摘要： A camera assembly includes a time-of-flight module and a circuit board. The circuit board is provided with an avoidance space. The time-of-flight module includes a transmit module and a receive module. The transmit module is configured to emit a detection optical signal. The receive module is configured to receive an induction optical signal formed after the detection optical signal is reflected by a to-be-measured object. The receive module is located in the avoidance space. A connection end of the receive module is fixed to the circuit board. The transmit module is located around the receive module and fixed to the circuit board.

摘要： A camera system includes a module frame, a camera lens, an image sensor, and an SMA motor that are stacked within the module frame. The camera lens is fixedly connected to the module frame, and the SMA motor is located on an out-light side of the camera lens. The image sensor is located between the camera lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift in a direction parallel to an optical axis of the camera lens. The SMA motor is further configured to actuate the image sensor to shift on a plane perpendicular to the optical axis of the camera lens.

摘要： This application discloses a long-focus lens, a camera module, and an electronic device. The long-focus lens includes a first lens assembly, a second lens assembly, and a third lens assembly that are arranged from an object side to an image side. The first lens assembly and the third lens assembly are fixed lens assemblies, and the second lens assembly is a focusing lens assembly. In a focusing process in which the long-focus lens is switched from a long shot to a close-up, the second lens assembly moves toward the object side along an optical axis, a combined focal length of the first lens assembly and the second lens assembly decreases, and a combined focal length of the second lens assembly and the third lens assembly decreases. The foregoing long-focus lens has a strong focusing capability and high imaging quality.

摘要： A camera assembly includes an infrared laser system, a camera, a flicker detector, and a light-filtering piece. The infrared laser system has an out-light surface. Infrared emitted by the infrared laser system propagates outside of the camera assembly through the out-light surface. The out-light surface of the infrared laser system, an in-light surface of the camera, and an in-light surface of the flicker detector face a same direction and are staggered from each other. The light-filtering piece covers the in-light surface of the flicker detector and is configured to filter out infrared. The flicker detector is configured to detect a frequency of visible light in external light filtered by the light-filtering piece. When the camera assembly is applied to an electronic device, photographing performance of the electronic device is good.
