Abstract

Methods and apparatus are provided for transmitting and receiving a calligraphed writing message. Writing data is receiving as input at a transmitting apparatus. The writing data is sampled to generate character frame data having a plurality of point data. Calligraphy control point data is generated using the character frame data. The calligraphed writing message including the calligraphy control point data is generated and transmitted to a receiving apparatus. A calligraphy outline is generated at the receiving apparatus for generation of a calligraphed writing image using the calligraphy control point data from the calligraphed writing message. Graphic processing is performed on the calligraphy outline. The calligraphed writing image is generated and displayed.

an input unit for receiving writing data;

a sampling unit for sampling the writing data to generate character frame data, wherein the character frame data comprises a plurality of point data;

a calligraphy unit for generating calligraphy control point data using the character frame data, wherein the calligraphy control point data is used to generate a calligraphed writing image; and

a controller for controlling the sampling unit to generate the character frame data when the writing data is received through the input unit, for controlling the calligraphy unit to generate the calligraphy control point data using the character frame data, for generating the calligraphed writing message comprising the calligraphy control point data, and for transmitting the calligraphed writing message to a receiving apparatus.

2. The apparatus as claimed in claim 1, further comprising a graphic processor for performing graphic processing, wherein the calligraphy unit generates a calligraphy outline surrounding the character frame data using the calligraphy control point data, and wherein the controller controls the graphic processor to perform the graphic processing on the calligraphy outline, generates the calligraphed writing image, and displays the calligraphed writing image on a screen.

3. The apparatus as claimed in claim 2, wherein the controller calculates an average value of lengths of stroke data included in the character frame data, determines whether the average value is less than or equal to a preset reference value, controls a ratio of the calligraphy outline to correspond to a size of the character frame data when the average value is less than or equal to the preset reference value, and controls the calligraphy unit to generate the calligraphy outline in accordance with the ratio.

4. The apparatus as claimed in claim 3, wherein the calligraphed writing message further comprises display information having position data of the calligraphy control point data and size information of a writing input region of the apparatus.

5. The apparatus as claimed in claim 1, wherein the input unit is for receiving text data, and wherein, when the text data is received at the input unit, the controller identifies a preset writing style in order to generate the calligraphed writing image corresponding to the text data, and detects the calligraphy control point data corresponding to the preset writing style.

6. The apparatus as claimed in claim 1, wherein, when the writing data is received at the input unit, the controller determines whether an input of a writing stroke of the writing data is completed, and, when the input of the writing stroke is completed, the controller performs calligraphy for the writing stroke, generates calligraphed writing stroke data, displays the calligraphed writing stroke data on a screen, and receives an input of a next writing stroke of the writing data through the input unit.

7. The apparatus as claimed in claim 6, wherein the controller divides the writing stroke into a plurality of stroke segments, performs the calligraphy according to the plurality of stroke segments, connects the plurality of calligraphed stroke segments, and generates the calligraphed writing stroke data.

8. An apparatus for receiving a calligraphed writing message, the apparatus comprising:

a calligraphy unit for generating a calligraphy outline for generation of a calligraphed writing image;

a graphic processor for performing graphic processing; and

a controller for controlling the calligraphy unit to generate the calligraphy outline using calligraphy control point data when the calligraphed writing message comprising the calligraphy control point data is received from a transmitting apparatus, controlling the graphic processor to perform the graphic processing on the calligraphy outline, generating the calligraphed writing image, and displaying the calligraphed writing image.

9. The apparatus as claimed in claim 8, wherein the calligraphed writing message further comprises display information having position data of the calligraphy control point data and size information of a writing input region of the transmitting apparatus.

10. The apparatus as claimed in claim 9, wherein the controller obtains size information of a writing display region of the apparatus, compares the size information of the writing input region and the size information of the writing display region, and controls the position data of the calligraphy control point data to fit a size of the writing display region when the size information of the writing input region and the size information of the writing display region are not identical.

11. A method of transmitting a calligraphed writing message in a transmitting apparatus, the method comprising the steps of:

sampling writing data to generate character frame data, when the writing data is input, wherein the character frame data comprises a plurality of point data;

generating calligraphy control point data using the character frame data, wherein the calligraphy control point data is used to generate a calligraphed writing image;

generating the calligraphed writing message comprising the calligraphy control point data; and

transmitting the calligraphed writing message to a receiving apparatus.

12. The method as claimed in claim 11, further comprising:

generating a calligraphy outline surrounding the character frame data using the calligraphy control point data;

generating the calligraphed writing image by performing graphic processing on the calligraphy outline; and

displaying the calligraphed writing image on a screen.

13. The method as claimed in claim 12, further comprising:

calculating an average value of lengths of stroke data included in the character frame data;

determining whether the average value is less than or equal to a preset reference value;

controlling a ratio of the calligraphy outline to correspond to a size of the character frame data when the average value is less than or equal to the preset reference value; and

generating the calligraphy outline in accordance with the ratio.

14. The method as claimed in claim 13, wherein the calligraphed writing message further comprises display information having position data of the calligraphy control point data and size information of a writing input region of the transmitting apparatus.

15. The method as claimed in claim 11, further comprising:

identifying a preset writing style in order to generate the calligraphed writing image corresponding to text data, when the text data is received; and
