Patent Images
1. A method for calculating a size of an object in vivo using images acquired by an imager, the method comprising:
- determining a distance traveled by said imager during capture of two of said images;
calculating relative spatial coordinates of a set of objects within said images using said distance; and
calculating the size of one of the set of objects from said spatial coordinates;
wherein the above steps are performed by a processor.

Abstract
A device, system and method for calculating a size of an object using images acquired by a typically moving imager, for example in the gastrointestinal (GI) tract. A distance traveled by the moving imager during image capture may be determined, and spatial coordinates of image pixels may be calculated using the distance. The size of the object may be determined, for example, from the spatial coordinates. The moving imager may be in a swallowable capsule, or, for example, an endoscope.

10. A swallowable capsule comprising:
-
an image sensor capable of obtaining images from within the gastrointestinal tract; a distance-detecting sensor capable of generating data for determining a distance traveled by said capsule during reception of at least two of said images, wherein said data may be used by a processor for generating spatial coordinates of at least one object found within said two images and for converting said spatial coordinates into a size calculation of said at least one object. - View Dependent Claims (11, 12, 13)
