At the time when the POWER switch 14a is turned on, the external I / F is set in a receivable state by the interrupt processing of the system controller 10 from the PC. Therefore, to enter the communication state with the modem, use MODEM
The switch 14e is turned on.

FIG. 8 is a diagram showing a display state of the display unit 13 when the modem 23 is connected and designated. The data transfer procedure using the modem 23 of the DSC 20 will be described with reference to FIG. To do. First, as shown in FIG. 8A, when the modem 23 is selected and connected and the communication becomes possible, the segment "CONNECT" blinks.
So, start communication, but first, in the modem,
Using the built-in AT command, the telephone number of the other party stored in advance in the system controller 10 is called, and the carrier is transmitted by activating the transmission request signal “RS” shown in Table 4. And Table 4
The carrier is detected from the other party by the carrier detection signal "CD" shown in FIG. For confirmation of the other party, the signal "CA
MERA "is transmitted. When the confirmation signal “ACK” from the PC 26 side of the communication destination is received, as shown in FIG. 8B, it is determined that the connection is completed, and “CONNECT” on the display unit is displayed.
"T" is turned on and, for example, the frame number "01" of the transfer image data is displayed.

If the above connection is not completed within a certain period of time, for example, one minute, as shown in FIG.
The error message "r" is displayed, the power is turned off once, and the operation is retried. Further, each display described above can be displayed on the monitor 21. When the connection is completed, the UP switches 14c, D
The OWN switch 14d is operated to select the frame number, and the image to be transmitted is displayed on the monitor 21. When the trigger switch 19 is pressed, the image data is transmitted. This image data is transmitted by first transmitting the file size and then transmitting the image file as binary data. Upon receiving the received data of the file size, the PC 26 on the receiving side stores it as a file in the medium. In addition,
The "AT command" is generally used to control the modem as described above. Also, the modem can be controlled by using the CCITT standard.

Next, each control processing operation of the DSC 20 will be described in more detail with reference to a flowchart. Figure 9
6 is a flowchart of a subroutine "reception interrupt process". The DSC 20 turns on the RS23 when the power is turned on.
2C I / F 15 is set to P by the system controller 10.
It is set to be able to communicate with C. After that, the MODEM switch 14e is operated to set the modem mode. In this state, when the transmission signal from the modem 24 is received, the system controller 10 executes an interrupt process to capture the reception signal from the modem 24.

That is, in the flowchart of FIG. 9, it is checked in step S1 whether or not the modem mode is currently set. If it is not the modem mode but the PC mode, the process proceeds to step S2 and the process corresponding to the command of the PC is performed. In the modem mode, the received data is stored in the modem control puffer in the system controller 10. The processing of this data is executed by the modem processing subroutine.

FIG. 10 is a flow chart of the subroutine "trigger switch process" when the trigger switch 19 is operated. In this process, in step S5, it is checked whether the modem mode is currently set. If the mode is not the modem mode, the process proceeds to step S6, and it is further checked whether the mode is the recording mode. If it is not in the recording mode, this routine is finished as it is. If it is the recording mode, the process proceeds to step S7 to perform the photographing process. If it is determined in step S5 that the mode is the modem mode, the process proceeds to step S8. Then, the file size of the image data to be transmitted is transmitted, the image data is transmitted in step S9, and this routine ends.

FIG. 11 is a flowchart of the subroutine "modem switch process" which is called when the modem switch 14e is operated. In step S11, it is checked whether or not it is currently in the modem mode. If it is in the modem mode, the process jumps to step S13 to call a subroutine "modem mode release process" which will be described later. If the mode is not the modem mode, the process proceeds to step S12 and the mode is set to the modem mode in which the modem communication is possible. In this process, the mode is set by setting the flag indicating the modem mode to "1". Then, in step S14, the display unit 13 blinks the "CONNECT" display. Step S15,
The modem is recognized and set at 16. This process is performed by DSC
When it is confirmed that the signal "ER" in Table 4 is output from the 20 side and the active signal of the signal "DR" is returned from the modem side, the process proceeds to step S17. If the above confirmation is not made, the process proceeds to step S22, an error is displayed, and this routine ends.

In step S17, line connection processing is performed by the AT command. This process outputs the signal "RS" to the modem and causes the modem 23 to output the carrier. When the signal "CS" shown in Table 4 above is detected and further the signal "CD" which is the carrier detection signal from the modem is detected and it is confirmed in step S18 that the line connection is completed, step S19 is performed. Proceed to. If the completion of the connection is not confirmed, the process proceeds to step S22,
An error is displayed and this routine ends.

