Description

Apparatus and method for sending and receiving handwritten animation messages {APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING HANDWRITING ANIMATION MESSAGE}

The present invention relates to text message transmission, and more particularly, to an apparatus and method for transmitting and receiving a handwritten animation message service.

As various technologies such as wired or wireless communication technology, multimedia technology, hardware manufacturing technology such as a central processing unit and memory, and power charging technology are developed, the functions of the mobile terminal are further strengthened. For example, although the conventional mobile terminal delivers a content to be communicated to the other party by using a voice call, when a text message is impossible to transmit or receive after a text message becomes available, a simple text content is transmitted. By using a short message service (SMS) that includes, it is possible to simply deliver the contents to be communicated to the other party.

Such a short message service has been developed from SMS to a long message service (LMS) including a text of long text, and to a multimedia message service (MMS) including multimedia files such as images and videos. Advances have made it possible to offer users more diverse benefits. In particular, unlike SMS or LMS, which transmits only text contents, in case of MMS, which transmits multimedia files, user demand is gradually increasing due to the extensibility of the expression. Referring to the method of transmitting the desired content using the MMS as follows.

1 is an exemplary view showing a mobile terminal for performing information transmission using a conventional MMS.

Referring to FIG. 1, an MMS may be created by inputting a desired character and attaching an image to be attached. In the MMS input method shown in FIG. 1, the keypad 105 is used for input, but in the case of a mobile terminal supporting a touch screen, a desired character may be directly input on the screen using an input tool such as a finger or a stylus pen. It may be. The image attachment is attached by calling up an image stored separately in the memory by using the file attachment field 103 located at the bottom of the text input window 101.

However, currently used MMS performs transmission including only pre-stored images or videos. If you want to send the handwritten contents directly from the sending mobile terminal using MMS, you need to use a separate program to change the handwritten contents into an image or video file, save them, and then send them. That is, when the receiving mobile terminal receives an image included in the MMS, only one still image is shown, and the writing process of the transmitting mobile terminal user cannot be reproduced sequentially. 'S handwriting or emotion cannot be conveyed as it is, and the dynamics disappear.

In addition, in the case of transmitting a plurality of images or videos, there is a problem in that the receiving user must download and confirm a plurality of attached images or videos in order to check the order of the images or videos created by the transmitting user.

The present invention proposes an apparatus and method for synchronizing one or more handwritten animation messages and a specific background image into a group and transmitting them to a receiving mobile terminal in order to effectively deliver the handwritten animation message and a specific background image.

In addition, the time information and coordinate information of the points constituting the handwriting animation message are stored in a specific area of the final still image in which the handwriting animation message is completed on the specific background image, and transmitted to the receiving mobile terminal to transmit the handwriting area from the final still image. The present invention proposes an apparatus and method for reproducing a specific background image which has been removed to reproduce a handwritten animation message on the restored specific background image.

According to an aspect of the present invention, an apparatus for transmitting a handwritten animation message, comprising: an input unit for receiving a handwritten animation message including coordinate information and time information of points input on a background image from a user of a transmitting mobile terminal; And a control unit configured to control to merge or synchronize a background image and the handwritten animation message, and a transmitter to transmit the merged or synchronized background image and the handwritten animation message to a receiving side mobile terminal.

According to another aspect of the present invention, in the apparatus for receiving a handwritten animation message, the handwritten animation message including coordinate information and time information of the background image and the points input on the background image from the transmitting mobile terminal is merged or synchronized; A receiving unit, a control unit controlling to play the handwritten animation message on the background image using the merged or synchronized background image and the handwritten animation message, and sequentially playing the handwritten animation message under the control of the controller It characterized in that it comprises an output unit for outputting.

According to the present invention, by synchronizing and transmitting one or more handwritten animation messages and a background image into one group, the user of the sending mobile terminal can effectively reproduce the contents when the user of the transmitting mobile terminal has more than two pages. There is.

In addition, by generating the final still image and storing the handwritten stroke information of the handwritten content in a specific area of the final still image, the mobile terminal separates the original background image from the final still image without the original background image at the receiving mobile terminal and then sends the handwritten animation message. There is an effect that can play.

