Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media that support improved image signal processing, particularly in low-light or high dynamic range (HDR) scenes. The image processing techniques may include performing two automatic exposure control (AEC) operations, in which a first AEC operation targets obtaining good conditions for autofocus (AF) operation, and a second AEC operation follows the AF operation and targets obtaining good conditions for an image capture. The image processing techniques may also include communication between the AEC operations and AF operations to coordinate the operations by locking and releasing exposure levels and focus positions as part of the image signal processing. In one aspect, a processing technique may include an AF measuring statistics from target, coordinating with AEC, and performing interleaving of a lock-and-resume state machine to achieve better AF result in challenging low-light or HDR scenes while maintaining an overall image quality.

Abstract: Image processing performed on images captured with image capture devices may be used to improve upon some of the problems with images captured from devices, including images captured from devices with larger aperture lenses, and, in some particular examples, mobile devices with larger aperture lenses. Multiple images may be captured by the capture device and processing applied to generate a single image through fusing of the multiple images. One potential benefit obtained with fusion of multiple images is a single image with an effective depth of focus (DOF) larger than that available in a single image obtained from the capture device. The DOF of the fused image may be larger than a single image and/or may include multiple distinct in-focus focal distances, whereas a single image from a single capture device has only a single in-focus focal distance.

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: An apparatus configured for image processing comprises one or more processors configured to determine data associated with a distance between an object and the apparatus and determine a plurality of lens positions of a camera lens based on the data associated with the distance between the object and the apparatus. The one or more processors are further configured to determine, for each one of the plurality of lens positions, a respective focus value to generate a plurality of focus values. To determine, for each one of the plurality of lens positions, the respective focus value, the one or more processors are configured to determine, for each one of the plurality of lens positions, phase difference information. The one or more processors are further configured to determine a final lens position based on the plurality of focus values.
