Description

  The present invention relates to an image forming apparatus having a color universal function, an image display method, a program, and a recording medium.

  In recent years, as represented by terms such as accessibility, universal design, and color universal design (hereinafter also referred to as CUD), it is easy to recognize and understand signs / displays and devices / devices regardless of whether they are healthy or disabled. It has been demanded that it is easy to use.

  For example, from the viewpoint of color universal design, signs and displays of public facilities are beginning to be replaced with designs that are easy to recognize and distinguish even for elderly people, people with eye diseases, and people with color blindness.

  Similarly, in the field related to image forming systems, with regard to devices and equipment, the color scheme of buttons and operation panels, the combination of letters, the color and arrangement of LEDs, or the blinking of LEDs can also be used by elderly people, those with eye diseases, and those with color blindness. Products that have become compatible with the so-called “color universal design” that are easy to recognize and distinguish are beginning to appear.

  Therefore, if the display of the device, etc. and the operation panel are compatible with color universal design, it should be nominally easy to recognize, easy to understand, and easy to use, but in fact it is. There is no problem.

  Also, because there are several types of color blindness, just because one type is supported does not mean that it is effective for other types of color blindness, and there is no almighty color universal design. It's real.

  In addition, the device operator can specify the type of color blindness and switch to display data prepared for the specified type on the device side, or switch to display data that has been converted. Most of them are.

  For example, Patent Document 1 discloses an image forming apparatus capable of performing color component conversion processing that accurately reflects a combination of colors that can be recognized by an operator and a combination of colors that cannot be recognized.

  Further, in Patent Document 2, by using a dual-view liquid crystal display having viewing angles in different directions and giving a viewing angle from the side to the bottom, operability for a user with a low line of sight who cannot visually recognize a normal operation panel is provided. An improved display device is disclosed.

  As described above, conventionally, when using an image forming apparatus corresponding to color vision abnormality, the operator designates what color vision abnormality is, and the display data prepared corresponding to the type designated on the device side is used. Although it was possible to respond at any time, such as switching or switching the display data by conversion, there was a problem that the switching operation specified each time was troublesome.

  The method described in Patent Document 1 has a problem that it is necessary for the operator to set a color each time.

  Moreover, although the method described in Patent Document 2 takes into account individual differences in height and height, there is a problem that it does not take into account abnormal color vision.

  Therefore, the present invention has been made in view of the above problems, and a display mode is changed by both a person with color vision impairment and a healthy person by a multi-view that displays normal display data and color universal adaptation display data at the same time. An object of the present invention is to provide an image forming apparatus, an image display method, a program, and a recording medium that can confirm a menu display satisfactorily by simply changing the viewing angle.

  In order to solve the above problems, an image forming apparatus according to the present invention is an image forming apparatus provided with a multi-image display unit capable of viewing different images depending on viewing angles, and is a color universal design by converting normal display data. Display data generating means for generating color universal design adapted display data that is display data corresponding to the display data, and display image conversion for converting to normal view data and display data for multiview based on the color universal design adapted display data And the multi-image display unit displays the display data for multi-view obtained by the display image conversion unit.

  The image display method according to the present invention is an image display method of an image forming apparatus provided with a multi-image display means capable of viewing different images depending on the viewing angle, and corresponds to a color universal design by converting normal display data. Display data generating step of generating color universal design adapted display data which is the display data, and a display image converting step of converting into normal view data and display data for multiview based on the color universal design adapted display data And a multi-image display step for displaying the display data for multi-view obtained in the display image conversion step.

  A program according to the present invention causes a computer to execute the image display method described above.

  A recording medium according to the present invention is readable by a computer in which the program described above is recorded.

  According to the present invention, it is possible to provide an image forming apparatus, an image display method, a program, and a recording medium that correspond to the color universal design and do not require a display data switching operation.

The recording paper 106 transferred to the image and transferred with the image is transported by the transport means 108 to the paper discharge means 109 disposed on the left side of the apparatus main body 100A.

  A color scanner 110 serving as an image reading unit is arranged on the upper part of the apparatus main body 100A, reads a document image, and acquires image data used for plate making.

