  In recent years, camera devices have been used in various fields with the spread of digital cameras having an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). For example, Patent Document 1 discloses an FA camera device applied to the industrial field. According to the FA camera device, in the electronic component mounting device, the substrate recognition is performed based on the acquired image data, and the positioning accuracy of the head that sucks the component is improved. In such a camera device, as functions are diversified, various functions and performances are required. If the requested function cannot be handled by a general-purpose camera device, a dedicated camera device that implements the function is required. However, a dedicated camera device specialized for a predetermined function takes a lot of time to manufacture, and there is a concern that the cost is higher than that of a general-purpose camera device.

  In addition, the usage and required performance of the camera device may be changed after installation. Then, since a lot of time is required for the correction accompanying this, there is a problem that correction cannot be made immediately and the correction cost is required. For example, Patent Document 2 discloses a camera configured by detachably connecting an imaging module provided with an imaging element to a camera body. Thereby, for example, even if the imaging range and resolution required for the camera device are changed, it is considered that a certain degree of change can be accommodated by replacing the imaging module.

Also, the printed circuit board CB is coated with solder at the mounting position of the electronic component by a cream solder printing machine, and is transported through a plurality of mounting devices in order to mount the electronic component. Thereafter, the printed circuit board CB on which electronic components are mounted is transported to a reflow furnace and soldered to form an integrated circuit.

  As shown in FIG. 1, the electronic component mounting apparatus 1 includes a control device 2 and a camera device 10. The control device 2 includes a CPU and a memory, and inputs a command value for the electronic component mounting device 1 and information output from the camera device 10 and a sensor. And the control apparatus 2 controls each axis motor, each apparatus, etc. of the electronic component mounting apparatus 1 so that an electronic component is mounted | worn appropriately to the printed circuit board CB based on these command values and various information. In the present embodiment, the camera device 10 is used as a substrate camera that captures an image of the printed circuit board CB transported to a specified position by a transport device such as a conveyor when the electronic component mounting device 1 mounts the electronic component. Yes.

  More specifically, the camera device 10 that is a substrate camera images the printed circuit board CB that has been transported to a specified position and clamped based on an imaging command that is input through communication with the control device 2. Then, the camera device 10 performs predetermined image processing on the acquired image data and outputs it to the control device 2. Next, the control device 2 recognizes the board marks provided at the two opposite corners of the printed circuit board CB as the reference position from the image data. As a result, the control device 2 can mount the electronic component at the set coordinate value. In other words, by correcting the position error that occurs when the printed circuit board CB is clamped based on the image data, the accuracy of component mounting is improved. Thus, in the present embodiment, the control device 2 is an external device positioned above the camera device 10, and the printed circuit board CB is a subject imaged by the camera device 10.

  In addition, the camera device 10 can be used for a component camera that captures the state of an electronic component sucked by a suction nozzle of a component mounting head, for example. Furthermore, it can also be used in the electronic component mounting apparatus 1 as a compound eye type camera apparatus 10 having a plurality of image sensors for imaging a plurality of subjects. In any case, the operation of the camera device 10 is controlled by the control device 2 which is a host device. The camera device 10 can also be incorporated into a board inspection apparatus that inspects the printed circuit board CB on which electronic components are mounted. In this case, the camera device 10 is used as an inspection camera that images the printed circuit board CB. Thus, the camera apparatus 10 can be used for purposes other than board production. In this case, a general-purpose personal computer or a dedicated image processing board is used as the host device.

  The camera device 10 is configured by detachably connecting modules selected from three or more modules having different functions. In the present embodiment, as shown in FIG. 2, the camera apparatus 10 captures an image among modules including an imaging module 11, an image processing module 12, an external communication module 13, an autonomous operation module 14, and a light source module 15. The module 11, the image processing module 12, and the external communication module 13 are selected one by one and connected in this order.

  The illustrated modules 11 to 15 have different functions. Each module 11-15 is provided with a plurality of types having similar functions. Each of the modules 11 to 15 includes a communication unit that can communicate with each other using a common signal that is shared, and is housed in a casing having the same shape provided with a detachable connecting unit. And the camera apparatus 10 can be selected from each module 11-15 according to a use, and can be combined freely. It is also possible to connect a plurality of modules of the same type. Details of functions and configurations of the modules 11 to 15 will be described later.

