Description

The present invention relates to a communication connection technique for electronic devices capable of wireless communication.

Conventionally, there are electronic devices that connect to an external access point and electronic devices that connect without going through an external access point. Further, there is also an electronic device having a function of making a connection without going through an external access point when the connection of the external access point fails (for example, Patent Document 1).

JP-A-2017-175468

However, in the above-mentioned prior art, even if the connection of the external access point fails, it cannot be taken into consideration that it may be better not to make the connection without the external access point. When connecting to an external access point, the address of the device to be connected is determined by the external access point, and when connecting via the external access point, the address of the device to be connected is determined by a device other than the external access point. Therefore, the address determined by the external access point cannot be matched with the address determined by the device other than the external access point. Therefore, if the address is specified from the connection that does not go through the external access point, the external access point will be connected. You may not be able to connect because the address will not be recognized by the connection you make.

The present invention has been made in view of such a problem, and when the IP address of the connection destination is specified, it is specified regardless of whether the connection is connected to an external access point or not via an external access point. It is intended to provide a technology that enables connection by an IP address.

In order to solve this problem, for example, the electronic device of the present invention has the following configuration. That is,
Communication means that can operate as an access point and
A holding means for holding information related to a device that has connection experience,
A receiving means for accepting the selection of the device to be connected from the user,
When the IP address of the device to be connected is held by the holding means, the communication means is controlled to operate as an access point.
When the IP address of the device to be connected is not held by the holding means, it has a control means for controlling the user to be notified of the scan result of the surrounding external access point.

According to the present invention, when the IP address of the connection destination is specified, it is possible to connect with the specified IP address regardless of whether the connection is connected to an external access point or not via an external access point. ..

Then, the lens 103 is focused by shifting the position of the lens 103.

The image pickup unit 22 is an image pickup device composed of a CCD, a CMOS element, or the like that converts an imaged optical image into an electric signal. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal.

The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 23 or the data from the memory control unit 15. Further, in the image processing unit 24, a predetermined calculation process is performed using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result.

The output data from the A / D converter 23 is written to the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23, and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, moving images for a predetermined time, and audio.

Further, the memory 32 also serves as a memory (video memory) for displaying an image. The D / A converter 19 converts the image display data stored in the memory 32 into an analog signal and supplies it to the display unit 28. In this way, the display image data written in the memory 32 is displayed by the display unit 28 via the D / A converter 19. The display unit 28 displays on a display such as an LCD according to the analog signal from the D / A converter 19. The digital signal once A / D converted by the A / D converter 23 and stored in the memory 32 is analog-converted by the D / A converter 19 and sequentially transferred to the display unit 28 for display as an electronic viewfinder. It functions and can display through images (live view display).

The non-volatile memory 56 is a memory that can be electrically erased and recorded, and for example, EEPROM or the like is used. The non-volatile memory 56 stores constants, programs, and the like for the operation of the system control unit 50. The program referred to here is a program for the system control unit 50 to perform processing according to various flowcharts described later.

The system control unit 50 controls the entire digital camera 100. By executing the program recorded in the non-volatile memory 56 described above, each process of the present embodiment described later is realized. The system memory 52 is composed of RAM. In the system memory 52, constants and variables for the operation of the system control unit 50, a program read from the non-volatile memory 56, and the like are expanded. The system control unit also controls the display by controlling the memory 32, the D / A converter 19, the display unit 28, and the like.

The system timer 53 is a time measuring unit that measures the time used for various controls and the time of the built-in clock.

The communication unit 54 can communicate with an external device, can transmit an image to the external device by wireless connection or wired connection by wireless LAN, and can control the digital camera from the external device. In addition to functioning as a wireless LAN, the communication unit 54 can also operate as an access point.

The user can give various operation instructions to the system control unit 50 via the mode changeover switch 60, the first shutter switch 62, the second shutter switch 64, the operation unit 70, and the like.

The mode changeover switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image shooting mode, and the like. The modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, an aperture priority mode (Av mode), and a shutter speed priority mode (Tv mode). In addition, there are various scene modes, program AE modes, custom modes, etc. that are shooting settings for each shooting scene. The mode changeover switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image shooting mode, a playback mode, and the like. The modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, an aperture priority mode (Av mode), and a shutter speed priority mode (Tv mode). In addition, there are various scene modes, program AE modes, custom modes, etc. that are shooting settings for each shooting scene. The mode changeover switch 60 directly switches to any of these modes. Alternatively, after switching to the shooting mode list screen once with the mode changeover switch 60, one of the displayed plurality of modes may be selected and switched using another operating member. Similarly, the moving image shooting mode may include a plurality of modes.

