  The best mode for carrying out the present invention will be described below with reference to the drawings.

[Example 1]
FIG. 1A is a diagram showing a configuration example of a multi-view display device (“MV device”) 1 to which the present invention is applied. The MV device 1 includes a rearrangement unit 10, a mute image insertion unit (hereinafter “insertion unit”) 20, a microcomputer 30, and a TFT (Thin Film Transistor) type liquid crystal display (hereinafter “TFT”) 40. Is done.

  When the image to be displayed on the driver seat side and the image to be displayed on the passenger seat side are input, the rearrangement unit 10 rearranges the pixels of these two images alternately on one line. Output. Here, the two images are a map image, an NTSC image, and the like. The NTSC image includes an image reproduced from a DVD reproducing apparatus and a TV image received by an antenna, and the input of these images to the rearrangement unit 10 is switched according to a switching instruction by the user.

  The insertion unit 20 receives the image from the rearrangement unit 10 and the video mute image, inserts the mute image into the image from the rearrangement unit 10 and outputs the result. In the first embodiment, the mute image is a black image and is generated by an input signal from a grounded signal line as shown in FIG.

  The TFT 40 receives the output image from the insertion unit 20 and displays this output image. A slit portion having a slit having a predetermined pixel width is provided on the front surface of the TFT 40 in the vertical direction of the TFT 40 screen. By changing the viewpoint using the slit portion, for example, a user sitting in the driver's seat can see a map image, and a user sitting in the passenger seat can see an NTSC image.

  The microcomputer 30 outputs a control signal to the insertion unit 20 when a switching instruction is given by the user. The insertion unit 20 switches between the image from the rearrangement unit 10 and the mute image based on this control signal. By this switching, a mute image is inserted and video mute is performed.

  The operation of the MV device 1 configured as described above will be described with reference to FIG. For example, it is assumed that a user on the passenger seat side switches from an NTSC image reproduced from a DVD to a TV image received by an antenna by operating a predetermined operation button.

  When the microcomputer 30 detects the operation of the operation button, the microcomputer 30 outputs a control signal to insert a mute image when the video is switched. Based on this control signal, the insertion unit 20 switches the image from the rearrangement unit 10 to a mute image (black image) and outputs it.

  Since the mute image is inserted into the output image of the rearrangement unit 10, the mute image of the black image is inserted at the timing when the DVD image is switched to the TV image, and the mute image is also displayed on the map image at that timing. Inserted.

  The switching to the mute image is performed over one frame period or several frame periods. Thereafter, the insertion unit 20 switches to a TV image and a map image and outputs them. Therefore, as shown in FIG. 1B, the TFT 40 displays an image that has been muted at the same timing on both the driver seat side and the passenger seat side.

  Here, the switching will be described in detail. First, the insertion unit 20 outputs the image from the rearrangement unit 10, that is, the image composed of the map image and the NTSC image reproduced on the DVD, to the TFT 40. While this output is being performed, the microcomputer 30 outputs a control signal to the insertion unit 20 when detecting a switching instruction by the user, that is, a switching operation of the operation button. The timing at which this control signal is output is a timing that matches the vertical synchronization signal of the image output from the insertion unit 20 to the TFT 40. Upon receiving this control signal, the insertion unit 20 stops outputting the image from the rearrangement unit 10 to the TFT 40, and simultaneously outputs the mute black image to the TFT 40. By this operation, the TFT 40 switches the display of the image composed of the map image and the NTSC image of the DVD to the black image display.

