The communication I / F unit 112 can communicate with a computer connected to the Internet via the network 2.

  The facsimile unit 117 is connected to a public switched telephone network (PSTN) and transmits facsimile data to the PSTN or receives facsimile data from the PSTN. The facsimile unit 117 stores the received facsimile data in the HDD 116 or outputs it to the image forming unit 140. The image forming unit 140 prints the facsimile data received by the facsimile unit 117 on a sheet. Further, the facsimile unit 117 converts the data stored in the HDD 116 into facsimile data, and transmits the facsimile data to a facsimile apparatus connected to the PSTN.

  The card I / F 118 is mounted with a flash memory 118A. The CPU 111 can access the flash memory 118A via the card I / F 118. The CPU 111 loads the program recorded in the flash memory 118A attached to the card I / F 118 to the RAM 114 and executes it. Note that the program executed by the CPU 111 is not limited to the program recorded in the flash memory 118A, and the program stored in the HDD 116 may be loaded into the RAM 114 and executed.

  FIG. 4 is a functional block diagram illustrating an example of functions of the CPU included in the MFP, together with data stored in the HDD. Referring to FIG. 4, CPU 111 provided in MFP 100 includes a user authentication unit 51 for authenticating a user who operates MFP 100, a reproduction instruction reception unit 53 that receives a reproduction instruction for instructing reproduction of a moving image, and a moving image.

  The HDD 116 stores a plurality of moving images 83 in advance. Here, the plurality of moving images 83 are moving images obtained by photographing the operation of the MFP 100 or represented by animation. The plurality of moving images 83 will be described using moving images related to the operation of the MFP 100 as an example, but may be arbitrary moving images such as a meeting moving image.

  User authentication unit 51 authenticates a user who operates MFP 100. The user who operates MFP 100 includes a user who operates operation panel 160 and a user who operates PC 200, 200 </ b> A, 200 </ b> B to remotely operate MFP 100. In the following description, a case where the user operates PC 200 will be described as an example of a user who operates PC 200, 200A, 200B to remotely operate MFP 100.

  In order to authenticate the user who operates the operation panel 160, the user authentication unit 51 receives the authentication information when the authentication information is input to the operation unit 160B. When a user operating PC 200 inputs authentication information to PC 200, PC 200 transmits the authentication information to MFP 100, so that authentication information is received by communication I / F unit 112. The user authentication unit 51 receives authentication information received from the PC 200 by the communication I / F unit 112. The authentication information is a set of user identification information and a password. Note that biometric information such as fingerprints, irises, and vein patterns may be used as the authentication information.

  The user authentication unit 51 authenticates if the same authentication information as the accepted authentication information is stored in the HDD 116, but does not authenticate if it is not stored. When authenticating, the user authenticating unit 51 permits a user who operates the MFP 100 to log in. Here, when authenticating and permitting login, the user authentication unit 51 outputs user identification information included in the authentication information to the reproduction unit 59.

  When the user authentication unit 51 permits login, the CPU 111 accepts an operation input to the operation unit 160B or an operation received by the communication I / F unit 112 from the PC 200 by the authenticated user until the user logs out. It is treated as an input operation. The authentication information may be stored in an authentication server connected to the network 2 and the authentication server may be requested to perform authentication.

  When the authenticated user operates the operation unit 160B, the reproduction instruction reception unit 53 receives a reproduction instruction input by the user to the operation unit 160B and outputs the received reproduction instruction to the reproduction unit 59. When the authenticated user operates PC 200 to remotely operate MFP 100, communication I / F unit 112 receives a playback instruction received from PC 200 and outputs the received playback instruction to playback unit 59. The reproduction instruction is a command for instructing reproduction of any of the plurality of moving images 83 stored in the HDD 116, and moving image identification information for identifying one of the plurality of moving images 83 stored in the HDD 116. including. For example, a list screen that displays the moving image identification information of each of the plurality of moving images 83 stored in the HDD 116 is displayed on the display unit 160A or transmitted to the PC 200 via the communication I / F unit 112. A list screen may be displayed, and one of the plurality of moving images 83 may be specified from the list screen on which the user is displayed. Here, since the moving image 83 is a moving image obtained by photographing an operation of the MFP 100 or represented by an animation, the moving image identification information is used as an operation name, and the list screen is a help screen.

