    摘要: An amount-of-movement detection device which is capable of detecting the amount of movement with a high degree of accuracy when the amount of movement of an image is detected by hierarchical block matching method. An amount-of-movement detection device 1 forms image data S2.sub.n and S3.sub.n of plural hierarchies having different resolutions from each other, by input image S1.sub.n input at a first point in time, and forms multiplexed image data S2.sub.n-1 and S3.sub.n-1 of a higher hierarchy of low resolution, based on an input image S1.sub.n-1 input at a second point in time, by selecting pixels overlapping with each other from the image data of the lower hierarchy having higher resolution and reducing them in size, in order to detect a motion vector by block matching at a predetermined block unit for each of the hierarchies corresponding to the hierarchized image data S2.sub.n and S3.sub.n and the multiplexed and hierarchized image data S2.sub.n-1 and S3.sub.n-1. Thus, the accuracy in the detection of an amount of movement can be greatly enhanced.

    摘要: An information processing device, which includes: a data holding section which holds first time-series data of an operation parameter which varies through a predetermined capturing operation; a data comparing section which compares second time-series data of the operation parameter with the first time-series data, the second time-series data being correlated with a moving image recorded through an actual capturing operation and varying through the actual capturing operation; and a data area specifying section which specifies, among the second time-series data, a data area corresponding to the first time-series data on the basis of the comparison of the first and second time-series data.

    摘要: There are disclosed methods and systems (and related data structures) for processing metadata in files, including media files, so that an alteration or falsification of the metadata can be detected. According to certain embodiments, the metadata includes hash values and digital signatures that were generated by a content server. These hash values and digital signatures can be used by a client device to authenticate the metadata.

Sequence pages 121A, 121B, formed respectively with respect to all of directories 122A, 122B, on a disk and the ICVs formed on the basis of the D-ICVs stored in all of the sequence pages 121A, 121B, . . . are stored into a sequence block 114. Since the MAC values are closed and managed every directory by the sequence pages 121A, 121B, . . . , a data alteration check can be executed every directory. An alteration check of data recorded on a recording medium can be efficiently performed.