Also, the time information and the position information of the points constituting the handwriting animation message are stored in a specific area of the final still image in which the handwriting animation message is completed on the specific background image, and transmitted to the receiving mobile terminal to transmit the handwriting area from the final still image. By restoring a specific background image from which the handwriting is removed, there is an effect of confirming the background image from which the handwriting area is removed even in a mobile terminal which cannot reproduce the handwriting animation message.

Referring to FIG. 2, the input unit 201 serves to receive one or more handwritten animation messages from a user. One handwritten animation message is composed of a plurality of points, and each generated point includes unique coordinate information and time information. The coordinate data and the time information of each point are defined as handwritten data. The synchronization unit 203 synchronizes the background data and the writing data in which the coordinate information and time information of each point are data. Synchronization may be performed by using a message identifier, and synchronization may be performed by using various information included in the message identifier. Also, depending on the user setting, the synchronization process may be performed only when necessary. The output unit 205 sequentially plays one or more handwritten animation messages on the background image.

The handwriting content merging and separating unit 211 generates a final still image by merging the writing content written on the specific background image and the specific background image, and separates the specific background image and the writing content from the final still image. The final still image refers to a still image in which the handwritten contents which are completed on a specific background image are displayed in an overlapping form, and is encoded in a format such as JPG or GIF later. The specific region of the final still image may include at least one of stroke information of handwritten content or pixel information of a specific background image. In the drawing, the handwritten content merging and separating unit 211 is shown as one component, but the handwritten content merging unit and the handwritten content separating unit may be divided into respective components and defined.

The memory unit 207 stores a specific background image, one or more handwritten data, and one or more final still images, and stores a map application linked with GPS.

The GPS receiver 213 serves to receive the position information of the transmitting mobile terminal or the position information desired by the transmitting mobile terminal through the GPS. The received location information can be output to the screen in association with the pre-stored map application. It also serves as a navigation device upon user request.

The control unit 209 sends one or more handwriting data input from the input unit 201 and a background image stored in the memory unit 207 to the synchronization unit 203, and sequentially transmits the synchronized background image and the one or more handwriting animation messages. It plays a role to control playback. Also, the stroke information of the handwritten content is stored in the final still image, and the stroke information of the merged handwritten content is extracted from the final still image. The transceiver 215 transmits and receives a handwritten animation message or a background image. The transceiver 215 may also define a transmitter and a receiver separately from each other.

3 is an exemplary diagram illustrating a process of creating a handwritten animation message by sequential time information according to an embodiment of the present invention.

Referring to FIG. 3, each point includes unique coordinate information and time information, and when a single point or a set of points occurs, encoding is performed to generate a code and display it on the edge of the screen in real time. . The reason for displaying the code at the edge of the screen is to minimize the damage of the original image. As shown in the drawing, when the information "take a cup of coffee" is written, different codes are generated according to the coordinate information and time information of each point, and the generated codes are displayed on the screen at the same time as the edges of the screen. Are displayed sequentially.

When the input of the handwritten animation message is artificially terminated, or when the generated codes fill the edges of the screen, a code indicating the end of the handwritten animation message is generated and stored in an arbitrary area of the edge of the screen, and then the final still image is generated. And encode it into an image file of a specific format. Specific image files may include a JPEG format, a GIF format, and the like. In the figure, a sign generated at the edge of the screen in the clockwise direction is input from the upper left of the screen, but this may vary according to a user's setting.

4 is an exemplary diagram illustrating a process of storing coordinate information and time information of points constituting a handwritten animation message according to an embodiment of the present invention. In FIG. 3, the coordinate information and the time information of the generated points are coded and stored at the edge of the screen. In FIG. 4, at least one image file is generated after generating the final still image and encoding the image into an image file having a specific format.

Specific image files may include a JPEG format, a GIF format, and the like. The image file of FIG. 4 basically includes an image start field 401, an image header field 403, an image data field 405, and an image end field 407, and a point sequence data field 409 may be added. have.

Referring to FIG. 4, the image start field 401 and the image end field 407 respectively store data representing the start and end of a specific image format, and the image data field 405 stores the final still image as data. The value is stored. Handwriting data obtained by converting coordinate information and time information of points constituting the handwriting animation message into data is stored in the image header field 403. In addition, the handwriting data may be stored in the point sequence data field 409 generated by generating a point sequence data field 409 after the image end field 407 instead of the image header field 403.

