<1. First Embodiment>
[Block configuration example of optical communication system]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram showing a configuration example of an optical communication system 100A according to an embodiment of the present invention. The optical communication system 100A includes a functional board 10 that generates predetermined functional information and a processing board 30 that performs predetermined processing on the functional information generated by the functional board 10. The functional substrate 10 is detachably attached to the processing substrate 30 and can be replaced with another functional substrate.

  The functional board 10 is an example of a transmission device and includes an optical communication unit 12. The optical communication unit 12 includes a light emitting unit 14, an optical transmission control unit 16, and a functional unit operation start instruction unit 18. The optical transmission control unit 16 includes, for example, a laser diode driver, generates a driving (bias) current, and supplies it to the light emitting unit 14. The light emitting unit 14 is composed of, for example, a laser diode or the like, and converts an electrical signal supplied from a pixel unit or the like (not shown) into an optical signal by using a drive current from the optical transmission control unit 16 to generate light on the processing substrate 30 side. Output to the communication unit 32. The functional unit operation start instructing unit 18 performs the operation of the functional substrate 10 based on communication availability information supplied from an optical communication establishment determining unit 60 of the processing substrate 30 to be described later and indicating communication establishment between the functional substrate 10 and the processing substrate 30. Let it begin.

  The processing board 30 is an example of a receiving device, and includes an optical communication unit 32, an optical communication establishment determination unit 60, a light emitting unit death determination unit 80, a user presentation unit 40, a user operation acquisition unit (operation acquisition unit) 42, and a display unit 44. And a light shielding / mechanism lock instruction section 72. The optical communication unit 32 includes a light receiving unit 34 and an average light reception level detecting unit 50. The light receiving unit 34 is composed of, for example, a photodiode, receives the optical signal emitted from the light emitting unit 14, converts it into an electrical signal, and supplies the converted electrical signal (optical signal) to the average received light level detection unit 50.

  The average received light level detection unit 50 calculates the average received light level of the optical signal received by the light receiving unit 34 and supplies it to the optical communication establishment determination unit 60. In this average light reception level detection unit 50, for example, an optical signal smoothed and noise-removed by an integration circuit is fed back to an amplifier circuit, thereby obtaining an average light reception level based on a stable optical signal.

  The optical communication establishment determination unit 60 is an example of a processing unit, and whether communication is established between the functional substrate 10 and the processing substrate 30 based on the average light reception level supplied from the average light reception level detection unit 50.

For example, the optical communication establishment determination unit 60 refers to the lookup table and determines whether communication is established between the light emitting unit 14 and the light receiving unit 34 based on the average light reception level acquired from the average light reception level detection unit 50. Judge whether or not. The lookup table corresponds to the average light reception level and communication availability information (○ (communication possible), × (communication impossible)) indicating whether or not communication is established between the light emitting unit 14 and the light receiving unit 34. For example, when it is determined that the average received light level exceeds a predetermined threshold value, it is determined that communication is possible with reference to the lookup table. After that, the optical communication establishment determining unit 60 supplies communication enable / disable information indicating whether communication is possible to the light emitting unit death determining unit 80, the user presenting unit 40, and the function unit operation start instructing unit 18 on the function board 10 side.

  The light emitting unit death determining unit 80 is an example of a processing unit. For example, when the optical communication establishment determining unit 60 determines that communication between the functional substrate 10 and the processing substrate 30 is possible, the light emitting unit 14 or It is determined whether the light receiving unit 34 is deteriorated or dead. This is because even when the optical communication establishment determining unit 60 determines that communication is possible, the light emitting unit 14 may be deteriorated because weak communication light is used when determining communication establishment. It is. Of course, even when it is determined that communication is not possible, the deterioration of the light emitting unit 14 or the like can be detected using the light emitting unit death determining unit 80 in order to identify the cause. As a method for determining deterioration of the light emitting unit 14, for example, the average light receiving level of the light emitting unit 14 acquired by the average light receiving level detecting unit 50 is input to the light receiving unit 34 at a minimum if the light emitting unit 14 is alive. When it is smaller than the minimum light receiving level, it is determined that the light emitting unit 14 has deteriorated.

  For example, the user presentation unit 40 displays on the screen of the display unit 44 a GUI (Graphical User Interface) image corresponding to an event related to the internal state of each processing unit input from each processing block. Examples of the event include communication enable / disable information from the optical communication establishment determining unit 60, survival information of the light emitting unit 14 from the light emitting unit death determining unit 80, user input information from the user operation acquiring unit 42, and the like. In addition, the user presenting unit 40 performs management such as updating the GUI displayed on the display unit 44 and controls each processing block. Details of the user presentation unit 40 will be described later.

  The user operation acquisition unit 42 includes input devices such as a remote controller, a keyboard, and a touch panel that include input operation buttons. The user operation acquisition unit 42 generates operation information (event) based on a user input operation and supplies the operation information to the user presentation unit 40. . Further, as will be described later, the user operation acquisition unit 42 performs processing such as limiting input operation buttons that can be operated by the user based on an instruction from the user presentation unit 40.

  The display unit 44 includes a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence). The display unit 44 displays on the screen of the display unit 44 a GUI image (image signal) including characters, images, and the like corresponding to each event supplied from the user presentation unit 40. The display unit 44 can also be configured by a touch panel combined with the user operation acquisition unit 42. Based on the communication availability information supplied from the optical communication establishment determination unit 60, the light shielding / mechanism lock instruction unit 72 performs setting / canceling of the light shielding unit and lock setting / canceling of the substrate holding unit (not shown).

[Another example of block configuration of optical communication system]
The optical communication units 12 and 32 of the optical communication system 100A described above can also be configured by a reflection type. FIG. 2 is a block diagram illustrating a configuration example of the reflective optical communication system 100B. The description of the configuration common to the optical communication system 100A is omitted.

  The light emission control unit 38 includes a light emission unit drive driver and supplies a predetermined operating current to the light emission unit 36. The light emitting unit 36 is composed of, for example, a laser diode or a surface emitting laser, and emits light toward the modulation unit 24 on the functional substrate 10 side by an operating current supplied from the light emission control unit 38. The light receiving unit 34 is configured by, for example, a photodiode, receives an optical signal reflected (output) from the modulation unit 24 on the functional substrate 10 side, converts the optical signal into an electrical signal, and converts the converted electrical signal to an average received light level detection unit 50. Output to.

[Block configuration example of user presentation unit]
FIG. 3 is a block diagram illustrating a configuration example of the user presentation unit 40. The user presentation unit 40 includes an event determination unit 400, a state transition holding unit 401, a user operation setting unit 402, an image generation unit 403, an operation setting unit 404, a GUI data holding unit 405, an image drawing unit 406, and a state acquisition unit 407. Prepare.

  The state transition holding unit 401 is configured by, for example, a non-volatile memory or the like, and has a table (LUT_STATE_TRANS) for managing the state and operation according to the event input to the event determination unit 400. FIG. 4 is a diagram illustrating an example of a data configuration of LUT_STATE_TRANS. In the LUT_STATE_TRANS, the current state S of the user presentation unit 40, the event E input from each processing block, the transition destination state S that transitions according to the event E, and the processing A (program that is performed in the transition destination state ) Are stored in association with each other. Process A constitutes an example of a presentation process.

  The event determination unit 400 receives events E such as communication enable / disable information from the optical communication establishment determination unit 60, survival information from the light emitting unit death determination unit 80, and operation information from the user operation acquisition unit 42. When these events E are input, the event determination unit 400 refers to the LUT_STATE_TRANS of the state transition holding unit 401 and determines the transition destination state S and processing A from the input event E and the current state S. .

  The GUI data holding unit 405 is configured by, for example, a non-volatile memory, and holds images, character data, and the like necessary for generating a GUI image. The image generation unit 403 reads GUI data corresponding to each event E from the GUI data holding unit 405 based on the control information based on the execution of process A from the event determination unit 400, and generates an image signal based on the read GUI data. To the image drawing unit 406. For example, an image signal corresponding to an event E such as communication enable / disable information from the optical communication establishment determination unit 60, survival information such as the light emission unit 14 from the light emission unit death determination unit 80, and operation information from the user operation acquisition unit 42 is generated. To do. The image generation unit 403 performs decompression processing or the like when the GUI data is compressed and stored.

  The image drawing unit 406 generates a drive signal for driving the display device based on the image signal supplied from the image generation unit 403 and supplies the drive signal to the display unit 44. Thereby, a GUI image corresponding to each event E input from each processing block is displayed on the screen of the display unit 44.

