Abstract: Visual content captured by an image capture device may be stabilized. A target depicted within visual content of a video may be identified manually by a user or automatically by a computing device. Dolly zoom visual content may be generated by using a viewing window to crop the visual content. The size and/or the position of the viewing window within the visual content may change based on size and/or the position of the target within the visual content. The combination of video stabilization, target tracking, and cropping of the visual content may produce the dolly zoom effect. The dolly zoom effect may compensate for the movement of the image capture device and work on video captured by an image capture device without optical zoom.

Abstract: Adaptive acquisition control including limited luminance motion blur reduction for image and video acquisition and processing includes obtaining a target gain value and a target exposure duration value by obtaining a current scene luminance value, obtaining a current maximum gain using the current scene luminance value, obtaining a current interpolated gain-exposure duration curve using the current maximum gain and a current angular speed value, and obtaining the target gain value and the target exposure duration value from the current interpolated gain-exposure duration curve in accordance with a current maximum exposure duration. Adaptive acquisition control including limited luminance motion blur reduction for image and video acquisition and processing includes obtaining a frame of a video in accordance with the target scene exposition data and outputting the video.
