[0011]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described in detail below with reference to the drawings.
[0012]
(1) Configuration of mobile phone
In FIG. 1, reference numeral 1 denotes a mobile phone as a whole, and an upper housing 2 and a lower housing 3 are configured to be foldable via a hinge portion 4.
[0013]
In the upper housing 2, a transmission / reception antenna 5 is attached in a state where it can be pulled out and housed on the upper right side of the back surface thereof, and a speaker 6 is provided at the front upper end portion. Is provided with a display unit 7 formed of a liquid crystal display or the like.
[0014]
In the lower housing 3, a numeric keypad 8 including "0" to "9", "#" and "*" keys is provided at the center of the surface, and the user's voice is provided at the lower end of the surface. A microphone 9 for collecting sound etc. is provided.
[0015]
Further, the lower housing 3 is provided with a jog dial 10 that can be rotated and pressed in the vertical direction at the upper end portion of the surface thereof, and the left direction is designated on both sides of the jog dial 10. A left direction key 11 for specifying the right direction and a right direction key 12 for specifying the right direction are provided.
[0016]
Next, the circuit configuration of the mobile phone 1 will be described with reference to FIG. The cellular phone 1 has a central processing unit (CPU) 20 that controls the cellular phone 1 as a whole, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, and an antenna 5 via a control line 21. A communication processing unit 24, an e-mail processing unit 25, a control unit 26 including a numeric keypad 8, a jog dial 10, a left direction key 11, a right direction key 12, and the like and a display unit 7 are connected. Has been. The CPU 20, ROM 22, RAM 23, communication processing unit 24, e-mail processing unit 25, display unit 7, speaker 6, and microphone 9 are connected to each other via a data line 27.
[0017]
Various programs such as a basic program are stored in the ROM 22 in advance. The CPU 20 reads out various programs stored in the ROM 22 as appropriate, expands them in the RAM 23 and executes them, thereby controlling each circuit unit of the mobile phone 1 and executing various processes.
[0018]
Further, the email processing unit 25 responds to a command from the CPU 20 to send and receive emails for sending and receiving emails, and to create emails for creating emails to be sent to other users (described later). A received mail display process (to be described later) for displaying the contents of an electronic mail received from another user (hereinafter also referred to as a received mail) on the display unit 7 is executed.
[0019]
(2) Email creation process
For example, when a predetermined operation for starting creation of an e-mail is performed by the user via the operation unit 26, the CPU 20 controls the e-mail processing unit 25 to execute an e-mail creation process. That is, the CPU 20 enters from the start step of the e-mail creation processing procedure RT1 shown in FIG. 3, for example, and proceeds to step SP1.
[0020]
In step SP1, for example, after the user inputs a destination e-mail address, e-mail subject, and the like via the operation unit 26, the CPU 20 performs a predetermined operation for starting input of the body of the e-mail. Then, for example, a secret mode selection screen 50A as shown in FIG. 4A is displayed on the display unit 7, and the process proceeds to step SP2.
[0021]
In step SP2, the CPU 20 determines whether or not the selection item “YES” is selected and determined by the selection cursor 51 when the selection cursor 51 in the secret mode selection screen 50A is operated by the user via the operation unit 26. To do.
[0022]
If a negative result is obtained in this step SP2, for example, this means that the selection item “NO” in the secret mode selection screen 50A has been selected and determined by the user, that is, the body of the electronic mail is created in a highly confidential state. This means that the user has no intention. At this time, the CPU 20 moves to step SP3 and executes the text creation process in the normal mode, thereby inputting the text of the e-mail with low confidentiality to the user. Let
[0023]
On the other hand, if an affirmative result is obtained in step SP2, for example, this means that the user is willing to create the text of the e-mail in a highly confidential state. Move to SRT1 and execute the text creation process in the secret mode.
[0024]
That is, for example, the CPU 20 enters from the start step of the text creation processing procedure SRT1 in the secret mode shown in FIG. 5, and proceeds to step SP11.
[0025]
In step SP11, for example, as shown in FIG. 4B, the CPU 20 displays a text creation screen 60 for causing the user to create the text of the e-mail on the display unit 7, and proceeds to step SP12.
[0026]
Here, the background color of the text creation screen 60 is white. In the text creation screen 60, a character clear display window WND is displayed. When the CPU 20 recognizes that a character exists in the frame of the character clear display window WND, the character existing in the frame is displayed. Is clearly displayed in black that stands out from the background color.
[0027]
On the other hand, the CPU 20 recognizes the outside of the frame of the character clear display window WND as a region AR (hereinafter referred to as a concealed region) AR to be displayed with the characters concealed.
