Description

  The present invention relates to an image processing apparatus and an image processing system.

Conventionally, when an image processing apparatus such as a personal computer synthesizes and outputs a plurality of images and causes an image forming apparatus such as a printer to perform overlay printing, the overlay image is printed on the near side or the background side of the target image. It has become. In overlay printing, when the character in the target image and the overlay image overlap, or when the target image and the character in the overlay image overlap, the image processing apparatus determines whether the character is distinguishable and easy to understand. The process of filling the surrounding area is performed, but if the area around the character is filled with white, the background image may be erased. In view of this, an image processing apparatus has been proposed that adds processing for preventing the background of a character from being filled with white in order to avoid erasing the background image in overlay printing (see, for example, Patent Document 1). ).

The input second image is transferred to the mask processing unit 35 and subjected to mask calculation processing. The transparency setting unit 32 is a functional unit for setting the presence / absence of transparency and the transmittance using the input device 11 such as a keyboard and a mouse in the setting screen of the printer driver 30. The set presence / absence of transmission and the transmittance are transferred to the mask data selection unit 34. Further, the image mask storage unit 33 stores at least one image mask data having transparency. Further, the mask data selection unit 34 refers to the image mask data from the image mask storage unit 33 in accordance with the setting of the transmission setting unit 32 and passes it to the mask processing unit 35. Further, the mask processing unit 35 performs mask calculation processing on the image mask data and the second image. The calculated data is stored in the storage unit 40.

  The first image storage unit 36 stores the print data output from the application 20 and passes the print data to the control unit 37 in accordance with an instruction from the control unit 37. The control unit 37 manages the entire printing. The translation unit 38 translates the print data transferred from the control unit 37 into a printer language and returns the print data to the control unit 37. The control unit 37 passes the translated print data to the communication control unit 39. Then, the communication control unit 39 transmits the translated print data to the printer 50. The storage unit 40 passes the stored second image data that has been subjected to the calculation process to the control unit 37 in accordance with an instruction from the control unit 37. The control unit 37 causes the translation unit 38 to translate the second image data that has been subjected to the calculation process, and passes the second image data translated into the printer language to the communication control unit 39.

  The printer 50 may be of any type of printing system such as an ink jet system, an electrophotographic system, or a thermal transfer system, or may be a multifunction machine having functions such as a facsimile, a copying machine, and a scanner. A monochrome printer that prints a monochrome image or a color printer that prints a color image may be used.

  The printer 50 includes a communication control unit 51, a control unit 52, a storage unit 53, an image forming unit 54, and a printing unit 55 as shown in the figure from the viewpoint of functions.

  The communication control unit 51 receives the print data that has been translated into the printer language and transmitted from the client computer 10. The control unit 52 manages the entire printing process. The storage unit 53 caches the received print data as necessary. Further, the image forming unit 54 converts the translated print data received from the client computer 10 into a bitmap image and passes it to the printing unit 55. The printing unit 55 prints the bitmap image converted by the image forming unit 54.

  Next, the operation of the image processing system 60 having the above configuration will be described. Here, in order to superimpose the second image as the foreground image on the first image as the background image so that both the two images can be seen, it is necessary to process the second image in advance. First, a method for generating the second image will be described.

  FIG. 2 is a diagram showing an example of a second image in the first embodiment of the present invention, FIG. 3 is a diagram showing an example of mask data in the first embodiment of the present invention, and FIG. FIG. 5 is a diagram showing an example of a calculated second image in the first embodiment, and FIG. 5 is a flowchart showing an operation of generating data of the second image in the first embodiment of the present invention.

  First, the user uses the input device 11 to input an image such as a watermark as the second image at the second image input unit 31 of the printer driver 30. The input second image may be in any format such as characters, images, bitmap image data, and the like. Here, it is assumed that the second image as shown in FIG. 2 is input.

  Next, using the input device 11, the user uses the transmission setting unit 32 of the printer driver 30 to input and set the transmission / non-transmission of the second image and the transmittance. Then, the mask data selection unit 34 refers to the image mask storage unit 33 to determine whether or not the set transmittance matches the transmittance of the mask data stored in the image mask storage unit 33. . Here, since the number of mask data stored in the image mask storage unit 33 is limited, if the transmittances do not match, the mask data having the closest transmittance is selected from the image mask storage unit 33 and read out. If the transmittances match, mask data having the matching transmittance is selected from the image mask storage unit 33 and read. Here, it is assumed that the mask data as shown in FIG. 3 has been read.

