1. An imaging system comprising: a plurality of diodes, a first subset of the plurality of diodes configured to capture image information representing a scene; a second subset of the plurality of diodes configured to capture phase detection information; and a processor configured with instructions to analyze the image information to identify a level of blurriness of a region of interest, determine a phase difference between at least first and second images generated based on the phase detection information, determine whether the phase difference exceeds the level of blurriness, and in response to determining that the phase difference does not exceed the level of blurriness, calculate an autofocus adjustment based on the phase difference.
