<First Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof is not repeated.

  With reference to FIG. 1, the image determination apparatus according to the present embodiment will be described. FIG. 1 is a configuration diagram of an image determination apparatus according to the present embodiment.

  The image determination apparatus according to the present embodiment determines whether or not the entire print prohibited image (output prohibited image) is included across the image represented by each of the plurality of image data. Then, when the determination result is affirmative, the image determination device processes and prints the image represented by the image data, and when the determination result is negative, the image determination device prints the image representing the image data without processing.

  One image data represents, for example, an image for one page. Printing is an example of image data output.

  The image determination apparatus according to the present embodiment is applied to an image forming apparatus (for example, a multifunction machine).

  As shown in FIG. 1, the image determination device 1 according to the present embodiment includes an image acquisition unit 2, a storage unit 3 (first storage unit, second storage unit), a display unit 4, and an operation input unit 5 ( 1st operation input part, 2nd operation input part), the printing part 6, and the control part 7 are provided.

  The image acquisition unit 2 acquires image data for printing. The image acquisition unit 2 is, for example, an image reading unit or a communication unit.

  The image reading unit has a document table. The image reading unit optically reads a document placed on a document table, and generates image data for printing based on the read information. When the image acquisition unit 2 is an image reading unit, the image acquisition unit 2 acquires image data for printing by generating image data for printing.

  The communication unit communicates with an external device (for example, a personal computer) by wired communication or wireless communication, and receives image data for printing from the external device. When the image acquisition unit 2 is a communication unit, the image acquisition unit 2 receives the image data for printing from the external device, and acquires the image data for printing.

  The storage unit 3 stores various data. The various data are, for example, image data for printing, print prohibited image data (output prohibited image data), user information, and identification information of print prohibited images. The print prohibition image data is image data representing a print prohibition image. The print prohibited image is an image for which printing is prohibited. The user information is information that identifies a user who uses the image determination apparatus 1, and is, for example, personal information of the user. The print prohibition image identification information is information for identifying a print prohibition image. The storage unit 3 is, for example, a nonvolatile storage device.

  The display unit 4 displays a preview of the image represented by the print image data. The display unit 4 is a liquid crystal display device, for example.

  Various operations are input to the operation input unit 5. The various operations are, for example, an operation for selecting an image processing method and an operation for inputting user information. The image processing method is a method of processing a part of an image represented by image data for printing so as to make it difficult to recognize a part of the image content.

  The printing unit 6 prints an image represented by image data for printing.

  The control unit 7 controls each unit of the image determination apparatus 1 (image acquisition unit 2, storage unit 3, display unit 4, operation input unit 5, and printing unit 6). The control unit 7 includes a determination unit 9, a determination unit 10 (first determination unit), a determination unit 11 (second determination unit), a storage control unit 12, a display control unit 13, an image processing unit 14, And a printing control unit 15.

  The control unit 7 includes, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The CPU executes a program stored in the ROM, for example, so that the CPU can control each unit of the control unit 7 (determination unit 9, determination unit 10, determination unit 11, storage control unit 12, display control unit 13, image processing unit 14, And it functions as the print control unit 15).

  The determination unit 9 determines whether the image represented by the image data includes the entire print prohibited image. The image data is image data for printing acquired by the image acquisition unit 2. Hereinafter, the entire image of the print prohibited image is also simply referred to as the entire image. Details of the determination method by the determination unit 9 will be described later with reference to FIG.

  The determination unit 10 determines whether the image represented by the image data includes a partial image of the print prohibited image. The image data is image data for printing acquired by the image acquisition unit 2. The partial image of the print prohibition image is a partial image of an arbitrary area of the print prohibition image. Hereinafter, the partial image of the print prohibited image is also simply referred to as a partial image. Details of the determination method by the determination unit 10 will be described later with reference to FIG.

  The determination unit 11 determines whether or not the entire image represented by each of the one or more image data includes the entire print-prohibited image. The one or more pieces of image data are image data determined by the determination unit 10 as including a partial image of the print prohibition image.

