Systems and techniques are provided for camera synchronization. An example method can include determining, for each camera of a plurality of cameras, a common point within an exposure time corresponding to a frame being requested from each camera. The method can include determining, based on the common point determined for each camera of the plurality of cameras, a respective synchronization error of each camera from the plurality of cameras. The method can include adjusting, based on the respective synchronization error, a duration of the frame at one or more cameras from the plurality of cameras, wherein the adjusted duration of the frame aligns the common point within the exposure time at each camera for the frame.

Systems and techniques for camera synchronization

Examples are described of marking specified regions of stored image frame buffer data in an image frame buffer. An imaging system can read the specified regions of the image frame buffer to identify whether the marking has been overwritten or not. The imaging system can thus efficiently identify how much of the image frame buffer has been overwritten with data from a new image frame. Based on this, the imaging system can retrieve partial image frame data from the image frame buffer and can process the partial image frame data, for instance to composite the partial image frame data with virtual content and/or to perform distortion compensation. The processed partial image frame data can be uploaded to a display buffer and displayed by a display, either as-is or once more of the frame is captured and processed. The imaging system can also perform auto-exposure using the partial image frame data.

Low latency frame delivery

Image processing can include storing a first image and a second image in response to a first command. The first image can be captured by a first camera and comprise first pixels and have a first field of view. The second image can be captured by a second camera and comprise second pixels and have a second field of view. A second command can be received and the first image can be edited based on the second command. The edited image can have a third field of view and comprise pixels based on the first pixels and the second pixels.

Multi-camera post-capture image processing

Aspects of the present disclosure relate to systems and methods for assisting in positioning a camera at different zoom levels. An example device may include a memory configured to store image data. The example device may further include a processor in communication with the memory, the processor being configured to process a first image stream associated with a scene, independently process a second image stream associated with a spatial portion of the scene wherein the second image stream is different from the first image stream, output the processed first image stream, and output during output of the processed first image stream a visual indication that indicates the spatial portion associated with the second image stream.

Assist for orienting a camera at different zoom levels

Image processing can include storing a first image of a scene captured by a first camera, storing a second image of the scene captured by a second camera, and storing a first user-composed image. The first user-composed image can be derived from at least one of: (a) the first image and (b) the second image. The image processing can further include: receiving a second command to edit the first user-composed image, editing the first user-composed image, and saving the edited first user-composed image as a second user-composed image.

Producing stabilized video can include: (a) accessing a first video including a sequence of first frames, (b) accessing a second video including a sequence of second frames, and (c) building the stabilized video based on the accessed first and second videos. The stabilized video can include a sequence of stabilized frames. At least one stabilized frame can include pixels derived from at least one of the first frames and at least one of the second frames.

Multi-source video stabilization

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.

Adjustment for cameras for low power mode operation

Methods, devices, and systems for determining one or more image capture settings are disclosed. In some aspects a device includes a processor coupled to a first camera and a second camera. In one aspect, the device may include the first camera and the second camera. The processor is configured to cause the first camera to capture a first image frame and cause the second camera to capture a second image frame. The second image frame being captured at a point in time after the first image frame is captured. The processor is also configured to determine an image capture setting for the first camera based on the second image frame.

Image capture setting determination in devices having access to multiple cameras

Methods, devices, and systems for determining one or more image capture settings for use in flash photography are disclosed. In some aspects a device includes a memory and a processor that is coupled to a first camera, a second camera, a flash unit, and the memory. The processor can be configured to cause the flash unit to emit a flash during a flash operation having a first portion and a second portion. The processor can be further configured to cause the first camera to receive a plurality of image frames during the first portion, determine at least one image capture setting based on at least one of the plurality of frames received by the first camera, and cause the second camera to capture one or more image frames during the second portion based on the determined image capture setting.
