Description

[Technical Field]

[0001] The present technology relates to an information processing device, an information display system, and an information display method, and particularly to a technical field related to displaying device status information that is information indicating the status of a device. [Background technology]

[0002] Generally, electronic devices such as cameras and audio equipment have the ability to display information indicating the status of the device (hereinafter referred to as "device status information"), such as the device's operating status and setting status (information indicating the current settings), allowing the user to check the status of the device.

[0003] Incidentally, the following Patent Document 1 can be cited as a related prior art.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-63320 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, the device status information is generally displayed on a display mounted on the device or on a display of another device associated with the device, such as a remote controller. However, in either case, the device status information is displayed on a specific display device, making it difficult for the user to display the device status information at any desired location.

[0006] Furthermore, since the area for displaying device status information is limited, it is desirable that the device status information be displayed so that only items that the user wishes to check can be displayed.

[0007] The present technology has been made in view of the above circumstances, and aims to enable device status information that a user wishes to check to be displayed at a location that the user desires. [Means for solving the problem]

[0008] The information processing device according to the present technology is provided with a transmission processing unit that performs processing to transmit device status information relating to a selected item to the external device that made the request in response to a request for device status information relating to the selected item from an external device via code information indicating the selected item, which is an item selected by a user for device status information representing the state of the device. Code information refers to a system of symbols used to express information. The term "symbol" here refers to a concept that includes not only marks and pictures, but also letters, numbers, etc. As described above, by using code information indicating the items selected by the user, it is possible to transmit to an external device only the device status information that the user wishes to check. Furthermore, by transmitting the device status information corresponding to the requesting device in response to a request made via the code information, it is possible to select any device to receive and display the transmitted device status information. In other words, it is possible to display the device status information in any location.

[0009] The information processing device according to the present technology described above can be configured to include a code information generating unit that generates code information indicating the selection item based on the user's operation. This makes it possible to eliminate the need for communication with other devices when generating code information.

[0010] In the information processing device according to the present technology described above, the external device can be configured to repeatedly make the request, and the transmission processing unit can be configured to acquire and transmit the device status information for each request from the external device. This makes it possible to transmit device status information in near real time. Here, near real time does not mean strictly real time, but is a concept that also includes instantaneous, simultaneous, real time, or any of these with various delay times.

[0011] The information display system according to the present technology is an information display system having at least an information processing device and a display device, and includes: a code information generation unit that generates code information indicating a selection item, which is an item selected by a user for device status information that represents the status of the information processing device; a code information output unit that outputs the code information generated by the code information generation unit; a request unit that is provided in the display device and reads the code information output by the code information output unit and requests the information processing device to transmit device status information related to the selection item indicated by the code information; a transmission processing unit that is provided in the information processing device and performs processing to transmit device status information related to the selection item to the display device in response to the request; and a display processing unit that is provided in the display device and performs processing to display the device status information transmitted by the transmission processing unit. Such an information display system according to the present technology also provides the same effects as the information processing device according to the present technology described above.

[0012] In the information display system according to the present technology, the code information output unit may be configured to print out the code information. This allows a print medium such as paper on which code information is printed to be placed at any position, and the code information can be displayed at any position desired by the user.

[0013] In the information display system according to the present technology, the code information output unit may be configured to display and output the code information. That is, the code information is displayed on a display device.

[0014] In the information display system according to the present technology described above, the code information generating unit may be provided in the display device. This allows the display device to accept operations related to the generation of code information, such as the selection of an item of device status information that the user wishes to display.

[0015] In the information display system according to the present technology, the display processing unit can be configured to switch the display mode of the device status information depending on the type of the device status information. This makes it possible to display device status information in an appropriate manner according to the type of information, for example, by displaying the amount as a bar for device status information that represents the device status as a quantity, such as remaining battery power, and by displaying device status information that represents the recording / playback operation state, such as REC / PLAY / standby, with a mark corresponding to each state (for example, a red circle for REC, a right-pointing triangle for PLAY, etc.).

[0016] In the information display system according to the present technology, the display processing unit It is possible to configure the device so that the device status information is superimposed on a captured image of the code information in order to read the code information. This allows the display device to be directed in the direction of the display position of the code information (the camera provided on the display device for reading the code information is directed in that direction), thereby making it possible to display the device status information to the user.

[0017] In the information display system according to the present technology described above, the display processing unit can be configured to perform processing to display the device status information at a position on the captured image determined based on the position of the code information in the captured image. This makes it possible to display the device status information at a position on the captured image that has a predetermined positional relationship with the position of the code information, such as a position that does not overlap with the code information or a position that overlaps with the code information.

[0018] In addition, the information display method related to the present technology is an information display method in an information display system having at least an information processing device and a display device, which generates code information indicating a selection item that is an item selected by a user for device status information that represents the status of the information processing device, outputs the generated code information, the display device reads the output code information and requests device status information related to the selection item indicated by the code information from the information processing device, the information processing device performs a process of transmitting device status information related to the selection item to the display device in response to the request, and the display device performs a display process of the transmitted device status information. This information display method also provides the same effects as the information processing device and information display system according to the present technology described above.

[0020] The embodiments will be described below in the following order. <1. First embodiment> [1-1. System configuration example] [1-2. Information display method as an embodiment] [1-3. Processing Procedure] 2. Second Embodiment <3. Modifications> <4. Summary of the embodiment> <5. This technology>

[0021] <1. First embodiment> [1-1. System configuration example] FIG. 1 is a block diagram showing an example of the configuration of an information display system 100 according to an embodiment of the present technology. The information display system 100 includes at least an imaging device 1, a code output device 2, and a mobile terminal device 3. The imaging device 1 is an embodiment of an information processing device according to the present technology, and the mobile terminal device 3 is an embodiment of a display device according to the present technology.

[0022] The imaging device 1 is configured as, for example, a digital video camera and is capable of generating moving image data as captured image data. In this example, the imaging device 1 is, for example, a commercial camera, and the environment in which the imaging device 1 is used is assumed to be a movie shooting location or the like.

