In the present embodiment, when the call with the video phone 200 using video phone functions is ended, the address book registration portion 134 registers the still image or the video extracted by the image extraction portion 132, associating the registered image with address book information of the recipient party with whom the call was made.
The user interface portion 128 accepts operation inputs from the user of the video phone 100, and outputs images and audio transmitted from the recipient party side video phone 200 to the display 101 and the speaker 104.
The functional configuration of the video phone 100 according to the embodiment of the present invention is explained above with reference to FIG. 3. Next, operation of the video phone 100 according to the embodiment of the present invention will be explained.
4. Operation of Video Phone According to Embodiment of Present Invention
FIG. 4 is a flow chart illustrating the operation of the video phone 100 according to the embodiment of the present invention. Hereinafter, the operation of the video phone 100 according to the embodiment of the present invention will be explained with reference to FIG. 4.
When using the video phone 100 to make a call to the recipient party using video phone functions, first, the recipient party is selected by user operation (step S102). To select the recipient party, the video phone 100 may be operated using the remote control 150 etc. to directly input the telephone number of the recipient party, or the recipient party may be selected from the address book.
FIG. 5 is an explanatory diagram showing an example of an address book screen on the video phone 100 according to the embodiment of the present invention. The address book screen shown in FIG. 5 is displayed on the display 101 as a result of operation of the video phone 100 using the remote control 150. In a state in which the type of screen shown in FIG. 5 is displayed, the user of the video phone 100 can use the remote control 150 to operate the video phone 100 and select the recipient party.
The following explanation is an example in which a call is placed after selecting the top item “Grandpa, Grandma” as the recipient party on the address book shown in FIG. 5.
When the recipient party is selected in the above-described step S102, a connection is established with the recipient party selected in the above-described step S102 and a call with the recipient party is started (step S104). The connection with the selected recipient party may be established, for example, by generating call control information in the main block 126, transmitting the generated call control information from the transmission processing portion 122, and receiving a response from the recipient party side video phone 200 in the reception processing portion 124.
FIG. 6 is an explanatory diagram showing an example of a call screen on the video phone 100 according to the embodiment of the present invention. The call screen shown in FIG. 6 is displayed on the display 101 after the call has been started with the recipient party. As shown in FIG. 6, the call screen includes a home screen 162 and a recipient party screen 164.
The home screen 162 is a screen on which images taken by the camera 102 are displayed, and the images displayed on the home screen 162 are also displayed on the recipient party side video phone 200. Further, the recipient party screen 164 displays images of the recipient party taken by a camera of the recipient party side video phone 200. The images displayed on the recipient party screen 164 are images obtained as a result of decoding by the reception processing portion 124, and are displayed by the user interface portion 128. The user of the video phone 100 can make a call with the recipient party using video phone functions while watching the type of screen shown in FIG. 6.
Then, in the present embodiment, using the images transmitted from the recipient party side video phone 200 and obtained as a result of decoding by the reception processing portion 124, an image is automatically registered in the address book. By this type of automatic registration of the image in the address book, the image is stored in the telephone in advance, thus saving time and effort to edit video using a device other than the telephone, and the image can be easily registered. In the following explanation, an example is described in which a still image is registered in the address book.
When registering an image in the address book, the user may instruct a selected timing for image capture and the image extraction portion 132 may extract an image at the instructed timing from the images transmitted from the recipient party side video phone 200. Then, the address book registration portion 134 registers in the address book the image extracted by the image extraction portion 132. The image capture may be performed, for example, by operation of the remote control 150 by the user of the video phone 100. Furthermore, the number of images captured may be unlimited and repeatedly captured. When there is a plurality of captured images, the address book screen may successively display the captured images on the address book screen in a slide show format.
On the other hand, when registering an image in the address book, during the call with the recipient party, images transmitted from the recipient party side video phone 200 may be analyzed by the image extraction portion 132, a specific image may be extracted from the analysis results, and the extracted image may be registered in the address book by the address book registration portion 134. In the present embodiment, the following analysis process is performed.
From the image data of the recipient party, the image extraction portion 132 successively captures a still image at a predetermined time interval and extracts a still image (step S106).
The image extraction portion 132 performs face recognition processing on the image data of the recipient party, captures a frame in which a person is shown in the recipient party side image, and extracts the frame as a still image (step S108). The image extraction portion 132 performs face recognition processing by detecting facial features, such as eyebrows, eyes, nose, mouth etc. included in an image, and can use technology disclosed in Japanese Patent Application Publication No. JP-A-2008-152530, for example. For example, the image extraction portion 132 may perform face recognition processing on the image data of the recipient party, use the face recognition processing results to identify the size of the person's face shown on the recipient party side camera, capture a frame in which a large face is shown and extract the frame as the still image. Additionally, for example, the image extraction portion 132 may perform face recognition processing on the image data of the recipient party and recognize a facial expression of the person shown on the recipient party side camera. It may then capture a frame showing a smiling face and extract the frame as the still image.
