　本発明は、入力された情報に応じて画像処理する映像表示装置、プログラム、および記録媒体に関する。 The present invention relates to a video display device, a program, and a recording medium that perform image processing according to input information.
　デジタル映像信号を伝送するための規格として、ＤＶＩ（Ｄｉｇｉｔａｌ Ｖｉｓｕａｌ Ｉｎｔｅｒｆａｃｅ）規格が普及している。このＤＶＩ規格をさらに改良したデジタル信号伝送規格として、ＨＤＭＩ（Ｈｉｇｈ Ｄｅｆｉｎｉｔｉｏｎ Ｍｕｌｔｉｍｅｄｉａ Ｉｎｔｅｒｆａｃｅ）規格が採用されるようになってきている。 As a standard for transmitting a digital video signal, a DVI (Digital Visual Interface) standard is widely used. As a digital signal transmission standard obtained by further improving the DVI standard, the HDMI (High Definition / Multimedia / Interface) standard has been adopted.
　このＨＤＭＩ規格には、デジタル音声信号を多重化して音声伝送を行うことが可能であること、デジタル信号をＲ，Ｇ，Ｂ形式の他に色差（Ｙ，Ｃｂ，Ｃｒ）形式で伝送することが可能であること、ＵＳＢ（Ｕｎｉｖｅｒｓａｌ Ｓｅｒｉａｌ Ｂｕｓ）ライクの小型のＨＤＭＩコネクタで接続することが可能であることといった、ＤＶＩ規格にない種々の規定が盛り込まれている。 In the HDMI standard, it is possible to multiplex digital audio signals and perform audio transmission, and to transmit digital signals in color difference (Y, Cb, Cr) format in addition to R, G, B format. Various regulations not included in the DVI standard are incorporated, such as being capable of being connected with a USB (Universal Serial Bus) -like small HDMI connector.
　このため、テレビジョン信号受信機にＨＤＭＩ用の入力端子を設け、この入力端子に外部機器からＨＤＭＩ規格に準拠したデジタル信号を供給可能にしたものもある。なお、このような外部機器としては、例えばＤＶＤ（Ｄｉｇｉｔａｌ Ｖｅｒｓａｔｉｌｅ Ｄｉｓｋ）プレーヤ、ＤＶＤレコーダ、ＳＴＢ（セットトップボックス、Ｓｅｔ ｔｏｐ Ｂｏｘ）、ハイビジョンムービー、ＰＣ（パーソナルコンピュータ、Ｐｅｒｓｏｎａｌ Ｃｏｍｍｐｕｔｅｒ）などがあり、このような外部機器とテレビジョン信号受信機とをＨＤＭＩコネクタを介して接続するようにしている。 For this reason, some television signal receivers are provided with an input terminal for HDMI, and a digital signal compliant with the HDMI standard can be supplied to the input terminal from an external device. Examples of such external devices include a DVD (Digital Versatile Disk) player, a DVD recorder, an STB (Set Top Box, Set top box), a high-definition movie, a PC (personal computer, Personal Computer), and the like. An external device and a television signal receiver are connected via an HDMI connector.

　次に、ＨＤＭＩ信号処理部４１および画質パラメータ制御部４２の処理について、図２～図４を参照して説明する。図２は、本発明の映像表示装置１において、入力された情報に応じて画質パラメータを変更することによって、画像処理する流れを示すシーケンス図である。 Next, processing of the HDMI signal processing unit 41 and the image quality parameter control unit 42 will be described with reference to FIGS. FIG. 2 is a sequence diagram showing the flow of image processing by changing the image quality parameter in accordance with input information in the video display device 1 of the present invention.
　図２に示すように、まず、ＨＤＭＩ信号処理部４１に、外部入力部３１からＨＤＭＩ規格に準拠したデジタル信号が入力される（ステップＳ１）。ＨＤＭＩ信号処理部４１は、詳しくは参照する図面を替えて後述するが、入力されたデジタル信号を映像信号に復元するとともに、外部機器情報が取得可能か否かを判定する（ステップＳ２）。外部情報機器が取得可能である場合には、この外部機器情報をＳＰＤパケットに含まれる情報から取得して画質パラメータ制御部４２に出力する。なお、外部情報機器が取得不可である場合には、復元した映像信号を映像処理部１９に出力する。この場合には、画像処理しない。 As shown in FIG. 2, first, a digital signal compliant with the HDMI standard is input from the external input unit 31 to the HDMI signal processing unit 41 (step S1). The HDMI signal processing unit 41, which will be described in detail later with reference to different drawings, restores the input digital signal to a video signal and determines whether external device information can be acquired (step S2). If the external information device can be acquired, the external device information is acquired from the information included in the SPD packet and output to the image quality parameter control unit 42. When the external information device cannot be acquired, the restored video signal is output to the video processing unit 19. In this case, image processing is not performed.