In steps S19 and S20, a signal "CAMERA" is transmitted to confirm the other party, and it is checked whether the confirmation signal "ACK" from the communication destination can be received. When the signal "ACK" is received, "CONNECT" is lighted on the display unit 13 and this routine is finished. However, if the confirmation signal “ACK” from the communication destination cannot be received within the fixed time, step S22.
Jump to and display the error.

FIG. 12 is a flowchart of the subroutine "modem mode release processing" called in step S13. The modem mode is cleared in step S31 of this routine, and the signal "COM-END" is transmitted to the other party in step S32. The other party stops transmission of the carrier signal for signal transmission by the signal "COM-END". When the stop of the carrier is detected in step S33, an AT command is sent to perform line off processing. Then, in step S34, the signal "ER" sent to the modem is turned off, and the modem control ends. Further, in step S35, the display unit 3 is set to display during normal recording or reproduction processing, and this routine ends.

As described above, in the present DSC 20, a modem or a PC connected to the connector 16 which is a single connecting part connected to one external I / F.
It is possible to perform information communication by recognizing the type of each of the above by the system controller 10 and causing the interface of the device mode to function. Therefore, it is possible to provide a highly functionalized device that enables information communication with a plurality of external devices and has a downsized main body.

The DSC 20 is provided with a connector 16 which is one connection portion with an external device, and switching of communication between a PC and a modem is performed by operating a modem switch 14e. However, as a modification thereof, it is possible to propose a modification in which a switch operating portion 31a for operating the mode changeover switch is provided above the receiving side connector 31 as shown in FIG. A protrusion 32a for pressing the switch operation 31a is provided on the connector 32 of the modem which is one external device applied to this modification, and the switch operation 31a is attached to the connector 33 of the PC which is the second external device. No pressing protrusion is provided.

When the modem connector 32 is connected, the mode changeover switch operating section 31a is turned on to automatically switch to the modem mode. When the PC is connected to the connector 32, the mode is changed. The changeover switch is turned off to switch to the PC mode. As described above, in the present modification, the mode can be switched without performing the manual switching operation.

As another modification, a mode specifying signal line for the PC and the modem is provided in the signal line of the connector to the external device, and when any device is connected, the voltage level of the specifying signal line is set. The mode of the communication device can be selected by detecting the. In the above example, since the normal state after the power is turned on is the PC communication mode, by connecting the remote control unit or the like to the connector 16 of FIG. 1 in that state, the remote control operation is performed by the I / F in the PC communication mode. Is possible. FIG. 14 shows the remote control unit 35.
The connector 35b is inserted into the connector 16 of the DSC 20, and remote control control is possible in this state.

FIG. 15 shows a memory card 1 which is a recording medium.
It is a figure which shows arrangement | positioning of 7 data. The data area is J
As proposed by EIDA (Japan Electronic Industry Development Association), it is composed of an attribute memory for recording attribute information that gives basic card compatibility information and a common memory for recording image information. Card compatibility information is recorded in the attribute information area at the head of the common memory. Next, in the boot sector area, the OS (operating system) of the I / F of the DSC 20 is DOS.
FAT (FILE ALLO, which will be described later, by using
CATION TABLE), and management area information of the root directory (hierarchical structure) is recorded. Furthermore, the above FA
Data recording area information is recorded in a chain format in the T area, and information about how the data is recorded in a data recording area, which will be described later, is recorded in the root directory area.

The data recording area that is provided next is composed of each image file. Data relating to one frame of image is written in each image file. As shown in FIG. 16, the image file is
It is composed of a header and image data, and a specification tuple, a data format tuple, a photographing information tuple, a comment tuple, etc. are recorded in the header. The above specification tuple is the specification version, the type indicating the video / audio / control of the file,
Gives the size of the header. The data format tuple gives the format of the file main body, that is, JPEG, non-compressed, PICT, and other format for holding image data. In the comment tuple, a description of shooting and the like are recorded. DS of this example
C20 is characterized in that this comment tuple can be rewritten.

In the image file recording area, in addition to the image data file, an audio file in which audio information corresponding to an image of the image data is recorded, and correspondence information between the image file and the audio file corresponding to each other. A control file that stores is also stored. In this control file, all data is recorded in tuple format.
Further, a subdirectory entry is also stored in the image file recording area.

FIG. 17 is a diagram showing the data structure of the tuple format, and the tuple I is a tuple I representing prescribed data.
D, a pointer of the next tuple, and tuple data. As shown in FIG. 18, the photographing information tuple includes a photographing information ID, a next tuple pointer, date data, aperture data, shutter speed data, white balance setting data, focus position data, and zoom position. It is composed of data and strobe data.