  The user operation setting unit 402 supplies operation setting information regarding the operation of the user operation acquisition unit 42 set for each event E supplied from the event determination unit 400 to the user operation acquisition unit 42. The user operation acquisition unit 42 changes the operation method of the GUI image displayed on the display unit 44 for each event E based on the operation setting information supplied from the user operation setting unit 402. For example, as described later, when GUI images of “Yes” and “No” are displayed in the left and right direction of the screen (FIG. 10 and the like), the input operation of the operation buttons other than the left and right direction of the user operation acquisition unit 42 is performed. The user operation acquisition unit 42 is controlled so as to be invalidated. Thereby, an optimal input operation can be realized for each GUI image corresponding to each event E.

  The operation setting unit 404 performs setting corresponding to the event E supplied from the event determination unit 400 for each processing block. For example, in the GUI image displayed on the display unit 44, when the setting of the pixel size for still image acquisition, the setting of the moving image frame rate, the setting of the compression method, the setting of the modulation method is performed, these settings are changed. Perform on processing block. The state acquisition unit 407 acquires various states of each processing block. For example, the remaining amount of the battery for power supply is acquired from a power supply control unit (not shown), and the power state related to the acquired remaining battery level is supplied to the event determination unit 400.

[Operation example of the user presentation unit]
FIG. 5 is a flowchart showing an example of the operation of the user presentation unit 40. In step S10, initialization is performed. For example, the state set at the time of the previous attachment / detachment of the functional board 10 or the power-on of the optical communication system 100A is cleared and returned to the initial state.

  In step S12, input of event E from each processing block is awaited. In step S14, an event E input from each processing block is acquired. In step S16, using the current state S1 and the input event E, the transition destination state S2 and the process A to be executed corresponding to the transition destination state S2 are acquired by referring to LUT_STATE_TRANS.

  In step S18, the own state is changed from the state S1 to the transition destination state S2. In step S20, the process A associated with the transition destination state S2 is performed. For example, predetermined processing is performed on each processing block using the operation setting unit 404, or a GUI image is displayed on the display unit 44 using the image generation unit 403 or the image drawing unit 406.

  In step S22, it is determined whether or not the process A corresponding to the input event is an end process. If it is determined that the process A is an end process, the process ends. If it is determined that the process A is not an end process, the process returns to step S12 to wait for an event input from each process block.

[Events related to communication establishment]
Next, a case where an event related to communication establishment is acquired from the optical communication establishment determination unit 60 will be described. FIG. 6 is a diagram illustrating an example of a configuration of LUT_STATE_TRANS used when an event related to communication establishment occurs. In LUT_STATE_TRANS, an event input from the optical communication establishment determination unit 60, an event generation source, and a process corresponding to the event are stored in association with each other. In FIG. 6, the event of communication establishment or death determination is not limited to a specific state, and it is necessary to always receive an event during operation. Therefore, as shown in FIG. The destination state is not specified.

  For example, when an event “connected device discovery” event is input from the optical communication establishment determining unit 60, the event determining unit 400 receives the LUT_STATE_TRANS No. Referring to 101 ′, the process of “presenting whether to establish communication with the discovered device corresponding to the input event” is performed. In addition, when an event related to communication establishment 'is input from the optical communication establishment determination unit 60, the LUT_STATE_TRANS No. Referring to 102 ′, a process of establishing / not establishing communication establishment corresponding to the input event is performed.

[Operation example when an event related to communication establishment occurs]
Next, the operation of the user presentation unit 40 when an event related to communication establishment is input from the optical communication establishment determination unit 60 will be described. FIG. 7 is a flowchart illustrating an example of the operation of the user presenting unit 40 when an event related to establishment of communication is input from the optical communication establishment determining unit 60. 9 to 15 are diagrams illustrating examples of screens at the time of an event related to communication establishment.

  In step S <b> 30, when the connected device is detected by the optical communication establishment determining unit 60, the event determining unit 400 acquires an event related to the discovery of the connected device from the optical communication establishment determining unit 60. If the optical communication system 100A is a power supply type, the optical communication establishment determination unit 60 determines that the functional substrate 10 is connected to the processing substrate 30 by detecting a level change of the power supply line at the time of connection. An event relating to “discovery of device” is supplied to the event determination unit 400. In addition, since there is a specific partner when determining communication establishment between the functional board 10 and the processing board 30, in this case, it is determined that the functional board 10 is connected to the processing board 30, and an event relating to “discovered connected device” is determined as an event determination unit. 400 may be supplied.

  In addition, the event determination unit 400 reads the process corresponding to this event from the LUT_STATE_TRANS using the event related to “discovered connected device”. Then, a control signal is supplied to the image generation unit 403 so as to generate the GUI image 101-1 corresponding to “presentation whether to establish communication with the discovered device”. The image generation unit 403 reads GUI data corresponding to the GUI image 101-1 from the GUI data holding unit 405, generates an image signal based on the GUI data, and supplies the image signal to the image drawing unit 406.

  In step S32, the image drawing unit 406 displays the GUI image 101-1 (FIG. 10) superimposed on, for example, the initial screen 100-F (FIG. 9). In GUI image 101-1, connection of the device was detected. Do you want to establish communication? Message MS100 and a yes / no selection button BT100 for replying to the message MS100.

  In step S <b> 34, the event determination unit 400 determines whether or not operation information based on “Yes” has been acquired from the user operation acquisition unit 42 in response to the communication establishment message. That is, it is determined whether or not “YES” is selected by the user in the GUI image 101-1 displayed on the display unit 44. If “Yes” is selected, the event determination unit 400 proceeds to step S36 and instructs the optical communication establishment determination unit 60 to detect communication establishment via the operation setting unit 404. On the other hand, if “Yes” is not selected, the process proceeds to step S38.

  In step S <b> 38, the event determination unit 400 determines whether operation information based on “No” has been acquired from the user operation acquisition unit 42. That is, it is determined whether or not “No” is selected by the user on the screen on which the GUI image 101-1 is displayed. If “No” is selected, the event determination unit 400 determines that communication establishment is not performed, and switches to the initial screen 100-F, for example. On the other hand, if “No” is not selected, the process returns to step S34 and waits for a user input.

  In step S <b> 36, when “Yes” is selected, the event determination unit 400 acquires a determination result (communication availability information: event) indicating whether communication is established from the optical communication establishment determination unit 60. If the event determination unit 400 determines in step S38 that the event acquired from the optical communication establishment determination unit 60 is “communication establishment established”, the process proceeds to step S42, and determines that the acquired event is not communication establishment establishment “. If so, the process proceeds to step S44.

  In step S42, when communication is established, the image drawing unit 406 switches the GUI image 101-1 displayed on the display unit 44 to the GUI image 101-2 and displays it (FIG. 11). The GUI image 101-2 includes, for example, a message MS101 indicating that a communication connection to the user has been established, and an OK 'button BT101 for allowing the user to confirm the message MS101. Thereby, the user can grasp that communication has been established between the functional substrate 10 and the processing substrate 30.

  In step S44, the image drawing unit 406 displays the GUI image 101-3 (FIG. 12) on the screen of the display unit 44 when communication is not established. The GUI image 101-3 includes, for example, a message MS102 that a communication connection to the user has not been established, and an OK 'button BT102 for the user to confirm this message MS102. Thereby, the user can grasp that communication is not established between the functional board 10 and the processing board 30.

  In step S <b> 46, when the user selects OK ′ on the screen on which the GUI image 101-3 is displayed, the event determination unit 400 operates the operation information based on “OK” of the GUI image 101-3 from the user operation acquisition unit 42. Is obtained and the process proceeds to step S48 shown in FIG.

  FIG. 8 is a flowchart illustrating an example of the operation of the user presenting unit 40 when communication establishment is not established. In step S <b> 48, the event determination unit 400 determines whether or not survival information (event) indicating that the light emitting unit 14 has died is acquired from the light emitting unit death determining unit 80. The event determination unit 400 proceeds to step S52 when the survival information indicating that the light emitting unit 14 has died is acquired, and proceeds to step S50 when it does not acquire the survival information indicating that the light emitting unit 14 has died.

  In step S52, the event determination unit 400 determines that the light emitting unit 14 has died when the survival information indicating that the light emitting unit 14 has died is acquired, and proceeds to step S54. In step S54, the image drawing unit 406 displays the GUI image 101-4 regarding the death of the light emitting unit 14 on the display unit 44 (FIG. 13). In the GUI image 101-4, for example, the light emitting unit may be broken for the user. Please replace it. Message MS103 and an “OK” button BT103 for the user to confirm this message MS103. Thereby, the user can grasp | ascertain that the light emission part 14 died.