[0023] The code output device 2 is configured as a device that outputs code information such as a QR code (registered trademark) described later. Specific device forms of the code output device 2 include, for example, a device form as a printer that prints out code information, and a device form as a display that displays and outputs code information.

[0024] The mobile terminal device 3 is a portable (portable) electronic device expected to be used by a user of the information display system 100, and has at least a display (display device) capable of displaying images and a function for reading code information. Specific device forms of the mobile terminal device 3 include, for example, a smartphone, a tablet terminal, AR glasses (AR: Augmented Reality), a notebook personal computer, and the like.

[0025] The information display system 100 is configured to enable data communication between the imaging device 1 and the code output device 2, and between the imaging device 1 and the mobile terminal device 3. In this example, the imaging device 1, the code output device 2, and the mobile terminal device 3 are capable of mutual data communication via a network 4. The network 4 may be, for example, a LAN (Local Area Network) or the Internet. In addition, in order to enable data communication between the imaging device 1 and the code output device 2, and between the imaging device 1 and the mobile terminal device 3, it is not necessary to adopt a configuration in which the imaging device 1, the code output device 2, and the mobile terminal device 3 are connected to the network 4 as described above.

[0026] FIG. 2 is a block diagram showing an example of the internal configuration of the imaging device 1. As shown in FIG. The imaging device 1 includes an imaging unit 10, a camera signal processing unit 11, a recording / playback control unit 12, a display unit 13, a communication unit 14, an operation unit 15, a control unit 16, and a bus 17, and is configured to capture an image of a subject and record the image data as a moving image or a still image on a recording medium. The camera signal processing unit 11 , recording / playback control unit 12 , display unit 13 , communication unit 14 , operation unit 15 , and control unit 16 are capable of mutual data communication via a bus 17 .

[0027] The imaging unit 10 includes a camera optical system having lenses such as a cover lens, a zoom lens, and a focus lens, a shutter, an aperture mechanism, and an imaging element such as a CMOS (Complementary Metal Oxide Semiconductor) type or a CCD (Charge Coupled Device) type that receives light from a subject that enters through the camera optical system. The imaging unit 10 performs processes such as CDS (Correlated Double Sampling) and AGC (Automatic Gain Control) on the electrical signals obtained by photoelectrically converting the light received by the imaging element, and then performs A / D (Analog / Digital) conversion on the electrical signals, and outputs the captured image signals as digital signals to a camera signal processor 11 at a subsequent stage.

[0028] The camera signal processing unit 11 is configured as an image processor, for example, using a DSP (Digital Signal Processor), etc. The camera signal processing unit 11 performs various types of signal processing on the digital signal (captured image signal) from the imaging unit 10. For example, as camera processes, the camera signal processing unit 11 performs preprocessing, synchronization processing, YC generation processing, resolution conversion processing, codec processing, etc. Pre-processing involves clamping the R, G, and B black levels to a predetermined level on the captured image signal from the imaging unit 10, as well as correction between the R, G, and B color channels. Synchronization involves color separation, which ensures that the image data for each pixel contains all R, G, and B color components. For example, in the case of an image sensor using a Bayer array color filter, demosaic processing is performed as the color separation process. YC generation involves generating (separating) a luminance (Y) signal and a color (C) signal from the R, G, and B image data. Resolution conversion involves executing resolution conversion on image data that has undergone various signal processes. In the codec process, the image data that has been subjected to the various processes described above is subjected to encoding and file generation for recording or communication, for example. In the codec process of this example, it is possible to generate moving image files in formats such as MPEG-2 (MPEG: Moving Picture Experts Group) and H.264. It is also possible to generate still image files in formats such as JPEG (Joint Photographic Experts Group), TIFF (Tagged Image File Format), and GIF (Graphics Interchange Format).

[0029] The recording and playback control unit 12 performs recording and playback on a recording medium such as a nonvolatile memory, for example, and performs processing to record image files such as moving image data and still image data, thumbnail images, and the like on the recording medium. There are various possible actual forms for the recording and playback control unit 12. For example, the recording and playback control unit 12 may be configured as a flash memory and its write / read circuit built into the imaging device 1, or may be in the form of a card recording and playback unit that performs recording and playback access to a recording medium that can be attached to or detached from the imaging device 1, such as a memory card (portable flash memory, etc.). The recording and playback control unit 12 may also be realized as an HDD (Hard Disk Drive) built into the imaging device 1.

[0030] The display unit 13 is a display unit that displays various information to the photographer, and is, for example, a display panel or viewfinder using a display device such as a liquid crystal panel (LCD: Liquid Crystal Display) or an organic EL (Electro-Luminescence) display that is arranged on the housing of the imaging device 1. The display unit 13 executes various displays on the display screen based on instructions from the control unit 16. For example, the display unit 13 displays a reproduced image of image data read from a recording medium by the recording and reproduction control unit 12. Furthermore, image data of the captured image that has been resolution-converted for display by the camera signal processing unit 11 is supplied to the display unit 13, and the display unit 13 may display the captured image based on the image data of the captured image in response to an instruction from the control unit 16. This causes a so-called through image (monitoring image of the subject), which is the captured image during composition confirmation, to be displayed.

[0031] Furthermore, based on instructions from the control unit 16, the display unit 13 displays various operation menus, icons, messages, etc., that is, GUI (Graphical User Interface), on the screen.

[0032] The communication unit 14 performs data communication and network communication with external devices via wire or wirelessly. For example, it is possible to transmit and output captured image data (still image files and moving image files) to an external display device, recording device, playback device, or the like. The communication unit 14 also communicates via a predetermined network such as the Internet or a LAN, and is capable of transmitting and receiving various data to and from servers, terminals (for example, the mobile terminal device 3), and the like on the network.

[0033] The operation unit 15 collectively refers to input devices that allow the user to input various operations. Specifically, the operation unit 15 refers to various operators (keys, dials, touch panel, touch pad, etc.) provided on the housing of the imaging device 1. The operation unit 15 detects the operation of the user, and sends a signal corresponding to the input operation to the control unit 16 .

