This application claims the priority benefit of Korean Patent Application No. 10-2017-0043776, filed Apr. 4, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference for all purposes.
One or more example embodiments relate to a device and method for digital painting.
Amid the proliferation of mobile devices, many offline methods have become digitalized. For example, there is a method by which, when a user uses a pen-shaped tool in a mobile device as if the user writes a letter with an actual pen on a hand, the letter is expressed on an electronic device.
A user may draw or paint a picture on a canvas after placing colors on a palette and putting a desired color on a brush. This is a basic method that is used to draw or paint a picture, and people of all ages and both genders may paint a picture in such a way without an additional instruction, only if they have a palette, a brush, and a canvas.
However, there is still a lack of technology to digitalize such an actual method. Therefore, there is a desire for technology for digitally and intuitively painting a picture using a palette, a brush, and a canvas.
An aspect provides a method of expressing or depicting a picture or a letter on an electronic canvas formed of a light-emitting module, by using an electronic brush and an electronic palette.
Another aspect also provides a method of allowing a user to intuitively express or depict a picture or a letter using an electronic brush, an electronic palette, and an electronic canvas, and thus providing the user with a user experience (UX) from which the user feels as if the user dips into a color on a palette and paints a picture on a canvas with a brush.
According to an aspect, there is provided a digital painting device including 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.
According to another aspect, there is provided a digital painting method including 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.

The digital painting device 110 may be connected to the electronic brush 120 through wireless communication, but not limited thereto. The digital painting device 110 may be included in the electronic brush 120. Herein, the wireless communication may be short-range wireless communication, such as, for example, Bluetooth, magnetic secure transmission (MST), beacon, near-field communication (NFC), and WiFi.
The digital painting device 110 may generate a color generation signal corresponding to color data. The color generation signal refers to a signal that allows a color corresponding to the color data to be displayed on the electronic palette 130 or the light-emitting module 140.
The digital painting device 110 may transmit the generated color generation signal to the light-emitting module 140 through the electronic brush 120 such that the color data is displayed on the light-emitting module 140. Herein, the digital painting device 110 may transmit the color generation signal to the light-emitting module 140 where the electronic brush 120 approaches or touches.
The digital painting device 110 may register the electronic palette 130 including a plurality of sets of color data. Herein, the digital painting device 110 may register the electronic palette 130 by transmitting the sets of color data through the electronic brush 120. The electronic palette 130 may be included in the light-emitting module 140, or included in a mobile device (not shown).
The light-emitting module 140 may be a light-emitting diode (LED), and a plurality of light-emitting modules may be arranged to be embodied in a form of an electronic canvas.
The digital painting device 110 will be described in greater detail with reference to
Referring to
The generator 210 may generate a color generation signal corresponding to color data in an electronic palette selected by an electronic brush. That is, the generator 210 may generate a color generation signal for at least one color selected from a plurality of sets of color data included in the electronic palette. For example, when a red color is selected from the electronic palette including the red color, a yellow color, and a blue color, the generator 210 may generate a color generation signal indicating the selected red color.
In addition, the generator 210 may detect a motion through the electronic brush, and generate the color generation signal when the detected motion corresponds to a preset motion in a preset range. That is, the generator 210 may detect the motion occurring by a movement of the electronic brush through a motion sensor. When the motion corresponds to the preset motion, the generator 210 may determine that color data desired by a user is selected, and generate a corresponding color generation signal. For example, when the generator 210 detects a motion of the electronic brush shaking two times within a preset range after color data of a red color is selected by the electronic brush, the generator 210 may determine that the motion indicates generation of a corresponding color generation signal, and generate the color generation signal.
In addition, when a plurality of sets of color data is selected by the electronic brush during a time period, the generator 210 may 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. That is, when different sets of color data are selected in a time, the generator 210 may mix the selected sets of color data and generate a corresponding mixed color generation signal. For example, when color data selected within three seconds indicate a red color and a yellow color, the generator 210 may generate a mixed color generation signal indicating an orange color.