  On the other hand, according to the switching instruction from the user, the rearrangement unit 10 is switched from the input of the NTSC image by the DVD reproduction input so far to the input of the TV image. Note that the NTSC image by DVD reproduction is input to the rearrangement unit 10 at least up to the position of the vertical synchronization signal. The TV image is not synchronized with the map image at the beginning of input to the sorting unit 10. In order to synchronize, the rearrangement unit 10 or its front part is provided with a buffer (not shown), and the synchronization with the map image is adjusted using the buffer. The rearrangement unit 10 rearranges the map image and the TV image and outputs them to the insertion unit 20 without synchronization, during the period from the beginning of the TV image input until the synchronization is achieved. Therefore, if an image in the meantime is output from the insertion unit 20 to the TFT 40, the TFT 40 outputs an unsynchronized TV image and displays a distorted image. In order to eliminate this problem, the insertion unit 20 is configured to output a mute image to the TFT 40 at least during the period from the beginning of TV input until synchronization is achieved. Therefore, as a timing, the insertion unit 20 receives an input of an image composed of a map image and a TV image from the rearrangement unit 10 after the start of the output of the black image to the TFT 40. Then, output of a black image is stopped at a certain vertical synchronization timing after a predetermined period, and output of an image composed of a map image and a TV image is started. This predetermined period is a period required for synchronizing, for example, one frame period or several frame periods. If it is a mute image of several frames, the visibility of the map image is not so badly affected, and the visibility effect by not displaying the disturbance of the TV image is higher than that.

  As a result, it is possible to prevent image disturbance caused by image switching.

[Example 2]
Next, Example 2 will be described. In the first embodiment, the video mute is performed on both the driver seat side image and the passenger seat side image at the same timing. In the second embodiment, these two videos are muted at individual timings.

  FIG. 2 is a diagram illustrating a configuration example of the MV apparatus 1 according to the second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals.

  In the MV device 1, a first insertion unit 21 and a second insertion unit 22 for inserting a mute image are provided in the previous stage of the rearrangement unit 10. These insertion sections 21 and 22 also insert a mute image (black image) by switching over one frame or several frames to the ground side input based on a control signal from the microcomputer 30.

  By varying the timing at which the control signal is output from the microcomputer 30, video muting can be performed at individual timing.

  More specifically, the insertion unit 21 outputs the input map image to the rearrangement unit 10, and inserts a mute image when the type of the map image is switched. Here, the types of map images include, for example, a travel restriction image and a normal map image other than the travel restriction image. In addition, the travel restriction image is an image configured in accordance with the travel restriction, for example, by hiding a touch panel button that requires an operation of two steps or more. A normal map image is input to the insertion unit 21 while the vehicle is stopped, and a travel regulation image is input when the vehicle starts traveling.

  The microcomputer 30 outputs a control signal to the insertion unit 21 when detecting the start of traveling. The timing at which this control signal is output is a timing that matches the vertical synchronizing signal of a normal map image. Upon receiving this control signal, the insertion unit 21 stops outputting a normal image to the rearrangement unit 10 and outputs a mute image to the rearrangement unit 10 simultaneously with the stop. It is desirable that the period during which the mute image is output includes at least the period from the start of input of the newly input travel restriction image until the synchronization can be achieved. When the travel restriction image is synchronized, the insertion unit 21 switches from the output of the mute image to the output of the travel restriction image at the timing of the next vertical synchronization signal. The same applies when switching from a travel restriction image to a normal map image.

  The insertion unit 22 outputs the input NTSC image or TV image by DVD reproduction to the rearrangement unit 10, and inserts a mute image when the two images are switched. When the control signal is output from the microcomputer 30 that has detected the switching instruction by the user, the insertion unit 22 stops outputting the image that has been input to the rearrangement unit 10, and at the same time the muted image is displayed. The data is output to the sorting unit 10. The period during which the mute image is output is preferably a period including at least the start of input of a newly input TV image until the synchronization can be achieved. When the TV image is synchronized, the insertion unit 22 switches from the output of the mute image to the output of the TV image at the timing of the T-th vertical synchronization signal. The same applies when switching from a TV picture to an NTSC picture by DVD playback.

  The operation in this case will be described. As shown in FIG. 2B, a case is considered where a map image is displayed on the driver's seat side and an NTSC image from a DVD is displayed on the passenger seat side.

  For example, it is assumed that a map image is displayed when the vehicle is stopped, and the driver switches the image to the travel restriction image by moving the vehicle. At this time, since the displayed video is switched from the map image to the travel restriction image, it is necessary to insert a mute image.