[0034] The control unit 16 is configured to include a microcomputer (arithmetic processing device) equipped with a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The ROM of the control unit 16 stores an OS (Operating System) for the CPU to control each unit, application programs for various operations, firmware, etc. The RAM of the control unit 16 is used as a working area for the CPU to process various data, and for temporarily storing data, programs, etc.

[0035] The control unit 16 performs overall control of the imaging device 1 by causing the CPU to execute a program stored in the ROM or the like. For example, the control unit 16 controls the shutter speed of the imaging unit 10 and instructs various signal processing in the camera signal processing unit 11. The control unit 16 also controls the operations of the necessary units for imaging operations and recording operations in response to user operations, playback operations of recorded image files, user interface operations, etc. Furthermore, the control unit 16 instructs the imaging unit 10 to perform operations such as zoom, focus, and aperture adjustment in the camera optical system.

[0036] FIG. 3 is a block diagram showing an example of the internal configuration of the mobile terminal device 3. As shown in FIG. 3, a CPU 31 of the mobile terminal device 3 executes various processes in accordance with a program stored in a ROM 32 or a program loaded from a storage unit 39 (described later) into a RAM 33. The RAM 33 also stores data necessary for the CPU 31 to execute various processes, as appropriate. The CPU 31, ROM 32, and RAM 33 are interconnected via a bus 34. An input / output interface 35 is also connected to this bus 34.

[0037] An input unit 36 ​​consisting of operators and operation devices is connected to the input / output interface 35. For example, the input unit 36 ​​may be various operators and operation devices such as a touch panel, a mouse, a keyboard, a touchpad, keys, a dial, a remote controller, etc. The input unit 36 ​​detects a user operation, and the CPU 31 interprets a signal corresponding to the input operation.

[0038] Furthermore, the input / output interface 35 is connected to a display unit 37 made up of an LCD or an organic EL panel, and an imaging unit 38. The display unit 37 is configured as a display device capable of displaying images, and is a display device provided in the housing of the mobile terminal device 3, for example. The display unit 37 displays various images, captured images obtained by the imaging unit 38, and the like on the display screen based on instructions from the CPU 31. Furthermore, the display unit 37 displays various operation menus, icons, messages, and the like, that is, a GUI (Graphical User Interface), based on instructions from the CPU 31.

[0039] The imaging unit 38 includes an imaging element of, for example, a CMOS type or a CCD type, and obtains a digital image signal as a signal representing an image of an object.

[0040] A storage unit 39 including a hard disk, solid-state memory, etc., and a communication unit 40 for communicating with external devices are connected to the input / output interface 35. The communication unit 40 performs communication processing via a network such as a LAN or the Internet, and communicates with various devices via wired / wireless communication, bus communication, etc. This communication unit 40 enables the mobile terminal device 3 (CPU 31) to perform data communication with the imaging device 1 and the code output device 2 via the network 4 shown in FIG. 1.

[0041] A drive 42 is also connected to the input / output interface 35. A removable recording medium 41, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately attached to the drive 42. The drive 42 can read various data (e.g., images, computer programs, etc.) from the removable recording medium 41. The read data is stored in the storage unit 39, and images included in the data are output on the display unit 37. Furthermore, a computer program read from the removable recording medium 41 is installed in the storage unit 39 as needed.

[0042] [1-2. Information display method as an embodiment] Hereinafter, an information display method according to an embodiment will be described with reference to FIGS. Fig. 4 is a functional block diagram showing functions of the information display system 100, Fig. 4A is a functional block diagram showing functions of the control unit 16 in the imaging device 1, and Fig. 4B is a functional block diagram showing functions of the CPU 31 of the mobile terminal device 3. Note that Fig. 4 shows only functions related to the information display method according to the embodiment, extracted from the various functions of the control unit 16 and the CPU 31.

[0043] In FIG. 4A, the control unit 16 has functions as an item selection receiving unit F1, a code information generating unit F2, a state information managing unit F3, and a transmission processing unit F4. The item selection receiving unit F1 receives a selection of which item of device status information Is, which is information indicating the status of the imaging device 1, is to be displayed.

[0044] Here, the device status information Is can be roughly divided into setting status information Iss, which indicates the setting status of the target device, and operation status information Ism, which indicates the operation status. In this example where the target device is the imaging device 1, specific examples of the setting state information Iss include the frame rate, recording format (for example, MPEG / H.264), F-number, and system frequency. Specific examples of the operating status information Ism include the recording / playback operating status (PLAY / REC / standby), the load status (for example, the load status of the CPU in the camera signal processing unit 11 or the control unit 16), the remaining media capacity (the remaining recordable capacity of the recording medium to which the captured image is to be recorded by the recording / playback control unit 12), and the remaining battery capacity (the remaining capacity of the battery used as the power source for the imaging device 1).

[0045] The item selection receiving unit F1 receives a selection from the user regarding the items of the various types of device status information Is such as those exemplified above.

[0046] The code information generating unit F2 generates code information indicating the selected item, which is the item selected by the user. Code information means a symbol system for expressing information. The "symbol" here is a concept that includes not only marks and pictures but also letters, numbers, etc. There are many possible examples of code information, including QR Code (registered trademark), barcodes, and text information such as URI (Uniform Resource Identifier). In particular, in this example, information that can be output as visual information is used as code information (information that can be printed out or displayed, as described below).

[0047] The status information management unit F3 manages the latest information regarding device status information Is that is a candidate for selection by the user (that is, device status information Is that is a candidate for selection when an item selection is received). The specific processing of this state information management unit F3 will be explained later.

[0048] The transmission processing unit F4 performs a process of transmitting device status information Is related to the selected item to the requesting external device in response to a request for device status information Is related to the selected item from the external device (in this example, the mobile terminal device 3) via the code information generated by the code information generation unit F2. In this example, the mobile terminal device 3 has an imaging unit 38 and is capable of reading the code information. In this example, the transmission processing unit F4 performs processing to transmit the device status information Is related to the selected item to the mobile terminal device 3 in response to the request (see request unit F5 below) made by the mobile terminal device 3 in response to reading the code information.

