    Abstract: An illustrative system may include an imaging device and an image processing system. The imaging device may be configured to output first image information corresponding to a first wavelength band associated with fluorescence emitted by a substance and may be configured to output second image information corresponding to a second wavelength band different from the first wavelength band and associated with the fluorescence emitted by the substance. The image processing system may be configured to receive the first image information and the second image information from the imaging device and may determine, based on a comparison of the first image information to the second image information, a property of the substance.

    Abstract: An exemplary medical imaging system includes a visible light illumination system configured to selectively emit one of a first visible light biased to a first wavelength and a second visible light biased to a second wavelength, a fluorescence excitation illumination system configured to selectively emit one of a first fluorescence excitation illumination having a third wavelength and a second fluorescence excitation illumination having a fourth wavelength, and an illumination source control unit configured to selectively direct the visible light illumination system to emit the second visible light and the fluorescence excitation illumination system to emit the first fluorescence excitation illumination for use with a first fluorescence imaging agent, and selectively direct the visible light illumination system to emit the first visible light and the fluorescence excitation illumination system to emit the second fluorescence excitation illumination for use with a second fluorescence imaging agent.

    Abstract: A stereoscopic image capture device includes a first image sensor, a second image sensor, a first frame timer, and a second frame timer. The first and second frame timers are different frame timers. The first image sensor includes a first plurality of rows of pixels. The second image sensor includes a second plurality of rows of pixels. The first and second image sensors can be separate devices or different areas of a sensor region in an integrated circuit. The first frame timer is coupled to the first image sensor to provide image capture timing signals to the first image sensor. The second frame timer coupled to the second image sensor to provide image capture timing signals to the second image sensor.

    Abstract: A system includes an image sensor, an imaging pipeline, and a display device. The image sensor is configured to capture a first frame of pixel data. The imaging pipeline is coupled to the image sensor to receive the first frame of pixel data. The imaging pipeline includes an adaptive noise filter. The adaptive noise filter is configured to filter a pixel based on noise in the pixel. The imaging pipeline is configured to output a second frame of pixel data. The second frame of pixel data includes pixels filtered by the adaptive noise filter. The display device is coupled to the imaging pipeline to receive the second frame of pixel data. The display device being configured to display the second frame of pixel data.

    Abstract: A system directs an imaging device to continuously capture visible light and fluorescence illumination from a surgical area. The system generates a visible light image stream based on the captured visible light and a fluorescence image stream based on the captured fluorescence illumination. The system operates in a first display mode by directing a display device to display a first video stream based on a first set of at least one of the visible light image stream and the fluorescence image stream. In response to detecting an event that occurs within the surgical area, the system switches from operating in the first display mode to operating in a second display mode by directing the display device to display a second video stream based on a second set of at least one of the visible light image stream and the fluorescence image stream, the first Instructions set being different than the second set.

    Abstract: An illustrative apparatus may identify, within an image frame captured by an image capture system, a signal region of the image frame and a background region of the image frame; determine one or more of a signal auto-exposure value of the signal region or a background auto-exposure value of the background region; and adjust, based on one or more of the signal auto-exposure value or the background auto-exposure value, one or more auto-exposure parameters used by the image capture system to capture an additional image frame. The identifying of the signal region and the background region may include identifying pixels of the image frame that have auto-exposure values that exceed an auto-exposure value threshold to be included within the signal region, and identifying pixels of the image frame that have auto-exposure values that do not exceed the auto-exposure value threshold to be included within the background region.
