In vivo imaging device with a small cross sectional area
First Claim
Patent Images
1. An in vivo imaging device, comprising:
- a capsule shaped housing having a longitudinal axis and an optical window at an end of the housing;
a CMOS image sensor comprising a pixel array portion and a circuitry portion, wherein said pixel array portion is disposed within said housing substantially parallel to said longitudinal axis;
a light deflecting element for deflecting received light to said pixel array portion, wherein the angle between said light deflecting element and said pixel array portion is smaller than 45°
thereby distorting an image projected onto said pixel array portion; and
a mechanism to compensate for said distortion.

Abstract
An in vivo imaging device may include a capsule shaped housing and an image sensor. The capsule shaped housing may have a longitudinal axis and a window. The image sensor (e.g., a CMOS sensor) may include a pixel array portion and a circuitry portion. The circuitry portion may be segregated, for example longitudinally, from the pixel array portion. The pixel array portion may be disposed within said housing substantially parallel to said longitudinal axis.
A light deflecting element disposed at an angle smaller than 45 degrees with respect to the pixel array portion introduces image distortion which is compensated by a distortion compensation mechanism.
