Abstract

Provided are an image forming apparatus with a touchscreen and a method of editing input letters using the same. In the method, an inputted text is displayed on the touchscreen using keys of the soft keyboard. A letter to be edited is received from the displayed text. At least one of coordinates representing adjacent keys of the soft keyboard is determined based on a coordinate corresponding to a location of the received letter on the touchscreen. At least one of the magnified images of the adjacent keys corresponding to the determined coordinates and functions keys is displayed. The displayed text is edited using a letter corresponding to one key that is selected from the magnified image of the adjacent keys.

Claims

1. A method of editing letters inputted through a touchscreen of an image forming apparatus with a soft keyboard, the method comprising:

displaying an input text on the touchscreen using keys of the soft keyboard;

receiving a letter to be edited from the displayed text;

determining at least one of coordinates representing adjacent keys of the soft keyboard based on a coordinate corresponding to a location of the received letter on the touchscreen;

displaying at least one of magnified images of the adjacent keys corresponding to the determined coordinates and function keys;

selecting a key from the magnified image of the adjacent keys; and

editing the displayed text using a letter corresponding to the selected key.

2. The method of claim 1, further comprising storing coordinates corresponding to locations of the respective letters of the inputted text on the touchscreen.

3. The method of claim 1, wherein the displaying of at least one of the magnified images and the function keys comprises displaying the magnified image to differentiate from the keys of the soft keyboard.

4. The method of claim 1, wherein the displaying of at least one of the magnified images and the function keys comprises displaying the magnified image to overlap the soft keyboard.

5. The method of claim 1, wherein the editing of the displayed text comprises correcting the displayed text using the letter corresponding to the selected key or inserting the letter corresponding to the selected key into the displayed text.

6. The method of claim 1, wherein the editing of the displayed text comprises editing the displayed text using a letter corresponding to a key of the soft keyboard that is selected instead of the magnified image.

7. The method of claim 1, further comprising removing the magnified images and the function keys after the displayed text is edited.

8. The method of claim 1, wherein the displaying of at least one of the magnified images and the function keys comprises changing adjacent keys displayed in the magnified image according to a predetermined range of the adjacent keys, presence or absence of the adjacent keys, or an error history comprising counting the typing errors of the input text, wherein the changing of adjacent keys is performed by a user.

9. The method of claim 1, wherein the displaying of at least one of the magnified images and the function keys comprises displaying magnified images comprising the input letter in the displayed text and adjacent keys corresponding to a certain number of letters on the right and left of the received letter.

10. The method of claim 1, wherein the displaying of the input text comprises displaying a letter input consecutively a predetermined number of times into the inputted text in different colors or patterns, and the displaying of at least one of the magnified images and the function keys comprises displaying magnified images of adjacent keys corresponding to the respective same letters in different color or patterns.

11. The method of claim 1, further comprising determining whether an edit mode is an overwrite mode or an insert mode after the letters to be edited are received, wherein the editing of the displayed text comprises editing the displayed text in a mode according to a result of the determination.

12. The method of claim 11, wherein the overwrite mode and the insert mode are switched between each other by performing at least one of a double click, a single click, a long click, and a toggle key click on the touchscreen

21. The method of claim 1, wherein the image forming apparatus performs at least one of print, copy, scan, fax and e-mail functions.

22. The method of claim 1, wherein the displaying of at least one of the magnified images and the function keys comprises displaying the magnified image not to overlap the soft keyboard.

23. The method of claim 1, further comprising determining at least one of coordinates representing adjacent keys of the soft keyboard based on a coordinate corresponding to a location of a letter adjacent to the received letter on the touchscreen.

24. The method of claim 1, further comprising determining whether the inputted text comprises a same letter inputted multiple times in a row;

and

if determined that the inputted text comprises a same letter inputted multiple times in a row, displaying a plurality of magnified images of the adjacent keys corresponding to the same letter.

25. The method of claim 1, wherein the selecting a key comprises touching the key on the soft keyboard.

13. An image forming apparatus to edit letters input, comprising:

a display unit comprising a touchscreen to display a soft keyboard and a text input through the soft keyboard and keys of the soft keyboard;

an input unit to receive a letter to be edited from the displayed text;

a coordinate processing unit to determine at least one of coordinates representing adjacent keys of the soft keyboard based on a coordinate corresponding to a location of the received letter on the touchscreen; and

a control unit controlling the display unit to display at least one of magnified images of the adjacent keys corresponding to the determined coordinates and functions keys and to edit the displayed text using a letter corresponding to one key that is selected from the magnified image of the adjacent keys.

14. The image forming apparatus of claim 13, further comprising a storage unit to store the coordinates corresponding to locations of the respective letters of the input text on the touchscreen.

15. The image forming apparatus of claim 13, wherein the display unit displays the magnified image to differentiate from the keys of the soft keyboard or displays the magnified image to overlap the soft keyboard.

16. The image forming apparatus of claim 13, wherein the control unit controls the display unit to display the magnified images of adjacent keys corresponding to the input letter of the display text and a certain number of letters on the right and left of the input letter.

17. The image forming apparatus of claim 13, wherein the display unit displays letters input consecutively a predetermined number to times into the input text in different colors or patterns, and the control unit controls the display unit to display the magnified images of adjacent keys corresponding to the respective same letters in different colors or patterns.

18. A method of editing letters input through a touchscreen with a soft keyboard, the method comprising:

displaying an input text on the touchscreen using keys of the soft keyboard;

receiving a letter to be edited from the displayed text;

determining at least one of coordinates representing adjacent keys of the soft keyboard based on a coordinate corresponding to a location of the received letter on the touchscreen;

displaying at least one of magnified images of the adjacent keys corresponding to the determined coordinates and functions keys; and

editing the displayed text using a letter corresponding to a key that is selected from the magnified image of the adjacent keys.

19. The method of claim 18, further comprising storing coordinates corresponding to locations of the respective letters of the inputted text on the touchscreen.

20. The method of claim 18, wherein the displaying of at least one of the magnified images and the function keys comprises displaying the magnified image to differentiate from the keys of the soft keyboard or displaying the magnified image to overlap the soft keyboard.

26. The method of claim 18, wherein the displaying of the magnified images further comprises displaying the letter to be edited and the adjacent keys in different colors or patterns;

and

displaying magnified images of letters adjacent to the letter to be edited and adjacent keys in different colors or patterns.
