Description

1245551 06283pif 2. doc / 012 发明 Description of the invention: The present invention relates to a portable information terminal, such as a portable mobile phone with a headphone jack for sound input and output, PHS (personal handy-phone system), PDA ( A personal digital assistant, a digital camera for a portable information terminal, including a portable digital camera / information terminal system for an information terminal and a digital camera, and a method for controlling a portable information terminal. In recent years, with the increase in the speed of data communication using portable information terminals and the significant progress achieved in information and communication technology, portable telephones have shifted from the use of telephones to integrated information tools that are quickly received. In this trend, customers need to expand from basic information such as video, music, and mail to high-end content such as mobile images and programs, and expect to develop more applications in the future. In response to these customer needs, machines called information sales machines have begun to appear on the market to provide not only sales services for sound data information, but also various other types of information that can be accessed through special cables. The portable information terminal is connected to the information selling machine. When receiving information from the information selling machine through a special cable, it is necessary to insert the connector of the cable into the inside of the portable terminal, but the inconvenient problem is that because it is connected to the front side and the back side to ensure the connection in the correct direction, The user must confirm the inconvenience of the front and rear of the connector. At the same time, when connected to a portable terminal, the locking mechanism of the connector operates, and the connection becomes locked, but if the user wants to unplug the connector without being aware of the locked state, the connector may Subject to over negative _ 1245551 06283pif2. doc / 012. Similarly, when a portable telephone and PHS are used as a mobile computing communication device, a PC card is used as an interface. Therefore, when a user travels, a PC card and a connection cable must be carried, which causes another inconvenience. Similarly, some computers only have a PCMCIA (Personal Computer Memory Card International) slot for inserting a PC card, so that when this slot is occupied by a portable phone, other devices cannot be connected, which causes another inconvenience Sex. Even if 'it is necessary to use some peripheral keys, the PC card inserted in the PCMCIA slot must be replaced with another card, causing a problem of wasting time. At the same time, in response to the need to use a digital camera to a portable terminal to transfer the image recorded in the digital camera to another terminal, the Japanese patent application, the first public version, Hei 10-341302 and Hei 1 1-08823 are disclosed Band-based connection technologies, such as IRDA (Infrared Data Access) or RS-232C, connect digital cameras to portable terminals to transfer data. However, the use of cables such as IRDA or RS-232C to transfer image data is problematic in terms of handling and portability. Similarly, traditional digital cameras are expected to be connected to various portable communication terminals, such as portable telephone terminals, PHS, PDA, mobile personal computers, so that even display areas and operating areas such as LCD monitors are provided in portable terminals. Onboard, it is usually also provided with digital cameras, and the processing becomes complicated, and the cost of the combined system increases. At the same time, the digital camera itself must have a power source and the size of the casing is increased because it cannot supply power from the device connected to the digital camera, which causes a problem that it is not suitable for portable devices. As mentioned above, in the past, it was difficult to avoid the complexity of the digital camera structure and realize a highly convenient digital camera. 1245551 06283pif 2. doc / 012 When asked ’The image data is transmitted in series according to the EIA (Electronic Industry Association) standard, but]: rda and RS-232C and others always require special interfaces. At the same time, in addition to the data transmission method using the above-mentioned cable, the Japanese Patent Application, the first published version, Hei 06_268582 discloses that data is transmitted through a medium such as a memory card, but even with this technology, the interface circuit and drive circuit are still necessary . For this reason, when connecting a digital camera to a portable communication terminal, expensive parts and interfaces were required in the past. The problem is that it is difficult to reduce the size of the digital camera and the portable terminal 'or reduce the cost of the integrated system. Even 'When using the RS_232C mentioned above, serial communication according to the EIA RS-232C standard is used, but in normal serial communication, it is necessary to start communication before starting' by exchanging some between the portable terminal and the digital camera. The command to perform operations such as, exchange operation, and so on can make the image data transmitted only after confirming that both parties are in the operating state, resulting in the image data transmission cannot be rapid. At the same time, in serial communication, the information that distinguishes the start and end of individual data is attached to the data of each byte, so that when the 2 bits of this 8-bit are used as the purpose of differentiation, 1 byte Only six bits of information can be carried, resulting in the data itself cannot be processed efficiently. In addition to this problem, "Although parallel communication is known to increase the transmission speed by increasing the number of serial lines," parallel data transmission technology is not good because the number of signal lines must be increased. For example, small size, light weight and low cost are required. In the case of a connection terminal of a device such as a digital camera and a portable communication terminal, it increases the system cost. Sameday Temple ’When recording images with a digital camera, the user must perform 1245551 06283pif2. doc / 012 Certain operations, such as: operating the keys on the operating area of a portable terminal and confirming the settings on the shadow area of the final machine to select the image recording mode; press the define key to define the image Recording mode; then record images in image recording mode. Even when the portable terminal is a portable telephone, for example, it is necessary to operate at least two keys, one of which changes from the sound mode of the phone function to the image recording mode of the digital camera, and the other button defines the action in the selected mode . Furthermore, it is necessary to provide operation buttons for image recording, for example, buttons acting as shutter buttons, and setting buttons to specify recording conditions, and the like. Therefore, the number of keys to be operated is increased, such as switching to the recording mode and operating the digital camera. The problem is that when the user is ready to record the pattern, it takes some time to operate when the defined recording mode is reached. button. In addition, in order to define the image recording mode, it is necessary to select the image recording mode first, and then operate the definition key, so that the user needs to watch the display area of the portable terminal when operating the keys to define the parameters of the image recording mode, so that the problem is not only Complicated key operations are a missed opportunity to record good images.