  Subsequently, the mask processing unit 35 generates a masked drawing space using the selected mask data, that is, creates a second image drawing space. The drawing space has a characteristic that if a bit set on a certain coordinate is 1, the data drawn on the coordinate is drawn as it is, and if the bit is 0, the drawn data is clipped. Shall. Then, the mask processing unit 35 reads the second image from the second image input unit 31. In addition, the mask processing unit 35 draws the data of the second image read from the second image input unit 31 in the masked drawing space, and performs arithmetic processing on the clipped second image. When the bit set on a certain coordinate is 1, the clipped second image data is drawn on the coordinate, and in the case of 0, it inherits the characteristic that nothing is drawn. FIG. 4 shows an example of a second image that has been subjected to arithmetic processing.

  Subsequently, the mask processing unit 35 generates and assigns an identification ID managed together with the data of the second image that has been subjected to the arithmetic processing. And the memory | storage part 40 preserve | saves the data of the 2nd image calculated by the mask process part 35, and produced | generated identification ID.

  Here, an example in which the calculation process of the second image is performed by the client computer 10 has been described. However, a procedure for executing the same process may be generated by the client computer 10 and the actual calculation process may be executed by the printer 50. Good.

Next, a flowchart will be described.
Step S1: Input a second image.
Step S2: Input the transmittance.
Step S3: Refer to the mask data to determine whether or not they match. The mask data is referred to, and if they match, the process proceeds to step S4. If the mask data is not matched, the process proceeds to step S5.
Step S4: Read the matched mask data from the image mask storage unit 33.
Step S5: Read the closest mask data from the image mask storage unit 33.
Step S6: A second image drawing space is created.
Step S7: The second image data is read.
Step S8: The second image data is calculated.
Step S9: An identification ID is assigned.
Step S10: The calculated second image data and identification ID are stored in the storage unit 40, and the process ends.

  Next, an operation for transmitting print data from the application 20 will be described.

  FIG. 6 is a flowchart showing an operation of transmitting print data according to the first embodiment of the present invention.

  First, arbitrary print data is created by the application 20 and printing is designated. The generated print data is stored as first image data in the first image storage unit 36 of the printer driver 30, and the first image storage unit 36 passes the print data to the control unit 37 as it is. Then, the control unit 37 passes the print data delivered from the first image storage unit 36 to the translation unit 38 to translate it into a printer language, and passes the translated print data to the communication control unit 39 via the control unit 37. . The communication control unit 39 transmits the translated print data to the printer 50.

  Subsequently, it is checked whether or not there is an overlay request for the second image designated by the user in the second image input unit 31 of the printer driver 30 before the printing instruction, that is, whether or not the second image is to be printed is determined. . If the second image is not printed, the printing process is terminated. When the second image is printed, the second image data generated by the mask processing unit 35 is transferred to the translation unit 38 to be translated into a printer language, and the translated second image data and the identification ID are controlled. The data is transferred to the communication control unit 39 via the unit 37. The communication control unit 39 transmits the translated second image data to the printer 50 and ends the process.

Next, a flowchart will be described.
Step S21 Arbitrary print data is created by the application 20, and printing is designated.
Step S22: The print data is translated and transmitted to the printer 50.
Step S23: Whether or not to print the second image is determined. If the second image is to be printed, the process proceeds to step S24. If the second image is not to be printed, the process is terminated.
Step S24: The second image data is translated and transmitted to the printer 50, and the process is terminated.

  Next, the operation of the image composition process will be described.

  FIG. 7 is a flowchart showing the image composition processing operation of the printer according to the first embodiment of the present invention.

  First, the communication control unit 51 of the printer 50 receives print data transmitted from the client computer 10 and translated, that is, translation data of the first image, and passes it to the control unit 52. Then, the control unit 52 passes the received translation data of the first image to the image forming unit 54. The image forming unit 54 performs a first image drawing process by editing the translation data of the first image into an image.

