[0042]
On the other hand, when individual execution is selected, zoom, focus, iris, extender, advanced back focus (only when the lens has a function), power supply voltage, etc. (when the lens has a function) Diagnosis of each item (only) is performed individually. The zoom controller and focus controller can also be checked.
[0043]
Hereinafter, automatic execution and individual execution of the diagnosis mode will be described in order.
[0044]
5.1. Auto-run
5.1.1. Autorun diagnostics
When the “AUTO” item is selected from the “TOTAL” frame on the “FIND Menu” screen of FIG. 7, the automatic execution process is started. That is, diagnosis of each item such as zoom, focus, iris, extender, power supply voltage, etc. is continuously and automatically performed. In the FIND system, the function attached to the lens 10 connected to the personal computer 16 is automatically recognized, and only the diagnosis item corresponding to the function of the lens 10 is diagnosed.
[0045]
During the execution of the diagnosis, the status of the lens 10 is displayed in real time. When the diagnosis is completed, the diagnosis result is displayed in three colors: green (normal), yellow (necessary adjustment), and red (repair required). The Then, about 1 second after the diagnosis result of one item is displayed, the diagnosis of the next item is started.
[0046]
Here, the processing during the diagnosis execution in the personal computer 16 and the lens 10 will be described. The CPU 50 of the personal computer 16 gives a control signal for instructing the operation of the lens 10 for executing the diagnosis of each item to the CPU 20 of the lens 10. The drive unit of the lens 10 is driven based on the control signal. During the diagnosis operation, information necessary for diagnosis such as detection values of the position detection sensors 24 and the current / voltage detection circuit 26 (see FIG. 2) is sequentially read by the CPU 20 of the lens 10, for example, some information. (For example, the position detection value of each position detection sensor 24) is transmitted to the personal computer 16 in real time, and the information is displayed in real time on the monitor 56 of the personal computer 16, and other information (for example, current detection of the current / voltage detection circuit 26). Value) is temporarily stored in the memory 28 of the lens 10. When the diagnostic operation of one unit is completed, information such as detection values stored in the memory 28 of the lens 10 is transmitted to the personal computer 16 and diagnosed by the CPU 50 of the personal computer 16 based on the information acquired during or after the diagnostic operation. The result is determined, and the diagnosis result is displayed on the monitor 56 of the personal computer 16.
[0047]
More specifically, the diagnosis of zoom is described as an example. A control signal for instructing the CPU 20 of the personal computer 16 to move the zoom from the wide end to the tele end at the maximum speed in order to perform the zoom diagnosis operation. Sent. Accordingly, the zoom drive unit is driven, and the zoom (zoom lens) moves at the maximum speed from the wide end to the tele end.
[0048]
During the movement, the CPU 20 of the lens 10 sequentially reads position detection values related to zoom from each position detection sensor 24 (see FIG. 2), transmits the position detection values to the personal computer 16 in real time, and sends them to the zoom drive unit. The supplied current value (current detection value) is sequentially read from the current / voltage detection circuit 26 (see FIG. 2), and the current value is temporarily stored in the memory 28. When the zoom reaches the telephoto end and the driving of the zoom driving unit stops, the CPU 20 of the lens 10 reads the current value stored in the memory 28 and transmits it to the personal computer 16.
[0049]
On the other hand, the CPU 20 of the personal computer 16 displays a screen as shown in FIG. 8 on the monitor 56 and displays the position detection value acquired from the lens 10 in a graph in real time in a “Wide => Tele” frame on the main screen.
[0050]
Further, the CPU 20 of the personal computer 16 determines that the zoom has moved from the wide end to the tele end based on the position detection value, and detects the operation time required for the zoom movement from the wide end to the tele end. The load required for the movement is detected based on the current value acquired from the lens 10. Then, it is determined whether the detected operation time and load are normal, whether adjustment is necessary, or whether repair is necessary. The CPU 50 obtains the operation time and load when it is determined to be normal from lens data created as a database in advance, and makes the above determination by comparing with the data.
