Description

Video converter

This technical field relates to a video conversion device, and more particularly to a video conversion device that outputs a stereoscopically viewable video signal.

In recent years, in order to display a stereoscopically viewable video (stereoscopic video), technical development relating to a video conversion device has been advanced. When displaying a stereoscopic video, the video conversion device generates a left-eye video and a right-eye video based on content data recorded on a video medium such as an optical disk and sends the generated video to the video display device. The video display device alternately displays the left-eye video and the right-eye video.
Patent Document 1 discloses a video conversion device capable of displaying a stereoscopic video by presenting a right-eye video and a left-eye video having parallax to a user. The user synthesizes an image viewed through the right eye (right eye image) and an image viewed through the left eye (left eye image) in the brain, and recognizes it as a stereoscopic image.
Also, the video source may be a stereoscopically viewable video shot with a 3D camera, such as a video phone. The stereoscopically viewable video imaged by the 3D camera is transmitted as a video stream from its own video conversion device to the other video conversion device via a network or the like. Also, the other party's video can be received as a video stream by the own video conversion device via a network or the like. The video converted by the video conversion device is displayed on a display device such as a television. At this time, the display device may display its own video together with the video of the other party.

Hereinafter, embodiments will be described in detail.
(Embodiment 1)
1. Configuration of Stereoscopic Video Reproduction Display System Here, the video conversion system in Embodiment 1 will be described. FIG. 1 is an overall configuration diagram of a video conversion system such as a videophone according to the first embodiment. This video conversion system includes a communication device 100. In FIG. 1, a display device 300 is a display device such as a display for displaying a stereoscopic video. The communication device 100 converts its own video captured by the camera / microphone 200 and its surrounding video, and transmits the converted video to a medium such as a network. In addition, the communication apparatus 100 receives a partner's video and a video around the partner from a medium such as a network, and decodes the partner's video and the video around the partner. Further, the communication device 100 transmits a video signal to the display device 300, and the display device 300 displays a video based on the video signal.

The stereoscopic video is displayed by using a method of alternately transmitting the left (L) video / right (R) video in terms of time, that is, a sending method called frame sequential.
Next, the details of the communication apparatus 100 will be described with reference to FIG. FIG. 2 is a diagram showing details of the configuration of the communication device 100 in each embodiment described in this specification.
The communication device 100 is controlled by the control LSI 101 while using the flash memory 112 as appropriate. The communication device 100 is connected to the camera / microphone 200 via the USB interface 105. The communication device 100 is connected to the network via the network interface 103. The communication device 100 is connected to the display device 300 via the HDMI interface 107. The communication device 100 is connected to an input unit such as a remote controller 400 via the wireless light receiving unit 104. When the user operates remote controller 400, communication device 100 receives the signal from remote controller 400 and starts operation.

The camera / microphone 200 captures an image around the camera / microphone 200. The 3D camera 201 captures a 3D video, and the microphone 202 records audio. The encoder 203 encodes the 3D video imaged by the camera 201 and the audio recorded by the microphone 202, and converts them into stream data that can be transmitted. After the 3D video and audio are converted into stream data by the encoder 203, the stream data is output from the camera / microphone 200 to the communication apparatus 100 via an interface such as the USB interface 105.
The video signal input from the camera / microphone 200 to the communication apparatus 100 is controlled by the control LSI 101 and distributed to the network via the network interface 103. Here, the video signal distributed to the network is transmitted to a conversation partner in the form of a so-called videophone.

On the other hand, when the video signal of the partner user is received by the communication device 100, the video of the partner user is displayed on the display device 300. Here, the other user also uses a system similar to the above system to transmit / receive a stereoscopically viewable video stream captured by the camera via the network. Thereby, each user can make a videophone call with the partner user while viewing the video of the partner user displayed on the display device 300.
An image input to the communication apparatus 100 from the network via the network interface 103, for example, an image of the partner user, is decoded and visualized under the control of the control LSI 101. The video decoded here is output to the display device 300 via the HDMI interface 107.
At this time, an image input from the network to the communication device 100 via the network interface 103, for example, an image of the other user is synthesized with an image input from the camera / microphone 200 to the communication device 100 under the control of the control LSI 101. It is sent to the display device 300.