  That is, when there is only one image data, the determination unit 11 determines whether or not the image represented by one image data includes the entire print prohibited image. Further, when there are a plurality of image data, the determination unit 11 determines whether or not the entire image of the print prohibited image is included across the images represented by each of the plurality of image data. Details of the determination method by the determination unit 11 will be described later with reference to FIG.

  The storage control unit 12 controls the storage of various data in the storage unit 3. For example, the storage control unit 12 stores the image data acquired by the image acquisition unit 2 in the storage unit 3 as image data for printing or print prohibited image data.

  When an operation for saving as print-prohibited image data is input to the operation input unit 5, the storage control unit 12 stores the print image data acquired by the image acquisition unit 2 as print-prohibited image data. Save to. At that time, the storage control unit 12 adds the identification information of the print prohibition image to the print prohibition image data and stores it in the storage unit 3. The identification information of the print prohibition image is identification information for identifying the print prohibition image represented by the print prohibition image data.

  Accordingly, the user causes the image acquisition unit 2 to acquire the print prohibition image and saves the image data of the print prohibition image as the print prohibition image data in the storage unit 3. sign up.

  Further, when the determination result of the determination unit 11 is negative and the user information is input to the operation input unit 5, the storage control unit 12 associates the user information with the identification information of the print prohibited image and stores the user information. Save to. The identification information of the print prohibition image is information for identifying the print prohibition image included in the image data that is the target of the determination result of the determination unit 11.

  The display control unit 13 controls display on the display unit 4. When the determination result of the determination unit 11 is affirmative, the display control unit 13 displays an image represented by the target image data of the determination result on the display unit 4. The display control unit 13 highlights the partial image of the print prohibited image included in the image.

  The highlight display is a display for making it easier for the user to recognize which region of the image represented by the image data is a partial image. The highlight display is, for example, a display that surrounds the partial image with a thick line, or a display that enlarges the partial image.

  In addition, the display control unit 13 presents options for an image processing method for processing the partial image on the display unit 4. Options for the image processing method include, for example, whitening processing, black painting processing, and ruled line processing. The whiteout process is a process of displaying a part of an image with a single white color. The black filling process is a process of displaying a part of an image in black. The ruled line process is a process for making it difficult to recognize a part of the image contents by drawing a plurality of straight lines (for example, horizontal lines) on a part of the image.

  Moreover, the display control part 13 displays the message which prompts registration of user information on the display part 4, when the determination result of the determination part 11 is negative.

  Based on the image processing method selected by the input to the operation input unit 5, the image processing unit 14 processes the partial image of the print prohibited image included in the image represented by the image data.

  The print control unit 15 determines the determination result of the determination unit 9, the determination result of the determination unit 10, the determination result of the determination unit 11, whether or not user information is input to the operation input unit 5, and image processing to the operation input unit 5. The printing unit 6 is controlled based on whether or not a method selection operation is input. Details of the control by the print control unit 15 will be described later with reference to FIG.

  Next, the determination method of the determination unit 9 will be described in detail with reference to FIG. FIG. 2 is a diagram illustrating a determination method of the determination unit 9. Hereinafter, the image represented by the image data determined by the determination unit 9 is also referred to as a determination image G. FIG. 2A is a diagram illustrating an example of the entire print-prohibited image and the determination image. FIG. 2B is a diagram illustrating a determination method of the determination unit 9. The entire image G0 of the print prohibition image is superimposed on the determination image G shown in FIG.

  The determination unit 9 determines whether or not the image (determination image) G represented by the image data includes the entire print prohibited image G0. Hereinafter, this determination is also referred to as determination A.

  Specifically, as illustrated in FIG. 2B, the determination unit 9 superimposes the entire image G0 on the determination image G. The entire image G0 is smaller than the determination image G. Then, the determination unit 9 scans the entire image G0 over the entire region of the determination image G. Each time the entire image G0 is slightly moved on the determination image G, the determination unit 9 compares the entire image G0 and the image in the overlapping region Sa of the determination image G to calculate the degree of coincidence of the images. The overlapping area Sa is an area that overlaps the entire image G0 in the determination image G.