In the scheme of FIG. 3, since the coordinate information and time information of the points on the edge of the screen are coded and stored in the edge of the final still image, there is a limitation that only the area of the writing data can be stored, but in the case of the scheme of FIG. Since a field is generated after encoding the file to store handwriting data, a larger amount of handwriting data can be stored without limiting the storage capacity. Next, a process of playing the handwritten animation message generated in the manner of FIGS. 3 and 4 will be described.

5 is an exemplary diagram illustrating a process of playing a handwritten animation message by sequential time information according to an embodiment of the present invention. Even if the handwritten animation message is generated by another method as shown in FIGS. 3 and 4, the playback process is the same if the mobile terminal supports the handwritten animation message service.

Referring to the playback process when the handwritten animation message is generated by the method of FIG. 3, starting with a code corresponding to the start of the handwritten animation message, decoding is performed in a clockwise direction, and the corresponding handwritten animation message is output in real time. To play on. For example, when a handwritten animation message of "take a coffee" is received, one or more codes encoded according to the coordinate information and time information of each point are decoded, and the points are sequentially reproduced on the screen using the decoded information. . One or more codes displayed on the screen frame of the transmitting mobile terminal are not displayed on the output of the receiving mobile terminal.

Referring to the playback process when the handwritten animation message is generated by the method of FIG. 4, the handwritten animation message corresponding to the specific data in the specific field is analyzed and played back on the screen in real time. For example, when a handwritten animation message of "take a cup of coffee" is received, each point according to the handwritten data obtained by data-coordinate and time information of the respective points included in the image header field 403 or the point sequence data field 409. Play them on the screen sequentially.

Next, when the handwriting data in which the coordinate information and time information of the plurality of points constituting the handwriting animation message are transmitted through the MMS together with the plurality of background images, the mobile terminal user performs synchronization by performing synchronization prior to transmission. A method of sequentially playing a desired handwritten animation message on a desired background will be described with reference to the following embodiments.

6 is a diagram illustrating a message identifier storage according to an embodiment of the present invention. The message identifier is for synchronizing the writing data or the background image into one group. When a plurality of background images and a plurality of writing data are transmitted together, the message identifier is assigned to the same image by assigning the same message identifier to the specific image and the specific writing data. Synchronize.

Referring to FIG. 6, the handwritten animation message may be stored in an arbitrary region of the screen border in the same manner as in FIG. 3, or may be added to a specific field in the same manner as in FIG. 4. You can also adjust the image brightness level or code the message identifier to conceal it in any area before storing it. The message identifier is then dataized along with the coordinate information and time information of the points. In the case of the background image, in order to minimize the damage of the original image, the message identifier is stored in an arbitrary area of the screen border as shown in FIG. 3. The background image can also be concealed by adjusting the brightness level of the border or by coding the message identifier.

7 is a diagram illustrating an internal configuration of a message identifier according to an embodiment of the present invention. The internal structure of the message identifier depends on the handwritten animation message and the background image.

Referring to FIG. 7, a message identifier of a handwritten animation is composed of a message identification number 701, a page number 703, a total number of pages 705, and a background image number 707. The message identification number 701 is used to identify a handwritten animation message or background image having the same message identifier. If the message identification numbers 701 are identical, they are synchronized to the same group. For example, if the message identification number 709 of the background image and the message identification number 701 of the handwriting animation message are the same, they may be synchronized to the same group and the handwriting animation message may be played on the synchronized background image.

The page number 703 denotes the order in which the own number of handwritten animation messages synchronized are reproduced. For example, if three handwritten animation messages are synchronized, a page number 703 may be assigned to each handwritten animation message to determine the playback order.

The total number of pages 705 means the total number of synchronized all handwritten animation messages, and the background image number 707 means the number of the background image to be the wallpaper. If the background image number 707 is blank, it is played without the background image.

The message identifier of the background image is composed of a message identification number 709 and a background image number 711. The message identification number 709 is used to confirm a handwritten animation message having the same message identifier. If the message identification numbers 709 are identical, they are synchronized to the same group. The background image number 711 means a unique number owned by the background image. If there is a handwriting animation message having a background image number equal to its own background image number 711, the handwriting animation message is used as a background image while the handwriting animation message is played.

8 illustrates a comparison between message identifiers according to an embodiment of the present invention. 8 illustrates the message identifiers of the first and second handwritten animation messages and the message identifiers of one background image.