FIG. 1 shows a digital camera for a portable information terminal (hereinafter referred to as a digital camera only), 1A-1D is a front view and a side view of the digital camera used in the portable information terminal in Example 1-1, respectively. Bottom view and perspective view. FIG. 2 shows an exploded perspective view of the digital camera in this embodiment. 33 1245551 06283pif2.doc / 012 Digital camera 1 includes: top cover 2; infrared absorption filter 3, lens beam 4 constituting the lens system of the digital camera; positioning lens beam 4 and blocking from the outside of the optical axis to the imaging element Bracket 5; Reflective Resistive Film 6 to limit uncomfortable reflected light; CM0S-IC7 for processing imaging elements and image data; Substrate 8 for CM0S-IC7 and other electronic parts; and bottom cover 9. The bottom surfaces of the top cover 2 and the bottom cover 9 are provided with semicircular cut-off regions 2a, 9a. Behind each of the cut-off areas 2a, 9a, support plates 2b, 9b are provided, and each cut-off area further includes each of the support plates 2b, 9b including a cutout. Here, CMOS-IC7 can be replaced by contact point D-iC. The plug 10 is inserted between the circuit breakers 9a and 9b of the bottom cover 9 by inserting the bottom area of the base area 10a of the plug 10, and the combination part 2-8 is placed on the top cover 2 and inserted into the bottom part 10a. The top area is between the current interrupter 2a and the support plate 2b, and is attached to the digital camera body. The arrangement sequence in the plug 10 is from the base area 10a side, the contact point 11a of the power source, the contact point lib of the ground point, the contact point 11c of the clock signal, and the contact point lid for transmitting data. The top cover 2 and the bottom cover 9 are fixed by screws (not shown). This structure can also be fixed without screws. The central axis 10b of the plug 10 is oriented so as to make a right angle to the optical axis of the lens (optical axis of the lens pass). The mounting area 12 serves as a part of the upper and lower covers surrounding the plug 10. The mounting region 12 is a portion protruding from the bottom surface of the periphery of the base region, and preferably has a convex shape so that the amount of protrusion gradually decreases from the top to the periphery of the base region of the plug 10. The light passing through the lens window 2c of the top cover 2 from the image object is incident on the lens beam 4 through the infrared absorption filter 3, and is focused on the imaging element 1245551 06283piO.doc / 012 CMOS-IC7. The imaging signals accumulated in the imaging element are converted into electrical signals, processed in CMOS-IC7, and transmitted to the plug 10. Here, it is assumed that the imaging signal is output after white light balance. Figure 3 explains the connection status of the digital camera. The headphone jack Π is provided on the right side surface 13c of the portable telephone 13. The liquid crystal display area 24 is located on the front side, and the antenna 13b is located on the top surface. By inserting the plug 10 of the digital camera 1 into the headphone socket 11 in the direction shown in FIG. 3, the digital camera 1 is electrically connected to the portable telephone 13 and mechanically fixed. The earphone socket 11 of the connecting plug 10 can rotate the terminal shaft 10b 360 degrees, as shown by the double-headed arrow A, because the two ends are circular. To this end, referring to the front surface of the portable telephone 13 having the display area 13c, the lens window 2c of the digital camera 1 can be rotated to any of the directions A shown in FIG. That is, the optical axis (image recording direction) of the lens of the digital camera 1 at right angles to the plug 10 can be pointed to any direction within a 360-degree rotation range with respect to the liquid crystal display area 24. Similarly, the mounting area 12 on the bottom surface of the digital camera contacts the peripheral side surface of the headphone socket 11 so that this area can slide. Therefore, the protruding distance from the digital camera 1 of the portable telephone 13 can be minimized, and the contact area of the portable telephone 13 can be minimized. Therefore, the size of the overall device can be made quite close, and it is advantageous for the sliding action to change the recording direction of the digital camera 1 in the connection condition of the terminal shaft 10b. Moreover, because the peripheral area la of the mounting area 12 of the digital camera is 35 1245551 06283pif2.doc / 012 on the side surface 13c of the portable phone 13, if the digital camera has a cover of the headphone socket U, the digital camera can not interfere with the headphone socket Rotate under the cover of the 11 so that the cover does not hinder the correct installation of the digital camera. Next, it will be shown in Fig. 4 that the internal circuit structure of the digital camera 1 when the digital camera 1 is connected to the handheld information terminal in the embodiment 1-1. Here, the portable information terminal is represented by a portable telephone (including PHA) in this embodiment. In this figure, the digital camera 1 includes: an imaging area 14; an AD conversion area 15; a signal processing area 16; a buffer memory area 17 and an interface area 18. In this example, the buffer memory area 17 has a capacity for storing one image, and the memory area 20 includes a semiconductor memory, a card, and the like. It should be understood that the image data can be directly output to the handset 13 without being stored in the buffer memory area 17. On the other hand, the portable telephone 13 includes: an interface area 19 for transmitting data to external devices connected through the headphone socket 11; a memory area 20 including ROM and RAM, which contains various programs and fixed data; an antenna (not shown) ); The RF transceiver 21 transmits sound signals and other data to the destination through the base station; the signal processing area 22 is mainly for processing data; the operation area has various keys such as ten key panels; the liquid crystal display area 24, Various data are displayed; the switching area 25 changes the interface area 19 according to the type of external device; and the CPU 26 controls each area by executing a program stored in the memory area 20. The interface area 19 includes an audio interface (I / F) 19a and an image interface (I / F) 19b. The sound interface (I / F) 19a responds to a similar sound signal from an externally connected device such as a headset microphone or a stereo 36 1245551 06283pif2.doc / 012 headset, and converts such a similar signal to be processed inside a portable telephone The digital signal and output the converted data to the signal processing area 22, or convert the digital sound data transmitted from the memory area 20 or the signal processing area 22 into similar data, and output this data to the external device through the headphone socket 11 . On the other