Description

  The present invention relates to an image display apparatus and method.

  Conventionally, a plurality of images are displayed on a single screen, and only images belonging to the same content among these images are selectively reached by the viewer, so that the viewer can view the desired content image. There is a technique (see Patent Document 1).

  According to this technology, an image belonging to the same content in which the polarization direction is set to the vertical direction from one projector (an image of the appearance of an object in Patent Document 1) is projected on the screen, and the polarization direction is changed horizontally from the other projector. By projecting images on the screen (images of the internal structure of things in Patent Document 1) belonging to the same content in the direction and having viewers selectively wear polarized glasses with different polarization directions, The image of the desired content is visually recognized by the person.

According to such a technique, when two viewers wear polarized glasses having different polarization directions, it is possible to provide images of different contents to each viewer.
JP-A-4-321020

  However, in the technique of Patent Document 1, since contents are distributed according to the polarization direction of image light, only up to two contents can be displayed. When an image of more content than this is projected on the screen, the polarization direction of the polarized glasses can only be formed in the vertical direction or the horizontal direction, so that the viewer can arbitrarily select all the content. Practically impossible.

  Moreover, in the technique of Patent Document 1, when the viewer desires to view images of different contents, it is necessary to replace the polarized glasses. For this reason, it becomes necessary to prepare two polarizing glasses having different polarization directions for all the viewers, and the viewer's hand is bothered when changing the content.

  The present invention has been made in view of the above-described problems, and an object thereof is to easily provide an image of a plurality of contents to a viewer.

  In order to achieve the above object, the image display device of the present invention selectively displays only image light of an image belonging to a predetermined same content among the display means for displaying images belonging to different contents in a time division manner. It comprises selection means that is driven in a time division manner in synchronization with the display means so as to be transmitted, and synchronization means that synchronizes the display means and the selection means.

  The image display method of the present invention displays images belonging to different contents in a time-sharing manner, and transmits image light in synchronization with the timing at which images belonging to the same content desired by the viewer are displayed. To reach the viewer.

In such an image display apparatus and method of the present invention, images belonging to different contents are displayed in a time-sharing manner, and image light is transmitted in synchronization with the timing at which images belonging to the same content desired by the viewer are displayed. And reach the viewer.
For this reason, since only the image light of the images belonging to the same content reaches the viewer, the viewer visually recognizes that only the image of the same content is displayed on the display means. That is, according to the image display apparatus and method of the present invention, the viewer can easily view an image of any content by synchronizing the timing at which a desired image is displayed and the timing at which image light is transmitted. It becomes possible. Therefore, according to the image display apparatus and method of the present invention, it is possible to easily provide images of a plurality of contents to a viewer.
In the image display apparatus and method of the present invention, since images belonging to different contents are displayed in a time division manner, it is possible to display images of three or more contents. Since the image light is transmitted in synchronization with the timing at which the image of any content is displayed, it is possible for the viewer to visually recognize the image of different content without being mixed. Thus, it is possible to provide more images of content.

In the image display device of the present invention, the selection means can be switched so as to selectively transmit only the image light of an image belonging to another same content different from the predetermined same content among the images. The configuration can be adopted.
By adopting such a configuration, the content visually recognized by the viewer can be changed by a single selection means. Therefore, it is troublesome to change glasses when changing the content as in the prior art. There is no need to force the viewer to perform the work, and it is possible to more easily provide images of a plurality of contents to the viewer.

In the image display device of the present invention, the images belonging to the predetermined same content are parallax images, and the selection unit causes the image light of the right-eye image of the parallax images to reach only the right eye of the viewer. A configuration in which a right-eye transmission unit and a left-eye transmission unit that allows the image light of the left-eye image among the parallax images to reach only the left eye of the viewer can be employed.
By adopting such a configuration, the right-eye image of the parallax image is reached only to the viewer's right eye, and the left-eye image of the parallax image is reached only to the viewer's left eye. As a result, the viewer can view the stereoscopic image.
The right-eye image and the left-eye image are separately displayed in a time-division manner on the display means. These right-eye image and left-eye image both form one image (stereoscopic image). Therefore, in the present invention, the images belong to the same content.

