It is possible to confirm the result of the operation command.

  The CPU 1 is connected to a SIM socket 6B, which is a loading section into which a line subscriber information card (hereinafter referred to as SIM) 9 is detachably loaded by a control line. The SIM 9 is a medium having a card shape in which line subscriber information and the like are stored.

  In a state where the SIM 9 is mounted on the SIM socket 6B, the CPU 1 performs read control of various data from the SIM 9 and write control of various data to the SIM 9.

  Further, the CPU 1 is connected to a serial I / F 10 which is a serial communication means for performing serial transmission with other information devices via a serial signal line 14. The serial I / F 10 includes a serial I / F 10. Other information equipment, that is, external information equipment 16 (for example, a mobile phone device, a portable terminal device (notebook personal computer), an electronic camera, etc.) is electrically connected by the cable 15. As a result, various data is transferred between the information communication device 21 and the external information device 16 via the serial I / F 10 and the serial cable 15.

  A data communication operation performed in the information communication device 21 configured as described above will be briefly described below.

  For example, when a PC card type telephone is attached as the PC card 22 and a portable terminal device (hereinafter referred to as a PC) or an electronic camera is connected as the external information device 16, the CPU 1 is connected to a PC, an electronic camera ( 16) receives a data file, an image data file, etc. from the serial cable 15 and the serial I / F 10 and controls the PC card I / F 5 to output the data file etc. to the PC card type telephone (22). . Thereby, the data file or the like is transmitted to the communication partner.

  Further, the data file, image data file, etc. transmitted from the communication partner to the PC card type telephone (22) are received by the CPU 1 by controlling the PC card I / F 5, and the serial I / F 10, serial cable. 15 to the PC and the electronic camera (16). In response to this, the external information device 16 such as the PC or the electronic camera records the data file or the like in its own storage device. In this way, the information communication device 21 performs data communication with the communication partner.

  On the other hand, when a portable telephone is connected as the external information device 16 by the serial cable 15 and a storage medium such as an ATA card is inserted as the PC card 22 in the PC card socket 6A, the CPU 1 uses the PC card I / F 5 Are read out, the data file, the image data file, etc. recorded in the storage medium (22) are read out and output to the portable telephone (16) via the serial I / F 10 and the serial cable 15. Thereby, the data file or the like is transmitted to the communication partner.

  A data file, an image data file, and the like transmitted from the communication partner to the mobile phone (16) are input to the CPU 1 via the serial I / F 10 and the serial cable 15 under the control of the CPU 1. Then, the CPU 1 controls the PC card I / F 5 to output the data file or the like to the storage medium (22), and the storage medium (22) stores it. In this way, the information communication device 21 performs data communication with the communication partner.

  FIG. 2 is a schematic perspective view showing the external shape of the information communication device 21 of the first embodiment.

On the upper surface of the information communication device 21, an LCD 8a forming the display unit 8 and an operation panel unit are provided. The operation panel section includes keys of each group forming the key input section 7 as the operation means, that is,
An alphabet key 17 in which alphabets “A to Z” and keys of “− (hyphen)” are arranged in a group;
Numeric keys “0-9”, ten keys 19 in which each key of “, (comma)” and “. (Point)” is arranged in a group,
A start key 18 for instructing completion of input of an operation command,
A function key 20 in which a plurality of keys for instructing a specific operation command are arranged as a group;
Etc. are arranged.

FIG. 2 shows a so-called QWERTY array as an example of the alphabet key 17 array. As an example of the function key 20,
"$ (Dollar)" key 20a for instructing display of line usage information such as billing information,
"PASS" key 20b for instructing mode switching to the password setting mode,
A “TEL” key 20c for giving an instruction to start the communication mode;
Is shown.

  On the other hand, the side wall surface is provided with the connector portion 10A of the serial I / F 10 and the SIM socket 6B. A connector 15A on one end side of the serial cable 15 is connected to the connector portion 10A, and an external information device 16 is connected to the other end side of the cable 15. A SIM 9 is attached to the SIM socket 6B.

  Further, the PC card socket 6A is provided on the other side wall surface, and a PC card type telephone as the PC card 22 is attached to the PC card socket 6A.

  Then, the operator operates the various keys (17, 18, 19, 20) as necessary, so that the information communication device 21, the PC card type telephone (22), and the external information device 16 are connected. Can be used for data communication.

  The first communication mode among the operations at the time of communication performed by the information communication device 21 of the first embodiment configured as described above will be described below with reference to the flowchart of FIG.

  Here, as shown in FIG. 2, a PC card type telephone is mounted as the PC card 22 in the PC card socket 6A, and a portable terminal device as the external information device 16 is connected to the serial I / F 10. Assume that an electronic camera or the like is connected.

  The information communication device 21 is always monitored for an incoming signal by the CPU 1 in a state where power is supplied and the communication mode is not set to the communication mode. Here, the incoming signal indicates a communication request signal sent from another information device (communication partner) to the PC card type telephone (22) attached to the information communication device 21. That is, when an incoming signal is input to the PC card type telephone (22) of the information communication device 21 by making a communication request (making a call) from the communication partner via the telephone line, this PC card type The telephone (22) transmits a character string signal such as “RING” or “CALL” to the CPU 1, and the CPU 1 receives (detects) the character string signal to perform communication. You can see if there was a request.

  First, in step S1, the CPU 1 detects an incoming signal. If an incoming signal is detected, the process proceeds to step S5. If no incoming signal is detected, it is determined that the communication can be started, and the first communication mode for making a call to another information device is entered. Then, the process proceeds to the next step S2.

  In step S2, after the operator inputs the telephone number by operating the numeric keypad 19, in step S3, when the TEL key 20c among the function keys 20 is pressed, the information communication device 21 performs communication. An instruction command signal for starting (transmitting) is input to the CPU 1, and the process proceeds to the next step S4.

  In step S4, the CPU 1 receives the communication start instruction command in step S3 described above, controls the PC card I / F 5, and inputs the telephone input to the PC card type telephone (22) mounted in the PC card socket 6A. Send number information and call instructions. In response to this, the PC card type telephone (22) performs a call origination operation, that is, an operation for making a call, and proceeds to the processing of the next step S5.

  In step S5, it is determined whether or not the connection with the communication partner is successful. Here, when a character string signal such as “connect” is transmitted from the PC card type telephone (22) to the CPU 1, the CPU 1 determines that the connection with the communication partner is successful, and the next step S6. On the other hand, when a character string signal such as “fail” is transmitted from the PC card type telephone (22) to the CPU 1, the CPU 1 determines that the connection with the communication partner has failed, End the sequence of (End).

  In step S5 described above, when it is determined that the connection is successful and the process proceeds to step S6, data communication is performed with the communication partner in step S6. In the data communication performed here, the data file recorded in the external information device 16 is transmitted to the communication partner, or the data file transmitted from the communication partner is received, and the external information device 16 For example, recording in the storage device.

  When the data communication is completed, the process proceeds to the next step S7, where the connection state with the communication partner is disconnected. That is, switching from the communicable state to the communicable state is possible. In this case, for example, when the operator presses the TEL key 20c during communication connection, a communication disconnection signal is sent to the CPU 1, and the CPU 1 receiving this signal controls the PC card I / F 5 to control the PC card type telephone. The communication is disconnected by (22), or the same communication disconnection operation is performed by the communication partner. Then, the process proceeds to the next step S8.

  In step S8, the CPU 1 acquires line usage information such as billing information related to the communication usage fee that was performed immediately before. This billing information, etc. is obtained by receiving a service in which various types of information are transmitted from a management company (for example, a telephone station) that manages the entire network immediately after disconnection. .