[0049] In FIG. 4B, the CPU 31 has functions as a request unit F5 and a display processing unit F6. The request unit F5 reads the code information output by the code information output unit, and requests the information processing device (the imaging device 1 in this example) to transmit device status information Is related to the selection item indicated by the code information. The code information output unit corresponds to the code output device 2 in this example. The display processing unit F6 performs display processing of the device status information Is transmitted by the transmission processing unit F4 in the imaging device 1 (control unit 16). As will be described later, in this example, the device status information Is is displayed on the display unit 37 of the mobile terminal device 3 in a superimposed manner on a captured image of the code information captured for reading the code information.

[0050] FIG. 5 is an explanatory diagram of specific operations realized in the information display system 100 by the various functions described above. First, the imaging device 1 performs the procedure shown in FIG. <1> Steps from <3> The following operation is performed. procedure <1> In this step, the user selects an item that he or she wants to display on the screen of the image capture device 1. <2> Then, generate code information that indicates the selected item. <1> corresponds to the item selection receiving section F1 described above, and the procedure <2> corresponds to the code information generating unit F2. And the procedure <3> Then, an instruction to output the code information is given. In this example, the code information is output by the code output device 2 as a printer. <3> Then, an instruction is given to the code output device 2 to print out the code information. Upon receiving the instruction, the code output device 2 performs the procedure shown in the figure. <4> As shown in the figure, the code information is printed out in response to the instruction.

[0051] FIG. 6 shows an example of screen transitions related to item selection of device status information Is. 6A shows an example of a menu screen G1 displayed on the display unit 13 of the imaging device 1. As shown in the figure, the menu screen G1 displays menu items related to various settings and operational instructions for the imaging device 1, and one of the menu items displays an item for instructing the generation of code information ("QR code generation" in the figure). In this example, an item on the menu screen G1 is selected using a cursor CR shown in the figure. The user can move the cursor CR by operating the operation unit 15, and can instruct the selection of the item pointed to by the cursor CR by performing a predetermined operation such as operating the enter button when the cursor CR is in a position pointing to one of the items.

[0052] FIG. 6B shows an example of an item selection screen G2 that is displayed on the display unit 13 in response to the selection of the "QR code generation" item in FIG. 6A. The item selection screen G2 displays a list of items of device status information Is that are candidates for selection, from which a desired item can be selected. Specifically, the item selection screen G2 in this example has a check box for each item, and the user can select an item by checking the check box. In this case, an item can be selected by performing a predetermined operation, such as operating the enter button while the cursor CR is positioned on the check box of the item desired to be selected. As illustrated in the figure, in this example, it is possible to select not only a single item but also multiple items.

[0053] The item selection screen G2 is provided with a selection completion button B1 and a cancel button B2. The selection completion button B1 is a button for instructing completion of item selection. The cancel button B2 is a button for canceling the generation of code information indicating the selected item, and when the cancel button B2 is operated, the screen display of the display unit 13 switches from the item selection screen G2 to the menu screen G1. Note that operation instructions for buttons arranged on the screen, such as the selection completion button B1 and the cancel button B2, are given by operating the cursor CR. That is, when a predetermined operation, such as the operation of the enter button, is performed while a certain button is pointed to by the cursor CR, the control unit 16 recognizes that the button has been operated.

[0054] FIG. 6C shows an example of a code display screen G3 that is displayed in response to the selection completion button B1 being operated. The code display screen G3 displays the code information generated by the code information generating unit F2, specifically, the QR code information in this example. In response to the operation of the selection completion button B1, the code information generation unit F2 generates a QR code indicating the item selected by the user. Here, the code information is generated as information including an identifier for identifying the selected item, for example. In this example, the imaging device 1 manages each item of device status information Is, such as recording / playback operation status, load status, system frequency, recording format, etc., with a corresponding identifier. In response to operation of the selection completion button B1, the code information generation unit F2 in this example generates, as code information, information obtained by encoding an identifier corresponding to an item selected by the user from among these identifiers.

[0055] The code display screen G3 is provided with an output button B3 for instructing the output of the generated code information. In response to the operation of this output button B3, the control unit 16 instructs the code output device 2 to print out the generated code information.

[0056] In this example, it is assumed that the code information is output as a printout, but the code information can also be output as a display output using a predetermined display device. In this case, the control unit 16 issues a display output instruction to the display device as an output instruction for the generated code information. In this case, it may be possible to select either a printer or a display device as the output destination of the code information, and in that case, the selection of the output destination of the code information may be accepted on the setting screen of the display unit 13. It is also possible to accept the selection of the output size of the code information (at least one of the size for printing out and the size for displaying) on ​​the setting screen displayed on the display unit 13.

[0057] Returning to the explanation of Figure 5. In this example, the printed code information is arranged at a desired position by the user (see the procedure in the figure). <5> In this example, the code information is information indicating an item of the device status information Is of the imaging device 1, and therefore, it may be arranged in a position near the imaging device 1, for example. In this example, the process up to arranging the code information at a desired position is a preparatory stage for causing the mobile terminal device 3 to display the device status information Is.

[0058] procedure <6> Steps from <8> This is the procedure of the mobile terminal device 3. First, the procedure <6> Then, the code information is captured and read. <5> The code information arranged in step 3 is imaged and read by the imaging unit 38. procedure <7> Then, the image capture device 1 is requested to provide the device status information Is of the item indicated by the code information. procedure <8> In the mobile terminal device 3, the device status information Is received in response to the request is superimposed on the code captured image. Here, the code captured image means an image captured of code information in order to read the code information. When the code information is read, the code captured image is displayed on the display unit 37 of the mobile terminal device 3. The device status information Is received from the imaging device 1 is superimposed on the code captured image displayed in this way. A specific example of displaying the device status information Is will be described later.

[0059] Here, in the imaging device 1, the transmission processing unit F4 acquires the device status information Is corresponding to the time when the request was made in response to a request (transmission request) for device status information Is through the code information as described above, and performs processing to transmit the acquired device status information Is to the mobile terminal device 3. At this time, the transmission processing unit F4 performs processing to acquire the relevant device status information Is from the list of device status information Is managed by the status information management unit F3 described above, and transmits the information to the mobile terminal device 3.

