Description

  The present invention relates to a printing apparatus that prints a list of index images of a plurality of files.

  In recent years, printers that can print files stored in a portable storage medium such as a memory card without using an information processing apparatus such as a personal computer (PC) have become widespread. In this type of printer, a file stored in the memory card can be directly printed by the printer by connecting the memory card to the printer. The file to be printed includes not only a bitmap image file taken with a digital still camera or the like, but also a document file including character information and image information created on a PC or the like. Further, in such a printer, a list (index) printing function for printing an index image obtained by enlarging or reducing an image indicating each file to a predetermined size on a recording sheet in order to check the file stored in the memory card. It has.

Some applications that function on a PC, such as utility software bundled with a printer as a peripheral device of the PC, have a list printing function as described above. As a list printing method performed by this type of application, for example, a method described in Patent Document 1 is disclosed.
JP 2006-155281 A

  Conventionally, when a document file including a plurality of pages in one file is to be subjected to list printing, an index image of the first page, for example, is printed as a list as a representative page indicating the characteristics of the document file. At that time, if an error occurs in the process of creating the index image corresponding to the first page, instead of printing the index image of the first page, an alternative image (for example, not directly related to the contents of the document file) A measure such as printing a symbol indicating a file type) has been taken.

  However, if a substitute image that is not directly related to the contents of the file is printed instead of the index image of the representative first page, the user cannot know the contents of the file from the list printed result. Inconvenient.

  The present invention has been made to solve the above problems, and provides a technique for printing an index image that allows a user to know the contents of a file when printing a list of document files consisting of a plurality of pages. The purpose is to do.

  In order to achieve the above object, a printing apparatus according to claim 1, wherein a storage unit that stores a factor of an error that occurs when an index image is created, and a storage unit among a plurality of pages included in one file. A page selection unit that selects a page that does not include a stored error cause as a list print target, an index image generation unit that generates an index image corresponding to the list print target page selected by the page selection unit, and an index Output means for printing out a list of index images corresponding to each file created by the image creating means.

  According to the printing apparatus configured as described above, an index image is created by selecting a page that does not include an error factor stored in the storage unit from a plurality of pages included in one file. It is possible to reliably print an index image of a file by avoiding an error in the process of creating an image. Therefore, when printing a list of document files consisting of a plurality of pages, it is possible to print an index image that allows the user to know the contents of the file.

  The cause of the error stored in the storage means may be, for example, storing an assumed error factor in advance, but if an error actually occurs when creating an index image, the error It is possible to identify and memorize the factors.

  Therefore, it is preferable to configure as described in claim 2. In other words, when an error occurs during index image creation by the index image creating means, an error factor identifying means for identifying the cause of this error, and an error factor for additionally recording the error cause identified by the error factor identifying means in the storage means Recording means. The page selection unit, when an error occurs when creating the index image by the index image creation unit, of the plurality of pages included in the file, another list that does not include the error factor stored in the storage unit Select a new print target.

  By doing this, even if an error occurs when creating an index image for a page, you can avoid the error by creating an index image for another page that does not include the cause of the error, and the file The index image can be printed reliably.

  In addition, when printing a list of files having a plurality of pages, it is common to create an index image for a predetermined specific representative page (for example, the first page). Therefore, it is preferable to configure as described in claim 3. That is, it further comprises error factor determination means for determining whether or not an error factor stored in the storage means is included in the page for which the presence or absence of the error factor is determined. The index image creating means creates an index image corresponding to a predetermined initial print target page from a file including a plurality of pages. At this time, if an error occurs during the creation of the index image corresponding to the page to be initially printed, the error factor determining means targets a page different from the page to be initially printed in the file as a storage means on the page. It is determined whether or not a stored error factor is included. When the error factor determining means determines that the error factor is included in the page, the error factor determining means further performs the determination process by the error factor determining means for a page that has not been determined by the error factor determining means. On the other hand, if it is determined that the error factor is not included, the page is selected as a list print target by the page selection unit, and the determination process by the error factor determination unit is terminated.

  By configuring in this way, even if an error occurs when printing a list for a designated representative page, other pages that do not contain the cause of the error in the same file are printed as a list. Is preferable.

  By the way, as a criterion for selecting pages to be printed as a list, it is an important factor that not only error factors are included but also information useful to the user is included. In this case, it is desirable that the information useful for the user includes information that allows the user to easily infer the contents of the file by looking at the index image printed as a list.

  Therefore, a configuration as described in claim 4 is preferable. That is, the error factor determination means determines whether or not an error factor is included in a page in which a headline recorded in the table of contents data attached to the file is included in the document. The table of contents data is attribute data that holds an outline of the document table of contents etc. accompanying the body data of the document file, and is used when, for example, obtaining an outline of the document on the application. .