The image extraction portion 132 performs face recognition processing on the image data of the recipient party and recognizes whether the recipient party is a child or an adult. It is set in advance whether to prioritize registration in the address book for an adult or a child, and a man or a woman. Then, a frame is captured based on the priority setting, and still image extraction processing is performed (step S110). Note that it may be determined whether the images included in the recipient party side image data are of an adult or not, and the sex of the person shown may be determined, by detecting the position of eyes, nose and mouth etc., for example, and based on the positional relationships between these facial features.
The image extraction portion 132 calculates the degree of change between frames of the recipient party image data and measures the intensity of movement of the recipient party images. If an image in which there is a large degree of change between frames, namely an image with intense movement, is extracted as a still image, a clear still image cannot be obtained due to camera shake or blurring of an object of the image. Therefore, an image in which there is a small degree of change between frames is extracted as the still image (step S112). Note that, the following methods may be used to measure the degree of change between frames. Each of the methods listed below may be used separately, or may be used in combination.
1. Whole screen motion vector quantity
2. Whole screen frame difference
3. Measurement of degree of movement by motion detection
4. Other frame difference/motion detection technology
Note that, these analysis processes are shown in FIG. 4 as a series of processes, but in the present invention, the analysis processes may be performed separately or a plurality of the analysis processes may be performed in combination.
During a call with the recipient party, when analysis processing of the image data of the recipient party by the image extraction portion 132 is complete and a still image is extracted, after the call is ended, the still image extracted by the image extraction portion 132 is registered in the address book by the address book registration portion 134. At this time, the still image is associated with the address book information corresponding to the recipient party. When the call with the recipient party is ended (step S114), the address book registration portion 134 registers the still image extracted by the image extraction portion 132 in the address book such that the still image is registered in association with the address book information corresponding to the recipient party (step S116).
FIG. 7 is an explanatory diagram showing an example of a screen displayed on the display 101 when, with the video phone 100 according to the embodiment of the present invention, the user instructs the video phone 100 to display the address book screen after a call with the recipient party is ended. FIG. 7 shows a case when an image is pasted by the address book registration portion 134 into the top item “Grandpa, Grandma.” By automatically registering images in the address book by the address book registration portion 134 in this way, images can be easily pasted into the address book.
The operation of the video phone 100 according to the embodiment of the present invention is explained above with reference to FIG. 4. In the operation of the video phone 100 according to the embodiment of the present invention shown in FIG. 4, the explanation describes an example in which a still image is registered in the address book. However, a video and not a still image may be registered in the address book. FIG. 8 is a flow chart illustrating the operation of the video phone 100 according to the embodiment of the present invention. Hereinafter, the operation of the video phone 100 according to the embodiment of the present invention will be explained with reference to FIG. 8.
In the same way as registering a still image in the address book, when the video phone 100 is used to make a call to the recipient party using video phone functions, first the recipient party is selected by user operation (step S122). To select the recipient party, the video phone 100 may be operated using the remote control 150 etc. to directly input the telephone number of the recipient party, or the recipient party may be selected from the address book.
When the recipient party is selected in the above-described step S122, a connection is established with the recipient party selected in the above-described step S122 and a call with the recipient party is started (step S124). The connection with the selected recipient party may be established, for example, by generating call control information in the main block 126, transmitting the generated call control information from the transmission processing portion 122, and receiving a response from the recipient party side video phone 200 in the reception processing portion 124.
When registering a video in the address book, the user may instruct a selected timing for video capture and the image extraction portion 132 may extract a video at the instructed timing from the videos transmitted from the recipient party side video phone 200. Then, the address book registration portion 134 registers the video extracted by the image extraction portion 132 in the address book. The video capture may be performed, for example, by operation of the remote control 150 by the user of the video phone 100. Furthermore, the number of videos captured may be unlimited. When there is a plurality of captured videos, the address book screen may successively display the captured videos on the address book screen in a slide show format.
On the other hand, when registering a video in the address book, during the call with the recipient party, videos transmitted from the recipient party side video phone 200 may be analyzed by the image extraction portion 132, a specific video may be extracted from the analysis results, and the extracted video may be registered in the address book by the address book registration portion 134. In the present embodiment, the following analysis process is performed.
From the image data of the recipient party, the image extraction portion 132 successively captures a video at a predetermined time interval and extracts a video for a selected time period (step S126).
The image extraction portion 132 performs face recognition processing on the image data of the recipient party (step S128). Face recognition processing may recognize, for example, that a person is shown on the camera of the recipient party side video phone 200, capture frames in which a person is shown and extract these frames as the video. Alternatively, for example, the processing may recognize the number of people shown on the camera of the recipient party side video phone 200, capture frames in which there are many or few people, and extract these frames as the video. Alternatively, for example, the processing may recognize the size of a person's face shown on the camera of the recipient party side video phone 200, capture frames in which a large face is shown and extract these frames as the video. Alternatively again, for example, the processing may recognize a facial expression of a person shown on the camera of the recipient party side video phone 200, capture frames showing a smiling face and extract these frames as the video. Note that, it may be determined whether the faces included in the recipient party side image data are smiling faces or not by detecting the position and shape of eyes, nose and mouth etc., for example, and the positional relationships and shapes of these facial features.