  An operation panel 111 serving as an operation unit of the stencil printing apparatus 100 is disposed on the upper front surface of the apparatus main body 100. The operation panel 111 is provided with a printing / plate making switching key 113, a start key 114, a touch panel 115 serving as a display unit, an initial setting / printer setting key 116, a printing position adjustment key 117, a printing speed setting key 118, and the like. .

  The display unit 115 is configured by an LCD touch panel, and various guidance information and various operation screens are appropriately displayed on the screen. When the operation screen is operated by an apparatus user (operator / user), The contents corresponding to the switches displayed on each screen are set in the control device 20 and the stencil printing apparatus 100.

  FIG. 2 is a diagram illustrating a configuration of the control device 20 that is installed in the apparatus main body 100 and controls each unit of the stencil printing apparatus 100.

  As shown in FIG. 2, the control device 20 is largely divided into an ACU 200 (Application Control Unit) and an ECU 300 (Engine Control Unit) serving as a mounting board.

  The ACU 200 includes an operation panel interface 205 to which an operation panel 111 of a stencil printing apparatus is connected, an interface to which an SD memory card 201 or a USB memory 203 as a portable large-capacity storage medium is connected (SD I / F 206, USB I / F 209A, 209B), an interface 208 to which a hard disk (hereinafter referred to as “HDD”) 207 serving as a mass storage device is connected, and an information terminal such as a personal computer are accessed via a network such as a LAN or the Internet.

  The stencil printing apparatus may be either a single-sided printing machine or a double-sided printing machine.

  As shown in FIG. 3, the image forming apparatus according to the present embodiment has a touch function capable of color display with respect to display / operation of the image forming apparatus, and views different images depending on viewing angles. The multi-image display means 2 (2D-3D display 115) having a function called so-called multi-view or stereoscopic view, and whether or not the display corresponding to the CUD is performed in the display of the multi-image display means. If the designation by the CUD adaptation display presence / absence designation means 3 (2D-3D display 115) and the CUD adaptation display presence / absence designation means is a setting that CUD adaptation display is to be performed, what CUD adaptation rule is used CUD adaptation rule designation means 4 (2D-3D display 115) for designating whether to perform adaptation, and normal CUD adaptation means 5 (a program operating on the ACU) for generating CUD adaptation display data designated by the CUD adaptation rule designation means from the display data, and the normal display data and the CUD adaptation display data are multiplexed. When the designation by the display image conversion means 6 (program operating on the ACU) for conversion to display data for view and the CUD adaptation display presence / absence setting means is a setting to cause CUD adaptation display, CUD adaptation The CUD adaptation display data designated by the CUD adaptation rule designation means is generated from the normal display data by the conversion means, and the normal display data and the CUD adaptation display data are converted into display data for multi-view by the display image conversion means. The normal display data and the CUD adapted display data are displayed by the multi-image display means. And control means 20 (a program operating on the ACU) that controls the display data so that any display data can be visually recognized according to the viewing angle (note: the parentheses indicate the realizing means).

  In this embodiment, the touch panel 115 of the operation panel shown in the ACU hardware configuration diagram of FIG. 2 is a stereoscopic image display device (2D-3D display) using a parallax barrier method as shown in FIG. 2D-3D means 2D-3D.

  This display converts a plurality of images to be displayed for 3D (dimensional) display, and displays them on the 2D-3D display, so that when viewed from one direction, (G1, R1, B1) ) Is seen, and when viewed from the direction 2, the image of (R2, B2, G2) is seen. By setting what takes binocular parallax into consideration, a so-called three-dimensional display that can be viewed stereoscopically is used.

  By applying this and allocating the data to be displayed so that normal display data and CUD-adapted display data can be seen depending on the viewing direction, both displays can be confirmed by changing the viewpoint, There is no need to switch the display for each color blind person.

  The stereoscopic image display apparatus can perform so-called normal (two-dimensional) display other than multi-view display or stereoscopic display, and does not perform the special display as described above, but is not the gist of the present invention. Omitted.

