Description

[Technical field]

[0001] The present disclosure relates to an image display device, and more particularly to an image display device having a multilingual interface. [Background technology]

[0002] Recent image display devices include an image display device having a multilingual interface in which the language to be used is set based on a language selected by the user from a plurality of languages ​​corresponding to users in each country during initial setup. Once the language is set, various information will be displayed on the operation panel in that language.

[0003] In such an image display device having a multilingual interface, a language that is not intended by the user may be set due to an erroneous operation of the operation panel. However, if the incorrectly set language is one that the user does not understand, even if the user tries to change the language back, they will not be able to even open the language setting screen because the language displayed on the home screen and menu screen, including the home screen, will be written in a language that the user does not understand.

[0004] To solve such problems, a portable electronic device has been disclosed that allows the language used to be changed to a specified language by performing a specified key operation regardless of the terminal state, and allows the language setting to be easily restored to the original setting (see, for example, Patent Document 1).

[0005] Also, an electronic device has been disclosed that for the "Setup Menu" on the printer setting screen and the "Lang=" menu on the language change screen, in addition to messages in the set language, messages in the default language are displayed, allowing the user to easily change the menu language back to a language they can read even if the menu language setting is changed to a language they cannot read (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2003-234821 A [Patent Document 2] JP 2006-293585 A Summary of the Invention [Problem to be solved by the invention]

[0007] Meanwhile, multifunction copiers and other multifunction devices installed in stores such as convenience stores at airports, tourist destinations, or international event venues generally have a multilingual interface because it is expected that the multifunction devices will be used by users from various countries who speak a variety of languages.

[0008] There are currently many different types of multi-language interface-equipped multifunction devices on the market, and the functions available vary depending on the type, making it difficult for store clerks to inform users who speak different languages ​​that they must perform a specific key operation to change the language.

[0009] Furthermore, the method of displaying messages in the default language in addition to the messages in the currently selected language requires a larger display area to accommodate the dual languages, but this may not be enough to enlarge the buttons displayed on the operation panel of the multifunction device.

[0010] This disclosure has been made in consideration of the above circumstances, and provides an image display device that makes it easier than ever to restore the language even if the user accidentally changes it. [Means for solving the problem]

[0011] The image display device according to this disclosure comprises a display unit which displays various information to a user, an operation unit which accepts a change in the language of the various information, and a control unit which controls the display unit and the operation unit, and is characterized in that when the operation unit accepts a change in the language, the control unit changes the language and causes the display unit to display a predetermined display time and a key to reset the language. In addition, the image display device disclosed herein comprises a display unit that displays various information to a user, an operation unit that accepts a change in language for the various information, and a control unit that controls the display unit and the operation unit, and when the operation unit accepts a change in language, the control unit changes the language and causes the display unit to display a predetermined display time, an inquiry message asking whether the language change should be maintained, a key to maintain the language, and a key to restore the language. Effect of the Invention

[0012] According to this disclosure, by displaying a revert key for a predetermined period of time after changing the language, an image display device is realized that allows the user to revert the language more easily than before, even if they accidentally change the language.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] In this disclosure, an "image display device" is a device that displays images, and examples thereof include multifunction peripherals, personal computers (PCs), public displays, monitors such as TVs, displays such as electronic whiteboards, smartphones, and tablet terminals. The image display device disclosed herein also includes a touch panel that can be operated by touching the screen with a fingertip or the like.

[0015] Further, preferred embodiments of this disclosure will be described.

[0016] In the image display device according to the present disclosure, the undo key may be displayed in the language before the change.

[0017] In this way, by displaying a key for reverting to the language before the change, an image display device can be realized that, if a user accidentally changes the language, the user can easily revert the language even if the changed language is one that the user cannot understand.

[0018] In the image display device according to the present disclosure, the undo key may be displayed with at least one of letters, numbers, symbols, and figures.

[0019] In this way, after changing the language, a key for restoring the language is displayed in a manner understandable to users in any country, such as symbols or figures, thereby making it possible to realize an image display device that allows users from various countries who use various languages ​​to restore the language more easily than before, even if they accidentally change the language.

