Description

  The present invention relates to an information processing apparatus, a method thereof, and a program.

  In a printing system using a computer equipped with an operating system (OS) such as Windows (registered trademark), an application program (hereinafter referred to as an application) is executed. The print data generated by executing such an application is stored in a spool file in a data format normally used by the OS. When the printing process is executed by the application and the generated print data is stored in the spool file, the normal OS calls the printer driver to print the print data. The called printer driver reads the print data stored in the spool file, creates an image by the image generation unit of the printer driver, and converts it into a print command that can be interpreted by the printer. The print command generated by the conversion is transmitted to the printer, interpreted by the printer, and the printing process is executed by forming an image on a recording medium, for example. Conventionally, in order to display an actual print mode as a preview in such a printing system, the printer driver executes a print process and activates a previewer that displays a print image. Such a preview display is generally realized by an image generation unit creating display image data for print preview, and passing the created image data to a previewer for display.

  In recent years, not the conventional EMF format (Enhanced Meta File) but the XPS format (XML Paper Specification) has been used as the data format stored in the spool file. In such a printing system, an XPS printer driver capable of handling XPS format data is also used as the printer driver. Since the XPS format is an open standard electronic document format developed by Microsoft Corporation, a display function is provided so that print data can be displayed as it is passed to the OS. When providing a print preview function in such a printing system, it is possible to display the XPS data, which is print data, without converting it to display image data by using a display function by the OS (for example, Patent Document 1).

  Furthermore, it is possible to add a print setting changing function to the print preview function so that the print setting can be changed while checking the print result. An example of the print setting changing function includes a color adjustment function for adjusting the hue of the print result. As specific setting items for such a color adjustment function, monochrome printing for printing a document in monochrome can be set, and color adjustment by changing adjustment items such as density and contrast can be performed. When the color adjustment function is provided in the print preview function, it is desirable that the set contents be reflected immediately because the color adjustment contents set by the user are confirmed in the print preview display. If the image generation unit creates display image data for print preview, color adjustment can be reflected on the created display image data for display. However, when the above-mentioned XPS format data is transferred to the OS and print preview is performed, it is necessary to reflect the color adjustment in advance in the XPS format data itself to be transferred to the OS. In that case, in order to perform print preview, XPS format data must be analyzed and all colors such as images and character strings contained in the XPS format data must be converted. It becomes. In order to reduce such processing, there has been proposed a method using pixel data processing in which pixel data generated for image display is converted and display content is changed without processing the XPS format data in advance. ing. The pixel data processing can be executed by, for example, a pixel shader provided by Microsoft's DirectX.

  As actual processing, for example, by assigning a module pre-installed with pixel data processing to a control that performs screen display (hereinafter referred to as display control), the pixel data displayed according to the corresponding display control is converted. Is done. As a result, the color adjustment result designated by the user using the print preview function can be reflected in the displayed pixel data without converting the XPS format data in advance.

JP 2009-282844 A

  Conventionally, the number of instructions that can be used for pixel data processing may be limited. One pixel data process can be assigned to one display control. Therefore, when the conversion process is complicated, there is a problem in that all necessary processes cannot be performed within such a limited range. Specifically, for example, in the above-described color adjustment, a plurality of setting items such as brightness, density, contrast, and color tone may be set, and conversion processing corresponding to all of them is performed by one pixel data processing. It is difficult. As a result, there is a problem that the preview display reflecting the changed contents of all setting items cannot be performed.

  Even if there is no limit on the number of instructions, performing many processes at once may increase the processing time and reduce the calculation accuracy.

  Therefore, according to the present invention, when the display content is converted according to the setting value by the pixel data processing, the setting content is displayed even when the number of commands appropriate for handling by one pixel data processing is exceeded. It is intended to be reflected in the pixel data.

The present invention is an information processing apparatus for displaying image data based on data of a plurality of layers, wherein a receiving unit that receives a print setting value, a first image process based on the print setting value is assigned to the first layer, and Allocating means for allocating the second image processing based on the print setting value to the second layer, and superimposing the data of the first layer and the data of the layer higher than the first layer on the first layer Data is generated, the first image processing is applied to the first data, the first data to which the first image processing is applied, and the second layer lower than the first layer. by overlapping the data, second data is generated, the in the second image processing to be applied to the second data, the image data to be displayed is generated It is characterized in.