An image input to the communication apparatus 100 from the camera / microphone 200 and an image input to the communication apparatus 100 from the network via the network interface 103 are stereoscopically viewable images. The stereoscopic video signal output from the communication device 100 is output to the display device 300 via the HDMI interface 107. The HDMI interface 107 is preferably composed of a signal communication unit compatible with, for example, HDMI (High Definition Multimedia Interface) Ver1.4.
Display device 300 sends a switching signal for controlling the opening and closing of the shutters of the left and right lenses to stereoscopic glasses worn by the user. For example, the monitor 301 sends a switching signal to the stereoscopic glasses in accordance with the video output from the communication apparatus 100 to the monitor 301 via the HDMI interface 107. Thereby, the user wearing stereoscopic glasses can appreciate the video output to the monitor 301 as a stereoscopic video.

Next, the processing flow of the video conversion apparatus executed by the control LSI 101 will be described using the block diagram of FIG.
FIG. 3 is a block diagram showing details of the control LSI 101 in the first embodiment. Stream data (data passing through the transmission path) input from the camera / microphone 200 to the control LSI 101 is decoded by the decoder 1011 and converted into a baseband video signal. The baseband video signal output from the decoder 1011 is converted into a video signal obtained by inverting the left and right of the video by the reverse scanning unit 1012, and this video signal is output.
For example, as shown in FIG. 11, focusing on a video composed of one image, the reverse scanning unit 1012 has a function of inverting the left and right patterns. When the reverse scan unit 1012 reads out the frame video recorded in the memory unit from the memory unit, the reverse scan unit 1012 reads the video in a direction opposite to the direction recorded in the memory unit, thereby inverting the video. For example, in the left diagram of FIG. 11, when the video is addressed to the memory means from the left side to the right side, the reverse scanning unit 1012 moves the video recorded in the memory means from the right side to the left side of the left diagram of FIG. Invert the video by reading from the memory means in the direction.

The output video of the reverse scan unit 1012 is input to the frame delay conversion unit 1013. The frame delay conversion unit 1013 is means for adding a delay to the transmitted video frame. The scaler 1014 is a means for changing the size of an image.
In the present embodiment, for example, as shown in FIG. 5, the video of the other party received from the network is displayed on the display device 300. On the other hand, the self-portrait photographed by the camera / microphone 200 is reduced and synthesized with the partner's image at the lower right of the screen. As described above, in this embodiment, a conversation with the other party is realized while viewing the reduced self-viewed video.
The decoder 1015 converts the video stream received from the network into a baseband video signal by the decoder 1015. The video synthesis unit 1016 synthesizes the video signal whose size has been changed by the scaler 1014 and the video signal converted by the decoder 1015. In this way, the video signal output from the video synthesizing unit 1016 is a video signal obtained by synthesizing the partner video and the self video.

The output of the video composition unit 1016 is sent to the display device 300 via the HDMI interface 107 and displayed on the display device 300.
Next, the processing operation of the first embodiment will be described with reference to FIG. The decoder 1011 shown in FIG. 3 outputs a stereoscopically viewable video signal by a method called frame sequential. The stereoscopically viewable video signal is composed of a video frame (L) having a parallax for the left eye and a video frame (R) having a parallax for the right eye. The video frame (L) having the left-eye parallax and the video frame (R) having the right-eye parallax are alternately transmitted in time.
Here, among the video signals input from the decoder 1011 to the reverse scan unit 1012, a video frame having a parallax for the left eye is denoted as Ln (n = 0, 1,...) And has a parallax for the right eye. A video frame is denoted as Rn (n = 0, 1,...). The reverse scanning unit 1012 outputs the video signal by horizontally inverting it. In FIG. 4, the inversion notation of Ln and Rn indicates that the video is reversed left and right.

