    Abstract: 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.

    Abstract: A two-by-two pixel array within an image sensor includes a first pixel, a second pixel, a third pixel, and a fourth pixel. A red filter covers the first pixel, a first blue filter covers the second pixel, a second blue filter covers the third pixel, and a green filter covers the fourth pixel. The red filter is configured to allow the first pixel to collect a red component of visible light and prevent the first pixel from collecting blue and green components of the visible light. The first and second blue filters are configured to allow the second and third pixels to each collect the blue component and prevent the second and third pixels from collecting the red and green components. The green filter is configured to allow the fourth pixel to collect the green component and prevent the fourth pixel from collecting the red and blue components.

    Abstract: An illustrative apparatus maps a first color of a first image of a scene to a second color of a second image of the scene. The first color of the first image is defined by a combination of real primary colors of a first display technology. The second color of the second image is determined by mapping at least one of the real primary colors of the first display technology to at least one virtual primary color for a second display technology and using the at least one virtual primary color to define the second color of the second image. The at least one virtual primary color is different from real primary colors of the second display technology.

    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 includes a controller communicatively coupled to an illuminator and to a camera configured to capture a scene including tissue. The controller may change the output optical power of the illuminator from a first output optical power to a second output optical power so that a subsequently captured frame is captured by the camera from reflected light, the reflected light being light from the illuminator having the second output optical power prior to being reflected. The controller may determine that an endoscope contacted the tissue if the change of the output optical power of the illuminator results in a change of a reflected luminance that is less than a predetermined threshold, the change of the reflected luminance being a change from a first reflected luminance for the first output optical power to a second reflected luminance for the second output optical power.
