Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1 and 2, according to an embodiment of the first aspect of the present utility model, the optical structure includes a transparent screen 1 and a control module, and the control module is electrically connected to the transparent screen 1 to control the transparent screen 1, and the transparent screen 1 is black, i.e. opaque, in a default state.
The optical structure of the utility model is applied to an imaging device as an aperture structure, the imaging device comprises a lens 3 and a photosensitive module 2 with a photosensitive surface, the photosensitive module 2 comprises a convex lens 20 and a photosensitive element 21, a transparent screen 1 is arranged between the lens 3 and the convex lens 20, and a control module is used for adjusting the size of a transparent area 10 on the transparent screen 1 according to a control signal of equipment applied by the imaging device, such as a camera, so as to achieve the purpose of adjusting the aperture size.
What needs to be specifically stated is: the aperture structure is a device for controlling light to pass through the lens 3 and enter the light sensing surface of the device, and the aperture size can be expressed by an F value. In general, based on the principle of pinhole imaging, when the value behind F is smaller without changing the shutter, the larger the aperture, the more the amount of light is, the brighter the screen, the narrower the focal plane, and the greater the blurring of the main body background; when the value behind F is larger, the aperture is smaller, the light incoming amount is smaller, the screen is darker, the focal plane is wider, and the main body is clearer in front and rear. The larger the aperture is, the smaller the circle of confusion of the out-of-focus object is, the larger the definition is, and the larger the depth of field is; the smaller the aperture, the larger the circle of confusion of the out-of-focus object, the smaller the sharpness, and the smaller the depth of field.
Based on the above principle, the transparent screen 1 is arranged between the lens 3 and the convex lens 20, and the size of the transparent area 10 on the transparent screen 1 is adjusted by the control module to obtain the required aperture size, so as to obtain the required depth of field, and the transparent area 10 is shown in fig. 3.
The transparent screen 1 only has two working states of transparency and opacity, so that the adjustment of the transparent area 10 is more convenient and flexible, namely, the adjustment of the aperture size is convenient and flexible; compared with the prior art, the utility model has the advantages of simple structure, small occupied space, convenient maintenance and the like.
As shown in fig. 1, in some embodiments of the present utility model, a transparent screen 1 is disposed between a convex lens 20 and a photosensitive element 21; meanwhile, the transparent screen 1 has all opaque states, all transparent states and semitransparent states, and the semitransparent states comprise transparent areas and opaque areas arranged outside the transparent areas, so that the optical structure is more flexible to use.
The photosensitive element 21 may be an infrared complementary metal Oxide Semiconductor, and english is CMOS, which is an acronym for Complementary Metal-Oxide-Semiconductor.
As shown in fig. 1, 2 and 3, in some embodiments of the present utility model, the transparent area 10 is a circular area, which is disposed concentrically with the lens 3, and further, the transparent screen 1 is disposed coaxially with the lens 3. Of course, the transparent region 10 is not limited to the circular region listed above, but may be a rectangular region, an irregularly shaped region, or the like. After the structure is adopted, the transparent area 10 in the center of the transparent screen 1 represents an aperture, and at the moment, the larger the transparent area 10 is, the larger the aperture of the camera is, the smaller the transparent area 10 is, the smaller the aperture of the camera is, and the adjustment is more flexible and convenient.

The electronic device may be a camera or video camera mainly used for image capturing, or may be other electronic devices including an image capturing function such as a mobile phone or a computer.
When the aperture size is adjusted, the control unit transmits a corresponding control signal to the control module, and the control module controls the transparent screen to adjust the size of a transparent area concentric with the lens according to the received control signal, so that the purpose of adjusting the aperture size of the equipment is achieved; the aperture adjusting mechanism solves the technical problems of complex structure, high cost, difficult maintenance and the like of the aperture adjusting mechanism in the prior art.
