Description

  The present invention relates to a proofreading information processing apparatus having a display section for displaying a proofreading image, and a writing input section capable of giving annotation information of the proofreading image by handwriting input through the display section, and this apparatus. The present invention relates to a calibration information processing method, a program, and an electronic calibration system.

  Recently, in the printing field, proofreading data created on the production side of a printing company, etc., and correction instruction information on the publishing planning side of an ordering company, etc., are communicated to each person who is geographically separated via a communication line. An electronic proofing system that realizes a remote proof that eliminates the exchange of color proofing paper by transmitting and receiving is spreading (see Patent Document 1).

  For example, when the annotation information is displayed together with the image including the calibration image, the display magnification of the image may be changed while the relative size between the image and the annotation information is kept constant. At this time, if the display magnification is set low, handwritten characters as annotation information may not be read. Therefore, various techniques have been proposed for easily confirming the contents of written characters without displaying them in different windows.

  Patent Document 2 discloses a method and system for omitting the content of annotation information in units of characters and displaying a part of the content that is not omitted in a large size.

  Patent Document 3 discloses a method and an apparatus for displaying an enlarged image so as not to fall below the display limit when the size of the annotation information reduced together with the image is below the display limit.

  The printed matter production system 10 according to the present embodiment is configured as described above. Next, the workflow for producing the printed material 64 and the operation of the printed material production system 10 will be described with reference to FIGS. 4 and 5.

  First, the printing operator belonging to the printing company 16 edits the submitted material data and performs DTP processing (step S1). Prior to the DTP processing, the designer belonging to the production company 14 uses the designer terminal 38 to create material data corresponding to the content of the printed matter 64. In response to a transmission instruction from a designer having submission authority, the designer terminal 38 designates the file server 70 (remote server 54) as a transmission destination and transmits the material data. Then, the file server 70 receives and stores the material data via the LAN 34, the gateway 36, the network 18, and the gateway 52.

  The print operator uses the operator terminal 56 to perform necessary operations such as acquisition of material data, preflight processing, and typesetting. At this time, the operator terminal 56 may appropriately receive (send) the data file from the file server 70 via the LAN 50.

  Next, the proofreader receives from the mail server 72 (remote server 54) a notification mail indicating a request for proofreading work (step S2). Here, the proofreader may belong to any of the ordering company 12, the production company 14, and the printing company 16. In the present embodiment, for example, a proofreading operation by a proofreader on the ordering company 12 side is illustrated, but the present invention is not limited to this form. For example, the proofreader terminal 24 (main body 24 a) receives a notification mail from the mail server 72 via the network 18, the gateway 22, and the LAN 20.

  Next, the proofreader downloads proofreading data (first school) from the file server 70 and confirms the proofreading data (step S3). For example, the proofreader terminal 24 (main unit 24 a) acquires proof data from the printing company 16 via the network 18 and performs predetermined signal processing suitable for printing with the printer 28. Then, the printer 28 acquires the print data that has undergone signal processing, and prints the proof 26 based on the print data. Then, the proofreader observes the proof 26 and performs various proofreading operations.

  Next, the proofreader determines whether correction is necessary for the proofreading data (step S4). When it is determined that correction is necessary, the proofreader gives a correction instruction to the designer (step S5). In the electronic proofing system according to the present embodiment, by registering annotation information (annotation) given using the information processing device 32a or the like in the file server 70, a designer who has the authority to view a proofreading image The contents of can be viewed. For example, when the proofreader sends an instruction not to approve the contents of the page to the remote server 54 side, the mail server 72 sends a notification mail to the designer.

  Hereinafter, the operation of the information processing apparatus 32a in step S5 (specifically, addition of annotation information) will be described in detail with reference to the flowchart of FIG. 5 and the functional block diagram of FIG.