  On the other hand, when determining in step S50 that the light emitting unit 14 is not dead, the event determining unit 400 determines whether or not the received waveform is changed even if the light emitting unit 14 is controlled. For example, the event determining unit 400 increases the reverse voltage applied to the light receiving unit 34 via the operation setting unit 404 and the light emitting unit death determining unit 80, and increases or decreases the amount of light received by the light receiving unit 34 at this time. To detect. If it is determined that there is no change in the received waveform, the process proceeds to step S56. If it is determined that there is a change in the received waveform, the process proceeds to step S60.

  In step S56, if there is no change in the received waveform, the event determination unit 400 determines that the light receiving unit 34 has died and proceeds to step S58. This is because when the reverse voltage applied to the light receiving unit 34 is increased, the amount of received light usually increases and the received waveform also changes. However, when the light receiving unit 34 is dead, the amount of received light changes. This is because the received waveform does not change.

  In step S58, the image drawing unit 406 displays the GUI image 101-5 regarding the death of the light emitting unit 14 on the display unit 44 (FIG. 14). In the GUI image 101-5, for example, the light receiving unit may be broken for the user. Please replace it. Message MS104 and an “OK” button BT104 for the user to confirm this message MS104. Thereby, the user can grasp that the light-receiving part 34 died.

  On the other hand, in step S60, if there is a change in the received waveform, the event determination unit 400 determines that the connection between the functional substrate 10 and the processing substrate 30 is not performed correctly, and proceeds to step S62. For example, it is determined that the optical signal from the light emitting unit 14 is not correctly received by the light receiving unit 34 due to the displacement of the connection of the functional board 10.

FIG. 16 is a functional block diagram showing a configuration example of an optical communication system 100C according to the second embodiment of the present invention. The optical communication system 100 </ b> C includes a functional substrate 10 having an optical communication unit 12 and a processing substrate 30. The optical communication unit 12 includes a light emitting unit 14, an optical transmission control unit 16, and a functional unit operation start instruction unit 18. The light transmission control unit 16 drives the light emitting unit 14 based on the power parameter α set by the light drive instruction unit 58 described later.

  The processing substrate 30 includes an optical communication unit 32, an optical communication establishment determination unit 60, an optical reception control unit 54, a light emission unit death determination unit 80, a user presentation unit 40, a user operation acquisition unit 42, a display unit 44, a light shielding and mechanism lock instruction. Part 72. Further, the processing substrate 30 includes an error rate detection unit 52, a light drive instruction unit 58, a transfer rate setting unit 56, and a positional deviation determination unit 74. The optical communication unit 32 includes a light receiving unit 34 and an average light reception level detecting unit 50.

  The transfer rate setting unit 56 acquires the imaging mode selected by the user from the user presenting unit 40, and sets the acquired transfer rate for each imaging mode in the light driving instruction unit 58. The imaging mode is a driving mode of an image sensor (pixel unit) (not shown), and examples thereof include an all-pixel reading mode, a draft mode, a 2 × 2 pixel addition mode, and the like. The transfer rate is the speed of data communication between the functional board 10 and the processing board 30 and is set for each imaging mode described above in this example.

  The light drive instructing unit 58 adjusts the power parameter α for driving the light emitting unit 14 and the light receiving sensitivity of the light receiving unit 34 that satisfy the reference error rate to be realized for each transfer rate supplied from the transfer rate setting unit 56. The sensitivity parameter r for performing the above is acquired (generated). For example, the sensitivity parameter r is set to a value that satisfies a predetermined reference error rate and minimizes the power consumption (power parameter α) of the light emitting unit 14. The optical drive instruction unit 58 sets the acquired power parameter α in the optical transmission control unit 16 and sets the sensitivity parameter r in the optical reception control unit 54 and the error rate detection unit 52. In addition, the light drive instruction unit 58 has a lookup table that stores the selected value of the error rate, the optimum power parameter α, and the sensitivity parameter r in association with each other.

  The light reception control unit 54 adjusts the light receiving sensitivity of the light receiving unit 34 based on the sensitivity parameter r supplied from the light driving instruction unit 58. For example, a predetermined reverse voltage is applied to the light receiving unit 34 as the sensitivity parameter r.

  The light receiving unit 34 includes, for example, an APD (avalanche photodiode) or PIN-PD as a light receiving element, and converts an optical signal output from the light emitting unit 14 into an electrical signal to obtain an image signal or a test pattern. The test pattern converted into the electric signal is supplied to the error rate detection unit 52. The light receiving unit 34 adjusts the detection voltage amount of the received optical signal by the sensitivity parameter r (reverse voltage) supplied from the light reception control unit 54.

  The error rate detection unit 52 performs bit determination of the test pattern supplied from the light receiving unit 34 based on the sensitivity parameter r set by the light drive instruction unit 58, and calculates an error rate. The calculated error rate is supplied to the light drive instruction unit 58, and it is determined whether or not the reference error rate is satisfied.

  The positional deviation determination unit 74 determines the positional deviation (optical axis deviation) between the functional substrate 10 and the processing substrate 30 from the average light reception level acquired from the average light reception level detection unit 50. If it is determined that there is a displacement, for example, the displacement information (event) is supplied to the event determination unit 400 of the user presentation unit 40. As a determination method of the positional deviation, for example, the amount of change in the average light reception level at time t and time t−1 is acquired, and when the average light reception level is stable in a lowered state, it is determined that the positional deviation has occurred. .

  FIG. 17 is a diagram illustrating an example of a data configuration of LUT_STATE_TRANS held by the state transition holding unit 401 of the user presenting unit 40. In LUT_STATE_TRANS, an event input from the light emitting unit death determining unit 80, the positional deviation determining unit 74, and the optical communication establishment determining unit 60, an event generation source, and a process corresponding to the event are stored in association with each other.

Message MS220 and a 'Yes / No' button BT220 for responding to this message MS220.

  In step S <b> 84, the event determination unit 400 determines whether operation information (event) based on “Yes” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “Yes” in the GUI image 002-2-1 is selected by the user. If the event determination unit 400 determines that the operation information based on “Yes” has been acquired, the process proceeds to step S86. If the event determination unit 400 determines that the operation information based on “Yes” has not been acquired, the process proceeds to step S88.

  In step S <b> 88, the event determination unit 400 determines whether operation information (event) based on “No” has been acquired from the user operation acquisition unit 42. That is, it is determined whether or not “No” in the GUI image 002-2-1 displayed on the display unit 44 is selected by the user. If the event determination unit 400 determines that the operation information based on “No” has been acquired, for example, the event determination unit 400 transitions to an initial state and ends the series of operations. On the other hand, if it is determined that the operation information based on “No” has not been acquired, the process returns to step S84 to wait for a user input.

(Modulation method change)
In the above-described example, the error rate setting is changed to cope with the deterioration of the light emitting unit 14. Instead, the pixel data modulation method can be changed to cope with the deterioration of the light emitting unit 14. Is possible. FIGS. 32A and 33B are diagrams illustrating an example of the screen of the display unit 44 when the modulation method is changed. Note that description of the configuration and operation common to the case of resetting the error rate is omitted.

  When the deterioration determination process by the event determination unit 400 is executed, the image drawing unit 406 displays a GUI image 002-3 regarding deterioration of the light emitting unit 14 on the draft mode screen 100-A displayed on the display unit 44. -1 is superimposed and displayed (FIG. 32A).

Message 241 ', a modulation level that can be selected by the user' button BT 241, and a “decision” button BT 242 for confirming the selected modulation level.

  In this example, for example, three modulation levels 1 to 3 having different error correction capabilities are prepared, and the error correction capability increases as the modulation level increases. As a method of increasing the error correction capability, for example, a method of increasing the error correction code length can be mentioned. Accordingly, when the message MS240 of “deterioration of the light emitting unit 14” is displayed, the error correction capability is improved by selecting the one with a high modulation level via the user operation acquisition unit 42. It can cope with deterioration.

(Change compression method)
Further, the deterioration of the light emitting unit 14 can be dealt with by changing the compression rate of the pixel data instead of changing the setting of the error rate. FIG. 33A and FIG. 33B are diagrams showing an example of the screen of the display unit 44 when the compression method is changed. Note that description of the configuration and operation common to the case of resetting the error rate is omitted.

Message MS251, “compression level selectable by the user” button BT251, and a “decision” button BT252 for confirming the selected compression level.

  In this example, for example, three compression levels 1 to 3 having different compression levels are prepared. As the compression level increases, the image quality deteriorates, but the data size decreases and the data rate can be lowered. Therefore, when the deterioration of the light emitting unit 14 is detected, it is possible to increase the error correction capability and cope with the deterioration of the light emitting unit 14 by selecting a large compression level via the user operation acquisition unit 42. In the above description, the modulation method and the compression method are described separately. However, a combination of these may be selected so that both the modulation level and the compression level can be selected.

