Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to perform predictive image sensor cropping operations to improve the performance of video image stabilization operations, especially for high resolution image sensors. According to some embodiments, the techniques include, for each of one or more respective images of a first plurality of images: obtaining image information corresponding to one or more images in the first plurality of images captured prior to the respective image; predicting, for the respective image, an image sensor cropping region to be read out from the first image sensor; and then reading out, into a memory, a first cropped version of the respective image comprising only the predicted image sensor cropping region for the respective image. Then, a first video may be produced based, at least in part, on the first cropped versions of the one or more respective images of the first plurality of images.

Abstract: A method of operating an image sensor includes determining a duration of an integration time for an image frame; operating an array of pixels to capture the image frame; receiving a decision to truncate the image frame; truncating the image frame before satisfying the duration of the integration time; and reading out a set of pixel values for the array of pixels. Each pixel in the array of pixels is exposed for a truncated integration time. The truncated integration time has a truncated duration shorter than the determined duration.
