The image processing device 7 includes a decoding circuit 27 and a conversion circuit 29.
The combined image signal DATALR output from the combining device 5 is input to the decoding circuit 27 of the image processing device 7. The decoding circuit 27 separates the right image signal DATAAR and the left image signal DATAL from the composite image signal DATALR. Then, the decoding circuit 27 outputs the separated right image signal DATAAR and left image signal DATAL to the conversion circuit 29.
Note that the composite image signal DATALR includes 3D information including information regarding a stereoscopic image and a timing signal. The decoding circuit 27 also outputs 3D information to the conversion circuit 29.

The conversion circuit 29 generates a corrected image by correcting one of the right image signal DATAAR and the left image signal DATAL.

The surface 109 corresponds to the bottom surface of the image forming panel 63 opposite to the display surface 99. Therefore, hereinafter, the surface 109 is referred to as a bottom surface 109.

  The liquid crystal 105 is sandwiched between the element substrate 101 and the counter substrate 103, and is sealed between the element substrate 101 and the counter substrate 103 by a sealing material 107 that surrounds the display region 97 inside the periphery of the liquid crystal panel 91. Has been. In this embodiment, a VA (Vertical Alignment) type driving method is adopted as a driving method of the liquid crystal 105.

The retardation plate 93 is provided on the display surface 99 side, that is, on the opposite side of the liquid crystal 105 side from the counter substrate 103. In the image forming panel 63, the phase difference plate 92 and the phase difference plate 93 each give a phase difference of ¼ wavelength to the incident light.

The polarizing plate 94 a is provided on the bottom surface 109 side of the element substrate 101. The polarizing plate 94 b is provided on the display surface 99 side of the phase difference plate 93. Each of the polarizing plates 94a and 94b can transmit linearly polarized light having a polarization axis along the transmission axis. The transmission axis of the polarizing plate 94a and the transmission axis of the polarizing plate 94b intersect (orthogonal) each other.
The liquid crystal panel 91 also includes a scanning line driving circuit 111 and a signal line driving circuit 113 as shown in FIG. 6 which is a block diagram showing the liquid crystal panel driving circuit 53 and the liquid crystal panel 91. . The liquid crystal panel drive circuit 53 and the liquid crystal panel 91 are each one of the components of the liquid crystal device 115.

In the present embodiment, as shown in FIG. 6, the liquid crystal panel 91 includes n (n is an integer of 1 or more) scanning lines T and m (m is an integer of 1 or more) signal lines S. have. In the following, when n scanning lines T are individually identified, the notation of scanning line T (i) is used. i is an integer of 1 or more and n or less. When m signal lines S are individually identified, the notation of signal line S (j) is used. j is an integer of 1 or more and m or less.
Each of the n scanning lines T is connected to the scanning line driving circuit 111, and extends in the X direction with a space therebetween in the Y direction.
Each of the m signal lines S is connected to the signal line driving circuit 113 and extends in the Y direction with a space between each other in the X direction.

The pixel 95 is set corresponding to each intersection of the plurality of signal lines S and the plurality of scanning lines T. Among the plurality of pixels 95, a plurality of pixels 95 arranged along the Y direction form one pixel column 121. A plurality of pixels 95 arranged in the X direction constitute one pixel row 122.
The scanning line T is provided for each pixel row 122. Therefore, one pixel row 122 corresponds to one scanning line T. Accordingly, in the liquid crystal panel 91 having n scanning lines T, there are n pixel rows 122. In the following, when n pixel rows 122 are individually identified, the notation of pixel row 122 (i) is used.
Further, the signal line S is provided for each pixel column 121. For this reason, one pixel column 121 corresponds to one signal line S. Therefore, in the liquid crystal panel 91 having m signal lines S, there are m pixel columns 121. In the following, when the m pixel columns 121 are individually identified, the notation of the pixel column 121 (j) is used.