(Modification)
Further, as described above, the user does not select the modulation level or compression level, but the user presentation unit 40 determines the appropriate modulation level and compression level according to the deterioration of the light emitting unit 14 and automatically You may make it change a modulation level and a compression level. FIG. 34A and FIG. 34B are diagrams illustrating an example of a screen when the modulation level and the compression level are automatically changed.

The GUI image 004-1 no longer establishes communication with connected devices for the user. Do you want to diagnose the failure? Message MS240 and a 'Yes / No' button BT240 for responding to this message MS240.

  In step S134, the event determination unit 400 determines whether or not the operation information (event) based on “Yes” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “Yes” in the GUI image 004-1 is selected by the user. If the event determination unit 400 determines that the operation information based on “Yes” has been acquired, the process proceeds to step S136. The light emitting unit death determining unit 80 determines whether or not the light emitting unit 14 has died. On the other hand, if it is determined that the operation information based on 'Yes' has not been acquired, the process proceeds to step S138.

  In step S <b> 138, the event determination unit 400 determines whether operation information based on “No” has been acquired from the user operation acquisition unit 42. That is, it is determined whether or not “No” in the GUI image 004-1 displayed on the display unit 44 is selected by the user. If the event determination unit 400 determines that the operation information based on “No” has been acquired, for example, the event determination unit 400 transitions to an initial state and ends the series of operations. On the other hand, if it is determined that the operation information based on “No” has not been acquired, the process returns to step S134 to wait for user input.

  On the other hand, in step S <b> 136, the event determination unit 400 determines whether or not survival information (event) indicating that the light emitting unit 14 has died is acquired from the light emitting unit death determining unit 80. If the event determination unit 400 acquires the survival information indicating that the light emitting unit 14 has died, the event determination unit 400 proceeds to step S142. On the other hand, if it is determined that the survival information indicating that the light emitting unit 14 has not been acquired has been acquired, the process proceeds to step S140.

  In step S <b> 142, the event determination unit 400 determines that the light emitting unit 14 has died when acquiring the survival information that the light emitting unit 14 has died from the light emitting unit death determining unit 80. Then, referring to LUT_STATE_TRANS, a process of “presenting death and presenting replacement corresponding to the death” event of the light emitting unit is executed.

  In step S144, the image drawing unit 406 switches the GUI image 004-1 displayed on the display unit 44 to the GUI image 004-2 (FIG. 44) regarding the death of the light emitting unit and displays it. In the GUI image 004-4, for example, the light emitting unit for the user may be broken. Please replace it. Message MS241 and an “OK” button BT241 for selecting when the message MS241 is confirmed. By this display, the user can confirm that the light emitting unit 14 is out of order and needs to be replaced.

  On the other hand, in step S140, the event determination unit 400 determines whether or not an event indicating that the connected device has been displaced has been acquired from the displacement determination unit 74, for example. If the event determination unit 400 determines that a position shift event has been acquired from the position shift determination unit 74, the process proceeds to step S148. On the other hand, if it is determined that the position shift event information has not been acquired from the position shift determination unit 74, the process proceeds to step S146.

  In step S <b> 148, when the event determination unit 400 acquires a position shift event from the position shift determination unit 74, the event determination unit 400 determines that the connected device is not correctly connected. Then, the event determination unit 400 refers to the LUT_STATE_TRANS and executes the “presentation of misalignment correction method corresponding to the misalignment event” process.

  In step S150, the image drawing unit 406 switches the GUI image 004-1 displayed on the display unit 44 to the GUI image 004-3 (FIG. 45) related to the positional deviation presentation. For example, the GUI image 004-3 may not be correctly connected to the user. Check the connection status. Message MS242 and an “OK” button BT242 for selecting when the message MS242 is confirmed. With this display, the user can confirm that the connected device is not normally connected and it is necessary to check the connection state.

  On the other hand, in step S146, the event determination unit 400 changes to a reception waveform even if the reverse voltage applied to the light receiving unit 34 is controlled when the light emitting unit 14 is alive and the displacement of the connected device is not detected. It is determined whether or not there is any. For example, the event determination unit 400 increases the reverse voltage applied to the light receiving unit 34 via the light emitting unit death determination unit 80 and detects an increase or decrease in the amount of light received by the light receiving unit 34 at this time. Event determining section 400 proceeds to step S154 when determining that there is no change in the received waveform, and proceeds to step S152 when determining that there is a change in the received waveform.

  In step S154, if there is no change in the received waveform, the event determination unit 400 determines that the light receiving unit 34 has died and proceeds to step S156. This is because when the reverse voltage applied to the light receiving unit 34 is increased, the light receiving sensitivity of the light receiving unit 34 usually increases, so the amount of received light increases and the received waveform also changes, but the light receiving unit 34 is dead. This is because the received light waveform does not change because the amount of received light does not change.

  In step S <b> 156, the image drawing unit 406 switches the GUI image 004-1 displayed on the display unit 44 to a GUI image 004-4 (FIG. 46) that prompts replacement of the light receiving unit 34 and displays it. In the GUI image 004-4, the light receiving unit for the user may be broken. Please replace it. Message MS243 and an OK 'button BT243 selected when the message MS243 is confirmed. By this display, the user can grasp that there is a possibility that the light receiving unit is out of order.

  On the other hand, in step S152, the event determination unit 400 determines that there is an obstacle such as a foreign object (garbage) in the path between the optical communication units 12 and 32 when no change in the received waveform of the light receiving unit 34 is detected. . Then, with reference to LUT_STATE_TRANS, processing corresponding to the event relating to “connection failure due to obstacle” is executed.

  In step S <b> 158, the image drawing unit 406 switches the GUI image 004-1 displayed on the display unit 44 to the GUI image 004-3 (FIG. 45) related to poor connection and displays it. By this display, the user can grasp that there is some connection failure between the connected device and the processing board 30. As described above, when the establishment of communication is not established, accurate information corresponding to these events is obtained by diagnosing the internal state of the light emitting unit 14 and the light receiving unit 34 in the optical communication system 100A such as deterioration and death in detail. Can be presented to the user.

  As described above, according to the present embodiment, the same operational effects as those of the first embodiment can be obtained. In other words, in the present embodiment, whether the light emitting unit 14 on the functional substrate 10 side is deteriorated, the light receiving unit 34 on the processing substrate 30 side is dead, or whether there is a displacement in accordance with each event that occurs. A more detailed internal state of the optical communication system 100C is presented. Thereby, the user can grasp | ascertain the internal state of 100 C of optical communication systems more correctly. As a result, the possibility of destruction or failure of the optical communication system 100C can be reduced.

<3. Third Embodiment>
[Block configuration example of optical communication system]
The third embodiment of the present invention will be described below with reference to the drawings. In the third embodiment, information presentation to the user when a heat generation event occurs will be described. In addition, the same code | symbol is attached | subjected to the component which is common in optical communication system 100A-100C of 1st and 2nd embodiment mentioned above, and detailed description is abbreviate | omitted.

  FIG. 47 is a functional block diagram showing a configuration example of an optical communication system 100D according to the third embodiment of the present invention. The optical communication system 100D includes a solid-state imaging device 10A and a processing substrate 30. The solid-state imaging device 10 </ b> A includes a pixel unit 11, an optical communication unit 12, an average light emission level detection unit 20, a cooling unit 26, and a cooling control unit 28.

  The pixel unit 11 includes, for example, a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor. The pixel unit 11 converts imaging light incident through a lens (not shown) or the like into an electrical signal for each pixel, and generates an image signal. The image signal is gain-adjusted by, for example, an amplification unit, and noise is removed by a CDS (Correlated Double Sampling circuit). The gain-adjusted analog image signal is converted into a digital image signal by the A / D converter and supplied to the optical communication unit 12.

  The optical communication unit 12 includes, for example, a laser diode (LD) or a surface emitting semiconductor laser array (VCSEL). For example, when a modulation current corresponding to an image signal and a drive current are supplied from a control unit (not shown), the optical communication unit 12 converts the pixel signal into an optical signal and outputs (emits) light.

  The average light emission level detection unit 20 detects the optical signal output from the optical communication unit 12, and calculates the average light emission level of the optical signal based on the light emission level (light quantity) of the detected optical signal. The average light emission level detection unit 20 supplies the calculated average light emission level to the optical communication unit heat generation determination unit 70 on the processing substrate 30 side.