  Subsequently, it is checked whether or not the second image data is received. If the second image data is not received, the printing unit 55 prints the first image and ends the process. Further, when the second image data is received, it is checked whether there is an image obtained by editing the second image previously from the identification ID given to the second image. The edited image as the second image having the same identification ID is read out from the storage unit 53. If the image data does not exist, the second image rendering process is performed by editing the received translation data of the second image into image data by the image forming unit 54 and is stored in the storage unit 53 together with the identification ID.

  Subsequently, the second image data read from the storage unit 53 or the second image data edited by the image forming unit 54 is overlaid on the first image to be combined, and the printing unit 55 Printing is performed at.

  Thus, by storing the second image data generated on the storage unit 53 as the memory of the printer 50 in the storage unit 53, the next time the same data is printed, the calculation is performed again. It can be reused and can be printed efficiently.

  The image computation processing such as transparency and composition in the present embodiment is performed on the client computer 10 side based on the amount of image data, the communication speed between the client computer 10 and the printer 50, the time of the image computation processing itself, and the like. It may be determined as appropriate whether it is executed on the printer 50 or on the printer 50 side. In other words, if the amount of image data is large and this communication (transfer) takes time, it is advantageous to perform processing on the client computer 10 side, and the calculation processing time is longer than the transfer time. The client computer 10 or the printer 50 may be selected and executed, whichever is faster.

Next, a flowchart will be described.
Step S31: A first image drawing process is performed.
Step S32: to judge whether the second image has been received. When the second image is received, the process proceeds to step S33, and when the second image is not received, the process proceeds to step S38.
Step S33: It is determined whether an edited second image exists. When the edited second image exists, the process proceeds to step S36, and when the edited second image does not exist, the process proceeds to step S34.
Step S34: A second image drawing process is performed.
Step S35: The identification ID and the second image are stored.
Step S36: The second image having the same identification ID is read out.
Step S37: An arithmetic process for superposing and combining the second image with the first image is performed.
Step S38: Printing is performed and the process is terminated.

  As described above, in the present embodiment, the first image serving as the background image is synthesized with the second image serving as the foreground image, and then combined with the first image serving as the background image. Both the image and the second image can be printed so that they can be seen.

  Next, a second embodiment of the present invention will be described. In addition, about what has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol. The description of the same operation and the same effect as those of the first embodiment is also omitted.

  FIG. 8 is a block diagram showing a functional configuration of the image processing system according to the second embodiment of the present invention.

  As shown in FIG. 8, the printer driver 30 according to the present embodiment includes a third image input unit 41, a second third image composition unit 42 as a composition unit, and a second image transmission setting unit 43 as a transmission setting unit. And a third image transparency setting unit 44. Here, the third image input unit 41 is a functional unit that inputs a third image such as a watermark using the input device 11 such as a keyboard and a mouse in the setting screen of the printer driver 30. The input third image is transferred to the mask processing unit 35 and subjected to mask calculation processing. Then, the second image transparency setting unit 43 and the third image transparency setting unit 44 use the input device 11 such as a keyboard and a mouse within the setting screen of the printer driver 30 to set the presence / absence of transparency and the transmittance. It is a functional part. The set presence / absence of transmission and the transmittance are transferred to the mask data selection unit 34.

  Since other configurations and functions are the same as those in the first embodiment, description thereof will be omitted. The third image may be a watermark, or may be a form or letterhead.

  Next, the operation of the image processing system 60 having the above configuration will be described. Here, in order to superimpose the second image and the third image on the first image so that all three images can be seen, it is necessary to process and combine the second image and the third image in advance. is there. Therefore, the operation of the synthesis process of the second image and the third image will be described.

  FIG. 9 is a first flowchart showing the operation of the composition processing of the second image and the third image in the second embodiment of the present invention, and FIG. 10 is the second image and the second image in the second embodiment of the present invention. It is a 2nd flowchart which shows operation | movement of the synthetic | combination process of 3 images.

  First, the user uses the input device 11 to input a second image as an image such as a watermark using the second image input unit 31 of the printer driver 30. The input second image may be in any format such as characters, images, bitmap image data, and the like.

