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: This disclosure provides systems, methods, and devices for image signal processing that support efficient motion estimation. In a first aspect, a method of image processing includes determining first and second sets of correlation parameters for respective first and second frames, generating a transform matrix indicating motion from the first frame to the second frame in accordance with the correlation parameters, and inverting the transform matrix to produce an inverted transform matrix. Other aspects and features are also claimed and described.