Further, when a plurality of sets of color data is selected by the electronic brush during the time period, the generator 210 may generate a plurality of color generation signals respectively corresponding to the selected sets of color data. That is, when a plurality of sets of color data is selected within a preset time, the generator 210 may generate a plurality of color generation signals respectively corresponding to the selected sets of color data. For example, when sets of color data are selected in a sequential order of a red color, a yellow color, and a blue color, in a preset time period, for example, three seconds, the generator 210 may generate corresponding color generation signals in the sequential order of the red color, the yellow color, and the blue color.
Herein, the displayer 220 may transmit the color generation signals in the sequential order each time the electronic brush touches a light-emitting module. That is, the displayer 220 may transmit the color generation signals to a plurality of light-emitting modules coming into contact with the electronic brush in a sequential order of the generated color generation signals, and allow corresponding color data to be displayed. For example, when the electronic brush sequentially touches a first light-emitting module, a second light-emitting module, and a third light-emitting module based on color generation signals generated in an order of a red color, a yellow color, and a blue color, the displayer 220 may transmit a color generation signal indicating the red color to the first light-emitting module, a color generation signal indicating the yellow color to the second light-emitting module, and a color generation signal indicating the blue color to the third light-emitting module.
The displayer 220 may transmit the color generation signal to the 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. That is, the displayer 220 may transmit the color generation signal to the light-emitting module that is touched by the electronic brush within a certain time period, and allow the light-emitting module receiving the color generation signal to display the color data. For example, when the color generation signal indicates a red color and the time period in which the color generation signal is maintained is three seconds, the displayer 220 may transmit the color generation signal indicating the red color to the light-emitting module that is to be touched in three seconds after the red color is selected by the electronic brush and the color generation signal indicating the red color is generated. Herein, the light-emitting module to which the displayer 220 transmits the color generation signal may be provided as a plurality of light-emitting modules. In the example described in the foregoing, the light-emitting module receiving the color generation signal may display the red color.
In addition, 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 220 may cause the light-emitting module to blink one or more times. That is, when it is verified that the color generation signal generated through the electronic brush and a color generation signal to be transmitted to the light-emitting module differ from each other, the displayer 220 may allow the light-emitting module to blink one or more times such that a user may recognize such a verification. For example, when the color data selected by the electronic brush indicates a red color and the color data to be displayed on the light-emitting module indicates a yellow color, the displayer 220 may allow the light-emitting module to blink.
According to an example, when the color data selected by the electronic brush and the color data to be displayed on the light-emitting module differ from each other, the displayer 220 may allow a dominant set of color data among sets of color data indicated on neighboring light-emitting modules around the light-emitting module to be displayed, and allow the light-emitting module to blink one or more times. For example, when a red color is selected by the electronic brush and it is verified that a yellow color is displayed on a first light-emitting module among a plurality of light-emitting modules that is touched by the electronic brush, the displayer 220 may allow, to be displayed on the first light-emitting module, color data indicating the red color and displayed on light-emitting modules positioned on a left side, a right side, an upper side, and a lower side of the first light-emitting module, and allow the first light-emitting module to blink one or more times. For another example, when a red color is selected by the electronic brush and a yellow color is displayed on a first light-emitting module that is touched by the electronic brush, and light-emitting modules positioned on left, upper, and lower sides of the first light-emitting module display an orange color and a light-emitting module positioned on a right side of the first light-emitting module displays the red color, the displayer 220 may allow the first light-emitting to display the orange color, which is a more dominant color. In this example, when the number of colors displayed on the light-emitting modules positioned on the left, right, upper, and lower sides is all same, the displayer 220 may allow the first light-emitting module to display a color of priority based on a preset standard, for example, an order in which the colors are used, an order in which the colors are stored, a name order of the colors, and the like.
Herein, when the light-emitting module is touched by the electronic brush while the light-emitting module is blinking, the displayer 220 may retransmit the color generation signal to the light-emitting module, and allow the color data to be displayed on the light-emitting module. That is, the displayer 220 may retransmit a color generation signal to a light-emitting module retouched by the electronic brush, and allow color data desired by a user to be displayed. For example, when a light-emitting module displaying a yellow color blinks, the displayer 220 may transmit a color generation signal that indicates a red color and is generated through the electronic brush to the light-emitting module when the light-emitting module is retouched by the electronic brush, and stop the light-emitting module from blinking when the red color is displayed on the light-emitting module because the electronic brush and the light-emitting module indicate the same color data.
