(First embodiment)
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following embodiment, a digital video camera as an example of an information recording apparatus capable of recording moving image data as an example of a series of data and relay recording will be described. However, the series of data in the present invention is not limited to moving image data, and the information recording apparatus is not limited to a digital video camera.

  FIG. 1 is a block diagram showing a configuration example of a digital video camera 100 as an example of an information recording apparatus according to the first embodiment of the present invention. The lens unit 201 includes a fixed lens group, a variable power lens group, a stop, and a correction lens group (all not shown). The correction lens group has a function of correcting the imaging position moved by the movement of the variable power lens group and a focus adjustment function. The imaging device 204 is, for example, a CCD (Charge Coupled Device), and converts the subject image formed on the imaging surface by the lens unit 201 into an electrical signal in pixel units to generate an imaging signal. The A / D processing unit 205 performs predetermined processing on the imaging signal and outputs digital image data. The lens unit 201, the image sensor 204, and the A / D processing unit 205 constitute a camera unit 200. Although not shown in FIG. 1, the camera unit 200 includes a variable power lens group included in the lens unit 201, an actuator for driving a diaphragm, a sensor for correcting camera shake (for example, an angular velocity sensor), an optical camera shake. It also has a correction mechanism (shift lens, etc.).

The camera unit control unit 218 controls the operation of each element of the camera unit 200 according to the control of the main control unit 210. For example, information obtained from the camera unit 200 such as in-focus information and camera shake information is transmitted to the main control unit 210. The microphone unit 209 detects environmental sound during imaging. The microphone unit 209 includes an amplifier and a band limiting circuit. The A / D processing unit 219 receives the analog audio signal output from the microphone unit 209 and outputs digital audio data.

  The main control unit 210 is, for example, a microcomputer that controls the entire digital video camera 100. The main control unit 210 includes a non-volatile memory (ROM) for storing programs, a volatile memory (RAM) serving as a work area, an external bus for accessing data to other hardware and accessing a control register, time At least a timer for measuring. The bus 203 is a transmission path for transferring data between connected blocks according to the control of the main control unit 210.

  The encoder unit 202 encodes the digital image data and digital audio data from the A / D processing units 205 and 219 in accordance with, for example, the MPEG (Moving Picture Experts Group) 2 system under the control of the main control unit 210. The encoder unit 202 further multiplexes the encoded data in the MPEG2 format in time series order to generate compressed video data. In addition, the encoder unit 202 has a function of notifying the main control unit 210 of information necessary for conversion between a data position and a frame position, for example.

  The recording circuit unit 221 has interfaces with the encoder unit 202, the memory 206, the memory card A 220, the memory card B 223, and the decoder unit 208, and controls data transfer under the control of the main control unit 210. The memory 206 is a storage area that each block can use for work.

  The function determining unit 301 of the recording circuit unit 221 determines whether or not the memory card A220 and the memory card B223 have a wireless communication function by referring to a memory card ID assigned to each memory card, for example. For example, the function determining unit 301 executes a determining process when the digital video camera 100 is turned on or when a memory card is inserted or removed.

  The wireless control unit 302 controls the wireless communication function in the memory card, specifically, power control of the wireless transmission unit in the memory card and transmission control of moving image data stored in the memory card. The recording medium switching unit 303 switches the recording medium to which the moving image data is recorded. For example, during relay recording in which a series of data is continuously recorded across a plurality of recording media, the recording medium switching unit 303 is set when the remaining recording capacity of the recording medium being recorded falls below a predetermined threshold. The recording medium of the recording destination is switched based on the recording order. The function determining unit 301, the wireless control unit 302, and the recording medium switching unit 303 may be individual hardware, or two or more may be realized by one hardware. Further, the main control unit 210 may perform these functions.

  The digital video camera 100 is provided with a menu for setting validity / invalidity of a wireless communication function of a recording medium having a wireless communication function. When the wireless communication function is set to be valid by a menu operation or the like by the user, the wireless control unit 302 controls power supply to the wireless communication unit in the memory card. In addition, when the wireless communication function is set to be invalid, the wireless control unit 302 performs control so that power supply to the wireless communication unit in the memory card is stopped. This setting is held in the EEPROM 211.