  The imaging module 11 is a module that captures an image of a printed circuit board CB that is a subject and acquires image data. As shown in FIG. 3, the imaging module 11 includes a PLD 11a, a memory unit 11b, and an image sensor 11c.

The PLD 11a is an integrated circuit capable of defining a logic circuit corresponding to the above program even after the imaging module 11 configures the camera device 10. More specifically, this corresponds to an FPGA (Field Programmable Gate Array), CPLD (Complex Programmable Logic Device), or the like.

  And the program is mounted by the system construction device 20 so that the PLD 11a has a function necessary as the imaging module 11 of the camera device 10. The programs installed in the PLD 11a are a device driver that operates the image sensor 11c, a communication program that communicates with the image processing module 12 to be connected, and the like. The communication program can communicate with each other by a common signal shared between the modules 11 to 15. Therefore, the PLD 11a also functions as a communication unit in the imaging module 11.

  The memory unit 11 b is a flash memory that stores hardware information related to the configuration of the imaging module 11. Specifically, the hardware information includes the number of pixels of the image sensor 11c, the image transfer speed, and the like. The image sensor 11c is an image sensor such as a CCD or a CMOS. The image sensor 11c is arranged so that its imaging surface is perpendicular to the optical axis of a lens provided in the imaging module. Then, the image sensor 11c converts the signal into a digital signal by a signal charge generated according to the intensity of light imaged on the imaging surface by the lens, and images the subject. The PLD 11a converts the image data into image data based on the digital signal output from the image sensor 11c. In the present embodiment, the imaging module 11 has a monocular configuration having only one set of a lens and an image sensor 11c.

  The image processing module 12 is a module that executes image processing on the image data acquired by the imaging module 11. As shown in FIG. 3, the image processing module 12 includes a PLD 12a and a memory unit 12b. The PLD 12 a is a circuit element that can mount a program that executes an image processing function assigned to the image processing module 12. Since the PLD 12a of the image processing module 12 is the same as the PLD 11a of the imaging module 11, detailed description thereof is omitted.

  The programs mounted on the PLD 12 a of the image processing module 12 are an image processing program as a board camera, a communication program for communicating with the imaging module 11 and the external communication module 13 to be connected. This image processing program executes image processing so that the control device 2 that has input image data from the camera device 10 can recognize the substrate mark as a reference position. This image processing is, for example, binarization of image data, filtering, hue extraction, and the like, and is selectively implemented as necessary. In addition, the communication program performs communication using a common signal, similar to the one installed in the PLD 11a of the imaging module 11. Therefore, the PLD 12a also functions as a communication unit in the image processing module 12.

  The memory unit 12b is a non-volatile flash memory that can change the stored content by rewriting and retains the stored content even when the power is turned off. The memory unit 12b is used as an auxiliary storage unit, for example, temporarily holding image data during image processing by the PLD 12a.

  The external communication module 13 is a module that communicates with the control device 2 that is an external device. As shown in FIG. 3, the external communication module 13 includes a PLD 13a, a memory unit 13b, and an interface IC 13c. The PLD 13 a is a circuit element that can mount a program that executes an external communication function assigned to the external communication module 13. Since the PLD 13a of the external communication module 13 is the same as the PLD 11a of the imaging module 11, detailed description thereof is omitted.

  The programs installed in the PLD 13a of the external communication module 13 are a device driver that operates the interface IC 13c, a communication program that communicates with a connected image processing module, and the like. In addition, this communication program communicates with a common signal, similar to the one defined in the PLD 11a of the imaging module 11. Therefore, the PLD 13a also functions as a communication unit in the external communication module 13.

  The memory unit 13 b is a flash memory that stores hardware information related to the configuration of the external communication module 13. Specifically, the hardware information includes the transfer speed and transfer bus width of the interface IC 13c. The interface IC 13 c is an electronic circuit having a predetermined communication function that communicates with the control device 2. Such an interface IC 13c is designed according to various communication protocols and communication standards, and has a communication form corresponding to a data transmission path such as a parallel interface, a coaxial cable, or a USB.

  The autonomous operation module 14 is a module to which a function for automatically performing a predetermined operation in the camera device 10 based on image data acquired by the imaging module 11 is assigned. Examples of such functions include an automatic tracking function that changes the imaging direction of the camera device 10 in accordance with the movement of the subject, and an automatic imaging function that recognizes a specific mark of the subject and outputs an imaging command to the imaging module 11. The autonomous operation module 14 has a communication unit capable of communicating with other modules by a common signal regardless of the function. The communication unit of the autonomous operation module 14 may be configured to implement a communication program in a PLD or a microcomputer that executes an autonomous operation function.

