Embodiment Construction
[0018] Such as figure 1 Shown, a kind of liquid crystal anti-glare device of digital camera of the present invention is characterized in that, it comprises: lens 1-3, image sensor 1-4, optical view finder 1-6, display 1-5. 1-2 is for taking pictures kind. The image is reflected by the reflective lens 1-8 and arrives at the camera 1-7 for viewing and is converted into an electrical signal, and the electrical signal is transmitted to the display 1-5 to display the image in real time. The LCD visor is located at position 1-3 or 1-6.
[0019] Beneficial effect
[0020] The invention will improve the viewfinder function of the camera and ensure the quality of photographing.

The invention provides a camera liquid crystal obturator, which adopts a nontransparent material shading plate which is arranged between an optical viewfinder image screen and an ocular lens and can be synchronously opened and closed with a reflector. When the reflector takes photos, the shading plate can be synchronously closed, so that glare from a lens can be blocked and the photographic quality can be ensured. When a camera finds a view, the shading plate is opened to ensure that a viewfinding light path is smooth.
Description
technical field [0001] The invention relates to a camera liquid crystal sealing device. Background technique [0002] There are two types of cameras, digital single-lens reflex cameras and consumer digital cameras. At present, the structure of a digital single-lens reflex camera is composed of a lens, a total reflection mirror, an image sensor, and a viewfinder. When the shutter is pressed, the front mirror is closed, and the light beam of the image passes through the lens, and is completely reflected to the optical viewfinder when it meets the mirror; when the shutter is pressed, the mirror opens, and the light beam of the image passes through the lens, and all of it is directed to the image sensor. The disadvantage of this structure is that when the shutter is pressed to view the view, the light beams of the image are all blocked by the mirror, the image sensor cannot be sensitive, and the composition of the viewfinder cannot be transmitted to the camera's display, so tha...