hand, when an external device such as the digital camera 1 is connected to the headphone socket 11, the image interface 19b ensures that the data processed by the digital camera 1 and the portable telephone 13 are compatible. That is, the image data input from the headphone socket 11 is converted into data that can be processed by the portable telephone, and the processed data is output to the signal processing area 22, or the digital data transmitted from the signal processing area 22 is converted The data that can be processed by the digital camera 1 is output to the digital camera 1 through the headphone socket 11. The signal processing area 22 is particularly used for digitizing data such as audio data at a high speed. For example, it may include a DSP (Digital Signal Processor). When external devices are connected via headphones, the LCD display area 24 displays various settings of the phone functions of the portable telephone, various forms, and various information related to various external devices (headphones, stereo earphones, etc.). In the same way, ROM is a part of §5 memory, and stores various programs that execute the functions of the phone, control programs and various fixed resources, and the CPU 26 controls the various blocks of the portable phone 13 by executing such programs. Similarly, the RAM (not shown) temporarily stores data processed by the signal processing area 22, data processed by the CPU 26, and various external input data. '' The switching area 25 recognizes the device connected to the headphone jack 11 and switches to an interface suitable for the device being connected. 37 1245551 06283pif2.doc / 012 More specifically, when the switching area 25 detects that the socket is connected to the headphone socket 11, it is determined by detecting the resistance 値 between the second and third contact points on the top of the connecting socket. Device type, and the device type is determined based on this. Below, a special example of connecting the digital camera 1, the headphone microphone and the stereo headphone to the headphone jack 11 will be used to explain the process of identifying the external connection device in the signal processing area 22. Figure 7 shows an example of connecting a headset microphone jack, and Figure 8 shows an example of connecting a stereo headset. The headphone socket in FIG. 7 has four contact points, which include: power contact point 71, ground contact point 72, receiving sound data contact point 73 (headphone contact point) and transmitted sound data contact point 74 (microphone contact Point), and among these four contact points, the electrical resistance between the ground contact point 72 and the receiving sound data contact point 73 is different from the resistance between the ground contact point 72 and the transmitting sound data contact point 74. In contrast, the stereo headset in FIG. 8 has four contact points, including: empty contact point 81, ground contact point 82, receiving stereo (L) sound data contact point 83 (L), and receiving stereo (R) sound The data contact point 84 (R), and among these four contact points, the electrical resistance between the ground contact point 82 and the receiving stereo (L) sound data contact point 83 is the same as the ground contact point 82 and the receiving stereo (R ) Resistance between audio data contact points 84. It should be understood that in the socket of the headset microphone and the stereo headset, the endpoints are not insulated from each other. Similarly, the plug 10 of the digital camera 1 in Figure 2 is connected to the contact point 11c of the transmission clock signal, so that the resistance between these ends is infinite. 38 1245551 06283pif2.doc / 012 Therefore, the switching area 25 detects the resistance 接触 between the contact point-2 and the contact point-3, and if this 値 is infinite, it can be determined that the digital camera 1 is connected, and if this 値 is not Infinite, it is connected to the earphone microphone or stereo headphones, so that it can detect the resistance 値 between the two contact points for comparison. If the detection results show that the resistances are the same, you can decide to connect the device as a stereo headset, and if the resistances are not the same, you can decide to connect the device as an earphone microphone. As described above, when the switching area 25 determines the connected device camera 1, the interface area 19 selects the imaging interface to be related to the image data, so that the data communication between the digital camera 1 and the portable phone 13 through the imaging interface 19b can be performed. Similarly, when the imaging interface 19b is selected, the operation keys (not shown) provided on the operation area 23 of the portable telephone 13 are regarded as the predetermined function keys of the digital camera 1. Here, the image data is processed in series. Moreover, in addition to its ability to automatically detect the connection of the digital camera 1 and select the imaging interface, when the user performs an operation (such as a mode switch), the above-mentioned switching area 25 can recognize that the external device is the digital camera 1. Similarly, in this embodiment, the switching area 25 may also be located on the digital camera 1 side. Fig. 5 shows a flow chart of the process from the preliminary image recording phase to the image information transmission phase. In Fig. 5A, the portable telephone 13 is in a normal operation state (S501). In this state, the plug 10 of the digital camera 1 is inserted and coupled to the headphone jack 1US502). The current state is set to the camera mode (S503). The CPU 26 of the portable phone determines whether to enable the phone operation, and if the phone operation is enabled, the flow returns to S501 (S504). If the phone operation is not enabled by 39 1245551 06283pif2.doc / 012, it is determined whether the phone operation is enabled, and if the phone operation is enabled, the flow returns to S504. If the digital camera 1 is ready to receive image data, the image data is read in (S506). On the other hand, if in FIG. 5B, the digital camera 1 connected to the portable phone is initialized (S512), and the recorded image is processed to output this image data through the plug 10 (S513, S514) to 13 side of portable telephone. Next, this process determines whether the camera mode is off (S515), and if it is off, the process is complete. In S507 in FIG. 5A, the image output from the digital camera 1 is displayed on the liquid crystal screen of the liquid crystal display area 24. Second, this process determines whether the user has performed this operation to store the image (S508), and if there is a storage operation, the image data is transmitted from the digital camera 1 to the portable telephone 13 through the plug 10, the headphone socket 11 and the interface area 19 (S509), and the image data is stored in the RAM stored in the memory area 20 (S510). Secondly, this process determines whether the recorded image data is to be transmitted (S511), and if a transmission operation has been instructed, the processing proceeds to the phone operation in S504, and the image data is transmitted. If the transmission operation is not instructed, the flow returns to the normal operation state in S501. Next, an example of using the digital camera 1 to attach the digital camera 1 to the portable telephone 13 will be explained. Fig. 6A shows that the lens window 2c of the