  The communication I / F 118 is a communication interface with the external terminal connected to the terminal 117, and performs conversion into a format such as a control signal and data between the control unit 114 and the external terminal.

  The camera module 119 is provided, for example, on the lower front side or the upper front side of the stereoscopic video processing device 110. The camera module 119 includes a camera 119a, a face detection unit 119b (detection module), a nonvolatile memory 119c, an identical person determination unit 119d, and a position calculation unit 119e.

  The camera 119a captures an area including the front of the stereoscopic video processing apparatus 100. The camera 119a is, for example, a CMOS image sensor or a CCD image sensor.

  The face detection unit 119b detects the user's face from the video imaged by the camera 119a. The face detection unit 119b divides a captured image into a plurality of areas, and performs face detection on all the divided areas.

  A known method can be used for face detection by the face detection unit 119b. For example, an algorithm for face recognition can use a method of directly comparing visual features geometrically. The face detection unit 119b stores information on the detected feature points of the face in the nonvolatile memory 119c.

  Information on facial feature points detected by the face detection unit 119b is stored in the nonvolatile memory 119c.

  The same person determination unit 119d determines whether the facial feature point detected by the face detection unit 119b is already stored in the nonvolatile memory 119c. The same person determination unit 119d determines that the same person has been detected when the feature point is already stored in the nonvolatile memory 119c. The same person determination unit 119d determines that the person is not the same person when the feature point is not stored in the nonvolatile memory 119c. By this determination, it is possible to prevent the guide Y from being displayed again for the user who has already been detected by the detection unit 119b.

  The position calculation unit 119e determines the position (α, β) on the image of the user who detected the face by the face detection unit 119b and the camera 119a and the user when the same person determination unit 119d determines that they are not the same person. The position coordinates (X, Y, Z) in the real space are calculated from the distance γ. A known method can be used to calculate the position coordinates in the real space. In the present embodiment, the upper left corner of the image captured by the camera 110a is the origin (0, 0), and the α axis is set in the horizontal direction and the β axis is set in the vertical direction. The coordinates in the real space are such that the center of the display surface of the video display unit 113 is the origin (0, 0, 0), the X axis in the horizontal and horizontal directions, the Y axis in the vertical direction, and the display surface of the video display unit 113. Set the Z axis in the normal direction.

  From the captured image, the position (α, β) of the user in the vertical and horizontal directions is known. The distance from the camera 119a to the user can be calculated from the distance from the right eye to the left eye of the face. Usually, since the distance between the right eye and the left eye of a human is about 65 mm, the distance γ from the camera 119a to the user can be calculated if the distance between the right eye and the left eye in the captured image is known.

  If the position (α, β) of the user on the video and the distance γ from the camera 119a to the user are known, the position coordinates (X, Y, Z) of the user in real space can be calculated. For example, the real space distance is obtained in advance from the real space distance per pixel of the camera 119a, and the number of pixels from the origin on the video to the user's position is multiplied by the real space distance per pixel. The position coordinates (X, Y, Z) of the user in real space can be calculated.

  The control unit 114 includes a ROM (Read Only Memory) 114a, a RAM (Random Access Memory) 114b, a nonvolatile memory 114c, and a CPU 114d. The ROM 114a stores a control program executed by the CPU 114d. The RAM 114b functions as a work area for the CPU 114d. Various setting information, viewing zone information, and the like are stored in the nonvolatile memory 114c. Viewing zone information is coordinate (X, Y, Z) data of a viewing zone in real space.

  FIG. 3 is an overhead view of the coordinate (X, Y, Z) data of the viewing zone in the real space stored in the nonvolatile memory 114c. In FIG. 3, white rectangular ranges 201a to 201e are regions where a stereoscopic image can be recognized as a three-dimensional image, that is, a viewing zone (hereinafter, the rectangular ranges 201a to 201e are referred to as viewing zones 201a to 201e). On the other hand, the hatched area 202 becomes an area where the user cannot recognize the image as a three-dimensional image, that is, outside the viewing area, due to the occurrence of so-called reverse viewing or crosstalk.