[0060] FIG. 7 is a diagram showing an example of the state management information I1 generated by the state information management unit F3. The status information management unit F3 manages the latest information of the device status information Is for each item using this status management information I1. For example, for the recording / playback operation status items in the figure, when a switch is made between REC, PLAY, and standby, the status information after the switch is stored in the status management information I1. Similarly, for the system frequency and recording format in the figure, when a setting switch is made, information indicating the status after the switch (for example, the frequency after the switch for the system frequency, and the format after the switch for the recording format) is stored in the status management information I1. Furthermore, the latest information on the load state, remaining battery capacity, and remaining media capacity shown in the figure is acquired, for example, at regular intervals and stored in the status management information I1.

[0061] In response to a request for device status information Is via code information, the transmission processing unit F4 acquires the requested device status information Is from the device status information Is stored in such status management information I1 and transmits it to the mobile terminal device 3.

[0062] In addition, with regard to device status information Is, such as load status and system frequency, whose information content may change relatively frequently, it is possible to not manage the information in the status management information I1, but to obtain the latest information in response to a request from the mobile terminal device 3.

[0063] FIG. 8 is an explanatory diagram showing an example of display of device status information Is on the mobile terminal device 3. In FIG. In this example, the device status information Is is displayed at a position on the captured code image that is determined based on the position of the code information in the captured code image. FIG. 8A shows an example in which information on the recording / playback operation status (shown as "REC" in the figure) is displayed as device status information Is, and FIG. 8B shows an example in which information on the remaining media capacity is displayed as device status information Is. As illustrated in these figures, in this example, the device status information Is is displayed diagonally below and to the right of the code information in the code image. Note that this relationship between the position of the code information and the position of the device status information Is is merely an example, and various other relationships are possible. For example, the device status information Is may be displayed at a position where the horizontal or vertical centers of the code information and the device status information Is coincide with each other, or the device status information Is may be displayed at a position where it covers all or part of the code information.

[0064] As described above, by displaying the device status information Is at a position based on the position of the code information in the code image, the device status information Is can be displayed at a position that is considered appropriate based on the position of the code information. In particular, as illustrated in Figure 8C, when multiple pieces of code information are captured in a captured image, each piece of device status information Is is displayed at a position based on the corresponding piece of code information, allowing the user to intuitively understand which piece of code information the device status information Is corresponds to.

[0065] Furthermore, in this example, the display processing unit F6 switches the display mode of the device status information Is depending on the type of the device status information Is. Specifically, as illustrated by comparing Figures 8A and 8B, a mark indicating the type of operation status (specifically, a red circle for REC) is displayed for information on the recording / playback operation status, and a bar indicating the remaining capacity is displayed for information on the remaining media capacity. Note that, regarding the display of the recording / playback operation status, for example, a right-pointing triangle mark may be displayed for PLAY, and a square mark may be displayed for STANDBY.

[0066] Although the above example shows a case where a bar display is used to indicate the remaining media capacity, such a bar display can also be applied to device status information Is that quantitatively indicates the status of the device, such as the remaining battery capacity or load state. In this case, the representation of the quantity is not limited to the bar display shown as an example, and other graphical representations such as a meter display may also be used.

[0067] The device status information Is may also be displayed in a manner that allows transparency. For example, it may be displayed as a semi-transparent display object, allowing the background to be seen through.

[0068] Here, in this embodiment, a method is adopted in which the device status information Is is requested from the imaging device 1 through code information, but the output code information can be displayed at any position. For example, the code information can be displayed at any position, such as by placing a sheet of paper on which the code information is printed out at any position, or by displaying the code information on a desired display device outside the imaging device 1. The advantage of adopting a method in which the device status information Is is requested from the imaging device 1 through code information is that the code information can be displayed at any position in this way. For example, when displaying the remaining battery capacity as device status information Is, the remaining battery capacity is closely linked to the battery case, and if the code information is placed near the battery case and the remaining battery capacity is displayed when the code information reading device (in this example, the portable terminal device 3) is pointed toward the battery case, usability for the user can be improved. By adopting a method of requesting device status information Is from the imaging device 1 through code information, it is possible to display the code information in an appropriate position according to the type of device status information, such as displaying the code information near the battery case in the above example of remaining battery capacity. This allows the user to display the device status information Is by pointing the reading device at a position related to the device status information they want to check, thereby improving usability for the user in checking the desired device status information Is.

[0069] [1-3. Processing Procedure] An example of a specific processing procedure for realizing the information display method according to the embodiment described above will be described with reference to the flowcharts of FIGS. Fig. 9 is a flowchart showing the processing of the state information management unit F3 in the imaging device 1. The control unit 16 executes the processing shown in Fig. 9 for each piece of device state information Is to be managed by the state management information I1 (i.e., each piece of device state information Is that is a selection candidate on the item selection screen G2).

[0070] 9, in step S101, the control unit 16 waits for the timing of information update for the target device status information Is. For example, as illustrated above, the timing of information update for the recording / playback operation state is the timing of switching between REC / PLAY / standby, and the timing of information update for setting status information Iss such as the system frequency and recording format is the timing of information update when the setting is switched. Furthermore, the timing of information update for the load state, remaining battery capacity, and remaining media capacity is, for example, at regular intervals. In this way, in step S101, the control unit 16 waits for the arrival of the information update timing determined according to the type of device status information Is.

[0071] If it is time to update information, the control unit 16 proceeds to step S102, acquires the latest information about the target device status information Is, and then performs processing to update the status management information I1 in the following step S103. That is, processing is performed to update the target device status information Is stored in the status management information I1 to the latest information acquired in step S102. After executing the process of step S103, the control unit 16 ends the series of processes shown in FIG.

[0072] In the above example, different information update timings are set depending on the type of device status information Is, but the information update timings can also be set to a common timing regardless of the device status information Is. Furthermore, when different information update timings are used for different types of device status information Is, for example, items with relatively low frequency of information changes, such as recording / playback operation status, may be updated at times according to status changes, while items with relatively high frequency of information changes, such as load status and remaining media capacity, may be updated at fixed times, such as every second.

