In this way, the system can display a display screen (warning screen) indicating a warning if the recording medium is attached before the execution operation by the user is performed. Therefore, if the recording medium is attached before the start of the initialization process, it is possible that the recording medium is attached by mistake, and the system warns.

(14) Further, in the system of the present embodiment, the processing means further detects the removal of the recording medium, and then further detects the attachment of the recording medium, and then initializes the recording medium. It is characterized by executing.

In this way, the system initializes the recording medium after the recording medium is attached / detached by the user after the warning is given. This makes it possible to provide a more secure system.

(15) Further, in the system of the present embodiment, the processing means executes a process of initializing the recording medium when it is determined that the recording medium matches the specific conditions.

In this way, the system does not initialize the recording medium uniformly, but executes a process of initializing when a specific condition is met. This makes it possible to prevent the user from initializing an unintended recording medium.

(16) Further, in the system of the present embodiment, the specific condition is a condition that the format format of the mounted recording medium matches the format format initialized by the processing means.

In this way, the system does not perform continuous initialization if the recording media are in different formats. Therefore, it is possible to prevent accidentally initializing a recording medium that is not in a predetermined format.

(17) Further, in the system of the present embodiment, the specific condition is a condition that the format format of the mounted recording medium matches the format format of the already formatted recording medium.

In this way, the system does not perform continuous initialization if the recording medium is in a different format than the other recording media. Therefore, it is possible to prevent accidentally initializing a recording medium that is not in a predetermined format.

(18) Further, in the system of the present embodiment, the specific condition is a condition that a predetermined period or more has passed from the recording date of the video data recorded on the recording medium.

In this way, the system can determine that it is highly necessary to record the video data when the date is short from the recording date, and can prevent the system from accidentally initializing the data.

(19) Further, in the system of the present embodiment, the specific condition is a condition that the event information associated with the video data recorded on the recording medium is not recorded.

In this way, when the event information is recorded on the recording medium, the system can prevent the system from initializing so as not to erase the video data.

(20) Further, in the system of the present embodiment, when it is determined that the recording medium does not match the specific conditions, the processing means outputs an operation screen for confirming whether or not to initialize the recording medium. It is characterized by.

In this way, the system can ask the user if the recording medium may be initialized if the recording medium does not meet the specific conditions. Therefore, even if the recording medium is continuously initialized, the user can confirm whether or not the recording medium can be initialized based on a specific condition.

It is characterized by outputting an operation screen for selecting whether to display the recording medium information recorded on the recording medium.

In this way, the system can confirm to the user whether or not the recording medium may be initialized when the event information associated with the video data recorded on the recording medium is recorded. Therefore, even if the recording medium is continuously initialized, the user can confirm whether the recording medium on which the event information is recorded may be initialized.

(22) Further, in the system of the present embodiment, the processing means can execute the first initialization process and the second initialization process, which are simply executed, as the initialization process. It is characterized in that the first initialization process is executed on the recording medium based on the detection of the detection means that the recording medium is attached.

In this way, when the recording medium is continuously initialized, the system executes the first initialization process which is simply executed. Therefore, when the user continuously initializes the recording medium, the recording medium can be efficiently initialized by simply performing the initialization.

(23) Further, in the system of the present embodiment, the first initialization process can be executed at a higher speed than the second initialization process.

In this way, the system can execute the first initialization process at a higher speed than the second initialization process. Therefore, when the user continuously initializes the recording medium, it can be executed quickly.

(24) Further, in the system of the present embodiment, the first initialization process is a logical format, and the second initialization process is a physical format.

In this way, the system can use the logical format, which is one of the high-speed methods, as the first initialization process. As a result, the user can easily perform the initialization at high speed in the first initialization, and can perform the initialization carefully even if it takes time in the second initialization.

(25) Further, in the system of the present embodiment, the first initialization process is a process of deleting the video data recorded on the recording medium.

In this way, the system may simply delete the video data as the first initialization process, and the initialization will be performed at high speed. Here, the deletion of the video data may be performed, for example, by rewriting the data in the FAT (File Allocation Table) area or changing the flag in the file management area.

(26) Further, in the system of the present embodiment, the recording medium is initialized in a format accessible by a standard file system of a computer, and the processing means is preliminarily loaded with video data of the recording medium. It is characterized by continuously generating virtual files in the recorded area.

In this way, the system will continuously generate dummy virtual files at the time of initialization. Therefore, files are continuously recorded in the sector of the area where the video data is recorded, and the system can replace and record the virtual file when recording the video data. Since the system records the video data in the continuous recording area in the recording area, it is possible to avoid the risk that the video data is not partially recorded or the recording of the video data fails.

(27) Further, in the system of the present embodiment, the recording medium is initialized in a format inaccessible by a standard file system of a computer, and the recording medium is management information for managing video data. The video data is recorded, and the processing means executes the initialization process by rewriting the management information.

In this way, the video data is recorded in an area inaccessible by the file system. Therefore, when the system performs the initialization process, by rewriting only the management information, the video data cannot be accessed, and the same effect as when the video data is deleted can be obtained.

(28) Further, in the system of the present embodiment, the recording medium has a first partition and a second partition, and video data is recorded in the second partition, and the second partition is recorded. One partition is characterized in that management information for managing video data is recorded.

In this way, it is possible to separate the area where the video data is recorded and the area where the management data is recorded. Further, at the time of initialization, the same effect as that of erasing the video data can be obtained only by erasing the data recorded in the first partition.

(29) Further, in the system of the present embodiment, the first partition is initialized in a format accessible by the file system, and the second partition is in a format inaccessible by the file system. It is characterized by being initialized with.

In this way, it is possible to separate the area where the video data is recorded and the area where the management data is recorded. Further, at the time of initialization, the same effect as that of erasing the video data can be obtained only by erasing the data recorded in the first partition.

(30) Further, in the system of the present embodiment, when there are a first recording medium and a second recording medium as the recording medium that has been detected to be mounted, the processing means is the first. It is characterized in that the process of initializing the second recording medium is executed after the first recording medium is initialized based on the detection that the recording medium is attached.

In this way, the system can execute the process of initializing the plurality of recording media. Therefore, when a certain recording medium is being initialized, the recording medium of another detection means can be attached and detached, so that the initialization can be performed more efficiently for the user.

(31) Further, the system of the present embodiment is further provided with a history management means for managing the history of executing the process initialized by the processing means.

In this way, the system can manage the history of executing the initialization process. Therefore, it becomes clear when the initialized recording medium is initialized, and a highly secure system is provided from the viewpoint of security.

(32) Further, the system of the present embodiment is further provided with a report output means for outputting a report based on the history managed by the history management means.

In this way, the system can output a history-based report. Therefore, it is possible to confirm when the initialized recording medium is initialized in the report, and a highly secure system is provided from the viewpoint of security.

(33) Further, in the system of the present embodiment, the history managed by the history management means includes at least the date and time when the initialization process is executed and the identification information for identifying the recording medium. It is a feature.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The embodiment shown below is one embodiment that provides the present invention, and the content of the present invention is not limitedly interpreted based on the following description.

[0. Background to the idea of the invention of the present application and outline of the invention of the present application]
The invention of the present application was inspired by the inventor of the present application based on the background described below. For public-use cameras (for example, drive recorders) in public transportation such as trains, buses, taxis, airplanes, monorails, and linear motor cars, the outflow of images taken by the cameras is regarded as a problem. External leakage occurs, for example, when video data recorded on an SD card (an example of a memory card) is copied to another SD card. Therefore, it is conceivable to adopt a method of formatting and initializing a newly purchased SD card using the SD card for which the initial setting for writing the setting information indicating the contents of the operation setting of the camera has been completed as the copy source.

However, in this case, the number of cameras for front surveillance alone is required as many as the number of cameras installed by the SD card, and if it is also used for crime prevention in the car, the number of cameras will increase and the number of required SD cards will increase. To increase. For this reason, there is a request that the work be completed in as short a time as possible. In addition, in performing such regular formatting of the SD card, there is a problem that the image recorded on the SD card can be viewed if this is used due to the specifications of the software that displays the image recorded on the SD card. be.

