Abstract: Examples are described of automatic exposure timing synchronization. An imaging system includes a first image sensor configured to capture a first image according to a first exposure timing, including by exposing first region of interest (ROI) image data at the first image sensor for a first ROI exposure time period. Based on the first exposure timing, the imaging system sets a second exposure timing for a second image sensor to capture a second image. Capture of the second image according to the second exposure timing includes exposure of second ROI image data at the second image sensor for a second ROI exposure time period. The second exposure timing may be set so that the start of the second ROI exposure time period aligns with the start of the first ROI exposure time period, and/or so that the first and second ROI exposure time periods overlap.

Abstract: An aspect of this disclosure is an apparatus for capturing an image. The apparatus comprises an image sensor configured to capture an image of a field of view. The apparatus also comprises a flash component configured to illuminate at least a portion of the field of view at a power level during capture of a first frame by the image sensor. The apparatus further comprises a controller. The controller is configured to determine a flash ramp-up time for the flash component, the flash ramp-up time corresponding to an amount of time between a flash being requested at the power level and the flash component producing the flash at the power level. The controller is also configured to blank the image sensor for a blanking period during the flash ramp-up time.

Abstract: Described herein are methods, apparatus, and computer readable medium to autofocus a lens of an imaging device. Parameters are received indicating a lens position. Lens actuator characteristics are determined. Lens damping parameters may be determined based, at least in part, on the input parameters and the lens actuator characteristics. In some aspects, lens damping parameters include a lens movement step size and a time delay between each step. In some aspects, the lens damping parameters include damping parameters for a plurality of regions of lens movement. Lens movement parameters are determined based, at least in part, on the input parameters and the lens damping parameters. The lens is then autofocused by moving it according to the lens movement parameters.

Abstract: Synchronization of settings for different camera components are described. An example device may include a memory and one or more processors coupled to the memory. The one or more processors may be configured to instruct, at a first time, application of a first setting corresponding to a first camera component. Application of the first setting may be associated with a first delay. The one or more processors may also be configured to determine, based on the first delay, a second time to instruct application of a second setting corresponding to a second camera component. The one or more processors may further be configured to instruct, at the second time, application of the second setting. Application of the first setting and application of the second setting are synchronized based on the first time and the second time.

Abstract: One innovation includes an imaging device having an image sensor, a lens having a movable optical element, and an actuator operative to move the one optical element to a plurality of lens positions. The imaging device further includes an electronic display, a power source electrically coupled to the camera system and to the display, the power source (e.g., voltage regulator) configured to provide power to the display and the camera system, a memory circuit configured to store information representing an actuator control value that corresponds to a low-power focus position, and an electronic hardware processor coupled to the memory circuit, the actuator and the electronic display. The processor may retrieve the actuator control value from the memory circuit and controls the actuator to move the optical element to the lens position that corresponds to the low-power focus position when the camera system is in a deactivated state.

Abstract: Example techniques are described for low power mode operation for multi-camera devices. A camera device includes processing circuitry configured to determine what information from the first camera is needed to process image content captured by the second camera or to operate the second camera, and adjust an operation mode of one of the first camera or camera circuitry coupled to the first camera from a first operation mode to a second operation mode based on the determination. An amount of power consumed by the first camera or the camera circuitry coupled to the first camera in the second operation mode is different than an amount of power consumed by the first camera or the camera circuitry in the first operation mode.
