[Embodiment 1]
FIG. 1 is a diagram showing a schematic configuration of a mobile terminal according to Embodiment 1 of the present invention. In the present embodiment, a portable terminal equipped with an image generation apparatus that generates image data in which control information for controlling the display form of an original image necessary for reproduction of a morphed image is embedded as digital watermark information will be described. The display form includes a display shape, pattern, and color. The mobile terminal 100 mainly includes an image generation device 10 that generates a new image in which the display form of the original image is changed, an image reproduction unit 20, a scenario information change unit 30, a camera 40 that acquires the original image, a memory 50, A control unit 60, a telephone function unit 70, and a communication unit 80 are provided.

  The image generation apparatus 10 embeds control point information, scenario information, and audio information, which are control information necessary for generating a morphing image, as a digital watermark in still image data (original image), and includes image data and its control information 1 This block generates one file, and includes a control point information generation unit 11, a scenario information generation unit 12, a digital watermark embedding unit 13, and the like. The control point information is position information of control points for generating a morphing image, and the scenario information is information for controlling movement of the control points. The control point information generation unit 11 and the scenario information generation unit 12 generate control information for controlling the display form of the original image. A detailed functional configuration inside the image generation apparatus 10 will be described later.

  The image reproduction unit 20 is a block that separates control information from the image data generated by the image generation apparatus 10 and reproduces a morphed image based on the scenario information, and includes an LCD (liquid crystal display) necessary for image reproduction. A detailed functional configuration inside the image reproduction unit 20 will also be described later.

  The scenario information changing unit 30 is a block that changes the scenario information used by the image reproducing unit 20 for reproducing the morphed image based on various conditions. An example of a condition for changing scenario information will be described later.

  The camera 40 has a function of acquiring an original image, and generates still image data in a predetermined compression format by an operation of the operator of the mobile terminal 100. A series of processing procedures such as imaging from a CCD, analog signal processing, A / D conversion, digital signal processing, and data compression may be performed using a known method. Alternatively, the original image may be acquired by storing still image data generated by shooting in advance in a memory 50 described later and acquiring the image data from the memory 50.

  The memory 50 stores still image data captured by the camera 40, a control program for controlling the operation of each part of the mobile terminal 100, and the like. The control unit 60 includes a CPU and is a block that controls the entire operation of the mobile terminal 100. In particular, the image generation device 10, the image reproduction unit 20, and the scenario information change unit 30 are realized by executing the respective control programs stored in the memory 50 by the control unit 60.

  The telephone function unit 70 is a block that realizes a function as a mobile phone, and controls transmission and reception of telephones and e-mails. The communication unit 80 includes an antenna 81 and realizes a function as a communication unit that is communicably connected to another mobile phone, a mobile terminal, a server, or the like via a wireless telephone network, the Internet, or the like.

  FIG. 2 is a diagram illustrating a functional configuration of the image generation device of the portable terminal according to Embodiment 1 of the present invention. The image generation apparatus 10 includes a variable length decoding (VLD) unit 14 that performs variable length decoding of JPEG image data (original image), a quality extraction unit (IQ) 15 that extracts a Q factor that is an image compression rate, The quality resetting unit 16 for resetting the Q factor to a value based on a desired image quality, the control point information generating unit 11, the scenario information generating unit 12, and the control information such as the generated control point information, scenario information, and sound information are electronically transmitted. A digital watermark embedding unit 13 to be embedded as a watermark, a variable length coding (VLC) unit 17 for performing variable length coding on data after embedding control information, and the like. The quality extracting unit (IQ) 15 and the quality resetting unit 16 adjust the image quality of the original image in which the control information is embedded.

  FIG. 3 is a flowchart showing the procedure of the control information embedding operation of the image generation apparatus of the portable terminal according to Embodiment 1 of the present invention. A face image of the subject is photographed by the camera 40 (step S101), and feature points are detected by a known shape model generation method (step S102). The control point information generation unit 11 generates control points from feature points (step S104) while determining whether all necessary control points have been generated (step S103), and generates shape model data. The captured still image data is encoded (step S105), and the created JPEG image data (step S106) is temporarily stored in the memory 50. Through the above procedure, JPEG image data and shape model data relating to the face image photographed by the camera 40 are generated.

  Next, the created JPEG image data is decoded by the variable length decoding unit 14 (step S107). It is determined whether or not image quality adjustment is performed (step S108). When image quality adjustment is performed, the quality extraction unit 15 extracts the Q factor (step S109), and the quality resetting unit 16 resets the Q factor to optimize. Adjustment to image quality is performed (step S110). If embedding is performed in a state where the quality of the JPEG image data is low, image quality degradation may be conspicuous, and in order to suppress this, the Q factor may be reset so that the image becomes a certain quality or higher.

  Next, audio information to be reproduced simultaneously with the reproduction of the morphing image and scenario information for controlling the movement of the control points necessary for generating the morphing image are acquired. The audio information and the scenario information are respectively generated in advance ( Step S111 and Step S112) are stored in the memory 50. The movement of the subject in morphing is realized by controlling the displacement of the control points, but the scenario information may be created using a known method.

