Embodiment 1

[0026] This embodiment provides a lens, figure 1 A structural diagram of a lens according to an exemplary embodiment of the present application. Such as figure 1 As shown, the lens of the present embodiment includes a lens assembly and a reflection component. Among them, the lens assembly includes a transparent airbag and a transparent fluid, and the transparent fluid is filled in the inside of the transparent airbag; the reflection assembly is placed in the edge of the transparent airbag, for changing the temperature of the transparent fluid, and changing the transparent fluid by changing the temperature of the transparent fluid The volume, thereby changing the radius of curvature of the transparent airbag to change the focal length of the lens assembly.

[0027] Through the above structure, the temperature of the transparent fluid in the transparent airbag is changed by the temperature change assembly, which causes the volume to change, which in turn makes the radius of curvatur...

Embodiment 2

[0034] This embodiment provides a method of controlling the lens zoom, based on the lens as described above, can include changing the temperature of the transparent fluid based on the temperature change in the lens in the zoom instruction, and changing the transparent fluid by changing the temperature of the transparent fluid Volume, thereby changing the radius of curvature of the transparent airbag to change the focal length of the lens assembly.

[0035] In one example, the temperature of the transparent fluid is changed according to the temperature change of the transparent fluid according to the zoom command controlling the lens, and the volume of the transparent fluid is changed by changing the temperature of the transparent fluid, thereby changing the radius of curvature of the transparent airbag to change the focal length of the lens assembly. Can include:

[0036] When the zoom command is reduced, the control temperature change assembly is heated to heat the transparent fl...

Embodiment 3

[0041] This embodiment provides a computing device, including a memory and a processor, a computer program stored in a memory, and when the computer program is executed by the processor, the step of performing the control method of the lens zoom as described above is implemented.

[0042] In one embodiment, the computing device can include one or more processors (CPUs), input / output interfaces, network interfaces, and memory, which can specifically be a controller.

[0043] Memory may include non-permanent memory, random access memory (RAM), and / or non-volatile memory (ROM) or flash memory (Flash Flash Ram) in a computer readable medium. Memory is an example of a computer readable medium.

Abstract

The invention provides a lens, a zoom lens, a terminal and a lens zooming control method. The lens comprises a lens assembly which comprises a transparent air bag and transparent fluid, and the transparent fluid is filled in the transparent air bag; the temperature changing assembly is arranged on the edge of the interior of the transparent air bag and used for changing the temperature of the transparent fluid and changing the volume of the transparent fluid by changing the temperature of the transparent fluid, so that the curvature radius of the transparent air bag is changed, and the focal length of the lens assembly is changed. The volume of the lens is adjusted by changing the temperature of the transparent fluid, so that the volume of the lens can be finely adjusted, and the focal length of the lens can be finely adjusted.

Description

Technical field [0001] The present invention relates to the field of optical lenses, in particular, to a lens, zoom lens, and terminal, and a control method of lens zoom. Background technique [0002] With the development of the times, people's requirements for image acquisition are increasing, in which the lens of the image acquisition device is especially critical to the effect of the finally collected image. The zoom lens changes the focal length of the lens by changing the refractive index or curvature of the lens, having a small size, fast response speed, simple operation, no wear, long life, low power consumption, etc., so there is a mobile phone, digital camera, network The camera, endoscope, etc. have a good application prospect in pursuit of light, thin, short, and small optical systems. [0003] However, the zoom lens in the related art is multi-mechanically realized zoom, especially for liquid lenses in the zoom lens, by providing pressure by an additional pump to chan...