  First, the information processing apparatus 32a shifts to the annotation mode in response to a predetermined operation by the proofreader (step S51). In response to the calibration data download instruction, the communication unit 80 receives the calibration data from the printing company 16. The signal processing unit 82 performs desired signal processing suitable for display on the display unit 86 on the calibration data. The display control unit 84 generates a display control signal from the signal-processed calibration data, and displays the calibration image 122 on the display unit 86 (on the display screen 120) based on the display control signal.

  6A and 6B are schematic explanatory diagrams showing screen transitions when annotation information is added to the calibration image 122. FIG.

  On the display screen 120 of the display unit 86, a proof image 122 (in this figure, a magazine page image) is displayed on substantially the entire surface. An icon 124 is displayed in the lower right corner of the display screen 120 so as to be superimposed on the calibration image 122. This icon 124 includes a first icon 126 for switching an editing mode (including an annotation mode) according to the number of touches, a second icon 128 for switching to a writing mode and an eraser mode, and completion of calibration work and storage of settings. It comprises a third icon 130 for indicating. For example, the annotation mode is selected by a predetermined operation by the proofreader, for example, by touching the first icon 126 a predetermined number of times. The writing mode is selected by touching the second icon 128 a predetermined number of times. Furthermore, according to a predetermined touch operation, scroll display of the calibration image 122, change of the display magnification Rd (scale rate of the calibration image 122), and the like are possible.

  Note that the display content of the display unit 86 is updated in a timely manner in response to a touch operation with the touch pen 74 (or the user's fingertip). This function includes detection processing by the writing input unit 88, interpretation processing of writing information by the writing information interpretation unit 90, image creation / update processing by the image creation unit 92, display control by the display control unit 84, and update by the display unit 86. This is achieved through the display.

  Next, the writing area size determination unit 98 determines the size of the writing area 144 (see FIG. 6B) in accordance with a predetermined operation by the proofreader (step S52). Here, the size of the writing area 144 to be determined is a predetermined size common to image information to be written and input as characters. By making the size common, it is possible to reduce the variation in writing of the character size by the same or different workers as compared with the case where there is no limitation on the range of the writing area 144. Further, by providing the writing region 144 having a size that does not depend on the display magnification Rd of the calibration image 122, writing variation is further reduced. Furthermore, by providing a writing area 144 that is large enough to allow a considerable number of characters to be written, information regarding correction can be sufficiently transmitted.

  The unit of size may be the number of pixels, the number of points (font size), or the unit of actual size (for example, mm). In the present embodiment, for example, it is assumed that the number of pixels in the horizontal direction and the vertical direction of the writing region 144 having a rectangular shape is determined as Sx [pixel] and Sy [pixel], respectively.

  Next, the application area specifying unit 104 determines whether or not an input instruction for the image information application position 138 has been received (step S53). Specifically, the application region designation unit 104 determines whether or not there has been a touch operation at any position on the calibration image 122.

  As shown in FIG. 6A, it is assumed that the operator has written and entered a lead line 136 to the correction target portion 134 of the calibration image 122 currently displayed. Then, when it is desired to add annotation information (correct contents) to the end portion of the lead line 136, the operator touches the application position 138 illustrated by the broken line. Then, the provision area designating unit 104 determines that a touch operation has been performed, and proceeds to the next step (S54). On the other hand, if it is determined that there is no touch operation, the process stays at step S53 until the touch operation described above is accepted.

  Next, the grant area size determination unit 100 determines the size of the grant area 140 (step S54). The application region size determination unit 100 acquires the display magnification Rd of the calibration image 122 at the current time, and determines a value proportional to the display magnification Rd as the size of the application region 140. As an example, the number of pixels in the horizontal direction and the vertical direction of the rectangular application region 140 may be determined as K · Rd · Sx [pixel] and K · Rd · Sy [pixel], respectively. Here, K is a positive proportional coefficient. The aspect ratio (ratio between horizontal and vertical) of the application area 140 is (K · Rd · Sx) :( K · Rd · Sy) = Sx: Sy, which matches the aspect ratio of the writing area 144. That is, the application region 140 has the same or similar shape as the writing region 144.