  According to the present invention, even when the number of instructions suitable for handling by one pixel data process is exceeded, it is possible to apply a conversion process for reflecting a set value to displayed pixel data.

It should be noted that the following embodiments do not limit the present invention according to the claims, and all combinations of features described in the present embodiments are not necessarily essential to the solution means of the present invention. .

<Example 1>
<Configuration of printing system>
<Hardware configuration diagram of information processing apparatus>
FIG. 1 is a block diagram showing the configuration of a personal computer (hereinafter referred to as PC) 101. The PC 101 includes a CPU 103, a RAM 105, a ROM 107, a hard disk 109, a communication interface 111, a display device 113, a mouse 115, a keyboard 117, and a system bus 119. The CPU 103 calculates, determines, and controls data and instructions according to programs stored in the RAM 105, the ROM 107, or the hard disk 109. The RAM 105 is used as a temporary storage area when the CPU 103 performs various processes. The hard disk 109 stores an operating system (OS), a browser, other application software, and the like. That is, the CPU 103 normally reads out a program stored in the ROM 107 or the hard disk 109, installs it in the RAM 105, and executes various programs by executing the program using the RAM 105 as a work memory. The communication interface 111 is, for example, an interface for performing data communication with a printer, such as USB, SCSI, or wireless, or a network interface for transmitting / receiving data to / from an external WWW server via the Internet. The display device 113 includes a CRT, a liquid crystal display, and a graphic controller, and performs display on a graphic user interface (GUI). The mouse 115 and the keyboard 117 are input devices for the user to give various instructions to the PC 101. The system bus 119 exchanges data with the CPU 103, RAM 105, ROM 107, hard disk 109, and the like.

<Printer driver operation>
FIG. 2 is a block diagram conceptually showing the printing system executed on the PC 101 in this embodiment, focusing on the OS print support function and printer driver.

  In the printing system shown in FIG. 2, print data created by the application 201 is temporarily stored in the XPS spool file 217 through the OS print support function 213. The stored print data is converted into a print command interpretable by the printer based on the print setting information by the filter group 219 of the printer driver, and is supplied to the printer 231 for printing.

  The user interface module 215 provides a function for a user to set a paper size, a printing direction, and other attributes that are generally used for printing. At the same time, the user interface module 215 in the present invention has a function of starting a print preview function for displaying a print image on the display device 113 before starting a printing operation by the printer. The user interface module 215 sends print setting information in which setting values of a plurality of print setting items are stored to the application 201.

  When printing the created arbitrary document, the application 201 instructs the OS print support function 213 to start printing or end printing, and transmits the print setting information received from the user interface module 215 to perform print settings. . It also instructs the drawing start and drawing end of each page of the document. The OS print support function 213 stores (or spools) print data and print setting information created by the application in the XPS spool file 217. Each filter is called from the print support function of the OS when reading (or despooling) spooled print data.

  The printer driver filter group 219 includes one or more filters. When printing, the print data is read from the XPS spool file 217, converted into a print command interpretable by the printer, and supplied to the printer 231 for printing. It has a function. The filter group 219 in this embodiment includes a layout filter 221 that is a layout processing unit, a preview filter 223 that is a preview document creation unit, and a print command filter 225 that is a print command conversion unit. However, the layout function and the print preview function can be realized by one filter, or unnecessary filters can be removed, and the filter used in this embodiment is not limited to the above filter configuration.

  The layout filter 221 receives the XPS format data stored in the XPS spool file 217 as input, performs page layout processing based on the print setting information, and outputs laid out XPS format data. The layout processing in this embodiment includes, for example, N-up printing that prints a plurality of pages on one sheet surface, poster printing that prints one page on a plurality of sheet surfaces, and the like, but is not limited thereto. .

  The preview filter 223 receives the layout-completed XPS data output from the layout filter 221 as an input, and executes print preview processing using the preview control module 203 for the user based on the print settings. The preview filter 223 determines whether or not the print preview setting of the print data is ON. If it is ON, the preview filter 223 activates the preview control module 203 and passes the XPS format data as print data to the preview control module 203. The preview control module 203 displays the printing result on the display device 113 by displaying the XPS format data. The configuration of the display screen provided by the preview control module 203 will be described later with reference to FIG. Since the print preview is not performed when the print preview setting is OFF, the preview filter 223 transmits the print data to the next filter.