[0051]
When the above judgment is made, for each of the operating time and load, the diagnostic results are lit next to the “TIME” and “LOAD” items in the “Wide => Tele” frame at the upper left of the diagnostic result display screen of FIG. Display by position and lighting color. For example, three rectangular display frames are arranged in a horizontal row for each of the “TIME” and “LOAD” items. If it is diagnosed as normal, the leftmost display frame lights in green. When it is diagnosed that adjustment is necessary, the center display frame is lit yellow, and when it is diagnosed that repair is necessary, the rightmost display frame is lit red. In addition, the diagnostic result is displayed in text on the right side of the diagnostic result display screen.
[0052]
By performing the same processing as described above by moving the zoom from the tele end to the wide end at the maximum speed, the zoom diagnosis is completed. If you click the “STOP” button displayed at the bottom of the “FIND Menu” screen, automatic execution is stopped.
[0053]
5.1.2. Diagnostic result display
When the diagnosis of each item such as zoom, focus, iris, extender, power supply voltage, etc. in the automatic execution is completed, the diagnosis result is displayed as shown in the main screen of FIG. If all diagnosed items are normal, “ALL OK” (not shown) is displayed on the upper left of the main screen. If any item is abnormal, the color of that item tag changes and is displayed in front. If there are two or more abnormal items, the operator switches the item tags appropriately with the mouse and confirms the contents of each.
[0054]
5.1.3. Saving data of auto-run diagnostic results
The diagnosis result data obtained by the automatic execution process can be saved in a predetermined file format (file format such as MS Excel). For example, if you click the “Save” button on the main screen of FIG. 9 with the mouse, a screen for specifying the save location and file name will be displayed, and if you specify them, the diagnostic result data is the file specified in the specified save location Saved by name. In addition, when there is an abnormality in a diagnosis item, a detailed analysis is performed at the manufacturer by sending the data file to the service representative of the manufacturer by e-mail or the like.
[0055]
5.1.4. PC processing in automatic execution
The outline of the automatic execution process in the CPU 50 of the personal computer 16 is shown in the flowchart of FIG. After performing the required initial settings (step S30), the CPU 50 turns on the diagnosis start button (selects “AUTO” in the “TOTAL” frame on the “FIND Menu” screen (see FIG. 7)) (step 7). S32), information necessary for diagnosis is acquired from the lens 10, and lens diagnosis (automatic execution process) is performed. At this time, it is determined whether or not it is normal with reference to lens data during normal operation (step S34). Then, the entire diagnosis result data is displayed on the monitor, and the lens type name, serial number, date, and diagnosis result are stored in a predetermined location of the personal computer 16 (step S38). Note that the data storage in step S38 is automatically performed to refer to the data in a diagnosis history display mode to be described later.
[0056]
5.2. Individual execution process
5.2.1. Individual execution items
For example, by selecting an item to be diagnosed from the “INDIVIDUAL” frame in the “FIND Menu” screen of FIG. 7, zoom, focus, iris, extender, advanced back focus (only when the lens 10 has a function) Each item of the power supply voltage can be diagnosed individually. In the FIND system, the functions attached to the lens 10 connected to the personal computer 16 are automatically recognized, and only the diagnostic items corresponding to the functions of the lens are displayed in the “INDIVIDUAL” frame and can be selected. ing.
[0057]

The diagnosis is started when the “Start” button on the main screen is clicked with the mouse.
[0060]
When the diagnosis is started, a control signal for instructing the zoom operation is transmitted from the CPU 50 of the personal computer 16 to the CPU 20 of the lens 10 in order to perform the zoom diagnosis operation. The zoom driving unit is driven by the control signal, the zoom moves from the wide end to the tele end, and then the zoom moves to the center of the wide end and the tele end. During the movement, the CPU 20 of the lens 10 sequentially reads the position detection value from the position detection sensor related to the zoom drive unit and transmits the position detection value to the personal computer 16 in real time.
