- Endoscopy relies on high-brightness illumination, usually located right next to the imaging system.
- A small increase in distance causes a large drop in light levels: close objects can be saturated and blown out while slightly further objects are too dark to see. This, clearly, flies in the face of the kind of detailed documentation and/or surgery that needs to happen under these conditions.
- amp captures the entire light range and, therefore, all the critical details with each video frame.