[0073] Here, it is not necessary to manage all of the device status information Is using the status management information I1. For example, it is possible to use a method in which only information with low frequency of status changes is managed using the status management information I1, and information with high frequency of status changes is updated and transmitted when a request is made from the mobile terminal device 3. Alternatively, a method may be adopted in which the latest information is acquired and transmitted for all of the device status information Is at the timing when a request is made from the mobile terminal device 3 in this manner.

[0074] Fig. 10 is a flowchart showing the processing of the item selection receiving unit F1 and the code information generating unit F2 in the imaging device 1. It is assumed that the item selection screen G2 is already displayed on the display unit 13 when the processing shown in Fig. 10 starts. First, in step S110, the control unit 16 performs an item selection reception process, i.e., a process of updating the display contents of the item selection screen G2 in response to a user's operation input (for example, a process related to moving the cursor CR or adding a check mark to a check box). In the next step S111, the control unit 16 determines whether the selection is complete, specifically, whether the selection complete button B1 has been operated. If it is determined that the selection complete button B1 has not been operated and the selection is not complete, the control unit 16 returns to step S110. As a result, the state of accepting item selection by the user continues until the selection complete button B1 is operated.

[0075] If it is determined in step S111 that the selection is complete, the control unit 16 proceeds to step S112 and generates code information (a QR code in this example) indicating the selected item. Although not shown in the figure, in response to generating the code information in this way, the control unit 16 performs processing to display a code display screen G3 including an image of the generated code information on the display unit 13.

[0076] In step S113 following step S112, the control unit 16 waits for an instruction to output code information, specifically, for operation of the output button B3 on the code display screen G3.

[0077] If it is determined that the output button B3 has been operated and an instruction to output the code information has been issued, the control unit 16 proceeds to step S114, and issues an instruction to the code output device 2 to print out the generated code information as an instruction to output the code information, and then completes the series of processes shown in Figure 10.

[0078] 11 is a flowchart showing the processing of the request unit F5 and the display processing unit F6 in the mobile terminal device 3, and the processing of the transmission processing unit F4 in the imaging device 1. In FIG. 11, the processing shown for the mobile terminal device 3 is executed by the CPU 31, and the processing shown for the imaging device 1 is executed by the control unit 16.

[0079] First, in step S201, the CPU 31 of the mobile terminal device 3 waits until a code imaging instruction is made. In this example, an application (application program) for reading code information and displaying device status information Is is pre-installed in the mobile terminal device 3, and the code imaging instruction in this case is defined as an operation by the user to start the application. Therefore, in step S201 in this example, the CPU 31 waits for the operation to start the application. When the application is started, the imaging unit 38 is started and becomes ready to read the code information, and the display unit 37 starts displaying the image captured by the imaging unit 38 .

[0080] If it is determined in step S201 that a code image capture instruction has been received, the CPU 31 determines in step S202 whether or not code information has been detected. If code information has not been detected, the CPU 31 proceeds to step S203 to determine whether or not an end operation has been performed. The end operation here refers to, for example, an operation to end the above-mentioned app. If an end operation has not been performed, the CPU 31 returns to step S202. That is, steps S202 and S203 form a loop process that waits for either the detection of code information or the end operation. If it is determined in step S203 that a termination operation has been performed, the CPU 31 ends the series of processes shown in FIG.

[0081] If it is determined in step S202 that code information has been detected, the CPU 31 proceeds to step S204 and requests the imaging device 1 to transmit device status information Is relating to the selection item indicated by the code information. In this example, the imaging device 1 (control unit 16) manages each item of device status information Is using the identifier described above, and generates information indicating the identifier as code information. The mobile terminal device 3 reads this code information to obtain information on the identifier indicating the selected item. In step S204, the CPU 31 makes a transmission request to the imaging device 1 specifying the device status information Is to be transmitted using the identifier of the selected item obtained in this manner.

[0082] In the imaging device 1, the control unit 16 waits in step S121 for a transmission request from the mobile terminal device 3 side, which is made in step S204, and when the transmission request is received, the control unit 16 performs processing to acquire the corresponding device status information Is from the status management information I1 in step S122. That is, from the device status information Is stored in the status management information I1, the control unit 16 acquires the device status information Is identified by the identifier included in the transmission request from the mobile terminal device 3 side.

[0083] In step S123 following step S122, the control unit 16 performs a process of transmitting the device status information Is acquired in step S122 to the mobile terminal device 3 as a process of transmitting the device status information Is, and then ends the series of processes shown in FIG.

[0084] In the mobile terminal device 3, the CPU 31 waits for reception of the device status information Is transmitted in step S123 in step S205 following the above-mentioned step S204, and when the device status information Is is received, the process proceeds to step S206 to perform display processing of the device status information Is. That is, as described above with reference to Fig. 8, the display unit 37 displays the device status information Is superimposed on the captured code image. Note that a specific example of displaying the device status information Is in this example has already been explained, so a duplicate explanation will be avoided.

[0085] In response to the execution of the display processing of step S206, the CPU 31 determines in step S207 whether or not a termination operation has been performed. If it determines that a termination operation has not been performed, the CPU 31 returns to step S202. As a result, until a termination operation is performed, the determination of whether or not code information has been detected (S202), and the transmission request for device status information Is and display processing corresponding to the code information detected (S204 to S206) are repeatedly executed. In other words, as long as code information continues to be detected, the transmission request for device status information Is and display processing are repeatedly executed, and it becomes possible to successively reflect updated information (i.e., the latest information) in the display in response to updates of the device status information Is on the imaging device 1 side.

[0086] Furthermore, according to the loop process of steps S202 and S203, if the code information is no longer detected, the transmission request and display process of the device status information Is are no longer executed. In other words, if the code information cannot be detected, the display unit 37 no longer displays the device status information Is based on the code information.

[0087] If it is determined in step S207 that an end operation has been performed, the CPU 31 ends the series of processes shown in FIG.

