Need to rotate relative to each other to easily adjust the different amount of light reduction, and the light reduction amount is firmly positioned at the required dimming value, thereby effectively improving the convenience, accuracy, stability and practicability in use.

According to the rapid development of digital technology, various digital products are not only improving in efficiency and performance, but also gradually popularizing with the decline in selling price. For example, the current digital camera has the advantage of instant imaging. The use of digital storage of images not only enables consumers to conveniently view and filter the captured images, but also facilitates subsequent image processing and sharing by consumers. Based on the above-mentioned advantages, digital cameras have been favored by consumers, and they are rapidly becoming popular in consumer digital products. In recent years, they have almost reached the popularity of human hands. At the same time, with the rapid development of the digital camera market. It also brings unlimited business opportunities to the market of peripheral photographic equipment.

Generally speaking, when consumers use a digital camera to capture a variety of different image effects, they often have a variety of different filter lenses, such as: soft focus mirror, star mirror, polarizer, light reducer Or various filters, etc. Please refer to Figure 1, the filter lens F can be It is assembled to the leading edge of a camera lens L, and can be mounted to a digital camera C with the camera lens L, so that when the user performs imaging using the digital camera C, an image with special effects can be obtained. Although, with the advancement of various image processing software, many of the aforementioned filter lenses have gradually been replaced by powerful digital technology, but polarizers and dimming mirrors are still very difficult to replace. As the name suggests, a dimming mirror is a filter that reduces the light transmission rate. Generally speaking, depending on the light passing rate, the dimming mirror can be divided into several different specifications. Consumers can add a single or multiple dimming mirrors of different specifications to the lens according to the actual needs of the shooting, so as to appropriately reduce the amount of light passing through the lens, so that it can be photographed in a strong light source environment, or Operate special shooting techniques (eg, use a black card to achieve uniform exposure in high contrast environments). The polarizer is a filter lens manufactured according to the principle of polarization of light, which has a grid-like crystal arranged in parallel. By rotating the polarizer and adjusting the angle of the grating crystal, the throughput of light of a specific polarization angle can be adjusted. When the consumer attaches a polarizer to the lens and appropriately adjusts the angle of the polarizer, it can effectively eliminate the reflection of the surface of the object (such as water surface, window glass or plant blade surface) and obtain the desired shooting effect.

Traditionally, since the specific size of the dimming mirror corresponds to a certain degree of light passing rate, consumers must separately purchase and carry different specifications of the dimming mirror so that it can respond to the light intensity of different shooting environments on the lens. Different sizes of dimming mirrors are installed separately. The foregoing method not only imposes a burden on the purchase cost on the consumer, but also is inconvenient in carrying. In addition, since the consumer has to repeatedly disassemble and replace the dimming mirror, the convenience of the consumer to operate the camera is greatly reduced. Although the traditional polarizer itself can achieve a certain degree of dimming effect, the polarizer is not a filter lens designed for the dimming function, so it cannot directly replace the dimming mirror. Moreover, in order to respond differently The light intensity of the shooting environment, consumers often use polarizers Need to shoot with different specifications of the reducer.

In order to improve the aforementioned shortcomings, the creator has developed a "multi-ring adjustable polarizing dimming mirror" and obtained the new patent right of Taiwan No. M436852 with its technical solution. The multi-ring adjustable polarized light reduction mirror is a "three-ring polarized light reduction mirror set", comprising a fixed ring, a first pivot ring and a second pivot ring, wherein the fixed ring One end can be fixed to the front edge of the camera lens; a first polarizing lens is fixed in the first pivoting ring, and one end of the first pivoting ring can be pivotally connected to the other end of the fixing ring; A second polarizing lens is fixed in the two pivoting rings, and one end of the second pivoting ring can be pivotally connected to the other end of the first pivoting ring. The first pivoting ring and the second polarizing ring are respectively rotatable relative to the camera lens independently of each other, so that the first polarizing lens and the second polarizing lens fixed therein can rotate relative to each other, The consumer can adjust the polarization angles of the first polarizing lens and the second polarizing lens by respectively rotating the first pivoting ring and the second pivoting ring respectively, and by changing the polarization between the polarizing lenses The angle of the angle is adjusted to adjust the passing rate of the incident light, so that the imaging effect of different light reduction amounts can be quickly and effectively adjusted by using a single mirror group. The product that applied this technical solution came into being, and it was immediately noticed by the majority of photographers, and quickly gained good repercussions in the market. Although the above-mentioned "three-ring polarized light reduction mirror group" has significantly improved convenience and practicability compared with the conventional filter lenses, the creators are not complacent and still look forward to it. It is possible to further design a polarizing and dimming mirror group that is more convenient and practical, in order to give back to the vast majority of photography.

For a long time, in addition to personally using the "three-ring polarized light reduction mirror group", the creators have actively shared various photographic experiences and experiences with related parties. In the foregoing process, it was found that although the aforementioned "three-ring type polarization reduction" The light microscope group not only allows consumers to freely adjust the passing rate of incident light, but also has the effect of polarizing the mirror to filter specific polarized light, but most consumers In the camera environment, it is not necessary to adjust the amount of dimming, but only to adjust the passing angle of the specific polarized light, in order to effectively eliminate the reflection of the surface of the object (such as water surface, window glass or plant blade surface), and obtain the ideal shooting. The effect, however, is that the first pivot ring and the second pivot ring are designed to be independent of each other independently of the camera when the amount of polarization is adjusted using the aforementioned "three-ring polarized light reduction mirror group". The lens rotates and the two are adjacent to each other, so that when the first pivot ring (or the second pivot ring) is rotated, the second pivot ring (or the first pivot ring) is easily mis-touched. Or the first pivoting ring and the second pivoting ring cannot be stably rotated in synchronization, so that the angle of the polarization angle between the polarizing lenses is always maintained at a fixed value, and the amount of light reduction cannot be maintained at an expected value. The fixed amount of light reduction, which impairs the quality of the image and its effect.

Accordingly, how to design an adjustable polarized light reduction mirror group not only can maintain the convenience of the polarized light reduction mirror group, but also allows the two polarized lenses to be stably stabilized according to the needs of the user. Rotate relative to the camera lens to adjust the polarization angle of the light at the minimum amount of light reduction, or independently and stably rotate relative to the camera lens to easily adjust the amount of dimming and securely position it in the desired The amount of light reduction, which effectively enhances the convenience, accuracy, stability and practicability of use, has become an important topic for this creation.

In view of the fact that the conventional filter lens or the aforementioned polarized light reduction mirror group has defects in the purchase cost, carrying and use, etc., the creator has acquired the knowledge acquired according to the industry for many years, and The rich experience accumulated by a professional photographer has been developed and improved, and finally developed a kind of adjustable multi-ring polarized light reduction mirror group with elastic radial positioning of the embedded card, which can be used in this creation. Improve the aforementioned various deficiencies so that they can Adjustable multi-ring polarized light reduction mirrors with convenience, accuracy, stability and practicality are provided for the majority of photography.