[0028]
In the figure, for convenience of explanation, the concealment area AR is clearly shown by surrounding it with a broken line, but this broken line does not actually exist.
[0029]
In step SP12, the CPU 20 starts executing a window size changing process for changing the size of the character clear display window WND. For example, when the right key 12 or the left key 11 is pressed by the user at this time, FIG. As shown in FIG. 4C, when the width of the character clear display window WND is enlarged or reduced according to this and the jog dial 10 is rotated downward or upward by the user, the character clear is accordingly displayed. The vertical width of the display window WND is enlarged or reduced. When a predetermined operation is performed by the user via the operation unit 26, the window size changing process is terminated, and the process proceeds to step SP13.
[0030]
In step SP13, for example, when the user inputs a plurality of characters “Yukiga” in hiragana via the operation unit 26, for example, as shown in FIG. A plurality of the inputted characters “Yukiga” are displayed in the frame of the character clarity display window WND together with the underline UL for showing, thereby displaying the plurality of characters “Yukiga” clearly in black. The process proceeds to step SP14.
[0031]
As described above, the CPU 20 designates the character before being converted to Kanji (in this case, “Yukiga”) by the character clear display window WND, whereby the character before the Kanji conversion is displayed on the display unit 7. Are clearly displayed in black.
[0032]
In step SP14, for example, when the user performs a kanji conversion operation for converting kanji through the operation unit 26, for example, as shown in FIG. 6B, the CPU 20 displays a plurality of characters “Yukiga” in hiragana. For example, “Yukiga” is displayed in the character clear display window WND as the first kanji conversion candidate, and the process proceeds to step SP15.
[0033]
As described above, the CPU 20 designates the character under Kanji conversion (in this case, “Yukiga”) by the character clear display window WND, whereby the character under Kanji conversion is displayed on the display unit 7. And is clearly displayed in black.
[0034]
In step SP15, for example, as shown in FIG. 6C, as a result of the above-described kanji conversion operation being performed again by the user via the operation unit 26, the CPU 20 determines the second character “Yukiga”. When a kanji conversion confirming operation for confirming the kanji conversion is performed via the operation unit 26 in a state where “Yukiga” is displayed in the frame of the character clear display window WND as the kanji conversion candidate of FIG. As shown in (A), the underline UL that has been displayed so far is canceled and the character clear display window WND is moved to the rear of the plurality of characters “Yukiga” whose kanji conversion has been confirmed. The character “Yukiga” is positioned outside the frame of the character clear display window WND (that is, the concealment area AR), and the process proceeds to step SP16.
[0035]
At this time, the CPU 20 approximates the character color of the plurality of characters “Yukiga” after the kanji conversion confirmed to exist in the concealment area AR to the background color (that is, white) of the text creation screen 60 (for example, white). By changing to light gray), the characters “Yukiga” after confirmation of the conversion to kanji are not easily visible, that is, the characters “Yukiga” after confirmation of conversion to kanji are hidden and displayed. It is made to do.
[0036]
In step SP16, the CPU 20 determines whether or not an end operation for ending the creation of the body of the e-mail has been performed. If a negative result is obtained here, for example, this is performed by the user via the operation unit 26. This means that characters are continuously input. At this time, the process proceeds to step SP13.
[0037]
In step SP13 for the second time, for example, when a user inputs a plurality of characters “handed” in hiragana via the operation unit 26, the CPU 20 aligns with the underline UL as shown in FIG. 7B, for example. The plurality of inputted characters “Futaku” are displayed in the frame of the character clear display window WND, thereby displaying the plurality of characters “Futatsu” clearly in black, and the process proceeds to Step SP14. .
[0038]
In step SP14 for the second time, for example, when the user performs a kanji conversion operation for converting kanji through the operation unit 26, as shown in FIG. For example, “was waving” is displayed in the character clear display window WND as the first kanji conversion candidate of “it was”, and the process proceeds to step SP15.
[0039]
At this time, a plurality of characters “waving” that are being converted into Kanji are displayed clearly in black on the display unit 7.
[0040]
In step SP15 for the second time, for example, as a result of the above-described kanji conversion operation being performed again by the user via the operation unit 26, the CPU 20 indicates that a plurality of characters “was touched” as shown in FIG. When a kanji conversion confirmation operation for confirming the kanji conversion is performed via the operation unit 26 in a state where “falling” is displayed as the second kanji conversion candidate within the frame of the character clear display window WND. For example, as shown in FIG. 8 (B), the underlined UL displayed so far is stopped, and the character clear display window WND is moved to the back of a plurality of characters “falling” whose kanji conversion has been confirmed. As a result, the plurality of characters “falling” are positioned in the hidden area AR, and the process proceeds to step SP16.
