  An embodiment of the present invention will be described below by taking a multilayer display device (MLD device) as an example.

  FIG. 1 is a block diagram relating to the configuration of the MLD apparatus. As shown in the figure, the MLD apparatus 1 includes a print information output interface 11, a first display screen 12, a second display screen 13, a third display screen 14, a backlight 15, a print control unit 16, a display control unit 17, A CPU [Central Processing Unit] 18, operation buttons 19, a built-in memory 20, an image information input unit 21, and an image information input interface 22 are provided.

  FIG. 2 is a cross-sectional view of the MLD apparatus 1 when a plane parallel to the observation direction of the user (observer) is taken as a cross section. As shown in the figure, the MLD apparatus 1 includes a first display screen 12, a second display screen 13, a third display on a housing 10 that is open on the front side (in this application, means a side close to the observer). The display screen 14 and the backlight 15 are arranged in order from the near side to the far side.

  In this way, the display screens (12 to 14) are arranged in layers with the direction from the near side to the far side as the layer direction. In this embodiment, the display screen has three layers. However, the display screen may have two layers or four layers or more.

  The print information output interface 11 is provided with an external connection terminal and the like, and the printing apparatus 2 as an external device is detachably connected. The print information output interface 11 functions as an interface used when outputting print information to the printing apparatus 2.

  Note that the printing apparatus 2 is, for example, a general-purpose printer, and prints acquired print information (information for specifying the contents of printing, such as image information) on a printing paper supplied in advance. When connected to the MLD apparatus 1, the printing apparatus 2 receives print information from the MLD apparatus 1, and prints the received print information.

  Each of the first to third display screens (12 to 14) is formed as a liquid crystal display having pixels of the same size, each of which has RGB (red, green, and blue) pixels arranged on the entire surface. . The display control unit 17 adjusts the degree of light transmission for each pixel on each display screen (12 to 14). Thereby, in each display screen (12-14), an image is formed by the light emitted toward the near side from the backlight 15.

  The backlight 15 functions as a light source of the MLD apparatus 1 and is formed by, for example, a fluorescent tube or an LED [Light Emitting Diode]. The backlight 15 is controlled so as to continuously emit white light during a period in which an image is to be displayed on each display screen (12 to 14).

  The print control unit 16 can communicate with the printing apparatus 2 via the print information output interface 11, and transmits print information to the printing apparatus 2 in accordance with an instruction from the CPU 18. Note that what kind of information is adopted as print information will be apparent from the following description.

  Based on the image information transmitted from the built-in memory 20, the image information input unit 21 or the like, the display control unit 17 forms each display screen (12 to 12) so that an image is formed on each display screen (12 to 14). The degree of light transmission of each pixel provided in 14) is adjusted. The format of the image information used in the MLD apparatus 1 will be described again.

  The functional units of the print control unit 16 and the display control unit 17 may be realized by separate devices or may be realized by the same device. Further, the CPU 18 may have the functions of the print control unit 16 and the display control unit 17.

  The CPU 18 appropriately controls each unit of the MLD apparatus 1 so that the functions of the MLD apparatus 1 are exhibited (so that necessary operations are appropriately performed). The contents of main operations executed in the MLD apparatus 1 will be described in detail again.

  The operation button 19 includes a plurality of button switches (for example, push button switches) operated by the user, and is provided at a position where the user can operate. The user's operation content on the operation button 19 is transmitted to the CPU 18 and is reflected in various operations of the MLD apparatus 1.

  The built-in memory 20 is formed by a rewritable nonvolatile memory, a RAM used as a working memory, or the like, and stores image information and the like. The image information input unit 21 receives image information from the outside via the image information input interface 22. The input image information is temporarily recorded in the built-in memory 20, for example.

[Main operations performed by the MLD device]
Next, contents of main operations performed by the MLD apparatus 1 will be described.

  The MLD apparatus 1 performs an operation of generating print information according to a user operation and transmitting it to the printing apparatus 2 while displaying an image on each display screen (12 to 14). The flow of the operation will be described in more detail with reference to the flowcharts shown in FIGS. First, the overall flow of the operation will be described with reference to the flowchart shown in FIG.

  The MLD apparatus 1 normally accepts a user designation (for example, a designation of a file name attached to the image information) for an image to be displayed among the image information stored in the built-in memory 20. When the designation is made, the CPU 18 identifies the designated image information as display target image information (step S1). The identified image information is read into a work memory, for example, and used for subsequent operations.

