Abstract

An apparatus and method for controlling a size of display data in a portable terminal are provided. The apparatus includes a controller for automatically controlling a size of display data according to a preset user'"'"'s reference eyesight. Accordingly, the size of displayed text can be automatically expanded or reduced in the portable terminal based on the user'"'"'s eyesight or a distance of the user.

Claims

1. An apparatus for controlling a size of display data in a portable terminal, the apparatus comprising:

a controller for automatically controlling a size of display data according to preset user'"'"'s reference eyesight.

2. The apparatus of claim 1, wherein the preset user'"'"'s reference eyesight comprises a user'"'"'s eyesight for the display data, and is set in such a manner that a user inputs information measured in an eyesight measurement institute.

3. The apparatus of claim 2, wherein the reference eyesight comprises a distance between the portable terminal and a specific part of the body, and the distance is measured by a sensor for measuring a distance with the body.

4. The apparatus of claim 2, wherein the reference eyesight is defined in the following table:

5. The apparatus of claim 1, wherein the controller determines a preset data display condition, determines if the display condition matches with the user'"'"'s reference eyesight, and changes the display condition suitable to the reference eyesight if the display condition does not match with the user'"'"'s reference eyesight.

6. The apparatus of claim 5, wherein, if the user'"'"'s eyesight is measured less than the reference eyesight, the controller expands the size of the display data, and

if the user'"'"'s eyesight is measured greater than the reference eyesight, the controller reduces the size of the display data.

7. A method for controlling a size of display data in a portable terminal, the method comprising:

automatically controlling a size of display data according to a preset user'"'"'s reference eyesight.

8. The method of claim 7, wherein the preset user'"'"'s reference eyesight comprises a user'"'"'s eyesight for the display data and is set in such a manner that a user inputs information measured in an eyesight measurement institute.

9. The method of claim 8, wherein the reference eyesight comprises a distance between the portable terminal and a specific part of the body, and the distance is measured by a sensor for measuring a distance with the body.

10. The method of claim 8, wherein the reference eyesight is defined in the following table:

11. The method of claim 7, wherein the automatically controlling of the size of the display data according to the preset user'"'"'s reference eyesight comprises:

determining a preset data display condition;

determining if the display condition matches with the user'"'"'s reference eyesight; and

if the display condition does not match with the user'"'"'s reference eyesight, changing the display condition suitable to the reference eyesight.

12. The method of claim 11, wherein the changing of the display condition suitable to the reference eyesight comprises:

if the user'"'"'s eyesight is measured less than the reference eyesight, expanding a size of display data; and

if the user'"'"'s eyesight is measured greater than the reference eyesight, reducing the size of the display data.

13. An apparatus for controlling a size of display data in a portable terminal, the apparatus comprising:

a display unit for displaying data;

a reference eyesight determining unit for measuring a user'"'"'s eyesight for the display data; and

a controller for changing a display condition of the data displayed on the display unit according to the measurement result of the reference eyesight determining unit.

14. The apparatus of claim 13, wherein the reference eyesight comprises a distance between the portable terminal and a specific part of the boy, and the distance is measured by a sensor for measuring a distance with the body.

15. The apparatus of claim 13, wherein the controller determines if a preset data display condition matches with the user'"'"'s reference eyesight and, if the display condition does not match with the user'"'"'s reference eyesight, the controller changes the display condition suitable to the reference eyesight.

16. The apparatus of claim 13, wherein, if user'"'"'s eyesight is measured less than the reference eyesight, the controller expands the size of the display data, and

if the user'"'"'s eyesight is measured greater than the reference eyesight, the controller reduces the size of the display data.