In the liquid crystal panel 91, for each pixel 95, a TFT (Thin Film Transistor) element 131, a pixel electrode 133, and a counter electrode 135, which are one of switching elements, are provided.
The gate electrode of the TFT element 131 is electrically connected to the corresponding scanning line T. The source electrode of the TFT element 131 is electrically connected to the corresponding signal line S. The drain electrode of the TFT element 131 is electrically connected to the pixel electrode 133.
The counter electrode 135 is electrically connected between the plurality of pixels 95, and the common signal Vc is supplied from the liquid crystal panel driving circuit 53, and is held at a common potential among the plurality of pixels 95.
The liquid crystal 105 (FIG. 5) is interposed between the pixel electrode 133 and the counter electrode 135. The driving of the liquid crystal 105 can be controlled for each pixel 95 by a voltage (driving voltage) applied between the pixel electrode 133 and the counter electrode 135. Thereby, the light modulation state can be controlled for each pixel 95. For this reason, the image forming panel 63 can function as a light valve.

The liquid crystal panel driving circuit 53 outputs a scanning signal PLS to the scanning line driving circuit 111 and outputs image data data to the signal line driving circuit 113 based on the input image signal DATA. Further, the liquid crystal panel drive circuit 53 outputs a common signal Vc to the counter electrode 135.
The scanning line driving circuit 111 outputs a selection signal g (i) for each scanning line T (i) based on the scanning signal PLS. The scanning signal PLS is a signal that defines the timing for outputting the selection signal g (i).
The signal line driver circuit 113 outputs the image data data as the data signal d (j) for each signal line S (j) based on the input image data data.
Further, the liquid crystal panel drive circuit 53 outputs a common signal Vc to the counter electrode 135. Thereby, the counter electrode 135 is maintained at the potential of the common signal Vc (hereinafter referred to as a common potential).

As shown in FIG. 7, the liquid crystal panel drive circuit 53 includes a controller 141, a memory unit 143, and a D / A converter (hereinafter referred to as DAC) 145.
An image signal DATA is supplied to the controller 141.
The memory unit 143 temporarily stores the image signal DATA for one frame. The controller 141 reads out image data data in units of 122 pixel rows from the image signal DATA for one frame stored in the memory unit 143. The controller 141 outputs the read image data data as serial data to the signal line driver circuit 113 via the DAC 145.
Further, the controller 141 outputs the scanning signal PLS to the scanning line driving circuit 111.

Here, the image signal DATA includes a timing signal VSYNC that defines the start of one frame period F, as shown in FIG. The scanning signal PLS includes a timing signal VSYNC and a clock signal CLY. The clock signal CLY is generated by the controller 141 with the timing signal VSYNC as a reference.
As illustrated in FIG. 9, the scan line driver circuit 111 includes a shift register 147. The timing signal VSYNC and the clock signal CLY are input to the shift register 147.
From the shift register 147, selection signals g (1) to g (n) are output. The selection signal g (1) is supplied to the scanning line T (1) as shown in FIG. The selection signal g (2) is supplied to the scanning line T (2), and the selection signal g (n) is supplied to the scanning line T (n).

As shown in FIG. 10, the selection signal g (i) has a pulse width of a half cycle of the clock signal CLY.
The selection signal g (1) is based on the second change point of the clock signal CLY after the timing signal VSYNC falls, that is, based on the rise of the second pulse of the clock signal CLY after the start of one frame period F. It rises from Lo level to Hi level. Here, the change point indicates a time point when the pulse signal changes from the Lo level to the Hi level and a time point when the pulse signal changes from the Hi level to the Lo level.
The selection signal g (1) rising to the Hi level is selected by the shift register 147 shown in FIG. 9 in the order of selection signals g (2), g (3),..., G (n) for each change point of the clock signal CLY. It will be shifted.

A period from when the selection signal g (1) rises to the Hi level to when the selection signal g (n) falls to the Lo level corresponds to one vertical period. In this embodiment, one vertical period is set to be shorter than one frame period F.
Note that the period in which the first pulse of the clock signal CLY is maintained at the Hi level after the start of one frame period F is a period for transferring the image data data from the controller 141 to the signal line driver circuit 113. .

Incidentally, the image 151 defined by the image signal DATA has a configuration in which the right image and the left image are alternately arranged every one frame period F as shown in FIG. Each of the right image and the left image is supplied as a plurality of frame images 153 whose display is updated every frame period F. In the image signal DATA, frame data that is data defining each frame image 153 is modulated. In the image 151, a frame image 155 that is a frame image 153 of the right image and a frame image 157 that is a frame image 153 of the left image are alternately arranged.
On the other hand, in the image 161 defined by the right image signal DATAR output from the image providing device 3 (FIG. 1), a plurality of frame images 155 of the right image are continuously displayed as shown in FIG. Are lined up. Similarly, in the image 163 defined by the left image signal DATAL output from the image providing device 3, as shown in FIG. 12B, a plurality of frame images 157 of the left image are arranged side by side.