Therefore, it is possible to introduce an SD duplicator and copy the setting information indicating the contents of the operation settings of the SD card of the copy source (master) to the SD card of the copy destination (for example, a newly purchased one). Conceivable. However, such a method has the following problems (1) and (2).
(1) When using a duplicator, it is desirable to use SD cards of the same manufacturer and quality at the same time, and knowledge that can confirm the SD status after copying at the cluster level is required.
(2) When the master SD card is copied with the duplicator, the information and traces in the copy destination SD card such as the number of overwrites are also erased, so that analysis cannot be performed when a problem occurs.

In view of the above problems and the fact that it is necessary to be careful in handling images from public-use cameras and it is a problem if the images are viewed at the time of formatting, the inventor of the present application is mainly for corporations. , I thought about preparing it as "regular format" software for administrators. This software is, for example, a format tool that specializes only in formatting. This tool formats data that you don't want to see or that you shouldn't see with an application program that you can't see and erase without looking at the video. This tool is a formatted version of the SD card setting tool. The setting tool needs to be updated for each new model, but it is conceivable that such a format tool will not be updated. The procedure is to incorporate safe removal into the software, (1) start the software, (2) insert the SD card, (3) press the regular format button of the software, (4) format is completed in an instant. Display, (5) remove the SD card, (6) insert the next SD card, and repeat steps (3) to (6) thereafter. The inventor of the present application came up with the idea of the present application based on the idea of enabling the administrator to complete the work easily and in a short time by the above method.

[1. First Embodiment]
[1.1 System Overview]
System 1 is a diagram showing an outline of the system according to the present embodiment. As shown in FIG. 1A, the system 1 has a processing device 10 capable of reading and writing data to and from a memory card 250, which is a recording medium. The processing device 10 has a function of initializing the memory card 250. When video data is recorded on the memory card 250, the processing device 10 is configured so that it is not viewed by a person who uses the processing device 10 and is not qualified to view the video. For example, from the viewpoint of privacy and security. Therefore, for example, the video playback function of the processing device 10 may be limited (for example, the playback function does not operate), or the video data may be configured so that it cannot be played back by the playback function (for example). , Data format / application of encryption technology, etc.), the processing device 10 may not have a video reproduction function. Further, the processing device 10 may be connected to the memory card reader 15 via an interface such as USB (Universal Serial Bus). In this case, the processing device 10 reads and writes data to and from the memory card 250 via the memory card reader 15. The processing device 10 is realized by a personal computer in the present embodiment, but is realized by a recording device 30 that records images on the memory card 250, a dedicated machine manufactured for performing initialization processing of the memory card 250, or the like. May be done.

Further, the recording medium may be, for example, a USB memory. The USB memory is connected to the processing device 10 or the USB interface. Hereinafter, in the present embodiment, the memory card 250 will be described as an example as the recording medium.

Further, the system 1 can also be realized by a single device such as the processing device 20 as shown in FIG. 1 (b). In this case, for example, the processing device 20 is provided with a display unit 22 and a plurality of memory card readers 24. That is, the processing device 20 may be a device such as a gang programmer or a gang reader / writer.

The memory card 250, which is a recording medium, is a recording medium generally called an SD card (registered trademark) or a microSD card. The memory card 250 is mainly composed of a semiconductor as a recording medium, but if it is a recording medium that can be connected to another device, it may be another recording medium (for example, a magnetic medium, a magneto-optical medium, or the like). May be good.

Here, in the present embodiment, the memory card 250 is used as an example in a recording device that constantly captures an image as content and records it constantly or as needed. For example, as shown in FIG. 1 (c), the recording device 30 is provided as a drive recorder on the front portion of a vehicle such as an automobile or a railroad, and photographs and records the front of the vehicle. The recording device 30 may record the image taken by the own device and the image of another camera acquired via a wired or wireless communication path. The recording device 30 has, for example, photographed at least one of the inside of the vehicle, the side of the vehicle (left or right with respect to the traveling direction), and the rear of the vehicle, in addition to the front of the vehicle photographed by the own device. Acquire and record video from other cameras. In the present embodiment, the recording device 30 will be described using a drive recorder as an example, but in addition to this, a surveillance camera that monitors a predetermined area such as a work area of a factory and a security camera that photographs and records the inside of a store are always used. It may be a device for recording a captured image or a device for recording a log of the device (for example, an operation log of a machine machine installed in a factory or the like).

The recording device 30 includes a photographing device 32. The photographing device 32 is, for example, a device having a built-in CCD (Charge Coupled Device) camera. An image is constantly captured by the photographing device 32 and recorded on the memory card 250.

The recording device 30 may record the video that is constantly being photographed as it is as video data on the memory card 250, or may record only before and after the event occurs on the memory card 250. Further, the recording device 30 may switch the recording method of the video data according to the state of the vehicle. For example, the recording device 30 records a video constantly captured as video data on the memory card 250 when power is supplied from an external device such as a vehicle (for example, the engine is operating). Further, when the power is not supplied from the external device (for example, the engine is stopped), the recording device executes interval shooting and records the video at predetermined time intervals on the memory card 250 as video data.

Further, the recording device 30 may record only the video data at the time of the event occurrence and the predetermined time before and after the event occurrence, without constantly recording the video data. The event may be a trigger for specially recording the video data in the recording device 30.

The recording device 30 is, for example, when an impact is applied to the vehicle in which the recording device 30 is installed (specifically, when the acceleration detected by the acceleration sensor of the recording device 30 is an acceleration of a predetermined pattern (for example,). (When the waveform showing the temporal change of acceleration satisfies a predetermined condition) or when it is equal to or more than the threshold value) is detected as an event. Specifically, if the threshold value of acceleration (gravitational acceleration) is set to 0.3G, the acceleration is detected at 0.3G or more, or twice the acceleration detected during normal deceleration. The case where the above acceleration is detected may be detected as an event. The numerical value as the threshold value is an example, and may be set to another value such as 0.4G.

Thereby, for example, in a vehicle in which the recording device 30 is installed, an accident such as a timing at which sudden braking (sudden braking, sudden start, sharp curve) is detected, contact / rear-end collision can be detected as an event. In addition to the impact, the recording device 30 also uses, for example, the driver's condition (for example, looking away, dozing, etc.) and the vehicle's running condition (for example, long-time driving without a break, staggering, overspeeding, reverse driving detection, etc. ), The event may be detected based on the surrounding conditions of the vehicle (for example, pedestrian detection, bicycle detection, signal recognition, etc.).

Further, in the case of a drive recorder installed in a vehicle, the recording device 30 may acquire information about the vehicle and record it together with a recording medium. For example, the recording device 30 is acquired by using GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo, Quasi-Zenith Satellite (QZSS), etc., which are Global Positioning Satellite Systems (GNSS). The position information, the speed information regarding the speed of the vehicle, and the acceleration information may be recorded in the memory card 250. Further, the recording device 30 may record information (city / ward / town / village, station name, address, etc.) related to the place name corresponding to the position information on the memory card 250.

Here, the memory card 250 is formatted in a predetermined format by the initialization process, and the recorded video data or the like is erased (initialized). If the memory card 250 is initialized, the recording device 30 can record, for example, video data as content.

The initialization process is a process for initializing the recording medium. Initializing the recording medium means setting the recording medium for a predetermined system. In the present embodiment, the initial setting of the recording medium provides setting information indicating the contents of the operation setting in order to make the recording medium usable by a predetermined system (for example, a state in which video data can be read and written). It may be said to write on the recording medium. Not limited to this, initializing the recording medium may be one or more of writing the setting information to the recording medium, formatting the recording medium, and putting the recording medium into a specific file state. good. In the present embodiment, the main body that initially sets the recording medium and the main body that uses the recording medium are different, the former being the processing device 10 and the latter being the recording device 30. If the entity that initializes the recording medium cannot operate according to the operation settings set by the initial settings, for example, if it does not support the format described later, the entity that initializes the recording medium cannot use it. The recording medium is initially set so that it can be used by the subject who uses the recording medium. However, the operation settings corresponding to both the main body that initially sets the recording medium and the main body that uses the recording medium may be set by this initial setting. For example, the case where both of them support the format for a general-purpose personal computer is an example of this case.

