Abstract:
Techniques to improve a digital image capture device's ability to stabilize a video stream are presented. According to some embodiments, improved stabilization of captured video frames is provided by intelligently harnessing the complementary effects of both optical image stabilization (OIS) and electronic image stabilization (EIS). In particular, OIS may be used to remove intra-frame motion blur that is typically lower in amplitude and dominates with longer integration times, while EIS may be used to remove residual unwanted frame-to-frame motion that is typically larger in amplitude. The techniques disclosed herein may also leverage information provided from the image capture device's OIS system to perform improved motion blur-aware video stabilization strength modulation, which permits better video stabilization performance in low light conditions, where integration times tend to be longer, thus leading to a greater amount of motion blurring in the output stabilized video.
