Abstract: A method of image processing includes obtaining depth information respectively corresponding to one or more objects in an image frame captured by an imaging system based on spatial configuration of the imaging system, calculating one or more rendering parameters associated with one of the one or more objects in the image frame based on at least the depth information of the one or more objects, and rendering the image frame using the one or more rendering parameters to obtain a processed image frame. The processed image frame includes an in-focus region and an out-of-focus region relative to the one of the one or more objects.

Abstract: A system for processing a video obtains a prediction table for a reference frame of the video and codes one or more target frames of the video based on the prediction table. The prediction table is a Huffman table of difference values for reference pixels of the reference frame. The difference value for a reference pixel is determined based on an actual value of the reference pixel and a prediction value determined based on respective pixel values of one or more pixels adjacent to the reference pixel. The one or more target frames are coded based on the Huffman table of the reference frame and prediction values of the one or more target frames.

Abstract: A system for adjusting an optical path length includes a camera body having a camera body opening, an image sensor coupled to the camera body, and an optical device movably coupled to the camera body. The movable coupling of the optical device to the camera body includes a first coupling position of the optical device relative to the camera body and a second coupling position of the optical device relative to the camera body. In the first coupling position, the optical device is located at a position that intersects a path between the image sensor and the camera body opening. In the second coupling position of the optical device, the optical device is located at a position that does not intersect the path between the image sensor and the camera body opening.

Abstract: A system for image demosaicing and methods for manufacturing and using same. The image demosaicing system includes a lens, a mosaicing filter, an image sensor array and a processing module. The processing module is configured to perform adaptive demosaicing on a mosaiced image that was generated from sensed light that passed through the lens and mosaicing filter. The method of image demosaicing comprises interpolating values of unknown red, green and blue pixels in a horizontal and vertical direction and adaptively selecting one of the interpolation results for each pixel. The disclosed system and method provide for high quality image processing while operating at various Signal to Noise Ratios (SNRs) and require minimal computational time and overhead.

Abstract: System and method can support three-dimensional display. The system can receive a plurality of image frames, which are captured by an imaging device on a movable object. Furthermore, the system can obtain state information of the imaging device on the movable object, and use the state information to configure a pair of image frames based on the plurality of image frames for supporting a three-dimensional first person view (FPV). Additionally, an image frame selected from the plurality of image frames can be used for a first image frame in the pair of image frames.

Abstract: A UAV is provided to cancel background noise from audio data collected by the UAV. The UAV is provided with one or more background microphones in a proximity of one or more background noise-producing components. The UAV is also provided with one or more audio source collecting microphones. The audio data collected by the background microphones may be used to reduce or cancel interfering background noise from the audio signal detected by the audio source collecting microphone. The target audio may be captured or recorded with little or no background noise.
