Abstract

An electronic device according to various embodiments of the present invention includes: a touch screen display; a processor operatively connected to the display; and a memory operatively connected to the processor. The memory may include instructions which, when executed, cause the processor to: display, on the display, a user interface including a first section configured to receive a drawing input and a second section including a plurality of colors and one or more line widths, which are to be selected for the drawing input; execute an animation image file to be displayed on the first section, the animation image file including a procedure of drawing an object with at least one color among the plurality of colors and at least one line width among the one or more line widths; receive, from the display, an input for stopping the execution of the image file; and display a drawing output on the display according to the drawing input, the drawing output including at least one among the color and the line width used when the drawing input is received. Various other embodiments are also possible.

First claim

The invention claimed is:

1. An electronic device comprising:
a touchscreen display;
a processor operatively connected to the display; and
a memory operatively connected to the processor, wherein
the memory comprises instructions that, when executed, cause the processor to:
display, on the display, a user interface comprising a first section configured to receive a drawing input and a second section comprising multiple hues and one or more line widths to be selected for the drawing input;
execute an animation image file to be displayed on the first section, the animation image file comprising an order in which an object is drawn by using at least one hue among the multiple hues and at least one line width among the one or more line widths;
receive an input for stopping executing the image file from the display; and
display a drawing output on the display according to the drawing input, the drawing output comprising a hue and a line width used when the drawing input is received,

wherein the instructions are configured to cause the processor to display, on the second section, metadata associated with an image at a current playback time in the image file, and
wherein the metadata comprises information indicating a type of a drawing tool and information indicating a hue of the image.

2. The electronic device of claim 1 , wherein the instructions are configured to cause the processor to:
execute the image file so as to display a first animation of drawing a first part of the object by using a first hue and a first line width for a first duration period;
receive a first input for stopping execution of the image file for the first duration period; and
display a drawing output comprising the first hue and the first line width.

3. The electronic device of claim 2 , wherein the instructions are configured to cause the processor to:
execute the image file so as to display a second animation of drawing a second part of the object by using a second hue and a second line width for a second duration period after the first duration period;
receive a second input for stopping execution of the image file for the second duration period; and
display a drawing output comprising the second hue and the second line width.

4. The electronic device of claim 1 , wherein the instructions are configured to cause the processor to:
stop the playback, based on receiving an input for stopping playback of the image file through the display, and display the first section on the display, the first section comprising an image at a time at which the playback is stopped and a picture board arranged above the image and configured to receive a drawing input.

5. The electronic device of claim 4 , wherein the instructions are configured to cause the processor to:
acquire attribute information related to a drawing tool of the image from metadata associated with the image at the time at which the playback is stopped; and
display a drawing output, to which the acquired attribute information is applied, on the picture board,
wherein the attribute information comprises at least one of a type of the drawing tool, a width of a line drawn on the picture board by the tool, a hue of the line, a brightness of the line, and a saturation of the line.

6. The electronic device of claim 4 , wherein the instructions are configured to cause the processor to:
process the image at the time at which the playback is stopped so as to be visually distinguished from an image displayed on the picture board when the image file is played, and display the image at the time at which the playback is stopped on the picture board.

7. The electronic device of claim 1 , wherein the instructions are configured to cause the processor to display, on the display, a button for stopping playback of the image file in the user interface, a timeline indicating an entire playback section of the image file, and a button for selecting whether or not to expose the image file, and display, based on stopping of playback of the image file, a playback button, a button for canceling the drawing output, and a button for displaying again the drawing output, on the user interface.

8. The electronic device of claim 7 , wherein the instructions are configured to cause the processor to divide, based on a designated reference, the entire playback section of the image file into multiple playback sections, and perform playback from a starting time of one of the playback sections, in response to a user input, and wherein
the designated reference comprises at least one of a playback time selected by the user, a playback time at which an attribute of the drawing tool is changed, a time at which drawing of each part of the object starts, and a designated time unit.

9. The electronic device of claim 8 , wherein the instructions are configured to cause the processor to display marks for identifying the playback sections on the timeline.

10. The electronic device of claim 9 , wherein the instructions are configured to cause the processor to display, on the display, a drawing tool corresponding to at least one of the marks.

11. The electronic device of claim 8 , wherein the instructions are configured to cause the processor to repeatedly play at least a part of one of the playback sections a predetermined number of times or until a designated user input is received.

12. The electronic device of claim 1 , wherein the instructions are configured to cause the processor to display, in the first section, movement of a tool for drawing the object while playing the image file.

13. An electronic device comprising:
a touchscreen display;
a processor operatively connected to the display; and
a memory operatively connected to the processor, wherein
the memory comprises instructions that, when executed, cause the processor to:
display, on the display, a user interface comprising a first section configured to receive a drawing input and a second section comprising multiple hues and one or more line widths to be selected for the drawing input;
execute an animation image file to be displayed on the first section, the animation image file comprising an order in which an object is drawn by using at least one hue among the multiple hues and at least one line width among the one or more line widths;
receive an input for stopping executing the image file from the display; and
display a drawing output on the display according to the drawing input, the drawing output comprising a hue and a line width used when the drawing input is received,

wherein the instructions are configured to cause the processor to display a hue used at a time at which the image file is played, among multiple hues displayed in the second section, so as to be distinguished from other hues.

14. A method for operating an electronic device, the method comprising:
displaying, on a touchscreen display, a user interface comprising a first section configured to receive a drawing input and a second section comprising multiple hues and one or more line widths to be selected for the drawing input;
executing an animation image file to be displayed on the first section, the animation image file comprising an order in which an object is drawn by using at least one hue among the multiple hues and at least one line width among the one or more line widths;
receiving an input for stopping executing the image file from the display; and
displaying a drawing output on the display according to the drawing input, the drawing output comprising a hue and a line width used when the drawing input is received,
wherein the method further comprises displaying, on the second sec