The image 161 and the image 163 are combined by the combining device 5 (FIG. 1) as a combined image 165 in which the frame images 155 and the frame images 157 are alternately arranged as shown in FIG.
The composite image 165 is input to the decoding circuit 27 of the image processing device 7 (FIG. 1) as a composite image signal DATALR. The decoding circuit 27 separates the image 167 shown in FIG. 12D and the image 169 shown in FIG.
Then, the image 167 and the image 169 are input to the conversion circuit 29 as the right image signal DATAR and the left image signal DATAL shown in FIG.
The conversion circuit 29 generates a corrected image by correcting the image 169 out of the input images 167 and 169, and generates the image 151 shown in FIG. 11 from the generated corrected image as a new left image. .

Here, as illustrated in FIG. 13, the conversion circuit 29 includes a frame memory 171, a motion estimation unit 173, a corrected image generation unit 175, and a data synthesis unit 177.
Further, the image processing apparatus 7 has an input terminal 181, an output terminal 183, an output terminal 185, an output terminal 187, and an output terminal 189.
The composite image signal DATALR is input to the decoding circuit 27 via the input terminal 181. In addition, the projector 9 shown in FIG. 1 outputs an image signal DATA through an output terminal 187. The 3D information is output to the glasses 11 and the projector 9 via the output terminal 189.

As described above, the image pickup by the image pickup device 23 and the image pickup by the image pickup device 25 are synchronized with each other. That is, the image pickup device 23 and the image pickup device 25 are synchronized with each other at the time (image pickup time) at which the optical image is captured as an electric signal. For this reason, the image 161 (FIG. 12A) and the image 163 (FIG. 12B) are synchronized with each other. The fact that the image 161 and the image 163 are synchronized with each other means that the frame image 155 and the frame image 157 correspond at the imaging time.
As shown in FIG. 14, the frame image 155a in the image 161 corresponds to the frame image 157a in the image 163 at the imaging time. Similarly, the frame image 155b corresponds to the frame image 157b, and the frame image 155c corresponds to the frame image 157c.

In the composite image 165, one of the frame image 155a and the frame image 157a is positioned earlier in time than the other. In the present embodiment, in the synthesized image 165, the frame image 155a and the frame image 157a are positioned earlier in time than the frame image 157a, as shown in FIG. However, the frame image 155a and the frame image 157a may be either earlier or later in time.
The image 167 (FIG. 12 (d)) and the image 169 (FIG. 12 (e)) separated by the decoding circuit 27 are converted into a right image signal DATAR and a left image signal DATAL, respectively, as shown in FIG. 29.

The path of the right image signal DATAR input to the conversion circuit 29 branches into a path output to the output terminal 183 via the conversion circuit 29 and a path input to the data synthesis unit 177 in the conversion circuit 29.
The path of the left image signal DATAL input to the conversion circuit 29 includes a path output to the output terminal 185 via the conversion circuit 29, a path input to the frame memory 171 and a path input to the motion estimation unit 173. Branch to.
Further, the path of 3D information input to the conversion circuit 29 branches into a path output to the output terminal 189 via the conversion circuit 29 and a path input to the data composition unit 177.

The frame memory 171 holds each frame data of the image 169 (FIG. 12E) that is the left image. As described above, one frame data corresponds to one frame image 157. Therefore, the frame image 157 is held in the frame memory 171 as frame data.
The frame data held in the frame memory 171 is updated every frame period F. Accordingly, in the image 169 held in the frame memory 171, the frame image 157 is updated every frame period F.
That is, in the frame memory 171, the frame image 157 of the image 169 is updated in the order of the frame images 157a, 157b, 157c, 157d, 157e,... As shown in FIG.

The motion estimation unit 173 calculates a motion vector 191 shown in FIG. Further, the corrected image generation unit 175 generates a corrected image 169 ′ illustrated in FIG.
As illustrated in FIG. 13, the motion estimation unit 173 reads the frame image 157 (FIG. 16) of the image 169 that is the left image from the frame memory 171.
The corrected image generation unit 175 also reads the frame image 157 (FIG. 16) of the image 169 from the frame memory 171.

