Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 3D image software conversion method for converting 2D image software into 3D image software having parallax.

[0002]

2. Description of the Related Art Conventionally, in order to obtain a three-dimensional image having left and right parallax, a two-channel stereoscopic video signal (three-dimensional video signal) obtained by imaging with a dedicated stereoscopic imaging device is recorded by a stereoscopic VTR. , It was necessary to reproduce this and reproduce it on a dedicated three-dimensional display or the like.

Therefore, according to this method, the existing 2D video software cannot be used, and it is necessary to newly produce 3D video software, which causes an increase in the cost of the stereoscopic image reproducing system. .

On the other hand, there is a method of obtaining a stereoscopic effect even with light stimuli that are simultaneously lit, by utilizing the relationship between the perceptual time and the stimulus intensity where the brighter one feels as if it was lit earlier (the Pulfrich effect). That is, when there is an object that moves in the horizontal direction in a normal video signal (two-dimensional video signal), a stereoscopic effect occurs when observing the object with glasses having different transmissivities on the left and right.

[0005]

However, even the above method has a drawback that special glasses are required.
The present invention solves the above-mentioned drawbacks and converts existing 2D video software into pseudo 3D video software without the need for special glasses and without the production of 3D video software. The present invention provides a 3D image software conversion method capable of performing the above.

[0006]

The present invention is a three-dimensional video software conversion method which uses two-dimensional video software and creates three-dimensional video software having a right-eye video and a left-eye video from the two-dimensional video software.

Further, according to the present invention, the right-eye image and the left-eye image are selected by temporarily storing the two-dimensional image software in the memory and selecting the number of delay fields read from the memory according to the speed of the moving portion of the two-dimensional image software. Is a 3D image software conversion method for creating 3D image software having

Further, the present invention is based on two-dimensional video software,
In a three-dimensional video software conversion method for obtaining three-dimensional video software by generating a main video signal and a sub-video signal delayed with respect to the main video signal, in the field of the main video signal and / or the sub-video signal This is a three-dimensional video software conversion method in which interpolation processing or inter-field interpolation processing is performed.

[0009]

With the above-described means, parallax occurs in the two-dimensional video software due to the relative addition of the time difference or the luminance difference, and the two-dimensional video software is pseudo-converted into the right-eye video signal and the left-eye video signal. The time difference or the brightness difference is controlled according to the amount of movement of the two-dimensional video signal.

Further, by performing the intra-field interpolation processing on the main video signal and / or the sub video signal, there is no vertical shift between the image by the main video signal and the image by the sub video signal.

Further, the inter-field interpolation process is applied to the main video signal and / or the sub video signal to smoothen the movement of the three-dimensional image.

[0012]

First, the principle of the present invention will be described. Figure 1
In a video scene in which the background does not change and the subject moves from left to right as in A, when a certain time difference is provided between the reproduced right-eye video and left-eye video as shown in FIG. The position is different by the amount of the movement, and this results in parallax as shown in FIG. The numbers in FIGS. 1B and 1C represent field numbers.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram of a first embodiment of a 3D image software conversion system in which the 3D image software conversion method of the present invention is used, and is a 2D / 3D compatible VTR 11
The 2D video software reproduced in 3 is based on the method of the present invention.
The three-dimensional image software is converted into pseudo three-dimensional image software by the three-dimensional image software conversion device 12 and then supplied to the 3D monitor 13. If this 3D monitor is a lenticular type glasses-free display as described in Japanese Patent Laid-Open No. 3-65943, even if it is a two-dimensional video signal without glasses, there is a partial stereoscopic effect. A three-dimensional image can be simulated.

FIG. 3 is a schematic block diagram of the three-dimensional video software conversion device in FIG. 2, and a two-dimensional video signal is input to the input terminal 1. One of the two-dimensional video signals is supplied to the video switching circuit 2.

The other of the two-dimensional video signals is supplied to the field memory 5. The field memory 5 is variably controlled by the memory control circuit 6 on a field-by-field basis within a range from a delay amount of 0 to a maximum of 60 fields (about 1 second in the NTSC system). The variable unit may be a small unit of 1 field or less.

The field memory output is supplied to the video switching circuit 2. This video switching circuit 2
The outputs are connected to the output terminal 3 for outputting the left-eye video signal L and the output terminal 4 for outputting the right-eye video signal R, respectively, and are controlled so that the output state is switched according to the direction of movement of the subject.

