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.

Abstract: Systems and techniques are provided for processing one or more images. For instance, aspects include a process that can include determining a first region of interest corresponding to a first object depicted in an image obtained using at least one camera. The first region of interest is associated with at least one element of a multi-point grid associated with a multi-point depth sensing system. The process can include determining a first extended region of interest for the first object. The first extended region of interest is associated with a plurality of elements including the at least one element and one or more additional elements of the multi-point grid. The process can further include, based on the plurality of elements associated with the first extended region of interest, determining representative depth information representing a first distance between the at least one camera and the first object depicted in the image.

Abstract: Aspects of the present disclosure relate to systems and methods for image focusing for devices including multiple cameras. An example method includes estimating a focus distance associated with an image captured by a first camera, determining, based at least in part on the estimated focus distance, to switch from the first camera to a second camera, switching from the first camera to the second camera, completing a focusing operation using the second camera and presenting an updated image captured by the second camera.

Abstract: Techniques and systems are provided for improving one or more image capture operations. In some examples, a system determines, based on data from one or more sensors, a movement of an image capture device associated with a capture of a plurality of image frames. The systems adjust a position of at least one object in each of the plurality of image frames based on the movement of the image capture device. The system determines a motion of the at least one object based on a difference in the adjusted position among the plurality of image frames. The system selects a value for at least one image capture parameter associated with the plurality of image frames based on the motion of the at least one object.