  The cooling control unit 28 drives the cooling unit 26 based on the cooling drive value supplied from the heat generation suppression instruction unit 78. The cooling unit 26 includes, for example, a Peltier element or a fan, and cools each processing block such as the optical communication unit 12 or the pixel unit 11 that is a cooling target based on the cooling drive value from the cooling control unit 28. .

  The processing substrate 30 includes an optical communication unit 32, a user presentation unit 40, a user operation acquisition unit 42, a display unit 44, an optical communication unit heat generation determination unit 70, a heat generation suppression instruction unit 78, a cooling unit 90, a cooling control unit 92, and power control. Part 37. The optical communication unit 32 includes, for example, a photodiode (PD), receives the optical signal output from the optical communication unit 32, and converts it into an electrical signal.

  The optical communication unit heat generation determination unit 70 is an example of a processing unit, and determines whether or not the optical communication unit 12 is generating heat based on the average light emission level supplied from the average light emission level detection unit 20 on the solid-state imaging device 10A side. to decide. As a method for determining heat generation, for example, an average light emission level supplied from the average light emission level detection unit 20 on the solid-state imaging device 10A side is compared with a preset light emission level during heat generation, and the average light emission level is higher than the light emission level during heat generation. Is smaller, it is determined that the optical communication unit 12 is generating heat. As another method, when the average light emission level per unit time supplied from the average light emission level detection unit 20 of the solid-state imaging device 10A tends to decrease, it is determined that the optical communication unit 12 is generating heat. You can also.

  When the optical communication unit heat generation determination unit 70 determines that the optical communication unit 12 generates heat, the heat generation suppression instruction unit 78 instructs the cooling control units 28 and 92 to cool the object to be cooled. The heat generation suppression instruction unit 78 holds a cooling drive value for driving the cooling units 26 and 90. The cooling drive value includes, for example, a cooling drive voltage applied to the cooling control units 28 and 92, a cooling time, a cooling range, and the like.

  The power control unit 37 performs, for example, power management on the processing substrate 30 side, and supplies power to the optical communication unit 32 and the like. The power control unit 37 may perform power management on the solid-state imaging device 10A side. In addition, the power control unit 37 detects the remaining amount of a battery or the like serving as a power supply source, and supplies the detected detection information (event) to the event determination unit 400 of the user presentation unit 40.

  FIG. 48 is a diagram illustrating an example of a data configuration of LUT_STATE_TRANS held by the state transition holding unit 401 of the user presenting unit 40. In LUT_STATE_TRANS, an event input from the optical communication unit heat generation determination unit 70, an event generation source, and a process corresponding to the event are stored in association with each other. For example, when an event related to heat generation is input from the optical communication unit heat generation determination unit 70 ′, the event determination unit 400 refers to LUT_STATE_TRANS and determines according to the remaining power level of the power source 1. Cooling, 2. 2. Restriction of operation. Perform processing such as 'Power off'.

[Operation example of the user presentation unit]
FIG. 49 is a flowchart illustrating an example of the operation of the user presentation unit 40 at the time of a heat generation event. 50 to 54 are diagrams illustrating examples of GUI images displayed on the screen of the display unit 44 when a heat generation event is input. FIG. 55A to FIG. 55C are diagrams showing an example of the state of the remaining battery level.

  In step S <b> 200, when the optical communication unit heat generation determination unit 70 detects the heat generation of the optical communication unit 12, the event determination unit 400 acquires an event related to the temperature increase of the optical communication unit 12 from the optical communication unit heat generation determination unit 70. This is because when the optical communication unit 12 generates heat due to deterioration or the like, the operating current also increases. Therefore, when the temperature of the optical communication unit 12 rises and the remaining battery level is low, This is because it is necessary to reduce consumption.

  In step S <b> 202, the event determination unit 400 acquires an event related to the remaining battery level Bv from the power supply control unit 37. As shown in FIG. 55 (A), the remaining battery level Bv is, for example, less than the remaining battery level B_1 and is in a state of hardly remaining.

  In step S204, the event determination unit 400 determines whether or not the remaining battery level Bv acquired from the power control unit 37 is equal to or lower than the remaining battery level B_1. When it is determined that the remaining battery level Bv is equal to or lower than the remaining battery level B_1, the process proceeds to step S208, and when it is determined that the remaining battery level Bv exceeds the remaining battery level B_1, the process proceeds to step S206.

  In step S208, the image drawing unit 406 switches and displays the draft mode screen 100-A (FIG. 50) displayed on the display unit 44 to the GUI image 101-3 (FIG. 51) relating to power-off. In the GUI image 101-3, for example, the temperature inside the device for the user is rising. Turn off the power and use it after a while. Message MS300 and an “OK” button BT300 for selecting when the message MS300 is confirmed. The reason for turning off the power is that when the remaining battery level Bv is low, power is consumed due to heat generation, and the system may be forcibly terminated, for example.

  In step S210, when the OK ′ button BT300 of the GUI image 101-3 is selected, the event determination unit 400 acquires operation information (event) based on OK ′ from the user operation acquisition unit. And it changes to an initial state, for example, switches to the initial screen 100-F, and displays.

  On the other hand, in step S206, the event determination unit 400 determines whether or not the remaining battery level Bv acquired from the power control unit 37 is equal to or lower than the remaining battery level B_2. As shown in FIG. 55B, for example, the remaining battery level Bv is higher than the remaining battery level B_1 and lower than B_2, and the remaining battery level is low. When it is determined that the remaining battery level Bv is equal to or lower than the remaining battery level B_2, the process proceeds to step S214, and when it is determined that the remaining battery level Bv exceeds the remaining battery level B_2, the process proceeds to step S212.

  In step S214, the image drawing unit 406 switches from the GUI image 101-3 displayed on the display unit 44 to the GUI image 101-4 (FIG. 52) relating to the limitation of the operation mode and displays it. In the GUI image 101-4, for example, the temperature of the optical communication unit in the device for the user is rising. Restricts the operation mode. Message MS301 and an “OK” button BT301 for selecting when the message MS301 is confirmed. In this case, since a certain amount of remaining battery power is secured, the system can be operated continuously by restricting the operation mode.

  In step S <b> 216, when the OK ′ button BT <b> 301 of the GUI image 101-4 is selected, the event determination unit 400 acquires operation information (event) based on OK ′ from the user operation acquisition unit 42. Then, the GUI image 101-4 on the display unit 44 is switched to and displayed on the operation setting screens 101-A and B (FIG. 54) for restricting the operation mode.

  In step S218, the user operation setting unit 402 constrains the options on the shooting setting screen 101-A. FIG. 54A shows a shooting setting screen 101-A before heat generation, and FIG. 54B shows a shooting setting screen 101-B after heat generation. Before the generation of heat, it is possible to select all items of the number of pixels in the still image mode and all items of the number of moving image pixels in the moving image mode. On the other hand, after heat generation, the operation setting of the user operation acquisition unit 42 is changed so that the user cannot select the processing / operation with large heat generation, that is, the items P1 and P2 (dotted lines) having a large number of pixels. To do. For the items P1 and P2 of the number of pixels that cannot be selected, the display on the screen is highlighted, for example, or grayed-out so that the user can recognize that the item is not visually selectable.

  On the other hand, in step S212, the image drawing unit 406 displays the draft mode screen 100-A displayed on the display unit 44 when the remaining battery level Bv is equal to or higher than the remaining battery level B_2 (see FIG. 55C). Is switched to the GUI image 101-5 (FIG. 53) regarding cooling. In the GUI image 101-5, for example, the temperature of the optical communication unit in the device for the user is rising. Do you want to cool down? Message MS302 and an “OK” button BT302 for selecting when the message MS302 is confirmed. In this case, since the remaining battery charge Bv is sufficient, it is possible to cope with the cooling process of the heat source without turning off the power or limiting the operation mode.

  In step S <b> 220, the event determination unit 400 determines whether or not operation information (event) based on “Yes” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “YES” in the GUI image 101-5 is selected. If it is determined that the operation information based on “Yes” has been acquired, the process proceeds to step S222. If it is determined that the operation information based on “Yes” has not been acquired, for example, a transition is made to the initial state. In step S <b> 222, the event determination unit 400 causes the cooling units 26 and 90 to cool the object to be cooled via the operation setting unit 404.

  As described above, according to the present embodiment, the same operational effects as those of the first embodiment can be obtained. That is, in the present embodiment, information corresponding to the heat generation event is presented to the user, so that the user can more accurately grasp the internal state of the optical communication system 100D. As a result, it is possible to respond quickly and accurately, and the possibility of destruction or failure of the optical communication system 100D can be reduced.