As shown in FIG. 19, the comment tuple is composed of a comment ID, a next tuple pointer (final code), a comment data length, and comment data. A large area is secured. Further, as shown in FIG. 20, the control file includes a specification tuple, a comment tuple of a directory in which the file is stored, a reproduction sequence tuple that is reproduction order information, and related information of an image file and a corresponding audio file. It consists of file-related tuples and The control file is stored in the same directory area as the image file, but can be stored in a subdirectory.

The DSC 20 receives various commands from an external device such as a PC and performs respective control operations. The commands received from the PC and the functions thereof are shown in Table 5 below. . Each of these commands is transmitted to the DSC 20 by a transmission signal based on hexadecimal numerical data, for example.

[0045]

[Table 5]

Next, a description will be given of processing operations such as reference, writing, and additional writing of comment data by the DSC 20. For the description of this operation, the PC 22 is connected to the DSC 20 as shown in FIG. 3, and a comment stored in the header of the image file of the memory card 17 is written and added according to an instruction from the PC side. A case of performing the operation will be described as an example.

First, the PC 22 takes in the directory information of the image file of the memory card 17, and the file name is displayed on the monitor of the PC 22 as shown in FIG. Therefore, the file No. shown in the figure is used to select the file in which the comment is written. To choose from. If NO. When 1 is specified, the corresponding file DSC as shown in FIG.
00001. The shooting data of J61 and the current comment are displayed. At this time, the DSC 20 side is connected to the monitor 21.
The photographed data and the current comment are also displayed in (FIG. 3). In addition, when a memory card without a comment area is used, an inquiry is made as to whether to create the area.

Therefore, when the PC 22 issues a comment writing command shown in Table 5 and inputs a comment, new comment data is overwritten in the comment area in the header. FIG. 23 shows the overwritten state. If the input comment data capacity is larger than the reserved comment area, a warning is issued, and if the area can be expanded, the area is expanded.

When shooting by remote control from the PC 22, the shooting data is set from the PC 22 side.
It is possible to instruct the timing of shooting and write a comment immediately after shooting from the PC 22 side. The comment reference / change operation will be described with reference to the flowchart of the subroutine “comment reference / change processing” in FIG.

In steps S40 and S41, the directory information of the image file in the memory card 17 is set in the PC 22.
Received and displays the directory information. Step S
At 42, the file number for changing the comment is input. The display at this point is shown in FIG. In step S43, the file corresponding to the input file number is designated. Then, in steps S44 and 45, the shooting data and comment data of the file are received, and in step S46, the shooting data and comment data are displayed.
The display at this point is shown in FIG. Step S47
Enter comments to add / change. In step S48, it is checked whether the comment has been changed. When there is no change, this routine is ended as it is, but when it is changed, a comment is written and this routine is ended.

Next, the operation of shooting with comments will be described with reference to the flowchart of the subroutine "shooting with comments" in FIG. In this shooting operation, when shooting by remote control from the PC 22, a comment is specified after the shooting data is specified, and then,
The PC 22 gives a shooting instruction. Immediately after that, the comment is written.

That is, in steps S51 and S52, shooting data is input and shooting data is set. A comment is input in step S53, and it is checked in step S54 whether or not a shooting instruction is input. If there is a shooting instruction, the process proceeds to step S55 and shooting is performed. Further, in step S56, a comment regarding the screen photographed immediately before is written, the status signal is read from the DSC 20 in step S57, the process proceeds to step S58, and the image-capable state of the DSC 20 is checked. Step S55
If the photographing is not possible, this routine is finished.

Next, the command processing operations 2 and 3 used in the communication between the PC and the DSC shown in Table 5 will be described in detail. First, the directory transmission command processing will be described. FIG. 26 shows the PC 22 and the DSC 20.
7 is a time chart of a directory transmission command of and, and transmission of directory data. PC20 to D
A command signal and a directory designation signal, which are 1-byte signals, are transmitted to the SC 22 in accordance with the RS232C standard. In the directory designation signal, 0 indicates the root directory, and other than 0 indicates the subdirectory of the directory entry at the designated position. And DSC2
0 receives the signal and performs interrupt processing to
The maximum number K of bytes of directory data and the directory data are transmitted.

FIG. 27 shows the structure of the root directory. Entry 0 that constitutes the root directory,
1, 2, 3 ... are the frame numbers. Will correspond to the image file in the data area. However, when a subdirectory is created, the corresponding entry becomes the directory entry for the subdirectory. Then, the sub-directory data is stored in the data area. However, the entry 0 of the subdirectory has the file name "." And its own position information is stored, and the entry 1 has the file name ".." and the position information of the upper directory. Then, the directory data is stored after the entry 2.

