographer by the eyepiece lens 23. Be reflected. With the mirror 25 placed in the optical path as shown, the objective lens
The object image incident on 24 is reflected by mirror 25 and then mirror 2
6, guided through the relay lens 27 to the eyepiece lens 23,
Display information of the display member 30 is guided to a mirror 25 via a lens 31, reflected by the mirror 25, and guided to an eyepiece lens 22. By moving the mirror 24 in and out of the optical path in this way,
The object image and the display information respectively guided to the two eyepieces 22 and 23 can be reversed. Relay lens 27 above
Is for correcting a change in optical path length that occurs when the object image and display information are reversed. Further, in this embodiment, the structure 32 including the mirror 26, the relay lens 27, the focus glass 29, and the eyepiece lens 23 is adjustable in the direction of arrow e according to the distance between the eyes of the photographer. Has become. The change in the optical path length during the adjustment movement is also corrected by the relay lens 27.

In the embodiment shown in FIG. 6, when the mirror 25 is formed by a half mirror, the object image is guided to the two eyepieces 22 and 23 when the display member 30 is in the non-display state, and the display member 3
When 0 is in the display state, this display information is transferred to the two eyepieces 22,
Can lead to 23.

[Advantage of Device] As described above, according to the present invention, since the two eyepieces are provided so that both eyes can be used, the display of the photographing information can be surely visually recognized and the display is disturbed. The subject image can be reliably viewed without being blocked and framing is facilitated.
