2. Description of the Related Art FIG. 5 is a diagram showing an imaging range at the time of imaging with a two-lens stereoscopic imaging apparatus used for obtaining a stereoscopic image.
FIG. 6 is a diagram showing an image obtained by this device. The two-lens stereoscopic imaging apparatus includes a left-eye imaging unit L and a right-eye imaging unit R separated by a reference distance set in accordance with the distance between the human eyes.
Are arranged, and the image corresponding to the parallax generated when the subject is seen by the human eye is obtained by the left-eye imaging unit L and the right-eye imaging unit R, respectively. In FIG. 5, the visual field range of the left-eye imaging unit L is a range between the straight lines L1 and L2, and the visual field range of the right-eye imaging unit R is a range between the straight lines R1 and R2. These imaging units L and R are composed of a lens system, CC
An image sensor such as D and a processing circuit for a signal output from the image sensor.

In the image pickup units L and R, light incident on an opening having a predetermined diameter indicated by a thick line in the drawing forms an image. Images obtained by these image pickup units L and R are respectively processed by a signal processing circuit in an NTSC system. And the like, and a stereoscopic image is displayed. As a form of the stereoscopic image display, a configuration in which two projectors are used to project the images on a screen in different polarization directions and observe the images using polarized glasses, or the imaging units L and R

In FIG. 5, an object whose imaging position is closer to the image pickup units L and R is indicated by X, and an object farther than the object X is indicated by O, the image for the left eye is indicated by the position shown in FIG. The image for the right eye is captured at the position shown in FIG. In other words, a nearby object is displayed at a position closer to the right on the display surface in the image for the left eye and closer to the left in the image for the right eye. FIG. 6C is a diagram illustrating how the left-eye image and the right-eye image are viewed when they are displayed in a superimposed manner.

In these figures, the images described by solid lines represent right-eye images, and the images described by broken lines represent left-eye images. Now, the close image X appears to have an image at the position indicated by the point a in the figure by making both eyes large "close", and the distant image ○ has the image at the point b in the figure. The image can give a stereoscopic effect to the image. That is, the image X whose imaging position is close to the imaging units L and R appears to jump out from the display surface (for example, the screen of the display or the projector) to the front side. However, for an object at a far distance, the rays from the object can be regarded as almost parallel rays, so that even if the left-eye image and the right-eye image are superimposed, they will be displayed on the same position, Looks like it is located at

[0006]

Therefore, when an image picked up by the above configuration is stereoscopically displayed by the above configuration, the entire image can be seen only on the side protruding from the display surface. Observation has a problem that both eyes of the observer remain crossed, resulting in a feeling of fatigue. Further, in order to obtain the right-eye image and the left-eye image having the predetermined parallax, it is necessary to use the above-described special two-lens stereoscopic imaging apparatus at the time of shooting.

[0007] The present invention has been made in view of the above-mentioned problems, and can display not only a stereoscopic image but also a planar image in a stereoscopic manner. In particular, it is an object of the present invention to provide a stereoscopic video apparatus and method capable of obtaining an image extending in the depth direction of the display surface and reducing an observer's feeling of fatigue by being able to perform stereoscopic display by combining images.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a stereoscopic video apparatus according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing a first embodiment of the device. The device is provided with a first video signal input terminal 1 to which a first video signal is input, and a second video input terminal 2 to which a second video signal is input. The first video signal and the second video signal are separated into two systems for the right eye and the left eye, respectively. The first video signal is provided by the first delay means 3, and the second video signal is provided by the second system. After a predetermined delay process is performed by each of the second delay means 4, the first video signal and the second video signal are superimposed by the superimposing means 5 for each system and supplied to the switching means 6. The switching unit 6 switches the image signal of each system at predetermined intervals and outputs the image signal to the display unit 7.

As the first video signal and the second video signal, different images are used (details will be described later), and they are finally synthesized and output as a three-dimensional image. And a normal plane image is input. The first video signal and the second video signal are frame-synchronized. However, when the video signals are not synchronized with each other, a synchronization such as a commonly used frame synchronizer is used. It is assumed that video signals synchronized with each other using a circuit are used.

