Learning-Based Camera Autofocus Prediction for Sparse Phase Detection Imaging Sensors

A computing system comprising:

• a control system configured to:
• receive, from a plurality of sparse phase detection sensors, sparse phase detection sensor data;
• determine a disparity prediction and an associated confidence value based on the sparse phase detection sensor data;
• use the associated confidence value to determine an autofocus lens position for an image sensor based on the disparity prediction;
• and
• cause the image sensor to autofocus based on the determined autofocus lens position.

A non-transitory computer readable medium storing program instructions executable by one or more processors to cause the one or more processors to perform operations comprising:

• receiving, from a plurality of sparse phase detection sensors, sparse phase detection sensor data;
• determining a disparity prediction and an associated confidence value based on the sparse phase detection sensor data;
• using the associated confidence value to determine an autofocus lens position for an image sensor based on the disparity prediction;
• and
• causing the image sensor to autofocus based on the determined autofocus lens position.
