Description

  The present invention relates to a recording system in which an imaging apparatus such as a digital camera and a recording apparatus such as a printer are connected, and more particularly to a photo direct printing technique.

  In recent years, digital cameras (imaging devices), so-called digital cameras, which can take an image with a simple operation and convert it into digital image data have been widely used. When printing an image taken with such a digital camera and using it as a photograph, the taken digital image data was once taken into a personal computer (hereinafter referred to as PC) from the digital camera, and image processing was performed on the PC. After that, it is common to enjoy photos by outputting from the PC to a printer.

  On the other hand, recently, a color print system that directly transmits digital image data from a digital camera to a color printer or the like without using a PC and a memory card mounted on the digital camera are directly attached to the color printer, A so-called photo direct (PD) printer that can print a captured image stored in the memory card has also been developed.

In particular, when printing image data directly from a digital camera to a printer, the digital camera has different specifications, functions, and operation methods for each manufacturer. However, it is necessary to provide a system and a printer that can receive and print image data from image pickup apparatuses of various companies by performing image data transfer and printing instructions independent of the interface.

Reference numeral 3004 denotes a printer engine. Here, a printer engine of an ink jet printer that prints a color image using a plurality of color inks is installed. Reference numeral 3005 denotes a USB bus connector as a port for connecting a digital camera (DSC) 3012. Reference numeral 3006 denotes a connector for connecting the viewer 1011. Reference numeral 3008 denotes a USB bus hub (USB HUB). When the printer 1000 prints image data transferred from the PC 3010, the data from the PC 3010 is directly passed through and output to the printer engine 3004 via the USB bus 3021. . As a result, the connected PC 3010 can directly perform printing by exchanging data and signals with the printer engine 3004 (functions as a general PC printer). Reference numeral 3009 denotes a power connector which inputs a DC voltage converted from commercial AC by a power source 3013. A PC 3010 is a general personal computer, 3011 is the memory card (PC card) described above, and 3012 is a digital camera. Note that the exchange of signals between the control unit 3000 and the printer engine 3004 is performed via the USB bus 3021 or the IEEE 1284 bus 3022 described above.

  FIG. 4 is a block diagram showing the configuration of the ASIC 3001. In this figure as well, portions common to the above-mentioned drawings are given the same reference numerals and explanations thereof are omitted.

  Reference numeral 4001 denotes a PC card interface unit that reads image data stored in the attached PC card 3011 or writes data to the PC card 3011. Reference numeral 4002 denotes an IEEE 1284 interface unit that exchanges data with the printer engine 3004. The IEEE 1284 interface unit 4002 is a bus used when printing image data stored in the digital camera 3012 or the PC card 3011. A USB interface unit 4003 exchanges data with the PC 3010.

As a result, the DSP 3002 can detect whether the PC card 3011 is inserted or removed. When the PC card 3011 is inserted, compressed image data (for example, a JPEG image) stored in the PC card 3011 is read and stored in the memory 3003. Next, when printing of the stored image data is instructed using the operation panel 1010, the compressed image data is expanded and stored in the memory 3003, converted from Ycc or RGB signals to YMCK signals, and output γ. Printing is performed by executing correction, error diffusion, dithering, etc., and converting the print data into printable data that can be printed by the printer engine 3004, and outputting it to the printer engine 3004 via the IEEE1284 interface unit 4002.
<Camera / printer connection>
FIG. 5 is a diagram for explaining the outline of the connection between the PD printer 1000 and the DSC 3012 according to the first embodiment, and the same reference numerals are given to the portions common to the above-mentioned drawings, and the description will be omitted.

  In the figure, the cable 5000 includes a connector 5001 connected to the connector 1012 of the PD printer 1000 and a connector 5002 connected to the connection connector 5003 of the digital camera 3012. The digital camera 3012 is configured to be able to output image data stored in an internal memory via a connection connector 5003. Note that as the configuration of the digital camera 3012, various configurations such as a configuration having a memory as a storage unit inside and a configuration having a slot for mounting a removable memory can be employed. As shown in FIG. 5, by connecting the PD printer 1000 and the digital camera 3012 via the cable 5000, the image data from the digital camera 3012 can be directly printed by the PD printer 1000.

  Here, the operation when the digital camera 3012 is connected to the PD printer 1000 as shown in FIG. 5 will be described.

  When the above-described print determination keys 2007 and 2008 are not pressed, only the camera mark is displayed on the display unit 1006 of the operation panel 1010, the display and operation on the operation panel 1010 are invalid, and the viewer 1011 is displayed. The display is also invalidated. Accordingly, since only the key operation on the DSC 3012 and the image display on the display unit (not shown) are valid after this, the user can specify printing using the DSC 3012. When the print determination key 2007 or 2008 is pressed, a camera mark is displayed on the display unit 1006 of the operation panel 1010, and the display on the operation panel 1010 displays print settings corresponding to the print determination key.