  The light source module 15 is a module assigned with an illumination function for irradiating a subject when the camera device 10 performs imaging based on a control command of the control device 2 that is a host device. Such a light source module 15 may have a function of adjusting an irradiation amount according to a measurement value by an illuminance sensor using an LED or a light bulb as a light source. The light source module 15 includes a communication unit that can communicate with other modules by a common signal regardless of the configuration of the light source module 15. The communication unit of the light source module 15 may be a module that implements a communication program in a PLD or a microcomputer that performs an illumination function.

  The camera device 10 configured as described above, for example, captures an image of the printed circuit board CB based on an imaging command from the control device 2 and outputs image data that has undergone image processing to the control device 2. Thus, the camera device 10 is used as a board camera in the electronic component mounting apparatus 1. Here, when an imaging command is input to the camera device 10, the PLDs 11 a, 12 a, and 13 a of the modules 11 to 13 execute predetermined programs to execute imaging of an object, image processing, and output of image data. At this time, the PLDs 11a, 12a, and 13a of the modules 11 to 13 communicate with each other using a preset common signal. More specifically, the PLDs 11a, 12a, and 13a are connected in a bus format, for example, and perform synchronous or asynchronous serial communication at a predetermined transfer rate. With such a configuration, even when various modules are selectively connected to form a camera device, communication between the modules is possible.

  Further, when the power of the camera device 10 is turned on, the image processing module 12 inputs hardware information stored in the memory unit 11b of the imaging module 11 to be connected. As a result, the image processing module 12 inputs image data at a predetermined image transfer speed according to the hardware information related to the configuration of the imaging module 11, and executes image processing corresponding to a predetermined number of pixels. Similarly, the image processing module 12 inputs hardware information stored in the memory unit 13b of the connected external communication module 13. As a result, the image processing module 12 transfers the image data subjected to the image processing to the external communication module 13 according to the hardware information related to the configuration of the external communication module 13.

(Configuration of system construction device 20)
Next, the configuration of the system construction device 20 will be described with reference to FIGS. The system construction device 20 implements a function according to the application of the camera device 10 and includes dedicated software for the camera device 10 composed of a plurality of modules. As illustrated in FIG. 3, the system construction device 20 includes a communication unit 21, a program mounting unit 22, an information acquisition unit 23, a display unit 24, a simulation unit 25, and a determination unit 26.

  The communication unit 21 is communicably connected to the external communication module 13 configuring the camera device 10. In the present embodiment, the communication unit 21 is communicatively connected to the camera device 10 using a communication unit that communicates with the control device 2 that is an external device. That is, the camera device 10 and the communication unit 21 are connected by a data transmission path such as USB included in the selected external communication module 13.

  The program mounting unit 22 transfers the program displayed on the display unit 24 to the PLDs 11a, 12a, and 13a of the modules 11 to 13 via the communication unit 21. More specifically, the program mounting unit 22 defines a logic circuit corresponding to a program in the PLD 11 a that is an integrated circuit such as an FPGA for the imaging module 11. As a result, the PLD 11a can be driven to perform a predetermined function. Similarly, the program implementation unit 22 defines the logic circuit by transferring the program to the other PLDs 12a and 13a via the communication unit. In the present embodiment, each of the modules 11 to 13 has the PLDs 11a, 12a, and 13a. However, for example, some or all of the modules 11 to 13 may have a microcomputer instead of the PLD. . In such a case, the program mounting unit 22 stores the program in a non-volatile memory housed in the microcomputer so that the microcomputer exhibits a predetermined function.

  The information acquisition unit 23 acquires module information of each module 11 to 13 selected to configure the camera device 10. The module information acquired by the information acquiring unit 23 includes functions assigned to the modules 11 to 13 and hardware information related to the configuration of the modules 11 to 13. Therefore, the information acquisition unit 23 acquires hardware information stored in the memory units 11b, 12b, and 13b of the modules 11 to 13 via the communication unit 21.

