As shown in FIG. 2, various programs including a file acquiring program 12a, an image page selecting program 12b, a reduced-size image generating program 12c, an output program 12d, a color page selecting program 12e, a leading page information acquiring program 12f, a specific page selecting program 12g, a FAX control program 12h, a scanner control program 12i and a copy control program 12j are stored in the ROM 12.
The file acquiring program 12a is a program for acquiring a file stored in a storage medium 28 or a personal computer (PC) 29. The image page selecting program 12b is a program for selecting a page containing image information from a plurality of pages contained in one file. The reduced-size image generating program 12c is a program for generating reduced-size images of the selected page. The output program 12d is a program for printing or displaying the generated reduced-size images. The color page selecting problem 12e is a program for selecting a page containing color character information or color image information from a plurality of pages contained in one file. The leading page information acquiring program 12f is a program for acquiring information of a leading page of each chapter of a file. The specific page selecting program 12g is a program for selecting a specific page from a plurality of pages contained in one file on the basis of input information.
The FAX control program 12h, the scanner control program 12i and the copy control program 12j which are stored in the ROM 12 are programs for controlling the faxing function, the copying function and the scanning function, respectively.
The compound machine 1 is connected to the NCU 14. The NCU 14 is connected to the public telephone circuit 27 and controls (connects or disconnects) the circuit. The RAM 11 is used as a line buffer memory for an operating region of the CPU 10 and an expanding region of a read image. The modem 15 modulates and demodulates facsimile data. The ROM 12 stores various programs shown in FIG. 2 and data such as setting values therein. The EEPROM 16 stores various flags and setting information therein. The codec 17 codes and decodes facsimile data. The DMAC 18 mainly writes and reads data to and from the RAM 11.
The gate array 13 functions as an input/output interface between the CPU 10 and the units such as the reading unit 21. The reading unit 21 has an image sensor and an LED light source and reads images such as characters and drawing from a manuscript. The printing unit 22 prints the images such as characters and drawing according to an ink jet method or a laser method. The operating unit 23 has a key switch group formed of a ten key and letter keys and transmits an instruction corresponding to a key operation by the user to the CPU 10. The display unit 24 has a panel such as an LCD and displays an operation state, operation guidance and the reduced-size images thereon. The slot unit 25 has a connector for connecting various kinds of storage media 28 having a flash memory such as Smartmedia, Compact Flash (registered trademark), a USB memory therein and functions as a reader/writer for reading or writing data from or to the storage medium 28. The external connecting unit 26 has a connecting port which conforms to standards of centronics parallel interface or USB (Universal Serial Bus) and exchanges data and signals with the personal computer (PC) 29.
The compound machine 1 has a function of printing data as a peripheral device of the personal computer 29 and a so-called direct printing function of directly reading data from the storage medium 28, which is used in a digital camera and the like, inserted into the slot unit 25, and printing the data. As described later, the compound machine 1 outputs reduced-size images 33 of a print document file (for example, a file in pdf (portable document format) format) stored in the storage medium 28 together with a file name 31 and a page number 32 as index images. Similarly, the display unit 24 displays the reduced-size image 33 of the print document file together with a file name 31 and a page number 32 thereon.
FIG. 3 shows an example of index printing. In this embodiment, four files of files 1 to 4 are stored in a storage medium 28. Reduced-size images of the leading pages and pages containing image information are printed in a paper 30.
More specifically, the file is formed of P1 containing only characters and P2 containing image information. The file 2 is formed of only image information (P1). The file 3 is formed of P1, P3 and P5 which contain only characters and P2 and P4 which contain image information. The file 4 is formed of only image information (P1). The file 2 and the file 4 are formed of one page of bitmapped images such as JPEG. The file 1 and the file 3 contain a plurality of pages such as PDF.
In the case of PDF, for example, the image page selecting program 12b determines that the page includes an image when an object type “Image” is written in page data of the page.
