| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Fiber Optics (fiber_optics) | enabling | 78% | review | Flexible fiber-optic endoscopy was the clinical optical platform that preceded and enabled electronic video endoscopy. |
|
| Digital Photography (CCD/CMOS Sensors) (digital_photography_ccd_cmos_sensors) | required | 88% | review | The first video endoscopes depended on miniaturized CCD image sensors that converted the distal optical image into an electronic video signal. |
