A 360-degree 4K×2K panoramic video recording over smart-phones

A 4K×2K video processor supporting 360-degree video recording over the smart-phone is first-reported. Two 180° fisheye cameras are exploited to stitch the circle video into a panorama one. Fast stitching algorithms reused the neighboring pixel and reduce the unused operating area while keep high stitching quality, and therefore achieve 4K real-time recording over 2.5GHz octa-core ARM CPU and Power VR GPU.
