  Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described with reference to the drawings.

  FIG. 1 shows a block diagram of a configuration of an embodiment of a mobile terminal to which a display deletion apparatus according to the present invention is applied. In FIG. 1, the mobile terminal includes a display unit 10, an operation unit 12, a storage unit 14, a time measurement unit 16, a communication unit 18, and a control unit 20.

  The display unit 10 is composed of, for example, a liquid crystal display or the like, and displays key input contents such as character data, various graphics, and the like. The key input is performed by the operation unit 12 shown in FIG. This operation part 12 is comprised by the operation button etc. of a portable terminal, for example.

  The storage unit 14 includes, for example, a working RAM of the control unit 20, an EEPROM as a nonvolatile memory, a magnetic storage medium, and the like, and stores various data such as key input contents.

  The time measuring unit 16 includes a time measuring function such as a clock, and generates time data necessary for controlling the portable terminal.

  The communication unit 18 communicates with the base station by a known method to realize a call function as a mobile communication terminal. When the present invention is applied to a PDA (Personal Digital Assistance) or the like, the communication unit 18 is not necessary.

  The control unit 20 includes, for example, a CPU, and controls these operations while exchanging data with the display unit 10, the operation unit 12, the storage unit 14, the time measurement unit 16, and the communication unit 18.

  The display control unit 22 of the control unit 20 mainly controls the content displayed on the display unit 10. The operation instruction unit 24 performs control for causing the mobile terminal to perform operations such as screen display that prompts the user to perform a predetermined operation such as displaying a pop-up menu screen for selecting a deletion process to be described later. The determination unit 26 performs control for executing determination necessary for control of the mobile terminal, such as whether or not a predetermined key is pressed by the user. The time management unit 28 acquires time data generated by the time measurement unit 16 and performs control for managing time data necessary for controlling the mobile terminal such as a time after a predetermined key is pressed. The character position management unit 30 performs control for managing the position data of each character in the text displayed on the screen of the display unit 10.

  FIG. 2 shows an example of the storage area of the storage unit 14 used by the character position management unit 30 for managing the position data of characters deleted by the clear key of the operation unit 12. In FIG. 2, the storage unit 14 includes four storage areas M1, M2, M3, and M4. In each storage area, deleted character data and position data of the character in the sentence are stored. It is comprised so that. The storage unit 14 in this case corresponds to a storage unit according to the present invention that stores data indicating deleted characters together with position information in the sentence for each character. FIG. 2 shows an example in which four storage areas M1, M2, M3, and M4 are provided. However, the number is not limited to four, and the number can be determined as appropriate.

  FIG. 3 and FIG. 4 are flowcharts showing the operation when the input character data is deleted in the display deletion apparatus described above. The flow described below may be realized by the CPU executing a program stored in the medium.

  In FIG. 3 and FIG. 4, when a desired character for displaying a sentence or the like on the display unit 10 is being input and a clear key for deleting the input character is pressed (S1), The time management unit 28 acquires the current time from the time measurement unit 16 and stores it in the area x of the storage unit 14 (S2). Further, the character position management unit 30 stores one character deleted by pressing the clear key in the area M1 of the storage unit 14 together with the position of the character in the sentence (S3).

  When the clear key is pressed again (S4), the character position management unit 30 stores one character deleted by pressing the clear key in the area M2 of the storage unit 14 together with the position in the sentence (S5). . Further, when the clear key is pressed (S6), the character position management unit 30 stores one character deleted by pressing the clear key in the area M3 of the storage unit 14 together with the position in the sentence (S7).

  Next, when the fourth clear key is pressed (S8), the time management unit 28 acquires the current time from the time measurement unit 16 and stores it in the area y of the storage unit 14 (S9). Here, the determination unit 26 determines whether the difference between the time stored in x and the time stored in y, that is, the time to delete four characters is within a predetermined value, for example, less than one second (S10), 1 If it is less than a second, the character position management unit 30 stores one character deleted by pressing the clear key in the area M4 of the storage unit 14 together with the position in the sentence (S11).

  If no clear key is pressed in S4, S6, or S8, or if the difference between the time stored in x and the time stored in y is 1 second or more in S10, a pop-up menu described later is used. An erasing process is executed (S22).