  The print command filter 225 receives the print data output from the preview filter 223 as an input, converts the XPS format data into a print command interpretable by the printer, and outputs it in accordance with the print setting information. The print command filter 225 is generally called a render filter when converting inputted XPS format data into image data. Render filters are often used in printer drivers for inexpensive raster printers typified by inkjet printers. When the print command filter 225 operates as a render filter, the input XPS format data is once converted into image data. Thereafter, the image data is converted into a print command that can be interpreted by a raster printer through image processing steps such as color space conversion and binarization. When a high-function printer represented by a page printer can interpret XPS format data, the print command filter 225 edits the input XPS format data and outputs XPS format data. Needless to say, if the print command filter 225 does not require processing, the input XPS format data is output as it is, or the print command filter 225 need not be included in the printer driver from the beginning.

  The printer 231 serving as an output device interprets the print command generated by the print command filter 225 and forms a visible image on the printing paper. Note that the print sheet 241 in the print result example illustrated in FIG. 2 conceptually illustrates an example in which the layout filter 221 performs the 2-up process.

<Preview control module preview window>
FIG. 3 shows an example of a display screen (preview window) provided by the preview control module 203 in this embodiment. In this embodiment, the print preview window 301 uses a liquid crystal screen to which a touch panel is attached. As a result, the print preview window 301 has both a function as a display area for displaying the print settings of the preview image and print data, and a function as an input unit for the user to change the display method of the preview image. Can be equipped with. However, a display area and an input unit can be provided separately.

  The menu bar 303 has a menu format, and the user can select an instruction to be given to the preview control module 203 such as display switching. The document list 305 displays a list of print data that can be currently processed by the preview control module 203. Therefore, in this embodiment, the print data selected in the document list 305 is a display or print target. The page number column displays the number of pages of the selected print data. The preview display area 307 uses print preview XPS format data to display print data in a layout or color tone that is considered to be actually formed on a print sheet. Using the user operation unit of the tool bar 309, the user can switch the display page and change the display size. In a display area 311, setting values of typical setting items related to print settings of print data for which the print preview function is currently displayed are displayed. Referring to FIG. 3, it can be understood that the page number currently displayed in the preview is the first page, and the number of copies set in the print setting is one.

  In the print setting change area 313, setting values of representative setting items related to the print settings of the selected print data can be displayed and the setting values can be changed. In this embodiment, the preview control module 203 has a function of adjusting the color of print data, and can change color tone, brightness, density, contrast, and the like. When the change of the setting contents affects the print result, it is necessary to update the preview display area 307 according to the changed setting contents. With this update, the user can check how the printed contents are changed as a result of changing the setting contents. The user confirms the print result and changes the print settings, and then presses the print button 315 to instruct the start of printing of the print data selected in the document list 305.

<Preview display area configuration>
FIG. 4 is a diagram showing a general configuration of the print result display displayed in the preview display area 307. The preview display area 307 includes a document display control 401 and a base display control 403. By specifying the XPS format data to be printed in the document display control 401, the OS displays the specified XPS format data. The base display control 403 is provided to represent paper, and when the white area is set with a size corresponding to the paper size of the print setting, the OS draws the white area with a size corresponding to the paper size according to the setting. The base display control 403 can display the paper size, margins, and the like that are considered to be actual print results, and can faithfully reproduce the output results.

  The document display control 401 and the base display control 403 have a layer structure, and the document display control 401 is located in an upper layer of the base display control 403. When the preview display is executed, the OS displays pixel data 405 in which the document display control 401 and the base display control 403 are superimposed. Changes made to the control of the lower layer are made to the overlay result including the upper layer. Therefore, when reflecting the change contents of the print setting change area 313, the preview control module 203 designates pixel data processing to the base display control 403. As a result, pixel data processing is reflected on the superimposed pixel data 405, and the changed print settings can be reflected in the preview display area 307.

  However, the number of instructions that can be used for pixel data processing may be limited. As an example of the restriction on the number of instructions, the number of instructions is set for each arithmetic operation such as addition or multiplication, and an upper limit is set for the total number of instructions executed in the pixel data processing. Even when there is no limit on the number of instructions, it is conceivable that processing is slowed down or calculation accuracy is reduced by performing many processes in one pixel data process.

