FIG. 5 is a flowchart showing an operation process of the portable communication device 1.
When predetermined information is given to the main body connection unit 24, the process proceeds from step s0 to step s1, and operation processing is started. The external connection unit 41 of the external connection device 40 is detachably connected to the main unit connection unit 24, and the operation switch 44a of the external command input unit 44 is operated, specifically, pressed down to the main unit connection unit. Predetermined information is given. When the operation switch 44a is pressed for a predetermined time T or longer, the control unit 11 determines that predetermined information has been input. The predetermined time T is selected to be 1 second, for example. As described above, if the controller 11 is not pressed for a predetermined time or more, the control unit 11 does not determine that predetermined information has been input. Therefore, when the operation switch 44a is undesirably pressed, it is prevented from malfunctioning. Is done. The predetermined time may be 1 second or less. In this case, the time until the control unit 11 reacts can be shortened, and the operability is improved.

  For example, a predetermined potential is applied to the connector terminal of the main body connection unit 24 to which the external command input unit 44 is connected. By connecting the external connection portion 41, an energization path including the connector terminal, the conductive wire, the operation switch 44a, and the ground terminal is formed. When the switching mode of the operation switch 44a is changed, the external command input portion 44 is connected. The potential of the connected connector terminal changes. The control unit 11 detects a change in the potential of the connector terminal and determines whether or not predetermined information is given.

  The operator can give predetermined command information to the control unit 11 by operating the operation switch 44 a of the external command input unit 44.

  Next, in step s1, the control unit 11 determines whether communication is in progress. Specifically, the control unit 11 communicates with another communication device and determines whether or not the radio unit 20 is controlled to transmit and receive audio information. If it is determined in step s1 that the control unit 11 is not communicating, that is, if it is determined that the wireless unit 20 is controlled to stop communication with another communication device, the process proceeds to step s2.

  In step s2, the control unit 11 determines whether or not a call is being received. Specifically, the control unit 11 determines whether or not the wireless unit 20 has received a communication request. If it is determined in step s2 that the control unit 11 is not receiving a call, that is, if it is determined that the wireless unit 20 has not received a communication request, the process proceeds to step s3.

  In step s3, the control unit 11 determines whether or not the camera-related unit is operating. When the camera-related unit is operating, the control unit 11 controls the imaging unit 8 to generate the image information, and the second memory 10 is stored so as to store the image information generated by the imaging unit. Including the controlled state. If the control unit 11 determines in step s3 that the camera-related unit is operating, the process proceeds to step s4.

  In step s4, the control unit 11 determines whether or not the release setting is valid. Specifically, the control unit 11 determines whether the release setting is in an effective state based on the release setting information stored in the second memory 10. If the control unit 11 determines in step s4 that the release setting is valid, the process proceeds to step s5.

  In step s5, the control unit 11 determines whether image information can be stored, in other words, whether the shutter can be released. Specifically, the control unit 11 determines whether image data generated by the imaging unit 8 can be stored. If the control unit 11 determines in step s5 that image information can be stored, the process proceeds to step s6. In step a5, for example, by determining whether or not the storage capacity that can be stored in the second memory 10 is greater than or equal to a predetermined capacity, the storage capacity that can be stored in the second memory 10 is greater than or equal to the predetermined capacity. If so, the process proceeds to step a6.

  In step s6, the control unit 11 stores the image data generated by the imaging unit 8 as a still image in the second memory 10, and based on the output selection information stored in the second memory 10, the second memory The audio processing unit 21 is controlled so that predetermined audio information indicating that it is stored in the main unit audio output unit 23 or the main unit connection unit 24 is given. When the process of step s6 is completed, the process proceeds to step s7 and the process is terminated.

  As described above, in the communication device 1 of the present invention, the image data generated by the imaging unit 8 can be stored in the second memory 10 by operating the external command input unit 44 of the external connection device 40. Since the external audio output unit 42, the external audio input unit 43, and the external connection unit 41 of the external connection device 40 are movable relative to the external connection unit 41, the user operates the external command input unit 44. Even so, the force when the user operates the external command input unit 44 is not transmitted to the portable communication device 1. Therefore, when predetermined information is input through the external command input unit 44, the external command input unit 44 can function as a release button, and image information with improved image quality free from camera shake can be stored in the second memory 10. Can do.

  Further, when output selection information representing the main body audio output unit 23 is stored in the second memory 10 described above, the control unit 11 is an audio indicating that image information is stored in the second memory 10 from the main body audio output unit 23. The voice processing unit 21 is controlled to output information. When the output selection information indicating the main body connection unit is stored in the second memory 10, the control unit 11 gives the main body connection unit 24 audio information indicating that the image information is stored in the second memory 10. The voice processing unit 21 is controlled. When output selection information representing both the main body audio output unit 23 and the main body connection unit 24 is selected in the second memory 10, audio information indicating that image information is stored in the second memory 10 from the main body audio output unit is displayed. The audio processing unit 21 is controlled to output the audio information indicating that the image information is stored in the second memory 10 to the main body connection unit. Whether the audio information indicating that the image information is stored in the second memory 10 is output from the main body audio output unit 23 and the external audio output unit 42 of the external connection device 40 can be selected by the output selection unit by the output selection unit. Since the location where the audio information is output can be changed according to the usage situation, the convenience is improved.

  If it is determined in step s1 that the control unit 11 is communicating, that is, if it is determined that the wireless unit 20 is controlled to communicate with another communication device, the process proceeds to step s8. In step s8, the control unit 11 controls the radio unit 20 to stop transmission and reception of audio information, that is, stop communication, and then proceeds to step s7 to end the process. As described above, when the wireless unit 20 is communicating with another communication device, the communication can be easily stopped only by giving predetermined command information to the main body connection unit 24.