  Here, the image information handled in the MLD device 1 includes first original image information that is information of an image displayed on the first display device 12 and second original that is information of an image displayed on the second display device 13. Image information and third original image information which is information of an image displayed on the third display device 14 are included. The term “original image information” is defined for convenience in order to distinguish it from “corrected image information” that appears later.

  In addition, in the images according to the first to third original image information, one or a plurality of foregrounds (those having an outline of some shape) are arranged in a blank space in the frame corresponding to the frame of the display screen. It has become. That is, the area excluding the foreground in the frame is blank. The foreground is also provided with color information, and when displayed on the display screen, the foreground is displayed in that color.

  When the original image is displayed on the display screen, the area corresponding to the blank is completely transparent (that is, the display state on the far side can be seen through as it is). Each original image information is information that specifies at least the shape, orientation, color, and position of each foreground.

  FIG. 5 shows specific examples of the first original image information ORG-1, the second original image information ORG-2, and the third original image information ORG-3. When these images are displayed on the corresponding display screens (12 to 14), the image information is seen from the observer.

  However, when the second and third original image information (ORG-2, ORG-3) is displayed as they are on the second and third display screens (13, 14), respectively, from the viewpoint of the observer, Since the colors appear to be mixed at the portion where the foregrounds of different image information overlap, the observer feels uncomfortable. Therefore, the CPU 18 performs correction processing on the second and third original image information (ORG-2, ORG-3) so as to eliminate such overlap, and generates corrected image information corresponding to each ( Step S2).

  More specifically, in the foreground of each original image information (ORG-2, ORG-3), the region overlapping the foreground of each original image information displayed on the near side is corrected so as to be blank. The That is, for the second original image information (ORG-2), as shown in the upper part of FIG. 6, the area overlapping the foreground of the first original image information (ORG-1) is corrected to a blank, Corrected image information (COR-2) is generated. As for the third original image information (ORG-3), the area overlapping the foreground of the first and second original image information (ORG-1, ORG-2) is blank as shown in the lower part of FIG. The third corrected image information (COR-3) is generated.

  Thereafter, the CPU 18 displays the first original image information ORG-1 on the first display screen 12, the second modified image information COR-2 on the second display screen 13, and the third modified image information COR-3 on the third display screen 14. Are given to the display control unit 17 so as to be displayed (step S3). Thereby, an image is displayed on each display screen (12-14) according to the said instruction | indication.

  As described above, in the MLD apparatus 1, with respect to the overlapping portion of the foregrounds in the original image information, the portion of all the image information except the one corresponding to the display screen on the foremost side of the original image information is blank. To be corrected. The MLD apparatus 1 displays an image on a display screen using the corrected image information.

  For this reason, with respect to the image observed by the user (the image formed together), only the foreground that is displayed on the most front side of the foreground overlaps, and the color of each overlapping foreground appears. It doesn't look mixed. As a result, the MLD apparatus 1 can be configured so that the observed image is as uncomfortable as possible to the user.

  According to the MLD apparatus 1, images are displayed on the display screens (12 to 14), and each of these images can be seen by the observer as shown in FIG. In other words, it can be said that the MLD apparatus 1 displays an image formed by combining these images toward the front side in the layer direction.

  Further, in a state where images are displayed on the display screens (12 to 14) in this way, the CPU 18 receives a selection operation for selecting a print target screen (operation for selecting a display screen to be a print target screen) by the user. Wait (step S4).

  Thus, the user can freely select any number of display screens from among all the display screens (12 to 14) through the operation of the operation button 19. When the user wants to print an image displayed on one display screen, the user selects that one display screen. In addition, when the user wants to print a composite image of each image displayed on a plurality of display screens, the user selects the plurality of display screens.

  When the user performs an operation for selecting a print target screen (Y in step S4), the CPU 18 recognizes the selected display screen or screens as the print target screen, and sets each image information corresponding to the print target screen. Are combined to generate print information (step S5). As a result, image information for one screen is generated as the print information. A more detailed description of the operation in step S5 will be described later.

  Thereafter, the CPU 18 displays the generated print information on the first display screen 12 (step S6). At this time, the second and third display screens (13, 14) are in a state where nothing is displayed (a completely blank state). As a result, the user can check the contents of the print information by looking at the first display screen 12.

  In the state where the print information is displayed, the MLD apparatus 1 accepts a user instruction as to whether or not the print information should be transmitted to the printing apparatus 2 (step S7). The user confirms the content of the print information as described above, and if printing is to be performed with this content, instructs the user to send it, and if he wants to change the print content or cancel printing, send it. It is instructed that it should not.

