Abstract

<P>PROBLEM TO BE SOLVED: To provide a reproduction device which can display a video whose top and bottom are reversed (180° rotation) with a simple structure, and can normally perform output to an outer unit and in which operability superior in intuition is realized even if the top and bottom are reversed. <P>SOLUTION: Since a display part 2 itself is constituted so as to reverse and display the video, the top and bottom of video data outputted from an AV OUT connector 5e are not reversed even if a system is set to a mode where the top and bottom are reversed. Thus, a regular screen where the top and bottom are not reversed can be displayed on a monitor of a television connected to the AV OUT connector 5e, for example. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a playback apparatus having a function of displaying an image by reversing the image, for example.

For example, Patent Document 1 discloses an apparatus having a function of displaying upside down. In the apparatus of this patent document 1, it is possible to invert the display of a liquid crystal panel with a touch panel for left-handed use, and at that time, assignment of arrow keys (up / down / left / right cursor keys) is also inverted.
JP 2002-215304 A

  However, in Patent Document 1, since the CPU is configured to generate a screen that reverses the top and bottom, for example, when an external terminal is provided and a function for outputting the screen to the outside is added, A screen with upside down is displayed. For this purpose, it is conceivable to provide a special processing apparatus, but there is a problem that the configuration becomes very complicated.

  An object of the present invention is to provide a playback apparatus that can display an image that is upside down (rotated 180 °) with a simple configuration and that can normally output to an external device. .

  Another object of the present invention is to provide a playback apparatus capable of realizing operability with excellent intuition even when the top and bottom are reversed.

  In order to achieve the above object, a playback apparatus according to the present invention displays at least an output means for outputting video data, video based on video data input from the output means, and the input video based on an upside down signal. A display unit capable of displaying a video with the top and bottom inverted from data, and a common arrangement that is arranged around the display unit and substantially parallel to the video displayed on the display unit. A pair of operation buttons to which functions that are opposite to each other are assigned, a control unit that outputs the top and bottom inversion signal and reverses the function assignment of the pair of operation buttons, and video data input from the output unit Are output to the outside.

  In the present invention, since the display unit can independently display the image upside down, the image data output from the output terminal is not inverted even if the image is inverted. Therefore, when an image is displayed on a monitor such as a television via the output terminal, the inverted image is not displayed. In addition, since the function assignment is reversed for a pair of operation buttons to which functions that are common but opposite to each other are assigned at the time of upside down, it is possible to realize operability with excellent intuition. It becomes possible.

  The functions that are common but have the opposite relationship include, for example, a function of fast-forwarding and rewinding video, a function of switching the screen from A → B → C, and a function of switching from C → B → A.

  The switching of the upside down may be set by the user on the screen, or may be automatically switched by providing a sensor for detecting the upside down.

  In the playback device of the present invention, the pair of operation buttons are provided with symmetrical display marks, and the control unit assigns functions to the other pair of operation buttons provided with left-right asymmetric display marks. It is characterized by regulating inversion.

  This is because if a function assignment is reversed for a pair of operation buttons provided with symmetrical display marks, an erroneous operation may be caused.

  Here, the left-right symmetric display marks are, for example, “←” and “→”, and the left-right asymmetric display marks are “enter” and “back”.

  As described above, according to the present invention, it is possible to display an image that is upside down (rotated 180 °) with a simple configuration, and in that case, it is possible to normally output to an external device. Intuitive operability can be achieved even when the screen is turned upside down.

  FIG. 6 is a diagram illustrating an example of the configuration of the display unit 2 described above.

  In FIG. 6, 2a is a first glass substrate, 2b is a second glass substrate, and liquid crystal is interposed between these glass substrates 2a and 2b and sealed.

  On the Y side of the protruding portion of the first glass substrate 2a, a large number of scanning wirings 2c are led out from the liquid crystal intervening part, and on the X side, a large number of data wirings 2d are led out from the liquid crystal interposing part.

  The scanning wiring 2c is connected with a normal scanning driver 2e and an upside down scanning driver 2f. A normal data driver 2g and an upside down data driver 2h are connected to the data wiring 2d.

  As the normal scanning driver 2e and the upside down scanning driver 2f, a driver in which the top and bottom are simply reversed and connected can be used. In addition, the normal data driver 2g and the upside-down data driver 2h can be used by simply reversing the left and right sides.

  The display control unit 2i performs processing for displaying the video data and the like input from the CPU / DSP unit 8 on the liquid crystal, and performs a normal scanning driver 2e, an upside down scanning driver 2f, and a normal data driver 2g. Alternatively, a predetermined signal is output to the data driver 2h for upside down.