  Next, the grant area designation unit 104 designates the grant area 140 (step S55). As illustrated in FIG. 6B, the grant area specifying unit 104 determines the grant area 140 based on the grant position 138 input in step S53 and the size determined in step S54. Here, the relative positional relationship between the input grant position 138 and the grant area 140 to be specified may be arbitrarily determined. For example, the application area 140 may be arranged with the application position 138 as the center, or the application area 140 may be arranged with the application position 138 as one vertex.

  In the example of FIG. 6B, the designated application area 140 (upper right part of the display screen 120) is displayed on the calibration image 122 in an overlapping manner. Since a border line 142 is attached to the boundary of the grant area 140 that has not yet been written, the operator can grasp the position and size of the grant area 140 in advance.

  Next, the writing area specifying unit 102 specifies the writing area 144 according to the size determined in step S52 (step S56). The designated position may be determined in advance or may be determined according to the application position 138 (relative coordinates on the display screen 120).

  In the example of FIG. 6B, the window 146 (the lower center of the display screen 120) including the writing area 144 is displayed over the calibration image 122. In the upper part of the window 146, a button group 148 for confirming / cancelling writing contents in the writing area 144 is arranged.

  Next, the writing information interpretation unit 90 determines whether or not a character input completion notification has been received (step S57). Specifically, the grant area specifying unit 104 determines whether or not a touch operation on the button group 148 in the window 146 has been performed. If it is determined that the touch operation has been performed, the process proceeds to the next step (S58). If it is determined that there is no touch operation, the process stays at step S57 until the touch operation described above is accepted.

  By the way, prior to step S58, the image information identification unit 106 identifies attributes of image information. When it is identified that the image information is handwritten input as characters, the image information identification unit 106 supplies the image information to the image information processing unit 96 side. On the other hand, when the image information is identified as other image information (sound, text, symbol only), it is supplied to the annotation information storage unit 94 side. In addition, even if it is the image information written and input as a character, it may be made possible to select whether or not to perform an enlargement / reduction process described later on each image information.

  Next, the character size correction unit 112 corrects the image of the writing area 144 (step S58). Prior to the correction process, the character size calculation unit 110 separates and recognizes at least one character written in the writing region 144 and estimates the size of each character. As this separation / recognition technique, various known techniques (for example, a pattern matching method) related to image recognition processing can be applied. Hereinafter, an example of the separation / recognition method when the image of the writing area 144 is binary data will be described.

  As shown in FIG. 7A, the character size correction unit 112 performs a one-dimensional distribution of on-pixels (written pixels) with respect to an image of a writing area 144 (hereinafter referred to as a character image 150) input by writing as characters. (Or 2D distribution) trend is analyzed. Here, an image area in which off pixels (pixels not written) are continuous along the X direction is defined as a “margin area”. In the illustrated example, first to seventh blank areas 152a to 152g are detected. In this case, the character size correction unit 112 determines the character “N” as the first character from the difference value between the right end (X coordinate) of the first margin area 152a and the left end (X coordinate) of the second margin area 152b. Estimate the size. Similarly, the six character sizes are estimated.

  Then, the character size calculation unit 110 calculates an average value of the six estimated character sizes. In this figure, it is assumed that the proofreader intended to write the Roman numeral “II”, but the character size correction unit 112 recognizes that the Roman numeral “I” is two. In this case, the character size of “II” is estimated as about half the character size, unlike the prospective view. Therefore, by taking an average value of the estimated six character sizes, the above estimation error can be reduced. The character size calculation unit 110 may calculate not only the average value but also the statistical value including the mode value, the center value, the maximum value, and the minimum value.

  After that, the character size correction unit 112 corrects the character image 150 so as to match a predetermined character size. Specifically, the character size correction unit 112 cuts out an image so as to include all on-pixels based on the separation / recognition result of each character by the character size calculation unit 110, and acquires a trim image 154 (FIG. 7B). reference). Then, the character size correction unit 112 enlarges / reduces the trim image 154 at a predetermined enlargement / reduction rate. This enlargement / reduction ratio is determined by Cd / Cc when the character size Cc calculated by the character size calculation unit 110 and the predetermined character size Cd are used. Then, the character size correcting unit 112 acquires the corrected image 156 by rearranging the enlarged / reduced trim image 154 in an image area having the same size as the writing area 144 (FIG. 7C). Thereby, the variation in writing within the range of the writing area 144 can also be reduced.