  When the reproduction instruction is input from the reproduction instruction receiving unit 53, the reproduction unit 59 reads out the moving image 83 specified by the moving image identification information included in the reproduction instruction from the HDD 116 and reproduces it. When the moving image 83 is compressed data, the playback unit 59 decodes the compressed data. Here, the moving image 83 stored in the HDD 116 has a standard frame rate for reproduction indicating the number of frames reproduced per second as 12 fps, and the moving image 83 stored in the HDD 116 is reproduced at 12 fps. The playback method is called normal playback. In addition, the playback unit 59 includes a slow playback unit 61, a thinning unit 63, and an emergency playback unit 65. Details of these will be described later. The reproduction unit 59 displays the reproduced moving image on the display unit 160A when the authenticated user operates the operation unit 160B, and reproduces the image when the authenticated user operates the PC 200 to remotely operate the MFP 100. The moving image is transmitted to the PC 200 via the communication I / F unit 112 and displayed on the PC 200.

  The state detection unit 57 detects the state of the MFP 100, for example, the state where the front panel of the MFP 100 is opened, the state where a paper jam has occurred, and the like. The front panel is provided on the front surface of MFP 100, and image forming unit 140 is exposed when front panel is opened. For example, it is opened when the user performs an operation to replace toner or when a jammed paper is removed. Status detection unit 57 detects a predetermined status of MFP 100 and outputs a status code for identifying the detected status of MFP 100 to playback unit 59.

  When the status code is input from the status detection unit 57, the emergency playback unit 65 plays back a predetermined moving image corresponding to the input status code. Specifically, a state table 85 that associates the state code with the moving image 83 is stored in the HDD 116 in advance, and the emergency playback unit 65 determines the moving image 83 corresponding to the state code with reference to the state table. And normal playback.

  For example, the status table associates a moving image obtained by replacing the toner with a status code indicating that the front panel is opened, and indicates a status where a paper jam has occurred, but the status code indicates an operation for removing the jammed paper. Associate a video that has been captured. Therefore, since the moving image is automatically reproduced according to the state of MFP 100, the user does not need to input a reproduction instruction and can understand the operation only by looking at the moving image.

  The process execution unit 73 can execute a plurality of processes. The plurality of processes include a printing process when MFP 100 functions as a printer, a copying process when functioning as a copier, a facsimile transmission / reception process when functioning as a facsimile machine, and a scanning process for functioning as a scanner. Here, a command to be executed by the process execution unit 73 is referred to as a job, and the process execution unit 73 executes a process when a job is input. The process execution unit 73 outputs an execution signal indicating that the process is being executed to the reproduction unit 59 while the process is being executed. The execution signal includes process identification information for identifying the process being executed by the process execution unit 73.

  The job reception unit 71 receives a job and outputs the received job to the process execution unit 73. Job accepting unit 71 accepts a job that the user inputs to operation unit 160B from operation unit 160B, and communication I / F unit 112 receives a job that the user inputs to PCs 200, 200A, and 200B to remotely operate MFP 100. The job is received from the communication I / F unit 112, and when the facsimile unit 117 receives the facsimile data, the job is received from the facsimile unit 117. Therefore, the job accepted by the job accepting unit 71 is not limited to the job input by the user authenticated by the user authenticating unit 51.