The initial setting of this embodiment involves formatting the recording medium. In the present embodiment, formatting the recording medium means putting the recording medium in a state in which the recording device 30 can read and write video data. For example, the processing device 10 formats the memory card 250 in a designated format to generate an area for recording video data or the like on the memory card 250.

In the present embodiment, initializing the recording medium may also include making it unrecognizable that video data is recorded on the recording medium. The state in which the video data cannot be recognized means, for example, that when the user confirms the video data on the recording medium with the playback device 40, the video data cannot be reproduced or the number of video data recorded on the recording medium is 0. It is good to say the state displayed as a matter. The state in which the video data cannot be reproduced means a state in which the video data to be reproduced does not exist, a state in which the video data to be reproduced is not recognized, a state in which the video data is concealed, and the like.

When the processing device 10 executes the initialization process, the memory card 250, which is a recording medium, is initialized. Here, the initialization includes a simple first initialization process that does not take time and a second initialization process (complete initialization process) that takes a relatively long time. For example, the first initialization process takes time on the order of microseconds, and the second initialization process takes time on the order of milliseconds. On the other hand, the second initialization process is more desirable than the first initialization process in order to prevent the video recorded on the memory card 250 from being viewed. In this sense, simple means that, for example, the algorithm related to the initialization process is simple.

For example, when the processing device 10 executes the first initialization process, it does not perform the above-mentioned format, but deletes only the video data or puts new dummy data in the area where the video data is recorded. Overwrite. Further, the processing device 10 deletes or rewrites the management information indicating that the video data is recorded, so that the video data recorded on the recording medium cannot be recognized.

That is, in the processing device 10, in the first initialization process, regardless of whether or not the video data is recorded on the recording medium, the video data cannot be displayed on another device (for example, the playback device 40). , It means to make it unreadable. Further, in the initialization process, the video data may be concealed so that it cannot be read by another device.

Further, when the processing device 10 executes the second initialization process, the processing device 10 erases the video data from the recording medium. For example, the video data is prevented from remaining on the recording medium by executing the initialization process after performing the above-mentioned format or rewriting the sector of the recording medium. However, the time required for the processing is relatively longer in the second initialization process than in the first initialization process.

In the following embodiments, when it is simply described as initialization, it means the first initialization, and when it is described as complete initialization, it means the second initialization. Further, if it is not necessary to distinguish the processes in the embodiment, either initialization process may be executed.

The video data recorded on the memory card 250 can be reproduced by another device. For example, when the memory card 250 is attached to the playback device 40 shown in FIG. 1 (c), the playback device 40 reproduces the video data recorded on the memory card.

The playback device 40 is an information processing device such as a computer or a tablet. The playback device 40 can read and play back the video data recorded on the memory card 250 by executing the playback application.

The playback device 40 may execute a dedicated playback application, or uses a playback function installed in an OS (for example, Windows (registered trademark), Android (registered trademark), Linux (registered trademark), etc.). You may. Further, the playback device 40 covers an area that cannot be accessed by a file system (for example, FAT32 or NTFS (NT File System, HFS (Hierarchical File System))) that can be realized by the OS as standard by using a playback application. Will also be accessible.

[1.2 Functional configuration]
FIG. 2 is a diagram illustrating a functional configuration of the processing device 10. Hereinafter, the functional configuration of the processing device 10 will be described.

The control unit 100 is a functional unit for controlling the entire processing device 10. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 110, and is composed of, for example, one or a plurality of arithmetic units (for example, a CPU (Central Processing Unit)). NS.

Further, the control unit 100 functions as the initialization unit 102 and the complete initialization unit 104 by reading and executing the program stored in the storage unit 110. The control unit 100 functions as a processing means by reading the program and executing the processing. The processing means may be a general-purpose arithmetic unit such as the control unit 100, or may be another control device (controller) that executes each process.

The initialization unit 102 initializes the memory card 250, which is a recording medium, by executing the initialization process (first initialization process) (first initialization). When the initialization unit 102 initializes the memory card 250, another device (for example, the playback device 40) cannot read or reproduce the video data from the memory card 250. Further, after the first initialization process of the memory card 250 is completed, the initialization unit 102 performs initialization only by attaching and detaching the memory card 250 without going through other operations (continuous initialization process described later). Has a function to perform.

Here, the first initialization process is, for example, a process of deleting video data or a process of performing logical formatting. Further, as a method in which the first initialization process deletes the video data, the information in the file management area such as FAT is simply deleted, the management information that manages the video data is rewritten, or the video data is recorded. A method of rewriting the flag indicating that the data is displayed can be considered. That is, in the first initialization process, the video data is deleted or the video data is concealed so that the playback device 40 or the like cannot read or play the video data recorded on the memory card 250. do.

The complete initialization unit 104 completely initializes (second initialization) the memory card 250, which is a recording medium, by executing the complete initialization process (second initialization process). For example, in the complete initialization process, the first initialization process is executed after formatting the memory card 250, the area required after formatting the memory card 250, and the area required as the initial state are required. Record data. Further, the complete initialization unit 104 erases the data including the video data stored in the memory card 250 at once by transmitting the reset command to the memory card 250.

Further, in the second initialization process, the format of the memory card 250 may be different between before and after the initialization, and if they are different, the second initialization process may not be performed. Further, for example, when the first initialization process performs the logical format, the second initialization process performs the physical format. Further, for example, when the first initialization process only rewrites the management information of the video data and the flag, the second initialization process recreates the recording area or creates a new partition. You may go.

Here, the initialization process (first initialization process) performed by the initialization unit 102 can be executed at a higher speed than the initialization process (second initialization process) performed by the complete initialization unit 104.

The first initialization process may be performed by, for example, the process described in JP-A-2017-135436. In this case, in the first initialization process, the memory card 250 is stored in the management area as a format count master value indicating the number of times the memory card 250 has been initialized, and the video is recorded at consecutive addresses in the recording area of the memory card 250. , The format count master value is posted as the format count value (also referred to as the format counter) for each video, and the video data in which the format count value different from the current format count master value is recorded is treated as deleted. It is good. In this way, the time required for formatting can be shortened. Further, the difference in processing time between the first processing process and the second processing process does not necessarily have to be a difference that the user can clearly feel. Even if you cannot feel the difference in the initialization processing time of one memory card 250, for example, when initializing a large number of memory cards 250 such as 100 or 1000 cards, the work related to the initialization There is a possibility that the user can realize the difference in the time required for the operation. As described above, the specific processing content does not matter as long as the first initialization process can be executed more easily than the second initialization process.

Further, the initialization unit 102 and the complete initialization unit 104 can initialize a plurality of types of memory cards 250. The type is, for example, the type of the SD card, which is the memory card 250, such as the manufacturing time, the manufacturer, and the quality. As described above, the initialization unit 102 and the complete initialization unit 104 have a function of initializing a plurality of memory cards 250 having the same standard but different types.

As described above, the processing device 10 does not reproduce the video recorded on the memory card 250 when the memory card 250 is initialized. In this embodiment, there is no playback function in the started program. As described above, the program of the present embodiment is a program dedicated to the initialization of the memory card 250 and has no playback function. In place of or in addition to this, when the processing device 10 has a function of reproducing an image, the control unit 100 further refers to a means for restricting the reproduction of the image recorded on the memory card 250 (hereinafter referred to as a "restriction unit"). (Not shown) may be provided. The limiting unit may control, for example, to prevent the reproduction function of the processing device 10 from operating, but to prevent the image recorded on the memory card 250 from being displayed on the display unit 130. The limiting unit may further have a function of controlling the processing device 10 so as not to output the video data to an external device via the communication unit 140 and other video output units. The limiting portion may be realized by either hardware or software. Further, the function to reproduce (for example, a reproduction program) may have the function of limiting.