  The memory card A220 and the memory card B223 are examples of recording media that can be used as recording destinations for captured moving images. The recording circuit unit 221 has interfaces with the memory 206, the memory card A 220, the memory card B 223, and the bus 203. Then, the recording circuit unit 221 performs conversion for accessing the control registers of the memory card A 220 and the memory card B 223 from the main control unit 210 and the like.

  In the memory card A 220 and the memory card B 223, moving image data including video captured by the camera unit 200 and audio recorded by the microphone unit 209 is recorded. Note that the memory card A 220 and the memory card B 223 have an interface that can be connected to the recording circuit unit 221 and include a circuit for reading and writing data from and to a semiconductor memory included in the memory card A 220 and the memory card B 223. The recording circuit unit 221 of this embodiment has a so-called direct memory access (DMA) function. Therefore, automatic transfer of data is performed by designating the read start address and data amount of the memory 206 and the write start address of the memory card A 220 and the memory card B 223 to the recording circuit unit 221. The same applies to reading from the recording medium to the memory 206.

  The decoder unit 208 sequentially reads compressed video data and compressed still image data from the address of the memory 206 designated by the main control unit 210. The decoder unit 208 converts the read compressed video data and compressed still image into, for example, ITU-R BT. 656 (CCIR656) or the like is converted into a digital audio signal and a digital audio signal and output. The decoder unit 208 performs a reduction process if necessary when reproducing the compressed still image data.

  The video output unit 217 and the audio output unit 207 respectively convert the digital video signal and the digital audio signal converted by the decoder unit 208 into analog signals for output to an external device. For example, a television receiver or the like is connected to the video output unit 217 and the audio output unit 207.

  The on-screen display (OSD) unit 213 superimposes information such as a menu screen for performing various settings, a title, and time on a digital video signal output from the decoder unit 208 and outputs the superimposed information to the video output unit 217. The OSD unit 213 also has a function of capturing a digital video signal input from the decoder unit 208, performing a reduction process, and superimposing it on an arbitrary position of an image corresponding to the digital video signal.

  The switch operation unit 212 is an input device group for a user to operate the digital video camera 100, and the input device is not limited to a switch. The main control unit 210 determines the content of input given by the user to the switch operation unit 212 and the touch panel 215, and executes an operation corresponding to the input.

  Data is read from and written to the memory card A 220 and the memory card B 223 in accordance with a predetermined file system (data file management structure). The main control unit 210 has software (driver) for performing such data management. The EEPROM 211 is a rewritable ROM, in which, for example, firmware and setting values of the digital video camera 100 are written.

  An EVF (Electronic View Finder) 214 is a display device for confirming the imaging range of the digital video camera 100. The liquid crystal panel 216 is a display device larger than the EVF 214 and is used for displaying a menu screen. Note that the liquid crystal panel 216 can also function as an EVF. The liquid crystal panel 216 is provided with a touch panel 215, and the user can directly operate the GUI displayed on the liquid crystal panel 216 with a finger or the like to input menu operations and various instructions.

  The screen control unit 222 calculates the input position from the touch panel 215 and determines the input content based on the relationship with the image displayed on the liquid crystal panel 216. The screen control unit 222 further performs display control of a virtual button (GUI) displayed on the liquid crystal panel 216.

  Here, the relay recording will be described with reference to FIG. FIG. 2A shows a case where the order of recording media used for relay recording is set in the order of slot 1 (memory card A220) → slot 2 (memory card B223). Recording is started with the memory card A220 as the recording destination, and when the recordable capacity becomes equal to or less than the threshold (for example, if the threshold is 0, the recordable capacity is exhausted), the recording medium as the recording destination is transferred from the memory card A220 to the memory card. Switch to B223 and continue recording.

  When neither the memory card A220 nor the memory card B223 has a wireless communication function, there is no particular problem even if relay recording is performed while changing the recording destination in the order shown in FIG. However, for example, when the memory card B 223 has a wireless communication function, a problem occurs. This problem will be described with reference to FIG. FIG. 2B shows a case where the same relay recording as that in FIG. 2A is performed when the memory card B 223 is a memory card with a wireless communication function. In this case, there is no particular problem with the relay recording itself. However, when the memory card B 223 becomes communicable with the wireless network after at least recording to the memory card B 223 is completed, the memory card B 223 stores the recorded data in a preset transfer destination (such as a user PC or a server on the network). Automatically forward to. That is, only the section recorded on the memory card B 223 in the series of contents recorded in the relay is wirelessly transferred to the server. Conventionally, a method for dealing with such a problem has not been studied at all.