  While the execution signal is input from the process execution unit 73, the thinning unit 63 thins out some of the plurality of frames included in the moving image 83 to be reproduced. The moving image 83 to be reproduced includes a moving image reproduced by the emergency reproducing unit 65. The moving image 83 includes a plurality of frames capable of reproducing 12 frames per second, and a frame priority is assigned in advance to each of the plurality of frames. The thinning unit 63 thins out a frame having a frame priority lower than a threshold among a plurality of frames included in the moving image 83 to be reproduced, and does not reproduce the thinned frame. For example, the frame priority of a frame in which a complicated operation or an operation requiring fine work is photographed is increased, and the frame priority of consecutive frames with little image change is decreased. By thinning out consecutive frames with little image change, the time for displaying similar images can be shortened. In addition, since an image with little change in image is thinned out, it is possible to display almost the same image as when the frame rate is not lowered.

  In addition, a threshold value may be assigned in advance for each user identification information, and the threshold value may vary depending on the user. For this reason, even if it is the same moving image, the number of frames reproduced by the user can be varied. For example, a large threshold value is assigned to a user who can use the MFP 100, and a small threshold value is assigned to a user who uses the MFP 100 less frequently. The frame priority may be given not in each of a plurality of frames included in the moving image 83 but in a section such as a time from the start.

  While the execution signal is input from the processing execution unit 73, the slow reproduction unit 61 reproduces the moving image 83 to be reproduced with a reduced frame rate. The moving image 83 to be reproduced includes a moving image 83 in which frames are thinned out by the thinning unit 63. The slow playback unit 61 refers to the frame rate definition table stored in the HDD 116, determines the frame rate corresponding to the process specified by the process identification information included in the execution signal, and the moving image 83 at the determined frame rate. Play. The frame rate definition table associates a frame rate with each of a plurality of types of processing.

  FIG. 5 is a diagram illustrating an example of a frame rate definition table. Referring to FIG. 5, the frame rate definition table includes an item of processing type and an item of frame rate. The frame rate “12 fps” is associated with “no processing” indicating that the processing is not being executed by the processing execution unit 73, the frame rate “4 fps” is associated with the print processing, and the facsimile reception processing is performed. The frame rate “10 fps” is associated, and the frame rate “8 fps” is associated with the remote operation.

  The frame rate for the type of processing may be determined by the load on the CPU 111 when processing is executed. For processing with a heavy load on the CPU 111, the ratio of the load that can be assigned to the CPU 111 to reproduce a moving image is reduced, and the frame rate is reduced. Here, the ratio of the load that can be allocated to the CPU 111 for reproducing a moving image is 100% for “no processing”, 30% for print processing, 80% for facsimile reception processing, remote operation 60%. The load on the CPU 111 for rendering one frame is fixed, and the load on the CPU 111 increases as the frame rate increases. For this reason, by setting the frame rate according to the load of the processing being executed, it is possible to prevent frame skipping from occurring without the CPU 111 drawing a frame. In other words, all the frames of the moving image 83 to be reproduced can be displayed.

  The slow playback unit 61 reproduces the moving image 83 with a reduced frame rate. However, since the frame reproduced by the thinning unit 63 is thinned out, the moving image is compared with the case where the frame is not thinned out. The playback time of 83 can be shortened. For example, in the case of print processing, the frame rate is “12 fps” in normal reproduction, but the frame rate is “4 fps”. For this reason, if slow playback is performed without skipping frames, the playback time will be three times the playback time during normal playback, but if the number of frames is reduced to one third by skipping frames, the playback time will be This is the same as normal playback without thinning.

  FIG. 6A to FIG. 6D are diagrams schematically illustrating CPU load distribution. FIG. 6A shows the load distribution of the CPU 111 when only moving images are reproduced. Referring to FIG. 6A, it takes 1/12 seconds to draw one frame, and the CPU cannot afford to perform other processing. If another process is executed in this state, it can be seen that at least one of the 12 frames is not drawn. FIG. 6B shows the load distribution of the CPU 111 when print processing and moving image reproduction are executed. When the print process is executed, 30% is allocated to the process of reproducing a moving image, so that a time for drawing four frames is secured. FIG. 6C shows load distribution of the CPU 111 when facsimile reception processing and moving image reproduction are executed. When the facsimile reception process is executed, 80% is allocated to the process of reproducing a moving image, so that a time for drawing 10 frames is secured. FIG. 6E shows load distribution of the CPU 111 when remote operation processing and moving image playback are executed. When the remote operation process is executed, 60% is allocated to the process of reproducing a moving image, so that a time for drawing 8 frames is secured.