  Next, using the input device 11, the user uses the second image transparency setting unit 43 of the printer driver 30 to input and set the presence / absence and transparency of the second image. Then, the mask data selection unit 34 refers to the image mask storage unit 33 to determine whether or not the set transmittance matches the transmittance of the mask data stored in the image mask storage unit 33. . Here, since the number of mask data stored in the image mask storage unit 33 is limited, if the transmittances do not match, the mask data having the closest transmittance is selected from the image mask storage unit 33 and read out. If the transmittances match, mask data having the matching transmittance is selected from the image mask storage unit 33 and read. Here, it is assumed that the mask data as shown in FIG. 3 has been read.

  Subsequently, the user uses the input device 11 to input a third image as an image such as a watermark using the third image input unit 41 of the printer driver 30.

  Next, using the input device 11, the user uses the third image transparency setting unit 44 of the printer driver 30 to input and set the presence / absence and transparency of the third image. Then, the mask data selection unit 34 refers to the image mask storage unit 33 to determine whether or not the set transmittance matches the transmittance of the mask data stored in the image mask storage unit 33. . Here, since the number of mask data stored in the image mask storage unit 33 is limited, if the transmittances do not match, the mask data having the closest transmittance is selected from the image mask storage unit 33 and read out. If the transmittances match, mask data having the matching transmittance is selected from the image mask storage unit 33 and read.

  Subsequently, the interference rate of the mask data selected for the second image and the third image is calculated. For example, if the transmittance of the mask data selected for the second image and the third image is the same and the same mask data is selected, the interference rate of the two mask data is 100 [%]. . In this case, when the second image and the third image are overlapped, one of the lower images may not be visible.

  Therefore, it is determined whether or not the interference rate of the mask data selected for the second image and the third image is equal to or less than a predefined value. The defined value may be registered in the storage unit 40 of the printer driver 30 as a fixed value, or may be changed by the user. If the interference rate is larger than the defined value, the mask data selected for the second image and the third image is shifted, and the interference rate of the mask data is calculated again. In this way, the mask data is adjusted so that the interference rate of the mask data selected for the second image and the third image is smaller than the defined value.

  When the interference rate is smaller than the defined value, the mask processing unit 35 generates a masked drawing space using the mask data selected for the second image, that is, the second image drawing space. Create. The drawing space has a characteristic that if a bit set on a certain coordinate is 1, the data drawn on the coordinate is drawn as it is, and if the bit is 0, the drawn data is clipped. Shall. Then, the mask processing unit 35 reads the second image from the second image input unit 31. Further, the mask processing unit 35 draws the second image read from the second image input unit 31 in the masked drawing space, and performs arithmetic processing on the clipped second image. When the bit set on a certain coordinate is 1, the clipped second image data is drawn on the coordinate, and in the case of 0, it inherits the characteristic that nothing is drawn.

  Subsequently, the mask processing unit 35 generates a masked drawing space using the mask data selected for the third image, that is, creates a third image drawing space. The drawing space has a characteristic that if a bit set on a certain coordinate is 1, the data drawn on the coordinate is drawn as it is, and if the bit is 0, the drawn data is clipped. Shall. Then, the mask processing unit 35 reads out the third image from the third image input unit 41. Further, the mask processing unit 35 draws the third image read from the third image input unit 41 in the masked drawing space, and performs arithmetic processing on the clipped third image. Similarly to the second image data, the clipped third image data is drawn on the coordinates when the bit set on a certain coordinate is 1, and nothing is drawn when the bit is 0. It inherits the characteristics. Then, the mask processing unit 35 passes the two calculated images to the second and third image composition unit 42.

  Subsequently, the second third image combining unit 42 combines the calculated second image and the calculated third image to generate one clipped image, and returns the image to the mask processing unit 35. Then, the mask processing unit 35 generates and assigns an identification ID that is managed together with the arithmetically processed image. In addition, the storage unit 40 stores the image data calculated by the mask processing unit 35 and the generated identification ID.

  Here, an example in which the client computer 10 performs the calculation process and the synthesis process of the second image and the third image has been described. However, a procedure for executing the same process is generated by the client computer 10, and the actual calculation process is performed by the printer 50. May be executed.

  Further, the operation of transmitting print data from the application 20 and the operation of the image composition processing of the printer 50 are the same as those in the first embodiment, and a description thereof will be omitted.
