Endoscope Low Light SPSD Image Sensor Patent
Summary
USPTO granted patent US12599294B2 to Schölly Fiberoptic GmbH for an image-recording device combining a single photon sensitive detector (SPSD) with a photodiode-based image sensor in an endoscope for improved low-light imaging. The dual-detection approach captures additional spectral information from a common object area to enhance image quality. The patent contains 24 claims and was filed on July 12, 2022.
What changed
USPTO granted patent US12599294B2 to Schölly Fiberoptic GmbH covering an endoscope with a single photon sensitive detector (SPSD) used alongside a conventional photodiode image sensor to capture enhanced image data in low-light conditions. The dual-detection system can capture additional spectral information from the same object area, improving overall imaging quality.\n\nManufacturers of endoscopic imaging equipment should review this patent when developing low-light imaging capabilities to assess potential infringement risks. Healthcare providers utilizing advanced endoscopic systems may benefit from improved visualization technologies resulting from this dual-sensor approach.

Abstract
In order to improve imaging, in particular for low light intensities, an image recording device, in particular formed as an endoscope, is proposed, which comprises a single photon sensitive detector (SPSD) in addition to an image sensor, which uses photodiodes as light-sensitive cells, in order to respectively detect light from a common object area. With the help of the SPSD, additional image information can be obtained from the object area, to improve the image data recorded with the image sensor or to enhance it with additional image information, in particular with regard to a further spectral range, which is captured with the SPSD.
