Description

  The present invention relates to a convex mirror that allows a camera photographer to adjust the position and angle of a camera lens while visually observing the composition of the subject and another subject.

  Conventionally, when a photographer shoots himself / herself as a subject when shooting with a digital camera, film camera, video camera, etc., the lens is pointed at the person, scenery, etc. that he / she wants to fit in the frame together with the camera lens position. And the angle was fixed with an approximate sense and the shutter or the recording button was pressed.

  In addition, there is a digital camera (for example, see Non-Patent Document 1) in which the angle of the liquid crystal monitor can be freely changed as seen in a mobile phone camera or a digital movie camera, and the shooting situation can be confirmed from the subject side. It was.

  Digital cameras with a rotating LCD monitor (Non-Patent Document 1) are rapidly becoming compact and almost disappeared. When shooting a photographer himself with a camera whose viewfinder and LCD monitor do not move, The photograph was taken with the lens facing the subject with an approximate sense, but the resulting photograph was often different from the composition that was assumed before photographing.

  An object of the present invention is to make it easy to confirm the position of a photographer himself / herself in a frame with a digital camera and a digital video camera equipped with a film camera or a liquid crystal monitor having no rotation function.

  In order to achieve the above object, the present invention provides a mirror surface material such as a glass mirror on which a photographer can photograph a subject including himself, a mirror surface metal, or a plastic plated resin surface. Is provided on the lens mounting surface, and it is possible to confirm the shooting composition by observing the background reflected on the mirror plate and your position.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In situations where the photographer has a camera, puts his finger on the shutter and focuses the lens on his own, the length of the photographer's arm is the maximum focus distance of the subject, which is very close. When the imaging situation equivalent to that of visual observation is required for the mirror plate described in “0007”, a convex reflecting mirror that can be reflected in a wide area (hereinafter referred to as convex mirror 1) is used.

  In order to utilize the convex mirror described in “0009” in a camera having a function of a general focal length of a 35 mm lens to a wide-angle shooting 24 mm lens, the area of the convex mirror 1 is the camera as shown in the use example of FIG. In a range that can be accommodated on the 8-lens mounting surface, the composition of the subject can be visually confirmed by setting the R value of the convex mirror within the range of 20 mm to 200 mm.

  In addition, the present invention is sufficiently effective even when the surface of the convex mirror is not crafted. However, by applying a mark 2 such as a hole in the center of the convex mirror, the two-shot image is taken as shown in FIG. When this is done, the center position of the subject reflected on the mirror surface can be easily understood, and it is possible to adjust the height and angle of the camera lens more quickly and finely than when no mark is provided.

  As an example, when taking a picture with a compact digital camera having a lens with a focal length of 35 mm, the picture is taken with the size 11 of the 35 mm frame shown in FIG. 7, but the R value is 20 mm (22) as shown in FIG. When the circular convex mirror of FIG. 2 having a diameter of 20 mm (20) is used, the subject is reflected in a wide angle as shown in FIG. 8 and the entire subject can be seen, but the subject 12 that is not actually reflected is reflected on the convex mirror. End up.

  As another example, when shooting with a compact digital camera having a wide-angle function of a lens with a focal length of 24 mm, the image is shot with the size 10 of the 24 mm frame shown in FIG. 7, but the R value is 200 mm (19 as shown in FIG. 2) When the circular convex mirror of FIG. 2 having an area diameter set to 20 mm (20) is used, only the subject himself 16 near the center appears large as shown in FIG. 8, and the mirror surface shown in FIG. The subject 13 that must be reflected does not fit in the circular convex mirror, and in the case of the circular convex mirror, the diameter needs to be considerably increased, which hinders the convenience of the compact digital camera.

  From the examples of “0012” and “0013”, it is preferable to determine the R value and the area of the convex mirror within the above range.

  As a method of marking the center of the convex mirror, of course, it is particularly effective to make a portion that does not reflect light by making a hole of several millimeters if it is a convex mirror material that can make the hole 2.

  Furthermore, the shape of the convex mirror is not limited to a circle, and various shapes such as a square 23 are conceivable.

  As a method of installing the convex mirror described in “Best Mode for Carrying Out the Invention”, it can be provided on the camera body itself as shown in FIGS.

  As a detachable type, when the convex mirror is held with the left hand as shown in FIG. 1, the protruding portion 4 can be pressed and fixed by a finger 7 other than the one pressed by the shutter 6.

  In the case of the detachable convex mirror of “0018”, as shown in FIG. 2, the strap string passing hole 3 is passed through a string or the like and tied to the neck strap or hand strap hole provided in the camera as an accessory. It can be used quickly when needed.

  As another installation method, it can be fixed to the camera body using a fixing member such as an adhesive tape on the back surface of the convex mirror.

  Regarding the detachable convex mirror of “0018”, the case where the double-sided tape is used for the back surface portion 5 shown in FIG. 3 and the protruding portion is pressed and fixed with a finger without removing the release paper is shown in FIG. In this way, both functions can be provided when peeling paper is peeled off and adhered and fixed.

  Further, as shown in FIG. 13, in the case of a detachable convex mirror, the convex mirror 23 is fitted and fixed to a pedestal made of a material such as plastic, rubber, silicon rubber or the like, and is the same as the protruding portion 4 described in “Example 2”. The finger holding portion 25 can be fixed to the camera using a finger.

  A strap string passage hole 3 is provided in the finger holding portion of the pedestal described in the above “0022” and can be tied to the camera body with a string or the like.

  As described above, the present invention makes it easy to take two-shots even when there is no third party requesting to press the shutter, and it is easy to take an accurate composition shot with various subjects including yourself even when traveling alone. Is obtained.
