Lens capable of changing shooting direction, and operating method thereof

Abstract

The invention relates to a lens capable of changing shooting direction, and an operating method thereof. The lens comprises a lens assembly mounting seat and an optical lens assembly; a light guiding cavity is formed in the lens assembly mounting seat in front of the optical lens assembly and extend along different directions to form at least two light guide grooves; and light through holes are formed in the end portions of the light guide grooves. In addition, the lens also includes a light guide switching device having a light guide element movably arranged in the light guiding cavity; and the light guide switching device is started, so that the light guide element selects to receive an image from one light though hole and guides the image into the optical lens assembly. The operating method is applied to the lens. The lens having a simple structure can be operated conveniently and rapidly.

Description

Technical field: [0001] The present invention relates to the field of optical imaging, in particular to a lens used for changing shooting directions on a handheld mobile device and an operating method thereof. Background technique: [0002] Existing handheld mobile devices, such as mobile phones and tablet computers, are usually equipped with two cameras, the front and the back. For selfies or video sessions (commonly known as secondary camera). According to the user's usage habits and needs, the pixels and image quality of the camera on the back of the product are usually better than those on the front of the product. [0003] For users who like to take selfies or have high requirements for selfies, the pixels of the camera on the front of the product often cannot meet the requirements, and there are usually problems such as low shooting resolution and excessive noise. If the user uses the camera on the back of the product to take pictures, although the above problems can...

Problems solved by technology

[0003] For users who like to take selfies or have high requirements for selfies, the pixels of the camera on the front of the product often cannot meet the requirements, and there are usually problems such as low shooting resolution and too many noise points.

If the user uses the camera on the back of the product to take pictures, although the above problems can be avoided, the user cannot intuitively see the shooting angle, shooting range and own expression when taking selfies, and it is difficult to take ideal results

[0004] And with the popularization of touch-screen mobile phones and tablet computers, most of the shutter buttons are virtual buttons, which are located in the shooting control screen on the product screen. When using the rear camera to shoot, because the user cannot see the control screen on the product screen, it cannot Click the shutter button, there is a possibility of misoperation, which brings great inconvenience to the camera operation

[0005] At the same time, when conducting a video conversation, although mobile phones and tablet computers have high-resolution cameras on the back, if they want to see the image sent by the other user, the user must be talking to the mobile phone or tablet computer.

The resources of mobile phones and tablet computers cannot be fully and effectively utilized; using the front camera, the clarity of the picture received by the other party user is also very limited

[0006] Installing two cameras on the front and back also increases the production cost of the manufacturer, and correspondingly increases the risk of product failure