  The degree of coincidence of images is calculated as follows, for example. That is, the difference absolute value between the pixel value of the determination image G at the same pixel position and the pixel value of the entire image G0 is obtained at each pixel position in the overlapping region Sa. The image value is a luminance value. Then, the obtained absolute difference value is integrated over all the pixel positions in the superposition region Sa. The integrated difference absolute value is the degree of coincidence of images. That is, the smaller the calculated value of the degree of coincidence of images, the higher the degree of coincidence between the determination image G and the image in the overlapping area Sa.

  Then, the determination unit 9 determines that the entire image G0 and the image in the superimposed region Sa do not match when the matching degree of the images is equal to or greater than the first threshold value. On the other hand, when the degree of coincidence of the images is less than the first threshold value, the determination unit 9 determines that the entire image G0 and the image in the overlapping area Sa match.

  Then, when the overlapping region Sa determined to match the entire image G0 does not exist in the determination image G, the determination unit 9 denies determination A for the image data. On the other hand, when the overlapping region Sa determined to match the entire image G0 exists in the determination image G, the determination unit 9 affirms the determination A for the image data.

  Next, the determination method of the determination unit 10 will be described in detail with reference to FIG. FIG. 3 is a diagram illustrating a determination method of the determination unit 10. FIG. 3A is a diagram illustrating an example of the image G represented by the image data determined by the determination unit 10. Hereinafter, the image G is also referred to as a determination image G. FIG. 3B is a diagram showing an example of the entire print prohibited image G0. The area image gij is superimposed on the entire image G0 shown in FIG. The area image gij is one area image when the determination image G is divided into a plurality of area images.

  The determination unit 10 determines whether the image (determination image) G represented by the image data includes a partial image of the print prohibition image. Hereinafter, this determination is also referred to as determination B.

  Specifically, as illustrated in FIG. 3A, the determination unit 10 divides the determination image G into, for example, a lattice shape, thereby dividing the determination image G into a plurality of area images gij (i = 1, 2,..., J = 1, 2, ...).

  The area image gij indicates an area image in the i-th row and j-th column among a plurality of area images arranged in a grid pattern. Each of the plurality of area images gij is smaller than the entire image G0.

  Then, the determination unit 10 superimposes the area images gij one by one on the entire image G0. Then, the determination unit 10 moves the area image gij little by little on the entire image G0, and scans the area image gij over the entire area of the entire image G0. Every time the section image gij is slightly moved on the entire image G0, the determination unit 10 compares the section image gij with the image in the overlapping region Sb of the entire image G0 (that is, a part of the entire image G0) The degree of coincidence of is calculated. The overlapping area Sb is an area that overlaps the area image gij in the entire image G0. The image coincidence calculation method is the same as the image coincidence calculation method in the determination unit 9.

  Then, the determination unit 10 determines that the area image gij and the image in the superimposed region Sb do not match when the degree of coincidence of the images is equal to or greater than the second threshold. On the other hand, when the degree of coincidence of the images is less than the second threshold value, the determination unit 10 determines that the area image gij and the image in the superimposed region Sb match.

  Then, when the section image gij determined to match the image in the superimposed area Sb does not exist in the plurality of section images gij, the determination unit 10 determines that the determination B for the image data is negative. On the other hand, when the section image gij determined to match the image in the superimposed region Sb exists in the plurality of section images gij, the determination unit 10 determines that the determination B for the image data is positive.

  Of the images represented by the image data, the area image gij determined by the determination unit 10 as being coincident with the image in the superimposed region Sb is a region including a partial image of the print prohibited image.

  Next, the determination method of the determination unit 11 will be described in detail with reference to FIG. FIG. 4 is a diagram illustrating an example of a combined image. The combined image KG is an image obtained by combining the images G represented by one or more pieces of image data. The combined image KG shown in FIG. 4 is overlaid with the entire print prohibited image G0.