  Returning to FIG. 4, the thinning-out unit 63 and the slow playback unit 61 play by reducing the frame thinning and the frame rate on condition that the permission receiving unit 55 receives permission from the authenticated user. The permission receiving unit 55 displays an inquiry screen. When the authenticated user operates the operation unit 160B, an inquiry screen is displayed on the display unit 160A. When the authenticated user operates the PC 200 to remotely operate the MFP 100, the inquiry screen is displayed on the communication I / F unit 112. To the PC 200 and display on the PC 200.

  FIG. 7 is a diagram illustrating an example of an inquiry screen. The inquiry screen includes a message “Are you sure you want to adjust the frame rate?”, A button with characters “Yes” and a button with characters “No”.

  Returning to FIG. 4, when the authenticated user operates the operation unit 160B, the permission receiving unit 55 inputs an operation for instructing a button on which a character “Yes” is displayed on the inquiry screen to the operation unit 160B. , Accept permission. When the authenticated user operates the PC 200 to remotely operate the MFP 100, the permission receiving unit 55 inputs an operation for instructing a button on which an “Yes” character is displayed on the inquiry screen to the PC 200. Since the permission signal is transmitted to MFP 100, permission is accepted from communication I / F unit 112.

  FIG. 8 is a flowchart illustrating an example of the flow of the moving image reproduction process. The moving image reproduction process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes a moving image reproduction program. Referring to FIG. 8, CPU 111 determines whether or not a user login has been detected. Login is detected when user authentication is successful and login is permitted. The process waits until login is detected (NO in step S01). If login is detected (YES in step S01), the process proceeds to step S02. In other words, the processing after step S02 is processing executed on condition that the user logs in to MFP 100.

  In step S02, it is determined whether a reproduction instruction has been accepted or whether a predetermined state of MFP 100 has been detected. If a reproduction instruction is accepted, the process proceeds to step S03. The reproduction instruction is a reproduction instruction input to the operation unit 160B by the user when the user operates the operation unit 160B, or the communication I / F unit 112 is connected to the PC 200 when the user operates the PC 200 to remotely operate the MFP 100. Including a playback instruction received from. In step S02, if a predetermined state of MFP 100 is detected, the process proceeds to step S03. However, if a reproduction instruction is not received and a predetermined state of MFP 100 is not detected, the process proceeds to step S04. The predetermined state of the MFP 100 includes, for example, a state where the front panel of the MFP 100 is opened and a paper jam has occurred.

  In step S03, it is determined whether the job is being executed. Here, it is determined whether or not a process other than the process of reproducing a moving image is being performed. If the job is being executed, the process proceeds to step S12; otherwise, the process proceeds to step S08. When the process proceeds to step S08, the CPU 111 executes only a process for reproducing a moving image. When the process proceeds to step S12, the CPU 111 executes a process for reproducing a moving image and another process. Is the case.

  In step S04, as in step S03, it is determined whether or not the job is being executed. If the job is being executed, the process proceeds to step S16; otherwise, the process proceeds to step S05. When the process proceeds to step S05, the CPU 111 does not process anything. The process proceeds to step S16 when the CPU 111 is executing a process other than the process of reproducing a moving image. In step S16, it is determined whether the job being executed has ended. If the job being executed has ended, the process proceeds to step S17. If the job has not ended, the process returns to step S02. This is because a playback instruction may be accepted during execution of a job.

