Abstract: The present disclosure generally relates to exposure control for image capture devices. One example method generally includes receiving sensor data indicating a movement associated with an image capture device capturing a first frame and a second frame, wherein the first frame is associated with a higher exposure setting as compared to the second frame; predicting, based on the sensor data, a shift for aligning one or more features of the first frame and one or more features of the second frame; applying the shift to align the one or more features of the first frame and the one or more features of second frame; and generating a frame output at least in part by combining at least a portion of the first frame with at least a portion of the second frame.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. A method of processing image data includes capturing an image associated with a first exposure; capturing a plurality of images associated with at least a second exposure, the second exposure being less than the first exposure; generating a combined image from the plurality of images associated with at least the second exposure; and generating a high dynamic range (HDR) image from the image associated with the first exposure and the combined image.

Abstract: Image frames for computational photography may be corrected, such as through rolling shutter correction (RSC), prior to fusion of the image frames to reduce wobble and jitter artifacts present in a video sequence of HDR-enhanced image frames. First and second motion data regarding motion of the image capture device may be determined for times corresponding to the capturing of the first and second image frames, respectively. The rolling shutter correction (RSC) may be applied to the first and second image frames based on both the first and second motion data. The corrected first and second image frames may then be aligned and fused to obtain a single output image frame with higher dynamic range than either of the first or second image frames.

Abstract: Methods, systems, and devices for anchor frame switching in an imaging system are described. A device may generate a pixel map based on a set of frames. A first subset of frames of the set of frames have a first exposure and a second subset of frames of the set of frames have a second exposure different than the first exposure. The device may determine a region of the pixel map representing motion between at least two frames of the first set of frames. If the device determines that a quantity of motion pixels in the region is higher than a threshold, the device may select a short exposure frame as an anchor frame, beginning at a later frame. Otherwise, the device may maintain using a long exposure frame as the anchor frame.

Abstract: Systems and methods for synchronizing frame captures for cameras with different fields of capture are described. An example device includes a first camera and second camera. The first camera includes a first camera sensor and a first rolling shutter. The first camera is configured to prevent scanning pixels from a first row to a row n of the first camera sensor and configured to begin sequentially scanning pixels of the row n of the first camera sensor. The second camera includes a second camera sensor and a second rolling shutter. The second camera is configured to begin sequentially scanning pixels of a first row of the second camera sensor concurrently with beginning to sequentially scan pixels of the row n of the first camera sensor. The first row of the second camera sensor corresponds to a row within a predefined number of rows after the first camera sensor's row n.

Abstract: A stereoscopic imaging device is configured to capture multiple corresponding images of objects from a first camera and a second camera. The stereoscopic imaging device can determine multiple sets of keypoint matches based on the multiple corresponding images of objects, and can accumulate the keypoints. In some examples, the stereoscopic imaging device can determine a vertical disparity between the first camera and the second camera based on the multiple sets of keypoint matches. In some examples, the stereoscopic imaging device can determine yaw errors between the first camera and the second camera based on the sets of keypoint matches, and can determine a yaw disparity between the first camera and the second camera based on the determined yaw errors. The stereoscopic imaging device can generate calibration data to calibrate one or more of the first camera and the second camera based on the determined vertical disparity and/or yaw disparity.

An example device may include one or more processors. The example device may also include a memory coupled to the one or more processors and including instructions that, when executed by the one or more processors, cause the device to receive a plurality of corresponding images of scenes from multiple cameras during normal operation, accumulate a plurality of keypoints in the scenes from the plurality of corresponding images, measure a disparity for each keypoint of the plurality of keypoints, exclude one or more keypoints with a disparity greater than a threshold, and determine, from the plurality of remaining keypoints, a yaw for a camera of the multiple cameras.
