FIGS. 6 to 9 are illustrations for explaining a process of enlarging and displaying a face of interest by voice and gesture recognition according to an embodiment of the present invention.

6 is an exemplary diagram illustrating a one-to-many video call connection according to an embodiment of the present invention.

Referring to FIG. 6, it is assumed in the embodiment of the present invention that a daughter as a sender requests a one-to-many video call connection with a plurality of recipients, that is, a mother 600, a father 610, and a son 620 through a calling apparatus. The control unit 100 of the receiving apparatus 10 recognizes the face image from the image photographed by the camera unit 110 and associates the recognized face image with the user information corresponding to the face to store it in the storage unit 170 do. At this time, the control unit 100 can receive user information about the recognized face from the receiver. Also, when the user information and the face image are stored corresponding to each other in advance such as a phone book, the control unit 100 may compare the previously stored face image with the recognized face, and store the corresponding face in correspondence with the recognized face according to the match.

FIG. 7 is an exemplary view for explaining a process of automatically enlarging and displaying a target of interest related to a keyword extracted from voice data of a caller according to an embodiment of the present invention. Referring to FIG.

7 (a), when the voice data of the caller is received from the calling apparatus 20, the control unit 100 performs speech recognition on the received voice data to extract a keyword corresponding to a plurality of recipients.

For example, the control unit 100 recognizes each word such as " Mom, " ", " It is a long time, " And compares the recognized words with previously stored user information to extract words related to the recipient. If there is stored user information corresponding to " mom ", the control unit 100 can extract " mom "

The control unit 100 detects a matching face among the stored face image and the recognized face in the input image corresponding to the user information related to the " mother ", enlarges the detected face, . ≪ / RTI > At this time, the control unit 100 can display the enlarged image of the mother's face on the preview screen 700 having the predetermined size. Then, the control unit 100 transmits the enlarged image of the face of the mother to the sending apparatus 20 through the communication unit 150.

Accordingly, the calling apparatus displays the enlarged image of the mother's face on the screen 21 as shown in FIG. 7B so that the daughter 630 as a sender can automatically enlarge and display a face of interest of interest do.

8 is an exemplary diagram for explaining a process of automatically enlarging and displaying an object of interest related to response voice data for voice data of a caller according to an embodiment of the present invention.

Referring to FIG. 8, the control unit 100 determines whether or not response voice data is received in response to voice data received from a source apparatus, and confirms the destination of the response voice data when the response voice data is received.

For example, when the voice data 710 of " Mom, me, me? Long time? &Quot; is received from the sending apparatus 20 as shown in Fig. 8 (a) It is determined whether or not it is received. If the response voice data 720 such as " uh-my daughter ~ " is received, the control unit 100 confirms the destination of the response voice data. For example, the control unit 100 detects the voice direction of the received response voice data, and confirms the object located in the detected voice direction.

The controller 100 detects the face of the mother from the image input through the camera unit 110 and enlarges the detected face to display the face enlarged image on the display unit 160. [ And then transmits the enlarged image of the mother's face to the calling party 20 through the communication unit 150. [

Also, the control unit 100 may control the voice recognition unit 130 to recognize a plurality of words from the voice data received from the calling apparatus 20, and may extract words matching the user information from the recognized words. The control unit 100 determines whether or not the response voice data is received in response to the voice data received from the sending apparatus 20, and confirms the transmission destination of the response voice data when the response voice data is received. The controller 100 performs face recognition on the identified object to search for a face image matching the recognized face, and determines whether the user information corresponding to the detected face image matches the extracted word. If the user information corresponding to the searched face image coincides with the extracted word, the control unit 100 detects the mother's face from the image input from the camera unit 110, enlarges the detected face, Is displayed on the display unit 160, and then the enlarged image of the face is transmitted to the calling apparatus through the communication unit 150. [

For example, when a word such as a mother is detected from the voice data such as " Mom, me or me? &Quot; received from the calling apparatus 20 and it is determined that the subject who transmitted the response voice data is a mother, The controller 100 detects the mother face from the input image and enlarges the detected mother face to deliver the enlarged image of the mother's face to the transmitting device 20 so that the interest The face of the object can be automatically enlarged and displayed on the screen 21.

9 is an exemplary diagram for explaining a process of automatically enlarging and displaying an object of interest through gesture recognition according to an embodiment of the present invention.

Referring to FIG. 9, the control unit 100 determines whether or not response voice data is received in response to voice data received from the calling apparatus, and confirms the transmission destination of the response voice data when the response voice data is received. The control unit 100 controls the gesture recognition unit 140 to recognize the gesture of the identified object to determine whether the gesture of the identified object is recognized.

9 (a), when the mother recognizes a gesture in which the detection and the stop are in the form of V (v), the control unit 100 detects the mother face from the input image, The face of the mother 630 is enlarged and the enlarged image of the mother is transmitted to the originating device 20 so that the face of the interested person interested in the caller 630 is automatically enlarged and displayed on the screen 21 as shown in FIG. .

In the embodiment of the present invention, one recipient is determined to be a target of interest when a one-to-many video call is concatenated. However, one or more recipients may be determined as a target of interest. For example, when voice data of " Mom and Dad Hello " is received from the calling apparatus, the control unit 100 extracts "Mom" and "Dad" from the voice data by keyword and detects user information corresponding to the mother and father Detects the objects corresponding to the stored face image corresponding to the detected user information, enlarges the detected objects, displays the enlarged image on the screen, and transmits the enlarged image to the originating device. Thus, the sending apparatus can output the enlarged image of the face of the mother and father on the screen.

The face recognition unit 120, the voice recognition unit 130, and the gesture recognition unit 140 are separately formed in the embodiment of the present invention. However, the face recognition unit 120, The control unit 100 may perform operations of the face recognition unit 120, the voice recognition unit 130, and the gesture recognition unit 140 without separately providing the gesture recognition unit 130 and the gesture recognition unit 140. [

As described above, according to the present invention, when a user is interested in a conversation between a caller and a recipient in a one-to-many video call, a specific gesture recognition is performed, and the interested object is enlarged and displayed, do.
