Endoscopic imaging apparatus, endoscopic imaging system and method of using the same

An endoscopic imaging apparatus, comprising:

• a diagnostic imaging means,
• an external control device, and
• an ingestible capsule endoscope,
• wherein
• the external control device is configured to position and orientate the capsule in a target area;
• the diagnostic imaging means is included in the capsule endoscope for diagnostic imaging of a target area under the control of the external control device,
• the ingestible capsule endoscope
• having a front end and rear end, respectively fixed at two ends of an elongated capsule shell, and the front end, the rear end and the elongated capsule shell construct an enclosed housing, wherein the rear end has a flat surface configured to be placed next to the target area for diagnostic imaging;
• said capsule endoscope comprising
• a magnet, and the magnet and the diagnostic imaging means are included in the enclosed housing and work in conjunction with the external control device,
• the rear end of the housing is provided with a light transparent surface;
• a photographic camera, configured, in the enclosed housing, to take image and/or record video of the target area;
• a first light source for illumination of the target area, configured to work with the photographic camera or the diagnostic imaging means;
• a second light source and/or a third light source for illumination of the target area, configured for working with the diagnostic imaging means or the photographic camera;
• wherein the second and third light source surround the diagnostic imaging means which is next to an interior surface of the flat surface of the rear end;
• a first light blocking part, positioned between a first area of the rear end facing the diagnostic imaging means and a second area at the rear end facing the second light source;
• and
• a second light blocking part, positioned between the first area at the rear end corresponding to the diagnostic imaging means and a third area at the rear end facing to the third light source,
• wherein thickness of the first light blocking part and second light blocking part is equal to or greater than a thickness of the flat surface of the rear end.