When the time period elapses, the processor 230 may output a phrase that expresses inquiry as to whether to store the color generation signal, and store the color generation signal along with the color data in a database based on a command input by a user reading the phrase. That is, when the color generation signal generated through the electronic brush is maintained for a preset time period, the processor 230 may output such an inquiry as to whether to store the color generation signal. Herein, when the user gives a command indicating “store,” the processor 230 may store the color generation signal and the color data in the database. Herein, when the color generation signal generated through the electronic brush is a signal that is already stored in the database, the processor 230 may not output the phrase inquiring whether to store the color generation signal even though the time period elapses.
In addition, the processor 230 may receive a color from a user, and extract color data of the received color from the database and register the extracted color data in the electronic palette. Herein, when the number of extracted sets of color data is greater than the number of allowable sets of color data to be registered in the electronic palette, the processor 230 may register at least a portion of the extracted sets of color data in the electronic palette based on a frequency of use. For example, when the user inputs a red color, a yellow color, and a blue color, the processor 230 may register, in the electronic palette, color data indicating each of the red color, the yellow color, and the blue color. For example, when the user inputs six colors although the number of the allowable sets of color data to be registered in the electronic palette is five, the processor 230 may register, in the electronic palette, five sets of color data with a higher frequency of use. In addition, the processor 230 may receive an input requesting correction or modification of a configuration of the electronic palette from the user, and correct or modify the configuration of the electronic palette by, for example, removing or registering color data from or in the electronic palette in response to the received input requesting the correction or modification.
Thus, the digital painting device 200 may express a picture or a letter by allowing the picture or the letter to be displayed on an electronic canvas formed of a light-emitting module, using the electronic brush and the electronic palette described above.
In addition, the digital painting device 200 may allow a user to intuitively express a picture or a letter using the electronic brush, the electronic palette, and the electronic canvas, and thus may provide the user with a user experience (UX) from which the user may feel as if the user actually paints a picture on a canvas by dipping into a color on a palette with a brush.
In addition, the digital painting device 200 may mix desired colors among sets of color data included in the electronic palette, or display the colors on the electronic canvas in an order in which the colors are selected. Thus, the digital painting device 200 may enable an expression method different from a traditional one, thereby allowing a user to paint or draw a picture in a user's own way of expression using the different expression method.
Further, the digital painting device 200 may digitally paint a picture by allowing a user to paint a picture in a traditional way that the user paints a picture on a canvas using a brush and colors on a palette. Thus, the digital painting device 200 may enable all users including children and elderly users who may have difficulty in handling electronic devices to paint or draw pictures that they desire to express. Thus, it is expected that the digital painting device 200 may attract great attention and be used as hands-on learning play tools in exhibitions or educational fields.
The digital painting device 200 may be included in an electronic brush 330 illustrated in
Referring to
An electronic palette 320 may be positioned in the electronic canvas 310. For example, the electronic brush 330 may register a plurality of sets of color data 321, 322, and 323 in a portion of the electronic canvas 310 to configure the electronic palette 320. When at least one set of the sets of color data 321, 322, and 323 is selected from the electronic palette 320, the electronic brush 330 may generate a color generation signal corresponding to the selected color data.
For example, the digital painting device 200, or the electronic brush 330, may position the electronic palette 320 on the electronic canvas 310 including the light-emitting modules 311, select at least one set of the sets of color data 321, 322, and 323 from the electronic palette 30 including desired colors and generate a color generation signal corresponding to the selected color data, and then transmit the color generation signal to the light-emitting modules 311 in the electronic canvas 310. The light-emitting modules 311 may then illuminatingly display a color of the color data based on the color generation signal.