[0041]
At this time, the CPU 20 displays a plurality of characters “falling” after the kanji conversion is confirmed by the character color approximate to the background color of the text creation screen 60 on the display unit 7, so that the kanji conversion after the kanji conversion is confirmed. It is designed to conceal multiple characters “falling”.
[0042]
In step SP16 for the second time, the CPU 20 determines whether or not an end operation for ending the creation of the body of the email has been performed. If an affirmative result is obtained, for example, this indicates that this is the body of the email. This means that the creation work has been completed. At this time, the process moves to step SP4 of the email creation processing procedure RT1 (FIG. 3) to finish the email creation processing procedure.
[0043]
In this way, as shown in FIGS. 7A to 7C, for example, the CPU 20 removes a plurality of characters “Yukiga” that have already been confirmed for kanji conversion from the designation of the character clear display window WND, and before the kanji conversion. The character clear display window WND designates a plurality of characters “Waiting” and a plurality of characters “waving” during Kanji conversion. As a result, a plurality of characters “Yukiga” for which kanji conversion has already been confirmed are concealed and displayed on the display unit 7. On the other hand, a plurality of characters “Futatsu” before kanji conversion and a plurality of characters being converted to kanji are displayed. The character “was waving” is clearly displayed on the display unit 7.
[0044]
Accordingly, for example, even if a text creation screen 60 having a state as shown in FIGS. 7A to 7C is viewed by another person other than the user who creates the text of the e-mail, The meaning of the text (that is, “snow was falling”) can be reliably prevented from being easily guessed or grasped.
[0045]
(3) Received mail display processing
On the other hand, for example, when the user performs a text display operation for displaying the text of the received mail on the display unit 7 through the operation unit 26, the CPU 20 controls the email processing unit 25 to perform the received mail display process. It is made to run. That is, the CPU 20 enters, for example, from the start step of the received mail display processing procedure RT2 shown in FIG. 9, and proceeds to step SP21.
[0046]
In step SP21, for example, when the above-described text display operation is performed by the user via the operation unit 26, the CPU 20 displays a secret mode selection screen 50B as shown in FIG. 10A, for example, and proceeds to step SP22. Move.
[0047]
In step SP22, the CPU 20 determines whether or not the selection item “YES” is selected and determined by the selection cursor 51 when the selection cursor 51 in the secret mode selection screen 50B is operated by the user via the operation unit 26. To do.
[0048]
If a negative result is obtained in step SP22, for example, this means that the user has selected the selection item “NO” in the secret mode selection screen 50B, that is, the intention to display the text of the received mail in a highly confidential state. The CPU 20 moves to step SP23 and executes the text display process in the normal mode, thereby displaying the text of the e-mail to the display unit 7 in a state of low secrecy. indicate.
[0049]
On the other hand, if a positive result is obtained in step SP22, for example, this means that the user has an intention to display the text of the received mail in a highly confidential state. At this time, the CPU 20 executes a subroutine. Move to SRT2 and execute the text display process in the secret mode.
[0050]
That is, the CPU 20 enters from the start step of the text display processing procedure SRT2 in the secret mode shown in FIG. 11, and proceeds to step SP31.
[0051]
In step SP31, for example, as shown in FIG. 10B, the CPU 20 displays a text display screen 70 for displaying the text of the received mail on the display unit 7, and proceeds to step SP32.
[0052]
Here, the background color of the text display screen 70 is white. In the text display screen 70, a text clarity display window WND is displayed, and the CPU 20 has a background color of a plurality of characters “Good morning! Now” in the text present in the frame of the text clarity display window WND. It is designed to display clearly in black that stands out from the screen.
[0053]
On the other hand, the CPU 20 recognizes the outside of the frame of the character clear display window WND as a hidden area AR that should be displayed while concealing characters, and all the characters in the text existing in the hidden area AR are displayed. A character color similar to the background color (for example, light gray) is displayed.
[0054]
In step SP32, the CPU 20 starts executing the window size changing process described above. For example, as shown in FIG. 10C, the CPU 20 starts the character clear display window WND in accordance with the operation of the right arrow key 12 by the user. After enlarging the width, the process proceeds to step SP33.