[0020] In the image display device according to this disclosure, when the undo key is pressed, the control unit may cause the display unit to erase the undo key and restore the language, and on the other hand, when the display time has elapsed without the undo key being pressed, the control unit may cause the display unit to erase the undo key.

[0021] In this way, an image display device can be realized that allows the user to easily restore the language to its original state by pressing a restore key after changing the language, even if the user has mistakenly changed the language.

[0022] In the image display device according to this disclosure, when the undo key is pressed, the control unit may cause the display unit to erase the undo key and restore the language, and then cause the display unit to display a language setting screen.

[0023] In this way, by displaying the language setting screen when the undo key is pressed, an image display device can be realized that allows the user to easily restore the language more easily than before, even if the user has changed the language by mistake.

[0024] In the image display device according to the present disclosure, the inquiry message, the key for maintaining the language, and the key for returning the language to the original may be displayed in the changed language.

[0025] In this way, by displaying a message in the changed language, a key to maintain the language, and a key to reset the language after the language is changed, an image display device can be realized that allows the user to reset the language more easily than before, even if the user changes the language by mistake.

[0026] The present disclosure will be described in more detail below with reference to the accompanying drawings. Note that the following description is illustrative in all respects and should not be construed as limiting the present disclosure.

[0027] [Embodiment 1] A digital multifunction peripheral 1, which is an embodiment of an image display device according to the present disclosure, will be described with reference to FIGS.

[0028] FIG. 1 is an explanatory diagram showing the appearance of a digital multifunction peripheral 1 according to a first embodiment of the present disclosure.

[0029] The digital multifunction device 1 is a device such as a multifunction device or MFP that digitally processes image data and has a copy function, a printer function, a scanner function, and a facsimile function. As shown in FIG. 1, the digital multifunction peripheral 1 includes an operation panel 16 .

[0030] FIG. 2 is a block diagram showing a schematic configuration of the digital multifunction peripheral 1 of FIG.

[0031] As shown in FIG. 2, the digital multifunction peripheral 1 includes a control unit 10, an image data acquisition unit 11, an image forming unit 12, a storage unit 13, an image processing unit 14, a communication unit 15 and an operation panel 16.

[0032] Each component of the digital multifunction peripheral 1 will be described below.

[0033] The control unit 10 controls the digital multifunction peripheral 1 in an integrated manner, and includes a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), various interface circuits, and the like.

[0034] In order to control the overall operation of the digital multifunction peripheral 1, the control unit 10 monitors and controls all loads such as the detection of each sensor, motors, clutches, and the operation panel 16.

[0035] The image data acquisition unit 11 is a part that reads a document placed on a document reading table and acquires image data. Furthermore, the image data acquisition unit 11 may acquire image data in a USB via a USB connector or the like (not shown). Furthermore, image data may be acquired from an external terminal or the like via a wired or wireless network (not shown).

[0036] The image forming unit 12 is a part that prints out the image data acquired by the image data acquiring unit 11 and processed by the image processing unit 14 onto a sheet of paper.

[0037] The storage unit 13 is an element or storage medium that stores information and control programs necessary to realize various functions of the digital multifunction device 1. For example, a semiconductor element such as a RAM or a ROM, a hard disk, a flash storage unit, an SSD (Solid State Drive), or other storage medium is used.

[0038] The storage unit 13 stores data necessary for executing a job, such as information about a job such as printing, and image data. Furthermore, the storage unit 13 stores a plurality of types of language information and language setting data.

[0039] The program and data may be stored in different devices, such as by configuring the area for storing data in a hard disk drive and the area for storing programs in a flash memory unit.

[0040] The image processing unit 14 converts the image data input from the image data acquisition unit 11 into an appropriate electrical signal based on the analysis results of job commands such as printing acquired through the operation unit 162, and processes the signal so that it is suitable for output such as enlargement / reduction.

[0041] The communication unit 15 is a part that communicates with external terminals (not shown) via a network and transmits and receives various data.

[0042] The operation panel 16 is composed of a display panel made up of a liquid crystal panel or the like, and a touch panel such as a capacitive touch panel arranged on top of the display panel to detect the position touched by a finger, and is equipped with a display unit 161 and an operation unit 162.