[Modification 1]
The temperature state of the light emitting unit 14 detected by the optical communication unit heat generation determination unit 70 can also be presented to the user by an indicator. 56 (A) and 56 (B) are diagrams illustrating an example in which the temperature state of the light emitting unit 14 detected by the optical communication unit heat generation determination unit 70 is displayed on the display unit 44 by an indicator.

  In response to the heat generation event, the user presentation unit 40 displays, for example, a GUI image 002-6 including an icon IC 270 indicating heat and a bar ING 270 indicating the temperature state of the light emitting unit 14 at the lower right of the draft mode screen. 1 is displayed (FIG. 56A). Then, when the temperature of the light emitting unit 14 exceeds a predetermined threshold temperature, the GUI image 002-6-2 (configured with a message MS271 indicating that the temperature of the light emitting unit 14 has risen and cooling is required. 56 (B)) is displayed in a pop-up, and the necessity for cooling is presented to the user. In addition, the information presentation method using this indicator is not limited to a heat generation event, but can also be applied when an event such as a deterioration state of the light emitting unit 14 or a state of external light occurs.

[Modification 2]
Next, a case will be described in which the user presenting unit 40 determines and processes an event by itself instead of asking the user to select a process at the time of a heat generation event. FIG. 57 is a flowchart illustrating an example of control of the user presentation unit 40 when a heat generation event occurs. 58 (A) to 58 (C) are diagrams illustrating an example of a screen at the time of a heat generation event.

  In step S320, the event determination unit 400 acquires the temperature increase event of the optical communication unit 12 from the optical communication unit heat generation determination unit 70. In step S322, when the temperature increase event of the optical communication unit 12 is acquired, the image drawing unit 406 displays the temperature increase of the optical communication unit 12 on the draft mode screen 100-A displayed on the display unit 44. The image 201-1 is superimposed and displayed (FIGS. 58A and 58B). In the GUI image 201-1, the temperature inside the device for the user is rising. Message MS320.

  In step S324, the event determination unit 400 determines whether the display time of the GUI image 201-1 has elapsed for a predetermined time. The display time is set to a time sufficient for the user to confirm the content of the message, for example. If the event determination unit 400 determines that the display time of the GUI image 201-1 has elapsed, the process proceeds to step S326.

  In step S326, when the event determination unit 400 displays the GUI image 201-1 for a certain period of time, it is assumed that the user has recognized that the temperature of the optical communication unit 12 in the device is rising, and the GUI image 201-1 is displayed. Is erased (FIG. 58 (C)). Then, the subsequent processing is left to the user himself. In this way, the user presentation unit 40 automatically determines the temperature rise in the device, and controls display / non-display of the GUI image 201-1 according to the event.

<4. Fourth Embodiment>
The fourth embodiment of the present invention will be described below with reference to the drawings. The fourth embodiment is different from the first to third embodiments in that the user is shielded from light according to the light shielding event from the external light detection unit 76. In addition, the same code | symbol is attached | subjected to the component which is common in optical communication system 100A-100D which concerns on the 1st-3rd embodiment mentioned above, and detailed description is abbreviate | omitted.

[Block configuration example of optical communication system]
FIG. 59 is a functional block diagram showing a configuration example of an optical communication system 100E according to the fourth embodiment of the present invention. The optical communication system 100E includes a functional substrate 10 and a processing substrate 30. The functional board 10 has an optical communication unit 12. The optical communication unit 12 includes a light emitting unit 14, an optical transmission control unit 16, and a functional unit operation start instruction unit 18.

  The processing board 30 includes an optical communication unit 32, a light emitting unit death determination unit 80, a user presentation unit 40, a user operation acquisition unit 42, a display unit 44, an external light detection unit 76 which is an example of a processing unit, a light shielding and mechanism lock instruction unit. 72. The optical communication unit 32 includes a light receiving unit 34, an average light reception level detecting unit 50, and an optical communication establishment determining unit 60.

  The external light detection unit 76 includes, for example, a photodiode, and has a high light reception sensitivity with respect to external light and a low light reception sensitivity or no light reception sensitivity with respect to communication light emitted from the light emitting unit 14. . The external light detection unit 76 detects external light incident on the processing substrate 30 (for example, in the vicinity of the light receiving unit 34 of the optical communication unit 32), and calculates the external light state (external light intensity) based on the detected external light. And supplied to the user presentation unit 40.

  The user presentation unit 40 includes an external light table in which the external light intensity from the external light detection unit 76 is associated with a threshold value for determining whether or not light is blocked. This external light table may be held in the state transition holding unit 401. The user presenting unit 40 determines the presence or absence of light blocking by referring to the table for external light using the external light intensity (event) supplied from the external light detection unit 76. If a light shielding event occurs as a result of this determination, the light shielding / mechanism lock instruction unit 72 is instructed to perform light shielding processing. The light shielding / mechanism lock instruction unit 72 executes a light shielding process based on an instruction from the user presenting unit 40.

  FIG. 60 is a diagram illustrating an example of a data configuration of LUT_STATE_TRANS held in the state transition holding unit 401 of the user presenting unit 40. In LUT_STATE_TRANS, an event input from the external light detection unit 76, an event generation source, and a process corresponding to the event are stored in association with each other. For example, when an event related to light shielding is input from the outside light detection unit 76 ′, the event determination unit 400 executes a process of “prompt light shielding with reference to LUT_STATE_TRANS”.

[Operation example of the user presentation unit]
FIG. 61 is a flowchart illustrating an example of the operation of the user presentation unit 40 when an event related to light shielding is input. 62 to 64 are diagrams illustrating an example of a GUI image displayed on the display unit 44 when an event related to light shielding is input.

  In step S <b> 160, when the ambient light is detected by the ambient light detection unit 76, the event determination unit 400 acquires the ambient light intensity (event) from the ambient light detection unit 76. At this time, as shown in FIG. 63, a GUI image 202-1 including an indicator of the acquired external light intensity may be displayed on the draft mode screen 100-A. In this case, for example, the external light intensity is displayed stepwise by “weak, medium, strong” and “1, 2, 3, 4, 5”, so that the user is always aware of the external light intensity. Of course, the normal draft mode screen 100-A may be used (FIG. 62).

  In step S162, the event determination unit 400 determines whether or not the acquired external light intensity is greater than or equal to a predetermined threshold value. For example, the event determination unit 400 refers to the external light table held in the state transition holding unit 401 and determines whether or not the acquired external light intensity is equal to or greater than a predetermined threshold. If the event determination unit 400 determines that the external light intensity is greater than or equal to a predetermined threshold value, the event determination unit 400 executes a process of “prompt light blocking corresponding to an event related to light blocking” as the light blocking process is necessary, and proceeds to step S164. On the other hand, when it is determined that the external light intensity is less than the predetermined threshold value, the external light intensity from the external light detection unit 76 is continuously acquired, and whether or not the acquired external light intensity is equal to or greater than the predetermined threshold value. Determine whether.

  In step S164, the image drawing unit 406 switches and displays the screen of the display unit 44 to the GUI image 202-2 (FIG. 64) that prompts the user to block light based on the “prompt to block light” process. The GUI image 202-2 seems to have strong external light for the user, for example. Shading is necessary for proper operation. Do you do shading? Message MS400 and a yes / no button BT400 for replying to the message MS400.

  In step S166, the event determination unit 400 determines whether or not the operation information (event) based on “Yes” is acquired from the user operation acquisition unit. That is, it is determined whether or not the “Yes” button BT400 of the GUI image 202-2 is selected. If the event determination unit 400 determines that the operation information (event) based on “Yes” is acquired from the user operation acquisition unit 42, the process proceeds to step S168. On the other hand, if it is determined that the operation information (event) based on “Yes” is not acquired from the user operation acquisition unit 42, for example, the series of operations is terminated without performing the light shielding process.

  In step S 168, when the event determination unit 400 acquires the operation information (event) based on “Yes” from the user operation acquisition unit 42, the event determination unit 400 performs the light blocking process on the light blocking and mechanism lock instruction unit 72 via the operation setting unit 404. To instruct.

  As described above, according to the present embodiment, the same operational effects as those of the first embodiment can be obtained. That is, in the present embodiment, information corresponding to the light shielding event is presented to the user, so that the user can more accurately grasp the internal state of the optical communication system 100E. As a result, it is possible to respond quickly and accurately, and the possibility of destruction or failure of the optical communication system 100E can be reduced.

[Modification]
Next, a description will be given of a case where the user presentation unit 40 determines and processes an event by itself, instead of asking the user to select a process when presenting a shading event. FIG. 65 is a flowchart showing an example of the operation of the user presentation unit 40 at the time of a light shielding event. 66A and 66B are diagrams illustrating an example of a screen at the time of a light shielding event.