The reduced-size images 33 of the leading page (P1) and the page (P2) containing image information in the file 1, the reduced-size image 33 of the leading page (P1) of the file 2, and the reduced-size images 33 of the leading page (P1) and pages (P2, P4) containing image information in the file 3 are printed on the paper 30. Since P3 and P5 of the file 3 contain only characters, the reduced-size images 33 of the pages are not printed. Since only reduced-size images 33 of the leading page (P1) and pages (P2, P4) containing image information in the file 3 are printed, the user can easily grasp contents of the file by looking at the images 33. The reduced-size image 33 of P1 of the file 4 is printed on a second sheet.
In conventional index printing, only one reduced-size image 33 per file is printed. However, in this embodiment, the reduced-size images 33 of a plurality of pages of one file can be printed. By viewing any of the plurality of reduced-size images 33, contents of the file can be easily grasped. The reduced-size images 33 of all target pages may be printed. Further, the maximum page number for printing is set, and the reduced-size images 33 corresponding to the maximum page number may be printed.
The reduced-size image 33 is printed together with a file name 31 and a page number 32. Thus, when performing direct printing, the user can designate the file name 31 and the page number 32 while viewing the result of index printing in FIG. 3.
In the embodiment shown in FIG. 3, a new line is started after P2 of the file 1. In addition, a new line is started after P1 of the file 2. By starting a new line for each file, the user can easily recognize contents of the files when viewing the index printing.
In this embodiment, the leading pages (P1) of the files 1 and 3, which contain only characters, are printed. Only pages containing image information may be printed without printing pages containing only characters. That is, in FIG. 3, only P2 of the file 1, P1 of the file 2, P2 and P4 of the file 3 and P1 of the file 4 may be printed.
Next, FIG. 4 is a flow chart for performing printing shown in FIG. 3. When the user performs an operation of performing index printing, the flow chart is started. First, processing at a step S1 is executed. At S1, it is determined whether or not there exist files. In the case of No at S1, the procedure returns to S1. In the case of Yes at S1, the number of the reduced-size images 33 to be placed on one sheet of the paper 30 or the plurality of paper 30 in the vertical and horizontal directions (m×n) is calculated on the basis of the size of the paper 30 and the reduced-size image 33 at S2.
For example, in the case in FIG. 3, since four reduced-size images and three reduced-size images can be placed in the horizontal direction and in the vertical direction, respectively, it is calculated that m is 4 and n is 3.
Next, the procedure proceeds to S3. At S3, the reduced-size images 33 which satisfy a predetermined condition are generated. In the present embodiment, the pages which satisfy the predetermined condition mean, for example, pages containing image information. Whether image information is contained or not is determined by an image page selecting program 12b on the basis whether, for example, an image command is contained in a target page. Thus, at S3, processing is executed so as to generate the reduced-size image 33 of each page. However, if the image command is not contained in the page, the procedure proceeds to the processing for the next page without generating the reduced-size image of the page.
At S3, the reduced-size image 33 of the page containing color characters or color image information may be generated. Since color characters or color image information are easily viewable, contents of the page can be easily grasped by viewing the reduced-size image 33. To determine whether color characters or color image information are contained, it is determined whether or not a color font, for example, is contained by a color page selecting program 12e. In the case of PDF, for example, the color page selecting program 12e determines that the page is a color page when argument is written with respect to any of cyan, magenta, or yellow in K command of the page. Thus, only the reduced-size image 33 of the page containing the color font can be generated.
