Abstract: Systems, methods, and devices for fluorescence imaging in a light deficient environment are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a controller comprising a processor in electrical communication with the image sensor and the emitter. The system is such that the controller synchronizes timing of the pulses of electromagnetic radiation during a blanking period of the image sensor. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of electromagnetic radiation between 770 nm and 790 nm and/or electromagnetic radiation between 795 nm and 815 nm.

Abstract: An illustrative apparatus may identify, in an image frame captured by an image capture system, an object region corresponding to a depiction of an object portrayed in the image frame. The apparatus may determine a frame auto-exposure value for the image frame by discounting the object region in the image frame. Based on the frame auto-exposure value, the apparatus may update one or more auto-exposure parameters for use by the image capture system to capture an additional image frame. Corresponding apparatuses, systems, and methods for managing auto-exposure of image frames are also disclosed.

Abstract: A device that can be used for in vivo fluorescence measurements by endoscopy or laparoscopy, including: an excitation light source illuminating an object, for example biological tissue, and inducing emission of emission light by the examined object, the emission light is, for example, a fluorescence light; a telemetry sensor emitting a telemetry light beam towards the object; a projector element to project the excitation beam and the telemetry beam directly on the object. The telemetry sensor can estimate a distance between the projector element and the object, which distance makes it possible to modulate intensity of the excitation light emitted by the object. When the object is biological tissue, this makes it possible to comply with illumination thresholds of biological tissue and to maintain an illumination of constant intensity. The projector element can be included at the end of a laparoscope or of an endoscope.
