Abstract: Provided is a method of drawing and replaying a picture guestbook using a vector stroke, the method including: displaying an original vector image; determining a selected vector stroke among all vector strokes of the original vector image according to a user input, and detecting an operation step of the selected vector stroke; receiving a picture guestbook drawn on the original vector image, and obtaining vector stroke information of the picture guestbook based on the detected operation step; and drawing and replaying the picture guestbook based on the vector stroke information of the original vector image.

Abstract: Discloses is a method for photographing a dynamic picture and a dynamic video, the method including: (a) selecting a photographing target; (b) setting a total photographing time and a camera action operation time; (c) selecting at least one camera action operation; and (d) photographing a dynamic movement by applying the camera action operation for the set time. Accordingly, various dynamic movements are photographed by selecting the photographing target, setting a time during which a camera action is operated in the total photographing time, and selecting the camera action for the set time.

Abstract: A method for replaying a vector image. The method includes: (a) extracting replay information and work environment information of each of the vector lines from an original vector image; (b) receiving a selection of regions of specific vector lines from a user; (c) changing and updating replay settings of the vector lines selected in step (b); (d) replaying the vector image selected by the user; and (e) storing the updated information of the vector image or ending the method for replaying the vector image. Therefore, it is possible to sequentially store every step of drawing work and even a work environment, in addition to vector line information, and replay the stored vector image, as if a scene in which an actual artist was drawing a picture were recorded, while breaking away from the conventional batch replay method of a vector image.

Abstract: A method of converting and replaying styles of vector images. The method includes: generating a first original completed image from a vector original image; generating a second style conversion completed image whose styles are converted to styles of another artist's famous art work for style conversion; extracting line information of the second style conversion completed image matching coordinate values of vector lines selected by a user from the vector original image with reference to the second style conversion completed image; changing information of the selected vector lines and displaying the information to the user; and preparing a configuration including a step of generating a new vector image whose style is converted to show a style conversion process in real time, as if a real artist were painting, thereby being able to provide many effects to the user to appreciate and learn to draw pictures.

Abstract: The present disclosure relates to a turn-based pictorial chat application and a method for a pictorial chatting installed in a user terminal, which comprises storing a process of completing a picture in a chronological order from a start of drawing the picture when a first user draws the picture through a picture input window displayed on a display part of a user terminal, wherein a plurality of stage data capable of distinguishing positions are inserted according to a degree of completion of the picture; transmitting the stored picture to a user terminal of a second user as a chat participant; displaying the transmitted picture on a display of the user terminal of the second user; and displaying the picture drawn on the user terminal in chronological order according to the selection of the second user.

Abstract: Disclosed are a device and method for changing the color of text displayed on a display device, which enable the color of the text, a picture or the like displayed on the display device to be easily changed through a simple input of a user. The device for changing the color of text displayed on a display device comprises: receiving and setting the color of text to be changed on the display device; receiving a user input for changing the color; recognizing a position at which the input for changing the color of the text is inputted and determining a color change region according to the position; and changing the color of the text in the color change region to the color set in the setting the color of text.

Abstract: A display brightness control method includes the steps of comparing a display-setting value, which is input by user operation, with a setting value, which is set in advance to a display, if a changed setting value is present, reflecting the changed setting value to the display, determining whether or not the display-setting value is present, if the display-setting value is present, reflecting the changed display-setting value to the display, and after the changed display-setting value is reflected, standing by until a subsequent display-setting value is input. In addition, the screen output areas of the display divided into the used area and the unused area, so that the used area remains original and the unused area is controlled to have the minimized level of brightness or be powered off. It is possible to prevent the visibility from being lowered by the display and protect the vision of the user.
