  FIG. 3 is a table showing the structure of the moving image data and the standard processing time described above.

  In the MFP 1, various sensors 109 respond to various errors such as paper jam (jam or JAM), toner bottle replacement, or paper replenishment. Removing the exterior door to open the external door, internal door removal and lever operation (internal removal), sensor abnormal state release (sensor release), sensor reset (reset), internal door return processing (internal return), A series of a plurality of processes such as a process of returning the external door (exterior return) is required, and the moving image data is composed of image data indicating these processes. In addition, for each process, a standard processing time is set in advance as a time required for a cancellation process by an unskilled user, and is stored in the standard processing time table holding unit 106 c of the storage unit 106.

  In the example of FIG. 3, for a paper jam (JAM) error, a plurality of sensors (sensors 1, 2,... N,...) Are provided depending on the location of the paper jam to replace the toner bottle or supply the paper. In this case, a plurality of sensors (sensors a, b,..., Sensors A, B...) Are provided, and moving images corresponding to the respective sensors are held. For example, as standard processing time for an error when the sensor 1 is turned on, exterior removal: T11, internal removal: T12, sensor release: T13, resetting: T14, internal return: T15, exterior removal: T16 are set. Yes.

  FIG. 4 is a proficiency level table for each user. For a user who has been authenticated by the user authentication unit 105, from the processing time required when the user has performed error cancellation processing corresponding to each sensor 109 in the past, exterior removal, internal return, sensor cancellation, resetting, internal The proficiency level for each process of returning and removing the exterior is held at the table. In addition, the proficiency level table is updated each time the user performs an error canceling process corresponding to the sensor 109.

  In the example of FIG. 4, the proficiency level for the user A is shown. In this embodiment, the proficiency level is set such that “standard” is the lowest level, and the proficiency level increases in the order of “high 1” “high 2” “high 3” “high 4” “high 5”. ing. For user A, the proficiency level regarding the error when the sensor 1 is turned on is as follows: exterior removal: standard, internal removal: high 2, sensor release: high 1, reset: high 3, internal return: high 2, exterior Return: High 1

  The proficiency level shown in FIG. 4 is set as shown in FIG. That is, with respect to a process for canceling an error corresponding to an abnormality of a certain sensor, the standard processing time (Ts) shown in FIG. 2 when the error canceling process is performed without proficiency and the actual time required for the user to cancel the error A difference value (Ts−PT) of the processing time (PT) is obtained, and the proficiency level is determined by comparing the value with threshold values ThX1 to ThX4 for determining the proficiency level.

  Specifically, as shown in FIG. 5, for the sensor 1, the proficiency is “standard” when (Ts1−PT) ≦ 0, and the proficiency is “high 1” when 0 <(Ts1−PT) <Th11. , When Th11 ≦ (Ts1−PT) <Th12, the proficiency is “high 2”, and when Th12 ≦ (Ts1−PT) <Th13, the proficiency is “high 3” and Th13 ≦ (Ts1−PT). When Th14, the proficiency level is set to “high 4”, and when Th14 ≦ (Ts1-PT), the proficiency level is set to “high 5”. The same applies to the other sensors 109.

  The processing time required for each process of exterior removal, interior removal, sensor release, resetting, internal return, and exterior return is the time from the start to the end of each process, and the measurement method is not particularly limited. In this embodiment, in addition to the error detection sensor 109, the MFP 1 is also provided with a sensor that detects the opening / closing of the external door and the internal door, and acquires a time stamp when the state of these sensors changes. What is necessary is just to calculate processing time. For example, the processing time for removing the exterior can be calculated as the time from when the external door is opened until the internal door is opened.

  The moving image playback time is set in advance according to each proficiency level. In this embodiment, the moving image playback time is adjusted based on the elapsed time from the previous execution of the error canceling process.

  FIG. 6 is a table showing the correction coefficient of the moving image reproduction time based on the elapsed time since the previous error cancellation processing.

