Resolving Near-Field Blur on iPhone Pro Max via Camera Switching and Microscopy Capability
The iPhone 13/14 Pro Max near‑field blur was fixed by the Paizhil Tao team by replacing the deprecated AVCaptureDevice call with AVCaptureDeviceDiscoverySession, calibrating videoZoomFactor thresholds and leveraging the virtualDeviceSwitchOverVideoZoomFactors API to automatically switch between wide, telephoto and ultra‑wide lenses under suitable zoom, lighting and focus conditions, thereby restoring close‑up image clarity and boosting recognition performance.
