An operation method of a multiple lenses system applied in an electronic device is provided. The multiple lenses system includes at least one first lens and at least one second lens. The operation method includes: selecting a present capturing mode from a plurality of capturing modes; obtaining a preview image; estimating a focus distance by obtaining a sharpness of an object's edge in the preview image; determining whether the focus distance crosses a threshold; and switching from the at least one first lens to the at least one second lens or switching from the at least one second lens to the at least one first lens to obtain the preview image if the focus distance crosses the threshold. An electronic device is also provided.

Multiple lenses system, operation method and electronic device employing the same

A multiple lenses system applied in an electronic device is provided. The multiple lenses system includes a camera module, a focus module, an image sensor and a processor. The camera module includes at least one macro lens, at least one functional lens and a focus distance threshold. The focus module focuses on an object to be captured and obtains a focus distance. The image sensor captures images cooperatively with the camera module. The processor compares the focus distance and the focus distance threshold. If the processor determines the focus distance crosses the focus distance threshold, then the processor triggers the camera module to switch between the at least one macro lens and the at least one functional lens for capturing images. An electronic device employing the multiple lenses system and an operation method thereof are also provided.