At S3, the reduced-size image 33 of the leading page of each chapter may be generated. For example, as shown in FIG. 7, the file is formed of a plurality of chapters. Reference to the leading page of each chapter enables the user to easily grasp contents of the file. In the example shown in FIG. 7, an index page (bookmark) is contained. The index page stores a start page number of each chapter therein. By reading the index page by a leading page information acquiring program 12f for acquiring leading page information of each chapter, the reduced-size image 33 of the page can be rapidly generated. In the case of PDF, for example, the leading page information acquiring program 12f determines that the page is a leading page when an object type “Page” is written in page data of the page. If the text is read from the beginning to the end without using the index page, it takes time. Since file format of the PDF file as shown in FIG. 7 is open to the public, it is possible to determine which part of the file contains bookmark information. The predetermined condition is inputted either from PC 29 via the external connecting unit 26 or from the operating unit 23.
At S3, a specific page may be selected from pages contained in one file by a specific page selecting program 12g on the basis of input information to print the reduced-size image of the selected page. FIG. 8 is a table showing combination of conditions such as character size and font. As shown in FIG. 8, the user can designate MS Mincho or Times New Roman as a specific font and character size (for example, 12 point or less, 14 point or less). Presence or absence of boldface or underline may be also designated. When the page containing a specific font is selected by the specific page selecting 12g, as shown in FIG. 8, the page containing the font designated by the user is selected and the reduced-size image 33 of the page is printed. When a font which is not usually used is designated as the specific font, since the reduced-size image 33 of the page containing the characteristic font which is not usually used is printed, the user can easily grasp contents of the file by viewing the reduced-size image 33. On the contrary, the specific page selecting program 12g selects the page which does not contain the specific font, the page which does not contain the font designated by the user is selected and the reduced-size image 33 of the page is printed. When a font which is usually used is designated as the specific font, since the reduced-size image 33 of the page containing the characteristic font which is not usually used is printed, the user can easily grasp contents of the file by viewing the reduced-size image 33.
Instead of font, a leading page of a chapter, an image page, or, a color page may be selected as the specific page.
Following the processing at S3, the procedure proceeds to S4 and the reduced-size image 33 is placed on a predetermined position on the paper 30. Then, the procedure proceeds to S5, and it is determined whether or not m or all reduced-size images 33 are placed. The state where m reduced-size images 33 are placed means, in the example shown in FIG. 3, the state where four reduced-size images 33 are placed abreast in a line. The state where all reduced-size images 33 are placed means, for example, the state where the reduced-size image 33 of P2 as a last page in the file 1 in FIG. 3 is placed. In the case of Yes at S5, the procedure proceeds to S6. In the case of No at S5, the procedure returns to S3. By repeating the processing at S3 to S5, m or all reduced-size images 33 contained in one file are placed.
At S6, it is determined whether or not the reduced-size images 33 are printed on one sheet of the paper 30 at S6. For example, in FIG. 3, it is determined as Yes when P4 of the file 3 is placed and it is determined as NO in the other cases. In the case of Yes, the procedure proceeds to S7, and the reduced-size images for the paper 30 are printed on the paper 30. Then, at S8, it is determined whether or not all of the reduced-size images 33 contained in all of the files have been placed on the corresponding paper 30. In the cases of No at S6, the procedure also proceeds to S8 without performing printing at S7. In the case of No at SB, the procedure proceeds to S3 for placing all of the reduced-size images 33 contained in all of the files on the corresponding papers 30.
By performing the processes of S3 to SB, the reduced-size images 33 in one file are sequentially placed on one sheet of the paper 30. For example, as shown in FIG. 3, the reduced-size images 33 are placed from the upper left of the paper 30 sequentially. If all of the reduced-size images 33 corresponding to all of the pages contained in one file have been placed on the paper 30, the same processing is performed for a next file. Then, after the sheet 30 has been filled with the reduced-size images 33, the reduced-size images 33 placed on the paper 30 are printed on the paper 30 by the output program 12d. 
Here, the last paper 30 may not have been filled with the reduced-size images 33 even if all of the reduced-size images 33 contained in all of the files have been placed on the papers 30. In such a case, the reduced-size images 33 placed on the last paper 30 are not printed at S7 since the last paper 30 has not been filled with the reduced-size images 33. Therefore, in the case of Yes at S8, it is determined whether or not there exists an unprinted paper 30, that is, whether or not there exists any reduced-size image 33 that has not been printed. In the case of Yes at S8, the unprinted reduced-size images 33 are printed at S9, and then the procedure is finished. In the case of No at S8, the procedure is finished without performing printing at S9.