  In step S <b> 300, the event determination unit 400 acquires an event related to external light intensity ′ from the external light detection unit 76. The external light detection unit 76 detects external light intensity based on external light incident on the optical communication system 100 </ b> A at regular intervals or at regular intervals, and supplies the detected external light intensity to the event determination unit 400.

  In step S <b> 302, the event determination unit 400 determines whether the external light intensity acquired from the external light detection unit 76 is greater than or equal to a predetermined threshold value. The threshold is set to a value that does not affect the communication light used for communication between the light emitting unit 14 and the light receiving unit 34, for example. If the event determination unit 400 determines that the external light intensity acquired from the external light detection unit 76 is equal to or greater than the predetermined threshold value, the event determination unit 400 determines that the light shielding process is necessary and proceeds to step S304. On the other hand, when determining that the external light intensity acquired from the external light detection unit 76 is less than the predetermined threshold, the event determination unit 400 determines that the light shielding process is not necessary.

  In step S304, the image drawing unit 406 superimposes and displays the GUI image 203 indicating that the shading process has been performed on the draft mode screen displayed on the display unit 44 (FIG. 66A). The GUI image 203 is shielded because it has strong external light to the user. Message MS410.

  In step S <b> 306, the event determination unit instructs the light shielding / mechanism lock instruction unit 72 to execute the light shielding process together with the display of the GUI image 203 via the operation setting unit 404. The light shielding / mechanism lock instructing unit 72 executes a light shielding process based on an instruction from the operation setting unit 404, and suppresses external light incident on the optical communication system to a constant external light intensity.

  In step S308, the event determination unit 400 determines whether or not the display time of the GUI image 203 has elapsed for a predetermined time. For example, the display time is set to a time during which the user can sufficiently confirm the content of the message MS410. If the event determination unit 400 determines that the display time of the GUI image 203 has elapsed for a predetermined time, the event determination unit 400 proceeds to step S310. If the event determination unit 400 determines that the predetermined time has not elapsed, the event determination unit 400 proceeds to the GUI image 203. Is displayed continuously.

  In step S310, the event determination unit 400 displays the GUI image 203 for a certain period of time and turns off the display of the GUI image 203 on the assumption that the user has recognized that the shading process has been performed (FIG. 66B). In this way, the user presentation unit 40 automatically determines a temperature rise in the device, and controls display / non-display of the GUI image 203 according to the event.

<5. Fifth embodiment>
Next, a fifth embodiment of the present invention will be described with reference to the drawings. The fifth embodiment is different from the first to fourth embodiments in that information is presented to the user in accordance with an event generated by the user's input operation. In addition, the same code | symbol is attached | subjected to the component which is common in optical communication system 100A-100E which concerns on the 1st-4th embodiment mentioned above, and detailed description is abbreviate | omitted.

[Example of state transition of user presentation unit]
FIG. 67 is a state transition diagram of the user presentation unit 40 when, for example, the optical communication system 100A is turned on, a menu screen is displayed on the display unit 44, and various operations are performed from the displayed menu screen. First, when the power of the optical communication system 100A is turned on by the user, the state transitions to the initial state, and then transitions to the state 100 to display the menu screen. When a device connection event is input by the user in the state 100, the state transitions to the state 110 to display connectable devices.

  On the other hand, when the device removal event is input by the user in the state 100, the state transitions to the state 160 to display the connected device. In the state 160, when there are a plurality of connection device removal procedures, the connection device removal procedure is repeatedly displayed a plurality of times. Then, when a connection device removal completion event is input by the user, a transition is made to the initial state.

  When a connection event with the device A is input by the user in the state 110, the state changes to the state 110_A and the connection procedure of the device A is displayed. Similarly, when a connection event with the device B is input in the state 110, the state changes to the state 110_B and the connection procedure of the device B is displayed.

  When a connection confirmation event is input by the user in the state 110_A, the state transitions to the state 120. On the other hand, in the state 110_A, when an event that does not confirm the connection is input by the user, the state transits to the state 130 and enters a standby state. Similarly, when a connection confirmation event is input by the user in state 110_B, the state transitions to state 120. On the other hand, in the state 110_B, when an event that does not confirm the connection is input by the user, the state transits to the state 130 and enters a standby state.

  When a communication establishment establishment event is input in the state 120, the state transitions to the state 140. In the state 140, the normal operation (menu operation system) of the application is performed. On the other hand, when a communication establishment failure event is input in the state 120, the state transitions to the state 150. In the state 150, connection re-procedure or failure diagnosis is presented.

[Operation example of the user presentation unit]
Next, the operation of the user presentation unit 40 when an event is input according to a user operation will be described in detail. 68 to 76 are flowcharts showing an example of the operation of the user presentation unit 40 when an event is input according to a user operation. 77 to 98 are diagrams illustrating an example of a GUI image displayed on the display unit 44 when an event corresponding to a user operation is input.

(Device connection event)
First, a device connection event will be described. In step S500 shown in FIG. 68, when the user turns on the power, the event determination unit 400 acquires an event related to the menu screen display. An initial screen 100-F (FIG. 77) is displayed on the screen of the display unit 44. The event relating to the menu screen display is supplied to the event determination unit 400 via the state acquisition unit 407, for example, from the power control unit that detects when the power is turned on.

  In step S502, when the event determination unit 400 acquires the menu screen display event, the event determination unit 400 refers to LUT_STATE_TRANS of the state transition holding unit 401 and transitions from the initial state to the state 100. Then, user information presentation processing corresponding to the transition destination state 100 is performed.

  In step S504, the image drawing unit 406 superimposes and displays the GUI image 100 constituting the menu screen on the initial screen 100-F displayed on the display unit 44 (FIG. 78). The GUI image 100 includes a plurality of icon ICs 500 for performing various settings. For example, the GUI image 100 includes icons such as “device connection”, “device removal”, and “time setting”.

  In step S <b> 510, the event determination unit 400 determines whether an event corresponding to device connection ′ is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “connection of device” on the menu screen (GUI image 100) has been selected by the user. If the event determination unit 400 determines that an event corresponding to the device connection 'has been acquired, the process proceeds to step S512. If the event determination unit 400 determines that an event corresponding to the device connection' is not acquired, the process proceeds to step S514. move on.

  In step S512, when the event determination unit 400 acquires an event corresponding to “device connection”, the event determination unit 400 refers to LUT_STATE_TRANS of the state transition holding unit 401 and transitions from the state 100 to the state 110 to perform user presentation processing.

  In step S516, the image drawing unit 406 switches the GUI image 100 displayed on the display unit 44 to the GUI image 110 (FIG. 79) that presents a device that can be connected to the processing board 30 and displays it. The GUI image 110 includes an icon IC 501 corresponding to a device connectable to the processing board 30 and a “decision” button BT 501 for selecting the icon IC 501. The icon IC 501 includes icons corresponding to, for example, the device A ′, the device B ′, the device C ′, and the device D ′. When the GUI image 110 is displayed, the process proceeds to step S520 shown in FIG.

  On the other hand, in step S514, when an event other than the device connection 'is input, the event determination unit 400 executes other event processing corresponding to the input other than the device connection'.

  In step S520 illustrated in FIG. 69, the event determination unit 400 determines whether an event corresponding to the selection of the device A ′ has been acquired from the user operation acquisition unit 42. That is, it is determined whether or not the icon IC 501A of the device A ′ on the menu screen has been selected by the user. If the event determination unit 400 determines that an event corresponding to the selection of the device A ′ has been acquired, the process proceeds to step S522. If the event determination unit 400 determines that an event corresponding to the selection of the device A ′ has not been acquired, the process proceeds to step S522. The process proceeds to S524.

For GUI image 110-A, for example, is device A attached to the user? Message MS502 and a “Yes / No” button BT502 for replying to this message MS502. When the GUI image 110-A is displayed, the process proceeds to step S530 shown in FIG.

  On the other hand, in step S524, the event determination unit 400 determines whether or not an event corresponding to the selection of the devices B, C, D ′... Other than the device A ′ is acquired from the user operation acquisition unit 42. That is, it is determined whether or not the devices B, C, D. If the event determination unit 400 determines that an event corresponding to the selection of the devices B, C, D... ′ Has been acquired, the process proceeds to step S526. On the other hand, if it is determined that an event corresponding to the selection of the devices B, C, D... ′ Has not been acquired, the process returns to step S520 to wait for the user's input operation.

  In step S526, the image drawing unit 406 switches the GUI image 110 displayed on the display unit 44 to the GUI images 110-B, C, D corresponding to the selected devices B, C, D. The GUI images 110-B, C, and D have the same configuration as the GUI image 110-A described above.

