Abstract:
A system monitoring unit uses an external debugging unit to monitor the state of an internal CPU when a control program stored in a memory of a target system controls an internal CPU of the system to operate via an internal bus of the system. The system monitoring unit includes an internal-bus-address comparing circuit for detecting, in real time, based on information on the internal bus, information on the accessing of the internal bus by the internal CPU. By outputting the information on the accessing of the internal bus by the internal CPU to the debugging unit, the system monitoring unit can output the state of the internal bus while controlling the internal CPU to operate.

Abstract:
PROBLEM TO BE SOLVED: To provide an information processor and an information processing method for achieving data recording processing to minimize the recording error of file system information or the like. SOLUTION: The information processor has two modes as information writing modes for an information recording medium, that is, a normal writing mode (a) for not executing the priority recording processing of the file system information and an immediate writing mode (b) for executing the priority recording processing of the file system information. The information processor selects the write mode according to preset conditions, and executes the sequential recording processing of the file system information. On the basis of, for example, at least either the count value of a data recording instruction frequency from the start of the normal writing mode or the value of a timer which measures an elapsed time from the start of the normal writing mode, the information processor executes a mode change and the sequential recording processing of the file system.

Abstract:
PROBLEM TO BE SOLVED: To provide a recording/reproducing apparatus capable of grasping video data recorded on a record medium quickly and correctly. SOLUTION: When motion picture data are recorded on a record medium 44, an index creator 26 creates a scene index including at least a start position and an end position at a recording space on a record medium for the recorded motion picture data and a representative image data. A memory card 29 stores the created scene index. An index corrector 32 determines whether there is an index to be corrected by overwriting of the motion picture data, based on a plurality of indexes stored at the memory card 29. If the index corrector 32 determines that there is an index to be corrected, it corrects data contained in the index. The apparatus and the method are applicable to a recording/reproducing apparatus for recording data on a tape media and reproducing data currently recorded on the tape media.

Abstract:
PROBLEM TO BE SOLVED: To accurately and quickly discriminate kinds of various streams. SOLUTION: A dummy packet detection and count section 20 of a 1394 interface IC counts number of dummy packets in one frame among isochronous packets included in a stream in the case of communicating the isochronous packets in compliance with the IEEE 1394. A microcomputer 3 discriminates whether 'presence of data stream' or 'absence of data stream' on the basis of the count of the dummy packet and when the 'absence of data stream' is discriminated, a mute control signal denoting mute-on is sent to a signal processing system IC 4.
Abstract:
PROBLEM TO BE SOLVED: To provide an image recording apparatus, an image recording method and a program by which files recorded in a storage medium can be managed finely so as to be familiar for a user. SOLUTION: One image picked up at a time point of still picture imaging operation is recorded on a recording medium as a still picture file, and a plurality of images picked up from a time point of motion picture imaging starting operation to a time point of motion picture imaging ending operation are recorded on the recording medium as a motion picture file. Each time these files are recorded on the recording medium, an identifier of the relevant file is entered to an image management file in the order of imaging for each date.

Abstract:
PROBLEM TO BE SOLVED: To correctly access a recording medium based on a free capacity when the free capacity of the recording medium is recorded in a separate nonvolatile memory, for example, in application to a digital still camera, regarding a recorder, a method for managing the recording medium, a program of the method, and the recording medium recording the program. SOLUTION: The free capacity of the recording medium is recorded in a separate nonvolatile memory and, in starting, the recording of this free capacity is checked based on the total capacity of the recording medium to start recording.

Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and a method in which drop determination processing of a device can be performed accurately. SOLUTION: First decision deciding whether the apparatus becomes an agravic state or not is performed as determination processing in which the apparatus is dropped or not, and second decision deciding whether the apparatus is a free fall state or not is performed using acceleration history information already stored in a storage part. In the second decision processing, it is identified whether large force is applied in the past or not based on history information, also drop determination processing based on speed becoming the agravic state is performed, and a state in which a user raises the apparatus and brings down is discriminated. By this constitution, for example, in a device mounting a HDD, such needless processing can be prevented that a head is rettreated at the time of non-drop. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To easily search an image acquired from a desired acquisition source when acquiring an image from an external device. SOLUTION: An acquisition section 71 acquires image data form a memory card 43 or the external device 51. An image management section 73 controls the record by a record control section 74 to manage the acquired image data associated with acquisition source information indicating that the image data are acquired from the outside. This invention can be applied to, for example, a digital still camera. COPYRIGHT: (C)2007,JPO&INPIT
