Optical lens, camera module, and terminal

An imaging device, comprising a photosensitive element, a driver, and an optical lens,

• wherein the optical lens comprises a first component, a second component, a third component, and a fourth component that are successively arranged from an object side to an image side and each comprise at least one lens,
• the second component comprises a refraction member configured to change a transmission route of light transmitted from the first component by refraction, wherein the refraction member is disposed within the second component and located on a side of the second component facing away from the third component,
• the third component and the fourth component are coaxially disposed along a common optical axis, wherein the common optical axis is aligned with a refracted path of the light transmitted from the first component after refraction by the second component,
• an included angle is formed between optical axes of the third component and the fourth component and an optical axis of the first component,
• a position of the second component relative to an imaging plane of the optical lens is fixed, and
• the first component, the third component, and the fourth component are configured to move relative to the second component, so that the optical lens transitions between a long-focus state, a medium-focus state, a wide-angle state, and a micro-focus state, wherein the micro-focus state corresponds to a state in which a focal length of the optical lens is smaller than that in the wide-angle state;
• wherein the photosensitive element is located on an image side of the optical lens and is located on an imaging plane of the optical lens, and the driver is configured to drive the first component, the third component, and the fourth component to move relative to the second component,
• wherein, when the optical lens performs zooming from the wide-angle state to the long-focus state, the second component does not move, and the first component, the third component, and the fourth component move toward the object side, and
• wherein, when the optical lens performs zooming from the wide-angle state to the micro-focus state, the second component does not move, the first component moves toward the image side, and the third component and the fourth component move toward the object side.

A terminal, comprising an image processor and a camera module, wherein the image processor is communicatively connected to the camera module, the camera module is configured to:

• wherein the camera module comprises a photosensitive element, a driver, and an optical lens,
• the optical lens comprises a first component, a second component, a third component, and a fourth component that are successively arranged from an object side to an image side and each comprise at least one lens,