In the image display apparatus of the present invention, specifically, a configuration in which the selection unit is a liquid crystal shutter can be employed.
The synchronizing means is disposed on the display means side and invisible light emitting means for emitting light that is not included in the visible region in accordance with an image displayed on the display means, and is disposed on the selection means side. A configuration in which a light receiving unit that outputs a synchronization signal that synchronizes the display unit and the selection unit according to a light receiving state of light can be employed.
Further, it is possible to adopt a configuration in which the display means is configured to include a projector and a screen.

The image display apparatus of the present invention further includes an audio output unit that outputs sound corresponding to the image light transmitted by the selection unit only to a viewer who reaches the image light transmitted by the selection unit. The configuration can be adopted.
By adopting such a configuration, it is possible to provide audio corresponding to the content without mixing different audio to the viewer even when the content includes audio. It becomes.

In the image display device of the present invention, a configuration in which the audio output unit and the selection unit are integrally formed as glasses can be employed.
By adopting such a configuration, it is possible to provide both the image and the sound to the viewer when the viewer wears only the glasses.

  Hereinafter, an embodiment of an image display apparatus and method according to the present invention will be described with reference to the drawings. In the following drawings, the scale of each member is appropriately changed in order to make each member a recognizable size.

  FIG. 1 is a perspective view showing a schematic configuration of an image display device 1 of the present embodiment. As shown in this figure, the image display device 1 according to the present embodiment includes a display device 2 (display means) and glasses 3.

  The display device 2 displays images belonging to different contents in a time division manner. FIG. 2 is a block diagram showing the functional configuration of the display device 2. As shown in FIG. 2, the display device 2 includes a signal processing unit 21, an infrared light emitting LED (Light Emitting Diode) 22 (invisible light emitting means), a projector 23, and a screen 24.

The signal processing unit 21 is connected to the projector 23 and outputs an image signal input from the outside toward the projector 23 at a predetermined timing. The signal processing unit 21 receives image signals of a plurality of contents (for example, news programs, dramas, and stereoscopic image programs). Then, the signal processing unit 21 divides the image signals of the plurality of contents in units of frames, for example, and outputs them in time division. Note that when the signal processing unit 21 divides the image signal, it is not always necessary to divide the image signal in units of frames, and the image signal may be divided more finely or roughly. The signal processing unit 21 repeatedly outputs image signals in the order of news programs, dramas, and stereoscopic image programs, for example.
In addition, the signal processing unit 21 outputs an audio signal input from the outside via an antenna or the like.

  The signal processing unit 21 is also connected to the infrared light emitting LED 22, and outputs a drive signal for driving the infrared light emitting LED 22 in synchronization with an image signal output to the projector 23. The signal processing unit 21 outputs different drive signals according to the type (content) of the image signal output by itself. That is, the drive signal corresponding to the case where the image signal of the news program is output, the case where the image signal of the drama is output, and the case where the stereoscopic image program is output is output toward the infrared light emitting LED 22. The signal processing unit 21 will be described in detail later when outputting a stereoscopic image program. The signal processing unit 21 outputs an image signal corresponding to a right-eye image among parallax images and corresponds to a left-eye image among parallax images. When the image signal to be output is output, a different drive signal is output to the infrared light emitting LED 22 according to the output.

  The infrared light emitting LED 22 emits infrared light, which is light not included in the visible region, in accordance with a drive signal input from the signal processing unit 21. The infrared light emitting LED 22 emits light by changing the light emission time and the light emission pattern according to the type of the drive signal input from the signal processing unit 21.

The projector 23 displays an image on the screen 24 by projecting image light toward the screen 24 in accordance with the image signal input from the signal processing unit 21.
Here, since image signals of a plurality of contents are input to the projector 24 from the signal processing unit 21 in a time division manner, in the image display device 1 of the present embodiment, images belonging to different contents are displayed on the screen 24. Displayed in time division. That is, images are repeatedly displayed in the order of news program, drama, and stereoscopic image program. As the projector 23, a projector provided with a liquid crystal light valve as a light modulation element, a projector provided with a digital micromirror device (DMD: registered trademark), or the like can be used.