  This correction can be applied even if the character string written in the writing area 144 is not only horizontally written but also vertically written. The same applies to writing over a plurality of lines as well as a single line.

  Next, the enlargement / reduction processing unit 108 enlarges / reduces the corrected image 156 (step S59). The enlargement / reduction processing unit 108 determines the enlargement / reduction ratio so that the size of the writing area 144 (that is, the area size of the corrected image 156) matches the size of the application area 140. Specifically, in order to convert K · Rd · Sx [pixel] to Sx [pixel] in the horizontal direction, the enlargement / reduction ratio may be set to 1 / (K · Rd). Since the aspect ratio before and after scaling is the same, the vertical scaling ratio is also {= 1 / (K · Rd)}. Thereby, it is possible to prevent the characters displayed in the adding area 140 from being distorted.

  Next, the display control unit 84 updates and displays the display screen 120 and displays the calibration image 122 to which new annotation information is added (step S60).

  As shown in FIG. 8, the window 146 (see FIG. 6B) is closed on the display screen 120, and image information (enlarged / reduced corrected image 156 s) is newly displayed at the position of the application area 140. Is done. In other words, in the giving area 140, the characters written in the writing area 144 are displayed while maintaining the similar relationship.

  Next, the writing information interpretation unit 90 determines whether or not an instruction to save the setting has been received (step S61). Specifically, the writing information interpretation unit 90 determines whether or not there is a touch operation on the third icon 130. If it is determined that there is no touch operation, the process returns to step S53, and steps S53 to S61 are repeated thereafter.

  For example, as shown in FIG. 9A, new annotation information (the same content as the previous time) is displayed for another application position 160 (above the application area 140) in a display state in which the display magnification Rd is higher than that in FIG. 6A. )). Then, as shown in FIG. 9B, a provision area 162 that is substantially the same size as the provision area 140 that has already been assigned is designated, and image information as characters (enlarged / reduced corrected image 164s) is specified in the provision area 162. Is newly displayed. That is, the relative size of the application area 140 (or another application area 160) with respect to the calibration image 122 is always constant. Further, the relative size can be maintained by further enlarging / reducing the corrected images 156s and 164s following the change of the display magnification Rd of the calibration image 122.

  Returning to FIG. 5, if it is determined in step S61 that the third icon 130 has been touched, the information processing apparatus 32a transmits the annotation information to the remote server 54 side (step S62). Specifically, the annotation information storage unit 94 temporarily stores image information as characters (enlarged / reduced corrected images 156 s and 164 s) and a given position 138 on the calibration image 122 as annotation information data.

  Then, the information processing apparatus 32a transmits the annotation information data to a predetermined destination (remote server 54) via the communication unit 80. The remote server 54 receives the annotation information data via the wireless LAN router 30, the LAN 20, the gateway 22, the network 18, and the gateway 52. The file server 70 stores the annotation information data in association with the calibration data.

  In this way, the proofreader electronically issues a correction data correction instruction (step S5).

  Returning to FIG. 4, the designer belonging to the production company 14 receives a notification mail from the mail server 72 to the effect that there has been a color correction instruction (step S <b> 6). For example, the designer terminal 38 (main unit 38 a) receives a notification mail from the mail server 72 via the network 18, the gateway 36, and the LAN 34.

  Next, the designer corrects the calibration data (step 7). Browsing the proofreading data together with the annotation information and confirming the content of the correction from the proofreader. In order to view the calibration image 122, either the designer terminal 38 or the information processing apparatus 44 may be used. As described above, even annotations with different proofreaders and different display magnifications Rd are displayed with substantially the same character size, so that it is particularly easy for a third party to see and the contents of the instructions can be easily confirmed.