  In general, a person cannot correctly understand the procedure for canceling an error corresponding to the abnormality of the sensor 109 with time, and as the time elapses, the process procedure is forgotten and the proficiency level is lowered. Therefore, in this embodiment, the correction coefficient for extending the playback time of the moving image is set as shown in FIG. 6 in accordance with the elapsed time from the previous error canceling process. The correction coefficient is set from 0 (no correction) to +4. For example, the correction coefficient for an error when the sensor 1 is turned on has an elapsed time of less than 1 week (~ 1W): 0, 1 week or more and less than 2 weeks (~ 2W): +1, 2 weeks or more and less than 4 weeks (~ 4W): +2, 4 weeks or more and less than 8 weeks (~ 8W): +3, 8 weeks or more and less than 16 weeks (~ 16W): +4, 16 weeks or more (16W ~ ): +4. The larger the number, the longer the playback time. Different correction coefficients are set according to the sensors 109.

  Furthermore, in this embodiment, rewind playback is possible when playing back a moving image based on a user operation. When such rewinding is performed, the user is considered to have a low level of proficiency or a low level of proficiency regarding the error canceling process. Correct the playback time.

  FIG. 7 is a table that defines correction coefficients for adjusting the playback time when such rewinding is performed. Correction coefficients are set according to the number of screen frames for rewinding. Adjustment is made so that the larger the rewind amount, the longer the reproduction time (lowering the reproduction speed).

  For example, for example, when the sensor 1 is turned on, the correction coefficient based on the number of rewind frames is 0 when the number of rewind frames is 0 (no rewind): 0, when the number of rewind frames exceeds 0 and is 2 or less. : +1, when the number of rewind frames is more than 2 and 4 or less: +2, when the number of rewind frames is more than 4 and less than 6: +3, when the number of rewind frames is more than 6, it is +4.

  The number of rewind frames is measured every time rewinding occurs, and the latest data is stored in association with the user.

  In this embodiment, the playback speed can be reduced in addition to the rewind playback based on the user operation. When the playback speed is instructed, the instruction is stored in association with the user, and the next time When the same video data is played back, the playback time is adjusted so that the playback time becomes longer (lowering the playback speed). In this case, it is possible to instruct the reproduction speed down step by step, and the correction coefficient may be changed according to the ratio of the reproduction speed reduction in the same manner as the correction coefficient according to the number of rewind frames shown in FIG. .

  Further, in this embodiment, the forward playback or the playback speed can be increased based on the user operation, and when the forward or the playback speed is instructed, the advanced level is stored in the proficiency table holding unit 106b of the storage unit 106. It is designed to correct the user's proficiency level. As the correction of the proficiency level, for example, the current proficiency level can be increased by one step. Similarly to the case of rewinding, the proficiency level may be corrected so that the reproduction speed is increased stepwise in accordance with the number of advance frames. Further, it is possible to instruct step-by-step to increase the reproduction speed, and the proficiency level may be corrected according to the rate of increase in reproduction speed.

  FIG. 8 is a flowchart showing a reproduction time determination process when the MFP 1 reproduces moving image data. The operations shown in the flowcharts of FIG. 8 and FIG. 9 and thereafter are executed when the CPU 101 of the MFP 1 operates according to an operation program stored in the ROM 102 or the like.

  In step S01, the statuses of the various sensors 109 attached to the MFP 1 are acquired. In step S02, the moving image data necessary for releasing the abnormal sensor from the acquired state of the sensor 109 is selected and acquired from the moving image data held in the moving image data holding unit 106a. Next, in step S03, for the user authenticated by the user authentication unit 105, the proficiency level of the corresponding sensor (error) processing is taken out from the proficiency level table held in the proficiency level table holding unit 106c, and the playback time is calculated. Decide. The reproduction time is preset according to the proficiency level.

  Next, in step S04, the playback time is corrected (adjusted) with reference to the table of FIG. 6 based on the elapsed time from the previous process, and in step S05, the rewind or the playback speed is reduced in the previous process. In this case, the playback time is corrected (adjusted) according to the number of rewind frames or the playback speed is lowered, and after the playback time is determined in step S06, the process is terminated.

  FIG. 9 is a flowchart showing the processing of the MFP 1 when reproducing moving image data.

  In step S11, the moving image data is reproduced at the reproduction time determined in step S06 in FIG. In step S12, it is determined whether rewinding has occurred based on a user instruction. If rewinding does not occur (NO in step S12), the process proceeds to step S14. If rewinding has occurred (YES in step S12), the number of rewind frames is stored in the storage unit 106 in association with the user in step S13, and then the process proceeds to step S14.