The other of the two-dimensional video signal is supplied to the motion vector detection circuit 7, and after detecting a motion vector corresponding to the motion between fields, it is supplied to the CPU 8.
The CPU 8 extracts a horizontal component from the motion vector and controls the memory control circuit 6 in accordance with this. That is, when the motion of the subject is large and the motion vector is large, the delay amount of the field memory 5 is controlled to be small, and when the motion of the subject is small or the motion vector is small as in slow motion reproduction, the delay amount is reduced. Controlled to be more. Note that the maximum number of delay fields in the field memory is 60 fields, which corresponds to one second of the NTSC system and is a time that can correspond to a normal video scene, but when using for slower slow motion reproduction, A large capacity memory of 60 fields or more may be used. Also, the number 1 is required for ultra-slow slow-motion playback.
It may be delayed by 00 fields.

Further, the CPU 8 switches the two-dimensional video signal to the left-eye video signal when the direction of the motion vector is from left to right, and the delayed two-dimensional video signal to the left-eye video signal in the opposite case. Control 2

Therefore, in a scene in which a subject moves in the horizontal direction in a two-dimensional video signal, parallax corresponding to the speed of movement occurs. And these output terminals 3, 4
If the left and right video signals from the device are supplied to a lenticular type glasses-free display as described in Japanese Patent Laid-Open No. 3-65943, a stereoscopic image with a partial stereoscopic effect is pseudo even if it is a two-dimensional video signal. Can be reproduced.

Next, the above three-dimensional video software conversion device
An example in the case of SI conversion will be described with reference to FIG. The two-dimensional video signal is first separated into a luminance signal Y and color difference signals RY and BY by a YC separation circuit 30, and A / D converted by A / D conversion circuits 31 and 32. The A / D converted signal is input to the 2D / 3D conversion LSI 33.
The luminance signal Y input to the LSI 33 is clamped by the clamp circuit 331 and supplied to the motion vector detection circuit 7, the passage selector S1, the interpolation selector S2, and the external field memory 5. The field memory 5 includes MO1 to MO3 in which odd field data is written and ME1 to ME in which even field data is written.
The six field memories No. 3 and No. 3 are connected in parallel, and writing and reading are controlled by the memory control circuit 332.

The motion vector detected by the motion vector detecting circuit 7 is supplied to the CPU 8, which then controls the memory control circuit 332 based on the horizontal component of the motion vector.
To control.

On the other hand, the color difference signals R-Y and B-Y are clamped by the clamp circuit 333 and converted into a dot-sequential signal in which R-Y and B-Y alternately appear in the dot cycle. This color difference signal is supplied to the passage selector S3, the interpolation selector S4 and the field memory 5.

A total of 12 bits of 8 bits for the luminance signal and 4 bits for the color difference signal are supplied to each of the field memories. The respective luminance signal outputs YO of the field memories MO1 to MO3 and the respective luminance signal outputs YE of the field memories ME1 to ME3 become one and are inputted to the respective input terminals of the passage selector S1 and the interpolation selector S2. Further, the respective color difference signal outputs of the field memories ME1 to ME3 become one and are inputted to the respective input terminals of the passage selector S3 and the interpolation selector S4.

Next, the output of the interpolation selector S2 is supplied to the line memory LM1 and the interpolation circuit 334. The luminance signal delayed by 1H (H is a horizontal scanning period) in the line memory is input to the line / field selector S5 together with the luminance signals YO and YE. This selector S5
The output is supplied to the interpolation circuit 334. The interpolation circuit 334 is composed of two coefficient units and one adder for adding these outputs. The interpolation unit K is included in the coefficient unit on the selector S2 side and the coefficient unit included in the selector S5 is a ring. The interpolation factor (1-K) is multiplied. The output of the interpolation circuit 334 and the output of the passage selector S1 are supplied to the right output selector S6 and the left output selector S7, respectively. The outputs of the selectors S6 and S7 are the first and second parallax adjustment memories SM.
1, SM2 is supplied. The parallax adjustment memory allows the horizontal read position of the output image to be adjusted independently for the left and right by ± 48 pixels, and the sense of depth is adjusted by arbitrarily adjusting the parallax amount.

The color difference signal processing circuits after the passage selector S3 and the interpolation selector S4 are the same as the luminance signal, and the line memory LM2, the line / field selector S8, the interpolation circuit 334, the right output selector S9, and the left output selector. S10, third and fourth parallax adjustment memory SM3,
SM4 is arranged.