  The first embodiment according to the present invention is intended to provide a PD printer capable of connecting and printing with digital cameras of a plurality of manufacturers. Therefore, the PD printer 1000 and DSC 3012 are connected and printed as follows. The communication protocol when performing the above will be described in detail.

  In the first embodiment, communication control between a PD printer and a digital camera is performed using a general-purpose file and a general-purpose format, and NCDP (New Camera Direct Print) independent of an interface is proposed.

  FIG. 6 is a diagram illustrating an example of an NCDP configuration.

  In the figure, 600 indicates an interface by USB, and 601 indicates an interface by Bluetooth. Reference numeral 602 denotes an application layer incorporated when a system based on NCDP is constructed. Reference numeral 603 denotes a layer for executing an existing protocol and interface. Here, PTP (Picture Transfer Protocol), SCSI and Bluetooth BIP (Basic Image Profile), USB interface, and the like are mounted. The NCDP according to the present embodiment is premised on that such an architecture such as a protocol layer is implemented and is implemented as an application thereon. Here, the PD printer 1000 is defined as a USB host and the camera 3012 is defined as a USB slave, and each has the same NCDP configuration as shown in FIG.

  FIG. 7 is a diagram for explaining the flow of communication procedures between the PD printer 1000 and the digital camera 3012 by NCDP according to the first embodiment.

  Here, as shown in FIG. 5, when it is detected that the PD printer 1000 and the DSC 3012 are connected by the USB cable 5000, communication between these devices becomes possible. As a result, the application installed in these devices is executed, and the transition to the procedure 701 by NCDP is started. Reference numeral 702 denotes an initial state of NCDP. Here, it is determined whether or not each model can execute NCDP, and if possible, the procedure proceeds to NCDP procedure 701. If the DSC 3012 does not implement NCDP, communication control by NCDP is not executed. After the transition to NCDP in this way, as indicated by reference numeral 703, when the DSC 3012 gives an instruction to transfer / print image data according to the “basic procedure”, the DSC 3012 transfers the image file to the PD printer 1000 and prints in the simple print mode. Transition.

  Further, as indicated by 704, when image data transfer / printing is instructed by the “recommended procedure” from the DSC 3012, various negotiations are performed between the DSC 3012 and the PD printer 1000 to determine the printing conditions and the like. The image file is transferred from the DSC 3012 to the PD printer 1000 to be printed, and the printing mode is shifted to a wider variety of printing modes.

  Reference numeral 705 denotes an “extended procedure”. When the DSC 3012 gives an instruction for this “extended procedure”, for example, printing is performed with an advanced layout function such as DPOF, XHTML-print, SVG, and the specifications unique to each vendor. The mode is set. Note that the detailed specification by the “expansion procedure” is defined in the extended specification for each DSC manufacturer, and will not be described here. Further, image printing by these “basic procedure” and “recommended procedure” will be described later with reference to FIGS.

  8A and 8B are diagrams for explaining commands defined for performing printing in NCDP according to the first embodiment. FIG. 8A shows a command table in NCDP, and FIG. 8B shows “SendStatus”. FIG. 4 is a diagram for explaining status components used in “SendSupportedStatus”.

  In FIG. 8A, the “corresponding mode” corresponds to the above-described “basic procedure”, “recommended procedure”, and “extended procedure” instructed from the DSC 3012. While all the commands can be used in the “recommended procedure”, the “basic procedure” is the simple print mode. Only the command to shift to each mode, the acquisition of image data from the DSC 3012, and the print command from the DSC 3012 can be used. In the “extended procedure”, it is described that only the command for shifting to each mode of transition to NCDP and its termination, “basic procedure”, “recommended procedure”, and “extended procedure” is used. Needless to say, other commands may be used according to the specifications of each company.

  In FIG. 8B, <Status> indicates <dpsPrintServiceStatus>, <Warning>, <Fatal>, <jobEndReason>, <disconnectEnable>, <capabilityChanged> described below. It is composed of <DpsPrintServiceStatus> indicates whether the PD printer 1000 is printing (Printing), idle (Idle), or printing is paused (Pause). <Warning> indicates that the PD printer 1000 is in a recoverable error state. <Fatal> indicates that the PD printer 1000 is in an unrecoverable error state. <JobEndReason> indicates the reason why the PD printer 1000 has finished printing, “notEnded” indicates that printing is in progress (printing has not ended), and “endedNormaly” indicates that printing has ended normally. “EndedByJobAbort” indicates that printing has been completed by <JobAbort> from the DSC 3012, and “endedByPrinterReason” indicates that printing has been completed by the termination processing of the PD printer 1000. <DisconnectEnable> is “True” indicating that the print job instructed by <JobStart> can be normally terminated even if the PD printer 1000 is disconnected from the physical connection with the DSC 3012, and “False” indicating that disconnection is impossible. Is included. <CapabilityChanged> includes “True” indicating that the Capability of the PD printer 1000 has been changed, and “False” indicating that the Capability has not changed. In addition, the DSC 3012 that has received this <capabilityChanged> is required to reacquire the Capability of the PD printer 1000 using the “getCapability” command.