  In step S14, it is determined whether or not the reproduction speed is reduced based on the user instruction. If the reproduction speed does not decrease (NO in step S14), the process proceeds to step S16. When the reproduction speed is reduced (YES in step S14), in step S15, the fact is associated with the user and stored in the storage unit 106, and the process proceeds to step S16.

  In step S16, it is determined based on the user's instruction whether the forward playback or the playback speed increase has occurred. If the forward playback or the increase in playback speed does not occur (NO in step S14), the process ends. If the forward playback or the playback speed increase occurs (YES in step S16), the skill level associated with the user is corrected in step S17, and then the process ends.

  As described above, in this embodiment, when an error is detected by any of the error detection sensors during the operation of the authenticated user, moving image data indicating a handling method corresponding to the detected error is acquired. It is possible to reproduce appropriate video data for error cancellation. In addition, the playback time of the video data is determined based on the error cancellation processing time stored in association with the user and the standard error cancellation processing time, and the video data is played back at the determined playback time. For example, if the user's error clearing processing time is short, the user is considered proficient in the error clearing operation, so it is possible to take measures such as shortening the playback time, depending on the type of error. Thus, it is possible to efficiently reproduce the moving image data in accordance with the user's proficiency in the error canceling operation.

  In addition, the playback time is adjusted based on the user's proficiency level and the elapsed time from the previous playback time of the video data. The higher the proficiency level, the shorter the playback time and the longer the elapsed time from the previous playback time, Since the reproduction time becomes longer, the moving image data can be reproduced more efficiently.

  Furthermore, if rewind playback or playback speed reduction is instructed based on the user's instruction, the user may not be proficient in the error canceling process or the proficiency level may be reduced. When the next playback is played at a reduced playback speed, and the user is instructed to postpone or increase the playback speed based on the user's instruction, the user is considered to be highly proficient in the error canceling process, so the proficiency is corrected. Video data can be played back more efficiently.

  The method for adjusting the reproduction time of the moving image data is not particularly limited, but as an example, there is a method of thinning out the screen frames of the moving image data as shown in FIG. FIG. 10A shows the screen frame 201 when thinning is not performed, FIG. 10B shows a thinned state, and shows a frame in which the screen frame 201a shown by hatching is thinned. As shown in FIG. 10, the display time (moving image playback time) of all screen frames can be shortened by thinning out the screen frame 201a. As the proficiency level increases, the number of screen frames to be thinned increases (the simple thinning rate increases).

  As another method for adjusting the reproduction time of the moving image data, there is a method of increasing the reproduction speed as shown in FIG. That is, when the time for displaying the screen frames 201 of the number shown in FIG. 11A is set as the standard reproduction time, as shown in FIG. 11B, the display for each frame increases as the proficiency level increases. By shortening the time, the display time of all frames, that is, the reproduction time is shortened.

  As yet another method for adjusting the playback time of moving image data, the playback time may be shortened by combining and displaying a plurality of screen frames on one screen.

  FIG. 12 is a flowchart showing the state confirmation process of each sensor 109 performed by the MFP 1 when measuring the proficiency level.

  In step S21, the state of each sensor 109 is confirmed. In step S22, it is determined whether or not the sensor 1 is abnormal, in other words, whether or not an error has occurred. If no error has occurred (NO in step S22), the process proceeds to step S25.

  If an error has occurred (YES in step S22), in step S23, proficiency level data of sensor 1 of the logged-in user (for example, user A) is acquired from the proficiency level table, and in step S24, user A After the sensor 1 proficiency level measurement flag is turned ON, the process proceeds to step S25.

  In step S25, it is determined whether an error has occurred in the sensor 2. If no error has occurred (NO in step S25), the process proceeds to step S28.

  If an error has occurred (YES in step S25), proficiency level data for user A's sensor 2 is acquired in step S26, and in step S27, the sensor 2 proficiency level measurement flag for user A is turned ON. Proceed to step S28.

  In step S28, it is determined whether an error has occurred in the sensor 3. If no error has occurred (NO in step S28), the process proceeds to determination for the next sensor.

  If an error has occurred (YES in step S28), proficiency level data of the sensor 3 of the user A is acquired in step S29, and after the sensor 3 proficiency level measurement flag of the user A is turned ON in step S30, Proceed to the determination for the next sensor.

  Similarly, it is determined whether an error has occurred for each sensor. If an error has occurred, the proficiency level measurement flag for that sensor is turned ON.