  The determination unit 11 determines whether the entire image G represented by each of the one or more image data includes the entire print prohibited image G0. Hereinafter, this determination is also referred to as determination C. The one or more pieces of image data are image data that the determination unit 10 determines to include a partial image of the print prohibited image.

  Specifically, the determination unit 11 performs determination C as follows. The determination unit 11 first calculates a combination of arrays of images G represented by one or more pieces of image data. FIG. 4 shows an example of the arrangement of the images G when there are four images G (G1, G2, G3, G4). The four images G shown in FIG. 4 are arranged in 2 rows and 2 columns.

  The combination of the arrangements of one or more images G includes an arrangement in which the images G are arranged in a horizontal example, an arrangement in which the images G are arranged in a vertical row, and an arrangement in which the images G are arranged in a vertical and horizontal manner. The combination of the arrangement of one or more images G includes an arrangement in which each image G is inverted vertically, inverted horizontally, rotated 90 degrees, and rotated 180 degrees.

  Then, the determination unit 11 generates a combined image KG by combining the images G represented by each of the one or more pieces of image data into one image based on each of the calculated array combinations. Then, the determination unit 11 determines whether or not the generated combined image KG includes the entire image G0. Hereinafter, this determination is also referred to as determination D. When there is only one image data, the combined image KG is an image represented by one image data.

  Specifically, the determination unit 11 performs determination D as described below. First, as illustrated in FIG. 4, the determination unit 11 generates one combined image KG based on one array among combinations of arrays of images G. Then, the determination unit 11 superimposes the entire image G0 on the generated combined image KG. Then, the determination unit 11 scans the entire image G0 over the entire region of the combined image KG. Each time the entire image G0 is slightly moved on the combined image KG, the determination unit 11 compares the entire image G0 with the image in the overlapping region Sc of the combined image KG and calculates the degree of coincidence of the images. The overlapping area Sc is an area that overlaps the entire image G0 in the combined image KG. The image coincidence calculation method is the same as the image coincidence calculation method in the determination unit 9.

  And the determination part 11 determines with the whole image G0 and the image in the superimposition area | region Sc not matching, when the matching degree of an image is more than a 3rd threshold value. On the other hand, when the degree of coincidence of the images is less than the third threshold value, the determination unit 11 determines that the entire image G0 and the image in the overlapping area Sc match.

  Then, when the overlapping region Sc determined to match the entire image G0 does not exist in the combined image KG, the determination unit 11 negates the determination D for one combined image KG (that is, one array) (that is, the combined image). KG does not include the entire image G0). On the other hand, when the overlapping region Sc determined to match the entire image G0 is present in the combined image KG, the determination unit 11 determines that the determination D for one combined image KG is affirmative (that is, the combined image KG indicates the entire image G0). Included).

  Then, the determination unit 11 performs determination D for all the combinations of the arrays of the images G. Then, the determination unit 11 determines one or more pieces of image data when the array determined to be affirmative in the determination D (that is, the combined image KG includes the entire image G0) does not exist in the calculated combination of arrays. It is determined that the determination C is negative. On the other hand, the determination unit 11 determines that the determination C for one or more pieces of image data is affirmative when the array determined to be affirmative in the determination D exists in the calculated combination of arrays.

  Next, the operation of the image determination apparatus 1 will be described with reference to FIG. FIG. 5 is a flowchart showing the operation of the image determination apparatus 1.

  In step S1, the image acquisition unit 2 acquires one piece of image data for printing.

  In step S <b> 2, the determination unit 9 determines whether or not the image represented by one image data includes the entire print-prohibited image. If the determination result is affirmative (YES), the operation proceeds to step S3, and if the determination result is negative (NO), the operation proceeds to step S4.

  In step S3, the print control unit 15 stops printing an image represented by one image data. Then, the operation ends.

