Abstract: Techniques for managing logical camera devices are provided. A system for managing logical camera devices may instantiate logical camera devices having different responsibilities. A first logical camera device may receive and pass image data and metadata to a first application that may perform operations using both the image data and the metadata. A second logical camera device may receive and pass the metadata without the image data to a second application that may perform operations using the metadata but not the image data, thereby preserving power, memory, and/or processor resources that may have unnecessarily been used to provide the image data (e.g., via a buffer stream) to the second application, which may have deleted the image data upon receiving it. Another logical camera device may be instantiated to control other logical camera devices.

Abstract: Techniques for classes of tables for use in image compression are described. Classes of tables for use in image compression may provide increased compression without a reduction in quality compared to conventional image compression techniques. In at least some implementations, a plurality of table classes are generated that correspond to a particular camera subsystem, each table class containing a Huffman table and a quantization table. When an image captured by the particular camera subsystem is encoded, a table class is selected based on camera subsystem parameters associated with the image, and the Huffman table and the quantization table of the selected table class are utilized to encode the image.

Abstract: A method, a system, and computer program product for correcting image artifacts in image data captured by a camera sensor in conjunction with a flash. The method includes extracting, from a buffer, an image data captured by at least one camera sensor. The method then includes determining, from a metadata of the image data, a face in the image data and a position of a first eye and a second eye. The method then includes selecting at least one region of interest around at least one of the first and the second eye based on a size of the face and a distance between the eyes. In response to selecting the at least one region of interest, at least one correction is applied to the at least one region of interest to reduce or eliminate the appearance of at least one image artifact in the image data.

Abstract: A mooring system that uses combination traction winch/windlass units is improved by adding an additional fairlead at each combination unit location and by increasing the strength of existing combination units, their foundations and the foundations of associated equipment such as fairleads and turning sheaves. By these relatively simple upgrades, the mooring capabilities of the system can be economically augmented in those situations where additional lines are desired, such as in areas subject to tropical revolving storms. Normal mooring, when there is no threat of hurricanes, has the anchor and chain attached to the floating structure by wire deployed from the traction winch. When storm season threatens, additional anchors attached to chain run over the windlass can be added, allowing the number of lines to be doubled. The additional anchors can be installed if the floating structure is conventionally moored or if it is attached to pre-set moorings.