  Next, control information such as control point information, scenario information, and voice information is electronically stored in block units of DCT (discrete cosine transform) coefficients (coefficients of the frequency of the original image) obtained by decoding by the digital watermark embedding unit 13. It is embedded as watermark information (step S113). Here, details of embedding the control information in the DCT coefficient will be described.

  FIG. 4 is a diagram showing an outline of embedding digital watermark information in a DCT coefficient block. In this embodiment, as shown in FIG. 4 (a), the DCT coefficients of the block of 8 × 8 cells are obtained in the decoding by the variable length decoding unit 14, so as shown in FIG. 4 (b). The control point information is embedded by performing a zigzag scan from the upper left in a proper order. Here, as shown in FIG. 4C, 16-bit control point data is embedded in 16 locations on the low frequency component side according to a predetermined rule (in this embodiment, when the embedded data is 0). Is set to increase or decrease the coefficient by 1 so that the DCT coefficient is an even number, and when the embedded data is 1, the DCT coefficient is an odd number). In a similar manner, control point information, scenario information, and audio information are embedded in the DCT coefficient block as digital watermark information.

  As described above, since 16-bit information is embedded on the low frequency component side (low frequency region), the information can be embedded without substantially increasing the amount of information. On the other hand, the amount of information increases when embedding is performed in a cell having a large coefficient on the high-frequency component side and having a coefficient of 0, that is, a cell having no information.

  FIG. 5 is a diagram illustrating a data configuration example of digital watermark information. The electronic watermark information includes an identification number for identifying whether or not the electronic watermark information is embedded, an identification number for identifying a predetermined morphing application, control point information indicating the coordinates (position) of each control point, and movement of the control point It is composed of scenario information indicating the type of operation and start frame, voice information, and the like. For example, in the scenario information shown in the figure, first, the presence / absence of repetition (present = 1, none = 0), and then the start frame number, the number of frames, and the type of operation are arranged. 5 and 6) show a scenario in which the expression “motion” of motion number 6 is performed from the third frame to the fifth frame from the start. The data structure of the digital watermark information, the structure of the scenario information, and the like are not limited to the above structure, and may be arbitrarily determined.

  As shown in the flowchart of FIG. 3, after the digital watermark information is embedded in the DCT coefficient block, the variable length encoding unit 17 encodes the image data (step S114), and the JPEG image in which the digital watermark information is embedded. Data is generated (step S115). Through the above procedure, JPEG image data in which control information and audio information for reproducing a morphed image are embedded as a digital watermark is generated.

  FIG. 6 is a diagram showing a functional configuration of the image playback unit and the scenario information change unit of the mobile terminal according to Embodiment 1 of the present invention, and shows a detailed functional configuration inside the image playback unit 20. The image reproduction unit 20 includes a variable length decoding unit 21 that performs variable length decoding of JPEG image data in which digital watermark information is embedded, a DCT coefficient acquisition unit 22 that extracts DCT coefficients, and controls the original image data from the DCT coefficients. Information separation unit 23 that separates point information, scenario information, and voice information, scenario information acquired by separation or external scenario information change unit 30 (for example, a current time determination unit that determines whether scenario information has been changed by time 31), a scenario analysis unit 24 that analyzes change information from the scenario information, and an animation playback unit 25 that controls the display form of the original image based on the analyzed scenario information and plays back an animation. The animation reproduced by the animation reproducing unit 25 is displayed by a display means such as an LCD (not shown).

  FIG. 7 is a flowchart showing the procedure of the animation reproduction operation of the image reproduction unit of the mobile terminal according to Embodiment 1 of the present invention. The JPEG image data in which the digital watermark information is embedded by the image generation apparatus 10 is acquired from the memory 50 (step S201) and developed in the RAM (not shown) of the control unit 60 (step S202).

  Next, the image data is decoded by the variable length decoding unit 21 (step S203), and the DCT coefficient acquisition unit 22 extracts DCT coefficients and embedded information (step S204). Further, the information separator 23 separates the extracted embedded information based on a predetermined rule, and acquires control point information, scenario information, and voice information (step S205). Through the above procedure, control information necessary for reproducing the morphed image is separated from the image data.

  The following is the procedure related to the reproduction of the morphing image. Here, for example, when the scenario information changing unit 30 is configured to change the reproduction speed of the morphing image according to the time, the current time The determination unit 31 determines the current time (step S206), and adds change information to the scenario information when the setting condition is met (step S207). On the other hand, if they do not match, the process proceeds directly to step S208.

  Next, the scenario analysis unit 24 analyzes the scenario information (step S208). Based on the analysis result, reproduction of the morphing image is started by the animation reproduction unit 25 (step S209) and displayed as a telephone standby screen of the portable terminal 100 (step S210). By the above procedure, the morphing image can be reproduced based on the extracted scenario information or the scenario information to which the change is added by the scenario information changing unit 30.