  FIG. 3 shows an example of management information recorded on each memory card when relay recording is performed in the order from the memory card A220 to the memory card B223 in the digital video camera 100 of the present embodiment.

  The content management information 401 is recorded on the memory card A220, and the content management information 402 is recorded on the memory card B223. Items such as the memory card content ID, recording date and time, start position, recording time, and capacity are information relating to data recorded in each memory card. Further, the relay ID is information indicating whether or not the content with the content ID is continuously recorded at the next recording destination. For example, “0” is recorded when the relay recording is not performed (that is, the recording is completed in the memory card A220). When the relay recording is performed, the recording medium and the content ID on which the continuation is recorded are displayed. Contains identifying information. The information specifying the recording medium may be unique information such as a memory card ID, for example. Each time the main control unit 210 records the content data file on the recording medium, the main control unit 210 generates content management information for the content and records the content management file on the recording medium on which the content data file is recorded.

  When relay recording content from the memory card A220 to the memory card B223, the main control unit 210 first sets the memory card ID of the memory card B223, which is the next recording destination, to the relay ID of the content management information 401 of the memory card A220. Record. Next, the main control unit 210 starts recording data relating to the same content in the memory card B 223 and generates content management information 402. Then, the main control unit 210 adds the content ID of the content management information 402 to the relay ID of the content management information 401 of the memory card A220. Thereby, in the relay ID of the content management information 401, the memory card ID of the memory card B223 that is the relay recording destination and the content ID recorded in the memory card B223 are recorded.

Next, a recording operation in the digital video camera 100 of the present embodiment will be described using the flowchart of FIG.
Here, it is assumed that the use order (recording order) of the recording media at the time of relay recording is set in advance. Note that the recording order may be set according to user settings, for example, or the main control unit 210 may automatically set the order when setting the relay recording mode so that relay recording is performed from the one having a large recordable capacity. Note that the user may be able to set what rule the recording order is automatically set for.
Here, it is assumed that the digital video camera 100 is in a recording standby state. In the recording standby state, the camera unit 200 continuously captures images for preview, and the EVF 214 and the liquid crystal panel 216 function as a viewfinder.

  In S501, the main control unit 210 determines whether or not the relay recording mode is set by referring to the EEPROM 211, for example. If the relay recording is not set, the main control unit 210 determines in S515 whether or not the recording start is instructed by the operation of the recording start key included in the switch operation unit 212 or the touch panel 215.

  When detecting the recording start instruction, the main control unit 210 starts the recording process in S516. In the recording process, an image captured by the camera unit 200 is recorded on a recording medium through the encoder unit 202 and the recording circuit unit 221. The recording medium to be recorded here is a preset recording medium (for example, the recording medium on which recording was performed immediately before) of the memory card A220 and the memory card B223.

  When the recording medium at the recording destination has a wireless communication function and the wireless communication function of the recording medium is set to be valid, wireless transmission is permitted. A wireless transmission unit (not shown) included in the recording medium starts wireless transfer of recorded data when communication with a preset wireless communication network (or preset transfer destination device) becomes possible. Note that if the wireless communication function is not enabled, data is not transferred.

  In step S517, the main control unit 210 determines whether the recording end is instructed by a recording end key included in the switch operation unit 212 or an operation on the touch panel 215. When the recording end instruction is detected, the main control unit 210 ends the recording operation of FIG.

  On the other hand, if it is determined in S501 that the relay recording mode is set, the process proceeds to S502. In step S <b> 502, the main control unit 210 determines whether there is a recording medium (memory card A <b> 220 and memory card B <b> 223 in the present embodiment) mounted on the digital video camera 100 that has a wireless communication function. Specifically, the main control unit 210 acquires the result determined by the function determining unit 301 of the recording circuit unit 221. As described above, the function determination unit 301 can determine the presence or absence of the wireless communication function of the memory card by referring to the memory card ID, for example.