  In this case, the state after the line disconnection operation in step S7 described above is a state in which the connection state with the communication partner is simply disconnected, and the connection state with the line network management company is maintained. ing. Then, using the time immediately after the line disconnection operation, various information can be obtained from the line network management company. When the information transmission from the line network management company is completed, the line network management company The connection state between the PC card type telephone 22 and the line network is completely disconnected.

  In addition to the above-mentioned means, the above billing information etc. can be obtained by calling the specific telephone number of the center managing the billing information of the above-mentioned network management company etc. when desired. If there is a service that can acquire the service, there is a means of using this service.

  That is, after the communication with the communication partner is completed and the line disconnection operation is performed, the CPU 1 of the information communication device 21 performs connection operation (so-called auto dial, auto login) by automatic operation to the specific telephone number. To obtain billing information related to the last communication usage fee. In this case, the connection state between the PC card type telephone (22) and the line network is completely cut off by the line disconnection operation performed after the communication with the communication partner is terminated. 21 needs to be completely released from the communication state.

  Then, the process proceeds to the next step S9. In this step S9, the CPU 1 determines, for example, date information, usage time information, destination telephone number information, billing information (utilization information) based on the acquired line utilization information such as billing information. Detailed information such as (charge information) is created and recorded in the SIM 9, and then the process proceeds to the next step S10. In this step S10, the detailed information is displayed on the LCD 8a, and this series of sequences is completed. (End). Here, the CPU 1 is a writing means for writing and recording the acquired line usage information in the SIM 9 and serves as a usage information recording means.

Table 1 shows an example of a display form of the detailed information displayed on the LCD 8a in step S10 described above.

  By the way, when using the line subscriber information card (SIM) 9, in order to ensure the security, it is conceivable to set a unique password for each card. This password must be set by the SIM9 manufacturer and cannot be easily rewritten by the user. This password is used to strictly maintain confidentiality, such as when the SIM 9 is properly purchased, only the purchaser is informed.

  When such a strictly managed SIM 9 is mounted on the information communication device 21 and used, when the information communication device 21 performs registration by performing password registration corresponding to each SIM 9 in advance. In the sequence of the communication mode, if the password of the attached SIM 9 matches the password registered in the information communication device 21, that is, if a sequence for performing a password check is added, the password of the SIM 9 is not known. For example, if a person illegally obtains SIM9, it cannot be used easily. Therefore, security can be improved.

  Therefore, in the information communication device 21 of the first embodiment, the password setting mode shown in the flowchart of FIG. 4 is prepared, and the password set in the password setting mode matches the password of the attached SIM 9. A second communication mode is added to which a password check sequence is added.

  That is, in the information communication device 21, in order to set a password, when in a state other than the communication mode, the password can be switched to the password setting mode by pressing the PASS key 20b.

  As described above, the information communication device 21 always monitors the incoming signal by the CPU 1 in a state where power is supplied and is not set in the communication mode. The mode switching signal is always monitored.

  That is, when power is supplied to the information communication device 21 and it is in a state other than the communication mode, the CPU 1 monitors whether or not the PASS key 20b is pressed in step S11. When the operator switches to the password setting mode by pressing the PASS key 20b, the input signal is detected by the CPU 1. Thereby, the process proceeds to the password setting mode after the process of the next step S12.

  On the other hand, if the PASS key 20b is not pressed, the normal operation sequence, that is, a state other than the communication mode is maintained without shifting to the password setting mode, and the CPU 1 continues to monitor incoming signals and the like.

  In step S11 described above, when the PASS key 20b is pressed and the process proceeds to the password setting mode in step S12 and subsequent steps, in this step S12, the operator operates the alphabet key 17 and the numeric keypad 19 to set the SIM9. Enter the password. Then, upon receiving this password input signal, the CPU 1 sets a password in the next step S13. As a result, the SIM 9 corresponding to the password input in step S12 described above can be used in the information communication device 21. Then, it returns to the state immediately before the transition to the password setting mode.

  Note that the password information set in step S13 described above is stored in the RAM 4 or the like as reference data, and is referred to as needed in the password check sequence when the information communication device 21 performs a communication operation. Will be. In this case, the RAM 4 serves as a password storage unit that stores a character string input by operating the alphabet key 17 or the numeric key 19 of the key input unit 7 as an operation unit as a password.

  Next, of the operations at the time of communication performed by the information communication device 21 of the first embodiment, a second communication mode to which a password check sequence is added will be described below with reference to the flowchart of FIG.

  First, in step S21, the operator inputs a telephone number by operating the numeric keypad 19. Subsequently, in the next step S22, pressing the TEL key 20c starts communication from the information communication device 21 ( An instruction command to make a call is input to the CPU 1, and the process proceeds to the next step S23.

  In step S23, upon receiving the communication start instruction command, the CPU 1 reads out the password information set in the SIM 9 and the password set and registered in advance in the password setting mode (see FIG. 4). Compare, that is, check the password. In this case, when the CPU 1 loads the SIM 9 (card-shaped medium) into the SIM socket 6B (loading unit) and performs data communication using the public telephone line, the unique password information set in the SIM 9 and It serves as a password check means for comparing password information stored in the RAM 4 (password storage means) by the alphabet key 17 or the numeric keypad 19 (operation means) in the key input unit 7 in advance.

  If the two passwords match, the process proceeds to the next step S24. If the two passwords do not match, the second communication mode is terminated and the normal standby state is restored.

  As a result of the password check in step S23 described above, when the setting passwords on the SIM 9 side and the information communication device 21 side match and the process proceeds to step S24, in step S24, the CPU 1 instructs the communication start in step S22 described above. Based on the command, the PC card I / F 5 is controlled, and the telephone number information and the transmission command input in step S21 are transmitted to the PC card type telephone (22) mounted in the PC card socket 6A. As a result, the PC card type telephone (22) executes a transmission operation. Then, the process proceeds to the next step S25.

  In step S25, it is determined whether or not the connection with the communication partner is successful. Here, when a character string signal such as “connect” is transmitted from the PC card type telephone (22) to the CPU 1, the CPU 1 determines that the connection with the communication partner is successful, and the next step S26. On the other hand, when a character string signal such as “fail” is transmitted from the PC card type telephone (22) to the CPU 1, the CPU 1 determines that the connection with the communication partner has failed, End the sequence of (End).

  If it is determined in step S25 that the connection is successful and the process proceeds to step S26, various data are transmitted to the communication partner (data communication) in step S26. When this data communication ends, a line disconnection operation is performed. The processing after the line disconnecting operation is exactly the same as the processing after step S7 shown in FIG.

  As described above, according to the first embodiment, the SIM socket 6B is provided on the information communication device 21 side, and the SIM 9 is detachably disposed in the SIM socket 6B. By attaching the SIM 9 to the mobile phone, communication such as data transmission using a public telephone line that requires the SIM 9 can be easily performed.

  In addition, a password setting mode in which a password corresponding to the password set in the SIM 9 is set and registered in advance, and a setting password on the SIM 9 side and a password set and registered on the information communication device 21 side are compared (password check). Since the second communication mode is provided, it is possible to improve the security by preventing the SIM 9 illegally obtained by a third party from being easily used.

  It should be noted that in the operation sequence of the first communication mode described above, the detailed information display form (see Table 1) displayed on the LCD 8a in step S10 (see FIG. 3) is not limited to this, but another display form. It may be. Below, the other example about the display form of detailed information is demonstrated.

  FIG. 6 is a main part schematic perspective view showing a modification of the information communication device 21 of the first embodiment. In the information communication device 21A in this modified example, a cursor movement key 25 is added and arranged as a part of the key operation unit 7 provided in the operation panel unit. In addition, about another structural member, it shall be the same as that of the above-mentioned 1st Embodiment, The description is abbreviate | omitted.

