Patent Application Titled "Systems and Methods for Improving Overall Quality of Three-Dimensional Content by Altering Parallax Budget Or Compensating for Moving Objects" Published Online By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C. , by VerticalNews journalists, a patent application by the inventors McNamer, Michael ( Apex, NC ); Markas, Tassos ( Chapel Hill, NC ); Searles, Daniel ( Durham, NC ), filed on April 17, 2013 , was made available online on January 16, 2014 . No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: "A stereoscopic or 3D image consists of a pair of left and a right image that present two different views of an object or a scene. When each one of those images is presented to the corresponding human eye using a suitable display device, our brain forms a three-dimensional (3D) illusion and this is the way we can see the object or scene in three dimensions. A stereoscopic image pair can be created by utilizing two sensors with a slightly different offset that take a picture of a subject or a scene simultaneously, or by using a single sensor and take two pictures side-by-side but at different times. There are several 3D-enabled cameras in the market today that are basically 2D cameras with software that guide users how to take two pictures side-by-side and create a 3D pair. Also, 3D content can be created using standard camera with no hardware or software modifications by again taking two pictures side-by-side. Methods for creating 3D images using two pictures taken side-by-side can be found in U.S. patent application publication numbers 2010/043022 and 2010/043023. Although, such products present great value to the consumers since they can use existing camera platforms to create 3D content, a problem is that since the two pictures are taken at different timeframes, there is a possibility that objects in the scene may move between the times the two different pictures were captured. Typical problems arising from this 3D capturing method may include moving people, animals, and vehicles, reflections, as well as leaves of trees and water during windy conditions. This will result in a 3D image that is very difficult to see and can cause strain and eye fatigue. In addition, during this two-picture shooting technique, it is possible that the created 3D image will not have the correct parameters which will also result into a non-optimal composition and may also cause eye fatigue. For at least these reasons, systems and methods are needed for providing improved overall quality of 3D content." In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "The subject matter disclosed herein provides editing methods applied to 3D content to eliminate improper attributes that may cause viewing discomfort and to improve their overall quality. Editing methods disclosed herein provide detection and compensation for moving objects between the left and right images of a stereoscopic pair. In addition, methods disclosed herein can adjust various image characteristics, such as parallax budget, to create a stereoscopic pair that is more comfortable to view based on user preferences. "The presently disclosed subject matter can provide a comprehensive methodology that allows for both fully manual compensation, manually-assisted auto compensation, and fully automatic. In addition, the present disclosure can be applied to various methods of capturing images to create a stereoscopic image. "According to an aspect, moving object compensation between the two images can be identified by either using visual or automated means. A user looking at a 3D image can recognize areas of discomfort and can identify specific locations that need to be corrected. In addition, feedback can be provided to the user where such problem areas exist in an automated way. Once such problems have been identified, compensation can be achieved by copying an appropriate set of pixels from one image to the other image (i.e., target image) or vice versa. During the copying process, pixels belonging to the moving object need to be copied at the proper location to accommodate for the proper depth of the moving object. The identification of the proper location can be completed using manual assisted process or a fully automated one. The same process can repeat for all moving objects in a scene to create a 3D image with optimized viewing experience. Once the moving object compensation process has been completed, images can be adjusted to optimize for color, exposure, and white-balancing. Also, other 3D parameters can be adjusted to optimize for 3D experience. Those parameters include the perceived distance of the closest and the furthest objects in the image, as well as the total parallax budget. Finally, a 3D image can be cropped and the order of left and right images can be reversed to accommodate for different display characteristics.
