BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal, and more particularly, to sender indication information included in a message and transmitted when the message is transmitted.

In general, a message service method including a short message service (SMS), an enhanced messaging service (EMS), a multimedia messaging service (MMS), and the like is displayed on the caller's phone number in place of information on the caller. However, with the development of mobile terminal technology, it is possible to transmit data such as video or image, not just a text message, and also equipped with a camera in the mobile terminal, so that users simply display the user's phone number. Instead of displaying information, they demanded ways to express themselves more personally.

One of the caller display methods that appeared in response to the request of the users was a camera provided in the mobile communication terminal, and the users stored the images themselves and included the stored images in the message transmitted together with the caller's telephone number. In this caller display method, when a user transmits a message, the image and telephone number stored by the user are transmitted together with the message written by the user, so that the person receiving the message can easily know who sent the message. Therefore, it is true that this method meets the needs of users to some extent.

However, such a caller display method merely includes a face image of the user in the caller information, and thus has a disadvantage in that it is insufficient to express a user's personality. In other words, users who don't want to include their actual photos, users who want to emphasize certain parts of their saved face images, or use humorous techniques such as animation instead of their own face images. For users who want to send their own Caricatures, this caller ID alone could not meet that need. Caricature refers to a picture or sentence that humorously expresses the aspects of an event or human form, and expresses the characteristic part of the face of a particular person in an exaggerated way. I'm talking about images.

Therefore, for users who want to create their own caricatures instead of their actual face images and use them as caller information, these days, users can make their own caricatures or receive face images from their mobile communication terminals. Service companies that provide services that can be changed to the desired form have emerged.

However, in order to receive the service for generating the caricature through such service providers, the user accesses the server of the service provider through a mobile communication terminal, transmits a face image, changes the desired image, and then changes the changed face image again. You must go through the procedure to save. Accordingly, there is a problem in that the user has to pay ancillary expenses such as data access fee and service fee to the circuit operator and service provider. In addition, this method has a problem that the user's personal information may be violated because the user transmits his or her real face image.

Therefore, an object of the present invention is to reduce the cost of incidental consumption of the caricature, such as data access fee and service usage fee, to prevent the possibility that the user's personal information may be infringed, and to display the personality of the user to the user It is an object of the present invention to provide a device and method for producing a caricature or sketch image of a user.

The apparatus of the present invention for achieving the above object is a memory unit having a caricature DB (Database) is stored for each part of the face caricature (Caricatura) image for each part of the face, and the face according to the user's selection A caricature image processing unit for recognizing feature points of each part of an image, retrieving partly caricature images according to the feature points from the caricature DB, and generating a face caricature image by combining the retrieved part caricature images; And a controller configured to output the face image to the caricature image processor, to generate the face caricature image by controlling the caricature image processor, and to set the generated face caricature image as the caller display information according to the user's selection. do.

The method may further include: an image loading step of loading a face image selected by a user, a generation check step of checking whether to generate a caricature image to the user, and according to the check result, the caricature based on the face image is selected. An image generation step of generating an image, and a caller indication information setting step of setting the caricature image as caller indication information according to the user's selection.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

First of all, in order to help a complete understanding of the present invention, the basic principles of the present invention will be described. A mobile communication terminal according to an embodiment of the present invention includes a caricature image processing unit capable of generating a caricature image. When the user selects a specific face image, the controller of the mobile communication terminal according to an embodiment of the present invention loads the face image selected by the user, inputs the loaded face image to the caricature image processing unit, and performs the caricature image processing unit. The control enables the caricature image or the sketch image to be generated based on the loaded face image according to the user's key input. In this case, the specific face image selected by the user generally refers to a face image including a face portion of the user capable of generating a caricature image of the user. In the following description, it is assumed that a face image refers to a face image including a face part of a user as described above. In addition, the controller of the mobile communication terminal according to an embodiment of the present invention may set the caricature image or the sketch image generated by the caricature image processing unit as caller display information. The caricature image and the sketch image may be included in the message and transmitted together with the reply number according to the user's selection.

