Description

  The present invention relates to an auxiliary optical filter used for photographing a mobile phone camera and a digital camera.

  In recent digital cameras, the number of effective pixels has been increasing and the definition has been advancing in competition among manufacturers, and many cameras have been developed that can take pictures clearly and clearly. Many of the latest mobile phones have built-in digital camera functions that allow you to shoot still images, etc., and auto focus function that automatically adjusts the focus when shooting, macro shooting (close-up), and zoom function. The higher functionality of the digital camera with built-in mobile phone has enabled us to achieve sufficient resolution and image quality for the purpose of clearly taking pictures as a single camera with the advancement of the effective pixel count. ing.

  However, apart from the trend of high resolution and high definition, there is a camera called a toy camera that can take pictures that are soft and warm. A toy camera is an inexpensive camera made of a material such as a lens and housing, such as plastic, which is less expensive than a general camera, and uses a film as a recording medium or a digital camera. Compared to a normal camera, the focus is less accurate, flare (white blurred light) is included in the shot image, the photo is unexpectedly colored, and the periphery of the photo is compared to the center of the photo Although it is said that the quality of the camera is low, such as being dark and depressed, the chance of unpredictable shooting results and the softness of the photos that come from the low focus accuracy are the hobbies of photography It has been accepted by people and has become a boom.

  Like photos that can be taken with a toy camera, for example, soft tones, colors, dark areas around the surroundings, or light that diffuses radially, such as mobile phone cameras or digital In order to reproduce with a camera, an optical interchangeable lens, for example, a telephoto lens, a wide-angle lens, a fisheye lens, a close-up lens, or the like is used together. In the interchangeable filter, a prism filter that causes light diffusion or a subject is expressed softly. There is a method that uses a combination of a soft focus filter and a color filter that adds color to the image, etc., and a type in which various interchangeable lenses and interchangeable filters are fixedly attached to the front of the camera lens in front of the camera by various methods. Is sold.

  However, with the improvement in performance of mobile phone cameras, it has become possible to take a picture while checking the effect of the filter on the mobile phone display, so that various combinations of filters can be immediately exchanged during shooting. Although a structure is required, in the above-mentioned Patent Documents 1 and 2, the interchangeable lenses and interchangeable filters for mobile phones and digital cameras used in the above are various interchangeable lenses and interchangeable filters on the front surface of the camera lens. This is a method of taking a picture after fixing it by the method. Considering the case of actual shooting, it is time-consuming to select various interchangeable lenses and filters to be used, take them out, and attach them to the front of the camera lens before shooting. The problem of reducing the chances that the replacement filters will actually be used for shooting Which comprise.

  In addition, the use of various interchangeable lenses and interchangeable filters, such as wide lenses, diffusion filters, polarizing filters, prism filters, etc., is sold separately. As a result, the general user who has not been familiar with the camera has had the opportunity to use an interchangeable lens and a filter when photographing.

  In addition to the above-mentioned patent documents, there is currently ToyCamera, etc. that reproduces how to capture a toy camera in software for mobile phones iPhone (registered trademark) manufactured by Apple Inc. in the United States, but it is still in other mobile phones Such functions are not available.

  Therefore, in the present invention, in order to solve the above-described problem, the various filters shown in FIG. 4 are used as a strip-like spelling B, for example, a room where each filter rotates with a Hatmelivet D or the like. The filter spell B is connected to the camera phone and digital camera with the strap E, so that the filter spell B can be taken out and used at the time of shooting. In order to eliminate the hassle of shooting after fixing it to the front part, the strip-like spelling is rotated into a fan shape and deployed to select various filters, while the photographer himself supports the filter spelling on the front of the camera lens By taking pictures, you can use the filters instantly and check the monitor of the mobile phone or digital camera during shooting without taking time to install. Filter replacement of was to allow in a simple manner.

  According to the present invention, various filter groups are combined into one strip-like filter spelling, so that it can always be used as a strap for a camera-equipped mobile phone, etc. Shoot while checking the effect of the medium filter on the monitor. Also, since the filter can be replaced quickly, you can try various filter effects in a short time, so you can shoot with fun.

  In addition, since the filters are grouped into strips, it does not require a complicated production process due to its structure, so it can be produced at a relatively low cost and the replacement filter can be used easily. Various combinations of exchange filters can also be made, for example, by changing the combination of color filters, and the configuration can be adapted to the purpose of photographing.