  Returning to FIG. 1, the spectacles 3 are worn by the viewer, and a right-eye transmission part 31, a left-eye transmission part 32, and a speaker 33 (audio output part), which are liquid crystal shutters (selection means), are integrally formed. It has been done.

  FIG. 3 is a block diagram showing a functional configuration of the glasses 3. As shown in this figure, the glasses 3 include a mode selector switch 34, an infrared light receiving element 35 (light receiving unit), and a transmission unit driving unit in addition to the right eye transmitting unit 31, the left eye transmitting unit 32, and the speaker 33. 36 and an audio signal reception selection unit 37.

  The mode changeover switch 34 is a switch for changing the content visually recognized by the viewer. In the image display device 1 of the present embodiment, the mode changeover switch 34 can be switched by the viewer. The mode switch 34 is arranged as a slide switch or the like on the surface of the glasses 3, for example.

  The infrared light receiving element 35 receives infrared light emitted from the infrared light emitting LED 22 provided in the display device 2 and outputs a signal indicating the result as a synchronization signal. Has been. Here, the infrared light emitting LED 22 provided in the display device 2 emits light by changing the light emission time and the light emission pattern according to the type of the drive signal input from the signal processing unit 21. Since this drive signal differs depending on the type of image signal input to the projector 23, the output result (synchronization signal) of the infrared light receiving element 35 differs depending on the type of image displayed on the screen 24. It will be.

  The transmission unit driving unit 36 is for driving the right-eye transmission unit 31 and the left-eye transmission unit 32 that are liquid crystal shutters, and is connected to each of the mode changeover switch 34 and the infrared light receiving element 35. Then, the transmission unit driving unit 36 obtains information about what content the viewer is going to view from the mode changeover switch 34, and the viewer desires the mode changeover switch 34 from the infrared light receiving element 35. The timing at which the image of the obtained content is displayed on the screen 24 is acquired, and the right-eye transmission unit 31 and the left-eye transmission unit 32 are driven based on these information. Specifically, the right-eye transmission unit 31 is configured such that image light is transmitted through the right-eye transmission unit 31 and / or the left-eye transmission unit 32 only when an image of content desired by the viewer is formed on the screen 24. And the left-eye transmission part 32 is driven.

For example, when the viewer desires to watch a news program, the right-eye transmission unit 31 and the left-eye transmission unit 32 emit image light only when an image belonging to the news program is displayed on the screen 24. Driven to penetrate. As a result, the image belonging to the drama and the image belonging to the stereoscopic image program are not reached by the viewer, so that the viewer can view the news program.
When the viewer desires to watch a drama, the right-eye transmission unit 31 and the left-eye transmission unit 32 transmit image light only when an image belonging to the drama is displayed on the screen 24. To be driven. As a result, the image belonging to the news program and the image belonging to the stereoscopic image program do not reach the viewer, so that the viewer can appreciate the drama.
When the viewer desires to view a stereoscopic image program, the right-eye transmission unit 31 transmits the image light only when the right-eye image of the parallax image is displayed on the screen 24. Only when the left-eye image of the parallax image is displayed on the screen 24, the left-eye transmission unit 32 is driven to transmit the image light. As a result, the left eye image among the images belonging to the news program, the images belonging to the drama, and the parallax images does not reach the viewer's right eye, and the right eye among the images belonging to the news program, the images belonging to the drama, and the parallax images. Since the image for use does not reach the left eye of the viewer, the viewer can view the stereoscopic image.

