Description

  The present invention relates to a technique for controlling an image processing apparatus.

  As an image processing device such as an MFP (Multi Function Peripheral, Multi Function Printer), a common interface (Web API) that can use the functions of the image processing device to a terminal device such as an external PC (Personal Computer) is provided. There is something.

  On the other hand, as an image processing apparatus, it is considered that a part for performing screen display or key input operation is made independent from the main body as an operation unit so that the operation response is not lowered even when the load on the main body is high. The operating unit is equipped with an independent OS (Operating System) such as Android OS and operates independently of the main unit.

  In this case, it is efficient that the operation unit uses the function of the main body through the above-described common interface.

  As described above, in the image processing apparatus separated into the main unit and the operation unit, it is efficient to use the function of the main unit from the operation unit through the common interface provided by the main unit. The same processing is performed for the same request, and there is a problem that the processing cannot be changed according to the characteristics of the terminal device such as an external PC and the operation unit.

  For example, external terminal devices are connected to the main unit via a network such as the Internet, whereas the operation unit is often connected to the main unit via a dedicated line, so the amount of data that can be transmitted and received is also different. There is. In addition, users of external terminal devices are often operated away from the image processing device, whereas users of the operation unit are operating in front of the image processing device and ask the user for some measures. Or the meaning of providing some information to the user is different.

  Although it is conceivable that a common interface is provided separately for the external terminal device and the operation unit, the significance of the common interface is diminished in the first place, and the common interface needs to be significantly modified, and the burden of subsequent maintenance also increases. .

  On the other hand, Patent Document 1 discloses a method of measuring a distance between two time points when an instruction is given from a mobile terminal to an image processing apparatus, and switching processing according to the distance. For example, when printing instructions are being approached, there is a high possibility that paper will be picked up, so processing such as outputting printed matter is performed.

  However, Patent Document 1 is not intended for an image processing apparatus in which a main body and an operation unit are independent, and cannot solve the above-described problems.

  The present invention has been proposed in view of the above-described conventional problems, and the object of the present invention is to determine whether a request source is a specific device even if it is a request for a common interface. Thus, it is possible to perform appropriate processing in accordance with the characteristics of the request source.

To solve the above problems, in the present invention, the application or the image processing device operating in the interior of the device interfaces according to internal Web API provided in the image processing apparatus of the image processing apparatus external terminal device A specifying unit that specifies whether a request source of the processing request is an internal device included in the image processing apparatus or a terminal device external to the image processing apparatus when receiving a processing request from an application ; And processing means for executing the process by changing the processing content according to the requested source.

  In the present invention, even if the request is for the common interface, it is possible to perform appropriate processing according to the characteristics of the request source by determining whether the request source is a specific device.

  Note that the functions included in the main unit 2 or the operation unit 3 are not necessarily implemented in the main unit 2 or the operation unit 3, and may be realized as functions available on the network.

<Operation>
FIG. 4 is a sequence diagram illustrating a processing example of the above embodiment. FIG. 4A illustrates a case where the copy function of the main unit 2 is used from the operation unit application 312 of the operation unit 3 via the common interface 213. ) Is a case where the general application 61 of the terminal device 6 or the general application 81 of the terminal device 8 similarly uses the copy function of the main unit 2 via the common interface 213.

  4A, when the common interface 213 of the main body unit 2 is requested to acquire a scan and a preview image from the operation unit application 312 of the operation unit 3 (step S101), the common interface 213 sends a scan and preview image to the module 212. Acquisition is requested (step S102).

  The module 212 performs scanning after determining whether the request is for the operation unit 3 or the terminal devices 6 and 8 (step S103). Detailed processing at the time of scanning will be described later.

  When the module 212 determines that the operation unit 3 has requested it, the module 212 can transmit image data through a high-speed dedicated line via the cable 4, and high image quality is expected when the user is in front of the image processing apparatus 1. Therefore, the preview image is transmitted to the common interface 213 in a large size, high quality lossless format and a format that can be displayed at any time while being received (step S104). The common interface 213 transfers the preview image to the operation unit application 312 (step S105), and the operation unit application 312 displays the received preview image.