  As shown in FIG. 4, the display unit 24 displays selectable programs that can be installed in the PLDs 11 a, 12 a, and 13 a based on the module information of the modules 11 to 13 acquired by the information acquisition unit 23. The display unit 24 includes a program display area Fp that displays programs that can be installed in the PLDs 11a, 12a, and 13a as icons, and a selection display area Fs that displays icons of the selected programs. The program display area Fp includes device drivers of modules constituting the camera apparatus 10 and various image processes that can be executed by the image processing module 12 as mountable programs.

  The device driver displayed in the program display area Fp is a device driver corresponding to the module based on the hardware information acquired by the information acquisition unit 23, and is a program for driving the hardware included in the module. More specifically, what kind of image sensor 11c is provided in the imaging module 11 is acquired as hardware information, and a device driver necessary for operating the image sensor 11c is displayed. In the program display area Fp, the program name of the device driver may be directly displayed, but in the present embodiment, a device (image sensor 11c, interface IC 13c) corresponding to the selectable device driver is displayed. Like to do.

  The image processing displayed in the program display area Fp is displayed when the plurality of modules constituting the camera device 10 includes the image processing module 12 that executes image processing on the image data. In the present embodiment, since the image processing module 12 is included, the display unit 24 displays image processing executable as a program in the program display area Fp. Such device drivers and image processing are displayed as icons symbolizing the respective functions or processing. Then, by dragging and dropping this icon from the program display area Fp to the selection display area Fs, the program mounting unit 22 considers that a device driver or image processing corresponding to the icon has been selected. Conversely, by dragging and dropping an icon from the selection display area Fs to the program display area Fp, or deleting the icon in the selection display area Fs, the program implementation unit 22 selects the device driver or image processing corresponding to the icon. It is considered that it was canceled.

  Here, when a plurality of image processes are selected, the selected image processes are displayed in the designated execution order in the selection display area Fs. Here, the image processing module 12 may execute a plurality of image processes on the image data in a predetermined order. This is because even when similar image processing is executed, the result differs depending on the execution order. For example, as shown in FIG. 5A, when binarization processing is executed after noise cancellation processing is performed on certain image data, image data as shown in the rightmost diagram is obtained. On the other hand, as shown in FIG. 5B, when the noise cancellation process is executed after the binarization process is performed on the same image data, the image data as shown in the rightmost figure is obtained. Thus, as shown in the rightmost diagrams of FIGS. 5A and 5B, since the results obtained by the image processing are different, the selected display region Fs executes a plurality of selected image processing. By displaying in order, the execution order is made visible.

  When one or more image processes are selected in the selected display area Fs, the simulation unit 25 assumes that the image processes have been executed in the designated execution order and simulates the image data after the execution. This is intended to determine whether the currently selected image processing and execution order are appropriate as functions required for the image processing module 12. The simulation unit 25 is for obtaining a result of virtual image processing, and the image data to be subjected to image processing may be one captured by the connected camera device 10 or previously. It may be a prepared sample.

  The determination unit 26 appropriately determines the program selected for the module based on the acquired module information. The display unit 24 displays selectable programs that can be installed in the PLDs 11a, 12a, and 13a of the modules 11 to 13, but before the logic circuit is defined in the PLDs 11a, 12a, and 13a, the program is determined by the determination unit 26. Confirm. That is, the determination unit 26 determines whether there is a program that is indispensable for the module, whether the program is selected, and whether a driver corresponding to the sensor or IC provided in the module is selected. It is.

(Implementation of program by system construction device 20)
The flow of system construction of the camera device 10 by the system construction device 20 will be described with reference to FIG. Here, a case where the camera apparatus 10 having the above configuration is targeted is illustrated. In other words, the camera device 10 is composed of modules 11 to 13 having three different functions, and each of the modules 11 to 13 has PLDs 11a, 12a, and 13a that can mount programs.

  First, as a preparation step (S10), the camera device 10 and the system construction device 20 are connected to prepare for communication (S101). Here, the external communication module 13 of the camera device 10 and the communication unit 21 of the system construction device 20 are connected. Then, the system construction device 20 communicates with the camera device 10 by communication means in which the external communication module 13 communicates with the control device 2. Next, the information acquisition part 23 acquires the module information of each module 11-13 via the communication part 21 (S102). Thereby, the number of modules constituting the camera device 10 and the function and hardware information for each module are input to the system construction device 20.