  Hereinafter, image printing by the above-described “basic procedure” and “recommended procedure” will be described.

  FIG. 9 is a diagram for explaining an NCDP communication procedure when image printing is performed according to the “basic procedure”. This “basic procedure” is a simple print mode in which one image file is transferred from the DSC 3012 to the PD printer 1000 and printed, and the corresponding image format is, for example, VGA size (640 × 480). Pixel) RGB image, VGA size (640 × 480 pixels) JPEG image, and the image file size is about 1 Mbyte or less. The DSC 3012 transmits in an image format supported by the PD printer 1000. In this case, error handling is not executed.

  First, in 900, the PD printer 1000 transmits a command (NCDPStart) instructing the shift to NCDP to the DSC 3012. If the DSC 3012 is equipped with NCDP, OK is returned (901). A specific example of using PTP as an example of performing the NCDP confirmation procedure will be described in detail later with reference to FIG.

  If it is confirmed that the NCDP is installed in this way, a command (ProcedureStart) is transmitted from the PD printer 1000 to the NCDP mode to the DSC 3012 (902). On the other hand, when the “basic procedure” which is the simple print mode is sent from the DSC 3012 in 903, the process proceeds to the print mode based on the “basic procedure” thereafter. In this case, when an image to be printed is selected by an operation in the DSC 3012 and printing is instructed, a command (JobStart) instructing the start of printing is sent from the DSC 3012 to the PD printer 1000 (904). As a result, the PD printer 1000 enters the simple print mode, and sends a command (GetImage) to the DSC 3012 to request a JPEG image (905). As a result, a JPEG image is transmitted from the DSC 3012 to the PD printer 1000 (906), and printing processing in the PD printer 1000 is started. Thus, when the printing of the designated image is completed, a command (SendStatus) indicating the end of the print job is transmitted from the PD printer 1000 to the DSC 3012 (907). On the other hand, when an affirmative response (OK) is returned from the DSC 3012 (908), the printing process according to this "basic procedure" is completed. Whether or not to exchange in this “basic procedure” is also determined by the Capability of both the DSC 3012 and the PD printer 1000.

  FIG. 10 is a diagram for explaining the NCDP communication procedure when image printing is performed according to the “recommended procedure”. The same steps as those in FIG.

  In this “recommended procedure”, a “more various printing” mode based on negotiation between the PD printer 1000 and the DSC 3012 can be set, and a plurality of photo prints and layout prints can be performed. Also, error handling can be executed.

  In FIG. 10, after confirming that NCDP is installed in the same manner as in FIG. 9, in this case, a “recommended procedure” is instructed from the DSC 3012 (910). Thereafter, the procedure according to the “recommended procedure” is executed. In the recommended procedure 910, first, the DSC 3012 transmits all status information supported by the DSC 3012 to the PD printer 1000 by a command “SendSupportedStatus”. This Status information is transmitted to the PD printer 1000 in a script format (text). This Status information is composed of a plurality of pieces of information as shown in FIG. 8B, and each piece of information supported by the DSC 3012 is transmitted to the PD printer 1000. Then, the PD printer 1000 selects information to be transmitted by “SendStatus” based on the support information from the DSC 3012 informed by the “SendSupportedStatus”.

  Next, as indicated by 911, the PD printer 1000 notifies the DSC 3012 of all functions including the functions of the PD printer 1000 and functions including paper settings, etc., as Capability information in response to the “GetCapability” command from the DSC 3012. This Capability information is transmitted to the DSC 3012 in a script format (text).

  An example of this Capability information is shown in FIG.

  As shown in FIG. 12, this Capability information includes the type and size of printable paper, print quality, image data format, presence / absence of date printing, presence / absence of file name printing, layout, presence / absence of image correction, and partial printing. It includes information on the presence / absence, the position / size of the part, and optionally the presence / absence of functions corresponding to the specifications of each camera manufacturer.

  Thus, by making Capability information into script notation, it has been devised so that porting to other communication protocol architectures can be performed easily, and the exchange of such function information can be more easily standardized. Note that this script notation may be XML compliant.

  The user of the DSC 3012 that has received such Capability information determines what is to be used for printing from the functions of the PD printer 1000, selects an image to be printed, and sets the printing conditions for the image to the PD printer 1000. Select from the functions that have. When an image to be printed and printing conditions are determined in this way and a print start is instructed, a print command (JobStart) is sent to the PD printer 1000 (904). As a result, a command (GetImage xn) requesting the image data is issued from the PD printer 1000 (912), and in response, the corresponding image data is received from the DSC 3012 in an image format (Tiff, JPEG, RGB, etc.) are transmitted (913). Here, a plurality of pieces of image data can be transmitted for one image printing. For example, when layout printing such as 2 × 2 is designated, four sheets of data are printed on one sheet. This is because it is necessary to transmit the image data of the minute. Thus, when the printing of the designated image is completed, a command (JobEnd) indicating the end of the print job is transmitted from the PD printer 1000 to the DSC 3012 (907). On the other hand, when an affirmative response (OK) is returned from the DSC 3012 (908), the process proceeds to the next image selection / printing process according to the "recommended procedure" again.