  Thereafter, when printing is requested from the operation unit application 312 to the common interface 213 (step S106), the common interface 213 requests printing to the module 212 (step S107).

  In FIG. 4B, when the common application 213 of the terminal device 6 or the general application 81 of the terminal device 8 requests the common interface 213 of the main body 2 to obtain a scan and a preview image (step S111), the common interface 213 is a module. 212 is requested to obtain a scan and a preview image (step S112).

  The module 212 performs scanning after determining whether the request is for the operation unit 3 or the terminal devices 6 and 8 (step S113). Detailed processing at the time of scanning will be described later.

  If the module 212 determines that the request is for the terminal devices 6 and 8, the image data cannot be transmitted through the high-speed dedicated line via the cable 4, and therefore a highly compressed preview image in a small lossy format is shared with the common interface. It transmits to 213 (step S114). The common interface 213 transfers the preview image to the operation unit application 312 (step S115), and the operation unit application 312 displays the received preview image.

  Thereafter, when printing is requested from the general applications 61 and 81 to the common interface 213 (step S116), the common interface 213 requests printing to the module 212 (step S117).

  FIG. 5 is a flowchart showing an example of processing during scanning (steps S103 and S113 in FIG. 4).

  In FIG. 5, the module 212 performs a scan (step S121), whether or not the request is from a predetermined IP address, that is, the IP address assigned to the operation unit 3, header information of the IP packet indicating the request, etc. (Step S122).

  If it is determined that the request is from a predetermined IP address (Yes in step S122), the image is converted into an image quality priority image in a lossless format (step S123).

  If it is determined that the request is not from a predetermined IP address (No in step S122), it is converted into a small size image in the lossy format (step S124).

  Then, the preview image is returned to the common interface 213 (step S125).

  FIG. 6 is a sequence diagram illustrating another processing example of the above embodiment. FIG. 6A illustrates a case where the printer function of the main unit 2 is used from the operation unit application 312 of the operation unit 3 via the common interface 213. (B) is a case where the printer function of the main unit 2 is similarly used from the general application 61 of the terminal device 6 or the general application 81 of the terminal device 8 via the common interface 213.

  In FIG. 6A, when the printing start is requested from the operation unit application 312 of the operation unit 3 to the common interface 213 of the main body unit 2 (step S201), the common interface 213 requests the module 212 to start printing (step S202). .

  The module 212 starts printing (step S203), but upon receiving an out-of-paper error notification from the main body system in the middle of printing (step S204), the terminal determines whether the original print request is the operation unit 3 or not. After determining whether the device is the device 6 or 8, the subsequent processing is changed. Detailed processing at the time of error notification will be described later.

  When the module 212 determines that the operation unit 3 has requested the user, the module 212 can estimate that the user is in front of the image processing apparatus 1, and can cause the user to replenish paper or use another size paper. Since it is better to cancel the error by a user operation such as changing it and complete printing correctly, printing is stopped (step S205).

  Then, the module 212 notifies the common interface 213 of a paper out error (Step S206), and the common interface 213 notifies the operation unit application 312 of the paper out error (Step S207).

  In FIG. 6B, when the general application 61 of the terminal device 6 or the general application 81 of the terminal device 8 requests the common interface 213 of the main body 2 to start printing (step S211), the common interface 213 starts printing to the module 212. Is requested (step S212).

  The module 212 starts printing (step S213), but upon receiving an error notification of out of paper from the main body system in the middle of printing (step S214), the terminal determines whether the original print request is the operation unit 3 or not. After determining whether the device is the device 6 or 8, the subsequent processing is changed. Detailed processing at the time of error notification will be described later.

  If the module 212 determines that the request is for the terminal device 6 or 8, the module 212 can estimate that the user is away from the image processing apparatus 1, cause the user to replenish paper, Since it is difficult to make a response such as changing to a size paper, forced printing is continued by automatic continuation processing (step S215). The automatic continuation processing is, for example, forcibly printing if the printing can be forcibly continued by changing the conditions, and canceling the print job if the printing is impossible.