  That is, generally, for one pixel data processing, there is an appropriate number of instructions depending on the system or apparatus. However, there are many setting items that affect the display, such as color tone adjustment setting items, and if the corresponding conversion processing is performed, the number of commands suitable for one pixel data processing may be exceeded. There is. Since one pixel data process can be designated for one display control, a plurality of pixel data processes cannot be designated for the base display control 403. Therefore, it is necessary to reflect a plurality of pixel data processes in combination.

  FIG. 5 is a diagram illustrating an example of a configuration for applying a plurality of pixel data processes to preview display in view of the above-described problem. A pixel data processing display control 407 is added below the conventional document display control 401 and the base display control 403. The pixel data processing display control 407 includes the entire range of the document display control 401 and is arranged in the preview display area 307 at the position and size included in the base display control 403. Since the pixel data processing display control 407 exists below the base display control 403 and is a size included in the base display control 403, the pixel data 409 that is the final display content is affected even if they are superimposed. Don't give.

<Pixel data processing allocation>
FIG. 6 is a diagram illustrating a process flow in which a plurality of pixel data processes are applied to display during display update. As described above, the preview display area 307 includes the document display control 501, the base display control 503, and the pixel data processing display control 505. The preview control module 203 executes pixel data processing in a plurality of parts.

  In this embodiment, the pixel data processing is divided into two, pixel data processing 1 and pixel data processing 2. In pixel data processing 1 (509), conversion processing corresponding to monochrome conversion, brightness, density, and contrast changes is performed, and in pixel data processing 2 (513), conversion processing corresponding to color tone changes is performed. Here, it is necessary to execute the two pixel data processes in consideration of the order of the execution order in which the conversion process is applied. In the present embodiment, a desired color adjustment result can be obtained by applying conversion corresponding to color tone to the result of applying conversion corresponding to brightness, density, and contrast. Therefore, the preview control module 203 divides pixel data processing with the above-described configuration, and performs pixel data processing in an appropriate order. In the pixel data processing 1, conversion processing corresponding to a plurality of setting items is performed. However, conversion processing based on each setting performed in the pixel data processing 1 is also performed in the order to be executed. Must be implemented.

  In addition, since the pixel data processing needs to be processed earlier to correspond to the higher layer, it is necessary to assign the display control of the upper layer from the conversion processing performed first. Accordingly, the preview control module 203 assigns the pixel data processing 1 to the base display control 503 and assigns the pixel data processing 2 to the pixel data processing display control 505. Furthermore, when assigning pixel data processing to display control, the preview control module 203 passes the current setting value of the setting item used in each pixel data processing as a parameter. Thereby, the pixel data processing performs a conversion process according to the set value, and the change of the setting content is reflected in the displayed pixel data.

  As described above, when each pixel data process is assigned to the display control, the OS generates pixel data in accordance with the pixel data process assigned by the preview control module 203. A process for generating pixel data according to the pixel data process assigned by the preview control module 203 by the OS will be described by taking an example in which displayed pixel data is updated. First, the OS generates pixel data 507 in which the document display control 501 and the base display control 503 are superimposed. Next, the OS applies the conversion process set in the pixel data process 1 (509) assigned to the base display control 503 to the pixel data 507, and corresponds to the monochrome conversion and the set values of brightness, density, and contrast. Perform conversion.

  The result of the pixel data processing 1 (509) performed by the OS on the pixel data 507 and the pixel data processing display control 505 are overlapped to generate pixel data 511. The OS applies the pixel data processing 2 (513) assigned to the pixel data processing display control 507 to the pixel data 511 to generate pixel data 515. This pixel data 515 is displayed in the preview display area 307. Through the processing as described above, the preview control module 203 realizes preview display to which pixel data processing is applied.

  The pixel data processing can be divided by an arbitrary number. When three or more pixel data processings are applied, it is necessary to arrange pixel data processing display controls according to the number of divisions. Accordingly, the pixel data processing division method is not limited to the present embodiment, and the pixel data processing can be freely divided within a range in which the processing order of the pixel data processing can be maintained. Is possible. In addition, the display control to be assigned may start with the document display control. In that case, it is also possible to reduce the display control for pixel data processing added. Furthermore, it is not necessary to assign one or more setting items to one pixel data process, and conversion processing corresponding to one setting item can be performed by two or more pixel data processes.