digital camera 1 is oriented toward the recording object 27 relative to the user, and the image is recorded when the user views the image displayed on the liquid crystal display area 24 of the portable telephone 13. In this example, the digital camera 520 is mechanically supported by the handset 13 as a terminal and can be operated by one hand. Similarly, FIG. 6B shows the lens window 2c of the digital camera 1 facing 1245551 06283pif2.doc / 012. The user himself, the portable terminal device is located to the digital camera, and the user views the liquid crystal displayed on the portable phone 13 When the self image on the display area 24 is displayed, the image is recorded. As described above, according to the portable terminal device connected to the digital camera, the direction of image recording can be changed by rotating the digital camera about the socket axis. Similarly, a specific extension cable 50 having a headphone jack 11 'at one end and a socket 10' at the other end is used, and the socket 10 of the digital camera 1 is connected to the headphone jack 1Γ of the specific extension cable 5σ, and the socket 10 of the specific extension cable 50 is connected 'Plug in the headphone jack u of the portable information terminal, the digital camera 1 can be operated freely. Similarly, by using the provided bracket 31 on the digital camera 1, the specific extension cable 50 is inserted through the hole 40 provided on the original portable information terminal and the bracket 31 of the digital camera 1, and the socket 10 of the specific extension cable 50 is inserted. 'Plug in the headphone jack 1Γ, the digital camera 1 can be attached to a portable information terminal for easy carrying. The shape of the stent 31 is not particularly limited as long as its opening is large enough to allow the strap to pass through 'and such a stent can be placed in any suitable position. Similarly, in the above-mentioned embodiment, by providing the key 32 and the guide groove 33 connected to the plug 10 to freely move the key 32 along the central axis 10b of the plug 10, as shown in FIG. 11, The plug 10 can support a digital camera. Furthermore, a cover is provided to protect the lens window 2c and connect the lens cover to the button 32. The lens cover can be made separate to move the button 32 °. If the arrangement can keep the plug 10 in the camera body, the cover can also be placed on the lens window 2c on. It is also possible to provide a sensor to detect whether the digital camera 1 has been flipped to 41 1245551 06283pif2.doc / 012 to flip the recorded image on the digital camera or on a portable information terminal. Question-like 'portable information terminal can be constructed' position information can be attached to the recorded image data by receiving such information from the base station, so that the position of the recorded image can be identified later. Next, the portable information terminal in the embodiment 1-2 will be explained. In the example shown in Embodiment 1-1, the plug 10 of the digital camera 1 is connected to the headphone socket 11. However, in this embodiment, the headphone socket 11 is a connector connected to a USB (Universal Serial Bus) cable. High-speed data transmission to personal computers, etc. Figure 12 shows the USB cable 100 used in this embodiment. As shown in the figure, the connector 101 of the USB cable 100 has a shape that can be connected to the headphone jack 11. The connector 101 has four contact points, which are arranged from the top as: a first data transmission / reception contact point 174, a second data transmission / reception contact point 173 ', a ground contact point 172, and a power contact point pi. The USB pen cable 100 is electrically connected and mechanically fixed to the portable type by inserting the connector into the headphone socket u on the right side surface 13c (refer to Figure 3) of the portable telephone 13 in a direction not shown in FIG. 3 Telephone 13. Similarly, by using the circular cross-sectional shape of the connection side 101 'the connector 101, the center line 101b of the connector 101 can be rotated 360 degrees as a rotation axis. Here, another connector located at the opposite end of the USB cable 100 is connected to an upstream device such as a personal computer, and various data exchanged between the external device and the portable information terminal may include audio data ^ video Data and text. Similarly, among the contact points of the connector 101, the ground contact point 172 42 1245551 06283piO.doc / 012 and the second data transmission / receiving contact point 173 may be left blank if the power is not supplied from an external device. Next, the internal circuit of the portable information terminal of this embodiment is shown in FIG. Similar to the embodiment 1-1, the portable telephone (including PHS) is regarded as a portable information terminal. As shown in this figure, the portable telephone 13 has a structure similar to that of the portable telephone 13 shown in FIG. 4, but the internal structure of the interface area 119 is different. In this embodiment, the connector 101 of the USB cable 100 is connected to the headphone socket 11, so that the interface must match the data transmitted from the USB cable 100 with the data processed by the portable telephone. For this reason, unlike the imaging interface 19b used in Embodiment 1-1, a USB interface 19c for converting data transmitted from the USB cable 100 and data processed by the portable telephone is provided on the interface area 119 . Moreover, when the USB cable 100 is connected to the headphone jack 11, the switching area 125 is connected to the output terminal of the headphone jack 11 to the USB interface 19c, and when the headphone microphone or stereo headphones are connected, the output of the headphone jack 11 is directed to the sound interface 19a. In this' switching area 125, once it is detected that the user has operated a certain function of the operating area 123, such as mode switching, the external device is identified (in this example, connected to the headphone socket 11 of the USB cable 100). Installation). By inputting a special signal output from an external device through the USB cable 100 and providing a further function to the switching area 125 to recognize a predetermined signal, it shows that the USB cable 100 is connected, and it is possible to automatically recognize the external device. In this example, the 'special signal' must be the signal specified by the portable telephone and external device 43 1245551 06283pif2.doc / 012. Next, the operation of the portable telephone 113 will be explained. First: ‘The portable phone 113 is in a normal enabled state. The user inserts the connector 101 into the earphone socket η of the portable phone n3 to obtain electrical and mechanical connection, and the current state is set to the USB mode. In this way, the signal that the response setting mode has been changed to the USB mode is transmitted to the CPU 126 of the portable telephone 113. The CPU 126 recognizes that the setting mode has been changed to the USB mode, and determines whether or not the jSB cable is connected to the headphone socket 11. If the result indicates that such a connection has been formed, the CPU 126 outputs a signal to the switching area 125 to notify that the USB mode has been set, and the switching area 125 then selects the USB interface 19c as the output interface of the headphone jack u. When real