  When the forced printing is completed, the module 212 notifies the common interface 213 of the completion of forced printing (step S216), and the common interface 213 notifies the operation unit application 312 of the completion of forced printing (step S217).

  FIG. 7 is a flowchart showing a processing example at the time of error notification (steps S204 to S206 and S214 to S216 in FIG. 6).

  In FIG. 7, when the module 212 detects an error by error notification (step S <b> 221), a request is made as to whether or not the original print processing is a request from a predetermined IP address, that is, an IP address assigned to the operation unit 3. (Step S222).

  If it is determined that the request is from a predetermined IP address (Yes in step S222), printing is stopped (step S223), and an error is notified to the common interface 213 (step S223).

  When it is determined that the request is not from a predetermined IP address (No in step S222), automatic continuation processing is performed (step S225), and the automatic continuation processing result is notified to the common interface 213 (step S226).

  FIG. 8 is a sequence diagram illustrating still another processing example of the embodiment. FIG. 8A illustrates a case where the printer function of the main body unit 2 is used from the operation unit application 312 # 2 of the operation unit 3 via the common interface 213. Control of the signage application (operation unit application 312 # 3) in FIG. 5, (b) also uses the printer function of the main unit 2 from the general application 61 of the terminal device 6 or the general application 81 of the terminal device 8 via the common interface 213. This is the control of the signage app (operation unit app 312 # 3) when

  In FIG. 8A, when the printing start is requested from the operation unit application 312 # 2 of the operation unit 3 to the common interface 213 of the main body unit 2 (step S301), the common interface 213 requests the module 212 to start printing (step S301). S302).

  The module 212 starts printing (step S303). After determining whether the operation unit 3 or the terminal device 6 or 8 has requested printing, the module 212 is an operation unit application 312 # that is a signage application. 3 is changed to determine whether or not to make a startup request.

  The module 212 can estimate that the user is in front of the image processing apparatus 1 when determining that the request is the operation unit 3, and is considered to have an advertising effect when an advertisement is displayed on the operation unit 3. Therefore, after starting printing, an activation request is issued to the operation unit application 312 # 3, which is a signage application (step S304). In response to this, the operation unit application 312 # 3 displays an advertisement on the liquid crystal touch panel 33 of the operation unit 3.

  When printing is completed, the module 212 notifies the common interface 213 of the completion of printing (step S305), and the common interface 213 notifies the operation unit application 312 # 2 of the completion of printing (step S306).

  In FIG. 8B, when the general application 61 of the terminal device 6 or the general application 81 of the terminal device 8 requests the common interface 213 of the main unit 2 to start printing (step S311), the common interface 213 starts printing to the module 212. Is requested (step S312).

  The module 212 starts printing (step S313). After determining whether the operation unit 3 or the terminal device 6 or 8 has requested printing, the module 212 is an operation unit application 312 # that is a signage application. 3 is changed to determine whether or not to make a startup request.

  When the module 212 determines that the request is for the terminal devices 6 and 8, the user is not in front of the image processing apparatus 1 and thus does not look at the operation unit 3, or a different user uses the operation unit 3. Since there is no advertising effect when an advertisement is displayed on the operation unit 3, no activation request is issued to the operation unit application 312 # 3, which is a signage application, after the start of printing.

  When printing is completed, the module 212 notifies the common interface 213 of the completion of printing (step S314), and the common interface 213 notifies the operation unit application 312 # 2 of the completion of printing (step S315).

  FIG. 9 is a flowchart showing an example of processing at the start of printing (steps S303 and S313 in FIG. 8).

  In FIG. 9, when the module 212 starts printing (step S321), whether or not the printing process is a request from a predetermined IP address, that is, an IP address assigned to the operation unit 3, is indicated in the IP packet indicating the request. Judgment is made from the header information or the like (step S322).

  If it is determined that the request is from a predetermined IP address (Yes in step S322), an activation request is made to the signage application (step S323).

  When it is determined that the request is not from a predetermined IP address (No in step S322), no activation request is made to the signage application.

  Thereafter, when printing is completed (step S324), the common interface 213 is notified of printing completion (step S325).