[0061]
The CPU 50 of the personal computer 16 displays the control signal transmitted to the lens 10 and the position detection value acquired from the lens 10 in real time on the main screen of FIG. For example, the control signal value and the position detection value are displayed in a graph in the “Wide => Tele => Center” frame of the main screen, and the values are displayed by an indicator in the right frame. In the drawing, a potentiometer and two encoders (A, B) are installed as position detection sensors related to zoom.
[0062]
Further, when the zoom is moved to the center and the diagnosis operation is completed, the CPU 50 of the personal computer 16 determines whether the maximum value and the minimum value of the position detection values acquired from the lens 10 are normal or need to be adjusted. Alternatively, it is determined whether repair is necessary. And the result is displayed on the diagnostic result display screen of FIG. On the left side of the diagnostic result display screen, the maximum and minimum diagnostic values of the position detection value by the position detection sensor are displayed by the lighting position and lighting color. If it is diagnosed as normal, the leftmost display frame is green.

The CPU 50 of the personal computer 16 transmits a control signal for instructing the zoom operation to the lens 10 to move the zoom at a constant speed, obtains the output value of the encoder at that time from the lens 10, and outputs the output value to the graph display frame. Display a graph. In the graph display frame of FIG. 13, the operator can determine that the line indicating the center is normal if the line near the center of the SIN wave indicating the A-phase output signal and the SIN wave indicating the B-phase output signal. The zoom operation speed can be finely adjusted by clicking the “↑” button (speed UP) or “↓” button (speed DOWN) in the “SPEED” item in the “ARRANGEMENT” frame. Also, the horizontal axis of the graph can be changed by changing the value of the “BAWIDTH” item.
[0065]
5.2.5. ERD mode (controller diagnosis)
In the FIND system, it is possible to diagnose a controller connected to the lens 10 such as the zoom controller 14 and the focus controller 12. In this controller diagnosis, information (controller information) set or stored in the controller is read into the personal computer 16 such as an operation unit provided in the controller, a setting state of each switch, and shot (preset) data stored in the controller. Based on the information, a diagnosis is made as to whether or not the controller is normal.
[0066]
In the controller diagnosis, the interactive mode and the non-interactive mode can be selected by changing the environment setting of the software. The guidance display prompting the operator to perform a predetermined operation is performed, and the personal computer 16 determines whether or not a signal corresponding to the operation is transmitted. The diagnosis result is displayed on the monitor 56. On the other hand, when the non-interactive mode is selected, the controller information is displayed on the monitor 56 in real time, the operator arbitrarily operates the controller, and the operator confirms on the monitor 56 that the operation has been performed. Thus, a diagnosis is made as to whether the controller is normal or not at the operator's discretion. In this case, the diagnosis result is not displayed on the monitor 56.
[0067]
The case where the diagnosis of the zoom controller 14 is performed will be described as an example. As shown in FIG. 14, the “ZOOM” item is selected from the “INDIVIDUAL” frame of the “FIND Menu” screen, and the “ERD” item is selected from the “ZOOM” frame. When is selected, the ERD mode is set and a main screen as shown in FIG. 14 is displayed. When the “START” button is clicked on the main screen, controller diagnosis for the zoom controller 14 is started.
[0068]
In the main screen, a switch information display frame, a summing information display frame, a speed adjustment volume information display frame, a limit adjustment volume information display frame, a zoom shot memo information display frame, a focus shot memo information display frame, etc. are set or stored in the zoom controller 14. There is a frame for displaying each of the controller information to be set, and based on the controller information read into the personal computer 16, the setting state of each switch 44 of the zoom controller 14 and the operation unit 42 (thumling 14A, speed adjustment volume, limit adjustment volume) Alternatively, the shot data stored in the zoom controller 14 is displayed in the corresponding frame. In the non-interactive mode, the controller information is read from the lens 10 in real time, and the controller information is displayed in each frame in real time.