  In this way, a page including the document heading is selected as a list printing target. Then, if the user reads the headline recorded in the index image corresponding to the page, the user can analogize the contents of the document file at a glance, which is convenient.

  On the other hand, as a criterion for selecting pages to be printed as a list, importance may be placed on a small processing load for creating an index image. An excessive processing load to create an index image itself can cause errors, while a small processing load to create an index image completes list printing faster. It leads to what can be done.

  Therefore, it is preferable to configure as described in claim 5. That is, the page selection unit selects, as a list print target, a page whose data amount of image information included in one page is equal to or less than a reference amount.

  Image information generally has a considerably larger data amount than character information, and a corresponding processing load is required to create an index image of a page including image information. Therefore, the processing load related to index image creation can be reduced by selecting pages that contain image information with a data amount within the allowable range in terms of processing load as the list print target according to the processing capability of the printing device. The list print can be performed at high speed. Alternatively, it may be possible to thoroughly reduce the processing load related to the creation of the index image by selecting, as a list print target, a page that does not include any image information, that is, only text information.

  Alternatively, not only the data amount of image information but also the data amount of the entire page including the data amount of character information may be taken into consideration, and pages with a lighter processing load may be selected as a list print target. Therefore, it is preferable to configure as described in claim 6. That is, the page selection means selects, as a list print target, a page whose predetermined index indicating the amount of data for one page or the amount of data for one page is equal to or less than a reference value. The predetermined index indicating the amount of data is an index that can be used to analogize the amount of data even if it is not a value indicating the amount of data itself. An example is the number of commands that define the structure of image information. With this configuration, it is possible to select a page with a data amount in a range that is allowed in terms of processing load as a list print target, and to reduce the processing load related to creation of an index image.

  On the other hand, as a criterion for selecting a page to be printed as a list, in addition to not including an error factor, it may be emphasized that the page is easy to browse for the user. For example, in list printing, there is a possibility that a reduced image may be printed than during normal printing, so if you print a list of pages that consist of only small characters, the characters are too small on the output index image This makes it difficult to read.

  In order to solve such a problem, it is preferable to configure as described in claim 7. In other words, the page selection means selects, as a list print target, pages whose size of characters included in one page is equal to or larger than the reference value. Note that the reference character size may be set as appropriate according to the enlargement / reduction ratio of the index image.

  With this configuration, an index image can be reliably printed while avoiding errors, and a page on which the characters can be surely read on the index image is selected as a list print target. Easy to print list.

  Next, the printing apparatus according to claim 8 further includes page information adding means for adding an image of page information related to the page to the index image corresponding to the list printing target page created by the index image creating means. It is characterized by that. Note that the page information is information that can specify which page the index image printed in a list corresponds to.

  In this way, the user can know at a glance which page of the document file the index image printed in a list corresponds to. In particular, when an error occurs in a page that is predetermined as a list printing target, the user can know which page is the list printing target page selected as an alternative, which is convenient.

  In addition, according to a ninth aspect of the present invention, the information processing apparatus further comprises page information determination means for determining whether or not the page to be printed in a list includes contents corresponding to the page information, and the page information addition means includes the page information determination When it is determined by the means that the content corresponding to the page information is not included, the page information is added to the index image corresponding to the page, while when the content corresponding to the page information is determined to be included, It is preferable that the page information is not added to the index image corresponding to the page.

  Next, the program according to claim 10 is generated at the time of creating an index image stored in a storage unit among a plurality of pages included in one file including a document including at least one of character information and image information. Supports a page selection procedure for selecting one page that does not contain an error cause as a list print target, an index image creation procedure for creating an index image corresponding to the selected list print target page, and multiple files created And causing the computer to execute an output procedure for printing each index image as a list.

  By introducing the program configured as described above into a computer included in the printing apparatus, the same effect as that of the printing apparatus according to claim 1 can be obtained. In addition, by installing this program in a PC to which a printing apparatus is connected, the program can be used as an application that functions on the PC.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The CPU 10 is a device that executes various calculations according to programs and data stored in the ROM 12, and the CPU 10 executes calculation processes related to various functions such as the printer function, the scanner function, and the copy function described above.

  The ROM 12 is a storage device that retains stored contents even when the printing apparatus 1 is turned off. The ROM 12 stores programs for controlling the above-described printer function, scanner function, copy function, and read-only data that is not normally updated. I remember it.