FIG. 28 shows the format of a directory entry composed of 32 bytes. Table 6 is a table showing attribute values and attribute contents.

[0056]

[Table 6]

Next, the comment transmission will be described. FIG. 29 is a time chart of the comment transmission command between the PC 22 and the DSC 20 and the comment data transmission. A command signal, which is a 1-byte signal, is transmitted from the PC to the DSC in accordance with the RS232C standard. DSC
Receives the signal and executes the interrupt process to transmit the byte number data of the comment data and the comment data to the PC. These processes are executed after the file specification command.

FIG. 30 is a flow chart of the subroutine "comment transmission command processing" of the comment transmission operation. In step S61, the bus 12 is set for memory card access. The start address of the file designated in step S62 is calculated by the start cluster of the directory. In step S63, the comment tuple is searched, and in step S64, the presence or absence of the comment tuple is checked. As described above, when the comment tuple is not provided on the card due to the recording specifications of the memory card, the process jumps to step S68 and the signal "NA" is sent to notify the PC 22 side that the comment tuple is not provided.
"K" is transmitted, and the process proceeds to step S67. After that, create a comment tuple and make the comment writable,
The comment transmission process will be executed again.

On the other hand, when the comment tuple can be detected,
It proceeds to step S65. In step S65, the byte number data of the comment tuple is transmitted. Then, the comment data is transmitted in step S66. afterwards,
In step S67, the bus 12 is released and this routine ends. Next, the comment writing operation will be described. FIG. 31 is a time chart of the comment write command between the PC 22 and the DSC 20 and the transmission of the write comment data. That is, from PC22 to DSC
A command signal, a byte number data signal, and a write signal are transmitted to 20 in accordance with the RS232C standard. DSC2
0 receives the signal and writes the comment data by interrupt processing. In this case, DSC20
There is no transmission from PC to PC22.

FIG. 32 is a flowchart of the subroutine "comment writing command processing" of the above command writing operation. A byte number data signal is received in step S71, and the bus 12 is set for memory card access in step S72. In step S73, the start address of the designated file is calculated by the start cluster of the directory. In step S74, a comment tuple is searched, and in step S75, the presence or absence of the comment tuple is checked. If no comment tuple is provided in the memory card, the process jumps to step S80. If the comment tuple is already provided, the process proceeds to step S76.

In step S76, it is checked whether or not the number of bytes of the comment tuple currently prepared is the number of writable bytes. If you run out of bytes,
The process jumps to step S79 to transmit the write-disabled signal "NAK" to the PC 22, and proceeds to step S78. On the other hand, if the number of bytes is not insufficient, step S
In step 77, the received tuple data is sequentially overwritten on the comment data. Then, in step S78, the bus 12
Is released and this routine ends.

If the process jumps to step S80, a comment tuple is generated at the end of the tuple, the size of the generated tuple area is checked in step S81, and the generated tuple area is large enough to write comment data. If so, jump to step S77. When the size of the area is insufficient, the process proceeds to step S82, the signal "NAK" is transmitted to the PC 22 side, and the process proceeds to step S78. If the generated comment tuple area is sufficient, the process proceeds to step S77 and step S77.
At 78, the bus 12 is released, and this routine ends.

In this DSC 20, the external I

Change processing of the hierarchical data structure management area 7 is performed. The operation of changing the directory which is the management area by the operation of the PC 22 side connected to the DSC 20 will be described below. FIG. 33 is a menu screen of the PC 22 at the time of change processing. For example, when creating a subdirectory,
Key NO. Select 1. The screen display is that shown in FIG. Therefore, a comment associated with the generation of the subdirectory is input by the key of the PC 22 and "Y" is input by the key operation to generate the subdirectory.

Further, in the menu screen display state of FIG. 33, the key NO. When the file move of No. 2 is selected, the file name and the subdirectory name are displayed on the display screen as shown in FIG.
At this point in time, as shown in FIG. 35, DSC00001. J6I and DSC0
0003. J6I is recorded, there is <SDIR02> as a subdirectory, and DSC02001. J6I
Is stored. Therefore, for example, by inputting "1" by key operation, the image file DSC00001. J
Give instructions to move 6I. Then, as shown in the display of FIG. 36, the process enters a state of waiting for input of the file transfer destination.

When "2" is input as the destination of the file by key operation, as shown in FIG. 37, the image file DSC00001. J6I is a subdirectory <S
DIR02>. If the destination is the root directory, enter "R" as the key input.
Will be entered. The operation of the PC 22 side in the sub-directory creation processing will be described with reference to the flowchart of the subroutine "sub-directory" in FIG. Send to. Step S
A comment is written in 93, the sub-directory is displayed in step S94, and this routine ends.