  If it is determined in step s2 that the control unit is receiving a call, that is, if the wireless unit 20 is receiving a communication request, the process proceeds to step s9. In step s9, the control unit 11 controls the wireless unit 20 to perform transmission / reception of audio information, and provides the audio information received by the radio unit 20 to at least the main body connection unit 24 and is supplied to the main body connection unit 24. The wireless unit 20 is controlled to transmit the audio information, the process proceeds to step s7, and the process ends. As described above, when the wireless unit 20 receives a communication request, simply sending predetermined command information from the external device 40 to the main body connection unit 24, easily transmitting voice information to other communication devices, and other Audio information can be received from the other communication device, that is, a call can be made, and convenience is improved.

  If it is determined in step s3 described above that the camera-related unit is not operating, the process proceeds to step 10. In step s10, control unit 11 determines whether or not earphone transmission is possible. Specifically, based on the earphone transmission setting information stored in the second memory 10, the control unit 11 determines whether or not the earphone transmission is valid and predetermined notification destination information is stored. In step s10, if the control unit 11 determines that the earphone transmission is possible, that is, if the earphone transmission is valid and the predetermined notification destination information is stored in the second memory 10, the process proceeds to step s11. Move.

  In step s11, the control unit 11 controls the radio unit 20 to place a call to predetermined notification destination information, moves to step s7, and ends the process. In this way, simply by giving predetermined command information to the external connection unit 41, a call can be made to another communication device corresponding to the predetermined notification destination information stored in the second memory 10, and the other communication device Because it is possible to easily communicate with each other, convenience is improved.

  If the control unit 11 determines in step s4 described above that the release setting is not valid, the process proceeds to step s10.

  In step s10 described above, the control unit 11 determines that the earphone transmission is not possible, that is, determines that the earphone transmission is not valid or that predetermined notification destination information is not stored in the second memory 10. Then, it moves to step s7 and complete | finishes a process.

  In the portable communication device 1, when the wireless unit 20 is communicating, the image information generated by the imaging unit 8 is stored in the second memory 10 even if predetermined information is given to the main body connection unit 24. It is prevented. Therefore, when communicating with other communication devices, it is possible to prevent the predetermined information from being input from the external command input unit 44 and storing the generated image information in the second memory 10 undesirably. The In addition, when image information is generated by the imaging unit 8, if predetermined information is given to the main body connection unit 24, the image information generated by the imaging unit 8 is stored in the second memory 10. Can be shortened in the processing time until it is stored in the second memory 10.

  If the control unit 11 determines in step s5 described above that image information cannot be stored, the process proceeds to step s6.

  The control unit 11 may store the image data generated by the image processing unit 7 in the second memory 10 after the image data generated by the imaging unit 8 is encoded and may be stored in the second memory 10. Thereafter, the image data may be read from the second memory 10, encoded, and stored again in the second memory 10. The control unit 11 encodes the image data stored in the second memory 10 using, for example, a JPEG (Joint Photographic Experts Group) method, and stores the image data in the second memory 10 in a predetermined data format. The predetermined data format is, for example, DPOF (Digital Print Order Format). DPOF includes information such as JPEG data and the creation date and time of the JPEG data. By storing in such a data format, image information can be printed directly in a printing apparatus such as a printer. For example, the image information is read by a personal computer and then printed by the printing apparatus. Compared to the case, the trouble of printing the image information can be simplified.

  Further, in the portable communication device 1, when the release setting is set to invalid, the external command input unit 44 does not function as a shutter key. Therefore, the external command input unit 44 is generated by the imaging unit 8 when it is operated undesirably. Image information can be prevented from being stored in the second memory 10.

  The portable communication device 1 described above has a recording function. When command information to be recorded is input from either one of the first and second operation units 2 and 3, the control unit 11 controls the audio processing unit 21 and the second memory 10 to give to the audio processing unit. The audio information is subjected to a predetermined process and stored in the second memory 10. The predetermined processing is audio information compression processing. Based on the input selection information stored in the second memory 10, the control unit 11 causes the second memory 10 to store audio data provided from at least one of the main body audio input unit 22 and the main body connection unit 24. Whether the audio information stored in the second memory 10 is input from the main body audio input unit 22, the external audio input unit 43 of the external connection device 40, or both is input according to the use situation. Therefore, the convenience can be improved.

  The portable communication device 1 described above has a moving image shooting function. When command information for capturing a moving image is input from either one of the first and second operation units 2 and 3, the control unit 11 controls the imaging unit 8, the audio processing unit 21, and the second memory 10. The image information generated by the imaging unit 8 and the audio information given to the audio processing unit are subjected to predetermined processing and stored in the second memory 10. The predetermined process is a compression process of image information and audio information. The image information compression method is realized by, for example, MPEG (Motion Picture Experts Group) 2. The control unit 11 may store the image information in the second memory 10 and then read the image information from the second memory 10 and perform compression processing.

  In another embodiment of the present invention, in step s6 of the flowchart shown in FIG. 5 described above, the image information generated by the imaging unit 8 is stored as a still image in the first memory 9, and the first and second images are stored. When the information for saving is input by the operation units 2 and 3, the still image stored in the first memory 9 may be stored in the second memory 10.

  In the above-described external connection device 40, the conducting wire to which the audio information is transmitted and the conducting wire to which the predetermined information is transmitted are realized by one conducting wire, and the predetermined command information and the audio information are transmitted through the same conducting wire. May be. In this case, the connector terminal of the main body connection part 24 of the portable communication device 1 can be configured to be small. Even with such a configuration, the same effects as those of the above-described embodiment can be obtained.