When the motion estimation unit 173 and the corrected image generation unit 175 read the frame image 157, the frame image 157 in the frame memory 171 is updated to a new frame image 157. At this time, the new frame image 157 is input to the motion estimation unit 173.
The above flow will be described in an easy-to-understand manner, for example.
When the motion estimation unit 173 and the corrected image generation unit 175 read the frame image 157a shown in FIG. 16 from the frame memory 171, the frame image 157 in the frame memory 171 is updated to the frame image 157b. At this time, the frame image 157 b is input to the motion estimation unit 173.

When the frame image 157a is read and the frame image 157b is input, the motion estimation unit 173 calculates a motion vector 191ab as shown in FIG.
Then, the motion estimation unit 173 outputs the calculated motion vector 191ab to the corrected image generation unit 175 illustrated in FIG.
The corrected image generation unit 175 generates a corrected image 157′a shown in FIG. 16 by correcting the frame image 157a based on the input motion vector 191ab. The corrected image 157′a is located temporally between the frame image 157a and the frame image 157b. That is, the corrected image 157′a is corrected to a state that progresses in time from the state of the frame image 157a.
In the present embodiment, the corrected image 157′a is corrected to a state that is advanced from the state of the frame image 157a by a half period of one frame period F.

Similarly, the motion estimation unit 173 reads the frame image 157b, and calculates the motion vector 191bc when the frame image 157c is input. Then, the corrected image generation unit 175 generates a corrected image 157′b shown in FIG. 16 by correcting the frame image 157b based on the input motion vector 191bc. Thereafter, motion vectors 191 are calculated in the order of motion vectors 191cd, 191de,..., And corrected images 169 ′ are generated in the order of corrected images 157′c, 157′d,.
The corrected image 157′b is located between the frame image 157b and the frame image 157c in terms of time. Similarly, in terms of time, the corrected image 157′c is located between the frame image 157c and the frame image 157d, and the corrected image 157′d is located between the frame image 157d and the frame image 157e.

As shown in FIG. 17, the corrected image 169 ′ generated by the corrected image generation unit 175 is output to the data synthesis unit 177 shown in FIG. 13 as a corrected image signal DATAL ′.
As a result of the above-described correction, in the present embodiment, the right image 167 and the corrected image 169 ′ are shifted from each other by a period of F / 2 as shown in FIG. This can be regarded as a pseudo shift between the imaging time of the image 167 and the imaging time of the corrected image 169 ′.
In the present embodiment, the corrected image 157′a is advanced by a period of F / 2 from the frame image 155a of the image 167. This is a state in which the imaging time of the corrected image 169 ′ is later than the imaging time of the image 167 by a period of F / 2.

The data combining unit 177 illustrated in FIG. 13 combines the right image signal DATAAR and the corrected image signal DATAL ′ (FIG. 17) as one image signal DATA (FIG. 11).
Here, as shown in FIG. 18, the image 151 has a configuration in which a corrected image 157′a is interposed between the frame image 155a and the frame image 155b. That is, in the image 151, the frame image 155 of the image 167 and the corrected image 157 ′ of the corrected image 169 ′ are arranged in order from the earliest imaging time. Therefore, in the image 151, the corrected image 157′b is interposed between the frame image 155b and the frame image 155c.
Then, the data synthesis unit 177 outputs the synthesized image signal DATA to the output terminal 187 as shown in FIG.

As shown in FIG. 1, the projector 9 to which the image signal DATA is input via the output terminal 187 projects the image 151 shown in FIG. 18 onto the screen 33 on which the projection light 31 is projected. At this time, in the image 151, the frame image 155 for the right eye and the corrected image 157 ′ for the left eye appear alternately for each frame period F.
In the display system 1, the observer observes the image 151 projected on the screen 33 through the glasses 11. As described above, in the glasses 11, the open / close state of the shutter unit 35 and the shutter unit 37 is controlled based on the 3D information.

In the present embodiment, the shutter unit 35 is controlled to be in the open state when the projector 9 displays the frame image 155 for the right eye. At this time, the shutter unit 37 is controlled to be closed.
On the other hand, when the projector 9 displays the correction image 157 ′ for the left eye, the shutter unit 37 is controlled to be in the open state. At this time, the shutter unit 35 is controlled to be closed.
Thereby, the observer can visually recognize the frame image 155 for the right eye with the right eye and visually recognize the corrected image 157 ′ for the left eye with the left eye. As a result, the observer can observe the parallax image as a pseudo stereoscopic image.