[0055]
In step SP33, for example, when the jog dial 10 is rotated downward by a predetermined amount by the user, the CPU 20 sets the character clear display window WND in the text display screen 70 to 1 as shown in FIG. 12, for example. By moving down the line, a plurality of characters “weather” are newly designated by the character clear display window WND, and a plurality of newly designated characters “weather” are added accordingly. Is clearly displayed in black, and a plurality of characters “Good morning! Today is good” that are not specified in the character clarity display window WND are changed to a character color approximate to the background color of the text display screen 70, and the process proceeds to step SP34. .
[0056]
In step SP34, the CPU 20 determines whether or not an end operation for ending the display of the text of the received mail has been performed. If a negative result is obtained here, for example, this is continued by the user. Is read, and the process proceeds to step SP33 described above.
[0057]
In step SP33 for the second time, for example, when the jog dial 10 is rotated upward by a predetermined amount by the user, as shown in FIG. 10C, the CPU 20 clears the text in the text display screen 70 accordingly. By moving the display window WND up by one line, the character clear display window WND makes a plurality of characters “Good morning! “Good morning! Today is good” is clearly displayed in black, and a plurality of characters “weather” which are not specified in the character clear display window WND are changed to a character color approximate to the background color of the text display screen 70. The process proceeds to step SP34.
[0058]
In this manner, the CPU 20 clearly displays a plurality of characters (for example, “Good morning! Good today”) designated by the character clarity display window WND on the display unit 7 in black. All characters in the text that are not designated by the display window WND are hidden and displayed.
[0059]
In step SP34 for the second time, the CPU 20 determines whether or not an end operation for ending the display of the text of the received mail has been performed. If an affirmative result is obtained here, for example, this means that the text of the received mail is displayed. Is ended, and at this time, the process proceeds to step SP24 of the received mail display processing procedure RT2 (FIG. 9), and the received mail display process is ended.
[0060]
(4) Operation and effect
In the above configuration, when the mobile phone 1 displays the body of the e-mail being created by the user, the mobile phone 1 includes a character (for example, “ “Was touching” or “waving” (FIG. 7)) is clearly displayed on the display unit 7.
[0061]
Thereby, the user who is creating the text of the e-mail can surely confirm the characters input via the operation unit 26 by viewing the display unit 7.
[0062]
On the other hand, at this time, the mobile phone 1 displays all characters (for example, “Yukiga” (FIG. 7)) that have already been confirmed for kanji conversion, that is, all characters in the text before and during kanji conversion. 7 is hidden and displayed.
[0063]
As a result, even if the display unit 7 is peeped by someone other than the user who creates the body of the email, all the characters in the body of the email are not clearly displayed. It can be remarkably prevented that the whole sentence meaning (in this case, “snow was falling”) is easily guessed or grasped.
[0064]
Further, when the mobile phone 1 displays the text of the received mail on the display unit 7, for example, as shown in FIG. 12, among the plurality of characters constituting the text, the mobile phone 1 is designated by the character clear display window WND. Characters (for example, “weather” in this case) are clearly displayed on the display unit 7.
[0065]
As a result, the user of the mobile phone 1 reading the text of the received mail appropriately moves the text clear display window WND in the text display screen 70 via the jog dial 10, whereby the contents of the entire text of the received mail are displayed. Can be grasped.
[0066]
On the other hand, at this time, the cellular phone 1 hides and displays all the characters in the text not designated by the character clear display window WND from the display unit 7.
[0067]
As a result, even if the display unit 7 is peeped by someone other than the user who is reading the text of the received mail, all the characters in the text of the received mail are not clearly displayed. It can be remarkably prevented that the whole sentence meaning is easily guessed or grasped.
[0068]
By the way, in this cellular phone 1, not all characters in the text not designated by the character clear display window WND are displayed on the display unit 7 at all, but all the characters in the text not designated are displayed. Is displayed in a concealed state (for example, see FIG. 12). Thus, the user who reads the text by moving the character clear display window WND as appropriate can always know which position in the whole text of the received mail is being read. And can be read efficiently.
[0069]
According to the above configuration, of the plurality of characters constituting the body of the e-mail, only some characters designated by the character clarity display window WND are clearly displayed and the remaining characters are hidden and displayed. By doing so, even if the display unit 7 is peeped by another person other than the user who is operating the mobile phone 1, the content of the text is easily estimated or grasped. And can be surely prevented.
[0070]
As a result, the user of the mobile phone 1 can read or create the text without feeling uneasy about the content of the text of the e-mail leaking to other people around.
[0071]
In the mobile phone 1 according to the present embodiment, since there is no need to attach a polarizing plate for narrowing the viewing angle to the display unit 7 as in the conventional case, the mobile phone can improve confidentiality and display text. The telephone 1 can be realized with a simple configuration.