  In addition, each filter group has a strip shape and is supported by the front of the camera lens for shooting, so that replacement filters can be used as needed for mobile phone cameras sold and used so far. Also, it can be widely used in new mobile phones to be commercialized.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a best mode for carrying out the present invention, in a state where an exchange filter spelling is supported in front of a photographing lens of a mobile phone. It is a figure which shows the structure of a filter spelling, (2-1) is a front view, (2-2) is the side view, (2-3) is explanatory drawing which expand | deployed each filter in fan shape. (3-1) and (3-2) are perspective views of a state in which the replacement filter spelling is supported in front of the photographing lens of the mobile phone. It is explanatory drawing of each filter which comprises filter spelling. It is explanatory drawing which showed the variation of the tunnel effect filter. It is Example 1 of the case for filter spelling, (6-1) is explanatory drawing which showed the time of use at the time of storage (6-2). It is Example 2 of the case for filter spelling, (7-1) is the explanatory view which showed the time of use, (7-1) is the time of accommodation. Examples of filter binding for digital camera are shown, (8-1) is a front view, (8-2) is a side view, and (8-3) is a digital camera filter front supporting the digital camera filter binding. (8-4) is the side view.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, A is a mobile phone body, and B represents filter spelling. At the time of shooting, the camera-equipped mobile phone A is supported with one hand as shown in FIG. 1, and a filter arbitrarily selected from the filter spelling B is held on the front part of the camera lens C with the other hand.

Since the filter binding B has a plurality of filters fastened by the Hatmelevet D in FIG. 2, the filters are selected by rotating and developing the filters in a fan shape around D as a central axis so that they can be used immediately.
At that time, by selecting a plurality of filters and putting them in a stacked state, it becomes possible to shoot with a combination of a plurality of filters. For example, another color can be created by combining a plurality of color filters from (b) to (b) in FIG. Or, for example, by combining the tunnel effect filter with the h and diffusion filters shown in FIG. 4, it is possible to take a picture with a soft tone excluding the digital stiffness. Furthermore, for example, by combining a prism filter and a color filter, it is possible to take a fantastic picture with color.
At this time, the re-tunnel effect filter is used to mean a filter that reproduces a drop in the amount of peripheral light that occurs in the camera lens.

In order to reproduce the feature of the toy camera, which is a feature that reduces the amount of light in the periphery, which is darker than the center part of the image, for example, a round hole is made in a thin black plate such as plastic, and the hole is made in front of the camera lens Shooting while keeping an appropriate distance in the area darkens the surrounding area, so that you can reproduce the effect of shooting with a toy camera.
At that time, as shown in FIG. 5, as a tunnel effect filter for this effect, not only the form of simply making a round hole in a black plate, re-round (round shape), but also the fine notches radially around the hole are jagged. A shape that is contained, a nu (star shape), a filter with a print that gradually increases in transparency toward the center, a circular shape, or a fiber around the hole A filter having a shape in which a filter is arranged, or a fiber (fiber type) may be used.

  In addition, the filter cover is prepared with the cover shown in Fig. 4, which is made of a material such as cardboard, and can be easily designed by individuals, such as cutting out and pasting photographs. It can be done. By changing this design arbitrarily, the spelling itself has its own personality and you can feel the enjoyment of having and using it. In addition, this cover may not be cardboard, but may be a material such as plastic, rubber, cloth or leather.

  As shown in FIGS. 6 and 7, a case may be attached to prevent stains and scratches on the filter spell. For example, in FIG. 6, the cylindrical case G is passed through the strap E in advance, and when the filter is used, the case G is slid along the strap E to expose the filter spell B (6-2). After that, the case F is stored again by sliding it to the original position (6-1). Or, for example, in FIG. 7, the filter spelling is wrapped together in a state where one side is opened (7-1), and when used, the case is rotated to expose the filter spelling (7-2). . The material of the case can be cloth, non-woven fabric or leather, and may be metal, rubber, plastic or the like.

As shown in FIG. 8, in order to cope with a general small digital camera, a filter spell having a size larger than that of a filter for a mobile phone may be made.
At that time, the filter spell B is supported and used on the front surface of the lens C of the digital camera A as shown in (8-3) and (8-4) in the same manner as the filter spell for mobile phones.