  FIG. 11 is a diagram for explaining a communication procedure when an error occurs in the PD printer 1000 in the NCDP communication procedure when printing an image according to the “recommended procedure” described above, and is common to FIG. 10 described above. The same reference numerals are given to the procedures, and the description is omitted.

  In this example, a case where a paper feed error occurs in the PD printer 1000 during execution of the printing process in the “recommended procedure” is shown. In this case, in 914, status information (Status) indicating a paper feed error is transmitted from the PD printer 1000 to the DSC 3012. On the other hand, a command indicating whether to continue the printing process (JobContinue) or cancel (JobAbort) is transmitted to the PD printer 1000 based on the determination by the user of the DSC 3012 (915). As a result, the PD printer 1000 cancels the printing process, transmits a print job end notification (JobEnd), and cancels printing (907). When the continuation is instructed, the print processing is continued after the paper feed error is repaired.

  Next, the processing procedure described above will be described with reference to the flowchart of FIG.

  FIG. 13 is a flowchart for explaining the communication procedure shown in FIG.

  First, in step S1, communication between the digital camera (DSC) 3012 and the PD printer 1000 is established (700). In step S2, it is determined whether or not these devices have NCDP installed. Migrate to In step S3, a procedure instruction from the DSC 3012 is received, and the procedure proceeds to the instructed procedure. Here, when “basic procedure” is instructed, the process proceeds from step S4 to step S5, and print processing according to “basic procedure” is executed.

  When “recommended procedure” is instructed, the process proceeds from step S6 to step S7, and the printing process according to the “recommended procedure” described above is executed.

  Further, when an “extended procedure” is instructed, the process proceeds from step S8 to step S9, and print processing based on the “extended procedure” corresponding to each vendor is executed. In other cases, the process proceeds to step S10, and printing in a unique mode by the PD printer 1000 and DSC 3012 is executed.

Next, an example will be described in which various commands in the above-mentioned NCDP (FIG. 8) are realized using general-purpose PTP (PTP wrapper). In this embodiment, NCDP using PTP will be described. However, the present invention is not limited to this. For example, the direct print service API is provided on another interface or another class. May be implemented.
[NCDPStart]
FIG. 14 is a diagram illustrating an example in which a command (NCDPStart) for instructing the start of the NCDP procedure is realized using the PTP architecture.

  After the PD printer 1000 and DSC 3012 are physically connected, first, in 1400, “GetDeviceInfo” is transmitted from the PD printer 1000 to the DSC 3012, and the DSC 3012 is requested for information on the held object. The In response to this, the DSC 3012 transmits information about the object held in the DSC 3012 to the PD printer 1000 by “DeviceInfo Dataset”. Next, in 1402, DSC 3012 is assigned as a resource by “OpenSession”, a handle for assigning a handle to a data object as necessary, or a request for starting a procedure for performing special initialization is issued. When “OK” is returned, PTP communication is started.

  Next, in 1403, if all handles “GetObjectHandles” in script format are requested to the DSC 3012 (Storage ID: FFFFFF, Object Type: Script), all handles held in the DSC 3012 in response to this in 1404. The list “ObjectHandlesArray” is returned. Next, at 1405 and 1406, the PD printer 1000 requests and acquires information on the i-th object handle (GetObjectInfo (Handle i), ObjectInfo i Dataset, GetObject (Handle i), Object i Data). Here, if this object includes a keyword (for example, “mountain”) indicating the identification of the DSC 3012, next, in 1407, the PD printer 1000 is instructed to transmit object information (SendObjectInfo). When an affirmative response (OK) is received, object information is transmitted from the PD printer 1000 to the DSC 3012 by SendObject. Here, this object includes, for example, “river” as a response keyword (password) for the keyword.

In this way, both the PD printer 1000 and the DSC 3012 can recognize each other's connection partner, and thereafter, the procedure proceeds to the NCDP procedure (710 in FIG. 7). In this way, a keyword can be reliably transferred in a transport layer that can transfer a file. That is, keywords can be exchanged without adding a unique command or the like to the NCDP of the present embodiment. Here, the keyword is not limited to the above example, and the same keyword may be used. In addition, in order to shorten the time for performing the negotiation with this keyword, the time required for checking each other's devices can be shortened by placing this keyword at the beginning of the script handle.
[ProcedureStart]
FIG. 15 is a diagram for explaining an example in which a command (ProcedureStart) for receiving a command for instructing a mode transition procedure from the DSC 3012 is implemented using the PTP architecture.