  Next, CUD adaptation presence / absence designation means and CUD adaptation rule designation means will be described with reference to FIGS.

  5 and 6 are examples of operation / display screens displayed on the operation / display touch panel (hereinafter simply referred to as “operation panel”, “touch panel”, etc.) of the stencil printing apparatus.

  FIG. 5 shows a screen when a virtual button of “system initial value setting”-“operation setting” item (not shown) is selected. Here, the user can make settings related to the operation of the stencil printing apparatus.

  In FIG. 5, the “CUD display” item is “ON”, which reflects a result set by an operation described later.

  When the “CUD display” virtual button is selected on the screen, a submenu shown in FIG. 6A is displayed.

  In the submenu, it is specified whether or not to display the menu based on the CUD adaptation rules listed under the virtual buttons “Yes” and “No” in the menu display of the stencil printing apparatus.

  In this embodiment, as shown in the figure, “Yes” is selected, and “P type” is specified in the CUD adaptation rule.

  P-type indicates type 1 color vision 3 color vision in color vision abnormality. Abnormal three-color vision means that red, green, and blue photoreceptors work differently from ordinary people (so-called color weakness). Type 1 indicates that red photoreceptors are not normal. ing. The two-color type color vision is a type in which either blue, green, or red photoreceptors are not working (so-called color blindness), and type 1 is that red photoreceptors are not working. Represents. By the way, the D type indicates a color vision abnormality of a 2 type 2 color vision 3 color vision, and the 2 type indicates that a green photoreceptor cell is damaged.

  Therefore, in this embodiment, a menu display with a color scheme that is easy to distinguish and recognize and a normal menu display (menu display for healthy persons) are displayed for a person with a disorder in red photoreceptor cells. Show.

  A method of detecting a portion of the menu display that does not conform to the CUD adaptation rule is performed by detecting a confusion color using a confusion color line. Depending on the type of color blindness, it is known to have coordinates called confusion color centers at different locations on the xy chromaticity diagram.

  The coordinates of the confusion color center are x = 0.747 and y = 0.253 in the P type (FIG. 6B). A group of lines drawn innumerably from the confusion color center is a confusion color line. It is known that it is difficult to discriminate between individual colors located on the same straight line of confusion color lines as different colors for color blind people. Thus, by determining whether different colors are positioned on the same mixed color line, it is possible to determine a combination of colors that are difficult to identify by a color blind person.

  In the present embodiment, the method using the confusion color line is used as a method for detecting the confusion color and a method for distributing the confusion colors so that they can be distinguished, but other methods such as a luminance difference may be used.

  Since these methods are well-known techniques and do not constitute the main requirements of the present invention, description thereof will be omitted.

  In the present embodiment, the color blindness is modeled after the expression of the Color Universal Design Organization (CUDO), but other expression formats may be used, and the present invention is not limited to this example.

  In the present embodiment, the items shown in FIG. 6A are listed as CUD conformance rules, but other items may be listed and are not limited to the present embodiment.

  Details of the control when the above settings are made will be described with reference to the flowcharts of FIGS. 7 and 8 and the schematic diagram of FIG.

  When performing the menu display of the stencil printing apparatus, the control unit of the stencil printing apparatus first acquires normal display data (step S1).

  Thereafter, the CUD adaptation display presence / absence designation is referred to (step S2), and the CUD adaptation display is determined (step S3). In the case of setting not to display CUD adaptation (step S3, NO), normal display data is displayed (step S8). In the case of setting to display (step S3, YES), CUD adaptation rule designation is further performed. Is referred to (step S4).

  In this embodiment, since “P type” is designated, the confusion color detection by the confusion color line is performed on the normal display data, and if a plurality of colors riding on the same confusion color line are used, The display data corresponding to the P type is generated by changing the color of the display data so as not to get on the same mixed color line (step S5, FIG. 19B).

  Thereafter, the normal display data and the CUD adaptation display data are converted into a format adapted for multi-view display (step S6, FIG. 19C) and displayed (step S7).

