[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. 100 is a stereoscopic image display device,
110 is an infrared remote controller. The viewer can operate the infrared remote control 110 to specify a television channel or an external input 105 that the user wants to view.

After receiving an infrared command emitted from the infrared remote controller 110 by the infrared receiving sensor 111 of the three-dimensional image display device 100 and performing a decoding process, the command is sent to a microcomputer (CPU) 112 for controlling the entire channel control and the like. Transfer commands. CPU112
Analyzes the command and controls the tuner 102 to tune to the indicated channel. Or external input 1
The selector 104 is switched so as to select 05. When stereoscopic television broadcasting is selected, the antenna 101
The three-dimensional television broadcast wave is received, and the designated channel is tuned and selected in the tuner 102.

The tuner 102 selects only a signal of a designated channel without selecting a signal of another channel, converts the signal into an intermediate frequency which is a processing frequency band of the demodulation processing circuit 103, and outputs it to the demodulation processing circuit 103. Demodulation processing circuit 1
03 demodulates a stereoscopic video signal including stereoscopic character data in a modulated format, extracts a stereoscopic video signal itself including stereoscopic character data, and outputs the extracted stereoscopic video signal to the selector 104.

FIG. 2 shows an example of a data structure of one frame of a stereoscopic video signal including stereoscopic character data.
The data structure is roughly divided into a three-dimensional character data part and a three-dimensional video data part. The three-dimensional character data part is composed of the following data. (1) Spatial coordinates of the starting point (2) Spatial coordinates of the ending point (3) Character attribute information indicating the size, type, color, etc. of the character (4) Character strings These sets are defined as ((1) Spatial coordinates of the starting point, (2) spatial coordinates of the end point, (3) character attribute information, (4) character string).

For example, in the case of a three-dimensional character "B" as shown in FIG. 3A, the three-dimensional character data portion is represented by (start point... (Xs,
Ys, Zs), end point… (Xe, Ye, Ze), attribute… Gothic normal, green,
Character string ... "B"). Also, a plan view of the three-dimensional character as viewed from the front will be represented as shown in FIG. If the character string "B" is changed to the character string "Boon" without changing the start point, and the end point is changed from (Xe, Ye, Ze) to the end point (Xe1, Ye1, Ze1), the set of three-dimensional character data becomes , (Start point ... (Xs, Ys, Z
s), end point ... (Xe1, Ye1, Ze1), attribute ... Gothic ordinary, green,
Character string ... "Boon").

On the other hand, the stereoscopic video data section is composed of, for example, a set of a left-eye image and a right-eye image. Selector 10
Among the outputs of 4, the stereoscopic video signal is output to the video signal processing circuit 106 and the character information decoder 107, and the audio signal is output to an audio processing circuit (not shown).

The video processing circuit 106 performs processing required for stereoscopic display on the stereoscopic video data section, and outputs the processed data to the synthesizer 108. The character information decoder 107 decodes the three-dimensional character data, converts the three-dimensional character data into desired left-eye images and right-eye images, and outputs them to the synthesizer 108. For this conversion, for example, three-dimensional computer graphic (3DCG) technology can be used. The synthesizer 108 synthesizes a stereoscopic video based on the two inputs and outputs the synthesized video to the stereoscopic display device 109. 3D display device 1
09 is a left-eye image and a right-eye image, respectively,
Display only to the right eye and display in 3D.

FIGS. 4A and 4B show images when the three-dimensional character data shown in FIGS. 3B and 3C are transmitted in this order. The three-dimensional image serving as the main screen is a scene in which one car runs away from the back to the front. With the movement of the car, the state moves from FIG. 4A to FIG. 4B, and the three-dimensional character string changes from "B" to "Boon", and the front of the character string is displayed along the road on which the car runs. As a result, a character display with an increased presence in motion can be realized. Similarly,
As shown in FIGS. 5 (a) and 5 (b), a structure having a plurality of sets of three-dimensional character data and a set in which not only the spatial coordinates of the start point and the end point but also the spatial coordinates indicating the position of the speaker are added. By displaying subtitles in a balloon shape and designating a balloon of one person to cover the balloon of another person, or by changing the size of characters, it is possible to give a further sense of realism.
Therefore, when the stereoscopic video signal is transmitted, the stereoscopic video display device 100 can stereoscopically display the subtitles in, for example, a balloon shape as shown in FIG. The speech balloon of husband B is displayed behind the speech balloon of A, and each speech balloon is displayed in the vicinity of each speaker, and it can be seen in the form of a speech balloon that the speech is emitted from that speaker.

