Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable camera device that has a half mirror for alignment on the front part of the camera, and particularly relates to a portable camera device that has a half mirror for alignment on the front of the camera. This invention relates to a camera device that displays a frame shape for specifying the face position of a person to be copied.

[Prior Art] As a device for conveniently taking a face photo for identification to be attached to a driver's license, ID card IfIN, passport, etc., there is an instant photo box installed on the street. When you take a photo of yourself inside this instant photo box, you position the framework by looking at a small mirror installed below the camera lens.

Furthermore, Japanese Utility Model Application No. 49-9229 proposes a photographic device in which a half mirror (magic mirror) for image alignment is attached to a camera. When a copying person takes a photograph of his or her own face using this photographic device, he or she reflects his or her face on the half mirror in front of the camera and releases the shutter. With this, a desired photograph of one's face can be obtained.

[Problems to be Solved by the Invention] When taking a photo of one's face using the instant photo box described above, the position of the face is determined using a mirror located outside the camera lens, so it is necessary to shift the line of sight to the camera lens when taking the photo. Yes, the copied person feels uneasy about the position shift. Furthermore, since the device is large and heavy, it occupies a large installation space and is difficult to move and transport, making it difficult to use.

The photographic equipment of Utility Model No. 48-9229 has the camera attached to the rear of the half mirror in an open state, so outside light or reflected light from the back of the half mirror enters the camera lens, significantly reducing the saturation of the photograph. do. Also, the person being copied needs to be positioned while looking at their own face reflected in the half mirror.

It is difficult to judge how large the face reflected in the half mirror should be in order to obtain a photograph with a good framework, relative to the size of the half mirror. More precisely, when photographing faces for various types of certificates, if the subject of the photograph is not facing the camera lens accurately, the line of sight will shift from the center and the photographic face will look strange. therefore,
Simply looking into a half-mirror does not necessarily direct the user's line of sight toward the camera lens, making it impossible to obtain a natural-looking photograph of the person's face.

SUMMARY OF THE INVENTION An object of the present invention is to provide a small and portable camera device that allows a person to easily take a photograph of a person's face with a good framework and accurate line of sight.

[Means for solving the problems] In order to achieve the above object, the camera device according to the present invention has the following features:
A camera device that photographs a subject through a half-mirror placed in front, a display section for photographing a person to be copied with an optimal framework is displayed on the surface of the half-mirror, and the face of the person to be copied is aligned with the display section. The feature is that a camera lens is placed behind the half mirror at the position of the eyes of the person to be copied when the image is projected.

[Function] When the person to be copied makes sure that his/her own face is reflected in the display section displayed on the front eight-view mirror, and then releases the shutter of the camera device, a desired framework photograph of the face can be obtained. Moreover, when the person being copied aligns their face with the display on the half mirror, the camera lens is placed at the eye level of the person being copied, so the person's line of sight is looking directly into the camera lens. Therefore, the photographed headshot has a natural line of sight facing straight ahead.

Since the inside of the cabinet is in a dark room condition, unnecessary light components are not incident on the camera lens, and the chroma of the photographed images is improved.
