Figure 3. Block diagram of the capsule endoscope
system. In the first stage the capsule acquires the
images. The object is illuminated by the LED
illumination system, and the image is projected on the
imager by an optical system. The image is then
transmitted outside the body by means of the
transmitter and antenna. In the second stage
antennae array and the receiver collect the
transmitted signal. The received data is subsequently
processed and stored in the data storage by CPU. In
the third stage the date is retrieved from the recorder
and transferred to the Workstation for additional
processing and presentation on the display.