[0088] In the information display system 100 of the embodiment, a user can generate multiple pieces of code information each indicating a different selection item by operating the imaging device 1, and can cause the code information to be printed out on different sheets of paper by the code output device 2. At this time, the printed out code information can be arranged (displayed) in different positions at the shooting site. For example, code information indicating the remaining battery charge item can be arranged in a position near the battery case (e.g., an external battery case) of the imaging device 1, and code information indicating the F-number item can be arranged in a position near the lens barrel of the imaging device 1. In this case where different code information is arranged at different positions, assume that the user points the mobile terminal device 3 toward certain code information (hereinafter referred to as first code information) to read the first code information, and the corresponding device status information Is is displayed on the code captured image of the first code information. From this state, if the user points the mobile terminal device 3 toward the second code information to read other code information (hereinafter referred to as second code information), the displayed first code information will frame out of the display screen. At this time, the first code information becomes unreadable (undetectable), and according to the processing of FIG. 11, the display of the device status information Is corresponding to the first code information will also end. When the second code information frames into the image captured by the imaging unit 38, the second code information is read, and the device status information Is corresponding to the second code information is displayed superimposed on the code captured image of the second code information.

[0089] Thus, according to the information display system 100, when multiple pieces of code information are arranged at intervals that do not fit simultaneously within the image capture frame of the imaging unit 38, the device status information Is to be displayed can be switched by changing the orientation of the mobile terminal device 3 (i.e., by changing the image capture direction of the imaging unit 38) to sequentially capture different pieces of code information within the image capture frame.

[0090] 2. Second Embodiment Next, a second embodiment will be described. In the second embodiment, the hardware configuration of the information display system 100 is the same as that of the first embodiment, and therefore a description thereof will be omitted.

[0091] In the second embodiment, the generation of code information indicating an item selected by the user is performed not by the imaging device 1 but by the portable terminal device 3 side. FIG. 12 shows an example of a specific operation procedure. First, the procedure <1> As shown in the figure, the user is prompted to select an item to be displayed via the screen of the mobile terminal device 3. In this case, the item selection screen G2 as exemplified in Fig. 6B is displayed on the display unit 37 of the mobile terminal device 3, and therefore item information of the device status information Is to be selected (for example, information on the item name and information on the identifier for each item as described above) is stored in advance in the mobile terminal device 3.

[0092] Next, the mobile terminal device 3 performs the procedure <2> As shown in the figure, code information indicating the selected item is generated, and the procedure <3> In step 100, an instruction to output code information is given to the code output device 2.

[0093] In addition, the procedure <4> and procedures <5> Since this is the same as in the case of FIG. 5, the explanation will be omitted. In addition, in the mobile terminal device 3, the procedure <6> and procedures <7> is the same as in the case of FIG. 5, so the explanation will be omitted.

[0094] In the imaging device 1, the procedure by the mobile terminal device 3 <7> If a request is made, the procedure <8> As shown in the figure, the device status information Is relating to the selected item is transmitted to the mobile terminal device 3 in response to the request.

[0095] In the mobile terminal device 3, the procedure <8> When the device status information Is transmitted in step 1 is received, <9> As shown in the figure, the received device status information Is is superimposed on the captured code image.

[0096] FIG. 13 is a functional block diagram for explaining the functions of the control unit 16 and the CPU 31 in the second embodiment. As shown in Fig. 13A, the control unit 16 in this case has the functions of a state information management unit F3 and a transmission processing unit F4. Also, as shown in Fig. 13B, the CPU 31 in this case has the functions of an item selection receiving unit F1, a code information generating unit F2, a request unit F5, and a display processing unit F6.

[0097] The processing of the state information management unit F3, transmission processing unit F4, request unit F5, and display processing unit F6 is the same as that described with reference to FIGS. 9 to 11, and therefore description thereof will be omitted. In addition, the processing of the item selection receiving unit F1 and the code information generating unit F2 in this case is the same as that described in FIG. 10 except that the execution entity changes from the control unit 16 to the CPU 31, so the description will be omitted.

[0098] By generating the code information on the mobile terminal device 3 side, it becomes possible to accept operations related to the generation of the code information, such as the selection operation of the item of device status information Is that you want to display, on the mobile terminal device 3 side rather than on the imaging device 1 side. Therefore, it is possible to eliminate the inconvenience of the user having to go to a place where he or she can operate the imaging device 1 in order to generate code information. In addition, when multiple users each want to generate code information, it is possible to prevent waiting for operations on the imaging device 1 (a waiting time until other users complete operations to generate code information).

[0099] <3. Modifications> Here, the embodiment is not limited to the specific example given above, and various modifications are possible. For example, as mentioned above, the code output device 2 can be configured as a display device, i.e., the mobile terminal device 3 can read the code information displayed on the display device. However, as an example of using the code output device 2 as a display device, the code output device 2 can be configured as a wristwatch-type display device such as a smartwatch, as shown in FIG. 14 . In this case, the code output device 2 is provided with a display unit 2a at a position corresponding to the dial of the wristwatch, and the display unit 2a can display the device status information Is. Note that a wristwatch-type display device such as a smartwatch may not have a function for connecting to a network 4 such as the Internet or a LAN, and may only be capable of short-range wireless communication with the mobile terminal device 3 via, for example, Bluetooth (registered trademark). Therefore, in this case, as illustrated in the second embodiment, it is desirable for the mobile terminal device 3 to issue an instruction to output the generated code information.

[0100] Furthermore, in the explanation so far, examples have been given in which the code output device 2 is configured separately from the imaging device 1 and the mobile terminal device 3, but the code output device 2 may also be configured integrally with the imaging device 1 or the mobile terminal device 3. For example, when the code information generation unit F2 is provided in the imaging device 1 as in the first embodiment and a printer is used as the code output device 2, it may be possible to adopt a configuration in which the printer is integrated with the imaging device 1. Similarly, when a printer is used as the code output device 2 and the code information generation unit is provided in the mobile terminal device 3 as in the second embodiment, it may be possible to adopt a configuration in which the printer is integrated with the mobile terminal device 3.

[0101] The code information can also be displayed on a display included in the imaging device 1. In this case, the code output device 2 is configured integrally with the imaging device 1.

