Description

The present invention relates to a photographing method for a digital camera using a multi-angle mirror.

A general digital camera or the like has a viewfinder and a liquid crystal monitor on the back of the camera body, and the photographer sets the angle and the angle of view by aligning the direction of shooting with the camera and sets the angle and angle of view. In recent years, the degree of freedom for photography has further increased by making the liquid crystal monitor movable.

However, few small digital cameras have a movable LCD monitor. If the photographer is far from the viewing angle of the LCD monitor, such as when the photographer is shooting, I can't confirm. Even if the position of the camera is fixed before shooting, there is a problem that the shooting direction of the camera is only a rough guide, and when the actually shot image is viewed, the shooting target is shifted from the frame and fails. It was.

In the present invention, the apparatus is connected to a mirror that reflects an image reflected on a liquid crystal monitor, a fixing means that enables the mirror to be easily attached to a main body of a camera or the like, and a mirror and a fixing member if necessary. Support means.

ADVANTAGE OF THE INVENTION According to this invention, even if a photographer cannot confirm the imaging screen of a digital camera directly, it becomes possible to confirm an imaging screen indirectly, and the apparatus which enables imaging | photography without an angle shift | offset | difference is provided.

One embodiment of the present invention is shown in FIG. As shown in FIG. 1, the apparatus 1 includes a camera body (10), a fixed part (13) fixed for mounting a tripod on the bottom of the camera, a finder (11) reflecting a finder or a liquid crystal screen (M), and a mirror (11). The support portion (12) for changing the relative positional relationship between the fixed portion (13) and the mirror (11).

The fixing part (10) has a versatility and is convenient if it has a shape that can be fitted to an existing tripod fixing hole. Fixed to a flat surface of the camera using double-sided tape or Velcro (registered trademark) on a flat plate for simple versatility, the fixing part is firmly fixed to the camera It is also possible to choose any method if it is to be done. It is also possible to adapt a part of the camera by modifying it. When fixing to the tripod fixing hole, the position of the support portion (12) changes due to the screw hole, so that the position rotates by positioning between the screw portion of the fixing portion (13) and the root of the support portion (12). It is convenient to add an adapter that can. The adapter has a ring shape that can be rotated around a circular fixed part, and is provided with a screw hole that penetrates the ring from the outer periphery to the inner periphery. When the position is determined, the position is fixed by tightening the screw. Things can be used. Further, it is convenient to provide a hole for attaching the tripod to the lower part of the fixing part (13). Furthermore, the fixing portion (13) is not only fixed to the main body, but can also be applied to a tripod foot to which the main body is fixed.

The shape of the mirror (11) is not limited to a square small plane mirror, and the size, material, and shape (arbitrary, oval, etc.) are determined so that an image reflected on the liquid crystal screen can be confirmed from the required distance. In order to adjust the size of the image, a plane mirror, a concave mirror, and a convex mirror can be arbitrarily selected.

The support part (12) is convenient if it can fix the position so that the relative position of the mirror and the camera body can be changed so that the photographer can check the finder or the liquid crystal screen displayed on the mirror. good. Specifically, there is a flexible wire having both ends connected to a mirror and a fixed portion, or a bar whose angle and direction can be changed by a joint portion such as one or more hinges. It is more convenient if the bar is extendable.

FIG. 2 is a diagram showing a second embodiment of the present invention. FIG. 2A shows a camera body (20), a liquid crystal screen (M), a mirror (21), a support leg (22), a fixing portion (23), and a cushion (24). The apparatus shown in FIG. 2 (a) is an example in which the present invention is applied to a tripod having a small flexible leg that is generally commercially available. The device 2 has a fixing portion (23) for fixing the device to the tripod hole and four legs (22) having one end connected to the fixing portion (23), and the other end of the four legs is a mirror or rubber. It is connected to the cushion made by the above (however, the cushion may be omitted). Since it is uncertain which foot the mirror should be attached to when the device is fixed in the tripod hole, the tip of the leg (22) so that the cushion (24) and the mirror (21) are interchangeable. As shown in FIG. 2B, it is convenient to have a structure to which the cushion (24) and the mirror (21) are attached. In the figure, the hole provided in the cushion (24) is the same as the hole provided in the connecting portion attached to the back surface of the mirror (21), and is shaped and sized to fit one end of the leg. Then, when the device is fixed to the camera, the mirror is attached to the leg at an appropriate position, and the cushion is attached to the remaining leg. Finally, the leg to which the mirror is attached is fixed at a position where the liquid crystal screen (M) is appropriately reflected, and the position of the remaining leg is finely adjusted so that the camera is stabilized. In the above-mentioned embodiment, the cushion and the mirror are exchanged and used. However, a clip or the like for connection is attached to the mirror, and it is simply attached to the leg convenient for positioning the mirror by a fixing means such as a clip. It may be configured to be fixed only.

FIG. 3 is a diagram showing a third embodiment of the present invention. FIG. 3 shows a camera body (30), a liquid crystal screen (M), a support part (32), a mirror (31), and a fixed part (33). In the apparatus 3, the fixed part (33) is arranged so as to be close to the camera image screen (liquid crystal screen or the like), can be rotated in a direction perpendicular to the image screen on the opposite side of the screen of the fixed part (33), and The support part (32) which has a bending mechanism which can change the angle of the mirror attached there, and the mirror (31) connected to the support part are arrange | positioned. By changing the angle of the mirror and rotating the support portion, the screen can be confirmed from the top, bottom, left and right. In addition, when the direction in which the photographer confirms the captured image is constant, the support unit may simply have a bending mechanism and omit the rotation mechanism. A fixing part that uses a tripod hole, a thing that sandwiches the main body like a vise, or a thing that is pasted around the screen are convenient. As a good example of the fixing part (33) and the support part (32), a double ring structure can be mentioned. In this ring structure, the contact surfaces of the two rings are provided with concavities and convexities so that the two rings fit together, thereby preventing the two rings from being separated from each other and being rotatable with respect to each other. It is convenient to provide means (such as Velcro (registered trademark)) for fixing to the camera body on one side of this ring, and connecting means (hinge) with variable angle for connecting to the mirror on the other side.

The apparatus of these three embodiments is fixed to a camera, and a photographer confirms an image reflected and reflected on a mirror of an imaging screen such as a liquid crystal screen of a digital camera before photographing. Alternatively, the mirror is positioned by adjusting the angle. Next, while confirming the image reflected on the mirror, adjust the camera angle and shoot at an appropriate angle.

The gist of the present invention has been described based on the three embodiments as described above. However, those skilled in the art can make modifications and improvements within the scope of the claims based on the spirit of the present invention. You can easily understand what is possible. In the present invention, the liquid crystal of the digital camera has been described as an example. However, the multi-angle mirror of the present invention is not limited to the liquid crystal screen of the digital camera, but the camera finder, the liquid crystal screen of the video camera, and a normal personal computer. Those skilled in the art will readily understand that a screen having a viewing angle direction such as a liquid crystal screen for use is used to confirm an image from a direction different from the originally intended direction. It is also clear that such applications are included in the scope of the present invention.

It is a side view which shows the 1st Example of this invention. It is a side view which shows the 2nd Example of this invention. It is a side view which shows the 3rd Example of this invention.