  When an instruction to transmit is given (Y in step S7), the MLD apparatus 1 transmits the print information to the printing apparatus 2 (step S8), and then the operation of the CPU 18 is the operation of step S3. Return to. As a result, the printing apparatus 2 receives the print information and prints the print information. As a result, the user can obtain a printed matter on which the print information is printed.

  On the other hand, when an instruction that it should not be transmitted is given (N in step S7), the print information is not transmitted to the printing apparatus 2, and the operation of the CPU 18 returns to the operation of step S3. By executing the operation of step S3 again, the display content of each display screen (12 to 14) returns to the state before the operation of step S6 is executed.

  Note that the operations in steps S6 and S7 may be omitted. In this case, after the print information is generated by the operation of step S5, the print information is immediately transmitted to the printing apparatus 2 (step S8).

[Details of operation in step S5]
Next, the operation of step S5 described above will be described in more detail with reference to the flowchart shown in FIG. More specifically, the operation in step S5 is a series of operations from step S50 to step S58 described below.

  First, the CPU 18 processes the original image information (in this embodiment, the first original image information ORG-1 corresponding to the first display screen 12) corresponding to the frontmost display screen (processing in steps S51 to S55). (Step S50). Next, the CPU 18 determines whether the original image information to be processed corresponds to the print target screen (step S51). If it is a corresponding one (Y in step S51), the CPU 18 next determines whether or not a synthesis target image (see steps S54 and S55 described later) already exists (step S52).

  As a result, when the compositing target image already exists (Y in step S52), the CPU 18 next performs the processing between the foreground of the original image information to be processed and the foreground of any compositing target image. Then, it is determined whether or not there are overlapping portions (step S53). If there is an overlapping part (Y in step S53), the CPU 18 corrects the overlapping part of the original image information to be processed to a blank, and uses the corrected image information as one of the compositing target images. (Step S54).

  On the other hand, when the compositing target image does not yet exist (N in step S52), or when the foreground of the original image information to be processed does not overlap the foreground of any compositing target image (step S53). N), the original image information to be processed is set as it is as one of the synthesis target images (without special correction) (step S55).

  After the operation of step S54 or S55 is performed, the CPU 18 determines whether all the original image information has been processed (that is, whether it has been processed) (step S56). Since the processing target is set in order from the one corresponding to the front display screen (see the operation in step S57 described later), the result of the determination related to step S56 is the original corresponding to the innermost display screen. This is the same as the result of the determination as to whether the processing has been completed for the image. Therefore, the operation in step S56 may be an operation for determining whether or not the processing has been completed for the original image corresponding to the innermost display screen.

  If there is unprocessed original image information (N in step S56), or if the original image information that is currently processed does not correspond to the print target screen (N in step S51), The CPU 18 sets the original image information corresponding to the one display screen on the back side as a processing target (step S57). That is, when the original image information corresponding to the Nth display screen from the near side is set as the current processing target, the CPU 18 selects the processing target as the original image corresponding to the N + 1th display screen from the near side. Update to information.

  On the other hand, when all the original image information has been processed (Y in step S56), the CPU 18 determines that all the synthesis target images (steps S54 or S55 performed so far) All of the image information set in the image) is combined into one image for one screen, and print information is generated (step S58).

  Here, in order to make the operation of step S5 easier to understand, how the operation is executed will be described with specific examples. In this example, the first to third original image information (ORG-1 to ORG-3) represents the image shown in FIG. In this example, it is assumed that two display screens, the first display screen 12 and the third display screen 14, are selected as print target screens.

  In this example, first, the first original image information ORG-1 corresponding to the first display screen 12 is set as a processing target (step S50). The first original image information ORG-1 corresponds to the print target screen (Y in step S51), and since no composite target image exists at this time (N in step S52), the first original image information ORG-1 corresponds to the print target screen. The image information ORG-1 is set as the synthesis target image as it is (step S55).

  Thereafter, since there is unprocessed original image information (N in Step S56), the operation in Step S57 is executed, and the second original image information ORG-2 corresponding to the second display screen 13 is set as a processing target. . However, since the second original image information ORG-2 does not correspond to the print target screen (N in Step S51), the third original image information ORG-3 corresponding to the third display screen 14 is then processed. The target is set (step S57).