  When the microcomputer 30 detects a travel start operation of the vehicle, such as movement of the vehicle, the microcomputer 30 outputs a first control signal to the first insertion portion 21. The first insertion unit 21 selects and outputs a ground-side input, that is, a black mute image, over one frame or a plurality of frames based on the first control signal. Therefore, as shown in FIG. 2B, a video with a mute image inserted is output. Thereafter, the first insertion portion 21 switches to the input travel restriction image and outputs it.

  On the other hand, when the user sitting in the passenger seat while traveling operates the operation button to switch from the DVD image to the TV image, the microcomputer 30 detects the switching, and the second insertion unit 22 detects the second. Output a control signal. Based on this control signal, the second insertion unit 22 outputs a black image over one frame or several frames. Thereafter, the video with the mute image inserted is displayed by switching to output the TV image.

  By performing video muting at an individual timing, a muted image is not displayed on the other video and is not affected by the muting, so that the video can be switched without conspicuous. Further, even if the video is switched, the video is not disturbed on both the driver's seat side and the passenger seat side.

[Example 3]
Next, Example 3 will be described. The third embodiment is an example in which a mute image of a designated color is inserted into both two videos at the same timing.

  FIG. 3A is a diagram illustrating a configuration example of the MV device 1 according to the third embodiment. The same number is attached | subjected to the same structure as Example 1 (FIG. 1) etc. FIG. The MV device 1 further includes a register 50 in which a mute image of a predetermined color is stored.

  Based on the control signal from the microcomputer 30, the insertion unit 20 switches to the mute image of the register 50 and outputs it, thereby performing video mute.

  The operation will be described with reference to the example shown in FIG. The rearrangement unit 10 receives a map image and an NTSC image reproduced from a DVD. For example, when the user at the passenger seat operates the operation button to switch from the DVD image to the TV image, the microcomputer 30 detects the operation and outputs a control signal to the insertion unit 20. The insertion unit 20 reads out and outputs a mute image of a predetermined color (for example, blue) stored in the register 50 based on the control signal.

  Therefore, the mute image is inserted into the DVD image, and the same mute image is inserted into the map image as well. Thereafter, the insertion unit 20 switches to the output image from the rearrangement unit 10 and outputs it, so that the images of the TV image and the map image are displayed on the TFT 40, respectively.

  Also in this example, since the video mute is performed when the video is switched on the driver's seat side and the passenger seat side, the video disturbance at the time of switching can be eliminated.

  The color of the mute image stored in the register 50 is preferably a background color such as a map image or a travel regulation image. This is because if the mute image of the same color as the background color is displayed, the video is switched without conspicuous on the driver seat side or the passenger seat side.

  Furthermore, in the MV device 1, various images are input to the rearrangement unit 10 in various modes. For example, in the source switching mode, the video is switched from the DVD image to the TV image as described above, and in the TV channel switching mode, the video is switched from one channel to another channel. In the destination setting mode, the map image is switched to an image for setting the destination.

  Here, if the color of the mute image inserted into the insertion unit 20 can specify the background color of the mode before switching, the mute image can be made inconspicuous. For example, a blue mute image is inserted when switching from an audio mode (background color is blue) in which the name of the currently played audio song is displayed to a TV channel switching mode (background color is black).

  In such a case, mute images of a plurality of colors are stored in the register 50 so as to correspond to various modes. Further, the microcomputer 30 outputs a control signal designating a mute image of a color to be read out when switching the video to the register 50 and the insertion unit 20. The register 50 outputs a mute image of a designated color, and the insertion unit 20 switches and outputs the mute image at a video switching timing.

  In the present embodiment, the color of the mute image output from the register 50 may be determined as follows.

  That is, of the two inputs to the rearrangement unit 10, the inconspicuous color is set according to the image without switching. Examples of inconspicuous colors include, for example, a color close to the background color of the image without switching, a color most frequently included in the image, a color obtained by averaging the images included in the image, or the image The color is difficult for the user to identify in contrast with brightness and contrast.

  For example, when one input is switched between a DVD image and a TV image, and the other input is only a map image and there is no switching, the color of the mute image is made inconspicuous according to the map image. It is recognized that in the case of a map image that is generally popular in the market, if blue that is often used as a background color is muted, it is inconspicuous. If the user can customize the map color, the mute image may be determined according to the customized color.

