A recording apparatus has: a stream generating unit for generating a first stream constituted of a first moving image signal at a first frame rate and an input audio signal and a second stream constituted of a second moving image signal at a second frame rate faster than the first frame rate and a predetermined audio signal; a recording unit for recording the first and second streams; and an instructing unit for instructing a change-over of a frame rate, wherein in accordance with an instruction output from the instructing unit during recording the first stream, the stream generating unit outputs the second stream instead of the first stream, and the recording unit records the second stream output in response to the instruction by the instructing unit, instead of the first stream.

Recording apparatus

The present invention controls to read encrypted digital data from a detachable storage medium, in which the digital data and a decode key for decoding encryption of the digital data are stored. In reading the digital data, the decode key is read, the decode key is deleted from the storage medium, the encrypted digital data is read, and then encryption of the encrypted digital data is decoded by the read decode key.

Storage medium access control method

A memory management device which is capable of allocating a memory unit accessible at a higher speed to data which is stored in a storage device having memory units different in access speed, without being limited in an storage area. The storage device comprises a BLC flash memory accessible at a predetermined access speed, an MLC flash memory accessible at a lower access speed than the predetermined access speed, a controller, and a RAM. The controller manages the BLC flash memory and the BLC flash memory in units each formed by a plurality of physical pages, and writes data in the physical pages, and the RAM holds page allocation information in which logical pages designated when writing data and the physical pages are associated with each other.

Storage device, system, and method that determines a physical address of a memory unit allocated to a logical address or allocates a logical address to a physical address of a memory unit, based on access speed information of the logical address

A recording apparatus includes a recording unit configured to record moving image data including a plurality of frames on a recording medium. The recording medium includes a plurality of clusters. The apparatus also includes an editing unit of the moving image data, a setting unit configured to optionally set the editing unit, a management information processing unit configured to generate management information including link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters having the moving image data recorded thereon, and a control unit configured to control the recording unit to record a front frame of each editing unit in the moving image data on an area beginning with a cluster of the recording medium based on the editing unit set by the setting unit.

Recording apparatus for recording data to recording medium with a Plurality of clusters

When printing an image on a printing sheet, it is judged whether or not an RFID tag has been arranged in the printing sheet. When an RFID tag has been arranged, an image indicating the presence of RFID tag is printed, or an RFID tag cutting assistant line or the like for invalidating RFID tag is printed, whereby the user can easily recognize the presence of RFID tag. Also, the user can easily cut out and invalidate the RFID tag. When the user's information has been recorded on the RFID tag, a mark indicating the writing of information into RFID tag is attached to the printing sheet, whereby the user can easily recognize the presence/absence of information recorded on RFID tag. Consequently, there can be provided a method capable of identifying and easily discarding a printing sheet with RFID tag which can leak out the user's secret, privacy information or the like, and a method for easily judging whether or not ID information has already been recorded on a printing sheet with RFID tag.

Image forming apparatus and control method thereof

A data recording system and method are provided which, when the removal of a recording medium is detected during data writing, the data recording system retains accessed processing not executed in the data writing, and executes the retained access processing when the removed recording medium is inserted again into the data system.

Data recording system and data access method

A storage managing system and method, the system and method including matching a boundary of a cluster, which is a minimum data unit of a data region of a storage medium having a write protect function, with a boundary of at least one or more consecutive blocks each having a predetermined size, and applying write protection to data in units of the block.

Storage managing system, storage managing apparatus, and storage managing method

This invention provides a technique that deletes data at high speed, and prevents discontinuous cluster chains from being produced due to data deletion. To accomplish this, when data included in the data file is partially deleted from the head of the data file, the location of header information is moved for respective clusters, and the size of the header information is changed, so as to start head data after data deletion from the location immediately after the moved header information.

Data processing apparatus, data processing method, and data processing program

An image processing apparatus, an image processing method, and a program for implementing the image processing method have a capability of recording/playing back a digital image, and the capability can be extended without a significant increase in load imposed on software. On the basis of camera information and picture-taking information, a XML generator produces a XML file to be written in a maker note area. The XML file is input to a maker note generator to produce maker note data including maker note IFD tags. The maker note is input together with the picture-taking information and the camera information to an Exif IFD generator to produce Exif IFD data. Finally, the Exif IFD data and compressed image data are input to an Exif generator to produce a Exif file. In this manner, the Exif file including the maker note area in which image attribute information is described in the XML language is produced.

Image processing apparatus and method for describing recorded attribute information using tags, and program for implementing the method

This invention has as its object to provide an apparatus which can match the brightness of an image displayed on a viewfinder with a target luminance level in actual exposure. To achieve this object, the apparatus has an image sensing sensor for converting an optical image into an image signal, a viewfinder for displaying the image signal obtained by the image sensing sensor, and a correction device for correcting the brightness of the viewfinder in accordance with the difference between the luminance level of the image signal obtained by the image sensing sensor, and a target luminance level.

Image sensing apparatus executing exposure control using object luminance information

Radio equipment based on an AFC system comprising a local oscillator, a reference frequency oscillator, a receiver, a frequency comparator, an AFC controller, a temperature detection sensor, and a memory. The AFC controller inputting, when starting AFC, reads out a control frequency corresponding to the detected temperature inputted thereinto to control the reference frequency for the reference frequency oscillator. When a lock signal is inputted thereinto, the detected temperature and control frequency are stored in a memory.