The storage unit 110 is a functional unit that stores various programs and various data necessary for the operation of the processing device 10. The storage unit 110 is composed of, for example, a semiconductor memory SSD (Solid State Drive), an HDD (Hard Disk Drive), or the like.

Further, the storage unit 110 stores the user information 112 and the history data 114 as needed. The user information 112 stores information about the user. For example, it stores authentication information such as a user ID and a password.

The history data 114 stores information regarding the history when the processing device 10 executes the process. For example, the executor who executed the process, the date and time, and the execution contents are stored. Further, the history data 114 may also store information about the memory card 250 (for example, information such as identification information of the memory card and date and time of video data recorded before initialization).

The input unit 120 receives input from the user. For example, it is composed of a hardware switch such as a switch / key, a touch panel that receives an input of a software switch displayed on the display unit 130, and the like. Further, the input unit 120 may be an input device such as a mouse or a keyboard connected to the outside.

The display unit 130 displays various states of the processing device 10 and displays the state of operation input. For example, it is composed of a liquid crystal display (LCD), an organic EL panel, electronic paper using an electrophoresis method, and the like. In addition, the display unit 130 displays a display screen. Here, the display screen is displayed on the display unit 130, and may be the entire display displayed on the display of the display unit 130, or a part of the area may be referred to as a display screen. For example, the window display or the dialog displayed on the display unit 130 may be referred to as a display screen, or the entire including them may be referred to as a display screen. The display screen may be a screen displayed in a certain area.

The communication unit 140 communicates with another device or communicates with another device via a network. For example, interfaces such as USB (Universal Serial Bus) and HDMI (registered trademark) (High-Definition Multimedia Interface), NIC (Network Interface Card) for connecting to wired / wireless LAN, LTE (Long Term Evolution) / 4G. A communication module for connecting to a mobile communication network such as / 5G is included.

The recording unit 150 writes data to or reads data from the recording medium. The recording unit 150 is a so-called memory card reader, and the memory card is detachably configured as one of the recording media. Further, the processing device 10 is configured as a card slot, and may detect attachment / detachment (attachment / detachment) of the memory card 250.

That is, the recording unit 150 also functions as a detection means for the memory card 250. When it is detected that the memory card 250 is installed in the recording unit 150 (card slot), a signal indicating that the memory card 250 is installed is transmitted to the control unit 100. Similarly, when it is detected that the memory card has been removed from the recording unit 150 (card slot), a signal indicating that the memory card has been removed is transmitted to the control unit 100. The control unit 100 detects (determines) that the memory card 250 has been installed and that the memory card 250 has been removed, based on the signal from the recording unit 150.

Further, the recording unit 150 may be wirelessly connected to the memory card. For example, the recording unit 150 may be connected to the memory card via short-range wireless communication such as NFC (Near Field Communication). In this case, mounting the memory card means connecting to the memory card (establishing communication). Also, removing the memory card means disconnecting it from the memory card.

The input unit 120, the display unit 130, the communication unit 140, and the recording unit 150 will be described as being built in the processing device 10 for convenience of explanation, but an external device may be connected if necessary. For example, by connecting a memory card reader to the communication unit 140 (USB interface), the memory card reader functions as the recording unit 150.

That is, the input unit 120, the display unit 130, the communication unit 140, and the recording unit 150 may be provided with the necessary control devices, and may function integrally with the devices connected to the outside.

The memory card 250 is a portable recording medium, for example, an SD card, a microSD card, a CF card, or the like. The memory card 250 may be able to read and write data by connecting to the recording unit 150.

Further, the memory card 250 records memory card information 252, which is recording medium information which is information about a recording medium, and video data 254, which is content data. The memory card information 252 is information about a memory card or device other than the content data. For example, it is possible to record information such as a memory card identification number and capacity, and other information (for example, format format, partition information, etc.).

Further, the memory card information 252 can include information regarding the setting of the recording device 30. For example, the image quality, file format, and the like when the recording device 30 shoots are recorded in the memory card information 252 as setting information. When the memory card 250 is attached, the recording device 30 can read the setting information recorded on the memory card 250 and set the operation of the recording device 30.

Further, the memory card information 252 can include various information recorded by the recording device 30 in association with the video data. For example, as the information of the recording device 30, the model name of the recording device 30, the type of video data (type of constantly recorded video data, video data at the time of event detection, etc.), and event information can be recorded. In addition, information on vehicles on which the recording device 30 is installed (for example, vehicle numbers, railway / bus / taxi vehicle numbers, route names, positions), acquired position information, impact information (acceleration, etc.), and speed. Information such as information can be included.

These memory card information may be recorded corresponding to the video data, or may be simply recorded corresponding to the memory card 250. For example, the position information, speed information, impact information, and the like acquired by the recording device 30 are recorded in association with the video data (for example, in association with the recording time of the video data). On the other hand, the number of the automobile, the number of the vehicle on which the recording device 30 is installed, the route name, etc. are recorded regardless of the video data.

Further, as the video data 254, preferably, the video captured by the recording device 30 equipped with the memory card 250 is recorded as video data. In the present embodiment, the recording device 30 will be described by taking video data as an example of the content data to be recorded in the memory card 250, but may be still image data, audio data, or the like.

Further, the video data 254 may be any data that can be reproduced by the reproduction device 40. For example, it is a predetermined moving image format such as MPEG format or AVI format. Further, the moving image data in a unique format that can be reproduced by the reproduction application executed by the reproduction device 40 may be used.

[1.3 Format]
Next, the format of the memory card 250 will be described. The processing device 10 can format the memory card 250 by the control unit 100 executing the formatting process. The processing device 10 can generate a memory card 250 having the following format format by executing the format processing. Although the format processing will be described as the complete initialization unit 104 executing the format processing, the initialization unit 102 may execute the format processing. Here, the format of the memory card applicable in the present embodiment will be described.

(First format format)
As shown in FIG. 3, the first format is a format in which a user area is secured in a memory card and a video file to be recorded in this user area is generated in advance as a virtual file (dummy data). .. The control unit 100 formats the memory card 250 using the FAT file system. As a result, the memory card 250 generates the following areas.

MBR (Master Boot Record). This area is reserved in the area of the first sector of the memory card and stores information about the partition.
BPB (BIOS Parameter Block). It is an area for storing information about FAT and RDE secured as a later area.
FAT (File Allocation Table). An area that stores information that indicates the location of a file.
RDE (Root Directory Entry). This area stores information about files and folders that exist in the root directory.

User data area. This is an area for recording data files created and used by users. In the first format, a virtual file with a data name is generated and recorded as dummy data in a continuous area (for example, a continuous sector area) of the user data area. When recording the video data, the recording device 30 replaces (rewrites) the dummy data already recorded in the memory card and records the video data.

As a result, dummy data is recorded in continuous sectors at the time of initialization, and video data is also recorded in continuous sectors. Generally, since the recording device 30 writes while performing moving image processing such as constant shooting, it is preferable to record video data in a continuous area in order to prevent dropped frames and recording failure.

That is, if dummy data is recorded in advance as a reserved area for recording video data, the recording device 30 can record the video data without any problem by replacing the dummy data. Further, since the recording device 30 reserves a continuous area as dummy data in advance on the recording medium as a reserved area for video data, it is possible to prevent fragmentation.

Further, as the dummy data, a plurality of files having the same size as the video data may be generated. For example, when the data size of the video data is 100 MB per file, a plurality of 100 MB dummy data are generated and recorded.

Further, the dummy data may generate a large size and a small size. For example, when the recording device 30 records high-resolution and low-resolution video data, or records shooting information (for example, information on latitude / longitude, altitude, acceleration, speed, etc.) as shooting information, Dummy data of a size corresponding to the corresponding data may be generated.

Further, the recording device 30 may record the high-resolution video data and the low-resolution video data separately according to the size of the image, the compression method, the encoding method, and the like.

Further, when the control unit 100 generates and records a plurality of sizes as dummy data, the large and small sizes may be recorded alternately, or the small dummy data may be continuously recorded first, and then the large size may be recorded. Dummy data may be continuously recorded.