The first video signal input from the first video signal input terminal 1 is divided into two systems for right eye and left eye, and a right eye delay circuit 3a and a left eye And input to the delay circuit 3b. The right-eye delay circuit 3a performs one horizontal scanning period (= 1H) + Δ1 on the basis of the scanning period of the video signal for the image of the first video signal.
Output with only a delay. On the other hand, the left-eye delay circuit 3b
One horizontal scanning period (= 1H) of the image of the first video signal
The output is delayed by Δ1. Here, 1H is a scanning period of one horizontal scanning line, and Δ1 has a positive delay amount of one to several μsec (for example, 2 μsec) based on the one horizontal scanning period, and Based on the video, the video signal moves forward and backward in the scanning direction by ± Δ1.

With respect to the right-eye image, the effect of shifting the image horizontally on the screen to the right by a certain amount can be obtained by the delay processing of 1H + Δ1. On the other hand, the image for the left eye is 1H
The effect of shifting the image horizontally on the screen by a certain amount to the left by the delay processing of -Δ1 is obtained. As described above, the delay amount represented by Δ1 is equal to the positive side (+ Δ) with respect to one horizontal scanning line scanned from left to right on the screen with respect to the scanning direction.
In 1) and the negative direction (-Δ1), the localization position of the image is shifted in the horizontal opposite direction.

Each of the delay circuits 3a and 3b has a line memory therein, temporarily stores a digital video signal for two horizontal scanning lines, and delays the input horizontal scanning line by 1H ± Δ1. And output. More specifically, the delay amount ± 1 is set from the bit data string constituting the video signal of one horizontal scanning line written in one line memory.
The bit part corresponding to Δ1 is read out and output. The video signal of the next (second line) one horizontal scanning line input during the one-line delay processing (during read-out) is temporarily stored in the other line memory. As described above, the delay processing for shifting the horizontal direction for a plurality of lines corresponding to the entire image by using the line memories for two lines alternately is repeatedly executed.

In the delay processing of 1H ± ΔH, the clock frequency may be slightly shifted from the frequency giving the delay amount by using the 1H delay line by the CCD image sensor.

Due to the delay processing of 1H ± Δ1, the entire image is shifted downward by 1H (for one horizontal scanning line) when viewed strictly. However, since one horizontal scanning line is a very small shift compared to the total number of horizontal scanning lines, it can be considered that there is no visual effect on the display. In order to strictly correct the shift of one horizontal scanning line, the synchronization signal may be shifted correspondingly by 1H (one horizontal scanning line).

On the other hand, the second video signal input from the second video signal input terminal 2 is separated into two systems for the right eye and the left eye, and the right eye delay circuit 4 constituting the second delay means 4
a and the left-eye delay circuit 4b. The right-eye delay circuit 4a performs one horizontal scanning period (= 1H) + on the image of the second video signal with reference to the scanning period of the video signal.
The output is delayed by Δ2. On the other hand, the left-eye delay circuit 4b
Represents an image of the second video signal for one horizontal scanning period (= 1
H) Output with a delay of -Δ2. Here, the delay amount Δ2
Is set to a positive (for example, 2 μsec), negative, or a delay value of 0. Here, when Δ2 is set to a positive delay amount, 1H +
The image is horizontally shifted rightward on the screen by the delay processing of Δ2 Δ
The effect of shifting by two equivalents is obtained. Similarly, the left-eye image can be horizontally shifted leftward on the screen by an amount corresponding to Δ2 by the 1H-Δ2 delay processing. On the other hand, when the delay amount Δ2 is 0, no image shift occurs on the screen. Further, when the delay amount Δ2 is a negative value,
The operation opposite to the case where the delay amount Δ2 is a positive value is obtained. For the image for the right eye, the image is horizontally shifted leftward on the screen by an amount corresponding to Δ2 by the delay processing of 1H + (− Δ2). become. Similarly, the image for the left eye is 1H-(-Δ
The image is horizontally shifted rightward on the screen by the delay processing of 2) Δ
It will be shifted by 2 equivalents.