[0043] The display unit 161 is a part that displays various types of information. Display unit 161 is, for example, a CRT display, a liquid crystal display, an EL display, or the like, and is a display device such as a monitor or line display for displaying electronic data such as the processing state of the operating system and application software.

[0044] The control unit 10 displays the operation and status of the digital multifunction peripheral 1 through the display unit 161 .

[0045] The operation unit 162 is an interface for operating the digital multifunction peripheral 1, and is a section that receives commands from the user.

[0046] <An example of language settings of the digital multifunction device 1 according to the first embodiment of the present disclosure> Next, an example of language setting of the digital multifunction peripheral 1 according to the first embodiment of the present disclosure will be described with reference to FIGS.

[0047] FIG. 3 is an explanatory diagram showing an example of a home screen displayed in Japanese on the display unit 161 of the digital multifunction peripheral 1 of FIG.

[0048] Here, if the user wishes to change the home screen displayed in Japanese to English, the user changes the language setting on the language setting screen.

[0049] FIG. 4 is an explanatory diagram showing an example of a language setting screen displayed on the display unit 161 of the digital multifunction peripheral 1 of FIG.

[0050] Users can change the language by clicking "Settings" at the bottom of the home screen, then "System Settings," "Common Settings," "Operation Settings," and "Basic Settings" in that order, and then in the "Language Settings" section, selecting the desired language from the list of multiple languages ​​shown in Figure 4 and pressing the "Update" key.

[0051] In the example of FIG. 4, "American English" is selected from among "Japanese", "American English", "English", "Spanish", "French" and "German", etc. If you press the "Update" key in this state, the display will switch to the home screen and the language will change from Japanese as shown in Figure 3 to English as shown in Figure 5.

[0052] By automatically switching to the home screen after changing the language in this way, it is possible to realize a highly convenient digital multifunction printer 1 since it eliminates the need for users to perform operations after switching languages, particularly in digital multifunction printers 1 installed in convenience stores in tourist areas where there is a high possibility that languages ​​will be changed frequently.

[0053] FIG. 5 is an explanatory diagram showing an example of a home screen displayed in English on the display unit 161 of the digital multifunction peripheral 1 of FIG.

[0054] As shown in FIG. 4, when "American English" is selected in the language settings, the home screen will also be written in English, as shown in FIG.

[0055] However, in the case of the digital multifunction device 1, which is likely to be used by users from various countries, the language setting may be changed multiple times, and the user may mistakenly change the setting language to a language that the user does not understand. In such a case, if the user does not understand the language, it will be difficult for them to go to the "Language Settings" screen from the home screen and change the set language back to the original language.

[0056] Therefore, in the digital multifunction peripheral 1 according to the first embodiment of the present disclosure, the following process is carried out after changing the language to solve this problem.

[0057] <Display process after changing language of digital multifunction peripheral 1 according to embodiment 1 of the present disclosure>

[0058] Next, a display process after changing the language of the digital multifunction peripheral 1 according to the first embodiment of the present disclosure will be described with reference to FIGS.

[0059] FIG. 6 is a flowchart showing an example of processing after the language is changed in the digital multifunction peripheral 1 of FIG.

[0060] In step S1 of FIG. 6, the control unit 10 of the digital multifunction peripheral 1 determines whether or not the language has been changed (step S1).

[0061] If the language has been changed (if the determination in step S1 is Yes), in step S2, the control unit 10 causes the display unit 161 to display a key for returning the language to the original state (step S2).

[0062] FIG. 7 shows an example of a display of a key for returning the language to the original language after changing the language from Japanese to English in the digital multifunction peripheral 1 of FIG.

[0063] As shown in FIG. 7, a language "return" key is displayed on display unit 161 for a predetermined period of time. When the user presses this key, the language will be changed back to the previous setting.

[0064] FIG. 8 shows an example of a display of a key for returning the language to the original language after changing the language from English to Japanese in the digital multifunction peripheral 1 of FIG.

[0065] As shown in FIG. 8, when the language is changed from English to Japanese, the "undo" key is displayed as "UNDO" in English, which is the language before the change.