A sync signal is added to the outputs of the first to fourth parallax adjustment memories by a sync signal adding circuit 336 to become a right-eye luminance signal YR and a left-eye luminance signal YL, and the color difference signal is converted into a color signal by an encoding circuit 337. The signals are encoded into the right-eye color signal CR and the left-eye color signal CL, which are output from the LSI. Of these outputs, YR and CR are A / D converted by the D / A conversion circuit 34 and combined by the YC combination circuit 35 to form the luminance signal Y. Also, YL and CL are D / A
The color signal C is D / A converted by the conversion circuit 36 and combined by the YC combination circuit 37 to form the color signal C.

Next, the operation of the above-mentioned three-dimensional video software conversion device will be described with reference to FIGS. First, the operation of the field memory 5 will be described. As shown in FIG. 5, MO1 to ME3 are sequentially written in each field memory for each field by a write pulse from the memory control circuit 332, and after 6 fields, the writing is completed in all the field memories. In this state, the data from the first field to the sixth field are written in each field memory without duplication. Each field memory then stores the data content until a write pulse is input. Then, when the write pulse is supplied to MO1 in the 7th field, the data content is rewritten to that of the 7th feed. MO1 like this
Data of ME3 is cyclically rewritten at different timings for every 6 fields.

On the other hand, the read control is performed as follows. The memory control circuit 332 selects a field memory that stores data of necessary fields based on the number of delay fields determined by the CPU 8 according to the movement of the image, and outputs a read pulse. For example, when the delay field number is 2 fields and the current field is O3, the read pulse is supplied to MO2 in which the data O2 two fields before is stored, and the data O2 is MO2.
2 is read.

In this embodiment, since field memories are connected in parallel and writing is performed only to one of the six at the same time, the field memories are connected in series to write all the field memories in each field. Power consumption can be significantly reduced compared to the method of performing.

Next, the operation of each selector will be described for each mode. Although the following description is for the luminance signal processing circuit, the color difference signal processing circuit has exactly the same operation. Further, all the selectors perform the selection operation by the control signal from the CPU 8.

The video signal processing circuit including each selector basically has an intra-field interpolation mode and an inter-field interpolation mode, and these can be selected according to the magnitude of the motion vector. That is, each selector is controlled so that the intra-field interpolation mode is selected when the motion vector is smaller than the predetermined threshold value, and the inter-field interpolation mode is selected when the motion vector is large. When further editing is performed, the edit mode is selected.

The operation in each mode will be described below. (Intra-field interpolation mode) In this mode, there are a field in which interpolation is not performed and a field in which intra-field interpolation is performed. In other words, if one of the left and right screens is an odd field and the other is an even field, there will be a vertical shift between the left and right screens if reproduced as it is. The image interpolated in the vertical direction based on is used.
Interpolation is not required if both left and right screens are odd or even fields.

In this mode, the pass selector S1 always selects the luminance signal Y from the clamp circuit 331 and supplies the undelayed data to the left output selector S6 and the right output selector S7. On the other hand, the interpolation selector S
As shown in FIG. 5, 2 selects Y, YO, or YE according to the number of delay fields. Further, the field / line selector S5 always selects the line memory LM1 output.

Therefore, the interpolation circuit 334 receives the output of the interpolation selector S2 and the output delayed by 1H. The interpolation coefficient of the interpolation circuit 334 is set by the CPU 8. However, if the output of the interpolation selector S2 is an odd or even field with respect to the output of the selector S1, K = 1 and no interpolation is performed, and one of them is an odd number. If the other of the fields is an even field, K = 0.5 and intra-field interpolation is performed.

Therefore, the interpolated delay output is obtained at the output of the interpolation circuit 334, and this is the selector S6.
And S7. These two selectors constitute the video switching circuit 2 in FIG. 3, and select which of the left and right side the current field signal and the delayed signal are complementarily output depending on the direction of the motion vector.

Then, these outputs are supplied to the parallax adjustment memories SM1 and SM2, respectively, and the parallax amount is adjusted. (Inter-field interpolation mode) In this mode, there are a field in which no interpolation is performed, a field in which inter-field interpolation is performed, and a field in which inter-field interpolation is performed.

Interfield interpolation is applied to the field immediately after the number of delay fields has changed. That is, when the number of delay fields changes, the motion of the delay image becomes less smooth than the image of the current field, so the motion is smoothed by inter-field interpolation. In the other fields, the same operation as in the intra-field interpolation mode is performed.