  A broken line 203 in FIG. 3 represents the boundary of the imaging range of the camera 119a. That is, the range actually captured by the camera 119a is a range below the broken line 203. For this reason, the storage in the nonvolatile memory 114c may be omitted for the upper left and upper right ranges from the broken line 203.

  The control unit 114 controls the entire stereoscopic video processing apparatus 100. Specifically, the control unit 114 controls the operation of the entire stereoscopic video processing apparatus 100 based on operation signals input from the operation unit 115 and the light receiving unit 116 and setting information stored in the nonvolatile memory 114c. For example, when the user depresses the calibration key 3 a of the remote controller 3, the control unit 114 displays the above-described calibration image on the video display unit 113.

(Operation of the stereoscopic image processing apparatus 100)
FIG. 4 is a flowchart showing the operation of the stereoscopic video processing apparatus 100. FIG. 5 is an explanatory diagram of the optimum viewing position. FIG. 6 is a calibration image displayed on the video display unit 113. Hereinafter, the operation of the stereoscopic video processing apparatus 100 will be described with reference to FIGS.

  When the user depresses the calibration key 3a of the remote controller 3, an infrared signal corresponding to the depressed calibration key 3a is emitted (step S101). The light receiving unit 116 receives an infrared signal emitted from the remote controller 3. The light receiving unit 116 outputs an operation signal (calibration image display signal) corresponding to the received infrared signal to the control unit 114.

  When receiving the calibration image display signal, the control unit 114 instructs the camera module 119 to start imaging. The camera module 119 images the front of the stereoscopic video processing apparatus 100 with the camera 119a based on an instruction from the control unit 114 (step S102).

  The face detection unit 119b performs face detection on the video imaged by the camera 119a (step S103). The face detection unit 119b divides a captured image into a plurality of areas, and performs face detection on each area. The face detection unit 119b stores information on the detected feature points of the face in the nonvolatile memory 119c (step S104). Note that the face detection unit 119b performs face detection periodically (for example, every several seconds to several tens of seconds) for the video imaged by the camera 119a.

  The same person determination unit 119d determines whether or not the facial feature point detected by the face detection unit 119b is already stored in the nonvolatile memory 119c (step S105). If the feature point is already stored in the nonvolatile memory 119c (Yes in step S105), the camera module 119 returns to the operation in step S102.

  When the feature point is not already stored in the nonvolatile memory 119c (No in Step S105), the position calculation unit 119c determines the position coordinates (X, Y, Z) in the real space of the face detected by the face detection unit 119b. Is calculated (step S106). The position calculation unit 119c calculates position coordinates (X, Y, Z) of each face in the real space when a plurality of faces are detected by the face detection unit 119b. The position calculation unit 119c outputs the calculated position coordinates (X, Y, Z) in the real space to the control unit 114.

  When the position coordinate (X, Y, Z) is output from the position calculation unit 119c, the control unit 114 refers to the viewing zone information stored in the nonvolatile memory 114c, and selects the viewing zone closest to the position coordinate. Guess (step S107).

The above operation will be described with reference to FIG. In the example illustrated in FIG. 5, it is assumed that two users are detected in an image captured by the camera 119a. Of the viewing zones 201a to 201e, the control unit 114 has position coordinates (X ₁ , Y ₁ , Z ₁ ), (X ₂ , Y ₂ , Z) of the users P ₁ and P ₂ whose viewing zones 201b and 201c are two people. ₂ )).

The control unit 114 obtains the range of the viewing zone at the positions of the Z coordinates Z ₁ and Z ₂ of the users P ₁ and P ₂ . Next, the control unit 114 calculates a range on the video imaged by the camera 119a from the range of the viewing zone at the obtained Z coordinates Z ₁ and Z ₂ . A known method can be used to calculate the range on the video. For example, what is necessary is just to calculate in the reverse procedure when calculating the position coordinates of the user in the real space from the position of the user on the video.

