1. A method comprising:
accessing a pair of corresponding images that depict an object captured by a pair of optical sensors that include a first optical sensor and a second optical sensor;
determining based on the pair of optical sensors a first Phase Detection Autofocus (PDAF) value of the object based on a first image from among the pair of corresponding images captured by the first optical sensor, and a second PDAF value of the object based on a second image from among the pair of corresponding images, captured by the second optical sensor;
generating an average PDAF value based on an aggregation the first PDAF value, derived based on the first image captured by the first optical sensor and the second PDAF value, derived based on the second image captured by the second optical sensor;
performing a comparison of the average PDAF value with a threshold value; and
providing an output value based on the comparison.