The digital painting method to be described hereinafter with reference to
Referring to
In operation 1220, the digital painting device 200 transmits 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 to. That is, the digital painting device 200 may transmit the color generation signal to the light-emitting module that touches the electronic brush within a certain period of time, and allow the light-emitting module receiving the color generation signal to display the color data. For example, when the color generation signal indicates a red color and the time period in which the color generation signal is maintained is three seconds, the digital painting device 200 may transmit the color generation signal indicating the red color to the light-emitting module that is to be touched within three seconds after the red color is selected by the electronic brush and the color generation signal indicating the red color is generated. In this example, the light-emitting module may be provided as a plurality of light-emitting modules, and the light-emitting module receiving the color generation signal among the light-emitting modules may display the red color.
According to an example, when a plurality of sets of color data is selected by the electronic brush during the time period, the digital painting device 200 may 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 lieu of the color generation signal. That is, when a plurality of different sets of color data is selected in a certain period of time, the digital painting device 200 may generate a mixed color generation signal by mixing the selected sets of color data. For example, when sets of color data corresponding to a red color and a yellow color are selected in three seconds, the digital painting device 200 may generate a mixed color generation signal indicating an orange color.
According to an example, when a plurality of sets of color data is selected by the electronic brush during the time period, the digital painting device 200 may generate a plurality of color generation signals respectively corresponding to the selected sets of color data. That is, when a plurality of sets of color data is selected in a certain period of time, the digital painting device 200 may generate a color generation signal corresponding to each of the selected sets of color data. For example, when sets of color data are selected in an order of a red color, a yellow color, and a blue color in three seconds, which is a preset time period, the digital painting device 200 may generate corresponding color generation signals in an order of the red color, the yellow color, and the blue color.
Herein, the digital painting device 200 may sequentially transmit the generated color generation signals each time the electronic brush touches the light-emitting modules. That is, the digital painting device 200 may transmit the color generation signals in an order in which the color generation signals are generated to the light-emitting modules that the electronic brush touches. For example, when the electronic brush in which the color generation signals are generated in an order of a red color, a yellow color, and a blue color touches a first light-emitting module, a second light-emitting module, and a third light-emitting module in sequential order, the digital painting device 200 may transmit a color generation signal indicating the red color to the first light-emitting module, a color generation signal indicating the yellow color to the second light-emitting module, and a color generation signal indicating the blue color to the third light-emitting module.
According to an example, when the time period elapses, the digital painting device 200 may output a phrase that expresses an inquiry as to whether to store the color generation signal, and store the color generation signal along with the color data in a database based on a command input by a user reading the phrase. That is, the digital painting device 200 may output the phrase during a preset period of time in which the color generation signal generated in the electronic brush is maintained. For example, when the user gives a command indicating “store,” the digital painting device 200 may store the color generation signal and the color data in the database. In this example, when the color generation signal generated in the electronic brush is a signal that is already stored in the database, the digital painting device 200 may not output such a phrase inquiring whether to store the color generation signal even though the time period elapses.
According to an example, 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 digital painting device 200 may allow the light-emitting module to blink one or more times. That is, when it is verified that the color generation signal generated in the electronic brush and a color generation signal transmitted to the light-emitting module differ from each other, the digital painting device 200 may allow the user to recognize the difference by allowing the light-emitting module to blink one or more times. For example, when the color data selected by the electronic brush indicates a red color and the color data displayed on the light-emitting module indicates a yellow color, the digital painting device 200 may allow the light-emitting module to blink.
According to an example, when the color data selected by the electronic brush and the color data to be displayed on the light-emitting module differ from each other, the digital painting device 200 may allow the light-emitting module to display dominant color data among sets of color data displayed on neighboring light-emitting modules around the light-emitting module, and allow the light-emitting module to blink one or more times. For example, when a red color is selected by the electronic brush and a yellow color is displayed on a first light-emitting module among a plurality of light-emitting modules that is touched by the electronic brush, the digital painting device 200 may allow the first light-emitting module to display color data that corresponds to the red color and is displayed on neighboring light-emitting modules positioned on upper, lower, left, and right sides of the first light-emitting module, and allow the first light-emitting module to blink plural times. For another example, when a red color is selected by the electronic brush and a yellow color is displayed on a first light-emitting module that is to be touched by the electronic brush, and light-emitting modules positioned on the upper, lower, and left sides of the first light-emitting module display an orange color and a light-emitting module positioned on the right side of the first light-emitting module displays the red color, the digital painting device 200 may allow the first light-emitting module to display the orange color, which is the more dominant color. Also, in this example, when the numbers of colors of the light-emitting modules positioned on the upper, lower, left, and right sides are the same, the digital painting device 200 may allow a color of priority to be displayed based on a preset standard, for example, an order in which the colors are used, an order in which the colors are stored, and a name order of the colors.