The first format is characterized in that continuous dummy data is recorded in the user data in advance in the user data area. Therefore, it suffices if a user area for recording dummy data can be secured, and the format in the file system may be executed using other file systems such as NTFS, exFAT, and HFS in addition to FAT.

(Second format)
As shown in FIG. 4, the second format format is a format method in which a video data recording area in a state of being usable by another system is secured in the user data area of the memory card 250. In this case, the video data recording area on which the video data is recorded cannot be accessed in a normal file system (for example, FAT32).

Further, in the video data recording area, the video data is sequentially recorded. The video data recorded in the video data recording area is managed based on the management information recorded in the data management area. For example, the playback device 40 refers to the management information in the playback application and identifies the position of the video data in the video data recording area.

Here, the management information may be information recorded in association with the date and time when the video data was recorded, the management flag, and the address where the video data is recorded. The playback device 40 can identify the position where the video data is recorded in the video data recording area and read the video data based on the management information.

At this time, the playback device 40 may switch the output of the video data by the management flag. For example, when the management flag is "1", the playback device 40 recognizes that the video data is effectively recorded, reads the video data, and reproduces the video data. Further, when the management flag is "0", the playback device 40 recognizes that the video data is not effectively recorded, and cannot reproduce the video data. The management flag may be recorded for each video data generated for each predetermined size. The management flag may be added before and / or after the video data.

Therefore, in the case of the second format, when the initialization unit 102 performs initialization (first initialization), all the management flags may be simply rewritten to "0".

The video data recording area is an area that cannot be accessed by a normal file system, but may be an area that can be accessed by a normal file system. In this case, one area in which data can be recorded in a large sequential manner is secured in the area. The processing device 10, the recording device 30, and the playback device 40 can read and play back video data in an area where data can be sequentially recorded. In this case, the configuration may appear as a single file from a terminal device having only a normal file system that cannot be played back.

(Third format method)
As shown in FIG. 5, the third format method is a format method when a plurality of partitions are used in the memory card 250. Specifically, the control unit 100 secures a plurality of partition areas in the memory card 250. Then, the control unit 100 secures a video data recording area in the user data area of each partition area. Further, the control unit 100 gives information indicating the partition to the MBR of the memory card 250.

Further, the size of the video data recording area secured in each partition may be changed according to the size of the recorded video data. For example, the control unit 100 secures a small area for the first recording area as compared with the second recording area. In this case, the recording device 30 records low-resolution video data in the video data recording area of the first recording area. Further, the recording device 30 records high-resolution video data in the video data recording area of the second recording area. In the area of a plurality of partitions and / or the video data recording area secured therein, the difference in the size of the area may be, for example, a difference of 2 times or 3 times, or a 1-digit or 2-digit order. It may be the difference between. Further, the size of the areas of the plurality of partitions or the video data recording areas secured in these may not be the same in each format, and the control unit 100 may, for example, regularly or in response to a user's instruction. May be changed.

Further, as the video data recording area secured in the third format method, either the first format method or the second format method may be used or may be combined.

Further, for each partition, it may be set whether or not it can be accessed from the file system of the OS. For example, other than video data such as memory card information and management information, it is recorded in the first partition as usual. However, the video data is recorded in the second partition.

There may be a difference in the method that the playback device 40 or the like can access for each partition. For example, the first partition having a small capacity may be accessible by the file system having the OS standard function, but the second partition may not be accessible by the file system having the OS standard function.

[1.4 Explanation of processing]
The processing in this embodiment will be described with reference to FIG. In the present embodiment, when the attachment (connection) of the memory card 250, which is a recording medium, is detected, the initialization process is continuously executed.

First, the control unit 100 operates a program for executing the initialization process. In the present embodiment, the control unit 100 operates the program in response to an operation (for example, double-clicking) of selecting an icon corresponding to the program displayed on the display unit 130. When the program is activated, the control unit 100 displays the insertion screen on the display unit 130 (step S102). The insert screen is a UI (user interface) that prompts the user to insert a memory card. The control unit 100 uses an insertion screen as a method of prompting the insertion of the memory card, but other than the insertion screen, a voice notification or a lamp notification may be performed.

Subsequently, when the control unit 100 detects that the memory card 250, which is a recording medium, has been attached by the recording unit 150 (step S104; Yes), the control unit 100 executes the initialization process (step S106).

The control unit 100 waits until the memory card is installed (step S104; No), but if the user performs a stop operation, this process may be stopped.

The initialization process in step S106 is a process executed by the initialization unit 102 (control unit 100). From the viewpoint of continuously initializing a plurality of memory cards, it is preferable to execute the first initialization process that does not take much time for initialization, but the second initialization process may be executed.

When the initialization of the memory card 250 is completed (that is, when the initialization process is completed), the control unit 100 displays a completion screen indicating that the initialization is completed on the display unit 130 (step S108; Yes → step S110). ).

The completion screen is one of the methods for notifying the user that the initialization is completed. It is preferable that the completion screen is a little more flashy than the insertion screen, and the size is changed so that the screen form is clearly different. This is because it is easy to attract the user's attention. Instead of displaying the completion screen, the control unit 100 may use a method such as a voice notification or a notification to another device.

When the control unit 100 detects that the memory card 250 has been removed (step S112), the control unit 100 displays the insertion screen again (step S112; Yes → step S102). The control unit 100 may hide the second and subsequent insertion screens. In this case, the control unit 100 transitions the process to step S104 instead of step S102. Therefore, the user can continuously initialize the memory card 250 simply by inserting and removing the card.

The control unit 100 in the present embodiment detects the attachment / detachment of the memory card 250, for example, detects the attachment / detachment of the memory card 250 in the card slot of the recording unit 150, or receives a signal indicating attachment / detachment from the memory card reader. It is good to say that. When the memory card 250 is connected by NFC or the like, the control unit 100 may detect the attachment when the communication with the memory card 250 is established, and may detect the removal when the communication is disconnected.

Further, in steps S104 to S106, the control unit 100 detects the installation of the memory card 250 and executes the initialization process, but the initialization is possible (initialization is possible in the first initialization). The initialization process may be executed only for a memory card.

Here, it is preferable to determine whether the memory card that can be initialized is a memory card that can recognize the format of the format or a memory card that records video data of a specific data format.

For example, when the control unit 100 detects that a memory card formatted by the third format method is installed next to the memory card formatted by the first format method described above, the control unit 100 initializes the memory card 250. do not.

As described above, according to the process of the present embodiment, when the control unit 100 detects the attachment of the memory card 250, the control unit 100 executes the initialization process. Further, the control unit 100 detects the removal of the memory card 250, and when the memory card 250 is installed again, the control unit 100 executes the initialization process. Therefore, the user can continuously initialize the attached memory cards 250 by sequentially attaching and detaching the plurality of memory cards 250.

Note that these processes may be provided as a program or as hardware. It may be provided as a format tool APP (application program) for formatting a recording medium such as a memory card.

[1.5 Operation example]
An operation example when the control unit 100 is executing the process of FIG. 6 will be described with reference to FIG. 7. FIG. 7 is a diagram for explaining an example of a display screen displayed on the display unit 130. In some of the display screens described below, the words "Format" and "FORMAT" are used for the convenience of the user, but instead, the words "initialization" or "initialization process" are used. May be used.

FIG. 7A is an example of the display screen W100 displayed on the display unit 130 in the present embodiment. The display screen W100 may be displayed superimposed on another screen, or may be displayed as a single screen. The control unit 100 displays a message "Please insert a memory card" as shown on the display screen W100. That is, the display screen W100 is an insertion screen (SD insertion screen) that prompts the user to insert a recording medium (for example, an SD card).

Further, the button R100 is displayed on the display screen W100. When the user performs a selection operation (for example, a touch operation or a click operation) on the button R100, the process is stopped. In addition to the button R100, a button for executing processing may be displayed on the display screen W100, or the button R100 may not be displayed.

When the control unit 100 detects that the memory card 250 is installed, the control unit 100 executes an initialization process. Then, when the initialization of the memory card 250 is completed, the transition to the display screen W110 of FIG. 7B is performed.