In the above description, information is indicated by character strings.
A graphic data string of the character itself may be used as the three-dimensional character data part. In addition, although the description has been made using the two-lens image method as a stereoscopic image, the present invention is not limited to this, and the present invention is effective for other stereoscopic image methods. The speech bubble
Although the description has been made in the case where characters are displayed on an opaque background, translucent or transparent display may be performed by applying a technique such as α blending. When the observer operates the infrared remote controller 110 to give an instruction, the CPU 112
Controls the synthesizing characteristics of the synthesizer 108 so that the video signal processing circuit 10
Control can be performed such that the output of the sixth side is output to the display device 109 as it is. With this control, the three-dimensional character information can be prevented from being displayed. When the observer operates the infrared remote controller 110 to give an instruction, the channel control CPU 1
Numeral 12 can also control the decoding operation of the character information decoding circuit 107 to display a conventional flat character instead of a three-dimensional character.

FIG. 7 shows a stereoscopic video display device 200 according to another embodiment of the present invention. In the following embodiments, the same parts as those in the above embodiment are denoted by the same reference numerals and described.

The current broadcast channel tuned and selected by the tuner 102 is demodulated by the demodulation processing circuit 203 and becomes, for example, a composite video signal (2D signal) and left and right audio signals, which are output to the selector 104. Selector 104
Outputs the demodulated composite video signal (2D signal) to the video signal processing circuit 206 and the character information decoder 207. The selector 104 outputs the left audio signal of the audio signal to the band-pass filter (BPF1) 210, and outputs the right audio signal to the band-pass filter (BPF1).
2) Output to 211.

The video signal processing circuit 206 extracts a stereoscopic information component from the composite video signal (2D signal) and converts it into a stereoscopic video signal. As an example of the video signal processing circuit 206, there is a “method of generating a three-dimensional video from a two-dimensional video” disclosed in Japanese Patent Application Laid-Open No. 8-149517.

The character information decoder 207 is a circuit similar to the character multiplex decoder used in the conventional teletext compatible television, decodes the character information data superimposed during the vertical blanking period, and performs a display position control circuit. 208.

FIG. 8 shows the characteristics of the band-pass filters 210 and 211. In particular, it is a band-pass filter having a characteristic of extracting a signal in a voice band that a person utters in a conversation, and having similar characteristics. The pass band is a sound frequency range of 40 Hz to 4 kHz during normal conversation of a human. Bandpass filters 210, 21
1 are output to the sound localization position detection circuit 209, respectively.

The sound localization position detection circuit 209 detects which side of the left or right speaker is present depending on the difference between the left and right sound levels, and determines the position of the speaker in any position in the depth direction based on the delay state of the left and right sounds. Detect if it exists.

For example, if a sound signal having a similar waveform as shown in FIG. 9 is shifted in phase by time t1 between the left and right signals, depending on the time, it may be the voice of the speaker on the right side of the screen or the speaker on the left side. You can judge whether it is the voice of. That is, in the example of FIG. 9, since the right sound pressure is increased first, the speaker is located on the right side. Alternatively, it may be determined based on the level of the sound pressure whether it is located before or after.

In response to the detection result output from the sound localization position detection circuit 209, the display position control circuit 208 expands the two-dimensional character information data output from the character information decoder 207 as a three-dimensional character into a three-dimensional display space and synthesizes it. Output to the container 108.

The character information data is stored in the display position control circuit 20.
At 8, the display position is controlled. In the control of the display position, the coordinates of the start point and the end point are controlled as described with reference to FIG. 3, FIG. 4, and FIG. Depending on the size of the depth information,
Overlay display as shown in FIG. 5 is also performed.

By the above operation, the caption display at the time of inputting a two-dimensional image such as the conventional text multiplex broadcast can also be displayed in three-dimensional characters. Also, when the observer operates and gives an instruction to the infrared remote controller 110, the CPU 112 controls the combining characteristics of the combiner 108 and does not combine the three-dimensional character information on the character information decoder side with the video signal processing circuit 206 side. The output can be controlled to be output to the display device 109 as it is. With this control, the three-dimensional character information can be prevented from being displayed. Also,
When the observer operates the infrared remote controller 110 to give an instruction, the CPU 112 can also control the display position control operation of the display position control circuit 208 so that the display position is not a three-dimensional character but a conventional flat character display.