[0069]
An overview of the controller diagnosis process will be described with reference to the flowchart of FIG. First, the CPU 50 of the personal computer 16 determines whether or not the conversation mode is set (step S50). If NO, that is, if the non-interactive mode is determined, the CPU 50 reads controller information (operation unit and switch status) continuously from the lens 10 (step S52). The lens 10 acquires controller information from the controller to be diagnosed. Then, the information is displayed on the monitor 56 in real time (step S54). Subsequently, it is determined whether or not the end of diagnosis is instructed (step S56). If it is determined YES, the diagnosis is ended. When it determines with NO, it returns to said step S52. In the controller diagnosis in the non-interactive mode of this embodiment, each controller information is displayed in the corresponding frame in FIG. 14, and the operator determines whether there is an abnormality in the controller by confirming the displayed controller information. I do.
[0070]
If YES in step S50, that is, if it is determined that the dialogue mode is set, the CPU 50 first displays a guidance message “please press X SW” on the monitor 56 (step S58). The display portion of “X SW” indicates a predetermined operation member provided in the controller to be diagnosed (not limited to the switch). In addition, “please press” is appropriately changed to a sentence instructing an operation corresponding to the type of “X SW”.
[0071]
Then, the state of “X SW” instructing the operation is read through the lens 10 (step S60), the type of the operation member to be diagnosed, and the state of the operation member read in relation to the operation of the operation member (operation (Including the presence / absence of a signal from the member) and stored (step S62). Next, it is determined whether or not to execute diagnosis (step S64). If YES is determined, the operation member is diagnosed from the state of the operation member stored in step S62 (step S65).
[0072]
Subsequently, it is determined whether there is any other operation member that has not been diagnosed (step S66). When it determines with NO, it returns to said step S58, performs the guidance display which prompts operation of another operation member, and performs the said process. On the other hand, when it determines with NO in the said step S64, the diagnostic result diagnosed by step S65 is displayed on the monitor 56 (step S68), and a diagnosis is complete | finished.
[0073]
5.2.6. Offset diagnosis
When the “Center Check” button in the summing information display frame on the main screen of FIG. 14 is pressed, an offset diagnosis of the zoom controller 14 is performed. Although the offset diagnosis can be performed in the same manner for the focus controller 12, the offset diagnosis of the zoom controller 14 will be described here. In the offset diagnosis, the information of the thumb ring 14A of the zoom controller 14 (the control signal transmitted from the zoom controller 14 to the lens 10 corresponding to the set position of the thumb ring 14A) is read into the personal computer 16 and the thumb ring 14A is set as the reference position. It is diagnosed whether the control signal is within a certain range in the state (no operation state).
[0074]
The offset diagnosis process will be described with reference to the flowcharts of FIGS. In the flowchart of FIG. 16, the CPU 50 of the personal computer 16 first displays on the monitor 56 a warning to make the thumb ring 14A center (no thumb ring operation) (step S80). Then, after a few seconds, a display to notify the start of diagnosis is performed (step S82). Next, for a few seconds, a control signal from the zoom controller 14 and a position detection value (follow signal) detected by a position detection sensor (position detection sensor for detecting the position of the zoom lens) related to the zoom drive unit. Obtained from the CPU 20 of the lens 10, the maximum value, the minimum value, and the increase / decrease tendency are stored (step S 84).
[0075]
The drive unit includes a digital type and an analog type. When the zoom drive unit is a digital type, a digital control signal is transmitted as it is from the CPU 20 of the lens 10 to the zoom drive unit. On the other hand, when the zoom driving unit is an analog type, the CPU 20 of the lens 10 and the analog driving unit are connected via a D / A converter 80 and an amplification circuit 82 as shown in FIG. The control signal output from the CPU 20 of the lens 10 is converted into an analog signal by the D / A converter 80 and then amplified by the amplifier circuit 82, and the output signal from the amplifier circuit 82 is converted into an analog driver 86. Given to. When the lens 10 is equipped with the analog drive unit 86 as described above, in addition to the control signal and the follow signal, the output signal of the amplification circuit 82 is also sent to the CPU 20 of the lens 10 via the A / D converter 84. The output signal is transmitted to the CPU 50 of the personal computer 16.
