ENDOSCOPIC CAMERA ILLUMINATION SYSTEM AND METHOD

摘要

An endoscopic camera system (10) having a camera head (12) with an imaging device (18) for capturing images during an exposure period at a predetermined number of frames per second; an illumination system (20) for providing illumination for the imaging device; and a camera control unit (14) coupleable to the camera head; the camera control unit (14) having a controller (48) for supplying a drive current to the illumination system (20), the controller (48) altering the drive current to the illumination system (20) so that the illumination system receives a reduced drive current or no drive current for a portion of each image frame; and an image processor (58) that alters image processing based on an amount of drive current received by the illumination system (20) during a frame.