data transmission occurs, the data from the headphone jack η is input to the signal processing area 122 through the USB interface 19c, and the signal processing area 122 processes this input data ', and the processed data must be stored in the memory area 120. Of RAM. On the other hand, when the user issues an instruction to transfer data from the operation area 123 of the portable telephone 113, the signal processing area 122 reads special data from the RAM or ROM in the memory area 20, and the read data is to Output to the USB cable through the usb interface 19c and the headphone socket 11. In this way, the required data is transferred to the external device via the USB cable. Next, the portable information terminal in the embodiments 1-3 will be explained. The portable information terminal in this embodiment has the functions of the portable telephone 13 described in the embodiment hi and the portable telephone in described in the embodiment 1-2. That is, a ‘portable information terminal’ can be connected to a headset microphone, stereo headset, digital camera, and USB cable through the headphone jack η 44 1245551 06283pif2.doc / 012 as an external device. Therefore, the portable information terminal in this embodiment has a sound interface i9a, an imaging interface and a USB interface 19c in the interface area 219, as shown in FIG. 14, and these interfaces are connected to the outside of the earphone socket 11 according to FIG. Device type. Therefore, a more convenient portable information terminal can be provided. Next, the digital camera and the portable information terminal in the second embodiment will be explained. Here, portable telephones (including PHS) stand for portable information terminals. Fig. 15 shows a digital camera and a portable information terminal in the second embodiment. In this depiction, reference numeral 510 is associated with a portable telephone and reference numeral 520 is associated with a digital camera.

Similarly, the earphone socket 514 and plug 523 of the portable telephone have two contact points, a contact point 525a for transmitting clock signals; and a contact point 525b for transmitting data, but a contact point 525c for receiving data is also provided. Can receive data from external devices. Secondly, when the plug of the digital camera 520 is inserted into the socket of the portable information terminal 510 and the two devices are electrically connected, the portable information terminal 510 and the digital camera 520 are described with reference to FIGS. 17-21 action. First, referring to FIGS. 17 and 18, an example of two contact points between a portable telephone and a digital camera 520 will be described, that is, a portable telephone 47 1245551 06283pif2. doc / 012 510 has a contact point 527a for transmitting a clock signal; and a contact point 527b for receiving data, and the digital camera 520 has a contact point 525a for transmitting a clock signal; and a contact point 525b for transmitting data. In this example, there are two possibilities, one is to output the clock signal from the digital camera 520, and the other is to output the clock signal from the portable telephone 510. {Digital camera output clock signal} First, Figure Π shows that when the portable telephone 510 and the digital camera 520 are electrically connected and the clock signal is input from the digital camera 520 side to the portable telephone 510, the clock signal and related output Timing chart of the data. As shown in these figures, when the plug 523 of the digital camera 520 is inserted into the socket of the portable information terminal 510 and the two devices are electrically connected at time t0, the control area 520c inside the digital camera 520 is transmitted from The contact point 525a of the pulse signal outputs a clock signal (refer to FIG. 17A), and any data is output from the contact point 525b (refer to FIG. 17B) for transmitting data. According to this action, the clock signal is input to the control area 510g of the portable telephone 510 through the contact point 527 and the I / F interface 510a of the clock signal, and any data is received through the contact point 527b and I / F of the received data Interface 510a. In this example, any data refers to any random data, not special information pre-arranged between the digital camera and the portable phone. Therefore, once the clock signal and data are detected, the control area 510g decides that the external device connected at this time is the digital camera 520, and the control area 5 10g stores the image data output from the digital camera and the mobile phone 510 The contact points 525b, 527b, 481245551, 06283pif2 in the billion body area 510b used for data transmission. doc / 012 and input, and display the received image on the LCD display area 5 10f. Here, the image data stored in the memory area 510b in the portable telephone 510 can be freely displayed on the liquid crystal display area 51f, or the user performs some operations in the operation area 510e to delete it. {Handheld phone 510 output clock signal} Secondly, Fig. 18 shows the clock signal when the portable phone 510 is electrically connected to the digital camera 520 and the clock signal is input from the portable phone 510 side to the digital camera 520 side. Timing diagram with related output data. As shown in these figures, at time t0, the plug 523 of the digital camera 520 is inserted into the socket of the portable information terminal 510 and the two devices are electrically connected. The control area 52oc inside the digital camera 520 is transmitted through The contact point 527a of the clock signal transmitted by the portable telephone 510, the contact point 525a of the clock signal transmitted, and the I / F interface 520e of the digital camera receive the clock signal (refer to FIG. 18A). -Once the clock signal is received, the control area 520c in the digital camera 520 outputs data in a predetermined format from the data line area 525a. For example, if "AA55" is set to format data, the digital camera 520 outputs the signal shown in Fig. 21 to the portable telephone 510 through the contact 525a for transmitting the clock signal. In particular, the control area 520c outputs the predetermined data in the "AA55" format to the portable telephone 510 in synchronization with the input of the clock signal. Therefore, the data in the special format is input to the portable telephone 510 through the data line area 527b and the I / F interface 510a. In the above description, the established data is not limited to the above 8-bit data, but can include any type of data, as long as the mobile phone 510 and the number 49 1245551 06283pif2. The data between doc / 012 cameras 520 can be matched. If the data obtained in the control area 510g is the established data, it is determined that the external device connected at this time is the digital camera 52 and stores the data line area in the memory area 51ob in the portable g tongue machine 510. 