  The cursor movement key 25 is composed of four triangular keys arranged on the upper surface of the information communication device 21A and in the vicinity of the display unit 8 (LCD 8a) of the operation panel unit on one end side. The four keys are arranged such that each of the triangular vertices faces outward, and the four keys form a diamond shape.

  The four keys forming the cursor movement key 25 are an upward movement key 25a in which a triangular vertex points upward, a downward movement key 25b in which a triangular vertex points downward, and a triangular shape. The left movement key 25c has a vertex pointing in the left direction, and the right movement key 25d has a triangular vertex pointing in the right direction.

  The communication operation performed in the information communication device 21A configured as described above is the same as that in the first embodiment described above (see FIG. 3), but the display form of detailed information and the like performed in step S10 is different.

  That is, the display form of the detailed information and the like in the first embodiment described above is such that only information related to the communication performed immediately before is displayed on the LCD 8a as shown in Table 1. In the modified example, all of the communication history recorded in the SIM 9 can be displayed.

  The SIM 9 is configured to record all the detailed information created based on the acquired billing information and the like every time communication is performed. This detailed information can be displayed on the LCD 8a by pressing the $ key 20a of the function keys 20.

  Therefore, the operator transmits a billing information display signal display command to the CPU 1 by pressing the $ key 20a, and the CPU 1 receives all the detailed information such as billing information recorded in the SIM 9 in response to the command. The data is read out and displayed on the LCD 8a. At this time, the display form of the detailed information displayed on the LCD 8a is substantially the same as that in Table 1. As shown in FIG. 6, the date information is displayed in the A column on the left side of the LCD 8a, and the above A in the B column. The usage time information at the time of communication in the column, the destination telephone number information at this time in the column C, and the charging information (usage fee information) at this time are displayed in the column D, respectively.

  Here, when all the detailed information cannot be displayed on the LCD 8a at the same time because the number of detailed information recorded in the SIM 9 is large, the operator can select the up movement key 25a or the down movement key from among the cursor movement keys 25. By operating 25b, the information displayed on the screen can be scrolled in the vertical direction, whereby the display range can be changed and desired detailed information can be displayed.

  With this configuration, in the above-described modification, the same effects as those of the first embodiment described above can be obtained, and the cursor movement key 25 is additionally provided to relate to the communication recorded in the SIM 9. Since all the detailed information such as billing information is displayed on the LCD 8a, it is possible to easily refer to the communication history such as the detailed information whenever desired.

  Next, a second embodiment of the present invention will be described below. In the second embodiment, the information communication device is an electronic camera having a communication function.

  FIG. 7 is a block configuration diagram showing the configuration of the electronic camera of the second embodiment.

  The electronic camera 31 according to the second embodiment is formed by a control circuit unit formed by a control circuit and the like, and a component related to shooting of a subject image and recording of image data (video signal) obtained by shooting. It is composed of a camera unit and the like.

  The control circuit unit has substantially the same configuration as the information communication device (21) of the first embodiment, and the CPU 1 controls the entire electronic camera 31, and the control program in which the CPU 1 performs various control operations. Is stored in the ROM 3, the RAM 4 that temporarily stores various data, the PC card socket 6 A in which the PC card 22 is mounted, and the PC card socket 6 A connected to the PC card 22 based on the control of the CPU 1.

  An LCD 8a forming the display unit 8 is provided on the upper surface of the electronic camera 31, and various operation keys corresponding to the key input unit 7 serving as the operation unit, that is, a photographing start signal is provided in the vicinity of the LCD 8a. Alternatively, a video trigger key 40 that is a video recording instruction means and a communication instruction means for generating a communication start signal, a function key 41 for instructing a specific operation command, a MODE key 42 for instructing mode switching, and various keys are used for input. A cursor movement key 25 comprising an ENTER key 43 for determining a character to be entered, a character selection key 44 for selecting a character for input, and four triangular keys for changing the display range of information displayed on the LCD 8a. Etc. are arranged.

  The four keys forming the cursor movement key 25 are an upward movement key 25a in which a triangular vertex points upward, a downward movement key 25b in which a triangular vertex points downward, and a triangular shape. The left moving key 25c whose vertex points to the left direction and the right moving key 25d whose triangular vertex points to the right direction are formed by four key groups.

  On the other hand, the PC card socket 6A and the SIM socket 6B are provided on one side of the electronic camera 31, and the PC card type telephone SIM SIM9 as the PC card 22 is provided in both the sockets 6A and 6B. It is installed.

  A photographing optical system 48 formed by a photographing lens or the like is disposed on the front surface of the electronic camera 31, and the CCD 32 or the like (shown in FIG. 8) is located behind the photographing optical system 48 in the camera body. Not shown, see FIG. 7).

  In the electronic camera 31, the operator can select a desired operation mode by pressing the MODE key 42. As the operation mode, a “recording mode”, a “reproduction mode”, and a “transmission mode” are prepared, and can be sequentially switched every time the MODE key 42 is pressed.

  The operation in each operation mode of the electronic camera of the second embodiment configured as described above will be briefly described below.

  First, in the recording mode, the optical image formed by the photographing optical system 48 is converted into an electrical video signal by the CCD 32 and output. The video signal (analog) is A / D converted through the process processing unit 33. Is input to the device 34 and digitized thereby. The digitized video signal is temporarily stored in the frame memory 36 via the video bus 51 and simultaneously output to the D / A converter 35. After being converted into an analog signal, the video signal is output. It is output to an external display device (not shown) through the terminal 39 and displayed as a continuous video.

  When the video trigger key 40 is pressed to generate a shooting start signal, first, the digital video signal stored in the frame memory 36 is output to the companding circuit unit 38 via the video bus 51. The compression process is performed. The compressed video signal (digital image data) is stored in the flash memory 29 via the system bus 2.

  Further, the video signal (digital image data) which has been shot and compressed is stored in the flash memory 29 and can also be recorded in an external storage medium. In this case, with the storage medium card mounted as the PC card 22 in the PC card socket 6A, the key input unit 7 is operated to instruct the CPU 1 to perform the recording operation on the PC card 22. give. The CPU 1 receives this instruction command, controls the PC card I / F 5, and records the video signal on the PC card (storage medium card) 22 through the PC card I / F 5.

  On the other hand, in the reproduction mode, the CPU 1 reads the video signal (digital image data) recorded in the flash memory 29 or the PC card 22 and outputs it to the companding circuit unit 38 via the system bus 2. The companding circuit 38 decompresses the video signal and restores it to an uncompressed video signal (digital). This video signal is temporarily stored in the frame memory 36 via the video bus 51. The video signal temporarily stored in the frame memory 36 is repeatedly read out by the D / A converter 35 and sequentially converted into an analog signal, and is output as a reproduced image from the video signal output terminal 39 to the external display device. As a result, it is reproduced.

  In the recording mode and the reproduction mode described above, the CPU 1 sets the control circuit unit 37 via the system bus 2, and the control circuit unit 37 issues various instruction commands based on the set operation mode. Various operations are made by emitting. That is, the control circuit unit 37 is based on an instruction command from the CPU 1 and is connected to the A / D converter 34, the D / A converter 35, the frame memory 36, the compression / decompression circuit unit 38, and the PC card, which are connected by control lines. I / F5 and the like are controlled.

  FIG. 9 is a flowchart showing the operation of the electronic camera 31 of the second embodiment.

  First, in steps S31 to S33, the operation mode is determined. That is, the CPU 1 determines the selected operation mode by detecting an input signal from the MODE key 42 that is generated when the MODE key 42 is pressed by the operator.

