Abstract: Systems and methods for rapid automatic focus, automatic white balance, and automatic exposure control are disclosed. To reduce the time it takes to automatically focus, balance spectra, and set exposure period, a dual camera uses an auxiliary camera and auxiliary image processing module in addition to the main camera and main image processing module. The auxiliary camera may capture lower resolution and lower frame rate imagery that is processed by an auxiliary image processing module to determine focus, white balance, and exposure periods for the main camera and main image processing module. By initiating convergence for automatic focus (AF), automatic white balance (AWB) and automatic exposure control (AEC) before receiving a command to capture imagery, and processing lower resolution and lower frame rate imagery, AF, AWB, and AEC convergence delays are reduced for both standard and high dynamic range image capture.

Abstract: An image capture device that includes an adjustment circuit configured to monitor image parameters, generate updated image settings for the image capture device in response to the monitored image parameters, and transmit the updated image settings to one or more processors. The updated image settings configure the one or more processors to determine whether to transition the image capture device from a dynamic scene mode to a static scene mode based on a first image parameter included in the monitored image parameters, wherein the first image parameter is different from a second image parameter used to determine to transition the image capture device from the static scene mode to the dynamic scene mode, and to suspend generation of all or less than all of the updated image settings in response to determining to transition the image capture device from the dynamic scene mode to the static scene mode.