  In step S05, it is determined whether a job is accepted. If a job is accepted, the process proceeds to step S06; otherwise, the process returns to step S02. In step S06, execution of the process defined by the job accepted in step S05 is started. Then, it is determined whether or not a moving image is being reproduced (step S07). If a moving image is being reproduced, the process proceeds to step S12; otherwise, the process proceeds to step S16.

  On the other hand, in step S08, in accordance with the reproduction instruction accepted in step S02, the moving image 83 specified by the moving image identification information included in the reproduction instruction is read from the HDD and is normally reproduced. If a predetermined state of MFP 100 is detected in step S02, moving image 83 specified by the moving image identification information associated with the predetermined state is read from HDD by state table 85 stored in HDD 116. Play normally. The process proceeds to step S08 when the job is not executed. In this case, even if a load for normal reproduction of the moving image 83 is applied to the CPU 111, frames are not drawn and frames are not skipped.

  In step S09, it is determined whether a job has been accepted. If the job is accepted, the process proceeds to step S10. Otherwise, the normal reproduction is continued, and the process proceeds to step S11. In step S11, it is determined whether or not the playback of the moving image has ended. If the reproduction of the moving image is completed, the process proceeds to step S17; otherwise, the process returns to step S09. In step S17, it is determined whether logout has been detected. If logout is detected, the process is terminated; otherwise, the process returns to step S02. In step S10, execution of the process defined in the job accepted in step S09 is started.

  In step S12, an inquiry screen is displayed. Display to authenticated users who are allowed to log in. Specifically, when the authenticated user operates the operation unit 160B, an inquiry screen is displayed on the display unit 160A, and when the authenticated user operates the PC 200 to remotely operate the MFP 100, the reproduced moving image Is transmitted to the PC 200 via the communication I / F unit 112 and displayed on the PC 200.

  It is then determined whether permission has been accepted. If permission is accepted from operation unit 160B or communication I / F unit 112, the process proceeds to step S14; otherwise, the process proceeds to step S15. In step S15, in accordance with the reproduction instruction accepted in step S02, the moving image 83 specified by the moving image identification information included in the reproduction instruction is read from the HDD and normally reproduced, and the process proceeds to step S16. If a predetermined state of the MFP 100 is detected in step S02, the moving image 83 specified by the moving image identification information associated with the predetermined state is read from the HDD by the state table 85 stored in the HDD 116. Play normally. The process proceeds to step S15 when a job is being executed. For this reason, since the load given to the CPU 111 exceeds the capability of the CPU 111, all of the plurality of frames included in the moving image 83 may not be drawn. In step S14, a parallel reproduction process is executed, and the process proceeds to step S16. The parallel reproduction process will be described later.

  FIG. 9 is a flowchart illustrating an example of the flow of parallel reproduction processing. The parallel reproduction process is a process executed in step S14 of FIG. Referring to FIG. 9, CPU 111 determines a frame rate (step S21). The moving image identification information of the moving image to be reproduced and the frame rate associated with the frame rate definition table 81 are acquired, and the acquired frame rate is determined. The moving image identification information of the moving image to be reproduced is the moving image identification information included in the reproduction instruction received in step S02 of FIG. 8 or when a predetermined state of the MFP 100 is detected in step S02. This is moving image identification information associated with a predetermined state by the state table 85 stored in the HDD 116. Then, the playback frame rate is changed to the determined frame rate (step S22).

  Next, a threshold value corresponding to the login user is set (step S23), and the process proceeds to step S24. A threshold value assigned in advance is set for each user identification information.

