Abstract: 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.

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: 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: 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. The apparatus may determine one or more of a signal auto-exposure value of the signal region or a background auto-exposure value of the background region. Based on one or more of the signal auto-exposure value or the background auto-exposure value, the apparatus may determine a frame auto-exposure value. Additionally, based on the frame auto-exposure value, the apparatus may adjust one or more auto-exposure parameters used 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: An illustrative apparatus may determine a color-skew metric for an image frame captured by an image capture system. The color-skew metric may be indicative of an extent to which the image frame skews to a particular color. Based on the color-skew metric and an adaptive target control function, the apparatus may determine a frame auto-exposure target. Based on the frame auto-exposure target, 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: 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.

Abstract: An illustrative apparatus may perform gaze-based auto-exposure management of images. For example, the apparatus may determine, for an image captured by an image capture system, auto-exposure-related characteristics of pixel units into which the image is divided. The apparatus may update, based on the auto-exposure-related characteristics determined for the pixel units and on eye tracking data for a viewer viewing the image, one or more auto-exposure parameters for use by the image capture system to capture an additional image within an image sequence. Corresponding apparatuses, systems, and methods for gaze-based auto-exposure management of images are also disclosed.

Abstract: An illustrative apparatus may perform gaze-based auto-exposure management of image frames. For example, the apparatus may determine, for an image frame within an image frame sequence captured by an image capture system, auto-exposure values for pixel units into which the image frame is divided. The apparatus may then assign weight values to the pixel units based on a gaze direction of a viewer viewing the image frame sequence. Based on the auto-exposure values determined for the pixel units and the weight values assigned to the pixel units, the apparatus may update one or more auto-exposure parameters for use by the image capture system to capture an additional image frame within the image frame sequence. Corresponding apparatuses, systems, and methods for gaze-based auto-exposure management of image frames are also disclosed.
