FIG. 2 is a block diagram illustrating a main configuration of the imaging display device 100 of the present embodiment, and FIG. 3 is a cross-sectional view of the imaging display device 100 of the present embodiment as viewed from the side.
As shown in FIGS. 1 to 3, in the interactive communication system S, an imaging display device 100 and an external device 300 are connected via an electric communication line 200 such as the Internet.

The imaging display device 100 includes, for example, a display unit 1 and an imaging unit 2, and the imaging unit 2 captures a front area of the display unit 1 to acquire image data, and a human face is captured in the image data. The image frame F is set in the surrounding area of the position, and the image frame image data Fd of the area surrounded by the image frame F (hereinafter referred to as the image frame area) is transmitted to the external device 300 of the other party. By receiving the image data transmitted from the external device 300 and displaying it on the display unit 1, a dialog with the other party using the external device 300 is realized.
The external device 300 is configured to have the same function as the imaging display device 100, receives the image frame image data Fd transmitted from the imaging display device 100, displays it on the display unit 301, and displays the display unit 301. By capturing an image of the face of the other speaker using the image, obtaining image data, and transmitting the image data to the image display device 100, a dialogue with a person using the image display device 100 is realized.

The imaging display device 100 is, for example, a display unit 1 including a display screen 1a that displays an image based on image data transmitted from the external device 300, and a display unit 1 that is disposed on the back side of the display unit 1 from behind the display screen 1a. An imaging unit 2 that captures an image of a front area and acquires image data, a communication unit 3 that transmits and receives data to and from the external device 300, a control unit 4 that performs overall control of the imaging display device 100, and the like. Has been.
Here, the front area of the display unit 1 refers to an area facing the imaging unit 2 with the display unit 1 interposed therebetween, and a person who has a conversation with the other speaker faces the display screen 1a side in the front region. Then, the conversation is performed while viewing the face image of the other speaker displayed on the display screen 1a.

  The display unit 1 employs, for example, an LCD (Liquid Crystal Display) system, and a glass substrate 11 and a counter substrate 12 disposed at a predetermined interval with respect to the glass substrate 11 are bonded together. Is sandwiched between two polarizing plates 15 and 15, a liquid crystal layer 13 and the like are held between the glass substrate 11 and the counter substrate 12, and a light lamp (not shown) and a light guide are not shown on the back side. A backlight 14 composed of a light plate, a reflection sheet or the like is provided.

As shown in FIG. 4, a plurality of display pixels 11 a are arranged in a matrix on the glass substrate 11, while a counter electrode (not shown) is formed on the counter substrate 12. Although not shown, each display pixel 11a includes a pixel electrode formed so as to be connected to a signal line and a scanning line, a thin film transistor (TFT) for driving the pixel electrode, and the like. Only the liquid crystal in the region enclosed between the electrode and the counter electrode changes the alignment direction in response to the fluctuation of the electric field between the electrodes, and the alignment film (not shown) formed on the polarizing plate 15, the pixel electrode and the counter electrode ) To pass or block light and function as a liquid crystal shutter.
Further, an RGB color filter (not shown) is disposed on the counter substrate 12 side, and color display is performed by the light emitted from the backlight 14 on the back side passing through the color filter.

The glass substrate 11, the counter substrate 12, and the like constituting the display unit 1 are provided with a plurality of minute openings 11 b as transmission parts, and an optical fiber 5 is connected to each of the openings 11 b. 1 is inserted and arranged from the back side to the front side.
The optical fibers 5 are provided in the same number as the openings 11b, and the back side of each optical fiber 5 is bundled to form an optical fiber bundle 5a. The end face of the optical fiber bundle 5a is an imaging unit 2 described later. It faces the image sensor. The optical fiber 5 is a communication cable for transmitting a signal by propagating light through a thin fiber core wire. The display unit 1 receives light from the end on the display unit 1 side through each opening 11b. The light (image) in the front area is received and supplied to the imaging unit 2 connected to the other end.

  The imaging unit 2 includes, for example, an imaging element 21 that photoelectrically converts light transmitted through the optical fiber 5, and an image processing unit 22 that performs predetermined image processing on image data converted into an electrical signal by the imaging element 21. The image processing unit 22 includes an image memory 23 that temporarily stores image data that has been subjected to image processing, and the like, and constitutes a part of an imaging unit.

  The imaging device 21 is a semiconductor device such as a CCD (Charged Coupled Device) or a CMOS (Complementary Metal-oxide Semiconductor), for example, and converts the intensity of light transmitted through the optical fiber 5 into an electrical signal for image processing. To the unit 22.

