1. An autonomous in-vivo device comprising:
- a housing having a longitudinal axis of symmetry;
an image sensor positioned in said housing to acquire images through a window in said housing; and
a ballast located off the longitudinal axis of symmetry, so that said device has a center of gravity displaced from the longitudinal axis of symmetry toward said window, such that the device rests in a known orientation.

Abstract
An in-vivo imaging device including a ballast that may for example orient such device in a known orientation relative to the gravitational force on such ballast. Such imaging device may, for example, assume a known orientation when it is free to move, and may capture images from such known orientation. The device may include one or more imagers, which may be oriented at different angles or points of view (e.g., forward and transverse). A method of use may include moving a patient so that the device inside the patient images different fields of view.

32. A method of in vivo imaging, comprising:
- orienting an autonomous in-vivo imaging device with a ballast, wherein said device has a housing having a longitudinal axis of symmetry with said ballast being located off the longitudinal axis of symmetry and causing a center of gravity of the device to be displaced from the longitudinal axis of symmetry in the direction of an in vivo area to be imaged, such that the device rests in a known orientation; and
capturing an image of an in-vivo area perpendicular to the longitudinal axis of symmetry of the device, wherein said ballast is on substantially the same side of the longitudinal axis of the device as the in vivo area imaged. - View Dependent Claims (33, 34, 35)