  In step S4, the determination unit 10 determines whether or not the image represented by one image data includes a partial image of the print prohibited image. The print prohibited image is a print prohibited image represented by the print prohibited image data stored in the storage unit 3. If the determination result is negative (NO), the operation proceeds to step S5. If the determination result is affirmative (YES), the operation proceeds to step S6.

  In step S5, the print control unit 15 prints an image represented by one image data. Therefore, when the image represented by one image data does not include the entire image and the partial image of the print prohibition image, the image represented by the one image data is printed. Then, the operation ends.

  In step S <b> 6, the storage control unit 12 stores one image data in the storage unit 3. One image data is an image that does not include the entire print-prohibited image and that includes a partial image of the print-prohibited image. Accordingly, when the image acquisition unit 2 sequentially acquires one or more pieces of image data in step S1, predetermined image data among the one or more pieces of image data is accumulated and stored in the storage unit 3 in step S6. The predetermined image data represents an image that does not include the entire print prohibited image and includes a partial image of the print prohibited image. Then, the operation proceeds to step S7.

  In step S <b> 7, the determination unit 11 determines whether or not the next image data has been acquired before a predetermined time has elapsed since the time when the image acquisition unit 2 acquired the one image data. If the determination result is affirmative (YES), the operation returns to step S2, and the operations after step S2 are repeated for the next one image data. On the other hand, when the determination result is negative (NO), the operation proceeds to step S8.

  In step S8, the determination unit 11 determines whether or not the entire image represented by each of the one or more pieces of image data includes the entire print-prohibited image. One or more pieces of image data are image data accumulated and stored in the storage unit 3 in step S6. If the determination result is affirmative (YES), the operation proceeds to step S9. If the determination result is negative (NO), the operation proceeds to step S12.

  In step S <b> 9, the display control unit 13 displays an image represented by each of the one or more image data on the display unit 4. The display control unit 13 highlights the partial image of the print prohibited image included in the image. Further, the display control unit 13 presents options for the image processing method on the display unit 4. The image processing method is a method of processing a partial image of a print prohibited image included in an image. Then, the operation proceeds to step S10.

  In step S <b> 10, when the user does not input an operation for selecting an image processing method option to the operation input unit 5 within a predetermined time from when the image processing method option is displayed on the display unit 4 (NO), Operation proceeds to step S3. In step S3, the print control unit 15 stops printing the image represented by the one or more image data. Then, the operation ends.

  On the other hand, in step S10, when the user inputs an operation for selecting an image processing method option to the operation input unit 5 within a predetermined time from when the image processing method option is displayed on the display unit 4 (YES). The operation proceeds to step S11.

  In step S11, the image processing unit 14 processes a partial image of the print prohibited image included in each of the one or more image data based on the selected image processing method. As a result, the partial image of the print prohibition image included in one or more image data is difficult to be recognized. Then, the operation proceeds to step S5. In step S5, the print control unit 15 prints an image represented by each of the one or more image data. Then, the operation ends.

  On the other hand, in step S12, the display control unit 13 displays a message prompting the registration of user information on the display unit 4. Then, the operation proceeds to step S13.

  In step S13, if the user does not input his / her user information to the operation input unit 5 within a predetermined time from when the message is displayed on the display unit 4 (NO), the operation proceeds to step S3. In step S3, the print control unit 15 stops printing the image represented by each of the one or more pieces of image data. Then, the operation ends.

  On the other hand, if the user inputs his / her user information to the operation input unit 5 within a certain time from the time when the message is displayed on the display unit 4 in step S13 (YES), the operation proceeds to step S14.

  In step S <b> 14, the storage control unit 12 stores the user information input to the operation input unit 5 in the storage unit 3 in association with the identification information of the print prohibition image. The identification information of the print prohibition image is information for identifying the print prohibition image included in the image represented by each of the one or more image data. By referring to the stored user information and identification information of the print prohibition image, it is possible to confirm who printed which print prohibition image. Then, the operation proceeds to step S5. In step S5, the print control unit 15 prints an image represented by each of the one or more image data. Then, the operation ends.