525b, 527b and the image data output from the digital camera, and the received image is displayed on the liquid crystal display area 510f. Here, the image data stored in the memory area 5i0b of the portable telephone 510 can be freely displayed on the liquid crystal display area 51f, or the user performs some operations of the operation area 510e to delete. On the other hand, when data other than the predetermined format is input or no data is input ', it can be determined that the external device connected at this time is not the digital camera 52. The following example shows that the portable telephone 510 and the digital camera 520 are connected through three contacts. That is, the portable telephone 510 has a contact point 527a for transmitting a clock signal; a contact point 527b for receiving data and a contact point 527c for transmitting data; and the digital camera 520 has a contact point 525a for transmitting clock signals; a contact point for transmitting data 525b; and the contact point for receiving data 525c. In this example, there are two ways to supply the clock signal: the digital camera 520 outputs the clock signal or the portable phone 510 outputs the clock signal. {Digital camera output clock signal} First, Figure 19 shows the clock signal and related output data when the portable phone 510 and digital camera 520 are electrically connected and the clock signal is input from the digital camera side to the portable phone. Timing diagram. As shown in these figures, when at time t0, the portable information terminal 510 50 1245551 06283piO. The socket 514 of doc / 012 is connected to the plug 523 of the digital camera 520 and the two devices are electrically connected. The contact point 520c for transmitting the clock signal inside the digital camera 520 outputs the clock from the contact point 525a for transmitting the clock signal. Signal (refer to Figure 19A), and any data is output from the contact point 525b (refer to Figure 19B) of the transmitted data. According to this action, the clock signal is input into the control area 51 g of the portable telephone 510 through the contact point 527a and the I / F interface 510a transmitting the clock signal, and any data is received through the contact points 527b and I of the data. / F interface 510a. In this example, any data refers to any random data, not special information pre-arranged between the digital camera and the portable phone. Then, when the clock signal and data are detected in the control area 510g, it can be determined that the external device connected at this time is the digital camera 520, and the circuit in the I / F interface 510a is selected to conform to the image signal, and the circuit is switched . When the imaging circuit is selected, the operation keys and the like provided on the operation area 510e of the portable telephone 510 are regarded as the predetermined function keys of the digital camera 520. Then, when the user operates the operation area 510e as a button of a digital camera, the control area 510g transmits the relevant operation signal to the digital camera 520 through the contact point 527c for transmitting data. Then, the control area 520c inside the digital camera 520 can perform various actions related to the operation data to perform the actions specified by the portable phone 510 of the digital camera 520. {Handheld phone 510 output clock signal} Second, Figure 20 shows the clock when the portable phone 510 is electrically connected to the digital camera 520 and the clock signal is input from the 5-10 side of the portable phone to the digital camera 520 side. Timing diagram of signals and related output data. 51 1245551 06283pif 2. doc / 012 As shown in these figures, at time to, the plug 523 of the digital camera 520 is connected to the socket of the portable information terminal 51 and the two devices are electrically connected. In the control area inside the digital camera 520 520c receives the clock signal through the contact point 527a for transmitting the clock signal of the portable telephone 510, the contact point 525a for transmitting the clock signal of the digital camera, and the I / F interface 520e to receive the clock signal (refer to FIG. 20A). Upon receiving the clock signal, the control area 520c in the digital camera 520 outputs data in a predetermined format from the data line area 525a (refer to FIG. 20B). For example, if "AA55" is set as formatted data, the digital camera 520 outputs the signal shown in Fig. 21 to the portable telephone 510 through the contact point 525a of the transmitted clock signal. Therefore, the data in the special format is input to the portable telephone 510 through the data line area 527b and the I / F interface 510a. Then, when the control area 510g determines the data, and if the data matches the predetermined data, it determines that the external device connected at this time is the digital camera 520, and selects the circuit in the I / F interface 510a to conform to the image signal And switch the circuit. When the imaging circuit is selected, the operation keys and the like provided on the operation area 510e of the portable telephone 510 are regarded as the predetermined function keys of the digital camera 520. Then, when the user operates the operation area 510e as a button of a digital camera, the control area 510g transmits the relevant operation signal to the digital camera 520 through the contact point 527c for transmitting data (refer to FIG. 20C). Next, the control area 520c inside the digital camera 520 can perform various actions related to operation data to perform the actions specified by the portable telephone 510 of the digital camera 520. 52 1245551 06283pif 2. doc / 012 On the other hand, when data other than the predetermined format is input or no data is input, it can be determined that the external device connected at this time is not the digital camera 520. Next, in the third embodiment, a portable information terminal and a digital camera connected to the portable information terminal will be explained. This embodiment regards a portable telephone (including PHS) as a portable information terminal. Table 22 shows the architecture of a portable information terminal and a digital camera connected to the portable information terminal. In this figure, the portable telephone 630 stores or displays necessary image data received from the digital camera 650 through a special signal line. On the other hand, the digital camera 650 is operated by a power source supplied by the portable telephone 630, and transmits image data to the portable telephone 630 through a special signal cable. The portable telephone 630 and the digital camera 650 are connected by a signal line Lla ~ Llc, which are: transmitting power from the portable telephone 630 to the power line Lla of the digital camera 650; transmitting a signal for transmitting image data from the portable telephone 630 to the digital Data cable Lib for camera 650; and output (transmission) transmission from portable phone 630-ready signal and image data to data output signal cable Lie for digital camera 65. Here, the signal lines Lla ~ Lie are connected to a headphone jack η of the portable telephone 630. Next, the structure of the portable telephone 630 will be explained. The phone control area 602 has the following functions: (1) (terminal detection area), which detects the transmission-ready signal to show that image data can be transmitted from the digital camera 650 through the data output line Lie; 2 (terminal Side output area) to output the transmission-request signal to the digital camera 650 through the data demand signal line Lib, and the third (receiving area) to the data output signal line Lie 53 1245551 06283pif2. doc / 012 to receive image data transmitted from digital camera 650. Similarly, the telephone control area 602 controls the on / off of the power input to the digital camera 650 through the power line Lla. Furthermore, the telephone