  By the way, as an example of scenario information change in the scenario information changing unit 30, the following application examples can be set in addition to an example in which a morphing image that operates differently according to the above time is displayed on the standby screen.

  FIG. 8 is a diagram showing another functional configuration of the scenario information changing unit of the mobile terminal according to Embodiment 1 of the present invention. The scenario information changing unit 30 is provided with a personal phone book determination unit 32, and scenario information is set for each individual registered in the phone book stored in the memory 50. Therefore, when the mobile terminal 100 receives a call, it is possible to reproduce a morphing image of a different scenario depending on the caller.

  FIG. 9 is a diagram showing still another functional configuration of the scenario information changing unit of the mobile terminal according to Embodiment 1 of the present invention. The absence information recording / reproducing determination unit 33 is provided in the scenario information changing unit 30, and unique scenario information is set according to the transmission source and content of the recording to be reproduced, the recording time, or the like. Therefore, at the time of absence recording recording / playback of the mobile terminal 100, it is possible to play back morphing images of different scenarios depending on the transmission source, the situation at the time of recording, and the like.

[Embodiment 2]
FIG. 10 is a diagram showing a schematic configuration of the mobile terminal and the server according to Embodiment 2 of the present invention. With reference to the figure, a mobile terminal and a server having a configuration in which the image generation apparatus is mounted on a server connected to be communicable, not a mobile terminal, will be described. The portable terminal 200 mainly includes an image playback unit 20, a scenario information change unit 30, a camera 40, a memory 50, a control unit 60, a telephone function unit 70, and a communication unit 80. The server 300 is mainly composed of the image generation device 10, a memory 90, a control unit 91, a communication unit 92, and the like.

  Since the function of each part of the portable terminal 200 is the same as that of the portable terminal 100 of Embodiment 1, description is abbreviate | omitted. Further, the configuration and functions of the image generation apparatus 10 of the server 300 are the same as those in the mobile terminal 100 of the first embodiment, and thus description thereof is omitted.

In addition, the control unit 91 performs overall control of the operation of the entire server by executing a control program. Furthermore, the communication unit 92 is connected to the communication unit 80 of the mobile terminal 200 via the Internet network 400, a mobile phone ground base station 500, and the like.

  FIG. 11 is a flowchart showing the procedure of the control information embedding operation of the portable terminal and the server in the second embodiment of the present invention. First, the face image data of the subject is photographed by the camera 40 of the mobile terminal 200 (step S301), and upon receiving an operation input from the operator of the mobile terminal 200, the control unit 60 transmits the captured still image data to the communication unit 80. To the server 300 (step S302).

  The server 300 receives still image data via the communication unit 92 (step S303), and the image generation apparatus 10 embeds control information or the like in the received still image data. Note that the procedure from step S304 to step S317 is the same as that from step S102 to step S115 in the flowchart of FIG.

  The JPEG image data in which control information and audio information are embedded as digital watermark information is transmitted from the server 300 to the mobile terminal 200 (step S318), and the mobile terminal 200 has embedded morphing image scenario information and the like as digital watermark information. JPEG image data is received (step S319).

  Through the above procedure, even if the control information necessary for generating the morphing image cannot be embedded on the mobile terminal side, the digital watermark embedded image data that can reproduce the morphing image can be acquired for the captured still image data. That is, even if the camera-equipped mobile phone does not have an application for generating a morphing image, the morphing image can be reproduced by acquiring the image data after the digital watermark embedding process from the server. The reproduction of the morphing image is executed by extracting control information embedded as digital watermark information, and a program (application) for this purpose is required. In the above procedure, still image data captured by the camera 40 is transmitted from the portable terminal 200 to the server 300. However, still image data captured in advance and stored in the memory 50 may be transmitted. .

  FIG. 12 is a flowchart showing the procedure of the animation reproduction operation of the image reproduction unit of the portable terminal according to Embodiment 1 of the present invention. The digital watermark embedded image data generated by the image generation device 10 of the server 300 is downloaded to the memory 50 of the mobile terminal 200 via the communication unit 92 of the server 300, the Internet network 400, the mobile phone network, and the like (step S401). . The procedure from step S402 to step S410 is the same as that from step S202 to step S210 in the flowchart of FIG. According to the above procedure, the morphing image can be reproduced based on the extracted scenario information or the scenario information changed by the scenario information changing unit.

  In the above embodiment, JPEG is used as an image compression method. However, other compression methods that can embed digital watermarks in DCT coefficient blocks such as control point information and scenario information may be used.

  By the way, even if an information terminal not equipped with the morphing image generation apparatus of the present invention receives still image data embedded with control point information, scenario information, and audio information as digital watermark information, the still image is simply displayed on the screen. Just do. That is, a mobile terminal or server equipped with the image generation apparatus of the present invention can transmit and receive image data without adversely affecting existing mobile terminals.