Referring to FIG. 8, it can be seen that the message identification number 801 of the first handwritten animation message, the message identification number 809 of the second handwritten animation message, and the message identification number 817 of the background image are all “63154”. . This means the same group, which is synchronized to one group. The playback order is determined by the page numbers included in the message identifiers of the two handwritten animation messages. Since the page number 803 of the first handwritten animation message is "0" and the page number 811 of the second handwritten animation message is "1", the second handwritten animation message after the first handwritten animation message is played. Means to play. Since the total number of handwritten animation messages is two, the total number of pages 805 and 813 of the first and second handwritten animation messages is recorded as "2".

Further, in both the handwritten animation messages, the background image numbers 807 and 815 are recorded as "0", and the background image number 819 of the background image is also recorded as "0", so that the first and second images are placed on the background image. Play handwritten animation messages sequentially. If the background image numbers 807 and 815 of the first and second handwritten animation messages are blank, they are played without the background image.

9 is an exemplary diagram illustrating a handwritten animation message playback using a message identifier according to an embodiment of the present invention.

Referring to FIG. 9, when the first and second handwritten animation messages and one background image are synchronized to one group, the first and second handwriting are placed on the background image according to the page number and the background image number included in the message identifier. Animation messages can be played sequentially. The playback time may vary depending on the user setting. For example, after the reproduction of the first handwritten animation message may be started, the reproduction of the second handwritten animation message may be started, or the reproduction of the second handwritten animation message may be started while the reproduction of the first handwritten animation message is being performed. It may be.

7, 8, and 9 omitting the process of transmitting coordinate information, time information, and message identifiers of points constituting the handwritten animation message, but the transmitting mobile terminal uses the handwritten animation message having the message identifier as handwriting data. After the data is converted, it is transmitted to the transmitting mobile terminal, and the transmitting mobile terminal can check the synchronized background image using the message identifier included in the handwritten data.

10 is a flowchart illustrating a process of playing a handwritten animation message using a message identifier according to an embodiment of the present invention.

Referring to FIG. 10, in step 1001, a receiving mobile terminal receives an MMS from a transmitting mobile terminal. In step 1003, the receiving mobile terminal determines whether handwritten data exists in the received MMS. If the handwritten animation message does not exist, the process proceeds to step 1005 to output the general image included in the MMS to the screen. If the handwritten data exists, the flow proceeds to step 1007 to extract a message identifier of the handwritten data. The message identifier includes a message identification number, page number, total page number, and background image number.

In step 1009, the receiving mobile terminal determines whether other handwriting data exists in the MMS, and if so, extracts the message identifier of the other handwriting data to determine whether the message identification numbers are the same. If the same message identification number exists, the process proceeds to step 1017 to determine whether a background image having the same message identification number exists. If there is a background image having the same message identification number, the flow proceeds to step 1021 to sequentially play two or more handwritten animation messages on the background image. If there is no background image having the same message identification number, the flow proceeds to step 1019 to sequentially play two or more handwritten animation messages without the background image.

If no other handwritten data exists in the MMS or the same message identification number does not exist in step 1009, the process proceeds to step 1011 to determine whether a background image having the same message identification number exists. If there is a background image having the same message identification number, the flow proceeds to step 1015 to play the handwritten animation message on the background image. If no background image with the same message identification number exists, the flow proceeds to step 1013 to play the handwritten animation message without the background image.

Next, when the final still image including the handwritten stroke information of the handwritten content is sent without performing a synchronization process, the handwritten animation message is separated from the specific background image and the handwritten content to the original specific background image before the handwritten content is written. The following describes the process of sequentially playing.

11 is a flowchart illustrating a process of generating a final still image including handwritten stroke information of handwritten content according to an exemplary embodiment.

Referring to FIG. 11, in operation 1101, the transmitting-side mobile terminal generates a final still image in which the handwritten contents completed on the specific background image are shown to overlap each other. In operation 1103, the transmitting-side mobile terminal stores the writing stroke information of the writing content in a specific area of the final still image. The specific area may vary according to user settings. For example, the handwritten stroke information of the handwritten content may be stored in the header field of the final still image together with the coordinate information and time information of the points constituting the handwritten animation message, or a new field may be generated and stored. In operation 1105, the final still image in which the writing stroke information of the writing content is stored is encoded into an image file having a specific format. An image file of a specific format may be JPG or GIF, and may be encoded into an image file of another format according to a user's setting. In addition, when the handwritten animation message is written in color, the pixel information of the dots is also included and encoded into an image file of a specific format. In operation 1107, the image file encoded in the specific format is transmitted to the receiving terminal.

