## Abstract

An adapter for endoscopy can operably connect camera features and light source features of a portable electronic device with a respective viewfinder and illumination element of a medical endoscope. Systems including an endoscope, adapter, and handheld electronic device with a microphone, light source, and camera can, when connected, be used to perform stroboscopic endoscopic examinations.

a management component comprising a processor and memory containing instructions, the instructions operable to cause the management component to:
receive image data from the camera;
process the received image data to generate video data;
receive an output from the microphone corresponding to a patient's voice;
process the output from the microphone to determine a frequency of the patient's voice;
process the video data based on the frequency to generate diagnostic video data; and
cause the diagnostic video data to be displayed on the display.

### Claim 8 (depends on 7)

The system of claim 7, wherein the adapter further comprises: a light sensitive detector connected with the frame and aligned to receive light from the first light source and generate a signal; and a second light source operably connected with the light sensitive detector and coupled with an illumination element of the endoscope so that, when the first light source cycles, the second light source provides strobing illumination to the illumination element of the endoscope at the rate proximate to the frequency.
