Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording device integrated with a camera, and more particularly to an image recording and reproducing device that records information such as images and has a reproducing function.

[Conventional technology]

The electronic viewfinder equipped in the conventional camera-integrated image recording and reproducing apparatus of this type includes an Ibis and a small CRT display device of, for example, about 0.6 to 0.7 inches, built into the viewfinder. The user can view the video being shot or the reproduced image through the Ibis.

[Problem to be solved by the invention]

A viewfinder eye bead like the one above is usually
It can only be directed backwards, upwards, or horizontally to the main body of the recording/playback device. Therefore, if the user is in front of the main body, it is impossible to check the subject being imaged. be.

Furthermore, as mentioned above, this type of conventional viewfinder uses a display device with a small display area, and therefore it is difficult to view the image on the display device from a position quite far away from the main body of the device. .

Furthermore, even when playing back and confirming a captured video, the screen is small as described above, making it extremely difficult for the user to view the video even from a short distance.

Therefore, an object of the present invention is to provide an integrated camera equipped with a viewfinder having a relatively large display device suitable for directly monitoring images that have already been shot or images that are currently being shot on the screen without using an eyepiece. An object of the present invention is to provide an image recording and reproducing device.

Another object of the present invention is to provide a viewfinder that allows you to see a natural-sized and fine-grained image through the eyepiece even when using a display device with a relatively large screen as described above. An object of the present invention is to provide a camera-integrated image recording and reproducing device.

Still another object of the present invention is to provide a camera-integrated image recording and reproducing apparatus having a viewfinder that allows the subject being photographed to be confirmed even from in front of the viewfinder of the apparatus main body.

[Means for Solving the Problems and Their Effects] According to the present invention, a camera section includes an imaging lens system and an image signal conversion means for converting an optical image of a subject obtained through the lens system into a video signal; a recording means for recording the video signal from the image signal converting means on a recording medium; a viewfinder section including a display device and an eyepiece lens system; a camera-integrated image recording and reproducing device having a display control means for displaying an image on the display device based on the display device, wherein the display device is configured by providing a backlit liquid crystal display device with a relatively large screen, and the eyepiece A camera-integrated image recording and reproducing device is provided, characterized in that the magnification of the lens system is a reduction magnification.

According to this structure, the image being shot, etc. displayed on the screen of the liquid crystal display device, is displayed through the eyepiece lens system of the viewfinder in a natural size and with a fine grain so that the shape of each pixel is unnoticeable. It can be viewed as an image.

In the above case, the viewfinder section is integrally constructed with the main body of the recording/reproducing device, and when the display device is in a normal use position with respect to the housing of the main body, the display surface of the display device faces inside the main body and The display surface is connected so that it is substantially parallel to the housing surface of the main body, while being rotatable in a direction away from the housing surface using a part of the display device as a fulcrum, and the normal use position is located inside the device main body. A reflecting mirror may be provided to reflect an image on the display surface of the display device in the direction of the eyepiece lens system. In this case, the housing surface on which the display device is provided may be the upper surface of the main body, and the display device may be rotatable around an axis substantially perpendicular to the upper surface. With this configuration, the user can directly view the image being photographed or the image being reproduced as a large image on the display surface of the display device. Furthermore, the user can view such images from any position around the main body.

Further, the device is provided with a detection means for detecting that the display device is in the normal use position, and the display control means reverses the image on the display surface in a predetermined direction in accordance with the output of the detection means. By doing so, it is possible to compensate for the inversion of the image caused by the reflecting mirror.

Further, according to the present invention, the viewfinder section is divided into a first part to which the display device is attached and a second part to which the eyepiece lens system is attached, and the second part is divided into the first part to which the eyepiece lens system is attached. The first part may be attached to the main body of the apparatus by hinge-coupling so that the display surface of the display device is exposed when the second part is opened to the second part. This configuration is suitable for a relatively large camera-integrated image recording and reproducing device. Further, in this configuration, it is preferable that the first portion is attached to a surface portion of the device main body so as to be rotatable around an axis substantially perpendicular to the surface. Furthermore, if a reflecting mirror is provided inside the viewfinder section to reflect an image on the screen of the display device in the direction of the eyepiece lens system, the viewfinder can be made more compact.
