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: In general, techniques are described regarding fusing or combining frames of image data to generate composite frames of image data. Cameras comprising camera processors configured to perform the techniques are also disclosed. A camera processor may capture multiple frames at various focal lengths. The frames of image data may have various regions of the respective frame in focus, whereas other regions of the respective frame may not be in focus, due to particular configurations of lens and sensor combinations used. The camera processor may combine the frames to achieve a single composite frame having both a first region (e.g., a center region) and a second region (e.g., an outer region) in focus.

Abstract: Aspects of the present disclosure relate to systems and methods for performing autofocus. An example device may include a processor and a memory. The processor may be configured to receive a first image captured by a camera, determine a first ROI for the first image, receive a second image captured by the camera after capturing the first image, determine a second ROI for the second image, compare the first ROI and the second ROI, and delay a determination of a final focal length based on the comparison of the first ROI and the second ROI.