  The RAM 14 is a storage device used as a main memory that is directly accessed from the CPU 10. In the RAM 14, various programs executed by the CPU 10 are read from the ROM 12, and various calculation results and various data by the CPU 10 are also stored. When executing the arithmetic processing related to the various functions described above, a program for executing each processing is read from the ROM 12 into the RAM 14. And according to the program memorize | stored in RAM14, CPU10 will perform a process.

  The data input unit 16 includes a connector for connecting a memory card 28 that is a portable storage medium incorporating a flash memory, and has a function as a reader / writer for reading and writing data from and to the memory card 28.

  The operation unit 18 includes a group of key switches such as a numeric keypad, character keys, and function keys, and inputs a command corresponding to a key operation by the user to the CPU 10. The display unit 20 is an output device configured with a liquid crystal display or the like, and displays various information such as an operation state of the printing apparatus 1, operation guidance, and a reduced image of a file.

  The printing unit 22 is an apparatus that prints an image on a recording sheet based on control from the CPU 10 by, for example, an inkjet method or a laser method. The reading unit 24 is a device that scans an image recorded on a recording sheet, converts the read image into digital data, and inputs the digital data to the CPU 10.

  The communication I / F 26 is a hardware interface for connecting the printing apparatus 1 to another information processing apparatus and the like. For example, a serial bus such as a USB (Universal Serial Bus), a network adapter, or the like is used. FIG. 1 shows a state where the printing apparatus 1 and the PC 100 are communicably connected via the communication I / F 26.

  On the other hand, the configuration of the PC 100 is the same as that of a known computer device, such as a display unit 102 configured with a liquid crystal display or the like, an operation unit 104 configured with a mouse and a keyboard, a CPU 106 performing various arithmetic processes, an IPL, a BIOS, and the like. ROM 108 that stores some programs, read-only data, and the like, RAM 110 that is a main memory that is directly accessed from the CPU 106, and a hard disk drive that is an auxiliary storage device for storing OS, application programs, and various data files , HDD) 112, and a communication I / F 114, which is a hardware interface for connecting a printer and other peripheral devices to the PC 1, and connecting the PC 1 to a network.

  The printing apparatus 1 of the present embodiment connects a memory card 28 used in a digital camera or the like to the data input unit 16 in addition to a function of executing printing based on print data input as a peripheral device of the PC 100, and the memory A so-called direct printing function for directly reading and printing data from the card 28 is provided. Further, as a function related to this direct printing, an index image corresponding to each file is created from a plurality of document files (for example, PDF (Portable Document Format) files etc.) stored in the memory card 28, A list of the index images is printed. At this time, usually, the first page among a plurality of pages included in one file is selected as a list printing target, and an index image of the first page is created to perform list printing. In addition, as a characteristic process in the present invention, when an error occurs when the index image corresponding to the first page that is the target of list printing is generated, the CPU 10 of the printing apparatus 1 selects another page that does not correspond to the error. A process for creating an index image by selecting it as a list printing target is executed.

[Description of list print processing]
Next, an example of the above list printing will be described with reference to FIG. FIG. 2 is an explanatory diagram schematically showing the procedure of list printing. In the example shown in FIG. 2, it is assumed that index images of three files (file 1, file 2, and file 3) stored in a folder in the memory card 28 are printed. As the procedure, index images are sequentially created for each file, and these index images are arranged at predetermined positions on a recording sheet and printed. Here, as a general rule, the first page among a plurality of pages included in the list printing target file is the index image creation target. On the other hand, if an error occurs when creating the index image of the first page, an index image of another page not corresponding to the cause of the error is created instead of the first page. In the example shown in FIG. 2, an index image of the first page is created for files 1 and 2, but an error has occurred in the creation of the index image of the first page for file 3, so that from another page An index image is created and a list of files is printed.

[Description of index image creation processing]
Next, detailed contents of the procedure for creating an index image from each file in the above-described list printing process will be described with reference to the flowcharts of FIGS. 3 and 4 and the explanatory diagrams of FIGS.

  FIG. 3 is a flowchart illustrating a procedure of index image creation processing executed by the CPU 10 of the printing apparatus 1. This process is a process that is executed for each file that is the target of list printing.

  The CPU 10 first sets the first page of the file as a processing target (S100). Next, the character data and image data included in the set processing target page are converted to create print data of the index image of the page, and the page is set as processed (S110). Here, it is determined whether or not an error has occurred when the index image of the processing target page is created (S120). If it is determined that an error has occurred (S120: YES), the error factor storage process of S130 is performed. Execute.

  Here, the detailed contents of the error factor storage process in S130 will be described with reference to FIG. FIG. 4 is a flowchart illustrating a procedure of error factor storage processing executed by the CPU 10 of the printing apparatus 1.

