Problems solved by technology

[0003] Due to the user's demand for selfie and external shooting, most current mobile terminal devices such as smartphones are equipped with front cameras and rear cameras at the same time. However, in order to meet the needs of zooming, existing solutions mainly use external zoom modules To change the focal length of the camera, there are problems of unreliable structure and large lens size

[0049] figure 1 is a structural schematic diagram of the lens structure shown according to the first embodiment. Please refer to figure 1 The lens structure of this embodiment includes a lens barrel 21, a driver 22 and a flexible transparent sheet 23, the flexible transparent sheet 23 is arranged in the optical path in the lens barrel 21, and the driver 22 is used to drive the flexible transparent sheet 23 to deform to Change the focal length. Since the focal length can be changed only by driving the flexible light-transmitting sheet 23 built in the lens barrel 21 to deform, the structure is simple and the size of the lens can be reduced. In addition, the built-in structure is more stable and reliable.

[0050]The lens barrel 21 is a multi-step cylindrical structure, the small aperture end is the light entrance 211, the large aperture end is the light exit 212, the light entrance 211 is provided with a first lens 251, and there is a gap between the first lens 251 and the lig...

[0058] Figure 4 is a partial structural schematic diagram of the lens structure shown according to the second embodiment. Please refer to Figure 4 , Figure 4 Only the matching structure between the first bracket 313, the second bracket 315, the driving member 32 and the flexible light-transmitting sheet 33 is shown. The main differences between the lens structure of this embodiment and the first embodiment are:

[0059] The first bracket 313 is far away from the light entrance of the lens barrel relative to the second bracket 315 (refer to figure 1 The light entrance 211) in the lens barrel is set, the driver 32 is fixed on the side of the first bracket 313 facing the light entrance of the lens barrel, and the second support 315 abuts against a side of the flexible light-transmitting sheet 33 facing the light entrance of the lens barrel On the other hand, the contact point between the second bracket 315 and the flexible transparent sheet 33 is closer to the center of the...

[0064] Image 6 is a schematic structural diagram of the camera according to the third embodiment. Please refer to Image 6 The camera head of this embodiment includes the lens structure described in the first embodiment. When the lens structure described in the first embodiment is applied, the camera head of this embodiment can realize the adjustment between the standard focal length and the short focal length.

[0065] The camera also includes a photosensitive element 46 and a circuit board 47. The photosensitive element 46 is arranged on the light outlet of the lens barrel 41, and the light entering from the light inlet 411 of the lens barrel 41 enters the photosensitive element through the adjustment of each lens and the flexible light-transmitting sheet 43. 46 generates photosensitive signals, which are processed by chips on the circuit board 47 to generate images.

[0066] When a short focal length is required, such as Figure 7 As shown, the control driver 42 pushes ...

Abstract

The invention relates to a lens structure, a camera, a terminal and a control method thereof, and a computer storage medium. The lens structure comprises a lens barrel, a driving piece and a flexiblelight-transmitting piece. The flexible light-transmitting piece is arranged in a light path in the lens barrel. The driving piece is used for driving the flexible light-transmitting piece to deform soas to change the focal length. The lens barrel comprises a light inlet and a light outlet. The light inlet is provided with a first lens, and the flexible light-transmitting piece is arranged on theinner side of the first lens. The terminal comprises the camera with the lens structure. Optical zooming is performed through the built-in structure of the lens so that the size of the lens can be reduced and the structure is reliable.

Description

technical field [0001] The present application relates to the technical field of terminals, and specifically relates to a lens structure, a camera, a terminal and a control method thereof, and a computer storage medium. Background technique [0002] With the rapid development of terminal technology, the functions of mobile terminals such as mobile phones and tablet computers have also been continuously improved, and have gradually become one of the commonly used tools in people's daily life and work. [0003] Due to the user's demand for selfie and external shooting, most current mobile terminal devices such as smartphones are equipped with front cameras and rear cameras at the same time. However, in order to meet the needs of zooming, existing solutions mainly use external zoom modules To change the focal length of the camera, there are problems of unreliable structure and large lens size. Contents of the invention [0004] In view of the above technical problems, the pr...