  In step S502, the main control unit 210 performs the process in step S505 if none of the recording media (memory card A220 and memory card B223) has the wireless communication function, and performs processing in step S503 if there is a recording medium having the wireless communication function. Proceed to

  In step S503, the main control unit 210 invalidates the wireless transmission unit of the recording medium having a wireless communication function. For example, the main control unit 210 can disable the wireless communication function of the recording medium by turning off the power of the wireless transmission unit of the recording medium having the wireless communication function through the wireless control unit 302. May be used. For example, a method of changing a setting parameter (a flag or a value for setting validity / invalidity of the wireless transmission unit) held by the recording medium to a value that disables the wireless transmission unit through the wireless control unit 302 may be used. Note that this processing is performed even if the wireless communication function is enabled in advance by a user operation.

  In step S504, the main control unit 210 notifies the user that communication using the wireless communication function of the recording medium is not performed. The notification method is not particularly limited. For example, notification by displaying a message on the liquid crystal panel 216 or outputting a voice message from a speaker (not shown) (which may be connected to the decoder unit 208) can be considered. . Further, the user may be requested to confirm the invalidation of the wireless communication function. For example, when there is a confirmation input from the switch operation unit 212, the main control unit 210 advances the process to S505. The main control unit 210 may automatically advance the process to S505 after a predetermined time has elapsed after the notification message is output.

  In step S <b> 505, the main control unit 210 determines whether recording start is instructed by a recording start key included in the switch operation unit 212 or an operation on the touch panel 215.

  When detecting the recording start instruction, the main control unit 210 starts the recording process in S506. Here, the recording medium that is the first recording destination is the recording medium that has the preset recording order as the first recording medium. At the start of the recording process, the main control unit 210 generates content management information (FIG. 3) and writes it in the recording medium (or memory 206).

  In step S507, the main control unit 210 determines whether the recordable capacity (recordable time or free capacity) of the recording medium being recorded is equal to or greater than a predetermined threshold. If the recordable capacity of the recording medium being recorded is equal to or larger than the predetermined threshold, the main control unit 210 determines in step S508 whether recording end is instructed by an operation of the recording end key included in the switch operation unit 212 or the touch panel 215. To do. When the recording end instruction is detected, the main control unit 210 ends the recording operation of FIG. Note that when the recording end instruction is detected in S508, since the relay recording is not actually performed, the main control unit 210 may delete the content management information recorded in S506.

  If the recordable capacity of the recording medium being recorded is less than the predetermined threshold value in S507, the main control unit 210 in S509 uses the recording medium switching unit 303 to set the recording destination to the recording medium in which the next recording order is set. Recording is continued by switching the recording medium. Note that if the recording medium in which the next recording order is set is not loaded, or if the recordable capacity is less than a predetermined threshold, the main control unit 210 performs the recording operation of FIG. Exit. Also in this case, as in the case where the recording end instruction is detected in S508, since the relay recording is not actually performed, the main control unit 210 may delete the content management information recorded in S506.

  In S510, the main control unit 210 determines whether the recordable capacity (recordable time or free capacity) of the recording medium being recorded is greater than or equal to a predetermined threshold value. If the recordable capacity of the recording medium being recorded is equal to or larger than the predetermined threshold, the main control unit 210 determines in step S511 whether the recording end is instructed by the recording end key included in the switch operation unit 212 or the operation of the touch panel 215. To do. When the recording end instruction is detected in S511, the main control unit 210 ends the recording process, and moves the process to S512. If the recordable capacity of the recording medium being recorded is less than the predetermined threshold value in S510, the main control unit 210 ends the recording process and moves the process to S512.

  In step S512, the main control unit 210 performs association processing. The association process is an update process of the content management information 401 and 402 described above with reference to FIG. The recording time, capacity, relay ID, etc. are updated at the end of recording. When the content management information 401, 402 is written in the memory 206, the updated content management information 401 is written in the recording medium. When the association process ends, the main control unit 210 ends the recording operation of FIG.

  As described above, in the present embodiment, when relay recording is performed on a plurality of recording media, the wireless communication function of the recording medium having the wireless communication function is invalidated. Thereby, it is possible to prevent only the portion recorded on the recording medium having the wireless communication function from being transferred in the same content that is relay-recorded.

(Second Embodiment)
Next, the relay recording operation in the information recording apparatus according to the second embodiment of the present invention will be described. Note that the information recording apparatus according to the present embodiment may be the same as that of the first embodiment except for the processing when the first recording medium used for relay recording has a wireless communication function. Therefore, the following description will be made with the digital video camera 100 described in the first embodiment, focusing on differences from the recording operation in the first embodiment.