  In step S530 illustrated in FIG. 70, the event determination unit 400 determines whether or not operation information (event) based on “Yes” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “Yes” in the GUI image 110-A is selected by the user. If the event determination unit 400 determines that the operation information based on “Yes” is acquired, the process proceeds to step S532. If the event determination unit 400 determines that the operation information based on “Yes” is not acquired, the process proceeds to step S534.

  In step S534, the event determination unit 400 determines whether or not operation information (event) based on “No” is acquired from the user operation acquisition unit. That is, it is determined whether or not “No” in the GUI image 110-A is selected by the user. The event determination unit 400 proceeds to step S536 when determining that the operation information based on “No” has been acquired, and returns to step S530 when determining that the operation information based on “No” has not been acquired. Wait for input.

  In step S536, when the event determination unit 400 acquires an event corresponding to “No”, the event determination unit 400 refers to the LUT_STATE_TRANS of the state transition holding unit 401, transitions from the state 110 to the state 100, and performs user information presentation processing. In step S538, the GUI image 100 constituting the menu screen is displayed.

  On the other hand, when the image drawing unit 406 acquires an event based on “Yes” in step S532, the image drawing unit 406 switches the GUI image 110-A displayed on the display unit 44 to the GUI image 110-A-1 presenting the connection procedure. It is displayed (FIG. 81). The GUI image 110-A-1 is, for example, the attachment of the device A to the user. “******” message MS 503, and “Next” and “Back” button BT 503 for shifting to the previous and subsequent messages.

  In step S540, the event determination unit 400 determines whether an event corresponding to “next” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “next to GUI image 110-A-1” has been selected by the user. If the event determination unit 400 determines that an event corresponding to “next” has been acquired, the process proceeds to step S542. If it is determined that an event corresponding to “next” has not been acquired, the event determination unit 400 proceeds to step S544.

  In step S542, when the image drawing unit 406 acquires an event based on “Next”, the GUI image 110-A-2 presenting the next connection procedure is displayed on the GUI image 110-A-1 displayed on the display unit 44. And display (FIG. 82). The GUI image 110-A-2 has the same configuration as the GUI image 110-A-1 described above. Such an operation is repeated to display the GUI image 110-A-N related to the last connection procedure (step.N) (FIG. 83). The GUI image 110-A-N is composed of a message MS505 and a “complete” and “return” button BT505 for shifting to previous and subsequent messages. When the GUI image 110-A-N is displayed, the process proceeds to step S550 shown in FIG.

  On the other hand, in step S544, the event determination unit 400 determines whether an event corresponding to 'return from the user operation acquisition unit 42' has been acquired. That is, it is determined whether or not “return of GUI image 110-A-1” is selected by the user. If it is determined that the event corresponding to “return” has been acquired, the process returns to step S522 shown in FIG. 69, and the GUI image 110-A (FIG. 80) presenting the attachment confirmation of the device A is displayed again. On the other hand, if it is determined that an event corresponding to 'return' has not been acquired, the process returns to step S532 to wait for user input.

  In step S550 shown in FIG. 71, the event determination unit 400 determines whether or not operation information (event) based on “complete” is acquired from the user operation acquisition unit 42. That is, it is determined whether or not “completion of GUI image 110-A-N” has been selected by the user. The event determination unit 400 proceeds to step S552 when determining that the operation information based on “complete” has been acquired, and proceeds to step S554 when determining that the operation information based on “complete” is not acquired.

  In step S552, when the image drawing unit 406 acquires an event based on 'completion', the image drawing unit 406 switches the GUI image 110-A-N displayed on the display unit 44 to the GUI image 110-A-E presenting the connection confirmation. Displayed (FIG. 84). Does the GUI image 110-AE check the connection with the device A for the user, for example? Message MS 506 and a “Yes” or “No” button BT 506 for replying to this message MS 506. When the GUI image 110-AE is displayed, the process proceeds to step S560 shown in FIG.

That is, it is determined whether or not “return of GUI image 110-A-N” has been selected by the user. If the event determination unit 400 determines that the operation information based on 'return' has been acquired, the event determination unit 400 proceeds to step S556. On the other hand, if it is determined that the operation information based on 'return' has not been acquired, the process returns to step S550 and waits for user input.

  In step S556, when the event determination unit 400 acquires an event based on 'return', the event determination unit 400 redisplays the GUI image 110-A-N-1 for guiding the connection procedure on the previous page. Thereby, the user can reconfirm the connection procedure of the apparatus A.

  In step S560 shown in FIG. 72, the event determination unit 400 determines whether or not an event corresponding to “Yes” is acquired from the user operation acquisition unit. That is, it is determined whether or not “YES” in the GUI image 110-AE is selected by the user. If the event determination unit 400 determines that an event corresponding to “Yes” has been acquired, the process proceeds to step S562. If the event determination unit 400 determines that an event corresponding to “Yes” has not been acquired, the process proceeds to step S564.

  In step S562, when the event determination unit 400 acquires the event corresponding to “Yes”, the event determination unit 400 refers to LUT_STATE_TRANS, changes from the state 110_A to the state 120, and executes the user information presentation process.

  In step S566, the image drawing unit 406 switches the GUI image 110-AE displayed on the display unit 44 to the GUI image 120 indicating the progress of the communication establishment determination and displays it (FIGS. 85 and 86). The GUI image 120 is configured with a message MS507 that confirms the connection with the device A for the user and an icon IC507 that indicates the progress of the progress of the communication establishment determination.

If the event determination unit 400 determines that the operation information based on the establishment of communication 'has been acquired, the process proceeds to step S584. If the event determination unit 400 determines that the operation information based on the establishment of communication establishment' has not been acquired, the process proceeds to step S584. The process proceeds to S582.

  In step S584, when the event determination unit 400 acquires an event corresponding to “establishment of communication”, the event determination unit 400 makes a transition from the state 120 to the state 140 with reference to LUT_STATE_TRANS. Then, a user information presentation process corresponding to the state 140 is executed.

  In step S588, the image drawing unit 406 switches the GUI image 120 displayed on the display unit 44 to the GUI image 140 presenting establishment of communication and displays the GUI image 120 (FIG. 90). The GUI image 140 has established communication with the connected device A for the user. Message MS509 and an “OK” button BT509 for responding to the message MS509. Then, after a predetermined time has elapsed, the image drawing unit 406 switches the GUI image 140 to the GUI image 100-1 (FIG. 92) constituting the menu screen and displays it. An icon IC 500A corresponding to the connected device A is added and displayed on the GUI image 100-1. Various settings of the device A can be performed by selecting the icon IC500A.

  On the other hand, in step S582, the event determination unit 400 determines whether or not the operation information (event) based on the “communication establishment failure” is acquired from the optical communication establishment determination unit 60. If the event determination unit 400 determines that operation information based on 'communication establishment failure' has been acquired, the process proceeds to step S586. If the event determination unit 400 determines that operation information based on communication establishment failure 'is not acquired, step S586 is performed. Return to S580.

  In step S586, when the event determination unit 400 obtains an event corresponding to 'communication not established', the event determination unit 400 refers to LUT_STATE_TRANS and transitions from the state 120 to the state 150. Then, a user information presentation process corresponding to the state 150 is executed.

  In step S590, the image drawing unit 406 switches the GUI image 120 displayed on the display unit 44 to the GUI image 150 presenting that communication establishment is not established (FIG. 91). The GUI image 150 could not establish a connection with the device A for the user. Message MS510 and an “OK” button BT510 for responding to this message MS510. When the communication cannot be established, for example, the process proceeds to the process of displaying the GUI image indicating the connection procedure described above again or performing the failure diagnosis of the light emitting unit 14 and the light receiving unit 34.

That is, it is determined whether or not “return of GUI image 160-A-N” is selected. If the event determination unit 400 determines that the operation information based on 'return' has been acquired, the event determination unit 400 proceeds to step S648. On the other hand, if it is determined that the operation information based on 'return' has not been acquired, the process returns to step S640 to wait for user input.

  In step S648, when the event determination unit 400 acquires an event based on “return”, the event determination unit 400 displays a GUI image 160-A-N-1 indicating a device removal procedure on the previous page. As a result, the user can reconfirm the procedure for removing the device A.

  As described above, according to the present embodiment, the same operational effects as those of the first embodiment can be obtained. That is, in the present embodiment, information based on an event corresponding to the user's operation is presented to the user, so that the user can more accurately grasp the internal state of the optical communication system. As a result, a prompt and accurate response is possible, and the possibility of destruction or failure of the optical communication system can be reduced.