  In step S31, it is determined whether a recording mode has been selected. If it is determined that the recording mode has been selected, the process proceeds to a recording mode sequence. If the recording mode has not been selected, the process proceeds to the next step S32.

  In step S32, it is determined whether the playback mode has been selected. If it is determined that the playback mode is selected, the process proceeds to the playback mode sequence. If the playback mode is not selected, the process proceeds to the next step S33.

  In step S33, it is determined whether a transmission mode has been selected. Here, when the transmission mode is not selected, it is determined that the MODE key 42 is not operated, and the operation mode determination sequence (steps S31 to S33) is returned to the initial state. The same processing is repeated until the operation mode is selected. On the other hand, if it is determined that the transmission mode is selected, the process proceeds to the next step S34.

  The processing after step S34 is a transmission mode sequence. In this transmission mode, first, in step S34, the CPU 1 monitors whether or not the PC card type telephone (22) has received an incoming signal, for example, a character string signal such as “RING” or “CALL”. If an incoming signal is detected, the process proceeds to step S38. If no incoming signal is detected, the process proceeds to the next step S35.

  In step S35, the operator inputs a telephone number by operating the character selection key 44 and the ENTER key 43. After this telephone number input operation is completed, the process proceeds to the next step S36. A specific example of the telephone number input operation performed here will be described with reference to FIGS.

  In step S36, the operator inputs an instruction command to start communication (to make a call) to the CPU 1 by pressing the video trigger key 40, and the CPU 1 receives the instruction instruction in the next step S37. The card I / F 5 is controlled to transmit the telephone number information and the transmission command input in step S35 to the PC card type telephone (22) mounted in the PC card socket 6A. As a result, the PC card type telephone (22) executes a transmission operation. Then, the process proceeds to the next step S38.

  In step S38, it is determined whether or not the connection with the communication partner is successful. Here, when a character string signal such as “connect” is transmitted from the PC card type telephone (22) to the CPU 1, the CPU 1 determines that the connection with the communication partner is successful, and the next step S39. In step S39, data communication is performed with the communication partner.

  That is, here, the CPU 1 uses the PC card type telephone (22; card-shaped communication device) mounted in the PC card socket 6A (mounting unit) to perform data communication using the public telephone line. Function as. The CPU 1 similarly performs data communication when image data is communicated using a public telephone line by another information device connected to the serial I / F 10 (serial communication means) via the serial cable 15. Acts as a means.

  This data communication is an operation such as transmitting image data or the like recorded in the flash memory 29 to a communication partner or recording image data or the like transmitted from the communication partner to the flash memory 29. When the communication ends, the process proceeds to the next step S40.

  On the other hand, if a character string signal such as “fail” is transmitted from the PC card type telephone (22) to the CPU 1 in step S38, the CPU 1 determines that the connection with the communication partner has failed. Then, the process returns to the above-described step S31, and the subsequent sequence is repeated.

  In step S40, the connection state with the communication partner is disconnected by the PC card type telephone (22) or the communication partner, and in the next step S41, billing information and the like regarding the communication usage fee performed immediately before is acquired. Then, the process proceeds to the next step S42.

  In step S42, the CPU 1 creates detailed information such as date information, usage time information, destination telephone number information, billing information (usage fee information) based on the billing information acquired in step S41 described above, After this is recorded in the SIM 9, the process proceeds to the next step S43, where the detailed information is displayed on the LCD 8a. Thereafter, the processing returns to the above-described step S31, and the subsequent processing is repeated.

Table 2 shows an example of a display form of the detailed information displayed on the LCD 8a in step S43 described above.

  FIG. 10 is a top view of an essential part showing a part of the electronic camera 31 of the second embodiment, and shows the LCD 8a and each operation key. With reference to FIG. 10, another display mode of the detailed information in the sequence of the billing information display mode in step S43 described above will be described.

  The charging information display mode is started when the function key 41 is operated by the operator. That is, when an input signal (billing information display command) from the function key 41 is transmitted to the CPU 1, the CPU 1 reads all communication history information such as detailed information recorded in the SIM 9 in response to this, and the LCD 8 a Display above. This series of operation modes is a billing information display mode.

  When all the detailed information cannot be displayed on the LCD 8a at the same time because the number of detailed information recorded in the SIM 9 is large, the operator presses the up movement key 25a or the down movement key 25b among the cursor movement keys 25. By operating, the display range can be changed by scrolling the information displayed on the screen in the vertical direction, and desired detailed information can be displayed. In FIG. 10, the display on the LCD 8a is simplified.

  By the way, the procedure of the telephone number input operation performed in step S35 in the above-described transmission mode operation sequence will be described.

  FIG. 11 and FIG. 12 are main part top views showing a part of the electronic camera 31 of the second embodiment.

  In the transmission mode of the electronic camera 31, when inputting a telephone number, the operator first operates the character selection key 44. Each time this character selection key 44 is pressed, the numbers 1 to 9 can be sequentially displayed at predetermined positions on the LCD 8a (in FIG. 11 and FIG. 12, the area E located at the lower right of the LCD 8a). It can be done. At this time, the number displayed in the area E of the LCD 8a is in a blinking state to indicate that it is indeterminate.

  The operator presses the character selection key 44 to display a desired number on the LCD 8a, and then presses the ENTER key 43 to determine the number. Then, a fixed number is lit up and displayed at another predetermined position of the LCD 8a (region F located at the lower left of the LCD 8a). In addition, the state shown in FIG. 12 shows a state after inputting up to the fourth digit and confirming the number of four digits.

  In this way, the operator displays all digits of the telephone number in the area F of the LCD 8a and sets a desired telephone number. Finally, the video trigger key 40 is pressed (see step S36 in FIG. 9), and the telephone number information and the transmission command are transmitted to the PC card type telephone (22). Thereby, the telephone number input operation is completed.

  FIG. 13 is a flowchart in the case where sub-modes such as the billing information display mode and the password setting mode are added to the transmission mode described above, and shows the operation in the transmission mode in more detail.

  First, in steps S51 to S53, the operation mode is determined. This is exactly the same as the operations in steps S31 to S33 in the operation sequence shown in FIG. Therefore, description of the operation mode determination sequence is omitted here.

  When it is determined in step S53 in FIG. 13 that the transmission mode has been selected and the processing proceeds to the next step S54, the CPU 1 determines that the PC card type telephone (22) has received an incoming signal, for example, “RING”. , Whether or not a character string signal such as “CALL” is received is monitored. If an incoming signal is detected, the process proceeds to step S65 (symbol B, see FIG. 16) in the second transmission mode described later. If no incoming signal is detected, the next step S55 is performed. Proceed to the process.

  In step S55, the CPU 1 checks whether or not the character selection key 44 has been operated by the operator. Here, when an input signal from the character selection key 44 is detected, that is, when a telephone number input operation is performed by the operator, the mode shifts to the second data transmission mode (see FIG. 16).

  On the other hand, if an input signal from the character selection key 44 is not detected in step S55, the process proceeds to the next step S56.

  In step S56, the CPU 1 checks whether or not the function key 41 has been operated by the operator. Here, when an input signal from the function key 41 is detected, the process shifts to the billing information display mode (refer to the description of FIG. 10), and after processing of this billing information display mode is executed, in step S57 again. It is confirmed whether or not the function key 41 has been operated by the operator. Here, when the input signal from the function key 41 is detected again, the process proceeds to the password setting mode. When this password setting mode is terminated, the process returns to the above-described step S51, and the subsequent processes are repeated.

  On the other hand, if neither the input signal from the function key 41 is detected in the above step S56 or step S57, for example, if the input signal from the MODE key 42 or the like is detected, the process returns to the above step S51. The subsequent processing is repeated.

