For example, an imaging sensor array includes a number of physical PDAF sensors that provide a PDAF resolution that is a small percentage of the resolution of the imaging sensor itself. The PDAF resolution is upsampled without relying on adding physical PDAF sensors by generating simulated PDAF sensors at upsampling locations. For each upsampling location, embodiments can compute local disparity values and local contrast values for each of multiple neighboring physical PDAF sensors. An upsampled disparity value can be computed for the upsampling location by weighting the neighboring local disparity values based at least on the neighboring local contrast values. The upsampled disparity values can yield higher-resolution information for use in PDAF operations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Real-time disparity upsampling for phase detection autofocus in digital imaging systems","description":"Techniques are described for real-time disparity upsampling for phase detection autofocus (PDAF) in digital imaging systems.