  As shown in FIG. 19C, thinning processing and pixel rearrangement are performed in order to convert to a format suitable for multi-view display.

  Originally, the image data size to be displayed was the pixel size of the image display device. However, since it is necessary to display P-type image data at the same time, thinning processing is performed in the horizontal direction.

  FIG. 8 simply shows an example in which the menu screen of the stencil printing apparatus is multi-viewed.

  For example, when a person with abnormal P-type color vision sees a normal screen display with a color scheme that does not take CUD into consideration, a portion that is difficult to see as shown in FIG.

  However, if the angle at which the menu screen is viewed is changed to take a position where the CUD compatible display corresponding to the P-type can be seen, the hard-to-view part as shown in (B) is improved, so the above problems are eliminated. The

  In addition, at this time, it is not necessary to operate a switch for display switching as in the prior art.

  The touch panel provided in the stencil printing device is small in size and not so many in number of pixels. Therefore, when displaying a single display data, it is possible to display a substantial display resolution. It will fall.

  However, it can withstand practical use if it does not take image quality degradation as a problem, such as menu display, and it will inevitably benefit if higher-definition devices become more widespread as technology advances in the future. Is not a big problem.

  In the present invention, terms such as “multi-view” and “multi-image display” are used, but this means that one screen is divided into a plurality of areas and a separate image is displayed in each area. Note that it is not used in the sense of so-called split screen display.

  The “multi-view” in the present invention means that different images can be seen by changing the viewpoint or the function of the same image display device.

  Furthermore, in this embodiment, the CUD adaptation display data is sequentially generated from the normal display data, but it is also possible to use one prepared in advance.

  In the present embodiment, the reason for the sequential generation is that while the display menu data is small, it may be generated and stored in advance, but the storage size of the data may be small, but the number of menus gradually increases. This is because the storage size is enlarged accordingly, and the preparation time is increased.

(Second Embodiment)
Next, a second embodiment will be described. Note that the same or similar parts as those in the first embodiment are denoted by the same reference numerals, and unless otherwise specified, the structural and functional descriptions already described are omitted, and only the main parts are described (others below) The same in this embodiment).

  In the embodiment, based on the block diagram of the first embodiment, as shown in FIG. 9, the image designating device 7 designates how to display the generated CUD adaptation display data. When the designation by the touch panel 115 and the CUD adaptation display presence / absence setting means is a setting that the CUD adaptation display is performed, the CUD adaptation means designates the normal display data by the CUD adaptation rule designation means. The CUD-adapted display data is generated, and the normal display data and the CUD-adapted display data are multi-viewed by the display image conversion means so that the generated display data has the appearance specified by the appearance specifying means. Normal display data and CUD-adapted display data are displayed by multi-image display means according to the viewing angle. The has a what display control means 20 for controlling so as to be seen in the data (program running on ACU), (note: in parentheses indicate the realizing means).

  Further, in this embodiment, the touch panel 115 of the operation panel shown in the ACU hardware configuration diagram of FIG. 2 is a 2D-3D display using a lenticular lens system as shown in FIG.

  This display converts a plurality of images to be displayed for 3D display, and displays them on the 2D-3D display, so that an image viewed from two directions can be seen as (B2, G2, R2), The image viewed from the direction of 1 is used such that (G1, R1, B1) can be seen, and different images can be seen depending on the viewing angle.

  Such a stereoscopic image display device is also used for so-called stereoscopic display as if an object is being viewed stereoscopically by displaying an object that is slightly changed in appearance.

  By applying this and allocating the data to be displayed so that normal display data and CUD-adapted display data can be seen depending on the viewing direction, both displays can be confirmed by changing the viewpoint, There is no need to switch the display for each color blind person.

  Next, CUD adaptation presence / absence designation means and CUD adaptation rule designation means will be described with reference to FIG.

  The CUD adaptation presence / absence designation means is the same as that of the first embodiment and is shown in FIG. 5, but when the “CUD display” virtual button is selected on the screen, the submenu shown in FIG. 11 is displayed. Is done.

