Method and system for automatic focus with self-calibration

摘要

A systems, article, and method to provide automatic focus with self-calibration.

主权项

1. A computer-implemented method of automatic focus with self-calibration for an imaging device, comprising:
having the same initial default SOC and EOC values as set on a plurality of imaging devices; obtaining lens position calibration data used to capture a plurality of frames of a video sequence or still photographs; calculating at least one of:
an updated start of controllability (SOC),an updated end of controllability (EOC),updated infinity position (INF),and depending, at least in part, on the lens position calibration data of the plurality of frames or still photographs; and using at least one of the updated SOC, EOC, and INF to update a range of possible lens positions to capture a frame or photograph.