  The control unit 114 generates an OSD signal so as to generate a video signal for displaying on the video display unit 113 a calibration image in which a guide indicating the calculated viewing zone range is superimposed on a video image captured by the camera 119a. The unit 109 is instructed. The OSD signal generation unit 109 generates an image signal of a calibration image based on an instruction from the control unit 114. The generated image signal of the calibration image is output to the video processing unit 112 via the graphic processing unit 108.

  The video processing unit 112 converts the image signal of the calibration image into a format that can be displayed on the video display unit 113 and outputs the converted signal to the video display unit 113. On the video display unit 113, a calibration image is displayed (step S108).

FIG. 6A shows a calibration image displayed on the video display unit 113. 6 (a), the guide _{Y 1} is a guide for the user _{P 1} in FIG. The guide Y ₂ is a guide for the user P ₂ in FIG. The users P ₁ and P _{2 make} their faces in the guides Y 1 and Y 2 according to the instruction X displayed on the video display unit 113. By aligning the faces in the guides Y1 and Y2, the users P1 and P2 can view a stereoscopic image in an appropriate position, that is, in a viewing zone where no reverse viewing or crosstalk occurs. The guides Y ₁ and Y ₂ are displayed at substantially the same height as the detected face heights of the users P ₁ and P ₂ . The viewing zone has almost no change in the vertical direction (X coordinate direction). For this reason, there is no problem in viewing a stereoscopic image even if it is displayed at substantially the same height as the detected face height of the users P1 and P2.

In the calibration image shown in FIG. 6A, it may be difficult for the users P ₁ and P ₂ to find out which of the guides Y 1 and Y 2 should be faced. In this case, as shown in FIG. 6 (b), the users P ₁ and P ₂ display the arrows Z ₁ and Z ₂ together so that the user Y ₁ or Y ₂ can know which face to face. You may make it do. When a plurality of users are detected, the shape and color of each guide Y ₁ and Y ₂ may be changed (for example, the guide Y ₁ is a rectangle and the guide Y ₂ is an ellipse). The guide (frame) Y may be indicated by a solid line. Although the guide Y _1, Y ₂ are displayed in a frame, if recognition user may be presented with another display method is not limited to the frame.

  After the calibration image shown in FIG. 6 is displayed, the control unit 114 determines whether the calibration key 3a or the end key of the remote controller 3 has been pressed by the user (step S109). This determination can be made based on whether or not an operation signal corresponding to pressing of the calibration key 3a or the end key of the remote controller 3 is received by the control unit 114.

  When the calibration key 3a or the end key is pressed (Yes in step S109), the control unit 114 instructs the OSD signal generation unit 109 to end the display of the calibration image, and the operation ends.

  As described above, the stereoscopic video processing device 100 according to the embodiment includes the camera 119a that captures an area including the front of the stereoscopic video processing device 100, and detects the user from the video captured by the camera. A calibration image in which a guide indicating the viewing zone closest to the user's position is superimposed on a video image captured by the camera 119 a is displayed on the video display unit 113.

  The user can easily view a stereoscopic video in an appropriate position, that is, in a viewing zone where no reverse viewing or crosstalk occurs, by simply aligning his / her face with the guide displayed on the video display unit 113. it can. Further, since the calibration image is displayed on the video display unit 113 simply by pressing the calibration key 3a of the remote controller 3, it is convenient for the user.

  Furthermore, since the viewing zone that is closest to the user's position is presented, the user can move to a position that is appropriate for viewing a stereoscopic image with a small amount of movement, and the convenience for the user is improved. Even when there are a plurality of users, a guide is displayed for each user. In addition, when a guide (arrow) is displayed so that the user knows which guide the face should meet, the user's convenience can be further improved because each user can easily understand which guide the face should meet. .

  Further, the same person determination unit 119d is provided, and it is determined whether or not the facial feature point detected by the face detection unit 119b is already stored in the nonvolatile memory 119c. If the feature point is already stored in the nonvolatile memory 119c, the position calculation unit 119e does not calculate the position of the user. For this reason, it is possible to prevent the guide Y from being displayed again for a user who has already been detected.