The image processing unit 22 includes, for example, an internal memory 221, a face feature storage unit 222 that stores a plurality of human face feature data, and the like, and image data captured via the optical fiber 5. Is subjected to predetermined image processing and output to the image memory 23.
Specifically, when image data converted into an electrical signal is input from the image sensor 21 in the image processing unit 22, the image data is stored in the internal memory 221 in units of frames, and in the image data for each frame. The face of the person is detected by comparison processing with the feature data stored in the face feature storage unit 222. When a person's face is detected, the position where the face is imaged in the entire frame is detected, and an image frame F is set in a predetermined peripheral area centered on the center of gravity P of the face. Only the frame image data Fd is cut out and output to the image memory 23.
Once the image frame F is set, face detection processing is performed only on the image frame region in the image data that is converted into an electrical signal from the image sensor 21 and sent. Then, only when the face position moves and the face is no longer detected in the image frame area, the detection range is expanded to the entire frame, and the face is detected, and the face is detected in the image data of the entire frame. In this case, the image frame F is set again. Further, when the position of the face moves within the image frame area that is the detection area, the image frame F moves to a position where the center of gravity P of the face is centered according to the movement of the face position.

  For example, the image memory 23 is configured to store a plurality of pieces of image data in units of frames, and temporarily stores the image frame image data Fd generated by cutting out the image frame area in the image processing unit 22. And output to the communication unit 3.

  The communication unit 3 includes, for example, a modem (MODEM: MOdulater / DEModulater) and transmits data such as image frame image data Fd to the external device 300 via an electric communication line 200 such as the Internet. As a result, it functions as part of the transmission means and receives data such as image data sent from the external device 300.

  The controller 4 includes an I / O port 41, a CPU (Central Processing Unit) 42, a RAM (Random Access Memory) 43, a ROM (Read Only Memory) 44, and the like.

  The CPU 42 executes various programs stored in the ROM 44 in accordance with input signals sent from the respective units via the I / O port 41 and outputs control signals based on the programs to the respective units via the I / O port 41. As a result, the overall operation of the imaging display device 100 is comprehensively controlled.

  The RAM 43 is used as a work area for the CPU 42 and temporarily stores various programs read from the ROM 44 and data related to these programs in the memory area.

The ROM 44 stores various processing programs executed by the CPU 42 and data such as various initial setting values related to the processing of each program.
Specifically, the ROM 44 stores programs such as an imaging program 44a, a face position detection program 44b, an image frame setting program 44c, and a communication program 44d.

The imaging program 44a is, for example, a program for causing the CPU 42 to realize a function of imaging the front area of the display unit 1 via the optical fiber 5 and acquiring image data by the imaging unit 2.
Specifically, the CPU 42 detects the front area of the display unit 1 that is sent via the optical fiber 5 while the person who is the subject in the front area of the display unit 1 is talking with the other party using the external device 300. Image data is continuously acquired at predetermined intervals (for example, 30 times / second) by photoelectrically converting light by the image sensor 21, and the acquired image data is sequentially output to the image processing unit 22.
The CPU 42 functions as an imaging unit together with the imaging unit 2 by executing the imaging program 44a.

The face position detection program 44b is, for example, a program for realizing a function of detecting a position at which a person's face is imaged with respect to image data acquired by the CPU 42 by executing the imaging program 44a.
Specifically, for example, when image data is input in the image processing unit 22, the CPU 42 stores the image data in the internal memory 221 in units of frames, and the face of the image data stored in the internal memory 221 is stored. By comparing the candidate area with the face feature data stored in the face feature storage unit 222, it is determined whether there is data similar to the stored face feature data, and a human face is imaged in the image data. It is judged whether it is done. Then, a binary edge image is generated by performing filter processing such as edge detection or binarization processing on the image data in which a human face is detected, and each pixel of the image is set in the x-axis direction, y Based on the projection histogram obtained by projecting in the axial direction, a region where the face is imaged is extracted.
Further, when the image frame F is set in the peripheral area of the face by executing an image frame setting program 44c described later, the CPU 42 detects the face in the image frame area of the image data, and the person moves. If no human face is detected in the image frame area, the face is detected for the entire frame of the image data.
The CPU 42 functions as a face position detection unit by executing the face position detection program 44b.

