摘要： An illustrative apparatus may identify, within an image frame captured by an image capture system, a signal region that includes pixels having auto-exposure values exceeding an auto-exposure value threshold. The apparatus may adjust, based on the auto-exposure values of the pixels included within the signal region, one or more auto-exposure parameters used by the image capture system to capture an additional image frame. Additionally, the apparatus may determine, based on a size of the signal region within the image frame, whether to change the auto-exposure value threshold. Corresponding apparatuses, systems, and methods for managing auto-exposure of image frames are also disclosed.

摘要： Technology described herein can be embodied in a method of displaying a visual representation of a portion of a surgical scene. The method includes receiving data representing information captured using a first sensor of a camera associated with a surgical device, the information being indicative of a first quantity representing an amount of fluorescence emitted from the portion of the surgical scene. The method also includes obtaining information indicative of a second quantity representing an amount of excitation signal causing the fluorescence to be emitted from the portion of the surgical scene, and generating a normalized fluorescence signal as a function of the first quantity and the second quantity. The method further includes generating the visual representation of the portion of the surgical scene based on the normalized fluorescence signal, and presenting the visual representation on a display device associated with the surgical device.

摘要： The technology described herein can be embodied in a method that includes receiving data representing information captured using a first sensor and a second sensor of a multi-sensor camera. The sensors are configured to capture a surgical scene illuminated by a light source configured to emit wavelengths in the visible spectrum corresponding to sensing capabilities of the first and second sensors, respectively. The method also includes receiving data representing information captured using a third sensor of the multi-sensor camera, the third sensor configured to capture the surgical scene as illuminated by a near-infrared light source, and generating a first visual representation of the surgical scene based on the data representing the information captured using the first and second sensors. The first visual representation is combined with the information captured using the third sensor to generate a second visual representation, and the second visual representation is presented on a display device.

摘要： An illustrative apparatus may obtain an image frame captured by an image capture system in accordance with an auto-exposure parameter set to a first setting. The image frame may include a first image component associated with visible light and a second image component associated with non-visible light. The apparatus may determine a first auto-exposure gain based on the first image component and may determine a second auto-exposure gain based on the second image component. Based on the first and second auto-exposure gains, the apparatus may determine a second setting for the auto-exposure parameter. The second setting may be configured to be used by the image capture system to capture a subsequent image frame. Corresponding apparatuses, systems, and methods for managing auto-exposure of multi-component image frames are also disclosed.

摘要： An example method includes determining an estimated pixel noise parameter based on a signal level of a first pixel of the first frame of pixel data; determining a difference between the signal level of the first pixel and at least a signal level of a second pixel; obtaining a filtered pixel based at least in part on a comparison of the difference to the estimated pixel noise parameter; and outputting the filtered pixel to an output frame of filtered pixel data.