  Here, first, in 1501, there is object information to be transmitted to the DSC 3012 by “SendObjectInfo” in order to notify the DSC 3012 of the “basic procedure”, “recommended procedure”, and “extended procedure” supported by the PD printer 1000. Tell them. In response to this, when an affirmative response (OK) is sent from the DSC 3012, the DSC 3012 is informed by 1502 that the object is to be transmitted by “SendObject”, and this PD printer 1000 supports the next “Object Data” of 1503. Send information about the procedure you are doing. Next, in 1504, the DSC 3012 notifies the PD printer 1000 that the GetObject operation is to be started (transfer to the push mode) by “RequestObjectTransfer”. As a result, when it is informed in 1505 that information related to object information is received from the PD printer 1000 (GetObjectInfo), the information is returned in 1506 by “ObjectInfo Dataset” (OK), and then in 1507 the object is returned. When the object information itself is requested by designating information, the procedure (“basic”, “recommended”, “extended”, etc.) used by the DSC 3012 is notified to the PD printer 1000 by “Object Dataset” (1508).

As a result, the image printing mode can be designated from the DSC 3012 to the PD printer 1000.
[NCDPEnd]
FIG. 16 is a diagram for explaining an example in which a command (NCDPEnd) for ending the communication procedure by NCDP is realized using the PTP architecture.

In this procedure, in 1600, the PD printer 1000 notifies the DSC 3012 that there is object information to be transmitted, and “Object Data” notifies the DSC 3012 that the NCDP mode is exited. On the other hand, when an affirmative response (OK) is received, “CloseSession” is transmitted at 1601 to end this communication. This completes the NCDP communication procedure.
[GetImage]
FIG. 17 is a diagram for explaining an example in which the communication procedure for obtaining image data (JPEG image) held by the DSC 3012 in the NCDP (GetImage) in the NCDP is realized using the PTP architecture.

First, in 1700, when the PD printer 1000 requests information related to the object held by the DSC 3012 (GetObjectInfo), in 1701, the information related to the object (ObjectInfo Dataset) is sent from the DSC 3012 to the PD printer 1000. Next, when the PD printer 1000 designates the object and issues an acquisition request (GetObject) in 1702, the requested image file (Object Dataset) is transmitted from the DSC 3012 to the PD printer 1000 in 1703. In this way, the PD printer 1000 can acquire a desired image file from the DSC 3012.
[SendStatus]
FIG. 18 is a diagram for explaining an example in which a communication procedure for notifying an error status or the like from the PD printer 1000 to the DSC 3012 in NCDP (SendStatus) is realized using the PTP architecture.

First, in 1800, the PD printer 1000 notifies the DSC 3012 that there is object information to be transmitted by “SendObjectInfo”. In 1801, an information set (ObjectInfo Dataset) related to the object information is transmitted to the DSC 3012. In response to an affirmative response (OK) from the DSC 3012, status information such as an error in the PD printer 1000 is “SendObject” and “Object Dataset”. Send by.
[GetCapability]
FIG. 19 is a diagram for explaining an example in which the communication procedure in the GetCapability command for notifying the function of the PD printer 1000 to the DSC 3012 in the NCDP according to the present embodiment is realized using the PTP architecture.

  Here, first, in 1901, the DSC 3012 informs the PD printer 1000 that the GetObject operation is to be started (transfer to the push mode) by “RequestObjectTransfer”. As a result, when it is notified in 1902 that information related to object information is received from the PD printer 1000 (GetObjectInfo), the information is returned in 1903 by “ObjectInfo Dataset”. Next, when the object information is specified in 1904 and the object information itself is requested from the PD printer 1000 (GetObject), the DSC 3012 notifies the PD printer 1000 of a Capability acquisition request by “Object Dataset” (1905). ). Next, in 1906, in order for the PD printer 1000 to notify the DSC 3012 of Capability, “SendObjectInfo” notifies that there is object information to be transmitted from the PD printer 1000 to the DSC 3012. On the other hand, when an affirmative response (OK) is sent from the DSC 3012, 1907 informs the DSC 3012 that the object is to be sent by “SendObject”. Next, in 1908 “Object Data”, the functions of the PD printer 1000 are transmitted to the DSC 3012 in the script format (FIG. 12).

In this way, the DSC 3012 can acquire Capability information of the PD printer 1000.
[JobStart]
FIG. 20 is a diagram for explaining an example in which a communication procedure for notifying the start of a print job (JobStart) from the DSC 3012 to the PD printer 1000 in the NCDP is realized using the PTP architecture.