1 is a block diagram of a mobile communication terminal according to an exemplary embodiment of the present invention. Referring to FIG. 1, a mobile communication terminal according to an embodiment of the present invention includes a memory unit 102, a key input unit 104, a display unit 106, a baseband processor 108, and a coder-coder (CODEC). The camera unit 116 and the caricature image processing unit 118 are connected to the control unit 100. Here, the controller 100 processes voice signals and data according to protocols for telephone calls, data communications, and wireless Internet access, and controls each part of the mobile communication terminal. Then, the user's key input is received from the key input unit 104 to control the display unit 106 accordingly to generate and provide image information according to the user's key input.

If the user selects to generate one of the face images stored in the memory unit 102 as a caricature image, the controller 100 uses the selected face image to determine whether the user generates a sketch image. Check to select. If the user selects to process the face image by the caricature image, the face image is recognized by the feature part for each part, and according to the feature point for each part of the face image through the caricature DB (Data Base) stored in the memory unit. Select a partial caricature image. The caricature image is generated from the face image selected by the user by combining the selected caricature images for each part. However, if the user selects to process the face image by sketch image, the contour of the face image is extracted, and a sketch image is generated from the face image based on the extracted contour with the sketch material according to the user's selection. Do it.

The memory unit 102 connected to the controller 100 includes a read only memory (ROM), a flash memory, a random access memory (RAM), and the like. The ROM stores a program for processing and controlling the controller 100 and various reference data. The RAM provides a working memory of the controller 100, and the flash memory provides an area for storing various updatable data for storage. In addition, the memory unit 102 of the mobile communication terminal according to an embodiment of the present invention includes each part of the face image, that is, a facial outline, a head shape, eyes and eyebrows, a nose and a mustache, lips and a chin, a forehead, Caricature images of the ball and the like are stored in each part. Hereinafter, an area of the memory unit 102 in which such part-specific caricature images are stored will be referred to as a caricature DB (Database) 120. Table 1 below shows examples of caricature images corresponding to the lips of the data list stored in the caricature DB 120.

index Image data Aspect ratio Aspect ratio One lip1 1/7 1/10 2 lip2 1/6 1/15 3 lip3 1/5 1/10 4 lip4 1/5 1/15 ... ... ... ...

Referring to Table 1, it can be seen that the aspect ratio and the aspect ratio are set. This is a condition for searching for a caricature image for each part corresponding to a specific part of the face image selected by the user in the mobile communication terminal according to an embodiment of the present invention. will be. Here, the aspect ratio and the aspect ratio refer to the ratio of the length of the inside of the facial contour recognized from the face image selected by the user and the length of the corresponding region. For example, the aspect ratio of 1/7 refers to a case in which the horizontal length of the lip portion extracted from the face image selected by the user is 1/7 of the inner horizontal length extracted from the selected face image. However, in general, the caricature highlights the characteristic part of the actual image, and thus the caricature image for each part stored in the caricature DB 120 also emphasizes the characteristic part. That is, in the example of Table 1, if the aspect ratio is 1/5 and the aspect ratio is 1/10, the corresponding caricature image lip3 generates a caricature image representing the lips larger than the above ratio.

In addition, the caricature image processing unit 118 removes noise through the simplification process of the input face image under the control of the control unit 100 as described above, and the caricature for each part of the caricature DB retrieved from the control unit 100. The combined caricature image is generated by combining the respective parts, or a sketch image is generated based on the contour of the face image. When generating a caricature image, the caricature image processing unit 118 recognizes feature points for each part of the user's face from the face image from which the noise is removed through a simplification process, and according to the recognized feature points, the caricatures for each part stored in the caricature DB Search for the most suitable caricature image among the images.

There may be several criteria for such a feature point. For example, it may be based on the ratio of the width inside the face outline recognized from the face image to the inside width of the outline of the specific face portion, or the length inside the face outline and the length inside the outline of the specific face portion. The ratio may be based on. In addition, the size or shape of the inside of the contour of the specific face portion, or the distance between the specific face portion may of course be a reference. Of course, these reference points may also be different for each face part. For example, the caricature image processor 118 recognizes the contour of the user's face from the face image selected by the user, and searches for the caricature image of the contour portion most similar to the contour of the user's face among the caricature images of the parts corresponding to the facial contour. . In this case, the size or shape inside the outline of a specific face part is used as a reference for recognizing the feature point. In this manner, the caricature image processing unit 118 recognizes a feature point for each face part, and combines a caricature image for each part retrieved through the recognized feature point under the control of the controller 100 to form one completed face caricature image. Create A process of generating such a caricature image will be described in detail with reference to FIG. 3.