By the way, in the display system 1, when an observer observes a parallax image, the timing for visually recognizing the right image with the right eye and the timing for visually recognizing the left image with the left eye are different from each other.
For this reason, for example, in the image displayed by the projector 9, when the right image and the left image are synchronized with each other, between the state of the right image visually recognized by the right eye and the state of the left image visually recognized by the left eye A time lag occurs.
On the other hand, in the present embodiment, by correcting the state of the left image visually recognized by the left eye, the time that is generated between the state of the right image visually recognized by the right eye and the state of the left image visually recognized by the left eye. The shift is kept low. Thereby, the uncomfortable feeling of the observer who observes the parallax image can be reduced. As a result, it is possible to easily improve the display quality in the display of the pseudo stereoscopic image.
In this embodiment, the conversion circuit 29 corresponds to the input unit, the data synthesis unit 177 corresponds to the output unit, and the output terminal 183 and the output terminal 185 keep the two image states input. It corresponds to an output terminal for outputting these two images as they are. In the present embodiment, the image forming panel 63 (FIG. 4) corresponds to the image display unit, and the liquid crystal panel drive circuit 53 (FIG. 7) and the conversion circuit 29 (FIG. 13) correspond to the display control unit.

In the present embodiment, the image processing apparatus 7 has an output terminal 183 and an output terminal 185 (FIG. 13). The right image signal DATAR (FIG. 12D) is output to the output terminal 183. The left image signal DATAL (FIG. 12E) is output to the output terminal 185.
For this reason, the structure which connects the input terminal part (not shown) of the projector 9 to the output terminal 183, and connects the input terminal part (not shown) of the new projector 9 to the output terminal 185 can also be employ | adopted.
In the display system 10 using two projectors 9, for example, as shown in FIG. 19, the right image signal DATAAR can be input to the projector 9R, and the left image signal DATAL can be input to the projector 9L.

In the display system 10, glasses 201 are used. In the display system 10, a pseudo stereoscopic image can be observed by observing the images projected by the projector 9 </ b> R and the projector 9 </ b> L through the glasses 201.
The glasses 201 include a polarizing plate 203 and a polarizing plate 205. Each of the polarizing plate 203 and the polarizing plate 205 can transmit linearly polarized light having a polarization axis along the transmission axis. The transmission axis of the polarizing plate 203 and the transmission axis of the polarizing plate 205 intersect each other.
In the display system 10, the directions of the polarization axes of the projection light 31R from the projector 9R and the projection light 31L from the projector 9L intersect each other.

  In the present embodiment, the directions of the polarization axes of the projection light 31R from the projector 9R and the projection light 31L from the projector 9L are orthogonal to each other. Further, the transmission axis of the polarizing plate 203 and the transmission axis of the polarizing plate 205 are orthogonal to each other. When the direction of the transmission axis of the polarizing plate 203 and the direction of the polarization axis of the projection light 31R are matched, the direction of the transmission axis of the polarizing plate 205 matches the direction of the polarization axis of the projection light 31L.

With the above configuration, the observer can visually recognize only the projection light 31R with the right eye and only the projection light 31L with the left eye among the projection light 31R and the projection light 31L. As a result, the observer can observe the parallax image as a pseudo stereoscopic image.
In the display system 10, the projector 9R displays the image 167 (FIG. 12D) that is the right image, and the projector 9L displays the image 169 that is the left image (FIG. 12E). The image 167 and the image 169 are synchronized with each other. Then, the projector 9R and the projector 9L display the image 167 and the image 169 in a synchronized state with each other.
For this reason, in the display system 10, a time lag hardly occurs between the state of the right image visually recognized by the right eye and the state of the left image visually recognized by the left eye.

As described above, the image processing apparatus 7 has the output terminal 183, the output terminal 185, and the output terminal 187. For this reason, the image processing apparatus 7 can be applied to both the display system 1 using one projector 9 and the display system 10 using two projectors 9.
In the display system 1, the image processing device 7 outputs a corrected image 169 ′ obtained by correcting the image 169 out of the image 167 that is the right image and the image 169 that is the left image to the projector 9 as the left image. For this reason, in the display system 1, the image processing apparatus 7 is used in a mode (correction mode) in which the corrected image 169 ′ is output to the projector 9 as a left image.