  In this way, the designer terminal 38 creates corrected calibration data (re-calibration data) and transmits it to the remote server 54 side. Then, the remote server 54 receives the retraining data via the wireless LAN router 42, the LAN 34, the gateway 36, the network 18, and the gateway 52. Then, the file server 70 stores this review data.

  When correction by the designer is completed, the process returns to step S2 and the proofreader receives a notification mail from the remote server 54 (mail server 72) (step S2).

  Hereinafter, similarly, steps S2 to S7 are repeated to perform calibration work (re-schooling, re-schooling). If it is determined that there is no need for correction (that is, if all the proofreaders involved have notified the remote server 54 of an instruction to approve the contents of the page), the file server 70 stores the last updated proofreading data. Store as school completion data. For example, the print operator belonging to the printing company 16 receives a notification mail from the mail server 72 (step S8). The operator terminal 56 (main body 56a) receives a notification mail from the mail server 72 via the LAN 50.

  Next, the printing operator belonging to the printing company 16 produces the printed matter 64 based on the school completion data (step S9). Specifically, the print operator causes the DDCP 62 to print the proof 60 and performs calibration. Thereafter, a printing plate is prepared, and a printed matter 64 is produced using the offset printing machine 66.

  As described above, since the writing area size determining unit 98 that determines the size of the writing area 144 common to the image information to be written as characters is provided, it is the same as in the case where the range of the writing area 144 is not limited. Variation in writing of character size by different or different workers can be reduced. In addition, since the provision area size determination unit 100 that determines the size of the provision area 140 to which the image information is to be imparted is provided so as to be proportional to the display magnification Rd of the calibration image 122, the calibration image 122, the provision area 140, The relative size of is always constant. That is, the writing area in which the image information is input by writing so that the size of the writing area 144 determined by the writing area size determining section 98 matches the size of the applying area 140 determined by the applying area size determining section 100. By enlarging / reducing the 144 image, it is possible to suppress a variation in the character size due to a variation in writing by the operator and a difference in the display magnification Rd. Accordingly, it is possible to eliminate the difficulty of visually recognizing the annotation information and to easily confirm the instruction content.

  Next, a modification of the operation of the information processing apparatus 32a (applying annotation information) in step S5 will be described with reference to FIGS. 10A and 10B.

  As illustrated in FIG. 10A, when the operator wants to add annotation information to the end portion of the lead line 136 with a relatively large number of characters, the worker performs a predetermined operation (drag operation) using the touch pen 74. In response to this drag operation, the grant area designation unit 104 designates a grant area 170 (shown by a broken line) that is long in the horizontal direction, and the grant area size determination unit 100 determines the size of the grant area 170. . Then, the writing area size determination unit 98 determines the size of the writing area 172 having the same or similar shape as the application area 170. Then, the writing area specifying unit 102 specifies the writing area 172 according to the size determined by the writing area size determining unit 98.

  Then, as shown in the example of FIG. 10B, the window 146 including the writing area 172 is displayed so as to overlap the calibration image 122. In this case, since the writing area 172 is long in the horizontal direction, the operator can give annotation information with a relatively large number of characters.

  As described above, since the size of the writing area 172 having the same or similar shape as the determined application area 170 is determined, the operator corresponds to the shape (particularly the aspect ratio) of the application area 170. In the writing area 172, it is possible to input characters freely. Then, the image of the writing area 172 in which the image information is written and written is enlarged / reduced so that the determined size of the writing area 172 matches the size of the adding area 170, so that The arrangement state of characters can be maintained. Accordingly, it is possible to eliminate the difficulty of visually recognizing the annotation information and to easily confirm the instruction content.

  In addition, this invention is not limited to embodiment mentioned above, Of course, it can change freely in the range which does not deviate from the main point of this invention.

  For example, the client device (information processing device 32a or the like) according to the present embodiment is configured integrally with a main body, a display unit, and an input unit. The present invention can be applied even if it is composed of 24a, display unit 24b and input unit 24c).
