What it does
Gets video from the tiny eyepiece of an endoscope to a big TV screen.
How it works
It’s a Raspberry Pi. Powered by an onboard battery. A camera rigidly attached to the endoscope feeding live video back to the raspberry pi. An ultrabright LED powered by the onboard battery, controlled by the Pi through a transistor, illuminating the endoscope image. Buttons on device to capture stills and manipulate settings. Real-time image processing on the Pi to illuminate dark areas and improve contrast. Wireless video transmission directly to a smartphone, tablet, or computer.
How it’s different
We don’t require additional hardware to process the video.
Back when all of the current video endoscopy systems were built, hardware did not exist that was both small enough to fit in the handheld device itself and powerful enough to process and transmit the video stream. This necessitated a “video box” to capture raw data from the handheld device, process it, and display it on screen.
The new Raspberry Pi 4 breaks this limitation. It is small enough to fit in the hand, yet powerful enough to do some real-time video processing right next to the camera. It can transmit video over wifi or Bluetooth directly to another device - no “video box” required.
Removing the video box has several benefits. Less hardware. Cost. These video boxes can cost upwards of $10,000. Screen agnosticism. With a video box, the user is restricted to the screen that is hard-wired to the box. When no box is needed, video can be streamed to any device through an app or website. Improved quality. Automatic on-device video recording and storing, and easy playback