First, in 2000, the DSC 3012 sends “RequestObjectTransfer” to the PD printer 1000 to prompt the PD printer 1000 to issue a “GetObjectInfo” command. As a result, when “GetObjectInfo” is issued from the PD printer 1000 in 2001, the DSC 3012 transmits information (ObjectInfo Dataset) relating to object information to be transmitted in 2002. On the other hand, when object information is requested from the PD printer 1000 in 2003 (GetObject), in 2004, the DSC 3012 transmits “Object Dataset” to the PD printer 1000 and issues a print command.
[JobAbort]
FIG. 21 is a diagram for explaining an example in which a communication procedure for issuing a print abort command from the DSC 3012 to the PD printer 1000 (JobAbort) in NCDP is realized using the PTP architecture.

In this case as well, as in FIG. 20, the DSC 3012 sends “RequestObjectTransfer” to the PD printer 1000 to prompt the PD printer 1000 to issue a “GetObjectInfo” command. Accordingly, when “GetObjectInfo” is issued from the PD printer 1000, the DSC 3012 transmits information (ObjectInfo Dataset) relating to object information to be transmitted. On the other hand, when object information is requested from the PD printer 1000 (GetObject), at 2101, the DSC 3012 transmits “Object Dataset” to the PD printer 1000 and issues a print cancel command.
[JobContinue]
FIG. 22 is a diagram illustrating an example in which a communication procedure for issuing a print resumption command from the DSC 3012 to the PD printer 1000 (JobContinue) in the NCDP according to the present embodiment is realized using the PTP architecture.

In this case as well, as in FIG. 20, the DSC 3012 sends “RequestObjectTransfer” to the PD printer 1000 to prompt the PD printer 1000 to issue a “GetObjectInfo” command. Accordingly, when “GetObjectInfo” is issued from the PD printer 1000, the DSC 3012 transmits information (ObjectInfo Dataset) relating to object information to be transmitted. On the other hand, when object information is requested from the PD printer 1000 (GetObject), at 2201, the DSC 3012 transmits “Object Dataset” to the PD printer 1000 and issues a print continuation command.
[SendSupportedStatus]
FIG. 23 shows a communication procedure in which the DSC 3012 notifies the presence or absence of support for each parameter described in (SendStatus) issued by the PD printer 1000 from the DSC 3012 to the PD printer 1000 in NCDP using the PTP architecture. It is a figure explaining the example implement | achieved.

  First, in 2300, the DSC 3012 sends “RequestObjectTransfer” to the PD printer 1000 to prompt the PD printer 1000 to issue a “GetObject” command. Accordingly, when “GetObjectInfo” is issued from the PD printer 1000 in 2301, the DSC 3012 transmits information (ObjectInfo Dataset) related to the object information to be transmitted in 2302. On the other hand, when object information is requested from the PD printer 1000 in 2303 (GetObject), “Object Dataset” is transmitted in 2304, and the PD printer 1000 issues the PD printer 1000 from the DSC 3012. Notify whether there is support for each parameter described in (SendStatus).

  Next, the Capability limitation processing procedure in the operation on the PD printer 1000, which is a characteristic part according to the present embodiment, and the processing in the PD printer 1000 and the DSC 3012 will be described.

  FIG. 24 is a flowchart for explaining processing in the DSC 3012 in the processing procedure of “recommended procedure”. A program for executing this processing is stored in the ROM 3101 and is executed under the control of the CPU 3100.

  First, in step S21, the DSC 3012 transmits Status information supported by the DSC 3012 to the PD printer 1000. Next, when Capability is received from the PD printer 1000 in step S22, the process proceeds to step S23, and the Capability is analyzed. If there are any matters that cannot be understood, ignore them. In step S24, a print setting instruction screen (UI) is displayed on the display unit 2700 of the DSC 3012. In step S25, the user inputs a print setting instruction by operating the operation button and switch 3103 based on the UI screen. When the print setting instruction is input in this way, the process proceeds to step S26, where a print job file describing the print target image file and various print conditions input and set using the UI screen is created. In step S27, the print job file is generated. The job file is transmitted to the PD printer 1000. In step S28, the image file described in the print job file is transmitted to the PD printer 1000.

  Here, since the DSC 3012 connected to the PD printer 1000 is based on the premise that an unspecified digital camera manufactured by each manufacturer is connected, conventionally, for example, the PD printer 30 from the PD printer 1000 to the DSC 3012 has its PD. All information held by the printer 1000 is transmitted to the DSC 3012 as Capability. For this reason, the DSC 3012 performs settings related to printing by allowing the user to select a Capability content that matches a function understandable by the DSC in the Capability analysis in Step S22 described above.

Next, when the print setting keys 2007 and 2008 are not pressed, that is, when settings relating to printing are performed according to the conventional example, and when the print setting keys 2007 and 2008 are pressed, the PD printer 1000 and the DSC 3012 Differences in Capability exchanged between them and differences in selection items displayed on the DSC will be described.
<When the print setting keys 2007 and 2008 are not pressed>
FIG. 30 is a diagram illustrating a sequence of printing operations when the above-described print setting keys 2007 and 2008 are not pressed in the “recommended procedure” according to the present embodiment.