If the sketch image is generated, the caricature image processing unit 118 generates a sketch image by performing a graphic process on the face image from which the noise is removed through a simplification process. In the mobile communication terminal according to an embodiment of the present invention, the face image according to the user's selection is filtered using a filter such as a high frequency filter to extract the contour of the high frequency component from the currently selected face image, and the sketch effect according to the filtered result. Create a sketch image by applying to the contour. A process of generating such a sketch image will be described in detail with reference to FIG. 4.

The key input unit 104 includes various keys including numeric keys as described above, and provides the controller 100 with a key input input from a user. The RF unit 110 serves to transmit and receive an RF signal with the base station. And converts the received signal into an IF (Intermediate Frequency) signal, outputs it to the baseband processor 108 connected to the controller 100, and converts the IF signal input from the baseband processor 108 into an RF signal. Send. The baseband processor 108 is a baseband analog ASIC (BBA) that provides an interface between the controller 100 and the RF unit 110. The baseband processor 108 converts a baseband digital signal applied from the controller 100 into an analog IF signal. The signal is converted and applied to the RF unit 110, and the analog IF signal applied from the RF unit 110 is converted into a digital signal of the baseband and applied to the control unit 100. The codec 112 connected to the controller 100 is connected to the microphone and the speaker through the amplifier 114, and encodes the voice signal input from the microphone to PCM (Pulse Code Modulation) encoding to control the voice data. ) And the voice data input from the controller 100 are PCM decoded and output to the speaker through the amplifier 114. The amplifier 114 amplifies the voice signal input from the microphone or the voice signal output from the speaker, and adjusts the volume of the speaker and the gain of the microphone according to the control of the controller 100. The camera unit 116 stores an input image as an image according to a user's selection. Here, the face image stored through the camera unit 116 may be generated as a caricature image or a sketch image by the user.

2 is a diagram illustrating a process of an operation in which a caricature or a sketch image is generated based on an image selected by a user in a mobile communication terminal according to an embodiment of the present invention and set as caller display information. Referring to FIG. 2, when the user selects a specific face image in the mobile communication terminal according to an embodiment of the present invention, the controller 100 may determine whether to use the specific face image as caller display information although not shown. Is displayed. If the user selects a specific face image to use as caller display information, the control unit 100 proceeds to step 300 and loads the face image selected by the user.

In step 202, the controller 100 determines whether the user generates a new image based on the currently selected face image and sets it as caller display information or sets the currently selected face image as the caller display information. If the user does not want to create a new image, the controller 100 proceeds to step 214 and checks whether to set the currently selected face image as caller indication information. If the user wants to set the sender display information in step 214, the control unit 100 proceeds to step 216 to set the face image selected by the user as the caller display information, and when the user transmits a message according to the user's selection, The selected face image along with the number is transmitted to the caller indication information.

However, if the user selects generation of a new image based on the face image currently selected in step 202, the control unit 100 proceeds to step 204 to generate a caricature image or a sketch image. Make a choice. If the user selects the caricature image generation in step 204, the control unit 100 proceeds to step 206 and controls the caricature image processing unit 118 to generate the caricature image through the caricature image generation process. However, if the user selects the creation of the sketch image in step 204, the controller 100 proceeds to step 208 and controls the Gariature image processing unit 118 to generate the sketch image through the sketch image generation process. When the caricature image or the sketch image is generated from the caricature image processing unit 118, the controller 100 proceeds to step 210 and checks whether the caricature image or the sketch image is currently stored to the user. If the user does not want to save the currently generated image, the process returns to step 202 to check whether or not to generate a new image based on the currently selected face image.

