Abstract:
1. A method for imaging an in vivo site comprising: in a swallowable capsule comprising a housing, the housing including at least an optical window and an optical system separated from the optical window; illuminating a gastrointestinal tract site in vivo via the optical window and not via the optical system, by using a plurality of illumination sources; imaging the gastrointestinal tract site using a CMOS imaging camera via the optical window and via the optical system, the imaging comprising: collecting remitted light onto pixels of the CMOS imaging camera, thereby generating an analog signal; processing and converting the analog signal to a digital signal; randomizing the digital signal by randomizing occurrences of 0 and 1 digital signals; transmitting the digital signal to a receiving system; and processing the transmitted signals to obtain images of the in vivo site.