  A recording operation in the digital video camera 100 of the present embodiment will be described with reference to the flowchart shown in FIG. In FIG. 5, the same steps as those in FIG. 4 are denoted by the same reference numerals.

  If it is determined in S502 that there is a recording medium having a wireless communication function, in S601, the main control unit 210 uses the recording medium that has the wireless communication function as the first recording medium (recording order first) in relay recording. It is determined whether or not. When the recording medium set with the first recording order has a wireless communication function, the main control unit 210 inquires of the user whether or not to perform data communication using the wireless communication function of the recording medium in S602.

  Specifically, the main control unit 210 displays, for example, an inquiry message “Do you want to enable the wireless communication function of the first recording medium for relay recording?” On the liquid crystal panel 216 together with the “Yes” and “No” GUI buttons. Then, the main control unit 210 determines whether a user instruction indicating “Yes” or “No” is input from the touch panel 215 or the switch operation unit 212.

If a user instruction to enable the wireless communication function of the first recording medium to be relay-recorded is input, the main control unit 210 enables the wireless communication function of the recording medium through the wireless control unit 302 in S604. If the wireless communication function is already enabled, this step is not executed. On the other hand, a user instruction is input in S603 that it is determined in S601 that the recording medium set with the first recording order does not have a wireless communication function or that the wireless communication function of the first recording medium to be relay-recorded is not enabled. If it is determined, the main control unit 210 moves the process to S503. Then, the main control unit 210 disables the wireless communication function through the wireless control unit 302. Note that this step is not executed when the wireless communication function is already disabled.
Since other processes are the same as those in the first embodiment, description thereof is omitted.

  As described above, in this embodiment, when the first recording medium used for relay recording has a wireless communication function, and there is an explicit instruction from the user, the wireless communication function can be enabled. did. This is because if the first recording medium used by the user for relay recording has a wireless communication function, the user may be willing to transmit the recorded content even if it is a part. In the present embodiment, user instructions can be accepted, and flexible relay recording that respects the user's intention can be performed. If the first recording medium used for relay recording does not have a wireless communication function, it is unlikely that the user has a positive intention to transmit the recorded content. Therefore, when the first recording medium has no wireless communication function and the second and subsequent recording media have a wireless communication function, the user is not inquired about the use of the wireless communication function.

  In step S601, it may be determined whether the wireless communication function of the first recording medium to be relay-recorded is enabled. In this case, the message of S602 may be displayed when it is valid, and the process may advance to S505 when it is invalid. This is because even if the first recording medium has a wireless communication function, if the wireless communication function is invalid, it is unlikely that the user has a positive intention to transmit the recorded content. It is.

(Other embodiments)
In the above-described embodiment, it has been described that data transfer by the wireless communication function is prevented by disabling the wireless communication function of the recording medium. However, the wireless communication function may remain valid, and data transfer may not be performed even if communication with the data transfer destination device becomes possible (that is, the data transfer function is disabled). In short, there is no limitation on the method as long as the data relay-recorded on the recording medium can be prevented from being transferred by the wireless communication function of the recording medium.

  In addition, when recording is started in the relay recording mode, but recording is not actually performed across the recording medium, the wireless communication function of the recording medium can be made effective. For example, in FIG. 4 showing the recording operation of the first embodiment, when a recording end instruction is detected in S508, the wireless communication function disabled in S503 can be automatically re-enabled. Accordingly, it is possible to avoid invalidating the wireless communication function until it is not necessary, and it is possible to effectively utilize the advantages of the recording medium having the wireless communication function.

  Alternatively, when the first recording medium recorded in the relay recording mode has a wireless communication function, and when recording ends within the range that fits in the recording medium, the wireless communication function is automatically set after the recording process is completed. You may comprise so that it may return to effective automatically.

  Furthermore, although the above-mentioned embodiment demonstrated the case where it applied to the apparatus with two recording media which can be used as a recording destination of relay recording, the apparatus which can perform relay recording with respect to three or more recording media The same applies to the above. It may be. For example, an internal storage device (semiconductor memory, magnetic recording medium, etc.) may be used for relay recording.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