[0066] In this way, by displaying an "Undo" key in the language before the change, the user can easily revert the language even if they accidentally change the language or if the changed language is one that the user does not understand.

[0067] Next, in step S3 of FIG. 6, the control unit 10 determines whether or not the "undo" key has been pressed (step S3).

[0068] If the "Undo" key is pressed (if the determination in step S3 is Yes), in step S4, the control unit 10 erases the "Undo" key on the display unit 161 and restores the language setting (step S4), and then terminates the processing.

[0069] On the other hand, if the “Undo” key has not been pressed (if the determination in step S3 is No), in step S5, the control unit 10 determines whether or not a predetermined time has elapsed after the language was changed (step S5).

[0070] In the example of FIG. 4, the "Message display time setting" is set to "10 seconds," but the user can set this display time as desired.

[0071] If a predetermined time has elapsed after the language change (if the determination in step S5 is Yes), in step S6, control unit 10 causes display unit 161 to erase the “Undo” key (step S6), and then ends the process. That is, in this case, the language is not reverted back to the original language, and the changed language remains reflected.

[0072] On the other hand, if the predetermined time has not elapsed since the language was changed (if the determination in step S5 is No), the control unit 10 returns the process to step S2.

[0073] In this way, by displaying an "Undo" key in the language before the change for a predetermined period of time after the language is changed, it is possible to realize a digital multifunction machine 1 that allows the user to easily restore the language compared to the conventional case, even if the user changes the language by mistake.

[0074] (Variation 1) As a first variant, instead of displaying an "Undo" key or an "UNDO" key, a key labeled "Japanese" key (when changing from Japanese to English) or "English" key (when changing from English to Japanese) may be displayed.

[0075] In addition to the "Undo" key, a message such as "Language has been changed" may also be displayed.

[0076] (Variation 2) As a second modification, the "undo" key may be displayed as a symbol or a graphic.

[0077] FIG. 9 shows another example of a display of a key for returning the language to the original language after changing the language from Japanese to English in the digital multifunction peripheral 1 of FIG.

[0078] As shown in FIG. 9, if the language is changed, a rotating arrow symbol is displayed as the "undo" key.

[0079] Note that the symbol is not limited to the rotating arrow symbol, and may include other symbols, letters, numbers, and figures, as long as it can be intuitively understood by users in different countries who speak different languages. For example, it may be a mark of the flag of each country, letters of each country such as "A" (English) and "a" (Japanese), illustrations of people speaking a language, or an icon such as a keyboard. It may also be any combination of letters, numbers, symbols and figures.

[0080] In this way, after changing the language, an "Undo" key can be displayed in symbols, figures, or other formats that can be understood by users in each country. This makes it possible to realize a digital multifunction device 1 that allows the user to easily restore the language more easily than before, even if the user accidentally changes the language.

[0081] [Embodiment 2] <Display process after changing language of digital multifunction peripheral 1 according to embodiment 2 of the present disclosure> Next, a display process after changing the language of the digital multifunction peripheral 1 according to the second embodiment of the present disclosure will be described with reference to FIGS.

[0082] The first embodiment is characterized in that, after the language is changed, an "Undo" key is displayed in the language before the change.

[0083] On the other hand, the second embodiment is characterized in that, after the language is changed, a message is displayed inquiring the user as to whether or not to maintain the change of language in the changed language.

[0084] The schematic configuration of the digital multifunction peripheral 1 according to the second embodiment of the present disclosure is similar to that of the first embodiment (FIGS. 1 and 2), and therefore a description thereof will be omitted.

[0085] FIG. 10 is a flowchart showing an example of processing after changing the language of the digital multifunction peripheral 1 according to the second embodiment of the present disclosure.

[0086] In step S11 of FIG. 10, the control unit 10 determines whether or not the language has been changed (step S11).

[0087] If the language has been changed (if the determination in step S11 is Yes), in step S12, the control unit 10 causes the display unit 161 to display a message inquiring whether or not to maintain the change in language (step S12).

[0088] FIG. 11 shows an example of a message displayed to inquire whether or not to maintain the language change after the language change from Japanese to English in the digital multifunction peripheral 1 of FIG.