[0072]
In the cellular phone 1 according to the present embodiment, the size of the character clear display window WND can be changed to any size by the user by executing the window size changing process. Thereby, the user can increase or decrease the number of characters clearly displayed on the display unit 7, for example, to increase the number of characters to be clearly displayed with emphasis on readability, Alternatively, for the purpose of increasing the level of confidentiality, the number of characters to be clearly displayed can be reduced. As a result, it is possible to remarkably improve the usability of the mobile phone 1 that can improve confidentiality and display the text of an e-mail.
[0073]
Further, in the cellular phone 1 according to the present embodiment, when the jog dial 10 is rotated upward or downward during the text display processing for displaying the text of the received mail, the character corresponding to the rotational operation is displayed. The clear display window WND is moved upward or downward. As a result, the user can intuitively move the clear text display window WND in the text display screen 70, so that the text of the e-mail can be read easily and comfortably.
[0074]
(5) Other embodiments
In the above-described embodiment, the case where the text of the e-mail being created by the user is displayed on the display unit 7 or the case where the text of the received mail is displayed on the display unit 7 has been described. The invention is not limited to this. For example, in a mobile phone having a web browsing function for browsing a web page, when a sentence described on the web page is displayed on the display unit, or for inputting a memo In a mobile phone having a memo pad function, it is applied to display various other texts on the display unit, such as when displaying a memo input by the user via the operation unit on the display unit. Anyway.
[0075]
Further, in the above-described embodiment, among the plurality of characters constituting the body of the e-mail, characters not designated by the character clear display window WND are used as the background color (or the body display screen 70) of the background color ( For example, a case has been described in which the character that is not designated is concealed by displaying it with a character color (for example, light gray) approximated to white). However, the present invention is not limited to this, for example, a character clear display window. Characters not specified by the WND are hidden and displayed with the same character color (in this case, white) as the background color of the text creation screen 60 (or text display screen 70), or, for example, as shown in FIG. In addition, a character not specified by the character clear display window WND is replaced by a symbol such as “*” / other characters to be concealed. It may be Shimesuru so. In this case, since the character not designated by the character clear display window WND is not visually recognized, the secrecy can be remarkably improved.
[0076]
In addition, the present invention is not limited to this. For example, as shown in FIG. 13B, when the body of an e-mail is created, the character group GRP1 after the kanji conversion is confirmed and the kanji conversion is confirmed is created. It is also possible to scroll out of the screen 60 and display only the character group GRP2 before the kanji conversion confirmation is clearly displayed on the text creation screen 60. In this case, since the character group GRP1 after the kanji conversion is confirmed is not displayed on the body creation screen 60, that is, completely hidden, the concealment can be remarkably improved.
[0077]
Furthermore, the present invention is not limited to this. For example, as shown in FIG. 14, a character group GRP3 that is not designated by the character clear display window WND among a plurality of characters constituting the body of the e-mail (FIG. 14A). ) (Ie, “Good morning! It ’s a good weather today” and “So” meaning) and a different meaning (for example, “Fellowship to parents who went home in Amagasaki City, Niigata Prefecture”) And the character group GRP4 (FIG. 14B) representing the meaning and “memory”), the character group GPR3 may be replaced and concealed. In this case, even if the text display screen 70 shown in FIG. 14B is peeped by another person other than the user, the content of the text of the real e-mail is not understood. Confidentiality can be improved. At this time, by making the other person read the character group GRP4 instead of the original character group GRP3, it is possible to give an impression as if the peeping is successful. Thereby, since it is possible not to notice that the e-mail is displayed in the secret mode, it is possible to prevent receiving extra attention from the other person.
[0078]
Furthermore, in the above-described embodiment, the case where a sentence composed of a plurality of characters (that is, the body of an e-mail) is described in Japanese is described. However, the present invention is not limited to this, and other languages and symbols are used. Etc.
[0079]
Further, in the above-described embodiment, among the plurality of characters constituting the text of the e-mail, the characters before being converted to Kanji and the characters being converted to Kanji are clearly displayed, and the characters after the confirmation of Kanji conversion are concealed However, the present invention is not limited to this. For example, in the case of performing various other character conversions such as character conversion from hiragana to katakana or from uppercase to lowercase, Of the plurality of characters constituting the sentence, the character before character conversion and the character under character conversion may be clearly displayed to conceal the character after character conversion is confirmed.
[0080]
Further, in the above-described embodiment, when the text of the received mail is displayed on the display unit 7, the character clear display window WND in the text display screen 70 is displayed in accordance with the vertical rotation operation on the jog dial 10.
