A shared area in which a three-dimensional image presented by a three-dimensional display is to be arranged in order to be observed from any position in the viewing area is created based on the acquired information. Based on the acquired information, a specific area in which a three-dimensional image presented by the three-dimensional display is to be arranged in order to be observed from a specific position in the viewing area is created. The data indicating the created shared area and the data indicating the specific area are generated.

Abstract: A detection unit successively selects each of a plurality of blocks of a target image as a target block and detects a motion vector of the target block using a reference image. During motion vector detection, a control unit performs control to partially store the reference image into a storage unit so as to achieve a state where a search range for the target block is stored. The detection unit selects each of the plurality of blocks as the target block in an order of raster scan for each of N regions obtained by dividing the target image in a horizontal direction. When a temporal distance between the target image and the reference image is a second distance that is longer than a first distance, a value of N is large compared to a case where the temporal distance is the first distance.

Abstract: There is disclosed herein examples of systems and methods for compressing a signal. Samples of the signal can be segmented and the samples within each of the segments can be averaged to produce a value that can represent the samples within the segment. The number of samples to average in each segment may be determined based on an error threshold, such that the number of samples being averaged can be maximized to produce less data to be transmitted while maintaining the representation of the samples within the error threshold. In some embodiments, a signal can be separated into a timing reference, a representative periodic function, and a highly compressible error signal. The error signal can be utilized for reproducing a representation of the signal.

Abstract: A 3D imaging and image processing system is configured to collect and analyze data defining a predetermined set of physical and visual attributes of a collectible object. The collected 3D image information is stored in a database, which also contains a record of 3D image information associated with a defined gold-standard object of the same kind. The analysis is used to generate as an output an “objective valuation” of the collectible object based upon a comparison to the stored gold-standard image data. When used with collectible coins, the objective valuation is used in the assignment of a specific “grade”, using a well-known industry grading standard.