  As described with reference to FIG. 5, in the above operation, when one image data includes the entire print-prohibited image, the one image data is not printed (steps S 1 → S 2 → S 3). If the one image data does not include the entire image and the partial image of the print prohibition image, the one image data is printed (steps S 1 → S 2 → S 4 → S 5).

  Further, when each of the one or more image data includes a partial image of the print prohibition image and the entire image of the print prohibition image is included in the entire one or more image data, if the partial image is processed, One or more pieces of image data are printed (steps S8 → S9 → S10 → S11 → S5). On the other hand, if the partial image is not processed, one or more pieces of image data are not printed (steps S8 → S9 → S10 → S3).

  If each of the one or more image data includes a partial image of the print prohibition image and the entire image of the print prohibition image is not included in the whole of the one or more image data, if the user registration is performed, 1 One or more pieces of image data are printed (steps S8 → S12 → S13 → S14 → S5). On the other hand, if the user is not registered, one or more pieces of image data are not printed (steps S8 → S12 → S13 → S3).

<Modification>
In the first embodiment, the determination unit 11 performs determination C when the next image data is not acquired before the predetermined time has elapsed from the time when the image acquisition unit 2 acquired the one image data (step S8). NO), the timing at which the determination unit 11 performs the determination C is not limited in this way. For example, when all the partial images necessary for constituting the entire image of the print prohibition image are prepared among the partial images of the print prohibition image included in the image data accumulated and stored in the storage unit 3 in step S6, The determination unit 11 may perform determination C.

Second Embodiment
A second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a diagram illustrating a determination method of the determination unit 11 according to the present embodiment.

  In the first embodiment, when the determination unit 10 determines that the image represented by the image data includes a partial image of the print prohibition image, the image data is accumulated and stored in the storage unit 3 (step S6 in FIG. 6). In the embodiment, the determination unit 10 accumulates and saves area data in the storage unit 3 instead of image data. The area data represents which area of the print prohibited image the partial image is. The area data is represented using, for example, a coordinate system defined on the print prohibited image.

  The area data has a smaller data amount than the image data. Therefore, the storage capacity of the storage unit 3 can be saved by storing the area data in the storage unit 3 instead of the image data. The area data may be compressed and stored. The storage capacity of the storage unit 3 can be further saved.

  The determination unit 11 of the present embodiment performs the above determination C using region data instead of image data. Specifically, the determination unit 11 generates a joint region by joining regions represented by one or more region data accumulated and stored in the storage unit 3. When there is only one area data accumulated and stored in the storage unit 3, the area represented by one area data is a joint area. Then, the determination unit 11 calculates the occupancy ratio of the joint area with respect to the entire image of the print prohibited image.

  Specifically, when, for example, two area data D1 and D2 are accumulated and stored in the storage unit 3, the determination unit 11 calculates the occupation ratio Q as follows. For example, as shown in FIG. 6, the area data D1 represents the area R1 of the entire image G0, and the area data D2 represents the area R2 of the entire image G0. The determination unit 11 joins the region R1 and the region R2 to generate a joint region Rs.

  And the determination part 11 calculates the area of each of the whole image G0 and the joining area | region Rs, and calculates the occupation rate Q of the joining area | region Rs with respect to the whole image G0 based on the calculated area. The area of the entire image G0 is calculated based on the print prohibition image data, and the area of the joining region Rs is calculated based on the region data D1 and the region data D2.

  Then, the determination unit 11 determines that the determination C is affirmative when the occupation ratio is greater than or equal to a certain value, and determines that the determination C is negative when the occupation ratio is less than the certain value.

  In the present embodiment, since image data is not stored, the operation using the image data (steps S9, S11, and S5) is not performed in the operation illustrated in FIG. The configuration and operation of this embodiment are the same as the configuration and operation of the first embodiment except for the above points.

<Third Embodiment>
In the second embodiment, the area data is accumulated and stored in the storage unit 3 instead of the image data.