  By matching the color of the non-switched image to the color of the non-switched image in this way, the non-switched mute image is not conspicuous, and the user viewing it is less likely to recognize the mute image. And no discomfort due to muted images. On the other hand, the direction of switching is usually based on a switching instruction from the user who is viewing the image, particularly when switching between a DVD image and a TV image. Therefore, since the user recognizes that the switching is performed by his / her own operation, the muted image at the time of switching should be less noticeable whether or not the color of the muted image is conspicuous. . Rather, the effect of not seeing the disturbance of the image is higher. The same technical idea may be applied to other embodiments.

  Further, when the register 50 holds a plurality of colors of the mute image, the color to be output may be changed depending on the time zone. For example, the feeling of the brightness of the screen display is different for the user between day and night. For this reason, if a mute image of the same color is inserted for both day and night, the color may be a color that does not stand out in the day but a color that does not stand out in the day. Therefore, according to a time zone corresponding to day or night, a color that is less noticeable in the time zone is set as a mute image. Specifically, a blue mute image at night and a black mute image at night can be considered. The blue mute image does not stand out in the daytime but looks too bright to the user at night. Therefore, at night, it is possible to prevent the user from feeling uncomfortable by using a black mute image with reduced brightness. The trigger for this switching may be, for example, a clock, illuminance of an optical sensor or the like, or an illumination switch. Not only the two types of blue and black, but a plurality of color mute images may be used depending on the external brightness.

  Further, a frame memory is provided in place of the register 50, and the frame memory has two colors of one pixel width so that mute images of different colors are displayed on the driver seat side and the passenger seat side, respectively. You may make it memorize | store the frame image of the vertical stripe which arranged the vertical line alternately. The two colors are preferably inconspicuous colors that match the two images input to the rearrangement unit 10, for example. For example, when the background color of the map image of one image is green and the background color of the DVD of the other image is blue, the frame memory stores a vertical stripe image composed of green and blue. With this configuration, during the mute image display period, the green mute image is displayed on the side where the map image is displayed, and the blue mute image is displayed on the side where the DVD image is displayed.

[Example 4]
Next, Example 4 will be described. The fourth embodiment is an example in which a video that is displayed on the driver's seat side and a video that is displayed on the front passenger seat side are switched by inserting mute images of the same color at individual timings.

  FIG. 4A is a diagram illustrating a configuration example of the MV device 1 according to the fourth embodiment. Similar to the second embodiment (FIG. 2A, etc.), the first insertion portion 21 and the second insertion portion 22 are provided in the previous stage of the rearrangement portion 10. The first register 51 and the second register 52 store the same color mute image as in the third embodiment, and output the same to the insertion units 21 and 22.

  For example, as shown in FIG. 3B, a map image is input to the first insertion unit 21 and an NTSC image from a DVD is input to the second insertion unit 22. The switching operation for inserting the mute image in each of the insertion units 21 and 22 is substantially the same as in the third embodiment.

  Based on the first control signal from the microcomputer 30, the first insertion unit 21 switches from the map image to the mute image and outputs it. In this case, since the microcomputer 30 does not output the first control signal to the second insertion unit 22, the mute image is not inserted into the DVD image. Then, the 1st insertion part 21 switches to a travel regulation picture.

  On the other hand, when the source is switched from DVD to TV, the microcomputer 30 outputs a second control signal to the second insertion unit 22. The second insertion unit 22 switches to output the same color mute image inserted by the first insertion unit 21 based on the second control signal. In this case, the second control signal is not output to the first insertion unit 21. Therefore, the mute image is not inserted into the travel restriction image. Thereafter, the second insertion unit 22 switches to the TV image.

  In this embodiment, mute images of the same color are individually inserted at the switching timing of each video, so that video disturbance can be eliminated. Further, since the mute is performed at individual timing, the other is not affected by the mute, and the video mute is performed without conspicuous.

[Example 5]
The fifth embodiment is an example in which video mute is performed by inserting mute images designated by individual colors at the same timing into videos displayed on the driver's seat side and the passenger seat side.

