Three-ring polarizing and dimming mirror group with positioning ability

This creation is about a polarizing and dimming mirror group, especially a three-ring polarizing and dimming mirror group with positioning capability, which enables the two polarizing lenses to be provided with respect to the camera lens according to the needs of the user. Rotating to adjust the amount of polarization in a state of a fixed amount of dimming, or independently rotating relative to the camera lens to adjust the amount of dimming, thereby effectively improving the convenience 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. Referring to Figure 1, the filter lenses 60 can be It is assembled to the front edge of a camera lens 51, and can be mounted to a digital camera 50 with the camera lens 51, so that when the user performs imaging using the digital camera 50, 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with the advancement of various image processing software, many of the aforementioned filter lenses have gradually been replaced by powerful digital technology, but polarizers and dimming mirrors are still very difficult to replace.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 polarizing dimming mirror is a "three-ring polarizing dimmer group", comprising a fixing frame, a first pivoting frame and a second pivoting frame, wherein the fixing frame One end can be fixed to the front edge of the camera lens; a first polarizing lens is fixed in the first pivoting frame, and one end of the first pivoting frame can be pivotally connected to the other end of the fixing frame; A second polarizing lens is fixed in the two pivoting frames, and one end of the second pivoting frame is pivotally connected to the other end of the first pivoting frame. The first pivoting frame and the second pivoting frame 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 angle of each of the first polarizing lens and the second polarizing lens by respectively rotating each of the first pivoting frame and the second pivoting frame, 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 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 incident light Pass rate, and at the same time have the effect of polarizing the mirror to filter specific polarized light. However, in most imaging environments, consumers do not need to adjust the amount of light reduction, but only want to adjust the throughput of light with a specific polarization angle, in order to effectively eliminate The surface of the subject (such as the surface of the water, the window glass, or the surface of the plant's blade) is reflected to obtain the desired effect. However, when using the above-mentioned "three-ring polarized light reduction mirror group" to adjust the amount of polarization, The first pivoting frame and the second pivoting frame are respectively rotatable relative to the camera lens independently of each other, and are adjacent to each other, such that when the first pivoting frame (or the second pivoting frame) is rotated, It is easy to accidentally touch the second pivoting frame (or the first pivoting frame), or the first pivoting frame and the second pivoting frame can be stably rotated in synchronization, so that the polarization angle between the polarizing lenses The angle of the angle cannot always be maintained at a fixed value, so that the amount of light reduction cannot be maintained at an expected fixed amount of light reduction, which impairs the quality of the image and its effect.

According to this, how to design a three-ring polarized light and dimming mirror group with positioning ability can not only retain the convenience of the polarized light reduction mirror group, but also enable the two polarized lenses to be installed according to the user. The need to rotate relative to the camera lens to adjust the amount of polarization in a state of a fixed amount of light reduction, or to rotate independently of the camera lens to adjust the amount of light reduction, thereby effectively improving the practicality of use, that is, Creation is an important topic to explore here.

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 three-ring polarizing and dimming mirror group with positioning ability.
