An energy saving device for acquiring in vivo images of the gastro-intestina l tract is provided. The device, such as an autonomous capsule (10), includes at least one imaging unit (12), a control unit (14) connected to the imaging unit, and a power supply (24) connected to the control unit. The control unit includes a switching unit (18, 20), an d an axial motion detector (22) connected to the switching unit. The axial motion detector detects the axial movement of the device and if th e axial acceleration is below a pre-determined threshold, disconnects the power supply thereby preventing the acquisition of redundant images.