  Then, one of a plurality of frames included in the moving image 83 to be reproduced is selected (step S24). The moving image to be reproduced is the moving image 83 specified by the moving image identification information included in the reproduction instruction received in step S02 of FIG. 2, or when a predetermined state of the MFP 100 is detected in step S02. , The moving image 83 specified by the moving image identification information associated with a predetermined state by the state table 85 stored in the HDD 116. A plurality of frames included in the moving image 83 to be reproduced are selected in order from the beginning. Then, it is determined whether or not the priority assigned to the selected frame is greater than or equal to the threshold set in step S23. If it is equal to or greater than the threshold value, the process proceeds to step S26; otherwise, step S26 is skipped and the process proceeds to step S27. In step S26, the frame selected in step S24 is reproduced at the frame rate changed in step S22. That is, when step S26 is skipped, the frame selected in step S24 is not reproduced but thinned out. For this reason, the number of frames can be reduced. Further, since the frame to be thinned out is a frame with a low priority, the content of the moving image is not impaired. Furthermore, since a threshold corresponding to the skill level of the logged-in user is set, only the minimum necessary part can be shown to the logged-in user. In addition, since the same image or an image with little change is thinned out, it is possible to display almost the same image as when the frame rate is not lowered.

  In step S27, it is determined whether or not the job being executed has ended. If the job is completed, the process proceeds to step S08 in FIG. 8, but if not, the process proceeds to step S28. In step S28, it is determined whether or not the reproduction of the moving image has ended. In step S24, it is determined whether or not the last frame among a plurality of frames included in the moving image 83 has been selected. If the reproduction of the moving image is completed, the process returns to the moving image reproduction process. If not, the process returns to step S24.

<Modification>
The MFP 100 according to the above-described embodiment performs processing for reproducing a moving image and processing for executing a job in parallel. The MFP 100 according to the modification is configured to execute a process of reproducing a moving image with priority as much as possible. Hereinafter, differences from MFP 100 in the above-described embodiment will be described.

  FIG. 10 is a functional block diagram illustrating an example of functions of the CPU included in the MFP according to the modification, together with data stored in the HDD. Referring to FIG. 10, the difference from the functional block diagram shown in FIG. 4 is that permission accepting unit 55 is deleted, reproducing unit 59A is changed, and double speed reproducing unit 67 is added, comparing unit 77. Is added, and the process execution unit 73A is changed to include a stop unit 75.

  The comparison unit 77 compares the processing priority given to the processing executed by the processing execution unit 73 and the moving image priority given to the moving image reproduced by the reproduction unit 59. The processing priority is received together with the job when the job is received. The moving image priority is a value set in advance for each of the plurality of moving images 83 stored in the HDD 116. In the present embodiment, a priority definition table 87 that associates moving image identification information and moving image priority is stored in HDD 116 in advance.

  FIG. 11 is a diagram illustrating an example of a job setting screen. The job setting screen is a screen displayed when the printer driver program is executed in the PCs 200, 200A, and 200B and a job is set. Referring to FIG. 11, the job setting screen includes an area for setting the job priority on the right side where “priority” is displayed. Here, the job priority has 5 levels from 1 to 5, and the higher the number, the higher the level. That is, the job priority is a value set by a user who inputs a job.

  FIG. 12 is a diagram illustrating an example of a moving image priority definition table. Referring to FIG. 12, the moving image priority definition table includes a moving image identification information item, a type item, a content item, and a moving image priority item. In the moving image identification information item, moving image identification information for identifying a moving image is set. In the type item, a classification name of a moving image into which the moving image is classified is set. Here, the classification name is classified as a jam processing system in which a moving image relating to an operation at the time of paper jam is classified, an exchanging person in which a moving image relating to an operation for replacing consumables is classified, and a moving image relating to an operation for setting a job There are three lecture systems. In the content item, text for explaining the content of the moving image is set. In the moving picture priority item, a priority given to a moving image is set.

