    Abstract: Video clips and images captured by one device (e.g., a camera) are associated with one or more synchronization labels such as synchronization device labels and synchronization time labels determined by the device. Synchronization device labels can be used to identify devices that are synchronized. Synchronization time labels indicate relative timing between the devices that are synchronized. When a device is on, it transmits a synchronization signal and receives another synchronization signal transmitted by another device in response to receiving the synchronization signal it has transmitted. The two devices each calculate a synchronization device label and a synchronization time label using the synchronization signals and associate the synchronization device label and synchronization time label with video frames and images captured. Video clips and images can subsequently be aligned using the associated synchronization device labels and the synchronization time labels.

    Abstract: A system and a process configuration generates a unitary rendered image for a video from at least two cameras. The configuration detects a communication coupling of at least two cameras and determines a master camera and a slave camera. The configuration determines an orientation of camera sensor of the master camera and the slave camera and determines a first frame of a video for a synchronization point for a start of a video capture. The configuration captures and reads images from the master camera sensor and the slave camera sensor in response to the start of the video capture and orientation of the camera sensors.

    Abstract: In a video capture system, a virtual lens is simulated when applying a crop or zoom effect to an input video. An input video frame is received from the input video that has a first field of view and an input lens distortion caused by a lens used to capture the input video frame. A selection of a sub-frame representing a portion of the input video frame is obtained that has a second field of view smaller than the first field of view. The sub-frame is processed to remap the input lens distortion to a desired lens distortion in the sub-frame. The processed sub-frame is the outputted.

    Abstract: An image sensor compresses image data prior to transmitting the image data to a DSP. The image sensor captures light representing an image, for instance via a camera's aperture. A focal plane array converts the captured light into pixel data. The pixel data is sorted into categories, and is compressed in parallel by a compression engine. The compressed pixel data is then sent to a DSP, which may be located off-chip. The DSP then decompresses the compressed pixel data, performs image signal processing operations on the compressed pixel data, and then compresses the processed pixel data into a digital image format. The image sensor may buffer the pixel data for one or more images to accommodate for slowdown by the compression engine. The pixel data may be sorted by row and column of a pixel array. Alternatively, the pixel data may be sorted by color from a Bayer color filter.