  FIG. 7 is an example of a flowchart illustrating processing in which the preview control module 203 changes the allocation of pixel data processing. Changing the allocation of pixel data processing may be performed when a setting such as color adjustment that affects the printing result is changed, but is not limited thereto. Further, in the example shown in FIG. 7 of this embodiment, it is assumed that the setting contents in the print setting change area 313 are reflected only when the monochrome print setting is ON. It is made to reflect in the allocation. However, even when the monochrome print setting is OFF, the print result is affected, and it is possible to change the setting accordingly.

  First, in S101, the preview control module 203 determines whether or not the monochrome print setting is ON. If it is ON, the process proceeds to S103, and if it is OFF, the process proceeds to S107. In S103, the preview control module 203 assigns pixel data processing 1 (509) to the base display control 503, and proceeds to S105. In step S105, the preview control module 203 assigns the pixel data processing 2 (513) to the pixel data processing display control 505.

  S107 is processing when the monochrome print setting is OFF. In this embodiment, it is assumed that the print setting change area 313 can be set only when the monochrome print setting is ON. That is, when the monochrome print setting is OFF, the print setting change area 313 cannot be set and there is no change. For this reason, the preview control module 203 cancels the pixel data processing respectively assigned to the base display control 503 and the pixel data processing display control 505 in S107. In this embodiment, since it is assumed that the conversion process is not performed when the monochrome print setting is OFF, the pixel data processing is canceled, but another conversion process is performed when the monochrome print setting is OFF. If you want to allocate another pixel data processing. Needless to say, it is not necessary to change the assignment when it is possible to cope with the conversion process when the monochrome print setting is OFF by changing the setting value in the same pixel data processing. When updating the display, the pixel data processing set in S101 to S107 is executed, and the content displayed in the preview display area 307 is converted.

  With the above configuration, conversion processing with a large number of instructions can be reflected in the display.

<Example 2>
According to the first embodiment, conversion processing with a large number of instructions can be realized without problems of processing time and accuracy by using a plurality of pixel data processing. However, when this method is used, pixel data processing is performed every time the assigned layers are overlapped, and there is a problem that processing takes time. Therefore, in this embodiment, the processing time is shortened by assigning and releasing the pixel data processing to the display control in accordance with the changed setting item.

  FIG. 8 is a diagram illustrating an example of pixel data generation processing when the allocation of pixel data processing is switched according to the setting item. In the pixel data processing, the display content corresponding to one or more setting items that can be set in the print setting area 313 is converted. Therefore, it is not necessary to execute pixel data processing in which no change has occurred for the corresponding setting item. Therefore, the preview control module 203 checks the current value of each setting item before the pixel data processing is executed, and changes all the items corresponding to each pixel data processing from the default values that are the default values. Make sure that

  The preview control module 203 cancels the assignment to the display control for pixel data processing in which no corresponding setting item has been changed. As a result, it is possible to perform only the pixel data processing that is not canceled and that is necessary according to the setting. However, it is necessary to perform monochrome conversion for monochrome printing even when only the color tone is converted. For this reason, if monochrome conversion is included only in the pixel data processing 1, the pixel data processing 1 is canceled and the monochrome conversion is not executed even if the other setting items are not changed. In order to avoid this, if the pixel data processing 1 is always assigned, the meaning of this embodiment is lost. Therefore, monochrome conversion, which is a common process, is provided for both pixel data processing 1 and pixel data processing 2. That is, in the pixel data processing 1, monochrome conversion and conversion corresponding to brightness, density, and contrast are possible, and in the pixel data processing 2, monochrome conversion and conversion corresponding to the color tone are possible. Thereby, when only the color tone is changed, the necessary conversion processing can be performed only by the pixel data processing 2.

  FIG. 8 is a diagram showing processing when one of brightness, density, and contrast is changed in the print setting change area 313 and the color tone is not changed. Since the brightness, density, and contrast settings have been changed, the preview control module 203 assigns the pixel data processing 1 to the base display control 503. Since the color tone setting has not been changed, the preview control module 203 cancels the pixel data processing 2 from the pixel data processing display control 507.

