Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Aspects of the present disclosure relate to systems and methods for placing a camera into a low power mode. An example device may include a memory and a processor. The processor is configured to determine that the first camera is to be placed into a low power mode. The first camera is in an active mode and has a first frame capture rate. The processor further is configured to generate and output a command for placing the first camera into the low power mode. Execution of the command causes the first camera to increase the first frame capture rate to a second frame capture rate and go into the low power mode from the active mode after increasing the first frame capture rate to the second frame capture rate.

Abstract: 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.

Abstract: 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.
