An imaging module, including a substrate, a sensor assembly, a lens assembly and an adjustable lens assembly. The sensor assembly is arranged on the substrate and is configured to receive light passing through the adjustable lens assembly and the lens assembly. The adjustable lens assembly includes a piezoelectric actuator and an adjustable lens, and the piezoelectric actuator is configured to deform the adjustable lens through the action of an electrical signal and change a focal length of the imaging module.