The image extraction portion 132 performs facial recognition processing on the image data of the recipient party and recognizes whether the recipient party is a child or an adult, and a man or a woman. It also recognizes the number of adults or children and the number of men or women shown. It is set in advance whether to prioritize an adult or a child, and a man or a woman, and frames including an adult or frames including a child, or frames including a man or frames including a woman are captured and extracted as the video (step S130).
The image extraction portion 132 calculates the degree of change between frames of the recipient party image data and recognizes to what degree the recipient party images are moving (the intensity of movement). Frames with a large degree of movement or frames with a small degree of movement are captured, and these frames are extracted as the video (step S132). Note that the methods for measuring the degree of change between frames described in step S112 above may be used here as methods for measuring the degree of change between frames.
Furthermore, recipient party voice data included in the recipient party image data may be analyzed by the main block 126. As a result of analysis by the main block 126, frames in which the recipient party's voice is loud are determined to be frames in which the conversation is lively, and the relevant frames are captured by the image extraction portion 132 and extracted as the video (step S134). Various methods can be used to perform the voice data analysis processing in step S134, and the present invention is not limited to a particular method.
Note that these analysis processes are shown in FIG. 8 as a series of processes, but in the present invention, the analysis processes may be performed separately or a plurality of the analysis processes may be performed in combination.
During a call to the recipient party, when analysis processing of the image data of the recipient party by the image extraction portion 132 is complete and the video is extracted, after the call is ended, the video extracted by the image extraction portion 132 is registered in the address book by the address book registration portion 134. At this time, the video is associated with the address book information corresponding to the recipient party. When the call with the recipient party is ended (step S136), the address book registration portion 134 registers the video extracted by the image extraction portion 132 in the address book such that the video is registered in association with the address book information corresponding to the recipient party (step S138).
The operation of the video phone 100 according to the embodiment of the present invention is explained above with reference to FIG. 8. In this way, by analyzing the recipient party image data by the image extraction portion 132, extracting a still image or a video and registering the extracted still image or video in the address book, images can easily be registered in the address book without saving images in advance in the video phone 100, and without performing editing of the video on a separate device.
Note that, in the above explanation, the recipient party image data is analyzed, a still image or a video is extracted and the extracted still image or video is registered in the address book. However, when the address book has a function to allow hearing of audio, audio data may be extracted and the extracted audio data may be registered in the address book.
Generally, when a call is started, the recipient party often uses a routine phrase, such as “Hello” or “XX (name) speaking.” Therefore, audio data is extracted by the main block 126 from immediately after the call has started to a predetermined point in time, and is registered in the address book. By registering the above-described audio data in this way, the audio can be played back on the screen displaying the address book, and the user can recall who the recipient party is.
The period registered in the address book, for example, may be from when the recipient party first speaks immediately after the call is started to the next period of silence. A period of silence may be determined by checking the microphone level, or by checking the content of the packet and determining whether or not it is silent.
Alternatively, the period registered in the address book may be from the start of the call for a predetermined time period (three to five seconds, for example). The time period of approximately this length is a sufficient time period to include a routine phrase from the recipient party, such as “Hello,” or “XX speaking.”
Note that, when registering audio in the address book, an icon indicating that audio has been registered (a microphone icon, for example), may be displayed on the address book screens shown in FIG. 5 and FIG. 7, to the left of the image or to the right of the name etc.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
5. Modified Example
In the present embodiment, for example, the image extraction portion 132 performs analysis processing on the image data from the recipient party and extracts a still image or videos. However, the number of still images and videos is not limited to one.
For example, the image extraction portion 132 performs analysis processing on the image data from the recipient party, and when a plurality of still images or videos that match prerequisites can be extracted, the address book registration portion 134 may register all the plurality of extracted still images or videos in the address book. Then, when displaying the address book in which the still images or videos are registered, the registered still images or videos may be displayed in a so-called slide show format.
Then, when displaying the still images or videos in the slide show format, an order of priority for the extracted still images or videos may be set when the image extraction portion 132 extracts the still images or videos. The following explanation describes a case in which the size of the face shown in the recipient party side camera in the above-described step S108 is recognized, and frames in which the face is large are captured and extracted as still images. In this case, the image extraction portion 132 may be set to accord highest priority to a frame in which the face is largest, and to lower the degree of priority the smaller the face is.
In addition, the explanation describes a case in which the expression of the person's face shown on the recipient party side camera in the above-described step S108 is recognized, and frames showing a smiling face are captured and extracted as still images. In this case, the image extraction portion 132 may be set to accord highest priority to a frame in which the face has the largest smile and to lower the degree of priority the smaller the smile on the face is.
The present invention can be applied to an information processing device, an information processing method and a computer program. In particular, it can be applied to an information processing device, an information processing method and a computer program that have video phone functions.