The first shutter switch 62 is turned on by a so-called half-press (shooting preparation instruction) during the operation of the shutter button 61 provided on the digital camera 100, and the first shutter switch signal SW1 is generated. When the first shutter switch signal SW1 is turned on, the system control unit 5 performs AF (autofocus) processing, AE (autoexposure) processing, AWB (auto white balance) processing, EF (flash pre-flash) processing, and the like. Start operation.

The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, so-called full pressing (shooting instruction), and the second shutter switch signal SW2 is generated. When the second shutter switch signal SW2 is turned on, the system control unit 50 starts a series of shooting processes from reading the signal from the imaging unit 22 to writing the image data to the recording medium 200.

Each operation member of the operation unit 70 is assigned a function as appropriate for each scene by selecting and operating various function icons displayed on the display unit 28, and acts as various function buttons. The function buttons include, for example, an end button, a back button, an image feed button, a jump button, a narrowing down button, an attribute change button, and the like. For example, when the MENU button is pressed, various settable menu screens are displayed on the display unit 28. The user can intuitively make various settings by using the menu screen displayed on the display unit 28 and the up / down / left / right four-direction buttons and the SET button.

The operation unit 70 is various operation members as an input unit that receives an operation from the user. The operation unit 70 includes at least a shutter button 61, an electronic dial 71, a power switch 72, an up / down / left / right button 74, a SET button 75, a recording button 76, and a playback button 79.

The power supply control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power supply control unit 80 controls the DC-DC converter based on the detection result and the instruction of the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period.

The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F 18 is an interface with a recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and is composed of a semiconductor memory, a magnetic disk, or the like.

The configuration and basic operation of the digital camera 100 to which the embodiment applies have been described above. The digital camera 100 of the embodiment transmits the image file (stored in the recording medium 200) obtained by imaging to an external storage device (referred to as an FTP server) by wireless communication via the communication unit 54. , Can be saved. Therefore, in the following, the process of designating and connecting to the external storage device by designating the address will be described with reference to FIGS. 3 to 5. The non-volatile memory 56 stores and holds the IP address of an external storage device that has been connected in the past and communication parameters (SSID, encryption method, encryption key, etc.) with the AP (access point). It is assumed that it has been done.

3A to 3F are display examples of the display unit 28 when starting a communication connection when performing FTP transfer of the digital camera 100. This screen is displayed on the display unit 28 by the system control unit 50 in response to the user inputting an instruction to make a communication connection from the operation unit 70.

FIG. 3A is a display example in which the address is not set in the connection for which the address is specified. By selecting with the focus 301, a new connection to the external device is started with the address not set. The device to be connected (hereinafter, simply the connection destination) is, for example, an FTP server. Some FTP servers are stationary and the network to be connected is fixed and the address does not change, while others are portable PCs and smartphones so that the network to be connected changes and the address also changes. Even if the destination device is the same in FTP transfer, if the destination address changes depending on the network, it is necessary to set the changed address again as the connection destination. On the contrary, even if the destination devices for FTP transfer are connected by different networks, if the IP addresses of the destination devices are the same, the transfer can be performed without resetting the destination address.

FIG. 3B is a display example in which an address is specified, the address has already been set, and the address is set in the IPv4 format. By selecting the focus 302, the connection at the address set in the IPv4 format is started. It should be noted that the displayed address has a connection experience in the past and is stored in the non-volatile memory 56.

FIG. 3C is a display example in which an address is specified, the address has already been set, and the domain name has been set. By selecting the focus 303, the connection with the address set by the domain name is started. Obtain an address from the DNS server, specify the obtained address, and connect. You cannot connect to the DNS server because you cannot get the address on the network. It should be noted that the displayed address has a connection experience in the past and is stored in the non-volatile memory 56.

FIG. 3D is a display example in which the address is specified, the address has been set, and the address is set in the IPv6 format. By selecting the focus 304, the connection at the address set in the IPv6 format is started. It is not possible to connect to a network that does not support IPv6. It should be noted that the displayed address has a connection experience in the past and is stored in the non-volatile memory 56.

FIG. 3E shows a display example in which a connection destination is not set in a connection in which a connection other than an address is specified. By selecting the focus 305, the connection is started with the connection destination not set. The connection destination is, for example, a smartphone, and the UUID of the application used for the connection or the MAC address of the smartphone is used to specify the connection destination.