Although not shown in FIG. 11, the transmitting-side mobile terminal may store the pixel information of the specific background image together with the handwritten stroke information of the handwritten content in a specific region of the final still image to facilitate the extraction of the handwritten content information later.

12 is a flowchart illustrating a process of extracting handwritten stroke information of handwritten content from a final still image according to an exemplary embodiment.

Referring to FIG. 12, in operation 1201, a receiving mobile terminal receives an image file encoded in a specific format from a transmitting mobile terminal. In operation 1203, the receiving mobile terminal decodes a file encoded in a specific format into a final still image. The specific region of the decoded final still image includes handwritten stroke information of the handwritten content in addition to coordinate information and time information of points constituting the handwritten animation message. In step 1205, the receiving-side mobile terminal separates a specific background image and the handwriting content from the final still image by using an inpaint technique, which is a technique of restoring the damaged, faded, or erased portions of the image, before the handwriting is created. Restore the original specific background image. In step 1207, the receiving-side mobile terminal sequentially reproduces the handwritten animation message on the original background image by using the coordinate information and time information of the points constituting the handwritten animation message included in the specific region of the final still image.

Although not shown in FIG. 12, when the pixel information of the specific background image is additionally included in the specific region of the final still image, the pixel information of the specific background image covered by the writing content is extracted to extract the original specific background image before the writing content is written. Can be restored In addition, in the case of the final still image in which the color values of the region of the specific background image overlapping the handwritten content are blended, the original specific background image may be restored using the following equation.

In Equation 1, X1 denotes a color value of an original specific background image, X2 denotes a color value of handwritten content, and Y denotes a color value of a blended area.

Next, when the sending mobile terminal wants to transmit its location to the receiving mobile terminal by using a handwritten animation message, it replaces a specific background image with map information of a map application and sends it to the receiving mobile terminal. The location of the mobile terminal can be transmitted. It will be described in detail with reference to the following examples. In the present invention, it is assumed that the map application stored in the transmitting mobile terminal and the receiving mobile terminal is the same application.

FIG. 13 is a flowchart illustrating a process of creating a handwritten animation message using map information as a background image according to an embodiment of the present invention.

Referring to FIG. 13, in step 1301, the transmitting mobile terminal requests its location information before composing a handwritten animation message. In step 1303, the transmitting-side mobile terminal receives and confirms GPS data corresponding to its location information through the GPS receiver. Thereafter, in step 1305, the map application is executed and the map information corresponding to the current location of the transmitting mobile terminal is output on the user screen in association with the received GPS data. In operation 1307, the user of the transmitting-side mobile terminal creates a handwritten animation message based on the map information output on the user screen. When the writing animation message is completed in step 1309, the final still image is generated, and the location information of the transmitting mobile terminal is stored in a specific area of the final still image. In operation 1311, the final still image is encoded into an image file having a specific format and transmitted to the receiving side mobile terminal.

The receiving mobile terminal may set an accurate destination by referring to the handwritten content of the handwritten animation message played on the map application, and may perform a navigation function by performing a route search from the current location. For example, when the sender mobile terminal searches for a meeting place using a map application and creates and sends a handwritten animation message with a map application centered on the searched meeting place as a background screen, the receiving side receives the received message. The mobile terminal designates a meeting place displayed on the map application as a destination, and can easily move to the destination by performing a route search at the point where the current mobile terminal is located.

In the figure, it is assumed that the transmitting mobile terminal and the receiving mobile terminal use the same map application. However, if the compatibility problem is overcome, the same function may be performed between the mobile terminals using different map applications.

14 is a flowchart illustrating a process of playing a handwritten animation message based on map information according to an embodiment of the present invention.

Referring to FIG. 14, in operation 1401, the receiving side mobile terminal receives an image file encoded in a specific format and decodes the final still image. The location information of the transmitting user is stored in a specific area of the final still image. In step 1403, the stored location information is extracted, and the map application is executed to interwork with the extracted location information. In step 1405, the receiving mobile terminal outputs map information corresponding to the current location of the transmitting mobile terminal on the user screen. In operation 1407, the receiving mobile terminal reproduces the handwritten animation message based on the map information corresponding to the current location of the transmitting mobile terminal.