However, if the user selects to store the image generated in step 206 or 208 in step 210, the controller 100 proceeds to step 212 and stores the image currently generated in the memory unit 102. Save to the area. The controller 100 proceeds to step 214 and checks whether to set the currently generated image as the caller display information to the user. If the user wants to set the currently generated image as the sender display information, the control unit 100 proceeds to step 216 to set the currently generated image as the sender display information and the sender when the user transmits the message according to the user's selection. The generated image along with the number is sent to the sender indication information. However, if the user does not want to set the currently generated image as the caller display information in step 214, the control unit 100 generates a caricature or sketch image based on the face image according to the user's selection shown in FIG. 2. The operation set to the display information ends. However, since the image currently generated in step 212 is stored, it can be set by the user as caller display information as much as possible. Therefore, in the mobile communication terminal according to an embodiment of the present invention, not only the face image stored by the user through the camera of the mobile communication terminal, but also the caricature image that caricatures the face image or the sketch image that sketches the face image. The caller indication information may be set according to a user's selection.

3 is a diagram illustrating a process of generating a caricature image by caricature a face image according to a user's selection as shown in step 206 of FIG. 2. Referring to FIG. 3, when the face image selected by the user is input in FIG. 2 and a caricature image generation is selected by the user, the caricature image processing unit 118 proceeds to step 300 under the control of the controller 100. By simplifying the face image currently input to remove the noise (Noise). Examples of such a simplification process include removing the contrast included in the face image, or removing the background image outside the face outline determined through the contour extraction.

When the simplification process is completed in step 300, the controller 100 proceeds to step 302 to recognize the simplified face image for each part. That is, the facial contour of the face image is recognized through the extracted contour, and the shape of the user's head is recognized through a method such as high frequency filtering or a predetermined classification by location. Here, the high frequency filtering is to filter only a high frequency part of the face image, that is, a part in which the density of color is expressed, and may be used to extract the shape of the head or the face. When the contour of each face image such as ear, eye, eyebrow, mouth, nose, mustache, and beard is recognized from the currently selected face image by using the high frequency filtering method, preset position information, that is, the position of the eye in the general human face The contour recognized in the corresponding part for each face part is recognized as each part of the corresponding face by using information about the face. Then, the caricature image processing unit 118 proceeds to step 304 under the control of the control unit 100 to extract the feature points for the portions recognized in each step 302. The feature point recognized in step 304 is used as a reference for retrieving a caricature image from the caricature DB 120.

That is, for example, as a reference for retrieving a caricature image corresponding to a part recognized as the user's lips, the inside of the part recognized as the horizontal length and the face outline of the part recognized as the lip as shown in the example shown in Table 1 The ratio of the width (aspect ratio), and the ratio of the length of the part recognized as the lip portion and the height of the inside (the aspect ratio) inside the part recognized as the face contour may be used. In this case, if the aspect ratio of the lip portion and the inside of the face contour is about 1: 5 and the aspect ratio is about 1:15, the caricature image processing unit 118 is a feature point for the lip portion of the face image. And aspect ratio 1:15. The caricature image processing unit 118 proceeds to step 306 to search for the caricature DB for each part according to the aspect ratio and the aspect ratio in the caricature DB 120. When the search for the part of the caricature image for each part of the face image is completed, the caricature image processing unit 118 proceeds to step 308 under the control of the controller 100, and combines the part of the caricature images found in step 306 to the combination. A caricature image is generated based on a face image according to a user's selection.

Then, the control unit 100 receives the caricature image generated from the caricature image processing unit 118 and proceeds to step 210 of FIG. 2 to check whether or not to store the currently generated caricature image to the user. If the user stores the currently generated caricature image and sets it as the caller indication information, the controller 100 allows the caricature image to be included as the caller indication information according to the user's selection. In FIG. 5, an example of a screen displaying a message in which such a caricature image is included as caller indication information is shown.

In addition, the process of combining the caricature images in step 308 may include the inclination of each part of the face recognized in the original face image. For example, when the parts of the recognized face image recognized by the left eye and the right eye are not on the horizontal line but have some degree of inclination, the caricature image processing unit 118 checks the inclination of both recognized parts. The checked slope corresponding to the caricature image corresponding to the eye of the caricature images found in step 306 is reflected in the caricature image combined in step 308. Therefore, in the present invention, the caricature image is not generated by combining the preset caricature images according to the user's selection, but the caricature image is generated according to the feature points of the face image selected by the user. A caricature image close to may be generated.