FIG. 3 (f) is a display example in which a connection destination is already set in a connection in which a connection other than the IP address is specified. By selecting the focus 306, the connection is started only for the selected smartphone. Since the UUID of the application used to specify the connection destination and the MAC address of the smartphone are not affected by the network, it is possible to connect to a network different from the previously connected network. The connection destination name has been connected in the past and is stored in the non-volatile memory 56.

FIG. 4 is a display example relating to the connected network.

FIG. 4A is a display example when the network is scanned and an attempt is made to connect to a network that has been connected. The system control unit 50 acquires the name of the external access point connected in the past from the non-volatile memory 56 and displays the SSID 401.

If the network is not the one you want to connect to, the user may operate the operation unit 70 and select network change 402. The system control unit 50 that detects this selection cancels the connection shown in the figure, scans the network, and then displays a list of access point names as scan results. Examples that require network changes include trying to connect to a network that is not connected to the Internet, or trying to connect to a network that is not connected to the device you want to connect to.

FIG. 4B is a display example when the digital camera 100 of the embodiment serves as an access point to generate a network. This is one of the connections without going through an external access point. The system control unit 50 displays the access point SSID 403 and password 404 on the display unit 28. If the network is not the one the user wants to use, selecting network change 405 will stop the network, scan the network, and then display the scan results. As an example of creating a network by using a camera as an access point, the network is scanned at the start of connection, and if there is no network that has been connected, the camera automatically becomes an access point. In addition, after scanning the network, when displaying the scan result, the option to use the camera as an access point is displayed, and the user operates to select to use the camera as an access point.

FIG. 4C is an example of displaying the scan result after scanning the network. The option 406 for using the digital camera 100 as an access point and one of the detected external access points 407, 408, and 409 can be selected and displayed in a list. If the network using the digital camera 100 as an access point cannot connect to the connection destination, the option 406 using the digital camera 100 itself as an access point may be hidden or grayed out so that the display cannot be selected. As an example of not being able to connect to the connection destination in a network using the digital camera 100 as an access point, if the connection destination is specified as a domain name even though it cannot be connected to the DNS server, or if the connection destination is specified even though it does not support IPv6 format, the connection destination is specified. This is the case of IPv6 format.

FIG. 5 is a flowchart showing a network determination process used for connecting the system control unit 50 of the digital camera 100 in the embodiment. The program according to this flowchart is stored in the non-volatile memory 56, and the user instructed the connection via the operation unit 70 on any of the screens of FIGS. 3A to 3F. It is something to start with.

In S501, the system control unit 50 scans the network, holds the scan result, and proceeds to the process in S502.

In S502, the system control unit 50 determines whether or not there is an external access point that has been connected in the past in the scan result with reference to the non-volatile memory 56. Then, the system control unit 50 proceeds to S509 if there is an external access point that has been connected, and to S503 if it does not exist.

In S503, the system control unit 50 determines whether the connection this time is for the purpose of FTP transfer. As described above, since FIGS. 3A to 3F are connection GUIs in FTP transfer, this determination is Yes. In S503, No is a connection other than FTP transfer, but this is omitted because it is not directly related to the embodiment. Further, for example, the attribute information indicating whether or not the connection destination device having been connected in the past is an FTP server may be stored in the non-volatile memory 56 in association with the IP address. In the example of FIG. 3B, when the IP address "192.168.1.20" is the FTP server and the user specifies this IP address and inputs a connection instruction, the system control unit 50 sends the attribute information to S503. It can also be judged as Yes.

In S504, the system control unit 50 determines whether or not the connection destination is set by the address. The system control unit 50 proceeds to S505 when it is determined that the address is set, and to S506 when it is determined that the address is not set. The reason for proceeding to S506 is that the user wants to connect to an external access point and set the connection destination address. The IP address assigned by the external access point cannot be controlled by the digital camera 100, but in the connection using the digital camera 100 as the access point, the IP address assigned by the digital camera 100 can be controlled. Make sure the address is set.

In S505, the system control unit 50 determines whether the connection destination address is in the IPv4 format. The system control unit 50 proceeds to S510 if it determines that it is in the IPv4 format, and proceeds to S506 if it determines that it is not in the IPv4 format. In addition, as an example other than the IPv4 format, there are a domain name and an IPv6 format.

In S506, the system control unit 50 displays the scan result list held on the display unit 28, and proceeds to the process in S507. In S507, the system control unit 50 determines whether the user has selected the digital camera 100 itself as an access point to generate a network. When the user chooses to use the digital camera 100 as an access point to generate a network, the system control unit 50 proceeds to S510, and if not, proceeds to S508.

