    Abstract: An optical path switching method is applied to a surveillance module. The method includes: determining a target magnification; and (i) when the target magnification is less than or equal to a maximum magnification of a camera, setting a magnification of the camera to the target magnification, determining that a reflection element is at a first location or in a first working state, and performing image capture by using the camera alone; or (ii) when the target magnification is greater than a maximum magnification of the camera, setting a magnification of the camera to a first magnification, determining that the reflection element is at a second location or in a second working state, and performing image capture by using both the camera and a teleconverter, where a product of the first magnification and a magnification of the teleconverter is the target magnification. The method increases a surveillance distance while reducing costs.

    Abstract: This application provides a compact camera module, which includes a first actuator, an optical lens component, a ray adjustment component, and an image sensor. The ray adjustment component and the image sensor are sequentially disposed along a direction of a principal optical axis of the optical lens component. The optical lens component is configured to receive rays from a photographed object. The ray adjustment component is configured to fold an optical path of the rays propagated from the optical lens component. The first actuator is configured to drive the ray adjustment component to move, so that the rays whose optical path is folded are focused on the image sensor.

    Abstract: This application provides a lens module and a lens module control method to implement, among other features, automatic focusing and improve image definition. The lens module includes an imaging lens, a first control module, a first processing module, a liquid lens, and an image chip. The liquid lens is configured to refract an imaging beam that comes from the imaging lens, and the liquid lens comprises a transparent first flat lens and a transparent second flat lens that are parallel to each other. The first control module is configured to adjust a distance between the first flat lens and the second flat lens. The first processing module is configured to adjust a distance between the first flat lens and the second flat lens by using the first control module and based on a definition of the digital image, so as to adjust the definition of the image generated by the image chip.

    Abstract: An embodiment of the present invention discloses an image processing method, an apparatus, and a device. The method is applied to a terminal having two specially manufactured cameras. A first sub-image that is of a to-be-photographed object and that is photographed by a first camera is obtained, where a corresponding field-of-view range is [0, θ1]; a second sub-image that is of the to-be-photographed object and that is photographed by a second camera is obtained, where a corresponding field-of-view range is [θ2, θ3], and quality of the first sub-image and the second sub-image satisfies a definition requirement of an extra-large aperture; and the first sub-image and the second sub-image are spliced and fused to obtain a target image that has a larger field-of-view range and satisfies the extra-large aperture.

    Abstract: A monitoring and photographing module includes one primary camera and N secondary cameras. The primary camera and the N secondary cameras are configured to collect images, and a frame rate at which any secondary camera collects an image is less than a frame rate at which the primary camera collects an image. Regions monitored by the N secondary cameras respectively cover N different regions in a region monitored by the primary camera, and a focal length of any secondary camera is greater than a focal length of the primary camera.