  14 and 15 are main part top views showing a part of the electronic camera 31 of the second embodiment, showing the LCD 8a and each operation key. The setting operation procedure in the password setting mode sequence in step S57 described above will be described with reference to FIGS.

  In the password setting mode, when the operator sets a password, first, the character selection key 44 is operated. Each time this character selection key 44 is pressed once, numbers 1 to 9 and alphabetic characters up to alphabets a to z are positioned at a predetermined position on the LCD 8a (in FIG. 14 and FIG. 15, in the lower right of the LCD 8a). In the area E), it can be displayed sequentially. At this time, the numbers or English characters displayed in the area E of the LCD 8a are in a blinking state to indicate that they are unconfirmed.

  The operator presses the character selection key 44 to display desired numbers and English characters in the area E of the LCD 8a, and then presses the ENTER key 43 to determine the character to be input. When the ENTER key 43 is pressed, the determined numbers and English characters are displayed in a lit state at another predetermined position of the LCD 8a (area F located at the lower left of the LCd 8a). The state shown in FIG. 15 shows a state in which a 4-digit input character is confirmed. Here, since it is a password setting screen, confidentiality is required. Therefore, security needs to be considered. Therefore, “*”, which is the number of alternative characters corresponding to the number of input digits, is displayed without directly displaying the input specific numbers and English characters on the LCD 8a.

  In this manner, the operator operates the character selection key 44 and the ENTER key 43 to input and set a password corresponding to the setting password of the SIM 9 in the area F of the LCD 8a. Finally, when the video trigger key 40 is pressed, the character signal of the input password is stored in the RAM 4 or the like. Thereby, the password setting registration operation is completed.

  FIG. 16 is a flowchart showing the operation in the second data transmission mode in FIG. 13 described above. The second data transmission mode is substantially the same as the sequence after step S35 in the transmission mode of FIG. 9, except that a password check sequence is added as in the first embodiment. Different.

  Prior to the second data transmission mode, the operator first performs password setting registration in the password setting mode according to the procedure described with reference to FIGS.

  In step S55 of FIG. 13 described above, the character selection key 44 is operated, and a telephone number input operation is performed. At the same time, the process shifts to the second data transmission mode. The telephone number input operation (step S61) performed here is in accordance with the procedure described with reference to FIGS. When the video trigger key 40 is pressed (step S62), the CPU 1 receives this and performs a password check in step S63. Here, if the password of the SIM 9 matches the password registered in advance, the process proceeds to the next step S64, in which the CPU 1 displays the input telephone number information and the transmission command as the PC card. The data is transmitted to the PC card type telephone (22) via the I / F5. As a result, the PC card type telephone (22) performs a transmission operation. Then, the process proceeds to the next step S65.

  On the other hand, if they do not match as a result of the password check in step S63 described above, the processing returns to step S51 in FIG. 13 and the subsequent processing is repeated.

  In step S65, it is determined whether or not the connection with the communication partner is successful. Here, if a character string signal such as “connect” is transmitted from the PC card type telephone (22) to the CPU 1 and it is determined that the connection is successful, the process proceeds to the next step S66, and in this step S66, Data communication is performed with the communication partner. The processing from step S66 to S70 is exactly the same as the processing from step S39 to S43 in FIG.

  On the other hand, when a character string signal such as “fail” is transmitted from the PC card type telephone (22) to the CPU 1 in step S65 described above and it is determined that the connection has failed, the process returns to step S51 described above. The subsequent sequence is repeated.

  In step S70, when the display on the LCD 8a is performed, the sequence of the second data transmission mode is terminated, the processing returns to the above-described step S51, and the subsequent processing is repeated.

  As described above, according to the second embodiment, even in an electronic camera that can transmit captured image data and the like to a communication partner, the same effect as in the first embodiment can be obtained. Can do.

  FIG. 17 is a block diagram showing an electronic camera according to the third embodiment of the present invention. The third embodiment has basically the same configuration as the second embodiment described above. In the third embodiment, the recording medium section is further added to the second embodiment described above. 52, main power supply 53, transmission / reception signal processing circuit unit 54, RF unit 55 and the like are added.

  In other words, the electronic camera 31 of the third embodiment has a built-in RF unit 55 instead of the PC card type telephone (22), so that the electronic camera 31 itself can perform communication using radio waves for public telephone lines. Can be performed. Therefore, in the third embodiment, the same components as those in the second embodiment described above are denoted by the same reference numerals and the description thereof is omitted, and only different components are described below.

  The recording medium unit 52 is an image storage unit that stores a video signal obtained by the CCD 32 (imaging unit). The recording medium unit 52 is connected to the CPU 1 via the system bus 2 and is controlled by the CPU 1. At the same time, it is also connected to the control circuit section 37 by a control line, and the recording medium section 52 is controlled by the control circuit section 37 when recording and reproducing operations such as image data. ing.

  As the recording medium unit 52, for example, a storage device such as a flexible disk device, an optical disk device, and a hard disk device can be employed.

  On the other hand, the communication operation of the electronic camera 31 is controlled by the CPU 1 via the transmission / reception signal processing circuit 54 which is transmission / reception signal processing means, and is performed by the RF unit 55 which is communication means for performing data communication using a public telephone line. Done. The RF unit 55 is formed by members and circuits related to communication such as an antenna, and a video signal such as image data transmitted and received by the RF unit 55 is subjected to signal processing by the transmission / reception signal processing circuit unit 54. It is like that. The transmission / reception signal processing circuit unit 54 is connected to the CPU 1 via the system bus 2 and is controlled by the CPU 1. The transmission / reception signal processing circuit unit 54 is connected to the RF unit 55 through an analog signal line.

  The transmission / reception signal processing circuit unit 54 is connected to the main power supply 53 by a power supply control line 71, and the main power supply 53 is controlled by the transmission / reception signal processing circuit unit 54 such as on / off control. ing.

  In the electronic camera 31 of the third embodiment, a camera unit is provided as in the second embodiment (see FIG. 7). The subject image formed by the photographing optical system 48 of the camera unit is photoelectrically converted as a video signal by the CCD 32 as an imaging unit, and this video signal is output to the A / D converter 34 via the process processing unit 33. After being converted into a digital signal by the A / D converter 34, the video signal (digital image data) which is output to the companding circuit unit 38 through the video bus 51 and subjected to compression processing is converted into a system signal. The data is input to the CPU 1 via the bus 2. The video signal is output from the CPU 1 to the transmission / reception signal processing circuit 54 via the system bus 2.

  The transmission / reception signal processing circuit unit 54 performs transmission signal processing such as error correction and D / A conversion on the video signal (digital) output from the CPU 1 and outputs it to the RF unit 55 as an analog data signal. In addition, among analog signals received by the RF unit 55 and input to the transmission / reception signal processing circuit unit 54, video signals (analog) such as image data transmitted from a communication partner are received. Is subjected to reception signal processing such as A / D conversion and error correction decoding, and is output to the CPU 1 as a digital data signal.

  As described above, various analog signals received by the RF unit 55 are input to the transmission / reception signal processing circuit unit 54. Here, the analog signals received by the RF unit 55 are public telephones. This is a radio signal for the line. The RF unit 55 performs orthogonal demodulation processing or the like on the analog signal and outputs the analog signal as an analog data signal to the transmission / reception signal processing circuit unit 54, and at the same time, is output from the transmission / reception signal processing circuit unit 54. The analog data signal input to the unit 55 is subjected to orthogonal modulation processing or the like. As a result, video signals such as image data when communicating with the electronic camera 31 are output as radio signals for public telephone lines.