In S508, the system control unit 50 determines whether or not the user has selected to connect to the external access point. The system control unit 50 proceeds to S509 when it is determined that the connection to the external access point is selected, and proceeds to S507 when it is determined that the connection to the external access point is not selected.

In S509, the system control unit 50 connects to the external access point and proceeds to process in S517.

On the other hand, when the process proceeds to S510, the system control unit 50 activates the digital camera 100 as an access point to generate a network, and proceeds to the process to S511.

In this S511, the system control unit 50 determines whether or not the IP address of the digital camera 100 itself is explicitly set by the user in advance. If it is determined that the system control unit 50 is set, the process proceeds to S514, and if it is determined that the process is not set, the process proceeds to S512.

In S512, the system control unit 50 determines whether or not the current communication is intended for FTP transfer (this determination may be the same as in S503). The system control unit 50 proceeds to S515 when it is determined that the transfer is other than FTP transfer, and proceeds to S513 when it is determined to be FTP transfer.

In S513, the system control unit 50 determines whether or not the IP address of the connection destination has been set. The system control unit 50 proceeds to S516 if it determines that the IP address of the connection destination has been set, and proceeds to S515 if it determines that the IP address of the connection destination has not been set.

In S514, the system control unit 50 sets the IP address of the digital camera 100 with the IP address preset by the user, and proceeds to the process in S517.

In S515, the system control unit 50 sets the IP address of the digital camera 100 with a predetermined IP address, and proceeds to the process in S517.

In both S514 and S515, when the user specifies the connection destination by the IP address and the IP address set in the digital camera 100 and the connection destination IP address are not the same network, the system The control unit 50 may display an error message indicating that the connection cannot be made on the display unit 28.

In S516, the system control unit 50 sets the IP address of the digital camera 100 so that the network becomes the same as the connection destination address, and proceeds to the process in S517. Specifically, among the IP addresses, the network part is made the same and the host part is made variable. For example, when the connection destination IP address in FIG. 3B is "192.168.1.20" and the network address is "192.168.1.0", the value of the address of the network part is "192". .168.1 ". Therefore, in this case, the system control unit 50 sets, for example, "192.168.1.10" as the IP address of the digital camera 100 (the same network address may be different from the connection destination IP address). As a result, regardless of whether the IP address of the connection destination device is set by connecting to an external access point or when a digital camera is used as the access point, the connection is made using that IP address. You will be able to.

In S517, the system control unit 50 determines whether there is a request for network change by the user. The system control unit 50 proceeds to S519 when it is determined that there is a request for network change by the user, and proceeds to S518 when it is determined that there is no request for network change.

In S518, the system control unit 50 determines whether or not there is a connection of the communication destination. The system control unit 50 terminates this if there is a connection of the communication destination, and returns the process to S517 when it determines that there is no connection of the communication destination. When there is a communication destination connection, the system control unit 50 shifts to the FTP transfer process of the captured image file. In the FTP transfer process, the system control unit 50 simply transfers all the image files stored and held in the recording medium 200 to the connection destination (FTP server). Omit.

In S519, the system control unit 50 scans the network, holds the scan result, and proceeds to the process in S508.

As described above, according to the present embodiment, when the user specifies the connection destination by the address in the connection operation with the communication destination, the connection to the external access point has priority. Therefore, if the specified connection destination address is the network generated by the external access point, the connection can be made using it as it is. On the other hand, when the external access point cannot be detected (in the embodiment, when the access point having connection experience in the past cannot be detected), the network represented by the connection destination address is generated, and then the connection with the connection destination is performed. Therefore, it is possible to connect without changing the connection destination address.

Further, when a network is generated by using the communication unit 54, the IP address of the device to which the IP address is first connected by automatic acquisition may be controlled to be the same as the IP address of the connection destination specified by the user. good. This is especially the case where the digital camera and the device to be the FTP transfer destination exist in front of the user and one-to-one communication can be expected, and the DHCP server is made to function via the communication unit 54. It is effective for.

Further, according to the above embodiment, when there is no access point having connection experience among the scanned access points and the domain name is specified as the connection destination device specified by the user, the detected access point is used. Attempts to connect via the access point selected by the user. That is, since the communication unit 54 is not activated as an access point, the number of steps required to complete the connection can be reduced.

In the above embodiment, an example of application to a digital camera has been described. However, the present invention is not limited to the above embodiment because it can be applied to any electronic device (for example, a smart phone) having a function of creating or editing a file to be transferred, which is stored and managed in an external device. ..