The first video signal and the second video signal after the delay processing are combined by the superimposing means 5 for each of the right-eye and left-eye systems. The right-eye video signal of the first and second video signals is synthesized by the right-eye superimposing circuit 5a. Further, the left-eye video signal of the first and second video signals is synthesized by the left-eye superimposing circuit 5b. A general method such as chroma key is used for the image synthesizing process in the superimposing means 5. An example of combining images will be described later.

The right-eye image and the left-eye image that have been synthesized by the superimposing means 5 are alternately switched for each field by the switching means 6 and output to the display means 7. At the time of this switching, a field switching signal is output. The display means 7 is NTS
It is composed of a display such as a television having a display surface for displaying an image signal in the C system or the like, and switches between a right-eye image and a left-eye image for each of the fields and alternately displays them.

The glasses 8 for stereoscopic observation are provided with, for example, liquid crystal shutters for the right eye and the left eye, respectively, and transmit the light by switching the optical rotation of the liquid crystal for each field based on an input field switching signal. It has a configuration. Thereby, when the image for the right eye is displayed on the display means 7, the shutter for the right eye is opened, and the image for the right eye is recognized by the right eye. When the image for the left eye is displayed on the display means 7, the shutter for the left eye is opened. The left-eye image is recognized by the left eye, and a stereoscopic image can be observed.

FIG. 2 is a diagram showing a stereoscopic image displayed on the display means 7 of the device. It is assumed that the first video signal is an image of a landscape (mountains and trees) in the figure, and the second video signal is an image of a dashboard of a car. The superimposing means 5 includes a second
The scene portion included in the first video signal is combined with the image portion excluding the dashboard portion included in the video signal. The landscape image of the first video signal is displayed by the delay processing (delay amount ± Δ1) by the first delay means 3 so as to have a three-dimensional effect that extends deeper than the display surface of the display means 7. That is, due to the delay processing (1H ± Δ1) in the first delay unit 3, the right-eye image is delayed by + Δ1 and shifted rightward on the screen, while the left-eye image is delayed by −Δ1. As a result, the two images are shifted to the left on the screen, and are separated from each other by a distance twice as large as Δ1 compared to before the delay.

As a result, among the displayed images, the far distant mountains and trees constituting the first video signal are 2 · (Δ1) when the right-eye image and the left-eye image are superimposed.
, And the entire scene of the first video signal can be observed as a stereoscopic image that is recessed in the depth direction from the display surface of the display unit 7. Here, the human eye can make a so-called "cross-eyed" in which the left and right eyes are directed toward each other, but cannot direct the left and right eyes toward the outside where they diverge from each other. For this reason, if the value of 2 · (Δ1) is too large, the left and right images become invisible as a three-dimensional image. It is desirable to select a value of 2 · (Δ1) such that the line of sight of the left and right eyes when the left and right eyes do not go outside the parallel. That is,
According to the value of 2 · (Δ1), the value of the delay amount ± Δ1 in the first delay means 3 is determined. Then, when the observer is looking at the scenery based on the first video signal, the degree of “crossed eyes” can be reduced, so that the fatigue of the observer can be reduced.

On the other hand, by setting the delay amount Δ2 of the second delay means 4 to a positive value, for example, to a value smaller than the delay amount Δ1 of the first delay means 3 (Δ2 <Δ1), the second video signal The dashboard, which is an image of (1), appears to be slightly recessed from the display surface of the display means 7, and a landscape, which is the image of the first video signal, can be seen behind. Further, the delay processing (1H + Δ2) in the second delay means 4
Is set to zero (0), the second delay means 4 does not execute the delay processing on the second video signal. As a result, the dashboard of the car constituting the second video signal is located on the display surface of the display means 7 and appears behind the dashboard, which is the image of the first video signal (see FIG. 2).

