Abstract
An energy saving device for acquiring in vivo images of the gastro-intestinal 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), and an axial motion detector (22) connected to the switching unit, disconnects the power supply thereby preventing the acquisition of redundant images.