The display screen W110 is an end screen for notifying the user that the initialization process of the memory card is completed. For example, as shown in the display screen W110 of FIG. 7B, the control unit 100 displays a message indicating that the initialization process "Format has ended" has been completed. In addition, the control unit 100 also displays a message "Please remove the memory card" as a message prompting the next operation.

Here, when the user removes the memory card, the transition from the display screen W110 of FIG. 7B to the display screen W100 of FIG. 7A again. That is, the transition is made so that the insertion screen is displayed again from the end screen. In this way, the user simply inserts and removes the memory card, and the memory card is continuously initialized. The memory card may be attached / detached while the insertion screen is not displayed and the end screen is displayed.

Instead of the display method of transitioning to the display screen W100 again after the display screen W110 is displayed, a method of displaying a single screen including the information included in the display screen W110 and the display screen W100 may be adopted. .. In this case, the control unit 100, for example, displays a message indicating that the initialization process "Format has ended", "Remove the memory card and insert another memory card" on the single screen. A message prompting the next action is displayed. The control unit 100 starts the initialization process when the memory card 250 is removed and the next memory card 250 is inserted while the single screen is being displayed.

The control unit 100 may execute a different display mode or method when notifying the user that the initialization process has been completed. For example, in the display screen W120 of FIG. 7C, the font size of the message has changed. As shown on the display screen W120, the control unit 100 displays "FORMAT end!" In a larger font size than the display screen W110.

In addition to this, for example, the control unit 100 may change the display mode such as changing the color of the message, changing the background color, and blinking the display. In addition, a notification sound may be output, an icon may be displayed separately, or the window display may be surrounded by a thick line. The display mode used by the control unit 100 may be a method for informing the user that the initialization process has been completed in an easy-to-understand manner.

Further, when the memory card 250 cannot be initialized (not initialized), the control unit 100 may display to that effect on the display screen. For example, if the format of the memory card 250 is different from the immediately preceding one or the set one, or if the type of recorded video data is different, that fact is displayed.

Specifically, the control unit 100 displays a message such as "The format format is different!" As shown in the display screen W130 of FIG. 7D, for example. The control unit 100 may display on the display screen that the format format is different or that the format of the recorded video data is different as a message.

Further, as shown in FIG. 7D, the control unit 100 may display a button R130 for forcibly initializing. For example, when the button R130 is selected by the user, the control unit 100 continues the initialization process as it is even if the format format is different or the video data format is different. In this case, since the user has confirmed once, it is possible to prevent the memory card 250 from being initialized by mistake.

In this case, the control unit 100 may switch the initial processing from the first initialization process to the second initialization process (complete initialization process) and execute the initialization process according to the format. May be executed. For example, when the format of the video data currently recorded on the memory card is different from that of the other memory card, the control unit 100 may record dummy data corresponding to the format of the video data currently recorded on the other memory card. good. Further, dummy data may be generated and recorded in the format of the video data predetermined in the initialization process or the format of the video data recorded in the memory card initialized immediately before.

The trigger for operating the program is not limited to accepting the operation of selecting an icon as described above. For example, the control unit 100 may operate the program when it detects that the first memory card 250 has been inserted into the card slot of the recording unit 150. Further, the control unit 100 does not reproduce the video recorded on the memory card 250 during the period of executing the process of FIG. For example, the program for executing the process described with reference to FIG. 6 does not include a function of reproducing a video. Even if the processing device 10 has a video playback function due to another program (for example, an OS, a viewer or other video playback program) or another function, the processing device 10 does not play the video. For example, the control unit 100 of the processing device 10 may limit the reproduction of the video recorded on the memory card 250 by the function of the program for executing the processing described with reference to FIG. The control unit 100 controls, for example, to prevent the reproduction function of the processing device 10 from being activated, but to prevent the image recorded on the memory card 250 from being displayed on the display unit 130. The control unit 100 may further control the processing device 10 so as not to output the video data from the processing device 10 to an external device via the communication unit 140 and other video output units.

According to the embodiment described above, when the processing device 10 performs the initialization process of the memory card 250, it is recorded in the memory card 250 during the period from the detection of the attachment of the memory card 250 to the detection of the removal of the memory card 250. Do not play the video. Further, the initialization of the memory card 250 involves an operation setting for making the recording device 30 usable. Therefore, it is possible to prevent the video data recorded on the memory card 250 from leaking to the outside and prevent it from being viewed by the administrator or the like. Therefore, even if the memory card 250 is used for recording the image of the recording device 30 set in a public place such as a train, it is possible to avoid privacy and security problems due to the leakage of the image. ..

Further, even when there are many memory cards 250 to be initialized, the continuous initialization process described above makes the work related to the initialization easier and shorter for the administrator than when there is no memory card 250. be able to.

Furthermore, unlike the method of copying the operation setting information of the memory card of the copy source (master) to the memory card of the copy destination (for example, a newly purchased one), the memory card of the same manufacturer and the same quality at the same time. The requirement that it is desirable to use is relaxed. Therefore, there may be variations in the manufacturing time, the manufacturer, the quality, and the like of the memory card initialized by the processing device 10. In this way, the processing device 10 can perform initialization processing on a plurality of memory cards of different types. Also, the administrator does not have to have a high degree of expertise in the state of the memory card. Further, according to the processing device 10, unlike the case where the master memory card is copied by the duplicator, information and traces in the copy destination memory card such as the number of overwrites can be left, and some problem occurs. It is also possible to analyze when it is done.

[2. Second Embodiment]
The second embodiment will be described. The second embodiment is an embodiment in which a plurality of initialization methods can be selected from, for example, a menu display. The configuration in the second embodiment and the configuration in the first embodiment are basically the same. Hereinafter, the differences between the first embodiment and the second embodiment will be mainly described. Therefore, the same configuration and the same processing are designated by the same reference numerals, and the description thereof will be omitted.

[2.1 Overall overview]
FIG. 8 is a diagram for explaining the overall flow of the present embodiment. The control unit 100 of the present embodiment displays a top screen for allowing the user to select a process. Here, the control unit 100 in the present embodiment first displays the top screen on the display unit 130. Then, the user can select "continuous initialization processing", "complete initialization processing", and "confirmation initialization processing" from the top screen, and the control unit 100 executes the selected processing.

The continuous initialization process executes the first initialization process according to the first embodiment. In addition, the complete initialization process executes the second initialization process (complete initialization process) in the first embodiment. Further, the confirmation initialization process is obtained by adding the confirmation process to the first initialization process.

The processing flow of the present embodiment will be described with reference to FIG. The control unit 100 displays a top screen (F10) on which the user can select each process. Here, when each process is selected, the control unit 100 executes the selected process.

For example, when the continuous confirmation process is selected by the user from the top screen, the control unit 100 executes the continuous initialization process (F12). In the continuous initialization process, the initialization process is repeatedly executed until the user instructs to stop the process or returns to the top screen. The continuous initialization process is the process shown in FIG.

When the confirmation initialization process is selected by the user, the control unit 100 executes the confirmation initialization process (F14). The confirmation initialization process includes an operation of confirming with the user when executing the initialization process. In the confirmation initialization process, the initialization process is repeatedly executed until the user instructs the user to cancel the process or returns to the top screen. The confirmation initialization process is the process shown in FIG.

When the user selects the complete initialization process, the control unit 100 executes the complete initialization process (F16). The complete initialization process executes the second initialization process described above. In the complete initialization process, the control unit 100 shifts the process to the top screen when the user instructs the user to stop the process or returns to the top screen. Further, in the case of the complete initialization process, the control unit 100 once shifts the process to the top screen after the complete initialization is completed. In the complete initialization process, the process may be repeated until the user gives an instruction to return.

[2.2 Processing flow]
FIG. 9 is a diagram illustrating the operation of the confirmation initialization process in the second embodiment. The confirmation initialization process is substantially the same as the process flow described with reference to FIG. 6, the same process is designated by the same reference numerals, and different parts will be mainly described.

When the control unit 100 detects that the memory card 250 is attached, the control unit 100 displays a display based on the information related to the memory card 250 (step S202). The information related to the memory card 250 may be the information included in the memory card information 252 or the information extracted from the video data 234.