Next, FIG. 5 shows an example of index display. When an instruction of index display is issued by the user, first, a state shown in FIG. 5(A) is displayed. Here, the reduced-size images 33 of the leading page (P1) and the page (P2) containing image information in the file 1 are displayed on the display unit 24. The reduced-size image 33 of the leading page (P1) of the file 2 is also displayed. Since the reduced-size images 33 of the leading page and the page containing image information are displayed on the screen in this manner, the user can easily grasp contents of the file by viewing the screen.
In this embodiment, the display unit 24 is formed to be smaller than the paper 30 (refer to FIG. 3). When three images and four images are displayed in the vertical and horizontal directions, respectively, as shown in FIG. 3, the reduced-size images 33 become too small and are hard to be seen. Thus, two images and two images are displayed in the vertical and horizontal directions, respectively, as shown in FIG. 5(A).
When a scroll button 34 is pressed to the right in the state shown in FIG. 5(A), the screen moves to a state shown in FIG. 5(B). Here, the reduced-size images 33 of P1, P2 and P4 of the file 3 are displayed. The scroll button 34 is further pressed to the right, the screen moves to a state shown in FIG. 5(C) and the reduced-size image 33 of P1 of the file 4 is displayed. When the scroll button 34 is pressed to the left, the screen returns to the state shown in FIG. 5(B).
FIG. 6 is a flow chart for performing the index display shown in FIG. 5(A) to FIG. 5(C). When the user performs an operation for performing index display, the flow chart is started and processing at a step S10 is performed. At S10, a file to be displayed is calculated on the basis of the operation of the scroll button 34. That is, since the displayed file changes according to the operation of the scroll button 34 as shown in FIG. 5(A) to FIG. 5(C), the file to be displayed is calculated.
Then, the procedure proceeds to S11 and it is determined whether or not the reduced-size images 33 of the target file are generated. In the case of Yes at S11, the procedure proceeds to S13. In the case of No at S11, the procedure proceeds to S12. At S12, m×n reduced-size images 33 of the page which satisfies a predetermined condition in the target file are generated at a maximum and the generated reduced-size images 33 are stored in a reduced-size image management table. To generate the reduced-size images 33 which can be displayed on the display unit 24, m×n reduced-size images 33 are generated at a maximum. The abovementioned reduced-size image management table is a table for managing the reduced-size images 33. For example, a predetermined storage area of the RAM 11 is used to store the table therein. The pages which satisfy the predetermined condition include the page containing image information, the page containing color characters and color image information, the page which corresponds to information designated by the user (specific font, character size and presence or absence of boldface or underline) and the leading page of each chapter. Since the processing of creating the reduced-size images 33 of the pages which satisfy the predetermined condition is described in terms of S3 in FIG. 4, detailed description thereof is omitted.
Then, the procedure proceeds to S13 and processing of placing the reduced-size images 33 to be displayed in a panel display memory is performed. After that, the procedure proceeds to S14 and it is determined whether or not placement of the reduced-size images 33, which is necessary for single display, is completed. In the case of Yes at S14, the procedure proceeds to S16 and panel display is performed. In the case of No at S14, the procedure proceeds to S15 and the next file to be displayed is calculated and then, the procedure returns to S11.
As described above, in the printing or display device in accordance with this embodiment, in the case of a document having a plurality of pages, by printing or displaying the reduced-size image of the page containing an image, the reduced-size image of the page containing a color page, the reduced-size image of the leading page of each chapter or the reduced-size image of the specific page, contents of the file can be easily recognized.
While the invention has been described in detail with reference to the specific embodiment thereof, it would be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention.
