Patent US 11,636,656

Various implementations disclosed herein include devices, systems, and methods that create additional depth frames where a depth camera runs at a lower frame rate than a light intensity camera. Rather than upconverting the depth frames by simply repeating a previous depth camera frame, additional depth frames are created by adjusting some of the depth values of a prior frame based on the RGB camera data (e.g., by “dragging” depths from their positions in the prior depth frame to new positions for a new frame). Specifically, a contour image is generated, and changes in the contour image are used to determine how to adjust (e.g., drag) the depth values for the additional depth frames. The contour image may be based on a mask (e.g., occlusions masks identifying where the hand occludes the virtual cube).
