Patent ID: 11887283
Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 0:
1. A device, comprising:
a memory;
one or more image capture devices; and
one or more processors operatively coupled to the memory, wherein the one or more processors are configured to execute instructions causing the one or more processors to:
obtain an incoming image stream from at least one of the one or more image capture devices, wherein the incoming image stream comprises two or more images;
determine a set of geometric distortion corrections for a first image from the incoming image stream, wherein the first image has a first field of view (FOV);
determine a region of interest (ROI) in the first image, wherein the ROI comprises a location within the first image and a second FOV, wherein the second FOV is smaller than or equal to the first FOV, and wherein the ROI comprises a region within the first image that it is desired to focus a perspective distortion correction on;
determine a set of perspective distortion corrections for the first image based, at least in part, on the location and second FOV of the ROI;
determine a set of fisheye distortion corrections to apply to a perspective distortion corrected version of the first image based, at least in part, on the location and second FOV of the ROI; and
apply a combined distortion correction to the ROI of the first image based on:
the determined set of geometric distortion corrections; and
a combination of the determined set of perspective distortion corrections and the determined set of fisheye distortion corrections.