  In the sub-menu, there is a supported color vision type under the virtual button for “ON” / “NO” for CUD display, and the display is specified.

  In this embodiment, as shown in the figure, “Yes” is selected, and all the supported CUD adaptation rules are designated. That is, when the appearance is set to other than “non-display”, the CUD adaptation rule and the appearance are designated.

  In the appearance, “C type” designates “center view”, “P type” designates “left view”, and “D type” designates “right view”.

  Therefore, in this embodiment, the menu display with a color scheme that is easy to distinguish and recognize for a person with a disorder in the red photoreceptor is the left view, the normal menu display is the center view, and the green photoreceptor is impaired. This shows that a menu display with a color scheme that is easy to distinguish and recognize is displayed on the right view.

  The C type is a type in which all photoreceptor cells are working. In addition, a plurality of types cannot be specified for the same view, but there may be a view with no type specification.

  The details of the control when the above settings are made are shown in the flowchart of FIG. 12, but the basic flow is the same as that of the first embodiment.

  Steps S1 to S5 are the same as in the first embodiment. The difference is that after the display data corresponding to the P type and the D type is generated from the normal display data (step S5), the appearance designation is referred to (step S10). In the first embodiment, the view is appropriately allocated by the control unit in the first embodiment. However, in this embodiment, the operator can arbitrarily designate the view, so that the normal display data and the CUD adaptation display data are specified according to this designation. Is converted into a format adapted for multi-view display (step S6) and displayed (step S7).

(Third embodiment)
Next, a third embodiment will be described. Note that the same or similar portions as those in the first and second embodiments are denoted by the same reference numerals, and the structural and functional descriptions already described are omitted unless necessary, and only the main portions are described.

  In the first and second embodiments thus far, the menu display on the operation panel of the image forming apparatus (stencil printing apparatus) has been applied to the color universal design using the multi-image display means. .

  However, the present invention can be similarly applied to color document data instead of menu display.

  In this case, for example, document data read by a color scanner included in the stencil printing apparatus, document data stored in a hard disk included in the stencil printing apparatus as a stored document, or a personal computer (PC) via a communication interface The same processing is performed on the document data transferred from, and displayed.

  However, the image size differs greatly between the document data and the menu display, and it is quite impossible to display the A3 or A4 size document data as it is on the 2D-3D display for menu display.

  If the scroll function is used, it is impossible to do so, but a complicated operation for that purpose is necessary, and the listability is lacking.

  Therefore, in this embodiment, as shown in FIG. 13, a liquid crystal display (LCD) capable of 2D-3D display is connected as an external multi-image means having a large display size suitable for document data display such as A3 / A4. The image data can be displayed without difficulty.

  As shown in the block diagram of FIG. 14, the image forming apparatus of the present embodiment can be freely detached from the image forming apparatus, can be displayed in color, and has a large display size capable of A3 / A4 display. External multi-image display means 8 (2D-3D display 500) having a function called so-called multi-view or stereoscopic view, which is for display and can see different images depending on viewing angles, and CUD adaptation When the designation by the display presence / absence setting means is a setting to display CUD adaptation, the CUD adaptation means generates CUD adaptation document data designated by the CUD adaptation rule designation means from normal document data. Then, the generated image data is usually displayed by the display image converting means so that the appearance specified by the appearance specifying means is obtained. Document data and CUD-adapted document data are converted into multi-view document data, and the normal multi-image display means displays normal document data and CUD-adapted document data. Control means 20 (a program that operates on the ACU) that controls it so that it can be visually recognized (note: the parentheses indicate implementation means).

  In the image forming apparatus having such a configuration, the setting and processing performed in the first embodiment or the second embodiment are not performed on the 2D-3D display 115 for menu display but on the 2D-3D display 500 for image display. On the other hand, since it may be performed in the same manner, detailed description is omitted.

  Note that whether the document data is displayed on the touch panel of the stencil printing apparatus or output to the external multi-image display apparatus is set in advance on a menu screen (not shown).

  FIG. 15 simply shows an example of multi-viewing original (original) color document data (A).