  The configuration of the MV device 1 in the fifth embodiment is the same as that shown in FIG. However, the registers 51 and 52 store mute images of different colors. Further, since the insertion is performed at the same timing, a control signal for switching is output from the microcomputer 30 to each of the insertion units 21 and 22 at the same timing.

  As shown in FIG. 5A, consider an example in which a travel restriction image 100 is input to the first insertion portion 21 and a DVD image is input to the second insertion portion 22. For example, it is assumed that the user on the passenger side switches the video from the DVD image to the TV image by operating the operation button.

  At this time, the microcomputer 30 outputs a control signal to the first insertion unit 21 and the second insertion unit 22 at the same timing. Based on this control signal, the first insertion unit 21 switches to a mute image (for example, blue) from the first register 51 and outputs it. The second insertion unit 22 also switches to the mute image (for example, black) from the second register 52 and outputs it.

  Accordingly, as shown in FIG. 5A, mute images of different colors are inserted at the same timing. Then, each insertion part 21 and 22 switches and outputs the input travel regulation image 200 and TV image.

  Examples of the travel regulation images 100 and 200 displayed on the TFT 40 are shown in FIGS. 5B and 5C, respectively. Buttons 110 and 210 are displayed on the screen at the upper left of the screen, respectively. This button indicates that a playback image from a DVD or a TV image can be viewed from the travel restriction image after the vehicle stops. As described above, since the travel regulation image 100 and the travel regulation image 200 are different travel regulation images, video muting is performed at the timing of video switching.

  By such video muting, it is possible to eliminate the disturbance of the video by switching each video.

  Similar to the third embodiment, the mute image output from the registers 51 and 52 may be the same color as the background color used in the mode before the video is switched. Therefore, a plurality of color mute images may be stored in the registers 51 and 52. This is because, if a mute image of any one color is output based on a control signal from the microcomputer 30, video mute according to a plurality of modes can be performed.

[Example 6]
Next, Example 6 will be described. Example 6 is an example in which video mute is performed by inserting mute images of individual colors at individual timings on the driver's seat side and the passenger seat side.

  The configuration of the MV device 1 in the sixth embodiment is the same as that in the fourth embodiment (see FIG. 4). However, control signals (a first control signal and a second control signal) output from the microcomputer 30 to the first insertion unit 21 and the second insertion unit 22 are output at individual timings.

  In the example illustrated in FIG. 6, when the travel restriction image 200 is displayed on the driver's seat side, the driver stops the vehicle and the display is switched to the TV image. The microcomputer 30 outputs a first control signal to the first insertion portion 21 at this timing. The first insertion unit 21 performs video mute by switching to the blue mute image from the first register 51.

  On the other hand, when the user on the passenger seat side switches from the TV image to the DVD image by operating the operation button or the like after the vehicle stops, the second insertion unit 22 performs the second operation based on the second control signal from the microcomputer 30. The register 52 is switched to a black mute image and output. Since the first control signal is not output to the second insertion unit 22 and the second control signal is not output to the first insertion unit 21, video muting can be performed at individual timings.

  The output shown in FIG. 6 is obtained by outputting the video after switching after inserting the mute image. Accordingly, since video muting is performed by inserting muted images with individual colors specified at individual timings, it is possible to prevent image disturbance at the time of switching on both the driver seat side and the passenger seat side. Further, since the individual muting is performed, the video muting can be performed without conspicuously affecting the other.

  Also in the sixth embodiment, a mute image having the same color as the background color used in the previous mode may be used. Therefore, the mute images of a plurality of colors are stored in the registers 51 and 52, and the mute image of any one color can be individually timed by a control signal from the microcomputer 30. By inserting a mute image of a color corresponding to a plurality of modes, it is possible to switch the video without conspicuous.

[Example 7]
The seventh embodiment is an example in which video mute is performed using a unique image as a mute image at the same timing on the driver seat side and the passenger seat side. An example of a unique image is a frame image immediately before a video switch.