  In the error factor storage process, first, it is determined whether or not the cause of the generated error is a font error (S131). Here, the font error is an error indicating that the font used for the character included in the processing target page is not supported by the printing apparatus 1 and the character cannot be printed correctly. .

  If it is determined that the error factor is a font error (S131: YES), the error font is stored in the RAM 14 as an error factor (S132), and the error factor storage process is terminated.

  On the other hand, when it is determined that the error factor is not a font error (S131: NO), it is determined whether the error factor is an image error (S133). Here, the image error means that the data format of the image included in the page is not supported by the printing apparatus 1, and the state in which the image cannot be printed correctly or the size of the image included in the page expands the print data. This is an error indicating that the memory capacity is too large to print and the image cannot be printed.

  When it is determined that the error factor is an image error (S133: YES), the image having the error is stored in the RAM 14 as an error factor (S134). On the other hand, if it is determined that the error factor is not an image error (S133: NO), the error factor storage process is terminated.

  Next, in S135, it is determined whether or not the memory for storing the print data generated at the time of printing is full (S135). If it is determined that the memory is full (S135: YES), the image size of the image error that caused the error in S133 is stored in the RAM 14 (S136), and the error factor storage process is terminated. On the other hand, when it is determined that the memory is not full (S135: NO), for example, when there is a cause in the image that has caused the error, the error factor storage process is terminated.

  Returning to the flowchart of FIG. After identifying and storing the error factor in the error factor storage process of S130, it is determined whether there is an unprocessed page among the pages included in the file (S140). If it is determined (S140: YES), it is determined whether the number of processed pages exceeds a predetermined limit number (S150). When it is determined that the number of processed pages does not exceed the limit number (S150: NO), the next page to be processed is selected from the unprocessed pages among the pages included in the file and set as the target for processing. (S160).

  Here, a specific procedure for selecting the next page to be processed will be described with reference to FIG. FIG. 5 is an explanatory diagram showing a procedure for selecting a page to be processed from a document of a file attached with table of contents data.

  FIG. 5A is a diagram schematically showing the structure of a file to which table of contents data is attached. This file is accompanied by table of contents data in addition to the document data which is the main data of the file. The table of contents data is attribute data that retains information such as a table of contents in which the headline of the document is written along with the body data of the document file, and is used when, for example, obtaining an outline of the document on the application. Is.

  To select a page to be processed from a file with table of contents data attached, first, document heading information is acquired from the table of contents data (1). Next, a page including the headline sentence indicated by the acquired headline information is searched from the document data of the file (2). As a result of the search, one page including the headline is acquired and selected as the next processing target (3). When there are a plurality of pages including a headline sentence, for example, a page with a lower page number is selected with priority. When the table of contents data is not attached to the file, the unprocessed pages are selected as the processing target in order from the page with the smallest page number.

  FIG. 5B is a diagram illustrating an example of a page selected as a processing target. On this page, a headline corresponding to the headline information included in the table of contents data is described so that the user can easily understand the contents of the document. In S170 and S180, which will be described later, the presence or absence of an error factor and suitability with other selection conditions are determined for the selected processing target page (4).

  Returning to the flowchart of FIG. After selecting the next page to be processed in S160, it is determined whether this page to be processed corresponds to the error factor stored in the RAM 14 (S170). That is, it is determined whether or not the page to be processed includes the same error factor as the error factor (font error or image error) stored in the RAM 14 in the error factor storage process (see FIG. 4). Here, when it is determined that the page to be processed does not correspond to the error factor stored in the RAM 14 (S170: NO), it further satisfies other selection conditions for selecting the page as a list printing target. It is determined whether or not (S180).

  More specifically, conditions for selecting the page as a list printing target are as follows: (1) The data amount of the image included in the page is equal to or less than a reference amount (including no image); (2 ) Selection conditions such as the number of commands that define the structure of characters and images in the document are below the reference value, and (3) the size of the characters included in the page are above the reference value. Apply. Among these, the selection conditions (1) and (2) are selection conditions that place emphasis on selecting pages that can reduce the processing load related to creation of index images and perform list printing at high speed. On the other hand, the selection condition (3) is a selection condition that places emphasis on the legibility of characters in the index image printed in a list. Note that all of the selection conditions (1) to (3) may be applied to the processing of S180, or only a part may be applied. Further, as the reference amount of data in the selection condition (1) and the reference value of the number of commands in the selection condition (2), a fixed value may be used according to the processing capability of the printing apparatus 1, or processing in real time. A configuration in which each reference value is dynamically determined within an allowable range according to the load may be employed.