Even in this mode, the passage selector S1
Always selects the output of the clamp circuit 331. On the other hand, the interpolation selector S2 selects Y, YO, or YE as shown in FIG. Further, the line / field selector S5 outputs YE, YO, line memory LM1 output LM.
Select one of Interpolation coefficient K of the interpolation circuit 334
Is K = 1 if both the outputs of the interpolation selector S2 and the output of the selector S1 are odd or even fields.
Will not be interpolated. K in all other fields
However, if one is an odd field and the other is an even field (E2, E4, E7, E9), inter-field interpolation is performed and the field (O2, O3, O4, O5, O7, O8,
In O9), inter-field interpolation is performed.

When intra-field interpolation is performed, the selector S2 selects Y0 and the selector S5 selects LM. Further, when inter-field interpolation is performed, the selectors S2 and S5 respectively select YO or YE except when the number of delay fields is converted from 0 to 1. That is, adjacent fields are selected and supplied to the interpolation circuit 334. Therefore, the output of the interpolation circuit is an average of both outputs, and the motion of the image is smoothed.

The operations of the selectors S6 and S7 are the same as the intra-field interpolation mode. (Editing Mode) In the above two modes, the outputs of the selectors S6 and S7 complementarily irregularly switch the original signal and the delayed signal depending on the direction of the motion vector. here,
When comparing the original signal and the non-delayed signal (for example, the current field of FIG. 5 and the output of the interpolation circuit), the delayed signal has a loss of the regularity of the field order in the time axis direction. In particular, a certain field is thinned out in the process of decreasing the number of delay fields. For this reason, the delay signal impairs the reproducibility of the original image. Therefore, regardless of which of the left and right outputs is selected, this delayed signal is mixed, and it is not preferable to use this output for editing.

That is, at the time of editing, at least one of the outputs must have a signal having the same field order as the original image. When operating the LSI of this embodiment in this edit mode, the output terminal of the field memory and the LS
It is necessary to provide an external selector between the I and memory input terminals, and it is desirable to increase the number of field memories to about 13 fields.

In this mode, the selectors S6 and S7 are fixed and the output of the pass selector S1 is always R output. The selector S1 is always fixed to the input YO, and the selector S2 is always fixed to the input YE. For the selector S1, the external selector selects a memory output from which a signal with a fixed delay field number is obtained and supplies it to the selector S1, and selects a memory output from which a signal with a variable delay field number according to the movement is obtained. And supplies it to the selector S2.

By doing this, when editing,
A signal having the same field order as the original image can always be obtained at one of the output terminals. Although the three-dimensional video software conversion device in the above-described embodiment is configured to generate a time difference between two-dimensional video signals as a method of adding left and right parallax, it may be configured to generate a luminance difference instead of the time difference. ,
Stereoscopic viewing is possible due to the Pulfrich effect.

FIG. 7 shows this embodiment. That is, in this embodiment, the field memory 5 and the memory control circuit 6 are replaced by the attenuator 9 and the gain control circuit 10 which attenuate the luminance level between 0 db and -10 db. This attenuator and gain control circuit is controlled based on the magnitude of the motion vector as in the embodiment of FIG.
That is, when the motion of the subject is large and the motion vector is large, the brightness attenuation amount of the attenuator 9 is controlled to be small, and when the motion of the subject is small or the motion vector is small as in the slow motion reproduction, the brightness attenuation amount is small. Is controlled to increase.

The attenuation amount of the attenuator is 0 to -10d.
Not limited to b, when used for slow-motion slow motion reproduction, an attenuation amount of −several tens of db may be given. A variable gain amplifier may be used instead of the attenuator.

Further, according to the present invention, even if the existing 2D image software is not converted into 3D image software, the 2D image signal output in real time from, for example, a video camera or a CG production device is converted into 3D in real time. It can also be applied when converting to a video signal.

On the other hand, the two-dimensional video signal from the input terminal 16 is converted into a three-dimensional video signal by the three-dimensional video software converter 12 to be a two-channel signal and supplied to the changeover switch S. The changeover switch S is automatically changed over according to the type of input signal. That is, the input three-dimensional video signals from the input terminals 14 and 15 are respectively input to the first video detection circuit 17 and the presence or absence of the video signal is detected, and then the logical product output of the detection outputs is supplied to the control circuit 19. .

Therefore, in this embodiment, it is automatically determined whether the input signal is a 2D video signal or a 3D video signal, and when the 3D video signal is input, the 2D video signal is input as it is. Converted to 3D video signal and then 3D
It is supplied to the monitor 13.

That is, in the 3D mode, the changeover switch S is switched to the side a by the "H" discrimination signal, and in the 2D mode, the power of the three-dimensional video software converter 12 is turned on by the "L" discrimination signal. Together with the changeover switch S