  When updating the display, the OS first generates pixel data 507 in which the document display control 501 and the base display control 503 are superimposed. Since the pixel data processing 1 is assigned to the base display control 503, monochrome conversion and conversion processing according to the set values of brightness, density, and contrast are performed on the pixel data 507 including the upper layer. Next, the OS generates pixel data 511 by superimposing the result of applying the pixel data processing 1 to the pixel data 507 and the display control for pixel data processing 507. Since the pixel data processing 2 of the display control for pixel data processing is deallocated, the pixel data 511 becomes the pixel data 515 that is the actual display content as it is, and is displayed in the preview display area 307.

  FIG. 9 is a diagram showing processing when the brightness, density, and contrast are not changed and the color tone is changed in the print setting change area 313. Since the settings of brightness, density, and contrast are not changed, the preview control module 203 cancels the pixel data processing 1 from the base display control 503. Since the color tone setting has been changed, the preview control module 203 assigns the pixel data processing 2 to the pixel data processing display control 507.

  When updating the display, the OS first generates pixel data 507 in which the document display control 501 and the base display control 503 are superimposed. Since the allocation of the pixel data processing 1 of the base display control 503 is released, the OS generates the pixel data 511 by superimposing the pixel data 507 and the pixel data processing display control 505 as they are. The contents of the pixel data 511 are the same as the pixel data 507. Since pixel data processing 2 of the display control for pixel data processing is assigned, the OS performs monochrome conversion on the pixel data 511 and processing according to the set value of the color tone, generates pixel data 515, and previews it. This is displayed in the display area 307.

  If any one of brightness, density, and contrast is changed and the color tone is also changed, as shown in FIG. 6, the preview control module assigns pixel data processing 1 and pixel data processing 2 to corresponding display controls. .

  FIG. 10 is an example of a flowchart illustrating processing in which the preview control module 203 changes the allocation of pixel data processing in accordance with the setting items. First, in S201, the preview control module 203 determines whether or not the monochrome print setting is ON. If it is ON, the process proceeds to S203, and if it is OFF, the process proceeds to S217. In S203 to S209, allocation or cancellation of the pixel data processing 1 (509) is performed. In step S203, the preview control module 203 determines whether any of brightness, density, or contrast, which is a setting item corresponding to the pixel data processing 1 (509), has been changed. If any one has been changed, the process proceeds to S209, and if none has been changed, the process proceeds to S205.

  In step S205, the preview control module 203 determines whether the color tone setting has been changed. If the color tone setting has been changed, the process proceeds to step S207. If not, the process proceeds to step S209. In S207, since the brightness, density, and contrast are not changed and the color tone is changed, it is not necessary to execute the pixel data processing 1 (509). For this reason, the preview control module 203 cancels the assignment to the base display control 503, and proceeds to S211. In S209, any one of brightness, density, and contrast has been changed, or none of brightness, density, contrast, and color tone has been changed. For this reason, the preview control module 203 assigns pixel data processing 1 (509) to the base display control 503, and proceeds to S211. The assignment of pixel data processing 1 (509) when no setting has been changed is for monochrome conversion, but this can also be done by pixel data processing 2 (513). .

  In S211 to S215, allocation or cancellation of the pixel data processing 2 (513) is performed. In step S211, the preview control module 203 determines whether the color tone setting has been changed. If the color tone setting has been changed, the process proceeds to step S213. If not, the process proceeds to step S215. In S213, since the color tone has been changed, the preview control module 203 assigns pixel data processing 2 (513) to the pixel data processing display control 505. In S215, since the color tone has not been changed, the preview control module 203 cancels the pixel data processing 2 (513) from the pixel data processing display control 505.

  S217 is processing when the monochrome print setting is OFF. In this embodiment, it is assumed that the print setting change area 313 can be set only when the monochrome print setting is ON. Therefore, the preview control module 203 cancels the pixel data processing respectively assigned to the base display control 503 and the pixel data processing display control 505 in S217. When updating the display, the pixel data processing set in S201 to S217 is executed, and the content displayed in the preview display area 307 is converted. With the above configuration, unnecessary pixel data processing is not performed, and processing time can be shortened.

  In the first embodiment, the print preview function of the printer driver has been described. However, the present embodiment can be applied to all applications in which display contents are dynamically converted according to settings, and the range is the print preview of the printer driver. It is not limited to functions. The same applies to the second embodiment.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