  If it is determined in S180 that the page meets the selection conditions (S180: YES), the process proceeds to S110, character data and image data included in the page to be processed are converted, and the index image of the page is converted. Create print data.

  On the other hand, if it is determined in S170 that the page to be processed corresponds to the error factor stored in the RAM 14 (S170: YES), or if it is determined in S180 that the page to be processed does not meet the selection conditions ( (S180: NO), the page is set as processed, and the process returns to S140. If it is determined in S140 that there is no unprocessed page (S140: NO), or if it is determined in S150 that the number of processed pages exceeds the limit (S150: YES), an alternative prepared in advance The drawing data of the image is developed in the printing memory (S210), and the index image creation process is terminated. In this case, the substitute image is printed as a list as an index image of the file. As the substitute image, for example, a symbol indicating a file data format (for example, PDF) may be used.

  On the other hand, when it is determined that no error has occurred when the index image is created in S110 (S120: NO), it is determined whether or not the page to be processed is the first page (S190). When it is determined that the page to be processed is the first page (S190: YES), the index image creation process ends. In this case, the index image created in S110 is printed as a list as the index image of the file as it is.

  On the other hand, when it is determined that the page to be processed is not the first page (S190: NO), page information indicating a page number or the like is added to the index image created in S110 (S200), and the index image creation process is terminated. To do. In this case, an image in which page information is added to the index image created in S110 is printed as a list as an index image of the file.

  Here, a procedure for adding page information on the index image will be described with reference to FIG. As shown in FIG. 6, when an index image is created from a page (b) to be processed other than the first page among a plurality of pages included in the file (a), a page number is displayed in the header or footer portion of the page. If the page information such as page number is not described, the page information such as the page number is added to the footer portion on the index image. FIG. 6D is an example of an index image to which page information is added.

  On the other hand, when the page information is originally described in the header or footer portion of the page to be processed, the page information is not added on the index image. That is, as shown in FIG. 6E, the created index images are printed as a list as they are.

[effect]
The printing apparatus 1 according to the embodiment has the following effects.
(1) When printing an index image of a file as a list, even if an error occurs when creating an index image of the first page that is the initial print target, another page that does not include the cause of the error is printed as a list Is preferable.

  (2) Instead of the page in which an error has occurred, a page in which a headline recorded in the table of contents data attached to the file is included in the document is selected as a list print target. In this way, if the user can read the headline recorded in the index image corresponding to the page, the user can estimate the contents of the document file at a glance, which is convenient.

  (3) Instead of the page in which an error has occurred, a page including an image having an amount of data in a range allowed in terms of processing capability of the printing apparatus is selected as a list print target. By doing so, it is possible to reduce the processing load related to the creation of the index image and to perform list printing at high speed. Alternatively, it is possible to thoroughly reduce the processing load related to the creation of the index image by selecting a page that contains no images, that is, only characters, as a list print target.

  (4) Instead of the page in which an error has occurred, by selecting a page whose number of commands defining the character and image structure in the document is equal to or less than the reference value as a list print target, The processing load can be reduced.

  (5) Instead of the page where the error occurred, select the page whose character size included in the page is greater than or equal to the reference value as the list print target, and print the index image reliably avoiding the error This makes it possible to realize list printing that is easy for the user to view.

  (6) By adding an image of page information related to the page to the index image corresponding to the page selected as an alternative to the first page, the user can determine which page of the document file the index image printed as a list corresponds to. It becomes convenient at a glance and is convenient.

  (7) When the number of pages in which an error has occurred reaches a predetermined number, the index image is not generated using another unprocessed page as the target page, but instead the drawing data of the substitute image is developed. The generation of the index image for the file can prevent the list printing process from being delayed.

[Modification]
As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment at all, It is possible to implement in various aspects.

  For example, in the above-described embodiment, an example in which file list printing is executed by the direct printing function in the printing apparatus 1 has been described. On the other hand, the list printing function in the above embodiment may be installed in the PC 100 as application software that functions on the PC 100 connected to the printing apparatus 1. In this case, the CPU 106 of the PC 100 creates an index image from each of a plurality of files and causes the printing apparatus 1 to print a list of the index images.

  In the procedure for creating an index image, the first page is first set as a page to be processed. However, the present invention is not limited to this. For example, it is defined in advance in the file which page is to be processed as an index image. May be.

  Also, error factors are stored for each file, but error factors that occurred when processing was performed in the past are stored, and when processing other files, these accumulated error factors are used. Further, it may be determined whether or not an error factor is included in the page to be processed.

  Also, instead of unconditionally setting the first page as the processing target page, the first page is first checked for the presence or absence of error factors and whether or not the selection conditions are met. If it matches, the first page may be the page to be processed.