  In the figure, by the exchange of 3001 and 3002, the Capability of the PD printer 1000 described in script is transmitted from the PD printer 1000 to the DSC 3012 as in steps S22 and S23 in FIG. The DSC 3012 receives and interprets this Capability, and ignores any matters that cannot be understood. Here, Capability sent from the PD printer 1000 to the DSC is shown in FIG. Even the PD printer in this embodiment communicates everything that can be handled as Capability to the digital camera. Specifically, there are three types of print quality, seven types of paper sizes, two types of paper, two types of image file formats, date printing support, file name printing support, and the like.

  Next, the DSC 3012 constructs a UI screen based on the interpreted Capability and displays it on the display unit (step S24 in FIG. 24). As a result, the UI screen on the DSC is as shown in FIG. In this figure, items shown on the left include paper size, paper type, layout, print quality, correction processing, and date printing. In addition, a plurality of selection items are shown for each item. Here, the items shown in bold indicate that the user can select (A4, 2L, L, etc.), and the gray characters are items that are not in the Capability of the printer, so the user selects them. This indicates that the item cannot be performed (postcard or the like), and further, the item enclosed by a square indicates that the item is currently selected (A4 or the like).

  While this UI screen is being displayed, an idle state indicated by 3003 in FIG. 30 is entered. In step S25 of FIG. 24, the user of the DSC 3012 designates an image file to be printed and printing conditions (paper type, paper size, image quality, etc.) using the displayed UI. As a result, a print job format file for designating a print job is created, and the print job file is transmitted from the DSC 3012 to the PD printer 1000 in 3004.

  Upon receiving this print job file, the PD printer 1000 analyzes the contents described in the print job file. In step 3005, the image file transmitted from the DSC 3012 is received. The PD printer 1000 decodes the received image file and develops it into image data, thereby printing under the printing conditions specified in the print job file. When printing is finished in this way, in 3006, the DSC 3012 is notified that the print job is finished.

When a series of printing is completed in this way, an idle state indicated by 3003 in FIG. 30 is entered. In this idle state, the PD printer 1000 waits for a print job, while the DSC 3012 waits for a user operation, and a series of printing operations ends.
<When the print setting keys 2007 and 2008 are pressed>
Next, a sequence of printing operations when the above-described print setting keys 2007 and 2008 in the “recommended procedure” according to the present embodiment are pressed will be described with reference to FIG.

  Similar to the above description, by the exchange of 3001 and 3002, the Capability of the PD printer 1000 described in script is transmitted from the PD printer 1000 to the DSC 3012 as in steps S22 and S23 in FIG. 24 described above, and the idle state (3003) It becomes. In this idle state (3003), for example, when the print setting key 2008 is pressed, the PD printer 1000 uses the “SendStatus (capabilityChanged = True)” command to notify the DSC 3012 that the Capability of the PD printer 1000 has been changed. (3004). Here, the DSC 3012 issues a “GetCapability” command to the PD printer 1000 to request a new Capability from the PD printer 1000 (3001). As a result, the latest Capability in the PD printer 1000 is transmitted from the PD printer 1000 to the DSC 3012 (3002).

  In this case, Capability sent from the PD printer 1000 to the digital camera is shown in FIG. Here, a description will be given assuming that the print setting key 2008 is pressed. This print setting key is a size (a size called an L version or a service version) of an image taken with a digital camera that is widely used in the silver halide photography industry. ) Is used to print on a medium of one image per special medium. For this reason, the PD printer according to the present embodiment transmits only limited items without communicating everything that can be handled as Capability to the digital camera. Specifically, one type of print quality, one type of paper size, one type of paper type, one type of image file format, and the like.

  Next, the DSC 3012 reconstructs the UI screen based on the interpreted Capability, and displays it on the display unit, in the same manner as the Capability reception and interpretation procedure.

  As a result, the UI screen on the DSC is as shown in FIG. 29. Items shown in bold indicate that the user can select them as in FIG. 27, and gray characters are items that are not in the Capability of the printer. Since it is a (restricted item), the user cannot select it. That is, the user can execute printing without making settings related to the printing process.

  Of course, since it is not necessary to display items that cannot be set on the user interface on the DSC side, it goes without saying that they may not be displayed at all, instead of being grayed out as shown in FIG. Further, since setting cannot be performed for all items, the UI screen regarding this printing may not be displayed.

On the other hand, when 3002 in FIG. 31 receives the latest Capability, the DSC 3012 is in a state where it can transmit a “JobStart” command in accordance with the Capability of the PD printer 1000 (idle state 3003 in FIG. 31). The idle state 3003 in FIG. 31 is the same as the idle state in FIG. After the mutual Capabilities are confirmed in this way, the PD printer 1000 that has received a print job in the idle state performs the same print operation as described above.
[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. 32 and 33. FIG.