  Next, a pop-up menu creation process is executed by the operation instruction unit 24 (S12). The pop-up menu is created based on FIG. 5, FIG. 6, and FIG. 7, which will be described later, according to the position of the character deleted by the clear key in the sentence. In this case, the operation instruction unit 24 functions as a display unit and a display change unit according to the present invention. In the pop-up menu, for example, the items “stop”, “paragraph erase”, “sentence erase”, and “line erase” are displayed simultaneously on the screen of the display unit 10 during character data input (S13). . “Cancel” is a process that does not execute any of the “paragraph erase”, “text erase”, and “line erase” processes in the pop-up menu. "Paragraph erase" deletes the paragraph (character string between the cursor position and the line feed position immediately after it or all the character strings in the paragraph) that contained the deleted character in the entered text. It is processing. “Sentence erasure” is a process of deleting a sentence (character string between the punctuation marks) that includes the deleted character in the inputted sentence. “Line erase” is a process of deleting a line (character string of one line sentence displayed on the screen) in which a deleted character is included in a sentence being input.

  Next, the determination unit 26 determines whether or not the up / down key or the center key, that is, the key for selecting an item in the pop-up menu is pressed (S14). When a key other than the up / down key or the center key is pressed, a process corresponding to the pressed key is executed after a pop-up menu erasing process to be described later is executed (S22).

  On the other hand, when the up / down key or the center key is pressed, the determination unit 26 determines whether or not “cancel” in the pop-up menu is selected (S15). When “CANCEL” is selected, a pop-up menu deletion process is executed (S22). If “cancel” is not selected, the determination unit 26 determines whether “paragraph erase” in the pop-up menu is selected (S16). If “paragraph erase” is selected, the above-described paragraph erase processing is executed (S17). If “paragraph erase” is not selected, the determination unit 26 determines whether “text erase” in the pop-up menu is selected (S18). If “text erase” is selected, the text erase process described above is executed (S19). If “text erase” is not selected, the determination unit 26 determines whether “line erase” in the pop-up menu is selected (S20). If “line erasure” is selected, the line erasure process described above is executed (S21).

  Here, when “delete” is not selected and, for example, the delete key is pressed, the pop-up menu is deleted by the operation instruction unit 24 and the display of the pop-up menu is deleted from the screen of the display unit 10. (S22).

  Next, the character position management unit 30 releases the areas M1, M2, M3, and M4 of the storage unit 14 (S23).

  As described above, when the number of characters deleted by the clear key reaches a predetermined number (four characters in this embodiment), a pop-up menu for selecting a process to be executed thereafter is displayed. Can be made more efficient. As described above, the number of deleted characters until the pop-up menu is displayed is not limited to four characters, and can be determined as appropriate.

  5, 6, and 7 show an example of the pop-up menu creation process described in S <b> 12. FIG. 5 shows an example of the processing A, and the determination unit 26 determines whether or not the erased characters stored in the M1, M2, M3, and M4 cover two or more paragraphs of the sentence displayed on the screen. (S24) If there are more than two paragraphs, the display of “paragraph erase” is moved to the end (the position farthest from the default cursor position as the selection position in the pop-up menu) (S25). This is because if there are two or more erased characters, the possibility of deleting all the paragraphs containing the characters is low. If it is not over two paragraphs, process A is terminated.

  Next, FIG. 6 shows an example of the process B, and whether or not the erased characters stored in the M1, M2, M3, and M4 by the determination unit 26 extend over two or more sentences on the screen. (S26) If there are two or more sentences, the display of “text erase” is moved to the end (the position farthest from the default cursor position as the selection position in the pop-up menu) (S27). This is because if there are two or more erased characters, there is a low possibility of deleting all the sentences containing the characters. If it is not over two sentences, process B is terminated.

  Further, FIG. 7 shows an example of the process C, and whether or not the erased characters stored in the M1, M2, M3, and M4 by the determination unit 26 extend over two or more lines of the text displayed on the screen. Is determined (S28), and if there are two or more lines, the display of “line erase” is moved to the end (the position farthest from the default cursor position as the selection position in the pop-up menu) (S29). This is because if there are two or more erased characters, there is a low possibility of deleting all the lines containing the characters. If it is not over two paragraphs, process C is terminated.

  8, 9, 10 and 11 show examples of screens displayed on the display unit 10. FIG. FIG. 8 shows an example of the mail editing screen, which shows a case where the part “From 1:00 pm tomorrow” pointed out by the arrow (1) is deleted.

  As shown by the arrow (2) in FIG. 9, when the four characters up to “Tomorrow” are deleted by the clear key, the pop-up menu creation process described above is executed, and the arrow (3) in FIG. Pop-up menu is displayed on the screen. Here, for example, when “sentence erase” is selected, as indicated by an arrow (4) in FIG. 11, a sentence (character string between punctuation marks) that includes the deleted character is deleted.

  As described above, it is possible to improve the efficiency of deleting characters.