The delay amount Δ in the second delay means 4
If 2 is set to a negative value, the entire second video signal appears to jump out of the display surface of the display means 7 toward the near side.
That is, the delay processing (1H ± Δ) in the second delay means 4
According to 2), the image for the right eye is delayed by -Δ2 and is shifted leftward on the screen, while the image for the left eye is + Δ
The image is delayed by two and shifted rightward on the screen, so that the image is displayed with a three-dimensional effect that jumps out of the display surface of the display means 7.

As described above, based on the value of the delay amount Δ2 set in the second delay unit 4, the image of the second video signal is obtained by moving the entire image forward, rearward, and rearward with respect to the display surface of the display unit 7.
Alternatively, it can be positioned on the display surface. As described above, the delay amount of the first video signal and the delay amount of the second video signal are made different from each other, and the first and second video signals are synthesized and displayed. It becomes possible to observe a stereoscopic image localized in different positions in the front-back direction.

The display image obtained in this way looks like an outside scene from the inside of the car through the windshield, and the scene (first image signal) and the dashboard (second image) are displayed.
Video signal) was created by combining images that were not individually shot as stereoscopic images,
You will be able to observe realistic images with a three-dimensional effect. By the way, the second video signal is not limited to the dashboard of an automobile, but may be a cockpit of an airplane or a window of a train, and of course, the first video signal may correspond to a scene corresponding to the second video signal. Can be used.

The first and second delay means 3 and 4 are configured to set the delay amounts. +-.. DELTA.1 and. +-.. DELTA.2 for one horizontal scanning line. However, the delay amounts are set in units of one field or one frame. A configuration for performing delay processing may be adopted. However, in any case, there is no change in the values of Δ1 and Δ2. In the case of delay processing in units of one field, a field memory for two fields is provided internally, in which video signals of odd fields are delayed in one field memory, and image data of even fields are stored in the other field memory. Temporarily store and use. Similarly, when delay processing is performed in units of one frame, a frame memory for two frames is internally provided, of which the first frame is delayed in one frame memory, and the frame memory for another frame is stored in the frame memory for another frame. Temporarily store and use image data.

Next, a second embodiment of the present invention will be described with reference to FIG.

The first video signal input from the first video signal input terminal 1 is supplied to the first delay means 3 by a predetermined delay amount Δ
1 and the second video signal input from the second video signal input terminal 2 is delayed by the second delay means 4 based on a predetermined delay amount Δ2.

The first and second delay means 3 and 4 switch and output delay processing for the right eye and delay processing for the left eye in field units based on the input field switching signal. Explaining a specific processing example, the first delay unit 3 executes the delay processing (1H + Δ1 described above) using the image of the first field (odd field) input as the first video signal for the right eye. Subsequently, delay processing (1H-Δ1) is performed using the image of the second field (even field) for the left eye. Similarly to the above, the second delay means 4 also applies (1H +
(2) and (1H-Δ2) are switched and executed.

According to the above configuration, there is no need to provide a delay circuit in each of the two systems for the right eye and the left eye, and the configuration can be simplified. In this embodiment, since the first and second delay means 3 and 4 switch between the right-eye image and the left-eye image in field units, the display means 7 displays the right-eye image in the same field unit. And the left-eye image are switched and displayed, and the stereoscopic observation glasses 8 are also configured to switch the right-eye shutter and the left-eye shutter in field units.

Next, a third embodiment of the present invention will be described with reference to FIG.

In the above embodiment, the first and second input
Although the configuration using a normal planar image as the video signal has been described, the first and second video signals may be those captured for stereoscopic video. The signal for stereoscopic video is
For example, an image is captured by a binocular stereoscopic imaging device. In the binocular stereoscopic imaging device, both right-eye and left-eye imaging units are arranged at a reference interval set in accordance with the distance between human eyes. The images picked up by these two image pick-up sections can obtain an image corresponding to the parallax generated when the subject is seen by human eyes. The first video signal input terminal 1 corresponds to the right-eye input terminal 1 and the left-eye input terminal 1
a and 1b, and are connected to the right-eye delay circuit 3a and the left-eye delay circuit 3b of the first delay means 3, respectively. The second video signal input terminal 2 has right-eye and left-eye input terminals 2a and 2b.
Are connected to the right-eye delay circuit 4a and the left-eye delay circuit 4b.

