An exemplary image capturing unit includes a housing, a moveable support, and a driving assembly. The moveable support is moveably mounted in the housing. The moveable support includes a rotating axis and is configured for receiving a camera module. The driving assembly includes a first magnetic member and a second magnetic member. The first magnetic member is positioned on the housing. The second magnetic member is positioned on the moveable support and faces the first magnetic member. The driving assembly is configured for driving the moveable support to rotate about the rotating axis relative to the housing through magnetical interaction between the first magnetic member and the second magnetic member.
