Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to provide for improved perspective distortion correction for wide field of view (FOV) video image streams. The techniques disclosed herein may be configured, such that the distortion correction applied to requested region of interest (ROI) portions taken from individual images of the wide FOV video image stream smoothly transitions between applying different distortion correction to ROIs, depending on their respective FOVs. In particular, the techniques disclosed herein may modify the types and/or amounts of perspective distortion correction applied, based on the FOVs of the ROIs, as well as their location within the original wide FOV video image stream. In some cases, additional perspective distortion correction may also be applied to account for tilt in an image capture device as the wide FOV video image stream is being captured and/or the unwanted inclusion of “invalid” pixels from the wide FOV image.

Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to provide improved region of interest (ROI) tracking, image framing, and distortion correction for wide field of view (FOV) video image streams. The techniques disclosed may be configured, such that the image framing decisions made over the course of a captured wide FOV video image stream are able to be panned smoothly and seamlessly transition between framing a narrower portion of a wide angle camera's FOV to framing a wider portion of the wide angle camera's FOV (or vice versa), e.g., depending on the composition and movement of relevant subjects in the captured scene. The techniques disclosed herein may also be used to perform any distortion correction desired on the framed image portions in the output video image stream, e.g., based on the image portions' FOVs and/or the locations of the portions within the original wide FOV video image stream.