For example, when the localization position of the entire first video signal is to be retracted to a position deeper than the display surface of the display means 7, the right-eye delay circuit 3a performs the right-eye delay circuit 3a similarly to the above-described embodiment. The image is subjected to (1H + Δ1) delay processing, and the left-eye delay circuit 3b performs (1H−Δ1) delay processing on the left-eye image. On the other hand, when the localization position of the entire second video signal is to be protruded forward from the display surface of the display means 7, the right-eye delay circuit 4 a determines the right-eye image with respect to the right-eye image as described in the above embodiment. (1H-
Δ2) may be performed, and the left-eye delay circuit 4b may perform (1H + Δ2) delay processing on the left-eye image.

As described above, even for a video signal having a stereoscopic video as an original image (source), the stereoscopic video of the first and second video signals can be obtained simply by setting a predetermined delay amount in both delay means 3 and 4. The entire image can be relocated to desired front and rear positions with respect to the display surface. In the above description, an example has been described in which both the first and second video signals are stereoscopic video, but only one of them may be a stereoscopic video.

In the configuration described in each of the above embodiments, all the signal processing including the delay processing in the first and second delay means 3 and 4 until output to the display means 7 is digitized, and the switching means After the D / A conversion at 6, the signal may be converted into a signal form that can be displayed and output on the display means 7 such as the NTSC system.

Further, in the above-described embodiment, a configuration example in which a television display is used as the display means 7 and observation is performed with the stereoscopic observation glasses 8 has been described.
A configuration in which two projectors are used as the display means 7 and projection is performed on screens in different polarization directions, and the stereoscopic observation glasses 8 are observed using polarization glasses having left and right polarization planes corresponding to the polarized light, respectively. In this configuration, the same operation and effect as those of the above embodiments can be obtained. Furthermore, if projection is performed using a wide special lens such as a lenticular lens, a stereoscopic image can be observed without using the stereoscopic observation glasses 8.

Further, the images of the first and second video signals may be either planar images or stereoscopic images as described above, and these images may be either moving images or still images. Further, the video signal to be combined is not limited to the first and second video signals, and may be a combination of three or more videos. A plurality of video signals that can be combined can also capture a computer graphics (CG) image that has been image-processed by a computer as an original image, and also allow three-dimensional display. As described above, the observation of the stereoscopic video is not limited to the configuration described in the above embodiment. According to the present invention, similarly, various video signals such as a planar image and a stereoscopic image are used as the input video signal. The above-described stereoscopic image can be obtained.

The above description of the embodiment is merely an example of the present invention. Therefore, it goes without saying that the present invention can be variously modified according to the design and the like even if it is not in this embodiment within a range not departing from the technical idea of the present invention.

[0042]

According to the stereoscopic video apparatus and method of the present invention, a video signal input as an original image is separated into a right-eye image and a left-eye image, and the right-eye image is separated by the first and second delay means. For the left image, the image is shifted to the right, and for the left eye image, the image is shifted to the left so that even if the original image is a planar image, it can be observed as a stereoscopic image. become. Then, after using two or more sets of this video signal and delaying them with different delay amounts,
By performing the synthesizing process, it is possible to obtain an image having a dynamic stereoscopic effect that jumps back and forth with respect to the display surface.

In particular, the observer observes the three-dimensional image projecting to the near side of the display surface with a crossed eye, but can obtain a three-dimensional effect of being retracted backward. Since the eyes can be released from the crossed eyes state, the fatigue of the observer can be reduced. Thereby, according to the present invention, it is possible to observe a stereoscopic image for a long time.

Further, as described in claims 3 and 7, the input video signal is not limited to a planar image, and may be a stereoscopic image having a predetermined parallax for the right eye and the left eye. On the other hand, the localization position of the image at the time of stereoscopic display can be changed based on the delay processing.