[0076]
Next, diagnostic data is read from the lens data during normal operation held by the personal computer 16 as a database (step S86), and it is determined whether or not the control signal acquired from the lens 10 is within the standard value (step S88). If NO is determined, it is determined that the controller is abnormal (step S90), and a detailed display of the diagnosis result and diagnosis error is performed (step S100). The standard value is a range of control signal values that are allowed as a value for stopping zooming with respect to the state where the thumb ring 14A is centered, that is, the control signal to be originally taken with the thumb ring 14A being centered. It means the range of values (hereinafter the same applies to the standard values for follow signals).
[0077]
If YES is determined in step S88, it is then determined whether or not the zoom drive unit is an analog type (step S92). If NO is determined, it is then determined whether or not the follow signal acquired from the lens 10 is within the standard value (step S96). If NO is determined in step S96, the zoom drive unit (module) is determined to be abnormal (step S98). If YES is determined, it is determined to be normal, and the diagnosis result and detailed display of the diagnosis error are displayed. (Step S100).
[0078]
If YES in step S92, that is, if the zoom driving unit is determined to be an analog type, it is next determined whether or not the output signal is within a standard value (step S94). If it is determined as YES, the processing subsequent to step S96 is executed in the same manner as when it is determined as digital.
[0079]
On the other hand, if NO is determined in step S94, it is then determined whether or not the adjustment mode is entered (step S102), as shown in FIG. The operator gives an instruction as to whether or not to enter the adjustment mode. If NO is determined, an offset voltage abnormality is diagnosed (step S104), and the process returns to FIG. 16 to display details of the diagnosis result and diagnosis error (step S100).
[0080]
If YES is determined in step S102, it is then determined whether the number of trials is less than 20 (step S106). If YES is determined, an instruction to change the resistance / parameter for determining the output voltage of the amplifier circuit 82 (see FIG. 18) is given to the lens 10 (step S108), and the change instruction status is stored (step S108). Step S110). Note that by changing the resistance / parameter that determines the output voltage of the amplifier circuit 82 (see FIG. 18), the amount of voltage shift with respect to the input voltage input to the amplifier circuit 82, the magnitude of the gain with respect to the input voltage, and the like are changed. be able to.
[0081]
Subsequently, the output signal of the amplifier circuit 82 is read from the lens 10 (step S112), and it is determined whether or not the output signal is within the standard value (step S114). When it is determined NO, the processing from step S106 is repeated.
[0082]
On the other hand, when it determines with YES in step S114, the display which instruct | indicates that the thumb ring 14A is set to the tele side (tele end) is performed (step S116). Then, the output signal of the amplifier circuit 82 is read from the lens 10 (step S118), and it is determined whether or not the output signal is within the standard value (step S120). If NO is determined, a display for instructing the thumb ring 14A to be the center is performed (step S128), and the processing from step S106 is repeated.
[0083]
If YES is determined in step S120, a display for instructing the thumb ring 14A to be on the wide side (wide end) is performed (step S122). Then, the output signal of the amplifier circuit 82 is read, and it is determined whether or not the output signal is within the standard value (step S124). When it determines with NO, the display which instruct | indicates to make the thumb ring 14A into a center is performed (step S128), and it returns to said step S106.
[0084]
On the other hand, if YES is determined in step S126, that is, if all of the follow signal, the tele end signal, and the wide end output signal are within the standard values, it is determined that the offset abnormality has been repaired (step S130). Referring back to FIG. 16, the diagnostic result and the diagnostic error are displayed in detail (step S100).
[0085]
If NO is determined in step S106, the lens 10 is instructed to return the amplification circuit 82 to the original state (step S132), and it is determined that the offset abnormality cannot be repaired (step S134). Returning to FIG. 16, the diagnosis result and diagnosis error details are displayed (step S100).