The frame delay conversion unit 1013 delays the video frame by one video frame. That is, the frame delay conversion unit 1013 outputs Ln output from the inverse scan unit 1012 as a left-eye video frame at the timing of the right-eye video. In addition, the frame delay conversion unit 1013 outputs Rn output as a video frame for the right eye from the inverse scanning unit 1012 at the timing of the video of the left eye.
The scaler 1014 changes the size of the video frame output from the frame delay conversion unit 1013.
On the other hand, a video frame having parallax for the left eye among video of the other party of the video phone received from the network or the like via the network interface 103 is denoted as L′ n (n = 0, 1,...) A video frame having parallax for the right eye is denoted as R′n (n = 0, 1,...).

In this case, the decoder 1015 decodes the input video of the other party of the videophone and outputs it as a baseband video signal. The video composition unit 1016 synthesizes and outputs the output of the scaler 1014 (own video) and the output of the decoder 1015 (partner video).
In this way, first, before the video composition unit 1016 synthesizes the own video and the partner video, the reverse scan unit 1012 mirrors the own video, and the frame delay conversion unit 1013 delays the own video. Next, the video composition unit 1016 synthesizes its own L0 and the partner R′0, and synthesizes its own R0 and the partner L′ 1. In other words, the mirrored video is synthesized with the other video in a state delayed by one frame.
The reason for this will be described with reference to FIG. The output video of the reverse scanning unit 1012 is to invert the left and right. However, as shown in FIG. 12, the output video of the reverse scanning unit 1012 is a video with parallax. For example, as shown in the upper part of FIG. 12, the L0 video has a depth of parallax on the left side as shown by an arrow A, as compared with a video without parallax indicated by a dotted line. In addition, the R0 video has a depth of parallax on the right side as indicated by an arrow B, as compared to a video without parallax indicated by a dotted line. In this case, as shown in the lower part of FIG. 12, the image reversed left and right by the reverse scanning unit 1012 has the opposite parallax direction as indicated by arrows A and B. In this way, simply reversing the video will reverse the depth information of the stereoscopic view.

Specifically, when the output video of the reverse scanning unit 1012 is displayed as it is, the 3D video that has jumped out to the near side is recognized as a 3D video that has been retracted to the back side, or conversely, the 3D video that has been retracted to the back side, Or it may be recognized as a 3D video that pops out toward you.
In order to solve this problem, in the first embodiment, a video frame that is mirrored using the inverse scanning unit 1012 is generated, and the previous mirrored video frame is generated using the frame delay conversion unit 1013. By setting it as the current video frame, it maintains the depth of its own video.
Also, the self video output from the frame delay conversion unit 1013 is enlarged and / or reduced by the scaler 1014, and is synthesized with the other video by the video synthesis unit 1016.
Through such a series of processing, as shown in the lowermost part of FIG. 4, the inverted self L0 video is synthesized with the partner's R'0 video, and the inverted self R0 video is the partner's L'1 video. And synthesized.

As a result, as shown in FIG. 5, even if the user's video is synthesized with the other's video, the user can stereoscopically view both videos without a sense of incongruity. Specifically, it is easier to predict the self-motion if the self-video is mirrored. In addition, it is easier to grasp the other party's operation if the other party's video is not mirrored. For this reason, in the first embodiment, the user can stereoscopically view the video as a video with no sense of incongruity.
(Embodiment 2)
Next, Embodiment 2 will be described with reference to FIG. FIG. 6 is a block diagram showing the operation of the control LSI 101 of the video composition apparatus in the second embodiment of the present invention.
The difference between the second embodiment and the first embodiment is the presence or absence of a depth detection unit 1017 and a depth correction unit 1018. For this reason, the description of the same configuration as in the first embodiment is omitted.