[0102] The information display system 100 may also be configured to include a plurality of imaging devices 1. In this case, the user can generate code information for each imaging device 1 and have the mobile terminal device 3 read each piece of code information, thereby enabling the user to check the device status information Is of the plurality of imaging devices 1 on a single mobile terminal device 3. The information display system 100 can also be configured as a system provided with a plurality of portable terminal devices 3. In this case, it is conceivable that each staff member will be allowed to use a portable terminal device 3. This allows each staff member to check the desired device status information Is for the imaging device 1 of interest.

[0103] Furthermore, in the explanation so far, an example has been given in which the information processing device according to the present technology is the imaging device 1, but the information processing device according to the present technology can be widely and suitably applied to various electronic devices that can be expected to display device status information, such as audio devices such as recording devices, and industrial or consumer robotic devices.

[0104] <4. Summary of the embodiment> As described above, the information processing device (imaging device 1) according to the embodiment includes a transmission processing unit (F4) that performs processing to transmit device status information relating to a selected item to the requesting external device in response to a request for device status information relating to a selected item from an external device via code information indicating a selected item, which is an item selected by a user, for device status information (Is) representing the status of the device. As described above, by using code information indicating the items selected by the user, it is possible to transmit to an external device only the device status information that the user wishes to check. Furthermore, by transmitting the device status information corresponding to the requesting device in response to a request made via the code information, it is possible to select any device to receive and display the transmitted device status information. In other words, it is possible to display the device status information in any location. Therefore, according to the information processing device of the embodiment, it is possible to display the device status information that the user wishes to check at a location that the user desires.

[0105] Furthermore, the information processing device according to the embodiment includes a code information generating unit (F2) that generates code information indicating a selection item based on a user operation (see FIG. 4, first embodiment). This makes it possible to eliminate the need for communication with other devices when generating code information. Therefore, the processing load associated with generating code information can be reduced.

[0106] Furthermore, in the information processing device according to the embodiment, the external device repeatedly makes requests, and the transmission processing unit performs processing to acquire and transmit device status information for each request from the external device (see FIG. 11). This makes it possible to transmit status information as device status information in approximately real time. Therefore, it is possible to improve the accuracy of the device status information displayed to the user. Here, near real time does not mean only strict real time, but is a concept that also includes instantaneous, simultaneous, real time, or any of these with various delay times.

[0107] An information display system (100) as an embodiment is an information display system having at least an information processing device (imaging device 1) and a display device (mobile terminal device 3), and is equipped with a code information generation unit (F2) that generates code information indicating a selection item, which is an item selected by a user for device status information that represents the status of the information processing device, a code information output unit (code output device 2) that outputs the code information generated by the code information generation unit, a request unit (F5) that is provided in the display device and reads the code information output by the code information output unit and requests the information processing device to transmit device status information related to the selection item indicated by the code information, a transmission processing unit (F4) that is provided in the information processing device and performs processing to transmit device status information related to the selection item to the display device in response to the request, and a display processing unit (F6) that is provided in the display device and performs processing to display the device status information transmitted by the transmission processing unit (see Figures 4, 13, etc.). The information display system according to this embodiment also provides the same effects as the information processing device according to the above embodiment. Therefore, the device status information that the user wishes to check can be displayed at the location that the user desires.

[0108] In the information display system according to the embodiment, the code information output unit prints out the code information (see FIG. 5, etc.). This allows a print medium such as paper on which code information is printed to be placed at any position, and the code information can be displayed at any position desired by the user. Since it is not necessary to use a display device for the code information to display the code information at an arbitrary position, it is possible to eliminate the need for power consumption to maintain the display state of the code information. In this case, the code information can be displayed by simply attaching a piece of paper or the like on which the code information is printed to the desired location, which improves the freedom of selecting the location to display the code information (compared to using a code information display device).

[0109] Furthermore, in the information display system according to the embodiment, the code information output unit displays and outputs the code information. That is, the code information is displayed on a display device. When printing out code information, switching the code information to be displayed requires printing out new code information, but by displaying the code information on a display device, it is possible to easily switch the code information to be displayed.

[0110] Furthermore, in the information display system according to the embodiment, a code information generating unit is provided in the display device (see FIG. 13, second embodiment). This allows the display device to accept operations related to the generation of code information, such as the selection of an item of device status information that the user wishes to display. Therefore, it is possible to eliminate the inconvenience of the user having to go to a place where he or she can operate the information processing device in order to generate code information. Furthermore, when multiple users each want to generate code information, it is possible to prevent waiting for an operation of the information processing device.

[0111] In the information display system according to the embodiment, the display processing unit switches the display mode of the device status information depending on the type of the device status information (see FIG. 8, etc.). This makes it possible to display device status information in an appropriate manner according to the type of information, for example, by displaying the amount as a bar for device status information that represents the device status as a quantity, such as remaining battery power, and by displaying device status information that represents the recording / playback operation state, such as REC / PLAY / standby, with a mark corresponding to each state (for example, a red circle for REC, a right-pointing triangle for PLAY, etc.). Therefore, it is possible to improve the ease with which the user can check the device status information.

[0112] Furthermore, in the information display system according to the embodiment, the display processing unit performs processing for superimposing and displaying device status information on a captured image of the code information in order to read the code information (see FIG. 8, etc.). This allows the display device to be directed in the direction of the display position of the code information (the camera provided on the display device for reading the code information is directed in that direction), thereby making it possible to display the device status information to the user. Therefore, the user can display the code information at a position related to the device status information that the user wants to check, and then check the device status information by intuitively pointing the display device in the direction of the display position of the code information, thereby improving usability for the user.

[0113] Furthermore, in the information display system according to the embodiment, the display processing unit performs processing to display the device status information at a position on the captured image that is determined based on the position of the code information in the captured image (see FIG. 8, etc.). This makes it possible to display the device status information at a position on the captured image that has a predetermined positional relationship with the position of the code information, such as a position that does not overlap with the code information or a position that overlaps with the code information. Therefore, the device status information can be displayed at a position that is deemed appropriate based on the position of the code information. For example, when a plurality of pieces of code information are captured in a captured image, the user can intuitively understand which piece of code information the device status information corresponds to.