The audio signal reception selection unit 37 selects an audio signal input from the signal processing unit 21 of the display device 2 via an antenna or the like and outputs it to the speaker 33 and is connected to the mode switch 34. Yes. Then, the audio signal reception selection unit 37 acquires information about which content the viewer is going to view from the mode changeover switch 34, and selects and outputs an audio signal based on this information.
The speaker 33 outputs sound based on the sound signal input from the sound signal reception selection unit 37. As a result, only the sound corresponding to the content desired by the viewer can be provided.

The glasses 3 are equipped with a power supply source (not shown) (for example, a battery), and power is supplied from the power supply source to the transmission unit drive unit 36 and the audio signal reception selection unit 37.

Further, in the image display device 1 of the present embodiment, the synchronizing means of the present invention is configured to include the infrared light emitting LED 22 and the infrared light receiving element 35.

  Next, the operation (image display method) of the image display device 1 of the present embodiment configured as described above will be described.

  First, when image signals of a plurality of contents are input to the signal processing unit 21 from the outside, the signal processing unit 21 divides the image signals of the plurality of contents into, for example, frame units and outputs them in a time division manner. FIG. 4 shows an example of an image signal output from the signal processing unit 21. As shown in this figure, the signal processing unit 21 repeatedly outputs image signals in the order of, for example, an image signal (a) belonging to a stereoscopic image program, an image signal (b) belonging to a news program, and an image signal (c) belonging to a drama. To do. Since the image signal belonging to the stereoscopic image program is a parallax image signal as described above, the signal processing unit 21 outputs the image signal of the right-eye image when outputting the image signal belonging to the stereoscopic image program. (A1) and the image signal (a2) of the image for the left eye are output alternately.

  In addition, the signal processing unit 21 outputs image signals of a plurality of contents in a time division manner, and at the same time outputs a drive signal for driving the infrared light emitting LED 22. As described above, the drive signal has a different pulse width and pattern depending on the type of the image signal output from the signal processing unit 21, and synchronizes the image signal output from the signal processing unit 21. Is output.

FIG. 5 is an example of a drive signal output from the signal processing unit 21. In the image display apparatus 1 and method of the present embodiment, 4 msec is a unit time, and the previous drive signal is repeatedly output every 4 msec until a different drive signal is output.
As shown in this figure, for example, when the signal processing unit 21 outputs the image signal (a1) of the right-eye image among the image signals belonging to the stereoscopic image program, a pulse signal having a pulse width of 0.5 msec is a unit. It is output only once during the time. Further, when the signal processing unit 21 outputs the image signal (b) belonging to the news program, a pulse signal having a pulse width of 1.5 msec is output only once per unit time. When the signal processing unit 21 outputs the image signal (c) belonging to the drama, a pulse signal having a pulse width of 2.5 msec is output only once per unit time. When the signal processing unit 21 outputs the image signal (a2) of the left-eye image among the image signals belonging to the stereoscopic image program, a pulse signal having a pulse width of 0.5 msec is first output during the unit time. After that, a pulse signal having a pulse width of 1.0 msec is output at intervals of 1.0 msec. That is, when the image signal (a2) of the left-eye image among the image signals belonging to the stereoscopic image program is output, the drive signal is constituted by these two pulse signals.
In the image display device 1 and method of the present embodiment, each drive signal is output from the signal processing unit 21 3 msec before the image signal corresponding to each drive signal is output from the signal processing unit 21. As a result, the output timing of the image signal and the output timing of the drive signal are synchronized.

  The image signal output from the signal processing unit 21 is then input to the projector 23. Then, the projector 23 projects image light based on the input image signal toward the screen 24. As a result, an image based on the image signal is displayed on the screen 24. Here, in the image display device 1 and method of the present embodiment, the image signal of a plurality of contents is output from the signal processing unit 21 in a time division manner. For this reason, the images displayed on the screen 24 are also displayed in a time-division manner. Specifically, images of a plurality of contents such as a stereoscopic image program (right eye image), a news program, a drama, a stereoscopic image program (left eye image), a news program, and a drama are sequentially displayed.