  Returning to FIG. 10, the comparison unit 77 receives the processing priority given to the processing executed by the processing execution unit 73 together with the job, and defines the priority of the moving image given to the moving image reproduced by the reproduction unit 59. Get by referring to the table. The comparison unit 77 compares the processing priority with the moving image priority and determines whether the moving image priority exceeds the processing priority. When the moving image priority exceeds the processing priority, an instruction to give priority to the reproduction of the moving image is output to the process execution unit 73A and the reproduction unit 59A. In addition, even if the moving image priority does not exceed the processing priority, the comparing unit 77 determines that the moving image is not reproduced if the remaining reproduction time of the moving image reproduced by the reproducing unit 59 is shorter than a predetermined value. An instruction to give priority to playback is output.

  When the stop unit 75 included in the process execution unit 73A receives an instruction from the comparison unit 77 to prioritize the reproduction of moving images, the stop unit 75 executes the processes until the reproduction of the moving images reproduced by the reproduction unit 59 is completed. To stop. For this reason, it is possible to cause the CPU 111 to execute only the process of reproducing a moving image, and it is possible to reproduce all of a plurality of frames included in the moving image. When the instruction to prioritize the reproduction of moving images is not input from the comparison unit 77, in other words, the processing execution unit 73 is a case where the moving image priority does not exceed the processing priority, and is reproduced by the reproduction unit 59. If the remaining playback time of the moving image is greater than or equal to a predetermined value, processing is executed.

  When the instruction to prioritize the reproduction of the moving image is input from the comparison unit 77, the reproduction unit 59 activates the double speed reproduction unit 67 without activating the slow reproduction unit 61. The double speed reproduction unit 67 reproduces a moving image by increasing the frame rate. For example, the rate of increasing the frame rate can be arbitrarily determined. When a moving image is reproduced at an increased frame rate, the reproduction time is shortened. For example, if the frame rate is doubled, the playback time is halved. For this reason, the reproduction of the moving image can be terminated at an early stage, and the time during which the process execution unit 73 stops the process can be shortened. In addition, when frames are thinned out by the thinning unit 63, the time for reproducing a moving image is not further shortened.

  The playback unit 59 activates the slow playback unit 61 without activating the double speed playback unit 67 when the instruction to prioritize playback of moving images is not input from the comparison unit 77. In this case, the processing is executed by the processing execution unit 73 and the moving image is reproduced by the slow reproduction unit 61 with a reduced frame rate. This case is the same as the embodiment described above.

  FIG. 13 is a flowchart illustrating an example of the flow of a moving image reproduction process in the modification. The moving image reproduction process in the modified example is a process executed by the CPU 111 when the CPU 111 provided in the MFP 100 in the modified example executes the moving image reproduction program. Referring to FIG. 13, the difference from the moving image reproduction process shown in FIG. 8 is that steps S41 to S49 are executed instead of steps S12, S13 and S15. Since other processes are the same as those shown in FIG. 8, the description thereof will not be repeated here.

  In step S41, the processing priority is acquired. Since the processing priority is accepted together with the job accepted in step S05 and step S09, the processing priority is acquired. In step S42, the moving image priority is acquired. When the moving image identification information included in the reproduction instruction received in step S02 or the predetermined state of the MFP 100 is detected in step S02, the state table 85 stored in the HDD 116 is associated with the predetermined state. The moving image identification information and the moving image priority associated with the priority definition table are acquired. Then, it is determined whether the moving image priority exceeds the processing priority (step S43). If the moving image priority exceeds the processing priority (YES in step S43), the process proceeds to step S45. If not, the process proceeds to step S44. In step S44, it is determined whether or not the remaining reproduction time of the moving image that has been reproduced in step S08 is equal to or less than a threshold value T. If the remaining reproduction time is equal to or less than threshold value T, the process proceeds to step S47; otherwise, the process proceeds to step S14.

  If the moving image priority does not exceed the processing priority, and the remaining reproduction time of the moving image being reproduced is greater than the threshold value T, in step S14, the process of reproducing the moving image and the job A parallel reproduction process is executed in which the process defined by is executed in a time-sharing manner.