  In this example, for example, when a P-type color blind person sees a document data display (B) with a color scheme that does not consider CUD, there are portions that are difficult to see, such as α and β in the figure, and the image is confirmed. It may be difficult.

  However, if the angle at which the menu screen is viewed is changed to take a position where the CUD compatible display corresponding to the P-type can be seen, the hard-to-view part as shown in (C) is improved, so the above problems are eliminated. The

  In addition, at this time, it is not necessary to operate a switch for display switching as in the prior art.

(Fourth embodiment)
Next, a fourth embodiment will be described. Note that the same or similar parts as those in the first to third embodiments are denoted by the same reference numerals, and unless otherwise specified, the structural and functional descriptions already described are omitted, and only the main parts are described.

  In the present embodiment, the function is further expanded based on the third embodiment.

  That is, as shown in the ACU hardware configuration diagram of FIG. 16, the HDD 207 and the USB memory 203 are provided to store the document or image data modified / changed by the CUD adapting means.

  As shown in the block diagram of FIG. 17, the image forming apparatus is an internal storage device for storing the document or image adapted by the CUD adapting means in the image forming apparatus itself, or the image forming apparatus. By means of storage means 9 (HDD 207, USB memory 203) for storing in a portable large-capacity storage medium mounted via a slot, an explicit instruction from the operator, or a pre-specified setting, An internal storage device for storing the document or image adapted by the CUD adapting means in the image forming apparatus itself by the storage means, or a portable large capacity mounted on the image forming apparatus through a slot Control means 20 (a program that operates on the ACU) that controls to be stored in the storage medium. It is).

  Details of the control in the stencil printing machine having such a configuration will be described with reference to the flowchart of FIG.

  Since the original to be used, CUD adaptation presence / absence designation, CUD adaptation rule designation, appearance designation, and the like are the same as those in the previous embodiments, the setting and the flow of operations related to them will be described briefly.

  When a color original as shown in FIG. 15A is set in the scanner of the stencil printing apparatus and the keypress key is pressed (step S20), the original is read (step S21).

  Thereafter, the presence / absence of designation of CUD adaptation display is referred to (step S2). If the setting for displaying is made (step S3, YES), the CUD adaptation rule is further referred to (step S4).

  In this embodiment, since “P type” and “D type” are designated, display data corresponding to the P type and D type is generated from the normal display data (step S4). However, since “C type” is synonymous with normal document data in the present embodiment, although it is generated, no special mention is made regarding this data.

  After generating display data corresponding to the P type and the D type from the normal display data, the appearance designation is referred to (step S10).

  In accordance with this designation, the control unit converts the normal display data and the CUD adaptation display data into a format adapted for multi-view display (step S6) and displays it (step S7).

  Here, on the touch panel of the stencil printing apparatus, a menu (not shown) indicating what kind of treatment will be performed in the future is displayed to the operator (step S22).

  When the “document storage” virtual button is selected (step S23, YES), what kind of document data is to be stored with what document name and with what attribute (for example, access restriction is set) is illustrated. After the menu that is not to be displayed is displayed and necessary items are set, the document or image is stored as an accumulated document (step S24).

  Next, it is determined whether or not the plate making is continued (step S25). By selecting the “cancel plate making” virtual button, the subsequent processing is stopped (step S25, NO).

  Thus, the document data adapted for CUD is not only used for display but also stored as an accumulated document, and can be reused as a document in consideration of color universal design.

  That is, the stencil printing apparatus can be used as a kind of document converter.

  On the other hand, if the “continue plate making” virtual button is selected (step S25, YES), the plate making process is continued.

  Subsequent color separation processing is performed (step S26), then plate making processing (step S27) is performed, and then printing processing (step S28) is performed. Then, it is determined whether or not there is an unmade plate (step S29). If there is an unmade plate (step S29, YES), the process returns to step S27.

  In the present invention, CUD adaptation is performed on document data, and display, color separation, plate making, and printing are performed. Document data created by a document creator or the like, which can be said to be a previous stage, It can also be used as a simulator of what the color blind person sees.