  FIG. 7 is a diagram illustrating a configuration example of the MV device 1 according to the seventh embodiment. The insertion unit 23 includes a memory 231 and a selection unit 232. The memory 231 stores the frame image output from the sorting unit 10. It is sufficient to store at least one frame. The selection unit 232 outputs a frame image stored in the memory 231 based on a control signal from the microcomputer 30 that has detected an image switching instruction or the like. This is output for one frame period or several frame periods. Similar to the other embodiments, this period is a period necessary for the switched images to be synchronized, and in this embodiment, is one frame period. During this one frame period, while the selection unit 232 outputs the latest image stored in the memory 231, the switched image and the other image are synchronized, and the frame image without any disturbance is obtained. Then, the data is input from the rearrangement unit 10 to the selection unit 232. Then, the output video from the rearrangement unit 10 is switched.

  As a result, for example, as shown in FIG. 7B, the n-th frame map image immediately before switching during the mute period is displayed on the driver side, and the n-th frame DVD image is displayed on the passenger side. The After the mute period, the (n + 2) th frame map image and the first frame TV image are displayed.

  In this way, by inserting the frame image immediately before switching at the same timing as a mute image, it is possible to prevent image disturbance due to switching of images on both the driver seat side and the passenger seat side.

[Example 8]
Example 8 is an example in which video muting is performed by individually outputting unique images at the same timing to the driver seat side and the passenger seat side. The unique image is a frame image immediately before video switching.

  FIG. 8 is a configuration example of the MV device 1 in the eighth embodiment. The first insertion portion 24 and the second insertion portion 25 have the same configuration as the insertion portion 23 of the seventh embodiment. By selecting and outputting the frame images stored in the memories 241 and 251 by the selection units 242 and 252, the frame image is output as a mute image at the timing of video switching. These switching operations are performed based on a control signal from the microcomputer 30.

  In this case, individual frame images are inserted at the same timing, but the result is the same as in the seventh embodiment. This is because the frame image immediately before switching is a mute image.

  Also in the example of the eighth embodiment, it is possible to prevent the disturbance of the video due to the switching of the video on both the driver seat side and the passenger seat side.

[Example 9]
The ninth embodiment is an example in which video muting is individually performed on unique images at the driver seat side and the passenger seat side at individual timings. The unique image is a frame image immediately before switching as in the seventh embodiment.

  FIG. 8 is a configuration example of the MV device 1 in the ninth embodiment. The configuration is the same as that of the eighth embodiment. However, the microcomputer 30 is different in that the first control signal is output to the first insertion section 24 and the second control signal is output to the second insertion section 25 at different timings.

  Since the microcomputer 30 outputs the first control signal and the second control signal at the timing of switching of each video, even if the video on the driver's seat side and the passenger's seat side are switched at different timings, the video mute is performed only on each video. Is multiplied.

  For example, as shown in FIG. 8B, at the timing when the map image is switched to the travel restriction image, the immediately preceding n-th frame map image becomes a mute image and then becomes a travel restriction image. Also, the n-th frame DVD image is inserted as a mute image at the timing of switching from the DVD image to the TV image, and then becomes a TV image.

  In this way, by individually muting the video at each timing, even if each video is switched at different timings in both the driver's seat and the passenger seat, both can be switched to the next video without any video disturbance. Also, because of the individual timing, the other is not affected by muting.

[Other embodiments]
In Examples 1 to 9, map images and travel regulation images are taken as examples of driver side images, and NTSC images (TV images, images reproduced from DVDs, etc.) are taken as examples of passenger side images. However, this is an example, and for example, a map image on the passenger seat side and an NTSC image on the driver seat side may be displayed.

  In this case, it is also possible to display an NTSC image or the like on the driver seat side and a map image or the like on the passenger seat side by changing the pixel rearrangement of the rearrangement unit 10. The same effect as the above-described example is achieved.

  In addition, the TFT type has been described as an example of the liquid crystal display, but the present invention can be applied to various other types such as a STN (Super Twisted Nematic) type and a DSTN (Dual-scan Super Twisted Nematic) type. Is possible. Further, besides a liquid crystal display, a plasma display or an EL display (Electroluminescence display) can be applied. In either case, the same effects as those of the above-described embodiment can be obtained.