  On the other hand, in the display system 10, the image processing device 7 maintains the state of the image 161 and the image 163 input to the conversion circuit 29 for the image 167 that is the right image and the image 169 that is the left image, respectively. Output to the projector 9R and the projector 9L. That is, in the display system 10, the image processing device 7 outputs the right image and the left image to the projector 9 without correcting both the input right image and the left image. That is, in the display system 10, the image processing device 7 is used in a mode (non-correction mode) in which neither the right image nor the left image is corrected.

Thus, since the image processing apparatus 7 has the correction mode and the non-correction mode, the image processing apparatus 7 can be applied to both the display system 1 and the display system 10.
In the present embodiment, the output terminal 183, the output terminal 185, and the output terminal 187 of the image processing apparatus 7 are independent of each other. For this reason, in the present embodiment, the display system 1 and the display system 10 can be realized simultaneously by one image processing apparatus 7.
In the present embodiment, the output terminal 187 shown in FIG. 13 can be omitted by providing the image processing apparatus 7 with the switching circuit 211 shown in FIG. In the switching circuit 211, the output to the output terminal 183 can be switched between the image signal DATA and the left image signal DATAL by the switch 213. Thereby, the number of output terminals in the image processing apparatus 7 can be reduced.

In the present embodiment, the image processing device 7 and the projector 9 are exemplified as devices independent from each other. However, the configurations of the image processing device 7 and the projector 9 are not limited thereto. As configurations of the image processing device 7 and the projector 9, for example, a configuration in which the projector 9 includes the image processing device 7 may be employed.
In the present embodiment, the configuration in which the image providing device 3 includes the imaging device 21 is exemplified as the configuration of the image providing device 3, but the image providing device 3 is not limited to this. As the image providing device 3, for example, a DVD (Digital Versatile Disc) player or the like may be employed. In this case, a DVD in which the right image signal DATAR and the left image signal DATAL are recorded is used.

In the present embodiment, the image providing device 3 and the synthesizing device 5 are exemplified as devices independent from each other. However, the configurations of the image providing device 3 and the synthesizing device 5 are not limited thereto. As the configuration of the image providing device 3 and the composition device 5, for example, a configuration in which the image provision device 3 includes the composition device 5 may be employed.
In this embodiment, the synthesizing device 5 and the decoding circuit 27 are included. However, the synthesizing device 5 and the decoding circuit 27 are not necessarily indispensable configurations. If the right image signal DATAR and the left image signal DATAAL output independently from the image providing device 3 can be input to the conversion circuit 29 while maintaining the state of these signals, the synthesizing device 5 and the decoding circuit 27 are connected. Can be omitted.

In the present embodiment, an image forming panel 63 having a transmissive liquid crystal panel 91 is employed as the light valve. However, the liquid crystal panel 91 is not limited to the transmissive type, and a reflective type may be employed.
Further, the light valve is not limited to the liquid crystal panel 91, and for example, a mirror device in which a mirror element is arranged for each pixel 95 may be employed. In the mirror device, an image can be displayed by driving the mirror element for each pixel 95 and selectively controlling the light reflection direction in the plurality of pixels 95.
In this embodiment, the example in which the liquid crystal device 115 (FIG. 6) is applied to the projector 9 has been described. However, the application of the liquid crystal device 115 is not limited to the projector 9. The liquid crystal device 115 can be applied to a display device such as a display, for example.

In this embodiment, the VA type driving method is adopted as the driving method of the liquid crystal 105, but the driving method is not limited to this. As the driving method of the liquid crystal 105, various methods such as a TN (Twisted Nematic) type, an IPS (In Plane Switching) type, and an FFS (Fringe Field Switching) type can be adopted.
In addition, the electronic device to which the liquid crystal device 115 can be applied is not limited to the projector 9, but may be a mobile phone, a mobile computer, a digital still camera, a digital video camera, a car navigation system display device such as a car navigation system, an audio device, or the like. There are various electronic devices.
Further, electronic devices that can be used in the display system 1 and the display system 10 are not limited to the projector 9.