  When the signal received by the RF unit 55 and transmitted to the transmission / reception signal processing circuit unit 54 is an incoming call signal, the transmission / reception signal processing circuit unit 54 displays characters such as “RING” and “CALL”. The column signal is output to the CPU 1, and upon receiving this, the CPU 1 displays a character string or the like indicating the incoming signal on the display unit (LCD) 8 (display means).

  If the main power supply 53 of the electronic camera 31 is in an off state when the RF unit 55 receives an incoming signal, the transmission / reception signal processing circuit unit 54 receives the incoming signal and receives a power control line. 71 is provided with a function of switching the main power supply 53 connected by 71 to an ON state so that data communication can be started, a so-called incoming wakeup function. Therefore, the electronic camera 31 has a mode in which the CPU 1 always monitors the incoming signal even when the main power supply 53 is in the off state (hereinafter referred to as incoming wake-up mode).

  Further, the transmission / reception signal processing circuit unit 54 performs line connection processing under the control of the CPU 1. This line connection processing is performed when the RF unit 55 receives a signal indicating that the connection with the communication partner is successful and the signal is transmitted to the transmission / reception signal processing circuit unit 54 during communication operation. The signal processing circuit unit 54 outputs a character string signal such as “connect” to the CPU 1, and the RF unit 55 receives a signal indicating that the connection with the communication partner has failed. When transmitted to the unit 54, the transmission / reception signal processing circuit unit 54 outputs a character string signal such as “fail” to the CPU 1.

  Next, FIG. 18 is a block diagram showing a power control system in the electronic camera 31 of the third embodiment.

  The configuration of the power supply control system of the electronic camera 31 is such that a main power supply 53 that supplies power to the entire electronic camera 31 and power is always supplied to some circuits of the electronic camera 31 by an auxiliary power supply line. The auxiliary power source 57 is used.

  The auxiliary power source 57 is connected to a transmission / reception signal processing circuit unit 54, an RF unit 55, and a key input unit 7 (operation means).

  The main power supply 53 and the transmission / reception signal processing circuit section 54 are connected by a power supply control line 71 via an OR element 69. The main power supply 53 and a power key (POWER key 58; see FIG. 19 described later) which is a main power switch of the key input unit 7 are connected to each other by a power switch signal line 70 via an OR element 69. The power key (58) is also connected to the CPU 1 by a power switch signal line.

  As described above, when the electronic camera 31 is set to the incoming call wake-up mode (at this time, the main power supply 53 is in the off state), when the RF unit 55 receives the incoming signal, the electronic camera 31 receives the incoming signal. Thus, the transmission / reception signal processing circuit unit 54 activates the power supply control line 71. Thus, the OR element 69 outputs a power-on signal to the main power supply 53.

  Further, when the power key (58) of the key input unit 7 is pressed by the operator, the power switch signal line 70 becomes active, whereby a power on signal is output from the OR element 69 to the main power source 53. It is like that.

  In this manner, the main power supply 53 is controlled to be turned on / off by the output signal from the OR element 69. When the main power supply 53 is turned on, the CPU 1 and all other circuits of the electronic camera 31 are supplied with power via the main power supply line.

  When the main power supply 53 is turned on by the incoming signal when the incoming call wakeup mode is set, the operation is as follows after the step S65 in the second transmission mode shown in FIG. It operates in the same sequence as the processing.

  Further, in the electronic camera 31 of the third embodiment, as shown in the plan view of the main part of FIG. 19, the power key 58 and the sleep key 59 are used as the key input unit 7 and the key input of the second embodiment described above. It is provided in addition to the part 7.

  The power key 58 is an operation key that activates the power switch signal line 70 by an operator's pressing operation so that the main power supply 53 is turned on. When the operator presses the power key 58 while the main power supply 53 is on, the input signal is received and the power switch signal line 70 becomes inactive, and the main power supply 53 is turned off. It is like that.

  The sleep key 59 is an operation key for setting the incoming call wakeup mode. When the sleep key 59 is pressed by the operator when the electronic camera 31 is in the transmission mode, the input signal is input to the CPU 1, and the CPU 1 controls the transmission / reception signal processing circuit unit 54 in response to the input signal. The incoming wake-up mode is set. In this state, when the operator further presses the power key 58 to turn off the power, the CPU 1 starts monitoring the incoming signal, and the transmission / reception signal processing circuit unit 54 receives the incoming signal from the RF unit 55. The signal is on standby.

  When the RF unit 55 receives the incoming signal, as described above, the main power supply 53 is automatically turned on, and the subsequent transmission mode processing (processing after step S65 in FIG. 16). Is supposed to run. In addition, the recording medium unit 52 provided in the third embodiment may be a PC card or a flash memory.

  In the third embodiment configured as described above, by incorporating the RF unit 55 in the electronic camera 31, an electronic camera capable of performing data communication using public telephone line radio waves is obtained. be able to.

  FIG. 20 is a block diagram showing an electronic camera according to the fourth embodiment of the present invention. The fourth embodiment has basically the same configuration as the first and second embodiments described above, but in the fourth embodiment, an audio signal processing unit 60, an audio memory 61, A speaker output unit 62, a microphone input unit 63, an audio line input terminal 64, an audio line output terminal 65, etc. are additionally provided, and an electronic camera records and reproduces an audio signal in addition to a video signal such as image data. It is something that can be done.

  That is, the transmission / reception signal processing circuit unit 54 is connected with an audio signal processing unit 60 for performing various processing on the audio signal by an audio signal line, and the audio signal processing unit 60 has an audio as a work memory. The memory 61 is similarly connected by an audio signal line.

  The audio signal processing unit 60 includes a microphone input unit 63 and an audio line input terminal 64 which are audio input units and an audio input unit for inputting an audio signal from the outside. A speaker output unit 62 and an audio line output terminal 65, which are audio output units and an audio output unit for outputting processed audio signals, are connected.

  Only the audio signal of the data signal including the audio signal transmitted from the communication partner, received by the RF unit 55, and input to the transmission / reception signal processing circuit unit 54 is transmitted to the audio signal processing unit 60. Input from the processing circuit unit 54. Since the audio signal is an encoded signal, the audio signal processing unit 60 decodes the audio signal, and the decoded audio signal is converted into an analog signal. The audio signal (analog) is output from the speaker output unit 62 or the audio line output terminal 65 to the outside.

  Further, an audio signal can be directly input to the audio signal processing unit 60 from the microphone input unit 63 or the audio line input terminal 64. Since the audio signal input here is an analog signal, signal processing is performed by the audio signal processing unit 60 so that the audio signal processing unit 60 is in an optimum form when recording on the recording medium unit 52.

  That is, the audio signal input to the audio signal processing unit 60 by the microphone input unit 63, the audio line input terminal 64, and the like is converted into a digital signal and encoded by the audio signal processing unit 60. The encoded audio signal is output to the transmission / reception signal processing circuit unit 54, is output to the recording medium unit 52 as recording means via the system bus 2, and is stored therein.

  The audio signal processing unit 60 is controlled by the transmission / reception signal processing circuit unit 54 (transmission / reception signal processing unit), reads out the audio signal recorded in the recording medium unit 52 (recording unit), and outputs the audio signal to the speaker output unit. 62 and the audio line output terminal 65 (audio output means) are processed into signals in a form suitable for output, and the audio signal input by the microphone input unit 63 and the audio line input terminal 64 (audio input means) is processed. It serves to process signals in a form suitable for recording or playback.

  In the audio signal processing unit 60, when the audio signal is processed, the audio memory 61 is used as a work memory, and the audio signal processing is efficiently performed. .

  Further, in the electronic camera 31 of the fourth embodiment, as shown in the plan view of the main part of FIG. 21, the voice trigger key 66 which is voice recording instruction means as the key input unit 7 is provided in the third embodiment described above. In addition to the above. The voice trigger key 66 is an operation key that is operated when the electronic camera 31 records or reproduces a voice signal.