The image frame setting program 44c has a function of setting, for example, the image frame F in the peripheral area of the person's face based on the position of the person's face in the image data detected by the execution of the face position detection program 44b. This is a program to be realized. The image frame setting program 44c moves the position of the set image frame F in accordance with the movement of the face position.
Specifically, when the CPU 42 detects the position where the face is captured in the image data where the face of the person is detected, for example, by executing the face position detection program 44b, Centroid point P is detected, and an image frame F is set in a predetermined peripheral region with the centroid point P as the center. The surrounding area is a rectangular area composed of a predetermined number of pixels, and is set so that the person who is the subject is located at the approximate center of the image frame F. In addition, once the image frame F is set, the CPU 42 detects the center of gravity P of the face and moves the image frame F so that the center of gravity P is the center.
The CPU 42 functions as an image frame setting unit by executing the image frame setting program 44c.

Here, processing performed by the CPU 42 executing the image frame setting program 44c will be described in detail with reference to FIG.
FIG. 5 is a diagram illustrating image data generated by executing the imaging program 44a, the face position detection program 44b, and the image frame setting program 44c.
When the image data obtained by imaging the front area of the display unit 1 acquired by executing the imaging program 44a is input to the image processing unit 22, the CPU 42 stores the image data in the internal memory 221 in units of frames, and the face position detection program 44b. By executing the above, based on the comparison with the face feature data stored in the face feature storage unit 222, the human face detection process is executed on the image data to determine whether or not the face has been imaged. To do. When the CPU 42 determines that the face has been imaged, the CPU 42 specifies the area where the face is imaged in the entire frame and calculates the center of gravity P of the face. As shown in FIG. An image frame F is set in a predetermined peripheral area as a center. The image frame F is set, for example, in a rectangular area including a predetermined number of pixels (for example, horizontal 540 pixels × vertical 705 pixels), and is set so that the person's face is substantially in the center. . When the image frame F is set, the CPU 42 generates an image frame image data Fd by cutting out the image frame region from the entire frame of the image data, and outputs the generated image frame image data Fd to the image memory 23.

  Once the image frame F is set after the start of imaging, the CPU 42 detects the position of the face by executing the face position detection program 44b for the image frame area in the image data acquired by executing the imaging program 44a. I do. Then, as shown in FIG. 5B, when a person moves in the vertical direction or the horizontal direction and the center of gravity P of the face fluctuates in the image frame area, the center of gravity is changed as shown in FIG. The image frame F is moved so that P becomes the center of the image frame region. Also, as shown in FIG. 5D, when the person moves to a position outside the image frame F and no face is detected in the image frame area, the CPU 42 extends the detection range to the entire frame, Perform face detection processing. When the face is detected in the entire frame of the image data, the CPU 42 calculates the center of gravity P of the face and resets the image frame F as shown in FIG. That is, the image frame F is controlled so that the person is always located at the approximate center, and the image memory 23 stores only the image frame image data Fd where the person is positioned at the approximate center.

For example, the communication program 44d transmits to the CPU 42 the image frame image data Fd of the image frame area set by the execution of the image frame setting program 44c to the external device 300, and receives image data transmitted from the external device 300. It is a program that realizes the function to perform.
Specifically, the CPU 42 uses the communication unit 3 to transmit the image frame image data Fd generated by the execution of the imaging program 44a, the face position detection program 44b, and the image frame setting program 44c, and stored in the image memory 23, to the other party. And the image frame image data Fd transmitted from the external device 300 is received. The received image data is subjected to predetermined processing in each unit of the imaging display device 100, and an image based on the received image data is displayed on the display screen 1a of the display unit 1.
The CPU 42 functions as a transmission unit together with the communication unit 3 by executing the communication program 44d.

For example, the external device 300 is configured to have the same function as the imaging display device 100, and includes a display unit 301, a CPU 302, a ROM 303, and the like.
The CPU 302 of the external device 300 performs predetermined processing in each unit of the external device 300 on the received image frame image data Fd by executing the display control program 303a stored in the ROM 303, and the image frame image data Fd An image based on the image is displayed on the display unit 301. As a result, as shown in FIG. 6, the display unit 301 always displays an image in which a person's face is captured in the approximate center.

Next, image data acquisition / transmission operation processing will be described with reference to FIG.
In the image data acquisition / transmission operation process, the CPU 42 of the imaging display device 100 executes the imaging program 44a, the face position detection program 44b, the image frame setting program 44c, and the communication program 44d, and the CPU 302 of the external device 300 displays the image data. This is performed by executing the control program 303a.