[0089] In the example of FIG. 11, the display unit 161 displays a message asking whether to maintain the language settings, along with an English message indicating that the language settings will return to the original settings after 10 seconds: "Keep language settings? 10 seconds to return to original language setting." Along with the message, "Keep changes" and "UNDO" keys are also displayed. Unlike the first embodiment, these messages and keys are displayed in the changed language.

[0090] In this way, by displaying messages and keys in the changed language, even if the user accidentally changes the language, if the messages and keys are displayed in a language that the user does not understand, the user will leave these keys unpressed, and the original language will automatically be restored after a specified time.

[0091] Next, in step S13 of FIG. 10, the control unit 10 determines whether or not the "undo" key has been pressed (step S13).

[0092] If the "Restore" key is pressed (if the determination in step S13 is Yes), in step S14, control unit 10 causes display unit 161 to erase the message and restores the language setting (step S14), and then ends the process.

[0093] On the other hand, if the "Undo" key has not been pressed (if the determination in step S13 is No), in step S15, the control unit 10 determines whether the language "Keep Change" key has been pressed or whether a predetermined time has elapsed since the language was changed (step S15).

[0094] If the language "keep change" key is pressed or a predetermined time has elapsed since the language was changed (if the determination in step S15 is Yes), in step S16, the control unit 10 causes the display unit 161 to erase the message (step S16) and then terminates the processing.

[0095] On the other hand, if the language "keep change" key is not pressed and the predetermined time has not elapsed since the language was changed (if the determination in step S15 is No), the control unit 10 returns the process to step S12.

[0096] In this way, by displaying messages and keys in the changed language for a predetermined period of time after the language is changed, it is possible to realize a digital multifunction machine 1 that allows the user to easily return the language to the original language more easily than before, even if the user changes the language by mistake.

[0097] [Embodiment 3] <Display process after changing language of digital multifunction peripheral 1 according to embodiment 3 of the present disclosure> Next, a display process after changing the language of the digital multifunction peripheral 1 according to the third embodiment of the present disclosure will be described with reference to FIG.

[0098] The first embodiment is characterized in that after the language is changed, an "Undo" key is displayed in the language before the change, and when the "Undo" key is pressed, the language is restored to the original language.

[0099] On the other hand, the third embodiment is characterized in that after the language is changed, an "Undo" key is displayed in the language before the change, and when the "Undo" key is pressed, the language setting screen is displayed.

[0100] FIG. 12 is a flowchart showing an example of processing after changing the language of the digital multifunction peripheral 1 according to the third embodiment of the present disclosure.

[0101] In step S31 of FIG. 12, the control unit 10 of the digital multifunction peripheral 1 determines whether or not the language has been changed (step S31).

[0102] If the language has been changed (if the determination in step S31 is Yes), in step S32, the control unit 10 causes the display unit 161 to display a key for returning the language to the original state (step S32).

[0103] Next, in step S33, the control unit 10 determines whether or not the "restore" key has been pressed (step S33).

[0104] If the "Undo" key is pressed (if the determination in step S33 is Yes), in step S34, the control unit 10 erases the "Undo" key on the display unit 161 and displays the language setting screen (step S34), and then terminates the processing.

[0105] By displaying the language setting screen in this manner, even if the user accidentally changes the language, the language setting screen is still displayed, making it possible to easily change to the desired language.

[0106] On the other hand, if the “Undo” key has not been pressed (if the determination in step S33 is No), in step S35, the control unit 10 determines whether or not a predetermined time has elapsed after the language was changed (step S35).

[0107] If a predetermined time has elapsed after the language change (if the determination in step S35 is Yes), in step S36, control unit 10 causes display unit 161 to erase the "Undo" key (step S36), and then ends the process.

[0108] On the other hand, if the predetermined time has not elapsed since the language was changed (if the determination in step S35 is No), the control unit 10 returns the process to step S32.

[0109] In this way, after the language is changed, an "Undo" key is displayed for a predetermined period of time in the language before the change, and the language setting screen is displayed when the key is pressed, thereby realizing a digital multifunction device 1 that allows the user to easily restore the language more easily than before, even if the user accidentally changes the language.