The operation of the PC 22 side in the file moving process will be described with reference to the flowchart of the subroutine "file moving" in FIG. 39. First, step S1.
The directory is displayed at 01, and the file to be moved is designated and input at step S102. Step S103
Enter the destination directory with. Step S10
In step 4, the directory move command is transmitted to the DSC 20. The new directory that has been moved is received in step S105, the new directory is displayed in step S106, and this routine ends.

Next, the process on the DSC side for creating a subdirectory will be described in detail. 40 shows the PC 22 and D
7 is a time chart of a communication signal at the time of creating a subdirectory between the SCs 20, and the PC 22 sends a subdirectory generation command to the DSC 20. The DSC side searches the earliest free directory in the directory and creates a subdirectory there.

FIG. 41 is a flow chart of a subroutine of the subdirectory generation command processing. In step S111, the bus 12 is set for memory card access. In step S112, a free entry in the directory is searched. Then, in step S113, the presence / absence of the empty entry is checked. If there is no empty entry, the process jumps to step S119 to send a signal “NAK” to the PC 22, and proceeds to step S118 described later. If there is an empty entry, the process proceeds to step S114 to search an empty area having the size of the directory. If there is no space, the process proceeds to step S119. If there is a space, the process proceeds to step S116 to register the subdirectory. In step S117, the control file is registered in the sub-directory, the process proceeds to step S118, the bus 12 is released, and this routine ends.

Next, the processing on the DSC side of the file moving operation will be described in detail. 42 shows the PC 22 and DSC
7 is a time chart of a communication signal at the time of moving a file between 20. A file moving command is transmitted from the PC to the DSC, moving file data, and further moving destination directory data are transmitted. It should be noted that the move file data is 2-byte data up to the subdirectory, and the move destination directory data is 1-byte data because it is only the root directory. The DSC 20 imports these data and registers the migration file in the migration destination directory.

FIG. 43 is a flow chart of a subroutine of the file moving process. In this routine, first, the move file data is received in step S121, and the move destination directory data is received in step S122. In step S123, the bus 12 is set for card access. Then, the directory entry of the move file is read. In step S125, an empty entry in the destination directory is searched for, and in step S12
In step 6, the presence / absence of a free entry is checked. If there is no free entry, the process jumps to step S132, and the
"K" is transmitted, and the process proceeds to step S131 described later.

If there is a free entry, step S12
Proceed to 7 and check for duplicate file names. When duplication is confirmed in step S128, the above step S13
Jump to 2, but if they do not overlap, step S
In step 129, the data of the entry read in the empty entry is read. Then, the erase mark is written in the original entry in step S130, the bus 12 is opened in step S131, and this routine is ended.

Note that the DSC 20 can execute not only generation of a subdirectory and file movement, but also processing such as file name change and file deletion as a built-in function inside the camera. In the DSC 20 of the embodiment of the present invention, the ERASE switch 14f which is the specific operation unit is used.
And a system controller 10 which also serves as a recognition means for recognizing it and a part of a reproduction means. The one-touch playback operation of the shooting screen will be described below. In this one-touch reproduction, when the ERASE switch 14f is pressed after photographing, the screen photographed immediately before is reproduced. Of course, other than the ERASE switch, the screen may be reproduced in response to the driving of a specific operation unit that is not normally used during shooting. Such a specific operation unit is predetermined.

FIG. 44 is a flow chart of the subroutine "trigger switch process" of the photographing processing operation by the trigger switch operation by the DSC 20. Step S141
In step 1, it is checked whether the write protection of the memory card attached to the DSC has been released, whether there is enough free space for recording the image data, and whether the applicable format is available. If it is determined that recording is not possible, the process jumps to step S150 to perform a warning process. If it is determined that the image can be recorded, the process proceeds to step S142, and a shooting process such as capturing image data is executed. Then, in step S143, the image data is compressed and recorded in the memory card 17.

In step S144, the recording frame number. Are saved in the RAM of the system controller 10. In step S145, header data such as shooting time and shooting data is written in the header file. In step S146, the FAT of the memory card 17 and the data in the directory are closed according to the recording state, and the file is closed. Then, the process proceeds to steps S147 and 148. Therefore,
Search subsequent directories and F for next shooting record
Perform an AT search. Then, in step S149, it is checked whether or not a recordable memory area remains in the memory card 17, and if recording is not possible, the process jumps to step S151 to display the card full. If recording is possible, this routine is finished as it is.