In this embodiment, a band-pass filter is used. However, it is also possible to use an audio component analysis technique such as fast Fourier transform (FFT). If the output from the audio localization position detection circuit 209 is undefined, the two-dimensional character display position included in the output data of the character information decoder 207 is set as the display position, and the stereoscopic character display is inserted into the stereoscopic video. It is sufficient to use a three-dimensional character whose depth is limited to the extent that no failure occurs. Furthermore, if only the operation of not resetting the display position of the three-dimensional character using the two-dimensional character display position information is performed, the bandpass filter 210,
211, the sound localization position detection circuit 209 is unnecessary, and the display position control circuit 208
The same operation as in the case where the output from 9 is undefined may be performed.

FIG. 10 shows a stereoscopic video display apparatus 300 according to another embodiment of the present invention. The video signal processing circuit 206 converts the left-eye image and the right-eye image into
8 and the depth information extraction circuit 301. The depth information extraction circuit 301 extracts depth information of an image in the stereoscopic display space displayed on the display device 109 and outputs the extracted information to the depth information inclination detection circuit 302. The depth information inclination detection circuit 302
The inclination state of the depth information is detected, and the outline of the speaker is determined based on the content, and the display position of the character information data is set according to the outline position. That is, the display position control circuit 303 controls the display position of the character closer to the speaker based on the output of the depth information inclination detection circuit 302.

FIG. 11 is a diagram for explaining the mechanism of depth information extraction, showing the screen surface of the display device and the surface of the viewer's eyes cut horizontally. The dashed line is the line of sight of the observer. The left-eye image is represented by a square, the corresponding right-eye image is represented by a circle, and the stereoscopic image perceived by the observer is represented by an equilateral triangle. If the left-eye image and the right-eye image are at the positions L1 and R1, respectively, the stereoscopic image is felt at the position c (behind the screen). If the left-eye image and the right-eye image are at L2 and R2, the stereoscopic image is felt at the position a (on the screen). If the left-eye image and the right-eye image are at L3 and R3, the stereoscopic image is felt at the position b (front of the screen).
As can be seen from this figure, the depth information (distance from the screen in FIG. 11) for a certain stereoscopic image is obtained by a geometric operation. By this principle, depth information can be detected, for example, for each pixel block. The next depth information inclination detection circuit 302 obtains the inclination of the depth information, sets a point whose value (absolute value) is equal to or larger than a predetermined threshold value as a candidate for the outer edge of a person who is a speaker, and obtains the depth information of that point. At the same time, the data is output to the display position control circuit 303.

Now, two persons (x) shown in FIG.
= X1 position and x = x2 position) are images in conversation. As shown on the left side of FIG. 12 (a), x, y, z
Set the coordinates. It is considered that it is preferable to calculate the gradient of x and y two-dimensionally for calculating the gradient of the depth information. However, for simplification of description, the description will be made assuming that the gradient is calculated only in the x direction. Here, with respect to the (x, y, z) = (0, y1, 0) plane which is the height near the face of the person, the change in the depth information in the x direction is schematically shown in the graph of FIG. become.

When the inclination of the depth information is obtained based on this data, the distribution is as shown in the graph of FIG. A portion exceeding a predetermined threshold value is a candidate for the outer edge portion of the person.
The display position control circuit 303 calculates an appropriate character display position from the two-dimensional display position of the character obtained from the character information decoder 207 and the candidate for the outer edge of the person from the depth information inclination detection circuit 302, and generates a three-dimensional character. Output to the synthesizer 108.

In this way, a three-dimensional character display can be performed. Also, when the observer operates and gives an instruction to the infrared remote controller 110, the CPU 112 controls the combining characteristics of the combiner 108 and does not combine the three-dimensional character information on the character information decoder side with the video signal processing circuit 206 side. The output can be controlled to be output to the display device 109 as it is. With this control, the three-dimensional character information can be prevented from being displayed. Also,
When the observer operates and gives an instruction to the infrared remote controller 110, the channel control CPU 112 can also control the decoding operation of the character information decoding circuit 207 to display the conventional flat character instead of the three-dimensional character.
Here, a description has been given of the case of receiving 2D video text broadcast, but stereoscopic video display or package media to which only planar text information is added can also perform stereo text display in the same manner.