  In step S31, it is determined whether or not an error has occurred for the last sensor X. If an error has occurred (YES in step S31), proficiency level data for sensor A of user A is acquired in step S32. In step S33, the sensor X proficiency level measurement flag of the user A is turned ON, and the process ends.

  FIG. 13 is a flowchart showing proficiency level measurement processing performed by the MFP 1.

  In step S51, a proficiency level measurement flag of each sensor is acquired for the user (for example, user A). With the processing of the flowchart of FIG. 12, the proficiency level measurement flag is ON for the sensor 109 in which an error has occurred.

  In step S52, it is determined based on the acquired proficiency level measurement flag whether the sensor 1 proficiency level measurement flag is ON. If it is ON (YES in step S52), it is determined in step S53 whether or not the exterior removal is completed. If not (NO in step S53), the process waits until it is completed. When completed (YES in step S53), after calculating the processing time T10 in step S54, the process proceeds to step S55.

  In step S55, it is determined whether the internal removal has been completed. If not completed (NO in step S55), the process waits until it is completed. When completed (YES in step S55), an end time T11 is acquired in step S56. In the same manner, the end time of each process of sensor release, reset, and internal return is acquired.

  In step S57, it is determined whether or not the exterior return is finished. If not finished (NO in step S57), the process waits until it is finished. When completed (YES in step S57), an end time T16 is acquired in step S58.

  Next, in step S59, the proficiency level of each process is calculated. As shown in FIG. 4, the proficiency level is determined by comparing the difference between the standard processing time of each process and the processing time PT required for each process with a threshold value. In step S59, the processing time required for each process may be calculated, and the proficiency level may be calculated.

  Next, in step S60, the calculated proficiency level is overwritten and updated by the proficiency level in the proficiency level table.

  If the sensor 1 proficiency level measurement flag is not ON in step S51 (NO in step S51), the process proceeds to step S61 to determine whether the sensor 2 proficiency level measurement flag is ON. If it is ON (YES in step S61), it is determined in step S62 whether or not the exterior removal is completed. If not (NO in step S62), the process waits until it is completed. When completed (YES in step S62), the processing time T20 is calculated in step S63, and then the process proceeds to step S64.

  In step S64, it is determined whether or not the internal removal is completed. If not completed (NO in step S64), the process waits until it is completed. When completed (YES in step S64), a processing time T21 is calculated in step S65. In the same manner, the processing time of each process of sensor release, resetting, and internal return is calculated.

  In step S66, it is determined whether or not the external return is finished. If not finished (NO in step S66), the process waits until it is finished. When completed (YES in step S66), a processing time T26 is calculated in step S67.

  Next, after calculating the proficiency level of each process in step S68, the calculated proficiency level is overwritten and updated in the proficiency level table in step S69.

  If the sensor 2 proficiency level measurement flag is not ON (NO in step S61), it is determined whether or not the sensor 3 proficiency level measurement flag is ON. If it is ON, processing similar to steps S53 to S60 is performed. In this way, it is determined whether or not the proficiency level measurement flag is ON for each sensor. If any sensor is ON, the proficiency level of each process from the exterior removal to the exterior return for the sensor is measured and the proficiency level is determined. Reflect on the table.

  If there is no sensor whose proficiency level measurement flag is ON before the last sensor X, it is determined in step S70 whether the sensor X proficiency level measurement flag is ON. If it is not ON (NO in step S70), the process is terminated. If it is ON (YES in step S70), it is determined in step S71 whether or not the exterior removal is completed. If not (NO in step S71), the process waits until it is completed. When the process is completed (YES in step S71), the processing time TX0 is calculated in step S73, and then the process proceeds to step S73.

  In step S73, it is determined whether the internal removal has been completed. If not completed (NO in step S73), the process waits until it is completed. When completed (YES in step S73), a processing time TX1 is calculated in step S74. Thereafter, the processing time of each process of sensor release, resetting, and internal return is calculated in the same manner.

  In step S75, it is determined whether or not the exterior return is finished. If not finished (NO in step S75), the process waits until it is finished. When completed (YES in step S75), a processing time TX6 is calculated in step S76.

  Next, after the proficiency level of each process is calculated in step S77, the calculated proficiency level is overwritten and updated with the proficiency level in the proficiency level table in step S78, and the process ends.
