摘要： A system for video synchronization between multiple video streams and methods for making and using same. The video synchronization system can synchronize video frames of a search frame sequence with respect to a reference frame sequence, ordering frames of the search frame sequence so that image data of the search frame sequence corresponds to image data of the reference frame sequence. Video synchronization can be performed for video streams that originate from a single imaging device or multiple imaging devices. Comparison of the search frame sequence to the reference sequence can be performed using point sequences in the image data. The points of the point sequences can be individual pixels or features having one or more pixels. Video synchronization can be performed by maximizing a correlation, between corresponding image data. The systems and methods are advantageously suitable for synchronizing videos taken from mobile platforms such as unmanned aerial vehicles.

摘要： A system for high dynamic range (HDR) imaging and methods for making and using same is disclosed. An HDR module in a camera initializes a set of lookup tables (LUTs) in YUV color space based on exposure configurations of a set of images taken as HDR imaging. The HDR module calculates weights of luminance Y components of the set of images in YUV color space. Based on the calculated weights, the HDR module blends the Y component of the set of images to generate blended Y components. The HDR module combines the blended Y components with corresponding UV components to generate a single image in YUV space. Thereby, the HDR module advantageously combines a set of images into a blended HDR image with only blending the Y component of the set of images.

摘要： Systems, methods and/or devices are used to adjust an optical path length. An image sensor (506) is coupled to a camera body (802). A movable coupling of a first optical device (806) to the camera body (802) includes a first coupling position of the first optical device (806) relative to the camera body (802) in which the first optical device (806) is located at a position that intersects a path (826) between the image sensor (506) and a camera body opening (814), and a second coupling position of the first optical device (806) relative to the camera body (802) in which the first optical device (806) is located at a position that does not intersect the path (826) between the image sensor (506) and the camera body opening (814). In other systems, methods and/or devices, a first optical device (1102) is movable relative to the image sensor (506). An optical path length between the image sensor (506) and a camera body opening (814) is continuously adjusted by movement of the first optical device (1102) relative to the image sensor (506). In other systems, methods and/or devices, a first optical device (806) is movably coupled to the camera body (802). When the first optical device (806) is at a first position, a first optical path length occurs between the image sensor (506) and a camera body opening (814). Moving the first optical device (806) to a second position produces a second optical path length, different from the first optical path length, between the image sensor (506) and the camera body opening (814).

摘要： A system for processing a video and methods for making and using the same. The system can obtain a prediction table for a reference frame of the video and code one or more target frames of the video based on the prediction table. The prediction table can be a Huffman table of a difference value for each reference pixel of the reference frame. The difference value is determined based on an actual value of the reference pixel and a prediction value that can be determined based on respective pixel values of one or more pixels adjacent to the reference pixel. The target frames can be coded based on the Huffman table of the reference frame and prediction values of the target frames. The system advantageously does not need to save a whole frame during a course of encoding and, therefore, can save valuable memory space for video processing.