First, the CPU 42 of the imaging display device 100 converts the light (image) in the front area of the display unit 1 input via the optical fiber 5 into an electrical signal by the imaging element 21 in the imaging unit 2, thereby generating an image. Data is acquired (step S1). Next, the CPU 42 performs a human face detection process on the entire frame of the image data acquired in step S1 in the image processing unit 22 (step S2), and determines whether or not a human face is detected. Judgment is made (step S3). If the CPU 42 determines in step 3 that no human face is detected (step S3; No), the CPU 42 returns to step S1 and repeats the above processing. On the other hand, when the CPU 42 determines in step S3 that a human face is detected (step S3; Yes), the CPU 42 calculates the center point P of the area where the face is imaged (step S4), and the center point P is the center. An image frame F is set in a surrounding area including a predetermined number of pixels (step S5).
Next, the CPU 42 cuts out the image frame area in the image data to generate image frame image data Fd (step S6), temporarily stores it in the image memory 23, and stores the image frame image data Fd stored in the image memory 23. Is transmitted to the external device 300 by the communication unit 3 (step S7).

  Next, in the imaging unit 2, the CPU 42 converts the light in the front area of the display unit 1 input via the optical fiber 5 into an electrical signal by the imaging element 21, and acquires image data (step S8). The CPU 42 performs a human face detection process on the image frame area of the image data acquired in step S8 in the image processing unit 22 (step S9), and determines whether or not a human face is detected. (Step S10). If the CPU 42 determines in step 10 that no human face is detected (step S10; No), the CPU 42 returns to step S2 and repeats the above processing. On the other hand, when the CPU 42 determines in step S10 that a human face is detected (step S10; Yes), the CPU 42 calculates the center point P of the area where the face is imaged (step S11), and the center point P is displayed. It is determined whether or not it has moved within the frame area (step S12). When the CPU 42 determines that the center of gravity P has not moved (step S12; No), the CPU 42 returns to step S6 and repeats the above processing. On the other hand, when the CPU 42 determines in step S12 that the barycentric point P has moved (step S12; Yes), the CPU 42 moves the image frame F so that the barycentric point P is at the center (step S13), and returns to step S6. Repeat the above process.

  When the CPU 302 of the external device 300 receives the image frame image data Fd transmitted via the telecommunication line 200 by the communication unit 3 of the imaging display device 100 in step S14, the CPU 302 performs predetermined processing in each unit of the external device 300. Then, the display unit 301 displays an image in which the face of the person based on the image frame image data Fd is captured at the approximate center (step S15), and the process ends.

According to the imaging display device 100 according to the present invention described above, in the image data acquired by the execution of the imaging program 44a by the CPU 42, the position where the face of the person is imaged by the execution of the face position detection program 44b is detected, Based on the position of the face, the image frame F is set in the peripheral region of the face by executing the image frame setting program 44c. Further, since the image frame image data Fd of the area surrounded by the image frame F in the image data is transmitted to the external device 300 by the execution of the communication program 44d, even if the position of the face is moved, the machine Therefore, only the image frame image data with the face image displayed in the center is transmitted without tracking. Therefore, the response speed is not inferior to the movement of the face position, and an image with a matched line of sight can be transmitted more reliably.
Further, the display unit 1 includes an opening 11b that transmits light input from the front region, and the CPU 42 captures an image of the front region of the display unit 1 obtained through the optical fiber 5 by executing the imaging program 44a. Since the image data is acquired in this manner, it is possible to more easily acquire the image data having the same line of sight, and to increase the degree of design freedom such as reducing the thickness of the imaging display device 100. Furthermore, since imaging is performed with light entering through the optical fiber 5 from the opening 11b, image data with a wide angle of view can be acquired.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the present embodiment, the imaging display device 100 has been described as having the LCD display unit 1, but it may be a PDP display, an organic EL display, or the like.
In addition, the imaging display device 100 is configured to transmit moving image data to the external device 300, but the image data may be a still image.
In addition, the image frame F has been described by using a configuration in which the image frame F is set to a peripheral region centered on the center of gravity P of the region where the face is imaged, but the image frame F is based on the center point of both eyes of the face. It may be set, or may be set based on the nose region of the face.
Further, the face detection method is not limited to the method of the above-described embodiment. For example, a face detection method based on a position of both eyes or a support vector machine (Support Vector Machine, SVM) A method of performing the determination may be used.
Further, the transmission part is not limited to the opening part 11b, and for example, it may be designed such that image data is acquired by light that passes through the glass substrate 11 or the like from the front area of the display part 1 and enters.