control area 602 controls each area of the portable telephone 630. The telephone control area 602 includes, for example, a CPU, and realizes functions stored in a memory area including ROM in advance by executing various programs to present its functions. The memory area 604 stores information related to various functions of the portable telephone 630, and stores image data received from the digital camera 650 according to the phone number of the phonebook function or controlled by the telephone control area 602. The display area 606 displays the operation status of various functions of the portable telephone 630, and displays information required for viewing, such as the telephone number of the transmitter and the reception situation during reception, the remaining battery power and the image data received from the digital camera 650. The power supply area 608 outputs power to each area of the digital camera 650, and its power on / off function is controlled by the action of the telephone control area 602. When using a phone or receiving image data from the digital camera 650, the operation area 610 is used to perform various functions, and has alphanumeric keys to enter numbers and letters, and form keys (not shown) to select various functions. Similarly, the wireless zone 670 is used to provide the phone functions of the portable telephone 630, and includes: a wireless zone 670a for processing wireless signals; a speaker 670b and a microphone 670c. The architecture of the wireless zone 670 is the same as that of a conventional portable telephone, and its detailed explanation is omitted. Next, the structure of the digital camera 650 will be explained. The camera control area 622 has the function of sending the ready signal forward for display 54 1245551 06283pif2. doc / 012 The image data is ready to be transmitted to the mobile phone 630 through the data output signal cable Lie (camera-side output area); the transmission request signal is detected through the data request signal cable Lib to request the image data to be transmitted to the mobile phone. Function of the mobile phone 630 (detection area on the camera side); Function of transmitting image data through the data output signal line Lie to the function of the portable phone 630 (transmission area). Similarly, the control area 622 controls each area of the portable telephone 630. The camera control area 622 includes, for example, a CPU, and executes its functions by executing various programs stored in ROM or the like in advance to realize the functions of the camera control area 622. The memory 624 stores image data continuously recorded by the digital camera 650, And the image data is continuously stored as a pattern, for example. Similarly, the imaging area 626 includes the imaging function of the digital camera 650, and has a lens and a contact point D (not shown), etc., and records the image of the recorded object under the control of the camera control area 622. The images recorded in the imaging area 626 are processed by the camera control area 622 and stored in the memory 624 as image data. Similarly, the digital camera 650 can automatically record images at a given interval under the control of the camera control area 622, store the image data in the memory 624, and update the image data at a given interval. Next, the process of transmitting image data from the digital camera 650 to the portable telephone 630 will be explained. Figure 23 shows the timing of transmitting image data from the digital camera 650 to the portable telephone 630. The image data S1 includes main image data equivalent to a pattern of a digital camera, a header and an end mark. In this figure, when the specific power supply voltage P [V] is (at time to) output from the portable telephone 630 to the digital camera 650 through the power line Lla, the digital 55 1245551 06283pif2. doc / 012 The camera 650 starts its operation, and the camera control area 622 changes the state of the data output signal line Lie from a high impedance (Hiz) state to a high potential (High) state. In this way, the digital camera 650 notifies the portable telephone 630 that it is ready to transmit image data. Similarly, the camera control area 622 starts each area of the digital camera 65, and then processes the first pattern (including the action of writing image data into the memory 624) recorded in the imaging area 626 (period M0). In the period M0, the data output signal line Lie is maintained in a high potential (High) state. When the above action is completed, the camera control area 622 changes the state of the data output signal line Lie to a low potential (Low) state, and L represents a transmission-ready signal (time t1). In this way, the mobile phone 630 notified that the preparation of image data transmission has been completed. The telephone control area 602 detects the low state of the data output signal line Lie, and continuously outputs special signals to the digital camera 650 through the data demand signal line Lib (time t2). Such a signal may be a clock signal (transmission request signal) C1 related to the number of bits of the image data S1. When the clock signal C1 is not output, the data demand signal line Lib is set to the low state by the telephone control area 602. In response to the clock signal C1, the camera control area 622 continuously reads the image data si stored in the memory 6 and 4 and outputs it to the data output signal line Lie. When the image data si related to a pattern is output, the camera control area 622 returns the data output signal line Lie to a high potential state (time t3), and notifies the portable telephone 630 that it is in the image data transmission ready state. At the same time, the camera control area 622 performs the image processing of the second pattern recorded in the imaging area (including writing the image data of a pattern to the memory 56 1245551 06283pi0-doc / 012 body 624) (time M1). When the above action is completed, the camera control area 622 changes the data output signal line Lie to a low potential state (time t4). In this way, the mobile phone 630 notified that the preparation of image data transmission was completed. After that, the operations from t1 to t4 are repeated, and the image data is transmitted when necessary. Therefore, the camera control area 622 transmits the image data in the pattern end, and the image data is transmitted in response to the phone control area 602 after the transmission ready signal (the low potential state of the data output signal line Lie) is transmitted. Clock signal. The phone control area 602 continuously receives the image data output to the data output signal line Lie, and writes this data to the memory 624, and when the image data related to a pattern is written to the memory 624, the image data is displayed in View on display area 606. Similarly, if the digital camera 650 stops transmitting image data, the phone control area 602 stops outputting a specific power supply voltage P [V] to the digital camera 650 (time tx) to stop the operation of the digital camera 650 without receiving more image data. In this way, the portable phone 630 does not supply power to the digital camera, so that it can avoid wasting the battery of the portable phone 630. On the other hand, if the portable telephone 630, for example, receives a mail while receiving image data, the telephone control area 602 preferentially receives the mail, so that the transmission of the clock signal