  The third original image information ORG-3 corresponds to the print target screen (Y in step S51), and the composition target image (first corrected original image information ORG-1) already exists ( Y in step S52). A part of the foreground of the third original image information ORG-3 overlaps with the foreground of the synthesis target image (Y in step S53). Therefore, as shown in FIG. 8, the third original image information ORG-3 in which the overlapping portion is corrected to be blank is set as the compositing target image (step S54).

  At this stage, all the original image information has been processed (Y in step S56). Therefore, all the synthesis target images (first unmodified image information ORG-1 and modified third original image information ORG-3) are combined into one image and printed as shown in FIG. Information is generated (step S58).

  As is clear from the example described above, according to the operation in step S5, only the image corresponding to the print target screen is combined into one image, and print information is generated. Note that, according to the operation in step S5, the portion of the original image information corresponding to the print target screen that overlaps the foreground corresponds to the foremost print target screen of the original image information. This part of all original image information except for is corrected to a blank.

  As a result, for the overlapping portion of the foreground in the original image information corresponding to the print target screen, the corresponding portion of the original image information corresponding to the foremost print target screen is the print information. Is used for the synthesis for generating (step S58).

  As a result, in the image related to the print information, as for the portion where the foreground overlaps, what is displayed on the near side appears as in the case where the observer observes the MLD device 1. For this reason, the image related to the print information is configured so as not to make the user feel as uncomfortable as possible. According to the operation in step S5, when there is only one display screen selected as the print target screen, the original image information corresponding to the display screen becomes the print information as it is. As described above, even when only one display screen is selected as the print target screen, the print information is appropriately generated.

[When overlap of original image information is corrected in advance]
In addition, the image information used in the MLD apparatus 1 may be modified in order to eliminate the overlap between the foregrounds at the stage of the original image information. That is, with respect to the overlapping portion of the foregrounds in the original image information, the corresponding portions of all the original image information excluding those corresponding to the display screen on the foremost side among these original image information are previously blank. In some cases, the problem has been corrected.

  For example, the original image information (ORG-1 to ORG-3) originally having the contents shown in FIG. 5 is corrected in advance, and the original image information (ORG-1a to ORG-1a to ORG-1a) having the contents shown in FIG. In this case, image information including ORG-3a) is recorded in the built-in memory 20. In such a case, since the foregrounds of the original image information do not overlap each other, the process for eliminating the overlap between the foregrounds (the process in step S2 described above or a part of the process in step S54) is executed. It can be omitted.

  However, in this case, if the original image information corresponding to the screen to be printed has a part that has been corrected in relation to the original image information that does not correspond to the screen to be printed, the composite image information has unnecessary blanks. There is a risk of having it. As an example, the first display screen 12 is not selected as the print target screen, but the second display screen 13 is originally selected as the print target screen, and originally, the second original image information ORG shown in FIG. -2 should be the synthesis target image (there is no unnecessary blank), but in this case, the second original image information ORG-2a shown in FIG. It becomes an image.

  That is, the blank added by the correction to the second original image information ORG-2a is for eliminating the overlap with the first original image information ORG-1a, and the first original image information ORG-1a is not involved. In some cases, it can be said that the blank is unnecessary.

  Therefore, when such an unnecessary blank is generated, the MLD apparatus 1 may execute a process of filling the substitute image in the blank portion. In other words, in the original image information corresponding to the print target screen, when there is a portion that has been corrected in relation to the original image information that does not correspond to the print target screen, the substitute image is included in the corrected portion. It may be inserted.

  If it is possible to acquire information that can specify which part of the original image information has been corrected to be blank (for example, if the image information also includes the information), such processing is performed. It can be implemented. As the substitute image, for example, an image that is all or a part of the foreground arranged in other original image information and overlaps the blank portion may be employed. Further, the process of filling in the substitute image may be executed, for example, at a timing immediately before the operation of step S58 is performed.

  In this way, for example, when the first display screen 12 is not selected as the print target screen but the second display screen 13 is selected as the print target screen, as shown in FIG. An image in which a substitute image (a part of the first original image information ORG-1a that overlaps the blank portion) is inserted into an unnecessary blank of ORG-2a is a synthesis target image. Thus, unnecessary blanks are eliminated, and it is possible to make the image related to the print information as uncomfortable as possible to the user.

[Summary]
As described above, the MLD apparatus 1 according to the present embodiment causes the user to select any one or more of the plurality of display screens (12 to 14), and displays the selected display screen as the print target screen.
