Abstract

A digital painting device and method. The digital painting device includes a generator to generate a color generation signal corresponding to color data in an electronic palette selected by an electronic brush, and a displayer to transmit the color generation signal to a light-emitting module that touches the electronic brush in a time period in which the color generation signal is maintained such that the color data is displayed on the light-emitting module.

First claim

What is claimed is:

1 . A digital painting device comprising:
a generator configured to generate a color generation signal corresponding to color data in an electronic palette selected by an electronic brush; and a displayer configured to transmit the color generation signal to a light-emitting module being in contact with the electronic brush in a time period in which the color generation signal is maintained such that the color data is displayed on the light-emitting module.

2 . The digital painting device of claim 1 , wherein, when a plurality of sets of color data is selected by the electronic brush during the time period, the generator is configured to:
generate mixed color data by mixing the selected sets of color data; and generate a mixed color generation signal corresponding to the mixed color data, in place of the color generation signal.

3 . The digital painting device of claim 1 , wherein, when a plurality of sets of color data is selected by the electronic brush during the time period, the generator is configured to generate a plurality of color generation signals respectively corresponding to the selected sets of color data, and
the displayer is configured to sequentially transmit the generated color generation signals each time the electronic brush touches the light-emitting module.

4 . The digital painting device of claim 1 , further comprising:
a processor configured to output a phrase that expresses an inquiry as to whether to store the color generation signal when the time period elapses, and store the color generation signal along with the color data in a database based on a command by a user reading the phrase.

5 . The digital painting device of claim 1 , wherein, when the color data selected by the electronic brush and color data to be displayed on the light-emitting module differ from each other, the displayer is configured to allow the light-emitting module to blink one or more times.

6 . The digital painting device of claim 5 , wherein, when the electronic brush touches the light-emitting module while the light-emitting module is blinking, the displayer is configured to retransmit the color generation signal to the light-emitting module such that the color data is displayed on the light-emitting module.

7 . The digital painting device of claim 1 , further comprising:
a processor configured to: receive, as an input, a color from a user; and extract color data of the color from a database and register the extracted color data in the electronic palette,
wherein, when a number of extracted sets of color data is greater than a number of allowable sets of color data to be registered in the electronic palette, the processor is configured to register, in the electronic palette, at least a portion of the extracted sets of color data based on a frequency of use.

8 . The digital painting device of claim 1 , wherein, when a motion detected through the electronic brush corresponds to a preset motion in a preset range, the generator is configured to generate the color generation signal.

9 . A digital painting method comprising:
generating a color generation signal corresponding to color data in an electronic palette selected by an electronic brush; and transmitting the color generation signal to a light-emitting module being in contact with the electronic brush in a time period in which the color generation signal is maintained such that the color data is displayed on the light-emitting module.

10 . The digital painting method of claim 9 , when a plurality of sets of color data is selected by the electronic brush during the time period, further comprising:
generating mixed color data by mixing the selected sets of color data; and generating a mixed color generation signal corresponding to the mixed color data, in place of the color generation signal.

11 . The digital painting method of claim 9 , when a plurality of sets of color data is selected by the electronic brush during the time period, further comprising:
generating a plurality of color generation signals respectively corresponding to the selected sets of color data; and sequentially transmitting the generated color generation signals each time the electronic brush touches the light-emitting module.

12 . The digital painting method of claim 9 , further comprising:
outputting a phrase that expresses an inquiry as to whether to store the color generation signal when the time period elapses; and storing, in a database, the color generation signal along with the color data based on a command by a user reading the phrase.

13 . The digital painting method of claim 9 , when the color data selected by the electronic brush and color data to be displayed on the light-emitting module differ from each other, further comprising:
allowing the light-emitting module to blink one or more times.

14 . The digital painting method of claim 13 , when the electronic brush touches the light-emitting module while the light-emitting module is blinking, further comprising:
retransmitting the color generation signal to the light-emitting module such that the color data is displayed on the light-emitting module.

15 . The digital painting method of claim 9 , further comprising:
receiving, as an input, a color from a user; and extracting color data of the color from a database and registering the extracted color data in the electronic palette,
wherein, when a number of extracted sets of color data is greater than a number of allowable sets of color data to be registered in the electronic palette, the extracting of the color data and the registering of the color data comprises:
registering, in the electronic palette, at least a portion of the extracted sets of color data based on a frequency of use.

16 . The digital painting method of claim 9 , further comprising:
detecting a motion through the electronic brush; and generating the color generation signal when the detected motion corresponds to a preset motion in a preset range.