  As shown in FIG. 4, the display unit 24 displays a program that can be installed in each of the PLDs 11a, 12a, and 13a as an icon in the program display area Fp based on the acquired module information related to the camera device 10. The program displayed here includes module device drying and image processing as described above. Then, among these icons, the mounted one is dragged and dropped from the program display area Fp to the selection display area Fs to select a program (S20). Conversely, the program can be deselected by dragging and dropping the icon from the selection display area Fs to the program display area Fp, or by deleting the icon in the selection display area Fs.

  When the program selection is completed, a simulation is performed for the selected image processing (S30). When the processing confirmation button is pressed on the screen (see FIG. 4) by the display unit 24, the simulation unit 25 executes image processing on the sample image data prepared in advance in the designated execution order. Here, sample image data is used, but image data actually captured by the camera device 10 may be used. Then, based on the image data obtained as the simulation result, it is determined whether the currently selected image processing and execution order are appropriate (S40).

  If it is determined from the simulation result that the current selection is not appropriate (S40: No), the process returns to S20 to adjust the selection and execution order of image processing. Then, if necessary, the simulation may be performed again (S30). If it is determined that the currently selected image processing and execution order are valid by repeating these steps (S40: Yes), the programs selected for all the modules constituting the camera device 10 are valid. (S50). In this case, when the determination button is pressed on the screen by the display unit 24 (see FIG. 4), the determination unit 26 executes the determination process. And the determination part 26 determines whether the program corresponding to the icon currently displayed on the selection display area | region Fs is appropriate based on the acquired module information.

  If the currently selected program is not appropriate as a result of the determination (S50: No), an error (not shown) is displayed to prompt reselection of the program, and the process returns to S20 to select a device driver or image processing. On the other hand, if the currently selected program is appropriate (S50: Yes), the program mounting unit 22 mounts the program via the communication unit 21 (S60). That is, the program mounting unit 22 transfers the program corresponding to the icon displayed in the selection display area Fs of the display unit 24 to the PLDs 11a, 12a, and 13a of the modules 11 to 13 via the communication unit 21. As a result, the PLDs 11a, 12a, and 13a can be driven so that a logic circuit corresponding to a program is defined and a predetermined function is exhibited. In this way, the implementation of the program by the system construction device 20 is completed, and the system as the camera device 10 is constructed.

(Effects of the system construction device 20)
The system construction device 20 described above performs system construction for the camera device 10 configured by connecting a plurality of modules having different functions. Since this camera apparatus 10 can connect a plurality of modules as required, it can be easily applied to various applications. The system construction device 20 is configured to transfer a program that the program mounting unit 22 mounts on the PLDs 11a, 12a, and 13a of the modules 11 to 13. Thereby, the camera apparatus 10 can construct | assemble a system so that the function each allocated to each module with the mounted program may be exhibited. Therefore, a camera device having a higher degree of design freedom than conventional ones and capable of supporting required functions and performances can be configured. The plurality of modules 11 to 15 can be designed and inspected in module units, and existing modules can be used. Thereby, compared with the case where a dedicated camera apparatus is manufactured, a development man-hour can be reduced significantly.

  Further, the display unit 24 displays a program that can be installed in the PLDs 11a, 12a, and 13a based on the module information in a selectable manner. Here, since the camera device 10 is configured by selecting a plurality of modules according to the usage or the like, the hardware configuration is not specified until the combination is determined. Therefore, first, when a combination of predetermined modules constituting the camera apparatus 10 is determined, module information such as what functions each module has is acquired by the information acquisition unit 23. About the acquisition method of module information, you may acquire by communicating with the camera apparatus 10 connected with the system construction apparatus 20, and you may acquire it by inputting the combination of the module determined by the user. And the display part 24 displays a program based on this module information, and the selection of a program is assisted and becomes easy. Therefore, the system construction of the camera device 10 can be simplified.

  Furthermore, programs that can be installed in the PLDs 11a, 12a, and 13a provided in the modules 11 to 13 are displayed on the display unit 24 as icons. A program can be easily selected by dragging and dropping this icon from the program display area Fp to the selection display area Fs. In such a configuration, the selection of the program can be canceled by dragging and dropping from the selection display area Fs to the program display area Fp. As described above, by assigning a function for selecting or canceling a program to a simple mouse gesture such as drag and drop, it is possible to simplify the implementation of the program in each of the modules 11 to 13 of the camera device 10.