Since the video that has passed through the decoder 1011, the reverse scan unit 1012, the frame delay conversion unit 1013, and the scaler 1014 has parallax in the left and right video, in the second embodiment, the parallax is detected by the depth detection unit 1017.
The depth detection unit 1017 detects information related to parallax (parallax information) based on the configuration of the camera. For example, the parallax information is detected based on the focus position, tilt, and the like of a stereoscopic camera such as a binocular camera at the time of shooting. The disparity information is recognized by the communication apparatus 100, and is transmitted from the communication apparatus 100 to the outside along with the video stream. Then, this disparity information is acquired and used in a receiving device (a partner device).
On the other hand, the depth detection unit 1017 can also set the parallax information based on the video. For example, the parallax information is detected based on the shift amount with respect to the left and right videos. In this case, the parallax information is detected based on the shift amount in the self video. For example, in the self image, the depth is detected by recognizing a human face in the image and detecting the parallax thereof.

Here, an example in which the depth detection unit 1017 sets the parallax information based on its own video is shown, but the parallax information is set based on the other party's video in the same manner as described above. It may be.
The depth correction unit 1018 corrects the depth of its own video, and can add parallax by shifting the object in the left and right video in the horizontal direction.
Here, based on a signal input to the communication apparatus 100 from the input unit, for example, the remote controller 400, the parallax depth of the partner's video with respect to the parallax depth of the self video is set. For example, when the user operates the remote controller 400, the depth of parallax is set to a predetermined pattern. Here, three patterns from the first to the third are prepared. The first pattern is a pattern in which the parallax depth of the partner video is deeper than the parallax depth of the self video. The second pattern is a pattern in which the parallax depth of the partner video is shallower than the parallax depth of the self video. The third pattern is a pattern in which the depth of the parallax of the partner's video is substantially the same as the depth of the parallax of the own video.

For example, when the parallax depth of the self image is shallower than the parallax depth of the partner image (in the case of the first pattern), the partner image appears farther than the self image. The partner's figure can be displayed with a more three-dimensional effect. Further, when the depth of the parallax of the self video is deeper than the depth of the parallax of the other video (in the case of the second pattern), since the self video does not get in the way, for example, concentrate on the conversation. It becomes possible. Furthermore, when the parallax depth of the self video and the parallax depth of the other video are almost the same (in the case of the third pattern), it seems that the self video is blended in the other video. Therefore, it is possible to feel a sense of unity between the other party and the self with respect to the video.
In addition, from the form (second pattern) in which the other party's video is displayed so that the user's own video can be seen farther than the other party's video, the other party's video The form (first pattern) for displaying the image can make the user feel the expanse of the space. For this reason, in the first pattern described above, this matter is expressed by the word “three-dimensional effect”.

By using the video synthesized by the video synthesis unit 1016 in this way, the three-dimensional position of the own video can be adjusted with respect to the other video, as shown in FIGS. 5, 7, and 9. . Thereby, the self image can be set at an appropriate depth position with respect to the image of the other party.
(Embodiment 3)
Next, Embodiment 3 will be described with reference to the drawings. The difference between the third embodiment and the second embodiment is the presence or absence of the reverse scan unit 1019 and the frame delay conversion unit 1020. For this reason, the description of the same configuration as that of the second embodiment is omitted.
In FIG. 8, a decoder 1015 converts a video signal received from a network into a baseband video signal. The reverse scanning unit 1019 converts the baseband video signal into a video signal obtained by reversing the left and right sides of the video. The reverse scan unit 1019 functions in the same manner as the reverse scan unit 1012 described above.

The frame delay conversion unit 1020 delays the video frame. The frame delay conversion unit 1020 functions in the same manner as the frame delay conversion unit 1013 described above.
When the video is displayed on the display device 300, the communication device 100 notifies the display device 300 on a frame-by-frame basis which video is being sent via the HDMI interface 107. This is because in this embodiment, frame sequential is used.
The notification of the left and right video shown here is determined by the decoding result of the other video. This notification is updated in a frame cycle. The frame delay conversion unit 1020 delays the video that has been horizontally reversed by the reverse scanning unit 1019 by one frame. By synthesizing such a partner's image and the above-described self image, both the partner's image and the self image are displayed as a mirror image. That is, as shown in FIG. 9, the video can be displayed in a state where the self video is copied in the video of the other party.