FIG. 13 shows a stereoscopic video display apparatus 400 according to still another embodiment of the present invention. The process up to the extraction of the depth information is the same as in the previous embodiment. When the front image detection circuit 401 has a depth information distribution shown in FIG.
The vicinity of x1 and the vicinity of x2 of the x coordinate continuously exceed a predetermined threshold in a certain range, and a human image near x1 and x2 on the near side is detected. The coordinates corresponding to the outer edge of the detected human image are output to the display position control circuit 402.

The display position control circuit 402 calculates an appropriate character display position from the two-dimensional display position of the character obtained from the character information decoder 207 and the candidate for the outer edge of the person from the front image detection circuit 401 to generate a three-dimensional character. And outputs the result to the synthesizer 108.

Even in the above embodiment, it is possible to detect the front-back relationship between the surrounding image and the human image and the outer edge. The CPU 112 controls the synthesizer 108 so that character information is not displayed, and the display position control circuit 40
It is also possible to control to display character information in two dimensions instead of three-dimensionally by controlling 2 in the same manner as in the above-described embodiment.

FIG. 14 shows an example of a stereoscopic video display device 500 according to still another embodiment of the present invention. By the operation of the observer, the infrared sensor 11
1 is sent to the CPU 112
Controls the selector 104 to select the external input terminal 105 side. A video signal from a video playback device (not shown) is input to the external input terminal 105.

Now, in high-efficiency multimedia coding,
For example, MPEG-4 standardization work is in progress. In MPEG-4, the concept of VOP (Visual Object Plane) has been introduced. When an image to be encoded is composed of a plurality of visual objects, each is individually compressed and encoded as a VOP to realize highly efficient encoding. For example, there is a case where a portrait image and a background image of the avant-garde are divided into two VOPs and encoded.

Consider a case in which a person image shown in FIG. 15 is divided into two VOPs and encoded using a background image as a background image and a background image as a background image. The video signal processing circuit 503 has, for example, the function of an MPEG-4 decoder, and includes a decoding phase in which the avant-garde image and the background image are individually restored during the video signal processing. Further, the video signal processing circuit 503 stereoscopically configures the video so that the avant-garde image is displayed forward and the background image is displayed in the back, outputs the video to the synthesizer 108, and outputs the decoded video to the avant-garde image extraction processing circuit 501. Output. The avant-garde image extraction circuit 501 extracts the avant-garde image from each image of the decoded video, and outputs it to the avant-garde image end detection circuit 502. Video signal processing circuit 5
If the avant-garde image can be extracted as a by-product at 03, the avant-garde image extraction circuit 501 is unnecessary.

The avant-garde image edge detection circuit 502 detects the edge from the extracted avant-garde image. As shown in FIG.
The boundary between the area where the avant-garde human image exists and the area where the human image does not exist, that is, the outer periphery is detected, and the display position control circuit 50 is detected.
Output to 4.

On the other hand, apart from the encoding / decoding method, the character information decoder 505 decodes and displays the character information accompanying the video signal by an appropriate decoding method as in the case of the character information decoder 207 of the above-described embodiment. Output to the position control circuit 504. Display position control circuit 504
Is developed to display the three-dimensional character information at a position corresponding to the outer edge of the avant-garde image as shown in FIG.
Output to

As described above, three-dimensional display of character information becomes possible. The CPU 112 controls the synthesizer 108 to
It is also possible to control not to display the character information, and to control the display position control circuit 504 to display the character information not two-dimensionally but two-dimensionally, similarly to the above-described embodiment.

In each of the embodiments shown in FIGS. 7, 10, 13, and 14, processing for detecting the edge of the image from the depth information and the front image, and detecting the edge of the avant-garde image from the avant-garde image is performed. . However, the present invention is not limited to such an embodiment. Since the character information itself may include depth information, the display position of the character in the depth direction is used by using the depth information. May be determined. When the outline of the image is further known, the present invention is not limited to the above method. A motion vector known by a moving image processing technique may be detected, and the outline of the image may be detected from the process of detecting the motion vector. Further, even in the transmission / reception mode of the three-dimensional spatial coordinate position, the three-dimensional vector information may be transmitted and received, and the three-dimensional image processing and the three-dimensional character processing may be performed based on the three-dimensional vector information. is there.