  Next, the operation of the electronic camera of the fourth embodiment will be described below with reference to the flowcharts of FIGS. The electronic camera 31 of the fourth embodiment has a “videophone mode” using an audio signal in addition to the normal “recording mode”, “playback mode”, and “transmission mode”. A desired operation mode is selected by the operator sequentially pressing the MODE key 42.

  FIG. 22 is a flowchart showing a detection sequence for detecting an operation mode in the electronic camera.

  First, in steps S71 to S74, the operation mode is determined. That is, an input signal from the MODE key 42 corresponding to the operation mode selected by the operator using the MODE key 42 is detected.

  In step S71, it is determined whether a recording mode has been selected. If it is determined that the recording mode is selected, the process proceeds to the recording mode sequence. If the recording mode is not selected, the process proceeds to the next step S72.

  In step S72, it is determined whether or not the playback mode has been selected. If it is determined that the playback mode has been selected, the process proceeds to the playback mode sequence. If the playback mode has not been selected, the process proceeds to the next step S73.

  In step S73, it is determined whether a transmission mode has been selected. Here, if it is determined that the transmission mode is selected, the process proceeds to the data transmission mode sequence. If the transmission mode is not selected, the process proceeds to the next step S74.

  In step S74, it is determined whether the videophone mode has been selected. If it is determined that the videophone mode has been selected, the videophone mode is entered. If the videophone mode is not selected, it is determined that the MODE key 42 has not been operated, and the operation mode is selected. The process returns to the initial state of the determination sequence, and the processes after step S71 are repeated until one of the operation modes is selected by the operator.

  FIG. 23 is a flowchart of a data transmission mode in this electronic camera.

First, in step S75, the CPU 1 monitors whether the RF unit 55 has received an incoming signal, that is, a character string signal such as “RING” or “CALL” from the transmission / reception signal processing circuit unit 54. Here, when the incoming signal is detected, the process proceeds to the second data transmission mode (similar to the flowchart of FIG. 16), and when the incoming signal is not detected, the process proceeds to the next step S76.

  In step S76, an input signal from the character selection key 44 is detected. Here, even when the character selection key 44 is operated by the operator (phone number input operation is performed) and an input signal from the character selection key 44 is detected, the second data transmission mode (FIG. If the input signal from the character selection key 44 is not detected, that is, if the character selection key 44 is not operated, the process proceeds to the next step S77.

  In step S77, an input signal from the function key 41 is detected. When the function key 41 is operated by the operator and an input signal from the function key 41 is detected, the billing information display mode (see the description of FIG. 10) is entered.

  If the input signal from the function key 41 is not detected in step S77 described above, that is, if the function key 41 is not operated, the processing returns to the processing in step S71 described above (reference D in FIG. 22). ) And subsequent processes are repeated.

  When the billing information display mode ends, the process proceeds to the next step S78, where it is confirmed whether or not the function key 41 has been operated again. Here, when an input signal from the function key 41 is detected, the mode shifts to a password setting mode (refer to the description of FIGS. 14 and 15), and after the password setting mode is terminated, the process returns to the above-described step S71. (Symbol D in FIG. 22), the subsequent processing is repeated.

  If an input signal from the function key 41 is not detected, the process immediately returns to the process of step S71 (symbol D in FIG. 22), and the subsequent processes are repeated.

  FIG. 24 is a flowchart of the recording mode in this electronic camera.

  First, in step S81, the CPU 1 detects an input signal from the video trigger key 40. If an input signal from the video trigger key 40 is detected, it is determined that the video trigger key 40 has been operated by the operator, and the process proceeds to step S85. In step S85, the video signal (still image) is detected. ) Is performed, the process returns to the above-described step S71 (symbol D in FIG. 22), and the subsequent processes are repeated.

  If the input signal from the video trigger key 40 is not detected in step S81 described above, it is determined that the video trigger key 40 has not been operated by the operator, and the process proceeds to the next step S82.

  In step S <b> 82, the CPU 1 detects an input signal from the voice trigger key 66. If an input signal from the voice trigger key 66 is detected, it is determined that the voice trigger key 66 has been operated by the operator, and the process proceeds to the next step S86.

  In step S86, a sound signal collecting operation is started. First, upon receiving an input signal from the voice trigger key 66, the CPU 1 sends a sound collection command to the transmission / reception signal processing circuit unit 54. In response to this, the transmission / reception signal processing circuit unit 54 controls the audio signal processing unit 60, and a sound collecting operation is performed by the microphone input unit 63 or the audio line input terminal 64, and the collected audio signal is processed by the audio signal processing. Input to the unit 60. As described above, the audio signal processing unit 60 converts the input audio signal into a digital signal and encodes it. The encoded audio signal (digital) is output to the transmission / reception signal processing circuit unit 54, and is output to the CPU 1 through the signal transmission / reception signal processing circuit 54. Further, the CPU 1 transmits the audio signal to the RAM 4 via the system bus 2. Is temporarily stored here.

  During the sound collecting operation, the CPU 1 monitors the input signal from the voice trigger key 66 (step S87), and after the input signal of the voice trigger key 66 in step S82 described above, the voice trigger key 66 is operated again. When the input signal is detected, or until a predetermined time elapses (step S88 in which timeout is determined), the operation is continued.

  Then, when the input signal of the voice trigger key 66 in step S87 is detected, the sound collecting operation is finished, and the process proceeds to the next step S89. Further, in step S87 described above, the input signal to the voice trigger key 66 is not detected, and the process proceeds to step S88. When it is determined that a predetermined time has elapsed and timed out, the sound collecting operation is terminated. Similarly, the process proceeds to the next step S89.

  In step S89, the CPU 1 reads the audio signal (digital) temporarily stored in the RAM 4 during the above-described sound collection operation, outputs it to the recording medium unit 52 via the system bus 2, and writes it as an audio data file. Do. And it returns to the process of the above-mentioned step S71 (symbol D of Drawing 22), and the subsequent processes are repeated.

  On the other hand, if the input signal from the voice trigger key 66 is not detected in step S82 described above, it is determined that the voice trigger key 66 has not been operated by the operator, and the process proceeds to the next step S83.

  In step S83, the CPU 1 detects an input signal from the function key 41. If the input signal from the function key 41 is detected, the process proceeds to the next step S84. If the input signal from the function key 41 is not detected, the process returns to the above-described step S71 ( The subsequent processing is repeated as indicated by reference numeral D) in FIG.

  In step S84, the operator can set a voice timeout time. The voice time-out time is set using the character selection key 44 and the ENTER key 43. The setting procedure is the same as the telephone number input operation described above (see FIGS. 10 and 11).

  Then, after the setting of the audio timeout time is completed, the process returns to the above-described step S71 (symbol D in FIG. 22), and the subsequent processes are repeated.

  Note that the time-out of the sound collection operation in step S88 described above is determined based on the time set here. This timeout setting time is also used during audio data transmission operation during videophone mode execution described later (see steps S97 to S104 in FIG. 25).

  FIG. 25 is a flowchart of the videophone mode of this electronic camera.

  First, in step S90, the CPU 1 monitors an input signal from the character selection key 44. If the input signal from the character selection key 44 is not detected, the process proceeds to the next step S95, and the incoming signal from the RF unit 55 is monitored in this step S95. If no incoming signal is detected, the process returns to the above-described step S74 (symbol E in FIG. 22), and the subsequent processes are repeated. If an incoming signal is detected, it is determined that an incoming call is received, and the process proceeds to step S96.

