Zusammenfassung:A periodontal endoscope includes an imaging handle having an imaging end that supports a camera sensor and an introducer including an introducer blade such that the introducer blade is selectively rotatable about the camera sensor for engaging gingival tissue in the field of view for any rotational orientation of the introducer blade relative to the camera while illuminated by an optical fiber bundle. An automatic illuminance controller controls an illumination light source at least within each frame as the frame is scanned based on dynamic range of the camera sensor such that high intensity areas of the frame receive a reduced amount of illumination light by reducing the illumination drive signal as compared to low intensity areas of the frame which receive an increased amount of illumination light by increasing the illumination drive signal relative to the high intensity areas.