Next, the operation of reproducing the image photographed and recorded immediately before when the ERASE switch 14f is pressed will be described with reference to the flowchart of the subroutine "ERASE switch processing" in FIG. In step S161, it is determined whether or not the recording mode is currently set. If it is not the recording mode, the process directly returns. If it is the recording mode, it is checked in step S162 whether it has been recorded, and this check is made in step S of FIG.
144 recording frame No. It is checked whether or not the evacuation process has been performed. Then, if it is recorded, the process proceeds to step S163, and if not recorded, step S16.
The process jumps to step 8 to perform a mute process for changing the screen to a black or blue screen, and the process proceeds to step S166 described later.

In step S163, the frame No. stored in step S144 in the photographing process of FIG. Is read out, and in step S164, the reproduction frame No. To set. In step S165, the frame No. , No. of specified frame with recording date etc. Play the corresponding image. And
The process proceeds to step S166, waits for the ERASE switch 14f to be turned off, and the process proceeds to step S167.
In step S167, the image pickup screen captured through the taking lens is displayed, and this routine is ended.

It should be noted that in the processing of FIG. Memorize ERASE switch 14f and UP switch 14c,
Alternatively, by additionally using the DOWN switch 14d, it is possible to further reproduce the recording screen imaged before that. Next, the operation of erasing all the recorded data of the memory card in the DSC 20 will be described.
This all erase operation has a mode in which a memory check is performed and a mode in which no memory check is performed during the erase.

Conventionally, in an electronic still camera using a memory card, a magneto-optical disk, or a floppy disk as a recording medium, for example, before recording image data on the memory card, initialization, that is, the memory of the memory card is performed. A check and management data writing process and an all erasing process for erasing all recorded data were required.

Then, in order to improve the operability of the camera, the all-erasing operation and the initialization operation are processed as one continuous operation. However, a long time is required for the memory check of the initialization operation. Therefore, a long waiting time is required every time the entire erasing process is performed. In addition, it is naturally conceivable that the previous format may be retained even when the entire deletion is performed, which is inconvenient.

In the all erasing process by the DSC 20, the necessary operations of initialization and all erasing can be performed by a simple operation, and moreover, the initialization format can be designated by the user. Attribute information in the tuple format shown in FIG. 17 is recorded in the attribute memory in the data arrangement of the memory card 17 shown in FIG. 15 or the common memory. Tables 7 and 8 show the tuple ID 9 is a table showing its abbreviations and their meanings.
The tuple ID and the like are based on "IC memory card guideline Ver.4.1" proposed by JEIDA. Further, it is assumed that a basic tuple related to compatibility is arranged in the attribute memory, and a tuple related to compatible data of higher data is arranged in the common memory.

[0081]

[Table 7]

[0082]

[Table 8]

FAT and directory management information is recorded in the boot sector arranged subsequent to the attribute information area of the common memory in the data arrangement of the memory card 17, and Table 9 shows the format of the boot sector. . This format is also based on the "IC memory card guideline Ver.4.1" proposed by JEIDA. In the boot sector, following the jump instruction to the boot code, each manufacturer, etc. in the first part,
In the range shown as BPB, DOS management information, that is, FAT and directory management information as described above is stored. By reading this data, FA
T, the directory can be interpreted. Note that this data has a certain degree of freedom.

[0084]

[Table 9]

FIG. 46 is a diagram showing the structure of the FAT recorded after the boot sector. Each entry of the FAT data recording area is divided corresponding to a cluster. For example, each entry corresponds to 2 clusters, 3 clusters, ... Each entry has a 12-bit configuration. Note that the first two entries 0 and 1 are system reserved. And FA
The data structure of T is a chain structure in which the clusters used are sequentially specified starting with the entry specified by the directory. OFFFH at the end of the chain
(H indicates hexadecimal number) ends with. In addition,
Entry data 0 indicates an unused state.

Next, the all erase operation will be described with reference to the state of the display screen. When the entire erasing operation of the memory card 17 is performed, the management area is checked, and if the known format is performed, only the erasing of the file is performed. If the known format has not been performed, memory check and format are performed.

FIG. 47 shows the display screen of the display unit 13 or the monitor when the total erasure is performed in the state where the unformatted memory card that needs to be formatted is mounted. In this case, the erasing mode described later is “mode A”. In the erase operation, first, the ERASE switch 14
When the all erase preparation mode is set by pressing f and the UP switch 14c multiple times, "A mode" in FIG.
Screen is displayed and the segment “ERASE” blinks. Then, when the trigger switch 19 is pressed, it is confirmed that the memory card is unformatted, and initialization for memory check and formatting is started.