  In step S45, it is determined whether or not a moving image is being reproduced. If a moving image is being reproduced, the process proceeds to step S46, and if not, the process proceeds to step S46. In step S46, the moving image is normally reproduced, and the process proceeds to step S47. Specifically, in accordance with the reproduction instruction received in step S02, the moving image 83 specified by the moving image identification information included in the reproduction instruction is read from the HDD and is normally reproduced. If a predetermined state of MFP 100 is detected in step S02, moving image 83 specified by the moving image identification information associated with the predetermined state is read from HDD by state table 85 stored in HDD 116. Play normally.

  The case where the process proceeds to step S47 while the moving image is being reproduced is a case where normal reproduction is started in step S08. In step S47, the process started in step S06 or step S10 is temporarily stopped.

  In step S48, the process waits until the reproduction of the moving image started in step S08 or step S46 is completed (NO in step S48). When the reproduction of the moving image is completed (YES in step S48), the process proceeds to step S49. Proceed to In step S49, the process suspended in step S47 is resumed, and the process proceeds to step S16. When the moving image priority exceeds the processing priority, the processing is temporarily stopped, and the processing for reproducing the moving image is executed with priority. Even if the video priority does not exceed the processing priority, if the remaining playback time of the moving image being played is equal to or less than the threshold value T, the processing is paused and the moving image is played back with priority. However, if the threshold is shortened to make the period shorter, the influence on the user who instructs the execution of the process is reduced.

  As described above, MFP 100 according to the present embodiment reproduces a moving image with a reduced frame rate while a process different from the reproduction of the moving image is being performed, which increases the load on CPU 111. It is possible to prevent a moving image from being reproduced by skipping frames.

  In addition, since the moving image is played back at a frame rate corresponding to the processing being executed among the plurality of types of processing, the playback speed of the moving image can be varied according to the load on the CPU 111.

  In addition, since a frame having a frame priority of a predetermined value or less among a plurality of frames included in the moving image is thinned out, the reproduction time of the moving image can be shortened.

  Furthermore, since the frames to be thinned out differ depending on the authenticated user, the moving images to be reproduced can be made different between skilled users and those who are not.

  Further, when a predetermined state of the MFP such as a state where the front cover of the MFP 100 is opened or a paper jam is detected, a moving image associated with the detected state is automatically reproduced, so that the user's Operation can be simplified.

  Further, the MFP 100 executes the process when the moving image priority of the moving image 83 selected from the plurality of moving images 83 exceeds the processing priority of the process executed separately from the reproduction of the moving image. To stop. For this reason, since the execution of the process is stopped, it is possible to prevent the moving image from skipping frames.

  In addition, while the execution of the process is stopped, the moving image is played back at an increased frame rate. Therefore, the playback time of the moving image can be shortened to shorten the time during which the execution of the process is stopped. .

  Also, while the execution of the process is stopped, frames with a frame priority of a predetermined value or less are thinned out of a plurality of frames included in the moving image, so that the number of frames to be reproduced is reduced. Playback time can be shortened. For this reason, the time during which the execution of the process is stopped can be shortened.

  Further, even if the moving image priority does not exceed the processing priority, if the remaining reproduction time of the moving image to be reproduced is equal to or less than a predetermined time, the execution of the process is stopped until the reproduction of the moving image is completed. A user who browses a moving image can browse the moving image without skipping frames to the end.

  Further, when the MFP 100 is reproducing a moving image selected from the plurality of moving images, the MFP 100 detects the predetermined state of the MFP 100 and detects the device detected from the plurality of moving images. A moving image associated with a state in advance is reproduced. For this reason, a moving image corresponding to a predetermined state of MFP 100 is automatically reproduced, so that the operation by the user can be facilitated.

  In the above-described embodiment, the MFP 100 has been described as an example of the moving image reproducing apparatus. However, the moving image reproducing method and the moving image reproducing method for executing the moving image reproducing process illustrated in FIGS. It goes without saying that the invention can be understood as a moving image reproduction program to be executed by a computer.
