- the user when the 2D broadcast is switched to the 3D broadcast and the 2D video is automatically output, the user has no awareness that the 3D broadcast is received. Therefore, the user may continue to view the 3D broadcast without noticing the 2D video without wearing the dedicated glasses 103 or switching the image output mode.
- 2D video is displayed and a screen display indicating “3D broadcast” is displayed, so that the user can recognize that the 3D broadcast is being received. Therefore, the user can recognize that the 3D broadcast is being received, and can obtain the effect that the user can watch in the 3D mode with the dedicated glasses 103.

- the dedicated glasses 103 After the user puts on the dedicated glasses 103, it is possible to display in 2D mode regardless of 2D broadcasting or 3D broadcasting. Conventionally, for example, when switching to 3D broadcasting, the mode is automatically switched to 3D mode. At this time, if the user does not wear the dedicated glasses 103, the 2D broadcast video may be viewed in the 3D mode, which may cause discomfort. However, in this embodiment, an effect that the above problem can be avoided is obtained.
- the difference between the left part and the right part in the 2D video is small because there is not much correlation, but the left half (for the left eye) also in the original video of 3D video (video as shown in FIG. This is because the difference between the video and the right half (the video for the right eye) is not completely the same, and the difference may increase depending on the video.
- the difference extraction unit 5 not only the difference extraction unit 5 but also the scene change detection unit 3 is provided, and the determination is made using the difference result of the difference extraction unit 5 at the scene change point. Therefore, only the difference extraction unit 5 is used. Therefore, it is possible to ensure higher detection accuracy than the determination method.
- a 2D video when switching from 2D broadcasting to 3D broadcasting or from 3D broadcasting to 2D broadcasting, for example, a 2D video changes from a side-by-side video or a side-by-side video to a 2D video. Indicates the scene change point. Therefore, erroneous detection can be prevented by providing the scene change detection unit 3 and using it together with the difference extraction unit 5.
- the display mode of the stereoscopic display device is the 3D mode even if the broadcast is a 2D broadcast, the program that can be enjoyed in the 2D mode without the dedicated glasses 103 is displayed as such. There is a possibility that the user may watch the program while wearing the dedicated glasses 103 without noticing that the program is a simple program.
- the mode currently displayed on the stereoscopic video display apparatus 101 is not displayed, but whether the video system currently broadcast (or reproduced) is the 2D system or the 3D system. Is displayed. That is, in this embodiment, when the broadcast is switched from 2D broadcast to 3D broadcast or from 3D broadcast to 2D broadcast, whether the 3D display device 101 is in the 2D broadcast or the 3D broadcast is displayed. Therefore, the inconvenience as in the prior art does not occur.
- whether the current display mode is 2D mode or 3D mode may be displayed together.
- Japanese Patent Laid-Open No. 2003-333624 discloses a method of displaying in advance whether a program list is a 2D broadcast or a 3D broadcast in a program list or a recording list.
- a method of displaying in a list in this way it is difficult to display on the list when 2D broadcasting and 3D broadcasting are switched in the middle of a program.

Abstract
Description
1.構成
第1の実施の形態について説明する。図1は、立体映像表示システムのブロック図である。立体映像表示システム100は、立体映像を表示する立体映像表示装置101と、立体映像表示装置101に表示された立体映像を視聴するための専用メガネ103とを備える。立体映像表示装置101には再生装置102が接続されている。
次に、立体映像表示システム100の全体の動作を説明する。図5Aは、ユーザの状態が5段階(フェーズ1からフェーズ5)に遷移する場合の、ユーザの状態、スイッチ26の状態、放送方式、出画モード(出力モード)の関係を示している。
以上説明したように、第1の実施の形態によれば、放送方式が2D放送と3D放送との間で切り替わったときにおけるユーザの視聴のための利便性の向上を図ることができる。
以上説明した本実施の形態と従来技術との差異を具体的に説明する。まず、入力映像が2D映像か3D映像かを判別する手段について差異を説明する。従来技術としては、例えば特開平7-336729号公報に開示された技術がある。この技術は、相関を利用して判定するものであるが、これは、本実施の形態では差分抽出部5に相当するものである。従来技術では、このように差分(または相関)のみを利用して2D映像か3D映像かを判定しているが、このような場合、映像の内容によっては、誤った検出を行ってしまう可能性がある。なぜならば、例えばサイドバイサイド方式の場合、2D映像において左部分と右部分との差分はあまり相関がないので小さくなるが、3D映像の元映像(図7Aのような映像)においても左半分(左目用映像)と右半分(右目用映像)は完全に同じ映像というわけではないので、映像によっては、差分が大きくなってしまうこともありうるからである。しかし、本実施の形態においては、差分抽出部5だけでなくシーンチェンジ検出部3を設け、シーンチェンジ点における差分抽出部5の差分結果をつかって判定するので、差分抽出部5のみを利用して判定する方法にくらべ、より高い検出精度を確保することが可能となる。つまり、2D放送から3D放送または3D放送から2D放送に切り替わる場合、例えば2D方式の映像からサイドバイサイド方式の映像またはサイドバイサイド方式の映像から2D方式の映像に変化するが、このような変化点は、必ずシーンの切り替わり点を示す。したがって、シーンチェンジ検出部3を設けて差分抽出部5と併用することで、誤検出を防ぐことができる。
次に、第2の実施の形態について説明する。本実施形態は、放送信号として、2D放送信号とトップアンドボトム方式の3D放送信号が送信される場合を想定している。
次に、第3の実施の形態について説明する。本実施形態は、放送として、2D放送信号、サイドバイサイド方式及びトップアンドボトム方式の両方の3D放送信号が送信される場合を想定している。
