A first image taken by a first camera device in the plurality of camera devices and first imaging environment information indicating a first imaging environment of the first camera device at a time of taking the first image is acquired. By using a parameter table that manages imaging environment information indicating an imaging environment at a time of taking an image previously by a camera device and a recognition control parameter indicating a detector corresponding to an imaging environment, a first recognition control parameter indicating a first detector corresponding to third imaging environment that is identical or similar to the first imaging environment indicated by the first imaging environment information acquired from the first camera device is selected from the recognition control parameters. The first image acquired from the first camera device is recognized by using the first detector indicated by the selected first recognition control parameter.

A management device performs a first determination to determine whether an imaging device can include an imaging area needed by any one of one or more existing applications, and an imaging area needed by a newly operated application in an imaging range determined by a zoom magnification, and if result of the first determination is affirmative, generate information indicating that the newly operated application can be installed in the imaging device.

Management device, imaging device, imaging system, and determination method

An image distribution apparatus that ensures both privacy protection and security is provided. A private area storage section stores private areas relating to the privacy of users. A cutout area storage section stores, as a cutout area, an area requested by an identified user to be distributed. An image processing level storage section stores an image processing rule that defines an image processing level for each of areas having different levels of privacy. An image processing area generation section acquires the cutout area of the identified user from the cutout area storage section, acquires, from the private area storage section, a private area of the identified user and a private area of a person other than the identified user, which private areas are contained in an image of the acquired cutout area, acquires the image processing rule from the image processing level storage section, and then determines an image processing method for each area in the cutout area in accordance with the acquired image processing rule.

Image distribution apparatus

A data processor comprises a decoder for decoding the compressed data into decoded data while reading the compressed data from a first data storage, a second data storage for storing therein the decoded data, a DA converter for converting the decoded data into an analog signal while reading the decoded data in real-time, a first controller for controlling the decoder to perform intermittent operation by executing a process between reading the compressed data and storing the decoded data at a speed faster than real-time, a clock/power controller for making a restriction of power consumption of the decoder and the first controller in downtime of the intermittent operation, a second controller for outputting a control signal in accordance with the storage state of the decoded data, and an activation controller for controlling the clock/power controller to lift the restriction in response to reception of the control signal.

Clock and power control for intermittent operation of decoder

A data transmission apparatus for sequentially transmitting data in units of packets each containing transmission data to the receiving end, comprises: a reception unit for receiving the transmission data as an input signal; a packet formation unit for receiving the transmission data received, and forming an uncompressed packet in which predetermined transmission data is stored as uncompressed data, and a compressed packet in which at least a portion of transmission data that follows the predetermined transmission data is compressed and stored as compressed data; a reference information management unit for holding and managing, as reference information, information relating to the uncompressed packet formed by the packet formation unit; and a transmission unit for transmitting the respective packets formed by the packet formation unit, as a transmission signal, to the receiving end. The packet formation unit forms compressed data to be stored in a compressed packet, on the basis of the transmission data of the uncompressed packet and the reference information stored in the reference information management unit. Therefore, the number of packets to be discarded at the receiving end due to an error which has occurred in the radio section is reduced, whereby the quality of data transmitted in the transmission path including the radio section is improved.

Data transmission method, data transmission apparatus, data reception apparatus, and packet data structure

A stream data recording device is provided for recording stream data on a recording medium. The stream data recording device includes a stream reception/analysis unit (), acquiring stream data from reception data, a a missing portion detection unit () detecting a missing packet portion in the acquired stream data, a section information generation unit () generating time information specifying the duration of the unreceivable section including the packets whose missing portion has been detected and position information specifying the position of the unreceivable section in the stream data, and a recording unit () recording the acquired stream data, the generated time information and position information on the recording medium. Thus, even if the recording-target stream data is missing a portion during reception of the stream data, the data can be correctly played back from the seek time specified by a user.

The apparatus including a reception unit receiving the transmission data as an input signal, a packet formation unit receiving the transmission data, and forming an uncompressed packet in which predetermined transmission data is stored as uncompressed data, and a compressed packet in which at least a portion of transmission data that follows the predetermined transmission data is compressed and stored as compressed data. The apparatus also including a reference information management unit holding and managing as reference information related to the uncompressed packet, and a transmission unit transmitting the packets formed by the packet formation unit. The packet formation unit forming compressed data to be stored in a compressed packet, based on the transmission data of the uncompressed packet and the reference information.

It is an object of the present invention to provide a contents reproducing device which can perform an intermittent operation with improved responsiveness to user request. The contents reproducing device according to the present invention includes: an input operation unit (), a system state managing unit (), a system information storing unit (), a contents reproduction control unit (A) (), a state after next candidate extracting unit (), a contents reproduction control determining unit (), and a contents reproducing unit (). The contents reproduction control determining unit () determines whether or not a candidate related to the contents reproduction control is in the state after next candidates extracted by the state after next candidate extracting unit (). Therefore, the contents reproducing device according to the present invention can improve responsiveness to the user request by shortening the cycle of the intermittent operation of the contents reproducing unit () when it is determined that there is a possibility that a user request related to the contents reproduction control is inputted, and by lengthening the cycle of the intermittent operation of the contents reproducing unit () when it is determined that there is no possibility that a user request related to the contents reproduction control is inputted.

A packet compressoroperates under a reliable mode or an optimistic mode. A mode determination unitcounts the number of ACK packets or NACK packets received by a unit time X by an ACK/NACK packet receiver. When the counted number of NACK packets is larger than a predetermined value Y, the mode determination unitswitches the operation mode of the packet compressorto the reliable mode. When the counted number of ACK packets is larger than a predetermined value Z, the mode determination unitswitches the operation mode of the packet compressorto the optimistic mode.