According to an example, when a light-emitting module is touched by the electronic brush while the light-emitting module is blinking, the digital painting device 200 may retransmit a color generation signal to the light-emitting module such that the light-emitting module may display color data corresponding to the color generation signal. That is, the digital painting device 200 may retransmit a color generation signal to a light-emitting module that is retouched by the electronic brush such that color data desired by a user may be displayed. For example, when a light-emitting module displaying a yellow color is blinking and the electronic brush touches again the light-emitting module, the digital painting device 200 may retransmit a color generation signal generated by the electronic brush, for example, a color generation signal indicating a red color, to the light-emitting module. When the red color is displayed on the light-emitting module, the electronic brush and the light-emitting module may indicate the same color data, and thus the digital painting device 200 may stop the light-emitting module from blinking.
According to an example, the digital painting device 200 may receive, as an input, a color from a user, extract color data corresponding to the color from a database, and register the extracted color data in the electronic palette. Herein, when the number of extracted sets of color data is greater than the number of allowable sets of color data to be registered in the electronic palette, the digital painting device 200 may register at least a portion of the extracted sets of color data in the electronic palette based on a frequency of use. For example, when the user inputs colors, for example, a red color, a yellow color, and a blue color, the digital paining device 200 may register sets of color data respectively corresponding to the red color, the yellow color, and the blue color in the electronic palette. For example, when the user inputs six colors, although the number of the allowable sets of color data to be registered in the electronic palette is five, the digital painting device 200 may register, in the electronic palette, five sets of color data that have higher frequencies of use. In addition, the digital painting device 200 may receive, from a user, an input indicating correction or modification of a configuration of the electronic palette, and then correct or modify the configuration of the electronic palette by removing or registering, from or in the electronic palette, an individual set of color data corresponding to the input indicating the correction or modification.
According to an example, the digital painting device 200 may detect a motion through the electronic brush, and generate a corresponding color generation signal when the detected motion corresponds to a preset motion in a preset range. That is, the digital painting device 200 may detect the motion taken through a movement of the electronic brush using a sensor, and generate the color generation signal by determining that color data desired by the user is selected when the detected motion corresponds to the preset motion. For example, when color data of a red color is selected by the electronic brush and then a motion of the electronic brush shaking two times within a preset range is detected, the digital painting device 200 may determine that the motion indicates generation of a color generation signal, and generate the color generation signal.
As described above, the digital painting method may express a picture or a letter on an electronic canvas including a light-emitting module, using an electronic brush and an electronic palette.
In addition, the digital painting method may allow a user to intuitively express a picture or a letter using the electronic brush, the electronic palette, and the electronic canvas, and thus may provide the user with an UX from which the user may feel as if the user actually paints a picture on a canvas by dipping into a color on a palette with a brush.
In addition, the digital painting method may mix desired colors among sets of color data included in the electronic palette, or allow the colors to be displayed on the electronic canvas in an order in which the colors are selected, thereby enabling an expression method different from a traditional one and allowing a user to paint a picture in a user's own way of expression using the different expression method.
Further, the digital painting method may digitally paint a picture by allowing a user to paint the picture in a traditionally way that the user paints or draws the picture on a canvas using a brush and colors. Thus, the digital painting method may enable all users including children and elderly users who may have difficulty in handling electronic devices to paint or draw pictures that they desire to express. Thus, it is expected that the digital painting method may attract great attention and be used as hands-on learning play tools in exhibitions or educational fields.
According to example embodiments described herein, by allowing a user to express or depict a picture or a letter on an electronic canvas formed of a light-emitting module using an electronic brush and an electronic palette, the user may express the picture or the letter on the electronic canvas.
