Abstract
Systems and methods for detecting, characterizing, and addressing the type of endoscope that is connected to the camera/light source based on the image size taken using that endoscope are disclosed. Once the type of endoscope is determined, the systems and methods can adjust at least one parameter of the camera/light source based on the determination of the type of endoscope that is being used.
Claims17
An endoscopic system comprising:
- one or more processors configured to:
- receive image data representing an image from a video camera coupled to an endoscope;
- segment the image into at least two sections;
- segment each of the at least two sections into a plurality of subsections;
- calculate a representative pixel value for each of the subsections, wherein calculating the representative pixel value for each of the subsections comprises calculating a single representative luminance for a plurality of pixels within each subsection;
- determine what type of endoscope is coupled to the video camera based on the representative pixels values for each of the subsections;
- and
- adjust a parameter of the video camera based on the type of endoscope, wherein the parameter comprises at least one of video gain level, sharpness level, camera shutter speed, or gamma level.