  The drive signal output from the signal processing unit 21 is then input to the infrared light emitting LED 22. The infrared light emitting LED 22 outputs infrared light based on the input drive signal. Specifically, infrared light is emitted when the pulse signal constituting the drive signal is High. For example, when the signal processing unit 21 outputs the image signal (a1) of the right-eye image among the image signals belonging to the stereoscopic image program, a pulse signal having a pulse width of 0.5 msec is input as a drive signal. The infrared light emitting LED 22 emits light for the first 0.5 msec during a unit time (4 msec). When the signal processing unit 21 outputs an image signal (b) belonging to a news program, a pulse signal having a pulse width of 1.5 msec is input as a drive signal. Emits light for the first 1.5 msec. When the signal processing unit 21 outputs an image signal (c) belonging to a drama, a pulse signal having a pulse width of 2.5 msec is input as a drive signal. Emits light for the first 2.5 msec. Further, when the signal processing unit 21 outputs the image signal (a2) of the left-eye image among the image signals belonging to the stereoscopic image program, the pulse signal is separated from the pulse signal having a pulse width of 0.5 msec, and then 1.0 msec. Since a pulse signal having a pulse width of 1.0 msec is input as a drive signal, the infrared light emitting LED 22 emits light for the first 0.5 msec during a unit time, then turns off for 1.0 msec, and again for 1.0 msec. Emits light. As described above, each drive signal is output from the signal processing unit 21 3 msec before the image signal corresponding to each drive signal is output from the signal processing unit 21. Driving is started by a driving signal corresponding to the content 3 msec before the image of the content is displayed on the screen 24.

  On the other hand, in the glasses 3, when the infrared light receiving element 35 receives the infrared light emitted from the infrared light emitting LED 22 of the display device 2, a signal indicating the result is amplified via an AMP (amplifier). This is input to the transmission unit driving unit 36. In the image display device 1 and method of the present embodiment, a signal (synchronization signal) indicating the light reception result output from the infrared light receiving element 35 is a drive signal input to the infrared light emitting LED 22 of the display device 2. It shall be the same.

  As described above, when a signal indicating the light reception result is input to the transmission unit driving unit 36, the transmission unit driving unit 36, based on the signals indicating the light reception result, transmits the right-eye transmission unit 31 and the left-eye transmission unit 32. Drive. Specifically, the image light is transmitted through the right-eye transmission unit 31 and / or the left-eye transmission unit 32 when an image of the content desired by the viewer, that is, the mode switch 34 is set on the screen 24 is displayed. To drive.

Here, an example of a method in which the transmission unit driving unit 36 determines which content image is displayed on the screen 24 will be described.
As described above, the signal indicating the light reception result input to the transmission unit driving unit 36 is the same as the signal input to the infrared light emitting LED 22.
Therefore, when the right-eye image among the images belonging to the stereoscopic image program is displayed on the screen 24, a pulse signal having a pulse width of 0.5 msec is input to the transmission unit drive unit 36. When an image belonging to a news program is displayed on the screen 24, a pulse signal having a pulse width of 1.5 msec is input to the transmission unit driving unit 36. When an image belonging to a drama is displayed on the screen 24, a pulse signal having a pulse width of 2.5 msec is input to the transmission unit driving unit 36. Further, when the left-eye image among the images belonging to the stereoscopic image program is displayed on the screen 24, a pulse signal having a pulse width of 0.5 msec is transmitted to the transmission unit driving unit 36, and then 1.0 msec apart. The pulse signal having a pulse width of 1.0 msec is input.