  On the other hand, when the input signal from the character selection key 44 is detected in step S90 described above and the operator has operated the character selection key 44 to perform a telephone number input operation, the next step S91 is performed. Proceed to the process.

  In step S91, the operator performs a telephone number input operation using the character selection key 44 and the ENTER key 43. Subsequently, in the next step S92, the video trigger key 40 is pressed, and thereby the input telephone number is displayed. A transmission command is transmitted to the CPU 1.

  In response, CPU 1 performs a password check in step S93. As a result of the password check, if the password unique to the SIM 9 matches the password preset and registered in the electronic camera 31, the process proceeds to the next step S94, and if the two passwords do not match, Returning to the process of step S71 described above (symbol D in FIG. 22), the subsequent processes are repeated.

  In step S94, the CPU 1 transmits the telephone number information and the transmission command input in step S92 described above to the transmission / reception signal processing circuit unit 54. Thereby, the transmission / reception signal processing circuit unit 54 controls the RF unit 55 to perform a transmission operation. Then, the process proceeds to the next step S96.

  In step S96, it is determined whether or not the connection with the communication partner is successful. Here, when a character string signal such as “fail” is transmitted from the transmission / reception signal processing circuit unit 54 to the CPU 1, the CPU 1 determines that the connection with the communication partner has failed, and in the above-described step S 71. Returning to the processing (symbol D in FIG. 22), the subsequent processing is repeated.

  On the other hand, when a character string signal such as “connect” is transmitted from the transmission / reception signal processing circuit unit 54 to the CPU 1 in step S96 described above, the CPU 1 determines that the connection with the communication partner is successful, Proceeding to the next step S97, and in this step S97, voice signal data transmission with the communication partner is enabled (calling state), and voice data transmission operation is performed.

  Note that the voice data transmission operation performed here is an operation of converting voice information in a normal telephone call state, that is, voice information by conversation with a communication partner into an electrical voice signal and transmitting it.

  That is, an encoded audio signal transmitted from a communication partner via a telephone line is received by the RF unit 55, input to the transmission / reception signal processing circuit unit 54, and further input to the audio signal processing unit 60. . In the audio signal processing unit 60, the audio signal is decoded and converted into an analog signal, and is output to the outside from the speaker output unit 62 or the audio line output terminal 65.

  At the same time, the audio signal (analog) input from the microphone input unit 63 or the audio line input terminal 64 is converted into a digital signal and encoded by the audio signal processing unit 60 and sent to the transmission / reception signal processing circuit unit 54. Is output and transmitted to the communication partner by the RF unit 55.

  Further, in the audio data transmission (call) state in step S97, the subject image continuously formed by the photographing optical system 48 passes through the CCD 32, the process processing unit 33, and the A / D converter 34, and the image data image. It is converted into a signal (digital) and sequentially stored in the frame memory 36. At the same time, the video signal stored in the frame memory 36 is repeatedly read out by the D / A converter 35, and an analog signal (video Signal) and sequentially output from the video signal output terminal 39 to the external display device. The output form of the video signal at this time is a through image output in which the video signal is sequentially and continuously reproduced.

  Further, in the above-described audio data transmission (call) state, the CPU 1 monitors input signals from the video trigger key 40, the audio trigger key 66, and the MODE key 42 (steps S98, S100, S105).

  Therefore, if the operator operates the video trigger key 40 during the voice data transmission (call) operation, the process proceeds to step S99, and the video signal data transmission operation is interrupted.

  That is, when the CPU 1 detects an input signal from the video trigger key 40 in step S98 described above, the audio data transmission and the image reproduction from the video signal output terminal 39 are interrupted. At the same time, among the video signals stored in the frame memory 36, a predetermined video signal (still image) at the time when the video trigger key 40 is operated is output to the companding circuit unit 38 via the video bus 51. Here, after being subjected to compression processing, it is output to the transmission / reception signal processing circuit unit 54 via the system bus 2. The transmission / reception signal processing circuit unit 54 controls the RF unit 55 to transmit the predetermined video signal to the communication partner. When the data transmission of the video signal is completed, the process returns to the above-described step S97, and the interrupted audio data transmission operation and the image reproduction from the video signal output terminal 39 are resumed.

  If the operator operates the audio trigger key 66 without operating the video trigger key 40 during the audio data transmission (call) operation in step S97 described above, the process proceeds to the next step S101.

  In step S <b> 101, the CPU 1 controls the transmission / reception signal processing circuit unit 54 to start a call voice collecting operation. That is, the encoded audio signal from the communication partner received by the RF unit 55 is output to the CPU 1 via the transmission / reception signal processing circuit unit 54 and the system bus 2, and the CPU 1 sequentially sends this audio signal to the RAM 4. Store. At the same time, an audio signal input from the microphone input unit 63 or the audio line input terminal 64 is also output to the CPU 1 via the audio signal processing unit 60, the transmission / reception signal processing circuit unit 54, and the system bus 2, and the CPU 1 The signals are sequentially stored in the RAM 4.

  Even during the sound collection operation, the CPU 1 continues to monitor the input signal from the sound trigger key 66 and also monitors the elapsed time of the sound collection operation (steps S102 and S103).

  Therefore, when the voice trigger key 66 is operated by the operator during the sound collection operation or when a predetermined time has elapsed (timeout is determined), the processing in the next step S104 is performed. move on.

  Here, as the predetermined time for determining the timeout, the timeout time set by the operator in the above-described step S84 (see FIG. 24) is used.

  In step S104, the CPU 1 reads the encoded audio signal stored in the RAM 4, records it as an audio data file in the recording medium unit 52, returns to the processing in step S97 described above, and performs the subsequent processing, ie, audio data. Repeat the transmission operation.

  Furthermore, if the operator does not operate the video trigger key 40 or the voice trigger key 66 during the voice data transmission (call) operation in step S97 described above, the input signal from the MODE key 42 is determined in step S105. Monitoring is performed. If the CPU 1 does not detect an input signal from the MODE key 42, the process proceeds to step S106. In step S106, the CPU 1 transmits / receives a line disconnection signal from the communication partner, for example, It monitors whether or not a character string signal such as “NO CARRIER” has been received.

  Here, when a line disconnection signal is detected, that is, when the RF unit 55 receives a line disconnection signal from a communication partner and this signal is transmitted to the CPU 1 via the transmission / reception signal processing circuit unit 54, The process proceeds to step S108. On the other hand, if the CPU 1 does not detect a line disconnection signal, the process returns to the above-described step S97 and the subsequent processes are repeated.

  If the input signal from the MODE key 42 is detected in step S105 described above, the process proceeds to step S107. In step S107, the CPU 1 controls the transmission / reception signal processing circuit unit 54 to disconnect the line. The operation is performed, and the process proceeds to the next step S108.

  In step S108, billing information and the like regarding the communication usage fee just made from the line network is acquired, and based on the acquired billing information and the like, for example, date information, usage time information, destination telephone number information, billing information (usage information) Detailed information such as (charge information) is created and recorded in the SIM 9 (step S109). Then, the detailed information is displayed on the display unit 8 (step S110), the process returns to the above-described step S71 (symbol D in FIG. 22), and the subsequent processes are repeated.

  As described above, when the line disconnection signal from the communication partner is detected in step S106, after the processing from step S108 to S110 is performed, the processing from step S71 described above is repeated. At this time, if the operator does not operate the MODE key 42, the operation mode is not changed, so that the videophone mode is entered again. Therefore, the input signal from the character selection key 44 by the operator or the waiting state for the incoming signal is set.

  As described above, according to the fourth embodiment, by further adding a function for processing audio data, it is possible to easily transmit audio data together with image data.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications and applications can be made without departing from the spirit of the invention.