4 is a diagram illustrating a process of generating a sketch image by sketching a face image according to a user's selection as shown in step 206 of FIG. 2. Referring to FIG. 4, when the face image selected by the user is input in FIG. 2 and a sketch image generation is selected by the user, the caricature image processing unit 118 proceeds to step 400 under the control of the controller 100. By simplifying the face image currently input to remove the noise (Noise). In this case, the simplification process of step 400 is to remove and simplify the noise component to easily sketch the face image, which is different from the simplification process of step 300 of FIG. 3. For example, if the simplification process in step 300 is to remove the background image and the contrast component, the simplification process in step 400 maintains the background image and the contrast component, and black-and-whites the color of the face image. May be for simplicity.

The caricature image processing unit 118 proceeds to step 402 and extracts the contour of the face image, the shape of the user's head, the eyes and the contours of each part through a filtering method such as high frequency filtering. When the contour extraction of each part is completed in step 402, the caricature image processing unit 118 notifies the controller 100 of this. The controller 100 proceeds to step 404 and displays a menu for the material to be sketched on the contour line extracted in step 402 on the display unit 106. The sketch material may be a pen first, and there may be various things such as charcoal and pencil. When the user selects any one of the sketch materials displayed in step 404, the control unit 100 proceeds to step 406 to carry out a sketch process on the contour extracted in step 402 with the sketch material according to the user's selection. The image processor 118 is controlled. Then, the caricature image processing unit 118 proceeds to step 406 and starts sketching on the extracted contour with the material selected in step 404. When the sketch processing is completed, the caricature image processing unit 118 proceeds to step 408 to generate a sketch image. Then, the control unit 100 receives the sketch image generated from the caricature image processing unit 118 and proceeds to step 210 of FIG. 2 to check whether or not to save the currently generated sketch image to the user. If the user stores the currently generated sketch image and sets it as caller display information, the controller 100 allows the sketch image to be included as caller display information according to a user's selection. In FIG. 5, an example of a screen displaying a message in which such a sketch image is included as caller indication information is shown. Therefore, in the present invention, not only the caricature image, but also allows the user to create a sketch image, such as sketching a face image with a sketch material according to a user's selection, and save and use it as caller display information.

FIG. 5 is a diagram illustrating an example of a screen displaying a message including a caricature image and a sketch image as caller display information of a message according to an embodiment of the present invention as described above. 5A illustrates an example of a message in which a sketch image is included as caller display information, and FIG. 5B is an example of a message in which a caricature image is included as caller display information. First, referring to FIG. 5 (a), it can be seen that the face image is included as the caller display information in addition to the reply number, and the face image is not a simple face image, but a face image like a sketched with a pen. . Referring to FIG. 5B, it can be seen that the face image is included as the caller indication information in addition to the reply number, and the face image is not a simple face image but a caricature image. Of course, the sketch image or the caricature image may allow the user to transmit the original face image from the mobile communication terminal to a personal computer (PC), and the user may generate a sketch image or a caricature through a specific software of the PC. However, in the present invention, the mobile communication terminal itself can generate such a sketch image or a caricature image according to a user's selection without the server of the additional equipment or service company such as the PC, and set it as caller display information. To help.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. In particular, the embodiment of the present invention recognizes the face image selected by the user for each part, retrieves a caricature image for each part suitable for each recognized part from the caricature DB to generate a caricature image most similar to the face image selected by the user. heard. However, in this embodiment of the present invention, the user can directly create a caricature image desired by the user by directly selecting the caricature image for each part using the caricature DB without the face image selected by the user. Also, even if a caricature based on the face image you have selected has already been created, if you want to replace a caricature image of one part with another caricature image of that part while saving the caricature, you can change it as well. to be. That is, if the caricature image generated according to the face image selected by the user includes the caricature image of the eye part without the double eyelid, the user selects the caricature image of the eye part without the double eyelid, Of course, it can also be replaced with a caricature image of the eyelids with double eyelids. Therefore, the scope of the invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

The present invention includes a caricature image processing unit for generating a caricature image, inputs a face image selected by a user to the caricature image processing unit, and based on the face image according to a user's key input, a caricature image or a sketch image To be generated.