  The display control unit 2i outputs a signal to a normal scanning driver 2e and a normal data driver 2g at a normal front desk, but when a top / bottom inversion signal is input from the CPU / DSP unit 8, Signals are output to the scanning driver 2f and the upside down data driver 2h.

Next, the relationship between the screen displayed on the display unit 2 and the operation buttons will be described.
In the reproducing apparatus 1, when the power switch 4b is turned on, the latest end state is reproduced based on the data stored in the sub CPU 16 (resume function). Assume that the title list screen of “Video” is displayed as shown in FIG. When the button 3b is pressed (touched) in this state, the “Music” title list screen shown in FIG. 8 is displayed. When the button → 3b is further pressed, the “Photo” title list screen shown in FIG. 9 is displayed. When the → button 3b is further pressed, a title list screen of “Setup” shown in FIG. 10 is displayed. When the ← button 3a is pressed, the title list screen is switched on the contrary. That is, by pressing the → button 3b, the title list screen is switched in the order of “Video”, “Music”, “Photo”, “Setup”, and by pressing the ← button 3a, the title list screen is “Setup”, It is switched in the order of “Photo”, “Music”, and “Video”. The screen can be switched between the normal screen shown in FIG. 11 and the upside down screen (screen rotated 180 °) shown in FIG. 12 by “screen rotation” of “Setup”. The upside down screen can be used by a left-handed user or when the user is tired from using a right-handed user.

  Next, such an upside down operation will be described based on the flowchart shown in FIG.

  When the screen is switched to the upside down screen as described above (step 1301), the upside down signal is output from the CPU / DSP unit 8 (step 1302), and this upside down signal is input to the display control unit 2i of the display unit 2. The display unit 2 displays a screen upside down, for example, an image. Along with this, the table shown in FIG. 14 (for example, stored in the flash memory 10) is read, and the button function assignment is changed from “standard” to “upside down” (step 1303).

  That is, in this example, the function assignment between the ← button 3a and the → button 3b is reversed. More specifically, the title list screen is switched in the order of “Video”, “Music”, “Photo”, “Setup” by pressing the → button 3b by default, and the title list is switched by pressing the ← button 3a. The screen has been switched in the order of “Setup”, “Photo”, “Music”, “Video”, but when the top / bottom is reversed, the title list screen can be switched to “Video”, “Music” by pressing the ← button 3a. , “Photo” and “Setup” are switched in order, and the title list screen is switched in the order of “Setup”, “Photo”, “Music” and “Video” by pressing the button 3b.

  In this state, since the video data output from the AV OUT connector 5e is not inverted, a normal screen that is not inverted is displayed on a monitor such as a television connected to the AV OUT connector 5e. .

  In addition, while the video file is being played as a standard, when the button 3b is pressed, fast forward is performed, and when the ← button 3a is pressed, fast reverse is performed. Press to fast return.

  On the other hand, when the screen is switched from the upside down screen to the standard screen (step 1501), a standard signal is output from the CPU / DSP unit 8 (step 1502), and this standard signal is input to the display control unit 2i of the display unit 2. The display unit 2 displays a standard screen, for example, an image. At the same time, the table shown in FIG. 14 (for example, stored in the flash memory 10) is read and the button function assignment is changed from “upside down” to “standard” (step 1503).

  As described above, in the playback device according to the present embodiment, the display unit 2 itself is configured to display the video by inverting it. Therefore, even if the top / bottom mode is set, the output from the AV OUT connector 5e is performed. The video data to be played is not inverted. Therefore, for example, a normal screen that is not upside down can be displayed on a monitor such as a television connected to the AV OUT connector 5e. In particular, the playback apparatus according to the present embodiment can realize such a function with a very simple configuration.

  In addition, this invention is not limited to said embodiment.

  In the above embodiment, when the upside down is reversed, the function assignment between the ← button 3a and the → button 3b is reversed. However, the function assignment between the ENTER button 3c and the BACK button 3d is reversed. But of course. In this case, it is more preferable that the display mark is symmetrical. FIG. 16 shows a table corresponding to FIG. 14 in such a case.

  In addition, by providing a table as shown in FIG. 17, a function that reverses the function assignment between the ← button 3a and the → button 3b can be brought to a position where the ENTER button 3c and the BACK button 3d are located. In other words, the standard ← button 3a and the → button 3b can be positioned below even if they are upside down. Further, by providing the table shown in FIG. 18, the ENTER button 3c and the BACK button 3d can be reversed.

  The firmware upgrade including such a table may be performed from the personal computer when the personal computer is connected to the USB connector 5d via a USB cable, for example. In that case, the upgrade data may be temporarily stored in the hard disk 6 and the upgrade may be approved by the user via the display unit 2. By having such an approval mode, it is possible to visually understand the upgrade when receiving upgrade data from a device that does not have a display unit and is not a personal computer.
