Systems and methods of adaptive phase detection autofocus offset correction

Abstract

Imaging systems and techniques are described. An imaging system receives image data captured by an image sensor according to one or more image capture settings, for instance according to an aperture size, temperature, lux, lens position, and/or region of interest. The image data includes image pixel data and focus pixel data. The imaging system determines a first focus setting based on phase detection using the focus pixel data. The imaging system determines a focus offset based on use of the one or more image capture settings as inputs to a trained model (e.g., decision tree, random forest, neural network). The imaging system determines a second focus setting at least in part by adjusting the first focus setting according to the focus offset, and causes a focus control mechanism to set a focus parameter to the second focus setting.
