Abstract

The present invention provides a structure of a shading plate device, the shading plate device includes: a shading plate and a dimmer, the shading plate has a hole, and the dimmer is disposed on the On the hole, the user can place the shading plate device in front of a camera. By shaking the shading plate device, the camera can be exposed and balanced when facing a scene with high contrast between light and dark. Take pictures that balance the light ratio between the light and dark parts.

Description

Structure of shading plate device

The technology to which this creation belongs is to provide a structure of a shading plate device capable of balancing exposure and capturing light and dark parts to balance the light ratio.

With the rapid development of digital technology, various digital products have continuously improved in power and performance, especially the use of digital cameras has the advantage of real-time imaging. The use of digital storage to replace traditional negatives not only makes users It can more easily filter the captured images, and it is much more convenient than the traditional camera when the user performs subsequent image processing or sharing. Usually, in order to average the exposure of different parts of the screen, users will make black Paper jams cover their lenses, and use the time difference between the bright and dark exposures of the lens to segment exposure, so that users can shoot works with balanced exposure in bright and dark parts. However, holding the camera in one hand and shooting with black cardboard If you pay attention to it, the black cardboard may be damaged, and when the user is shooting outside, the paper equipment is often damaged due to the weather or external uncertain conditions, and its own materials that are easily damaged, etc., are actually Quite difficult and inconvenient.

Therefore, how to improve the above-mentioned missing problems is the technical difficulty of the creator of this case.

To this end, in order to achieve the above purpose, this creation provides a knot device installation The light-shielding plate device includes: a light-shielding plate and a dimmer, the light-shielding plate has a hole, and the dimmer is disposed on the hole and the adjustment The optical device is provided with a plurality of blades. The plurality of blades can overlap each other to form a round hole, and the plurality of blades are controlled by a lever to open and close the size of the round hole. The user can first set the The shading plate device is placed in front of a camera, the lever is used to adjust the appropriate position of the round hole, and then the shading plate device is shaken so that the camera can be exposed when facing a scene with high contrast between light and dark Balanced and photographed works that can balance the light ratio in both light and dark parts.

Please refer to FIGS. 1 to 5 for a three-dimensional appearance drawing, a three-dimensional exploded view, and schematic diagrams 1-3 of the preferred embodiment. It can be clearly seen from the figure that the shade device 1 includes There are: a shading plate 2 with a hole 21 on the shading plate; a dimmer 3 with a plurality of blades 31 on the dimmer 3, the plurality of blades 31 can overlap each other to form a circle Hole 311, and the plural blades 31 are controlled by a lever 32 to open and close the size of the circular hole 311; Wherein, the shading plate 2 is an opaque material; wherein, the dimmer 3 is disposed on the hole 21; the main reason is that the shading plate 2 has the hole 21, and The shading plate 2 is an opaque material, and the dimmer 3 is disposed on the hole 21 of the shading plate 2, and the dimmer 3 is provided with the plural numbers Blade 31, the plurality of blades 31 can overlap each other to form the circular hole 311, and the plurality of blades 31 is controlled by the lever 32 to open and close the size of the circular hole 311, that is to say, by dialing The lever 32 can cause the plurality of blades 31 to open and close to control the diameter of the circular hole 311. First, the user first places the shutter device 1 in front of a camera 4. The shading plate 2 is an opaque material, and light cannot penetrate the shading plate 2. When the shading plate device 1 is placed in front of the camera 4, the shading plate 2 will block Part of the external light is injected into the camera 4, and then the lever 32 is used to adjust the diameter of the circular hole 311 to obtain the proper position of the circular hole 311 into the light and the supplementary light area. The circular hole 311 is formed by overlapping and combining the plurality of blades 31. Therefore, the circular hole 311 can obtain a near-circular aperture, so that the position of the darker part in the camera 4 is exposed. At this time, The user may shake the light shielding device 1 slightly, and after the camera 4 sees the darker portion to obtain a close and sufficient light exposure, then quickly pull the light shielding device 1 away to let the camera The position of the brighter part in 4 starts to be exposed. After the exposure of the camera 4 is stopped, an exposure balance image can be obtained to complete the function and purpose of the shutter device 1 to balance the exposure of the camera 4.

The above-listed embodiments are used to clarify a preferred and feasible embodiment of this creation, not to limit the scope of this creation. Anyone who is familiar with this skill can do a little without departing from the spirit and scope of this creation. Changes and retouching, so the scope of protection of this creation shall be subject to the scope defined in the attached patent application.