Here, various types of information that can be displayed as the memory card information 252 can be considered. For example, as information about the recording device 30, the recording date and time of video data, the model of the recording device 30, the manufacturer, the number of times an event has occurred, and the like are recorded. Further, for example, information such as information on an automobile provided with a recording device 30, an icon, information on a railroad, and an icon indicating a vehicle can be recorded. In addition, the control unit 100 can select and display necessary information from the information recorded in the memory card information 252.

Then, the control unit 100 confirms with the user whether or not the initialization of the memory card 250 may be executed (step S204). When the user instructs that the initialization may be executed, the control unit 100 initializes the memory card 250.

This allows the user to determine what kind of memory card he / she is trying to initialize when he / she is continuously initializing the memory card. The system described in this embodiment can prevent the user from accidentally deleting the data on the memory card, which is necessary.

[2.3 Operation example]
Here, the present embodiment will be described with reference to FIG. In FIG. 10A, the control unit 100 displays the display screen W200 as the top screen. Here, on the display screen W200, a button R202 for executing the continuous initialization process, a button R204 for executing the confirmation format, and a button R206 for executing the complete format (complete initialization process) are displayed on the display screen W200. Is displayed.

Here, as an example, when the button R204 is selected, the control unit 100 executes the confirmation initialization process. When the confirmation initialization processing button R204 is selected by the control unit 100, the display screen transitions to the display screen W210 of FIG. 10B.

Here, when the user installs the memory card, the control unit 100 reads the information from the memory card and displays it on the display unit 130. FIG. 10C is a diagram showing a display screen W220, which is an example in which the control unit 100 displays information on the memory card.

On the display screen W220, as memory card information, the type of memory card, the model name of the recording device 30 that recorded the video data, the date and time when the video data was recorded, and the number of events recorded as event information are displayed in the area R224. ing. The display screen W220 is also called a model confirmation screen.

Here, the event information is the number of times detected as an event when the recording device 30 meets a predetermined condition. For example, the recording device 30 records that the acceleration of a predetermined pattern is detected or the acceleration of the threshold value or more is detected as an event, and the number of times of the event is displayed as event information. In addition, the control unit 100 can display the number of events included in the event information. The control unit 100 can also display the number of times for each type of event.

Further, on the display screen W220, a button R220 for instructing to execute initialization and a button R222 for instructing to stop processing (instructing to return to the top screen) are displayed. Here, when the button R220 is selected by the user, the control unit 100 executes the initialization process. Then, when the memory card 250 is initialized, the control unit 100 displays on the display screen W230 that the initialization is completed (finished).

Further, when the event information is not recorded or there is no memory card information to be displayed, it may be displayed that there is no event information, or FIG. 10C may be simply hidden. That is, when there is event information, the control unit 100 displays a confirmation display screen for the user to confirm, but if there is no event information, initialization may be performed as it is.

The control unit 100 may display not only the information recorded in the memory card but also the corresponding information as the information of the memory card. For example, FIG. 10E is an example of a display screen W240 displaying information on the memory card 250. Here, the memory card 250 records the place where the recording device 30 is provided (for example, No. 001 on the A line) as one of the card information.

Therefore, the control unit 100 acquires the railway icon corresponding to the card information from the storage unit 110 or the external server and displays it in the area R240. In this way, the control unit 100 can provide a display screen that is easier to understand by visualizing the information based on the card information.

Further, FIG. 11 is an example of a display screen when the control unit 100 executes the complete initialization process when the button R206 is selected by the user in FIG. 10A.

FIG. 11A is an example of the display screen W250 displayed in the execution of the complete initialization process. The control unit 100 displays on the display screen W250 as an alert that it takes time for complete initialization. The control unit 100 may also display the processing time expected by the complete initialization.

When the button indicating "OK" is selected by the user on the display screen W250 of FIG. 11 (a), the transition to the display screen W260 of FIG. 11 (b) is performed. The display screen W260 of FIG. 11B is the same as the display screen W100 of FIG. 7A.

Subsequently, when the control unit 100 detects that the memory card 250 is installed, it executes complete initialization. The control unit 100 may display the display screen W270 as shown in FIG. 11C while performing the complete initialization of the memory card 250.

The display screen W270 includes a message "Complete FORMAT in progress" as the current processing content. The control unit 100 does not display a message in the continuous initialization process or the confirmation initialization process because the execution time is short. However, the control unit 100 displays a message because the execution time is long in the complete initialization process.

The control unit 100 may display a progress bar for displaying the progress of processing on the display screen W270, or display a progress such as "XX% finished".

Then, when the complete initialization process is completed, the control unit 100 displays the display screen W280 of FIG. 11D and ends the process. In the present embodiment, when the complete initialization process is completed, the screen returns to the top screen once, but it may be continuously executed.

As described above, according to the present embodiment, the user can select and execute the initialization process according to the desired method. Further, the control unit 100 can output an alert in the case of a memory card in which an event is recorded. As a result, the user can initialize the memory card, which is more convenient and highly secure.

[3. Third Embodiment]
The third embodiment will be described. The third embodiment is an embodiment in which a warning screen is displayed in consideration of a case where the memory card is already installed when the top screen is displayed and the memory card is forgotten to be removed. The configuration in the third embodiment and the configuration in the second embodiment are basically the same. Hereinafter, the differences between the second embodiment and the third embodiment will be mainly described. Therefore, the same configuration and the same processing are designated by the same reference numerals, and the description thereof will be omitted.

[3.1 Processing flow]
FIG. 12 is a diagram showing a flow of processing executed by the control unit 100 in the present embodiment. The control unit 100 executes the process of FIG. 12 before displaying the top screen. Further, the trigger for operating the program for executing the process of FIG. 12 may be the same as that of the first embodiment described above. The control unit 100 does not reproduce the video recorded on the memory card 250 during the period of executing the process of FIG.

First, the control unit 100 detects whether or not a memory card is already installed (S302). Here, if the memory card 250 is already installed at the stage of activating the top screen, the control unit 100 displays a warning screen on the display unit 130 (step S302; Yes → step S304). In addition to the warning screen, the control unit 100 may be notified by a sound or an alert.

Then, when the control unit 100 detects the removal of the memory card 250 (step S306; Yes), the control unit 100 displays the top screen (step S308). Further, the control unit 100 displays the top screen even when the installation of the memory card is not detected for the first time (step S302; No → step S308).

Then, the control unit 100 executes the selected initialization process (step S310). That is, any one of continuous initialization processing, confirmation initialization processing, and complete initialization processing is executed. Further, the user can repeatedly execute the initialization process until the present process is completed (step S312; No → step S310).

When the user instructs the end of the process (step S312; Yes), the control unit 100 ends the process.

[3.2 Operation example]
FIG. 13 is an example of a display screen displayed on the display unit 130 for explaining an operation example in the present embodiment. FIG. 13A is an example of the display screen W300 displayed on the display unit 130 when the memory card 250 is already installed when the control unit 100 executes the process.

On the display screen W300, the message "Please remove the memory card once!" Is displayed. Therefore, the user cannot proceed as a process unless the memory card 250 is removed from the card reader.

Further, the control unit 100 may display a screen for selecting whether or not to continue the process, as in the display screen W310 of FIG. 13B. In this case, if the user selects to continue the process, the control unit 100 displays the top screen as it is. Further, when cancellation is selected by the user, the control unit 100 may display the display screen W300, or may perform a process of not displaying the top screen unless the memory card 250 is removed.

Although it has been described in FIG. 12 that the control unit 100 displays the top screen after displaying the warning screen, the top screen may be displayed first. For example, in FIG. 13B, the top screen is displayed as the display screen W315. In this case, for example, the display screen W300, which is a warning screen, may be superimposed or displayed on the display screen W315, which is the top screen, or may be switched and displayed.

Although the display screen W310 is displayed superimposed on the display screen W315 which is the top screen, it may be displayed integrally with the display screen W315 which is the top screen. For example, the control unit 100 may display "a memory card is already inserted" by using a part of the area of the top screen.

