A video processing device includes a video obtaining unit configured to obtain video data by capturing video of a specific area, a video accumulating unit configured to accumulate the video data obtained by the video obtaining unit, a data input unit configured to input event occurrence data indicating an event that has occurred in a video image corresponding to the video data obtained by the video obtaining unit and object specifying data for specifying an object relating to the event, and an addition processing unit configured to add the event occurrence data and object specifying data input by the data input unit to the video data accumulated in the video accumulating unit using a predetermined format through provision of link data for linking the video data to the event occurrence data and the object specifying data.

Video processing device, video processing method, and program

A video processing device includes a video accumulating unit configured to accumulate video data obtained by capturing video of a specific area, event occurrence data indicating an event that has occurred in a video image corresponding to the video data, and object specifying data for specifying an object relating to the event, a video processing unit configured to apply a predetermined effect to the video data accumulated in the video accumulating unit in accordance with the event occurrence data and the object specifying data that are added to the video data accumulated in the video accumulating unit to produce a modified video image, and a video output unit configured to output the modified video image to which the effect has been applied by the video processing unit.

A file system that is organized in an operating system to manage a file to be recorded in a recording device in compliance with a file access request from an application. The file system includes a first recording section recording in a recording device a file that includes a management information section and a data section. A second recording section, which, when the first recording section records the file that includes the management information section and the data section, adds, as needed, an extended management information section that records information other than the management information section about the data section.

File system and file information processing method

When the size of a file which has been read out from a magnetic disc unit less than a predetermined value, a CPU the file onto a magnetic tape of a magnetic tape unit as an archive file of a standard form to which attribute information where its size is represented by octal numeral is added. On the other hand, when the size of the file is the predetermined value or more, the CPU records such a file onto the magnetic tape as an archive file of an expanded form to which attribute information where the size of the file is represented by hexadecimal numeral and including identification symbol indicating hexadecimal representation is added. Where the attribute information of the recorded archive file does not include identification symbol, the archive file is reproduced as a standard form. Where the attribute information includes identification symbol, the archive file is reproduced as an expanded form.

Data recording device, data recording method, data reproducing device and data reproducing method

The invention is equipped with setting means for setting whether files under the same custody structure are preferentially selected, procuring means for procuring information on a day on which the last access was made and information on the file size regarding each one of the respective files stored in the memory means, calculating means for calculating a score regarding each of the respective files according to the number of days that have lapsed from the day of the last access and the file size, and selecting means for selecting a desired file from among the respective files by using the score and the result of the setting performed by the setting means. With this construction, when in the computer of hierarchy storage management type collectively replacing a file within the buffer memory with a file that is newly transferred from the main memory, it is so arranged that a plurality of files under the same directory can be collectively replaced.