  The display unit 24 displays a device driver corresponding to the module as a program in the program display area Fp based on the hardware information. Some of the modules 11 to 13 constituting the camera apparatus 10 execute assigned functions by driving hardware included in the modules. For this reason, the display unit 24 displays a device driver corresponding to the module, thereby assisting selection of the device driver. As a result, the system construction device 20 can simplify the selection of a program as necessary.

  The display unit 24 displays image processing executable by the image processing module 12 in the program display area Fp. The camera device 10 may be configured to include an image processing module 12. Therefore, by displaying image processing executable by the image processing module 12 in the program display area Fp, selection of image processing can be simplified. In the selection display area Fs, a plurality of selected image processes are displayed in the order of execution. As a result, the execution order of the image processing can be visually confirmed, so that it is possible to prevent the image processing order from being erroneously designated.

  In addition, the system construction device 20 can simulate the image processing selected by the simulation unit 25 as executed in the designated execution order. This makes it possible to determine whether the currently selected image processing is appropriate as the image processing required for the image processing module 12. Thereby, since suitable image processing can be selected easily, the man-hour required for the system construction of the camera apparatus 10 can be reduced. Furthermore, the appropriateness of the program selected by the determination unit 26 is determined. Thereby, it is possible to determine appropriateness before the selected program is installed. This can reliably prevent selection of an incorrect program.

  Furthermore, the communication unit 21 is assumed to be communicably connected to the camera device 10 by a communication unit that allows the external communication module 13 to communicate with an external device. Here, the external communication module 13 of the camera device 10 conforms to various communication protocols and communication standards, and has communication means corresponding to a data transmission path such as a coaxial cable or USB. Therefore, by adopting a configuration in which the communication unit 21 communicates with the camera device 10 by the communication means of the external communication module 13, it is not necessary to provide a dedicated communication means for the external communication module 13, and the cost can be reduced.

In the present embodiment, the camera device 10 that is the target of the system construction device 20 includes modules 11 to 13 having three different functions, and each module has PLDs 11a, 12a, and 13a that can mount programs. did. On the other hand, the system construction device 20 can also set a camera device configured by a module different from the above combination as a system construction target. For example, as shown in FIG. 7, the camera device 110 is configured by selecting the imaging module 111 and the external communication module 113 one by one from among three or more modules having different functions and detachably connecting them. It may be.

  The imaging module 111 is a module that images a subject and acquires image data, and includes a PLD 111a, a memory unit 11b, and an image sensor 11c, as shown in FIG.

As described above, the imaging module 111 may be configured to have an image processing function equivalent to or simpler than the image processing module by an image processing program installed in the PLD 111a.

  The external communication module 113 is a module that communicates with the control device 2 that is an external device, and includes a memory unit 13b, an interface IC 13c, and a communication IC 113d as shown in FIG. The communication IC 113d can communicate with each other by a common signal shared between the modules. The communication IC 113d is interposed between the PLD 111a and the memory unit 13b of the imaging module 111 and between the PLD 111a and the interface IC 13c, thereby communicating an imaging command and image data between the control device 2 and the PLD 111a. It is possible. Here, the device driver of the interface IC 13 c is mounted on the PLD 111 a of the imaging module 111. As a result, the operation of the interface IC 13c is controlled by the PLD 111a of the imaging module 111 via the communication IC 113d. As described above, the camera apparatus 110 has a configuration in which the external communication module 113 does not have a circuit element such as a PLD, and the imaging module 111 controls the image processing and external communication in an integrated manner.

  In this modification, the system construction device 20 is targeted for the camera device 110 having the above-described configuration. In such a case, in the system construction device 20, in the preparation step (S10), the camera device 110 is configured by two modules, and acquires the function and hardware information for each module. Then, the system construction device 20 displays a program that can be installed in the PLD 111a on the display unit 24 based on the hardware information. Thereafter, image processing simulation or program suitability is determined as necessary, and the program is transferred to the PLD 111a via the communication unit. Thereby, the PLD 111a is defined as a logic circuit corresponding to a program, and can be driven so as to exhibit a predetermined function. In this way, the implementation of the program by the system construction device 20 is completed, and the system as the camera device 110 is constructed. As described above, if at least one of the plurality of modules constituting the camera device is provided with a circuit element capable of mounting a program, the system construction device 20 can construct the system for the camera device.