The transmission unit driving unit 36 determines that the first pulse signal is input as the start of a unit time (here, 4 msec), and measures the voltage value of the signal every 1 msec in this unit time. It is determined whether or not an image of the content is displayed on the screen 24.
Specifically, in the case where a pulse signal having a pulse width of 0.5 msec is input, the transmission unit driving unit 36 has a low signal voltage after 1 msec and a low signal voltage after 2 msec. Of the images belonging to the stereoscopic image program are determined to be displayed on the screen 24. Further, when a pulse signal having a pulse width of 1.5 msec is input, the transmission unit driving unit 36 has a high signal voltage after 1 msec and a low signal voltage after 2 msec. It is determined that an image belonging to is displayed on the screen 24. In addition, when a pulse signal having a pulse width of 2.5 msec is input, the transmission unit driving unit 36 has a signal voltage after 1 msec. High, and a signal voltage after 2 msec. It is determined that the image to which it belongs is displayed on the screen. In addition, when a pulse signal having a pulse width of 0.5 msec and a pulse signal having a pulse width of 1.0 msec separated by 1.0 msec are input thereafter, the transmission unit driving unit 36 outputs a signal voltage after 1 msec. Is low, and the signal voltage after 2 msec becomes High, and therefore it is determined that the left-eye image is displayed on the screen 24 in the stereoscopic image program.

Then, based on this determination, the transmission unit driving unit 36 controls the right-eye transmission unit 31 and / or the left-eye transmission unit 32 when the content image to which the mode change switch 34 is set is displayed on the screen 24. Is driven to pass through.
Specifically, when the mode changeover switch 34 is set to a stereoscopic image program, the transmission unit driving unit 36 images the right-eye transmission unit 31 when a pulse signal having a pulse width of 0.5 msec is input. When the pulse signal with a pulse width of 0.5 msec and a pulse signal with a pulse width of 1.0 msec separated by 1.0 msec are input after driving to transmit light, the left-eye transmission unit 32 is imaged. Drive to transmit light. By driving the right-eye transmission unit 31 and the left-eye transmission unit 32 in this way, only the right-eye image of the images belonging to the stereoscopic image program among the images displayed on the screen 24 is displayed by the viewer. Only the left eye image among the images belonging to the stereoscopic image program is reached to the left eye of the viewer. Accordingly, the viewer can view the stereoscopic image program.
When the mode changeover switch 34 is set to a news program, the transmission unit driving unit 36 receives the right eye transmission unit 31 and the left eye transmission unit 32 when a pulse signal having a pulse width of 1.5 msec is input. Is driven so that the image light is transmitted. Then, by driving the right-eye transmission unit 31 and the left-eye transmission unit 32 in this manner, among the images displayed on the screen 24, an image belonging to the news program reaches the viewer. Therefore, the viewer can view the news program.
Further, when the mode changeover switch 34 is set to the drama, the transmission unit driving unit 36 causes the right-eye transmission unit 31 and the left-eye transmission unit 32 to be turned on when a pulse signal having a pulse width of 2.5 msec is input. Drive to transmit image light. Then, by driving the right-eye transmission unit 31 and the left-eye transmission unit 32 in this manner, an image belonging to the drama among the images displayed on the screen 24 reaches the viewer. Therefore, the viewer can visually recognize the drama.

  In the image display device 1 and method of the present embodiment, as described above, the drive signal output from the signal processing unit 21 of the display device 2 toward the infrared light emitting LED 22 is transmitted from the signal processing unit 21 to the projector 23. Is output 3 msec before the image signal output toward. Therefore, a signal indicating a reception result is input from the infrared light receiving element 35 to the transmission unit driving unit 36 3 msec before an image based on the image signal is displayed on the screen 24. For this reason, the transmission unit drive unit 36 is provided with a preparation time for driving the right-eye transmission unit 31 and the left-eye transmission unit 32. Therefore, it is possible to completely synchronize the right-eye transmission unit 31 and the left-eye transmission unit 32 with the timing at which an image of a desired content is displayed on the screen 24.

  The audio signal output from the signal processing unit 21 is input to the audio signal selection unit 37 of the glasses 3 via an antenna or the like. Then, the audio signal selection unit 37 selects an audio signal corresponding to the content to which the mode switch 34 is set and outputs it to the speaker 33. As a result, the audio of the content desired by the viewer is output from the speaker 33. For this reason, the viewer can listen to the sound corresponding to the content.

According to the image display device 1 and the method of the present embodiment as described above, images belonging to different contents are displayed in a time-sharing manner, and the images are synchronized with the timing at which images belonging to the same content desired by the viewer are displayed.