  In the second embodiment, an item “setting by the PD printer” is added to each item of Capability shown in FIG. 26 and FIG. 28 of the first embodiment.

  FIG. 32 collectively shows all Capability items of the PD printer in the second embodiment, and an item “Printer” is added to each item in the first embodiment. “Printer” means that each item is set on the printer side. Therefore, on the UI screen of the DSC 3012 when the above-described print setting key 2008 is not pressed, as shown in FIG. 34, the display “Printer” meaning that each item shown in FIG. 27 is set on the printer side is displayed. It will be added.

  In addition, when the print setting key 2008 is pressed, the same exchange as the exchange between the DSC and the printer in the first embodiment is performed, and the information expressed in the script as the Capability of the PD printer 1000 from the PD printer 1000 to the DSC 3012. Is sent.

  Here, Capability sent from the PD printer 1000 to the DSC 3012 is shown in FIG. As shown in this figure, when the print setting key 2007 or 2008 of the PD printer 1000 is pressed, the print quality, paper size, paper type, date printing, layout, and correction processing items are all set only on the PD printer side. Capability. As with the first embodiment, this key is an image taken with a digital camera, one image per image using a special medium of a size (L version, called service version) that is prevalent in the silver halide photography industry. It is assumed that the usage form is to print on the medium. For this reason, the PD printer in this embodiment transmits only items that are set on the PD printer side without communicating everything that can be handled as Capability to the digital camera.

  Next, the DSC 3012 reconstructs the UI screen based on the interpreted Capability and displays it on the display unit in the same manner as the Capability reception and interpretation procedure. As a result, the UI screen on the DSC 3012 becomes as shown in FIG. Here, as in FIG. 27 and FIG. 28, gray characters indicate items that are not included in the Capability of the printer and cannot be selected by the user. That is, the user can execute printing without making settings related to the printing process.

  Of course, since it is not necessary to display items that cannot be set on the user interface on the DSC side, it goes without saying that they may not be displayed at all, instead of being grayed out as shown in FIG. Further, since setting cannot be performed for all items, the setting screen relating to printing may not be displayed.

On the other hand, upon receiving the latest Capability, the DSC 3012 enters a state where it can transmit a “JobStart” command in accordance with the Capability of the PD printer 1000 (idle state 3003 in FIG. 31). The idle state 3003 in FIG. 31 is the same as the idle state in FIG. After the mutual Capabilities are confirmed in this way, the PD printer 1000 that has received a print job in the idle state performs the same print operation as described above.
[Other Embodiments]
Even if the DSC 3012 does not support “capabilityChanged”, the means for causing the PD printer 1000 to acquire the Capability by the DSC 3012 by performing USB disconnection at 3004 in FIG. For example, as described above, NCDPEnd is executed, and then NCDPStart is executed. It can also be realized by executing PTP closeSession and then executing openSession.

  In this embodiment, the PD printer 1000 checks the notification function supported by the DSC 3012 and performs processing corresponding to the notification function. However, the present invention is not limited to this, and the DSC 3012 supports the PD printer 1000. Of course, it is possible to check the notification function being performed and execute processing corresponding to the notification function.

  Note that the present invention can be applied to a system (for example, a copier, a facsimile machine, etc.) consisting of a single device even when applied to a system composed of a plurality of devices (for example, a host computer, interface device, reader, printer, etc.). You may apply.

  In addition, an object of the present invention is to provide a storage medium (or recording medium) that records a program code of software that realizes the functions of the above-described embodiments (processing performed on the camera side, various printing processes performed on the printer side), This can also be achieved by supplying to a system or apparatus and reading and executing the program code stored in the storage medium by the computer (or CPU or MPU) of the system or apparatus. In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the storage medium storing the program code constitutes the present invention. Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also an operating system (OS) running on the computer based on the instruction of the program code. A case where part or all of the actual processing is performed and the functions of the above-described embodiments are realized by the processing is also included.

  Furthermore, after the program code read from the storage medium is written into a memory provided in a function expansion card inserted into the computer or a function expansion unit connected to the computer, the function is determined based on the instruction of the program code. The case where the CPU of the expansion card or the function expansion unit performs part or all of the actual processing and the functions of the above-described embodiments are realized by the processing is also included.

  As described above, according to the present embodiment, the PD printer is set as the USB host and the DSC is set as the slave, and the information regarding the Capability that the PD printer has before entering the printing operation is transmitted to the DSC. The DSC side can determine the optimum print mode based on the Capability information and perform printing.

  In addition, by transmitting this Capability information in script notation, porting to other communication protocols is facilitated and standardization is facilitated.

  In addition, the communication procedure between devices is performed using a general-purpose file or a general-purpose format, and by defining the communication procedure layer of the application according to the present embodiment in the upper layer, the communication procedure independent of various interface specifications is specified. can do.