Further, the control unit 100 may display information about the memory card 250 as shown in the display screen W320 of FIG. 13C. After confirming the displayed information of the memory card 250, the user can select whether to continue the process or remove the memory card 250.

According to the present embodiment, if the memory card is still installed at the time of starting the process, the control unit 100 displays an error and cancels the process. Although the above-described embodiment has been described at the time of initial startup, for example, when the memory card is still installed (for example, 30 minutes and 1 hour) even after a predetermined time has elapsed, the warning display is similarly applied. You may.

[4. Fourth Embodiment]
A fourth embodiment will be described. A fourth embodiment is an embodiment in which, in the initialization process, when the installed memory card matches a specific condition, a process of asking the user whether the memory card may be initialized is performed. In principle, the configuration in the fourth embodiment and the configuration in the first embodiment are the same. Hereinafter, the differences between the fourth embodiment and the first embodiment will be mainly described. Therefore, the same configuration and the same processing are designated by the same reference numerals, and the description thereof will be omitted.

The process of FIG. 14 replaces the process of FIG. 6 of the first embodiment. Hereinafter, the processes common to FIGS. 14 and 6 are designated by a common reference numeral, and detailed description thereof will be omitted.

When the installation of the memory card is detected (step S102 → step S104; Yes), the control unit 100 determines whether or not the memory card 250 matches the specific condition (step S402). Then, when the memory card matches the specific condition, the control unit 100 confirms whether the memory card may be initialized by the user (step S402; Yes → step S404).

Then, the transition to step S106 occurs only when the user performs an operation for performing initialization (an operation for continuing the initialization process), that is, when it is determined that the execution of the initialization process is OK (step S404; Yes → step). S106). As a result, when the specific conditions are met, the control unit 100 does not automatically initialize the memory card, but once confirms with the user. Then, when the user performs an operation that may be initialized, the memory card is initialized (step S404; Yes → step S106 to step S112).

Here, the specific condition may be a predetermined condition, or a condition selected or set by the user. For example, the following selection conditions can be considered.

(1) Whether the format method of the memory card 250 is a specific format method or not, or whether the format method of the memory card 250 is a specific format method or other is a specific condition. Here, the specific format method may refer to a format method supported by the recording device 30 (processing device 10) or a format method desired by the user among the supported format methods. Then, as a specific condition, when the format method of the memory card 250 is other than the specific format, it is confirmed to the user whether to perform the initialization process as it is. For example, the control unit 100 displays to the user that the specific format method is not used (for example, the display screen W400 in FIG. 15A).

Further, when the specific format method is, for example, the above-mentioned first format method, the initialization unit 102 and the complete initialization unit 104 store the first format method as the specific format method. Then, the initialization unit 102 and the complete initialization unit 104 select the first format as the default format method.

Further, it may be determined from the nature of continuous memory cards. For example, it may be determined whether or not the format method is the same as that of the memory card formatted immediately before. In this case, if only the first person makes a mistake, the same format method can be continuously used.

Further, when the initialization button is selected by the user on the display screen W400 of FIG. 15, the control unit 100 continues the process. In this case, the control unit 100 may execute the complete initialization process.

(2) The elapsed time from the previous initialization is set as a specific condition The elapsed time from the last initialization of the memory card 250 to the current time is set as a specific condition. For example, it is assumed that the video data recorded on the memory card needs to be stored for a predetermined period for security. If this predetermined period is set to, for example, one week, the control unit 100 displays a message if one week has not passed since the memory card 250 was last initialized (for example, the display screen W410 in FIG. 15B). ).

(3) When it depends on the recorded contents Whether or not an event is recorded on the memory card 250 and the number of recorded events are set as specific conditions. For example, when an event is recorded in the memory card 250, the control unit 100 can display the fact and let the user select the initialization method.

Further, the control unit 100 displays a message indicating that an event is recorded on the memory card 250 (for example, the display screen W420 of FIG. 15C).

Here, on the display screen of FIG. 15C, the control unit 100 displays the information of the normal initialization button (R420) and the memory card 250 as the initialization method, and then performs the initialization. The button (R422) is displayed. When the control unit 100 executes the process corresponding to the button selected by the user, an appropriate initialization process can be executed.

(4) When selecting complete initialization The elapsed time from the last complete initialization of the memory card 250 to the current time is set as a specific condition. For example, the control unit 100 displays on the display screen W430 of FIG. 15D that three months have passed since the memory card 250 was completely initialized. In this case, on the display screen W430, the control unit 100 displays a button (R430) for performing normal initialization and a button (R432) for performing complete initialization. The control unit 100 executes processing according to a button selected by the user. Therefore, the user can select and execute two initialization methods.

In the present embodiment, when the installed memory card 250 matches the specific conditions, the process of asking the user whether the memory card may be initialized has been described, but other processes may be performed. .. For example, when the installed memory card matches a specific condition, it may be rejected as an error. That is, when the specific conditions are met, the memory card 250 is not initialized, and a more secure system can be provided.

[5. Fifth Embodiment]
A fifth embodiment will be described. The fifth embodiment is an embodiment in the case where a plurality of memory card readers (recording units) are provided, for example, as in the processing device 20 shown in FIG. 1 (b). The configuration in the fifth embodiment and the configuration in the first embodiment are basically the same. Further, the configuration of the processing device 20 will be described as the same configuration except that a plurality of card slots into which memory cards can be mounted are provided.

The processing device 20 stores the management table 116 shown in FIG. 16 in the storage unit 110. The management table stores the slot number (slot number) in which the memory card can be installed, the detection state, and the initialization state.

The detection state indicates whether or not the memory card 250 is installed in the slot. A memory card 250 is installed in the slot whose detection status is “◯”. Further, the initialization state stores whether or not the memory card 250 has been initialized. That is, when the memory card 250 is installed in the recording unit 150 (card slot), the control unit 100 changes the detection state from “−” to “◯”. In addition, the initialization state is "uninitialized".

Here, when the control unit 100 initializes the memory card 250, the initialization state changes from "uninitialized" to "initialized".

As a result, the processing device 20 can grasp which slot of the plurality of slots the memory card 250 is installed in. In addition, it is possible to manage whether the installed slot card is "initialized" or "unprocessed".

Further, the control unit 100 initializes the memory card 250 installed in the slot whose detection state is “◯” and whose initial state or state is “uninitialized”. As a result, the memory card can be continuously and efficiently initialized.

In this case, it may be realized in combination with the above-described embodiment within a reasonable range. For example, the control unit 100 displays a warning screen when there is a memory card in which event information is recorded while the memory card is being continuously initialized. At this time, the control unit 100 may display the corresponding slot number together with the memory card information 252 and the information based on the event information on the warning screen. Further, the control unit 100 may provide an LED next to the slot in which the problem is occurring, and illuminate / blink the LED to prompt the user for confirmation.

[6. 6th Embodiment]
The sixth embodiment will be described. The sixth embodiment refers to the history information stored in the history data 114 and outputs a report. In principle, the configuration in the sixth embodiment and the configuration and processing in the first embodiment are the same. Further, the content of the sixth embodiment can be implemented in combination with the above-described embodiment.

FIG. 17A is a diagram showing an example of the data structure of the history data 114. The history data 114 includes the date and time when the initialization was executed on the memory card 250 (for example, "2019/12/15 11:45:16") and the identification information for identifying the memory card (for example, "125F5485"). , The processing content executed as initialization (for example, "initialization") is stored in association with each other.

Further, although not shown, other data may be stored in the history data 114. For example, the information of the executor when the initialization process is executed may be specified from the user information 112 and further stored. By storing the information of the executor together, the administrator can grasp who executed the initialization and when.

Further, the control unit 100 may be able to specify the information about the event recorded in the memory card 250, the recording date and time of the video data, and the like from the identification information. Information about the event, information about the recording date and time of the video data, and the like may be stored together with the history data 114, or may be stored as a separate table.

FIG. 17B is an example in which the control unit 100 actually outputs a security report based on the historical data 114. The control unit 100 may send a security report by e-mail or output it to a screen. Alternatively, the printing device may print on paper.