FIGS. 47B and 47C are display screens during the above initialization processing. Since it takes a long time to check the memory, the total memory capacity of the memory card should be 64K.
The memory is divided into blocks of bytes, and during the memory check operation, the unprocessed number of blocks is counted down as shown in (B) and (C) of FIG. 47.
Etc. Display the number of remaining blocks. Therefore, the initialization ends when the number of remaining blocks reaches 00 as shown in FIG.

If the same operation is carried out when the formatted memory card is loaded, the state of preparation for all erasure is brought about and the display of FIG. 47 (A) is made. And
When the trigger switch 19 is pressed, the format of the memory card is checked, and if it is detected that the memory card has been formatted, only the data stored in the management area is erased, and the entire erasing is completed, immediately FIG. 47
(D) end display. Therefore, this processing operation is completed in a short time.

Next, the erase mode selecting operation will be described. As shown in Table 10, there are "A mode", "B mode", and "C mode" as the selected erase modes. The reason why some erasing modes are required is that various formats such as those in which the attribute information in the common area of the memory card is not written can be supported depending on the type of format.

[0091]

[Table 10]

That is, the "A mode" is a mode in which the all erasing operation described in FIG. 47 is performed, and for an unformatted memory card, memory check and management area writing are executed to perform formatting. Only the recorded data in the management area is erased for the existing memory card.
In the "B mode" erasing operation, memory check and management area writing are performed regardless of the format.
Further, in the "C mode" erasing operation, when the management area is written, the attribute information of the common memory is not written. The selection of these modes is made by repeatedly pressing the UP switch 14c while pressing the ERASE switch 14f.

FIG. 48 shows the display screen of the display unit 13 or the monitor when the erase mode is selected. (A), (B) and (C) of FIG.
Repeatedly pressing the UP switch 14c while pressing f, the "A mode", "B mode", "C" of the erase mode.
It is a display screen when "Mode" is selected. The "ERASE" display blinks when each mode is designated. Further, when the UP switch 14c is pressed, the mode is returned to the reproduction mode, and the display screen during normal reproduction is displayed as shown in FIG. 48 (D).

FIG. 49 shows the ERASE switch 14f and U.
It is a flowchart of a subroutine "UP switch process" of a process of pressing the P switch 14c and selecting the mode. When this routine is called when the UP switch 14c is pressed, it is checked in step S171 whether the ERASE switch 14f is on or off. If it is off, the routine returns. If it is on, the process proceeds to step S172. Then, it is checked whether the memory card can be erased. This check checks whether the memory card is write-protected,
It is checked whether the type of the memory card is, for example, an I / O card or the like in which attribute information for prohibiting access is recorded. If it cannot be erased, an error message is displayed on the display unit 13 or the monitor as shown in FIG. 50, and this routine ends. If it is erasable, the process proceeds to step S173.

In step S173, it is checked whether or not the all erasure preparation mode has already been entered. If it is not in the all-erase preparation mode, the all-erase preparation flag is set in step S174, and "ERAS" is set in step S175.
The "E" display is blinked and the "-A" is displayed. afterwards,
If the UP switch 14c is not pressed, step S17
The timer for 5 seconds is set at 5 and this routine is finished. If the check in step S173 indicates that the current mode is the all-erasure preparation mode, the process jumps to step S177 to increment the erase mode index corresponding to each erase mode. Then, in step S178, the erase mode index is checked. If the erase mode is already "C mode", the all erase preparation flag is cleared in step S179, and "ERAS" is set in step S180.
The "E" display is turned off and the process returns from this routine.

Next, regarding the subroutine "trigger switch processing" for operating the trigger switch 19 to erase,
This will be described with reference to the flowchart of FIG. Step S1
91, 192, 193, the all erase preparation mode is "A
Mode "," B mode ", or" C mode ", and jumps to steps S196, 197, and 198, respectively, and the subroutines" all erase A mode processing "and" all erase B mode processing "to be described later are performed. , "All erase C mode processing" is called. If neither of the above modes is set, the ERASE switch 14 is pressed in step S194.
Check on / off of f. If it is off, this routine is ended, but if it is on, the process proceeds to step S195, and the one-frame erasing process described later is called. Then, after erasing one frame, this routine ends.

FIG. 52 is a flowchart of the subroutine "all erasure A mode processing" called in step S196. When this subroutine is called, the "ERASE" display is turned on in step S201, and it is checked in step S202 whether or not the data can be erased. This process is the same check as the process of step S172 of FIG. 49, and is a confirmation process of the presence or absence of write protection. If the data cannot be erased, the process jumps to step S208 to display an error on the display unit 13 or the monitor (see FIG. 50).
(See also), a warning is given by the buzzer, and this routine ends.