　次に、ＨＤＤ、ＳＤカード等の固体メモリ、ＢＤ（ブルーレイディスク）、ＤＶＤ、ＣＤ等のディスク装置等の外部機器３０と、外部機器３０と外部入力部３１を介して接続されているＨＤＭＩ信号処理部４１と間におけるＨＤＭＩ信号に準拠したデジタル信号の処理について図３を参照して説明する。図３に示すＨＤＭＩ送信側は外部機器３０であり、ＨＤＭＩ受信側はテレビ受像機１０のＨＤＭＩ信号処理部４１である。図３に示す制御データにはＳＰＤデータが含まれている。このＳＰＤデータは、この図に示すようにパケット処理された後にエンコードされる。エンコードされたＳＰＤデータは、ＨＤＭＩケーブルを介してＨＤＭＩ信号処理部４１に送信されデコードされる。デコードされたＳＰＤデータは、再度パケット処理され、制御データに含まれるＳＰＤデータに戻される。 Next, HDMI signal processing connected to the external device 30 such as a solid-state memory such as an HDD or an SD card, or a disk device such as a BD (Blu-ray Disc), DVD, or CD, and the external device 30 via the external input unit 31. Processing of a digital signal compliant with the HDMI signal with the unit 41 will be described with reference to FIG. The HDMI transmission side illustrated in FIG. 3 is the external device 30, and the HDMI reception side is the HDMI signal processing unit 41 of the television receiver 10. The control data shown in FIG. 3 includes SPD data. The SPD data is encoded after packet processing as shown in FIG. The encoded SPD data is transmitted to the HDMI signal processing unit 41 via the HDMI cable and decoded. The decoded SPD data is packet-processed again and returned to the SPD data included in the control data.
　この過程において、ＨＤＭＩ信号処理部４１は、制御データに含まれるパケット処理されたＳＰＤデータから外部機器情報が取得可能であれば取得する。ＨＤＭＩ信号処理部４１は、上述したようにこの取得した外部機器情報を画質パラメータ制御部４２に送信する。また、図３に示すように、ＨＤＭＩ信号処理部４１は、入力されたデジタル信号を映像信号（映像データ）に復元して画質パラメータ制御部４２に送信する。 In this process, the HDMI signal processing unit 41 acquires external device information from the packet-processed SPD data included in the control data if it can be acquired. The HDMI signal processing unit 41 transmits the acquired external device information to the image quality parameter control unit 42 as described above. As shown in FIG. 3, the HDMI signal processing unit 41 restores the input digital signal to a video signal (video data) and transmits it to the image quality parameter control unit 42.
　画質パラメータ制御部４２は、ＨＤＭＩ信号処理部４１から入力したＳＰＤパケットに含まれる外部機器情報に応じて画像処理する。この画像処理について図４を参照して説明する。図４は、画質パラメータにおける設定項目を示す図である。画質パラメータ制御部４２は、ＳＰＤパケットに含まれるメーカー名、機種名、およびモデル名などの外部機器情報から、入力されたＳＰＤパケットに含まれる情報がゲーム、またはビデオカメラに含まれるフォトなどのうちのどのジャンルの情報であるかを判定する。 The image quality parameter control unit 42 performs image processing according to external device information included in the SPD packet input from the HDMI signal processing unit 41. This image processing will be described with reference to FIG. FIG. 4 is a diagram illustrating setting items in the image quality parameter. The image quality parameter control unit 42 selects information included in the input SPD packet from the external device information such as the manufacturer name, model name, and model name included in the SPD packet. Which genre of information is determined.
　画質パラメータ制御部４２は、入力された情報をゲームと判定した場合には、図４に示すように、ゲームに対応する画質パラメータとして設定されているＤＮＲ、ＩＰ変換、ＭＰＥＧ　ＮＲ、スケーリング、エンハンス、コントラスト、ティント・カラー、カラーマネジメント、ガンマ、およびデジャタといった項目を画質パラメータとして決定する（ステップＳ３）。次に、画質パラメータ制御部４２は、映像信号と決定した画質パラメータの情報を映像処理部１９に出力する。映像処理部１９は、受信した画質パラメータの情報に基づいて映像信号を処理する（ステップＳ４）。一例として図４に示す決定されたエンハンスに基づいて映像信号を処理する。同様に、決定したスケーリングおよびコントラストなどに基づいて映像信号を処理する。処理された映像信号は、上述したように、液晶表示装置２２において画面上に表示される（ステップＳ５）。 When the image quality parameter control unit 42 determines that the input information is a game, as shown in FIG. 4, the DNR, IP conversion, MPEG NR, scaling, enhancement, Items such as contrast, tint color, color management, gamma, and dejitter are determined as image quality parameters (step S3). Next, the image quality parameter control unit 42 outputs information on the video signal and the determined image quality parameter to the video processing unit 19. The video processing unit 19 processes the video signal based on the received image quality parameter information (step S4). As an example, the video signal is processed based on the determined enhancement shown in FIG. Similarly, the video signal is processed based on the determined scaling and contrast. The processed video signal is displayed on the screen in the liquid crystal display device 22 as described above (step S5).
　以上説明したように、映像表示装置１においては、ＳＰＤパケットに含まれる情報に応じて、画質パラメータを決定し、決定した画質パラメータに基づいて前記映像信号を処理する。このため、ＣＥＣ制御ラインを用いることなく、画像処理できる。 As described above, the video display device 1 determines the image quality parameter according to the information included in the SPD packet, and processes the video signal based on the determined image quality parameter. For this reason, image processing can be performed without using the CEC control line.
　以上の説明では、特に、テレビ受像機を例にして述べているが、その他にも、テレビを視聴可能とした携帯機器、例えば、携帯電話、カーナビゲーションシステム、携帯ゲーム端末機等においてテレビを受信する場合にも本願の発明に従った表示方法を適用できることは明らかである。 In the above description, the television receiver is particularly described as an example. However, in addition to this, the television is received by a portable device capable of viewing the television, for example, a mobile phone, a car navigation system, a portable game terminal, or the like. Obviously, the display method according to the invention of the present application can also be applied.