C2 is temporarily suspended (AMa, AMb) and the clock signal C2 The system is divided into clock signals C2a to C2c and output. In response to the suspension of the clock signal C2, the camera control area 622 interrupts the output of the image data S2 (ΔMa, AMb). Moreover, the output of the clock signal C2 is restarted, and the clock signal (C2b and 57 1245551 06283pif2) after the clock signal (C2a) transmitted before the previous interruption. doc / 012 C2c) 'and in response to this, the camera control area 622 continuously outputs image data S2 (S2b, S2c), which subsequently follows the image data (S2a) transmitted before the previous interruption. According to this process, even when the telephone control area 602 temporarily interrupts the output of the clock signal C2 to perform other actions acquired by the non-digital camera, the interrupted image data S2 can be continuously received by re-outputting the clock signal C2. Similarly, when the camera control area 622 uses the latest digital camera to update (rewrite) the image data in the memory 624 at a given interval, if the interruption period (AMa, AMb) becomes longer than the update period of the image data, then During this period, the image data in the memory 624 is updated by the latest digital camera. In this example, the problem is that the image data output by the camera control area 622 according to the re-output of the clock signal C2 transmitted from the telephone control area 602 is different from the image before the clock signal was interrupted. Therefore, in this example, the camera control area 622 changes the data output signal line Lie to a high-potential state, and notifies the portable telephone 630 that it is in the image data transmission ready state. At the same time, the phone control area 602 detects the transmission ready signal, and interrupts the operation of restarting the reception of the interrupted image data S2 (restarting the clock signal C2 output). Then, when it detects the signal indicating the transmission permission state (low potential state of the data output signal line Lie), the phone control area 602 is between time t1 and t4, allowing normal image data receiving operations. With this action, when the interruption of the clock signal from the digital camera 650 is longer than the image update period of the digital camera 650, it is possible to restart the reception of the image data without any difficulty. The structure of the digital camera (frame) will be explained with reference to FIG. 24. In this figure, the image data S1 includes one equivalent to one recorded by the digital camera 650 58 1245551 〇6283pif2. The main image data 400b of doc / 012 patterns, the header 400a including the attributes of one pattern, and the end indication 400c showing the end of the image data S1. The relationship between the clock signal output and the image data output clock will be explained with reference to FIG. In this figure, each piece of metadata constituting the image data S1, that is, S1 [0], Sl [l], ... si [n], where η is an integer, and responds to the rising instant t2 [0 of the clock signal C1 ] (t2 [0] = t2), t2 [l], and output. Similarly, the period M2 is a period between the rising instant t2 [n] of the clock signal Cl and each metadata Sl [n] of the image data S1, and the period M3 is the width of the clock signal C1 in a high potential state And the period M4 (M5) is the time (frequency) of one cycle of the clock signal Cl. Similarly, the clock signal C1 is output during a fixed period, but its period can sometimes be changed between M4 ~ M5, depending on the processing status of the telephone control area 602. In this example, the output timing of the bit data Sl [n] of the video data S1 also changes accordingly (Sl [l] ~ Sl [2]). Here, the structure of the header 400a is shown in FIG. 26. For example, the header 400a includes 32 bytes to indicate certain items: [excess] to detect abnormalities in the received data, it will More details later; [Image data start notification]; Properties of main image data, such as [Image width] and [Image height]. Here, as long as the clock signal output from the telephone control area 602 is not interrupted, the camera control area 622 transmits each item data of the head 400a as all the image data S1 (Fig. 24). In this way, the exchange action (exchange instructions to confirm that the transmitter and receiver are in the state of starting the transmission / reception action), which was necessary for each item of the header in the past, can be a 59 1245551 06283pif2. The doc / 012 step is performed so that the time required to exchange actions can be shortened. Similarly, the telephone control area 602 can detect abnormalities in the received image data by checking the items in the header 400a in the image data S1, such as the [excessive] data and the [image data start notification with predetermined data] ] Information. For example, if the [redundant] data of the received image data is 552A "(hexadecimal), it is different from the fixed 値" AA55 "(hexadecimal), so its detection is abnormal. Figure 27 Display the data of the 2-byte end mark 400c ~ Example. In this figure, the end mark shows the data with "FFD9" (hexadecimal), and the end of the image data S1 is displayed. Fig. 28 shows in An example of the output sequence of the image data S1. In this figure, the end mark 400c is followed, and the main image data 400b is __Jia Transmission 'and the end mark 400c is the last transmission. Here, the digital camera 650 in this embodiment It can be directly placed on the portable telephone 630 to connect the two terminals. In this example, no connection cable is needed, but it is convenient to use. Similarly, the above embodiment represents the use of a clock signal to require the video data to be downloaded from the portable The information terminal is transmitted to the digital camera, but the data transmission technology is not limited to this example. For example, after notifying the portable information terminal that it is ready to transmit image data from the digital camera, the image data can be Transmit from the digital camera at the appropriate time. In this way, the data request signal line between the portable information terminal and the digital camera becomes unnecessary to facilitate its interconnection, and it can be reduced by reducing the signal line of the connector and the cable. Manufacturing cost. Similarly, the contents of the header and the end of the image data (box) can be calculated according to the number 60 1245551 06283piO. The type, function, and portability of doc / 012 cameras and portable information terminals are appropriately changed. Next, the portable information terminal in the fourth embodiment will be explained. Here, portable telephones (including PHS) are examples of portable information terminals. Fig. 29 shows the circuit architecture of the portable information terminal in this embodiment. In this example, the portable telephone 700 includes an antenna (not shown); an RF processing area 701, which processes sound signals and similar signals of the response terminal through the base station; a signal processing area 702; an operation area 704, which has ten Various keys in the keypad area; display area 706, which displays various data; ROM708, which stores various programs and fixed data; RAM716; external memory interface area 710; CPU712, which controls various areas; and portable terminal interface area 714.
