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.