Further, by detecting the depth of the self image and adjusting the depth of the self image (see the above-described patterns 1 to 3), the image can be blended in three dimensions with various patterns. Further, as described above, the images are mirrored together and displayed in a manner superimposed on the other's image, so that the composition of the photograph can be easily determined as if looking at the mirror.
As mentioned above, for example, when the depth of field of view of the other party's image is almost the same as the depth of parallax of the person's own image, the self's image appears to be blended in the other's image. You can feel a sense of unity with the other party. Thereby, it is possible to generate a composite photograph of the other party and the self as if taking a commemorative photo.
For example, by adjusting the parallax depth of the video with the remote control 400 or adjusting the position of the other party or one's own position, the adjusted video is made into a still image by operating the remote control 400, You can take a commemorative photo.

As a method of blending your own video into the other party's video, make your own video transparent when you place it at a depth greater than the predetermined parallax depth of your video, Can be stacked. Alternatively, a curtain or the like may be actually arranged on the back of the player, and the color and brightness of the curtain may be adjusted in the communication device 100 to make the surroundings transparent and overlap with the image of the other party.
When everyone who uses the video conversion system wants to take a commemorative photo, when trying to determine the composition of the still image (the composition of the photograph), it is better that everyone is mirrored and displayed on each person's monitor Easy to predict the operation. That is, in the third embodiment, since all the members are displayed as mirror images on each person's monitor, the operability when determining the composition can be improved. When the composition is determined, the still image can be obtained by storing the moment in a memory like a camera shutter using the remote controller 400.

In the third embodiment, an example in which there are two subjects has been described. However, the number of subjects is not limited to the above-described embodiment, and any number of subjects may be used as long as the number is two or more. In this case, the same effect as described above can be obtained.
The video whose composition has been determined as described above can be made into a commemorative photo by making it a still image. In addition, the still image created in this way can be easily created as a two-dimensional commemorative photo by converting from 3D to 2D.
Note that the other party's video received from a network or the like may be combined with an enlargement and / or reduction by providing a scaler function such as the scaler 1014.
In the above embodiment, the camera / microphone 200 has the encoder 203 and is encoded and input to the communication apparatus 100 as a stream. However, the camera / microphone 200 does not necessarily have an encoding function. It does not have to be. In this case, a baseband video signal is transmitted from the camera / microphone 200 to the communication apparatus 100. In the control LSI 101, since it is not necessary to decode the baseband video signal, a decoder is unnecessary. Therefore, the control LSI 101 executes the various processes described above based on the baseband video signal. Note that an encoder used for transmitting a video signal to another device is prepared inside the communication device 100 excluding the control LSI 101. That is, the baseband video signal is encoded by the encoder and then transmitted to another device.

The communication device 100 is an example of a video conversion device.
In Embodiment 1-3, the description has been given using the frame sequential as an example of a stereoscopically viewable video signal transmitted between devices. However, the present invention is not limited to frame sequential, and can be applied to other types of video signals that can be viewed stereoscopically. Other methods include side-by-side, top-and-bottom, checker pattern, and line-by-line.
For example, an example in which the method of stream data input from a 3D camera is side-by-side will be described. The decoder 1011 decodes the side-by-side baseband video signal, and then reverses the video by the reverse scanning unit 1012. When a side-by-side signal is input to the decoder 1011, the frame delay conversion unit 1013 does not perform time delay, but reverses the left-eye and right-eye images. Can be applied. Subsequent operations are the same as those disclosed in Embodiment 1-3.

Similarly, the stereoscopically viewable video signal received by the decoder 1015 may be of a different system from the frame sequential.

The present invention can be applied to a video conversion device. For example, the present invention can be applied to a BD recorder, a BD player, and the like.