If erasing is possible, step S20
Proceed to 3 to check the boot sector. That is, if the data in the boot sector is already known, the memory check is not necessary, so that only the management information needs to be rewritten, and the process proceeds to step S204. However, as a result of checking the boot sector, if the boot sector is not known,
If it is determined that the card is unformatted, a memory check is performed, so the process jumps to step S209.
It takes a long time to perform all deletion processing such as memory check.

In step S204, the chain data of FAT is cleared, and data 0 is written at the head of the directory entry in step S205. Then, the process proceeds to step S206 to display the end of erasure, and in step S207, the display unit 13 and the monitor are returned to the normal display state, and this routine is finished. Above step S209
If you proceed to, check the memory capacity of the card. This inspection reads the memory capacity data recorded in the device information tuple. If the data is not recorded, the memory is inspected to obtain the memory capacity. Then, in step S210, the total memory capacity is divided by, for example, 64 Kbytes, and the value of the quotient is displayed as the unchecked remaining amount. In step S211, a memory check is performed, and the unchecked memory remaining amount is displayed in units of 64 Kbytes. The memory check is an operation in which the values 55H and AAH are sequentially written every 64 Kbytes, the write data is read, and the values match. Then, the process is continued until the remaining amount becomes 0. After that, in steps S212 to S215, data such as attribute information, boot sector, FAT, and root directory is written to complete the complete erasing, and the process proceeds to step S206. The value of the attribute information and other write data differs depending on the memory capacity of the memory card.

FIG. 53 shows step S197 of FIG.
6 is a flowchart of a subroutine "all erase B mode processing" called in step S6. In this subroutine, the "ERASE" display is turned on in step S221, and it is checked in step S222 whether erasure is possible. If erasing is not possible, the process jumps to step S232 to display an error and terminates this routine. If it is erasable, the process proceeds to step S223 and thereafter. This step S22
The process from S3 to S231 is performed in steps S209 to S215 and steps S206 and S2 in FIG.
This is the same as the series of erase operations of 07.

FIG. 54 shows step S198 of FIG.
8 is a flowchart of a subroutine "all erasing C mode processing" called in step 1). The processing shown in steps S241 to S251 in this subroutine is the same processing as that in the "all erase B mode processing" subroutine shown in FIG. 53 except for writing the attribute information in step S226.

FIG. 55 shows step S195 of FIG.
6 is a flowchart of a subroutine "one-frame erasing process" called in step 1. In this subroutine, it is checked in step S261 whether erasure is possible. If erasure is not possible, the process jumps to step S266 to display an error and terminates this routine. If it is erasable, the process proceeds to step S262 and thereafter.

At step S262, the "ERASE" display is turned on, and at the step S263, 0E indicating that the head of the directory entry of the frame being reproduced is an erased frame.
Write 5H. In step S205 of FIG. 52, 0 is written in the directory entry, which means that the directory and subsequent directories are unused.
In the case of this one-frame erasing process, 0E5H is written to record that it is one-frame erasing. Further, in step S264, the FAT chain pointed to by the directory entry pointer is cleared to zero. Then, the process proceeds to step S265,
The deletion completion is displayed, and in step S266, the display unit 1
3. The monitor is returned to the normal display state and this routine is finished.

FIG. 56 is a diagram showing the leading portion of the directory entry in which one frame has been erased in step S263. In this way, 0E5H is written at the beginning of the directory entry for the fourth frame, indicating that the frame has been erased independently. Also, since 00H has been written for the sixth frame, it is not recorded after that. It shows that it is in a state. In this way, it is possible to distinguish a file erased in units of one frame from a file that is not recorded thereafter.
Further, it is possible to write 00H at the beginning of the directory entry and quickly set the unrecorded state in the directory entry and thereafter.

In the above example, the erasing has been described. However, this erasing operation includes two operations of formatting the medium and erasing the data, and the camera formats as necessary. The function of selecting one of the erase operation and the erase operation has been described. In the above examples, when the unformatted card is attached, the medium is formatted by the user's operation of erasing all, and the medium becomes usable.

Therefore, for a user who is unfamiliar with the concept of formatting, the card format is checked when the card is mounted, and if it is not formatted, a warning to that effect is given, and the formatting is performed by operating the ERASE switch, for example. It is also possible to configure. This process is shown in the flowchart of FIG. The "DOS formatted" in the flowchart indicates that the attribute information, boot sector, FAT, and directory are correctly written, and "DSC formatted" means that the necessary control file is written. It shows the state of being. Further, in order to execute the above format, a format switch may be separately provided, or as described above, the ERASE switch or the like may also be used.