[0110] (Modification) As a modified example, even when deleting the message and returning the language to the original as shown in the second embodiment (step S14 in FIG. 10), the language setting screen may be displayed.

[0111] [Embodiment 4] <Display process when changing language of digital multifunction peripheral 1 according to embodiment 4 of this disclosure> Next, a display process when changing the language of the digital multifunction peripheral 1 according to the fourth embodiment of the present disclosure will be described with reference to FIGS.

[0112] The second embodiment is characterized in that, after the language is changed, a message is displayed inquiring the user as to whether or not to maintain the changed language.

[0113] On the other hand, the fourth embodiment is characterized in that when the language is changed, the language is not changed immediately, but a message is displayed to inquire the user whether or not to change to the new language.

[0114] The schematic configuration of the digital multifunction peripheral 1 according to the fourth embodiment of this disclosure is similar to that of the first embodiment (FIGS. 1 and 2), and therefore a description thereof will be omitted.

[0115] FIG. 13 is a flowchart showing an example of a process performed when changing the language of the digital multifunction peripheral 1 according to the fourth embodiment of the present disclosure.

[0116] In step S41 of FIG. 13, the control unit 10 determines whether or not a change in language has been accepted (step S41).

[0117] When a request to change the language has been accepted (if the determination in step S41 is Yes), in step S42, the control unit 10 causes the display unit 161 to display a message inquiring whether or not to change the language (step S42).

[0118] FIG. 14 is an example of a message display inquiring whether or not to change the language when changing the language from Japanese to English in the digital multifunction peripheral 1 according to the fourth embodiment of this disclosure.

[0119] In the example of FIG. 14, the display unit 161 displays an inquiry as to whether to change the language, along with an English message "Change language settings? The message "language is changed to English until 10 seconds" is displayed. Along with the above message, an "OK" key and a "CANCEL" key are also displayed. Unlike the second embodiment, the language has not been changed at the time the above message is displayed.

[0120] In this way, by displaying the message and key in the new language, the user can know in advance from the message what language will actually be changed to. Therefore, even if the user accidentally sets the language to be changed, the language will not be changed to the wrong language by leaving the key unpressed.

[0121] For example, if an American accidentally selects "Spanish" when changing the language on the language settings screen, Spanish messages and keys will be displayed, making it easy for them to realize that they have selected the wrong language.

[0122] Next, in step S43 of FIG. 13, the control unit 10 determines whether or not the "cancel" key has been pressed (step S43).

[0123] If the "Cancel" key is pressed (if the determination in step S43 is Yes), in step S44, the control unit 10 causes the display unit 161 to erase the message (step S44), and then ends the process. In this case the language is not changed.

[0124] On the other hand, if the "Cancel" key has not been pressed (if the determination in step S43 is No), in step S45, the control unit 10 determines whether the "OK" key has been pressed or whether a predetermined time has elapsed since the language change was accepted (step S45).

[0125] If the "OK" key is pressed or a predetermined time has elapsed after the language change has been accepted (if the determination in step S45 is Yes), in step S46, control unit 10 causes display unit 161 to erase the message, changes the language (step S46), and then terminates the process.

[0126] On the other hand, if the "OK" key is not pressed and the predetermined time has not elapsed since the language change was accepted (if the determination in step S45 is No), the control unit 10 returns the process to step S42.

[0127] In this way, by displaying messages and keys in the changed language for a specified period of time when the language is changed, it is possible to realize a digital multifunction machine 1 that will not change to an incorrect language even if the user mistakenly sets the language to be changed.

[0128] (Modification) As a modified example, when the "cancel" key is pressed, the language setting screen may be displayed.

[0129] In this way, if the user realizes that he or she has made a mistake in the language setting and presses the "Cancel" key, the user can change the language back to the desired language.

[0130] Preferred aspects of the present disclosure include any combination of the above-mentioned aspects.

[0131] In addition to the above-mentioned embodiment, various modifications of this disclosure are possible. These modifications should not be interpreted as not belonging to the scope of this disclosure. This disclosure should include all modifications within the scope of the claims and the equivalent meanings. [Explanation of symbols]
