Description

表示装置、テレビジョン受像機、プログラム及び記録媒体Display device, television receiver, program, and recording medium
　本発明は表示装置、テレビジョン受像機、プログラム及び記録媒体に関し、より詳細には、識別用画像が含まれる映像を表示する表示装置、テレビジョン受像機、プログラム及び記録媒体に関する。 The present invention relates to a display device, a television receiver, a program, and a recording medium. More specifically, the present invention relates to a display device, a television receiver, a program, and a recording medium that display an image including an identification image.
　近年、テレビの放送番組では、ＱＲ（Ｑｕｉｃｋ　Ｒｅｓｐｏｎｃｅ）コード（登録商標）等の二次元コードが使用されることがある。そのような場合、ユーザはテレビの表示画面に表示されたＱＲコード（登録商標）をスマートフォン等で読み取り、ＱＲコード（登録商標）に対応するＵＲＬ（Ｕｎｉｆｏｒｍ　Ｒｅｓｏｕｒｃｅ　Ｌｏｃａｔｏｒ）のサイトにアクセスすれば、放送番組に関する情報又は商品を得ることができる。 In recent years, a two-dimensional code such as a QR (Quick Response) code (registered trademark) is sometimes used in a television broadcast program. In such a case, if the user reads the QR code (registered trademark) displayed on the display screen of the TV with a smartphone or the like, and accesses a URL (Uniform Resource Locator) site corresponding to the QR code (registered trademark), the broadcast is performed. Information or products related to the program can be obtained.
　最近では、このような二次元コードを使用した放送番組を視聴する際の工夫がなされている。例えば、特許文献１には、放送映像から二次元コードを認識して、当該ニ次元コードをＵＲＬに変換し、ＷＥＢブラウザによりＵＲＬにアクセスしてＷＥＢページを表示する表示装置が開示されている。 Recently, a device for viewing a broadcast program using such a two-dimensional code has been devised. For example, Patent Document 1 discloses a display device that recognizes a two-dimensional code from a broadcast video, converts the two-dimensional code into a URL, accesses the URL by a WEB browser, and displays a WEB page.
日本国公開特許公報「特開２０１５－３２０３９号公報（２０１５年２月１６日公開）」Japanese Patent Publication “Japanese Patent Laid-Open No. 2015-32039 (published on February 16, 2015)”
　ところで、最近では、放送番組を視聴しながら、同一画面上で別の放送番組を見たいという要望から、子画面を用いて親画面上に他の放送番組の映像を表示したり、二画面表示を用いて２つの放送番組の映像を表示したりする技術が提案されている。そうした場合、表示している映像のいずれかに二次元コード等の識別用画像が含まれていると、子画面表示又は二画面表示に応じて識別用画像も縮小して表示されることになる。 By the way, recently, from the desire to watch another broadcast program on the same screen while watching the broadcast program, the video of another broadcast program is displayed on the parent screen using a sub-screen, or a two-screen display. There has been proposed a technique for displaying videos of two broadcast programs by using. In such a case, if an identification image such as a two-dimensional code is included in any of the displayed images, the identification image is also reduced and displayed in accordance with the sub-screen display or the two-screen display. .
　特許文献１に開示されているように、表示装置上で識別用画像に対応するＵＲＬにアクセスするのではなく、ユーザのスマートフォン等で識別用画像に対応するＵＲＬにアクセスしたい場合には、縮小して表示された識別用画像をスマートフォン等で読み取る必要がある。しかしながら、縮尺によっては縮小した識別用画像をスマートフォン等で読み込みできなくなってしまうという第１の問題がある。 As disclosed in Patent Document 1, instead of accessing the URL corresponding to the identification image on the display device, if the user wants to access the URL corresponding to the identification image with a smartphone or the like, the URL is reduced. It is necessary to read the identification image displayed by the smartphone or the like. However, depending on the scale, there is a first problem that a reduced identification image cannot be read by a smartphone or the like.
　上記第１の問題は、表示パネルのサイズが小さい場合にも起こり得る。表示パネルのサイズが小さいと、表示パネルのサイズに応じて映像を縮小して表示することになるので、縮尺によっては縮小した識別用画像をスマートフォン等で読み込む（識別する）ことができなくなってしまう可能性がある。 The first problem can also occur when the size of the display panel is small. If the size of the display panel is small, the video will be reduced and displayed according to the size of the display panel, and depending on the scale, the reduced identification image cannot be read (identified) by a smartphone or the like. there is a possibility.

Even so, an object of the present invention is to provide a display device, a television receiver, a program, and a recording medium that can identify the identification image without any problem.
　また、ニ次元コード等の識別用画像によって指定されるＵＲＬのサイトには、一定期間のみ開設されているものがある。そうした場合、放送番組を視聴するタイミングによっては、サイトの有効期限が切れているためにサイトにアクセスできず、ユーザが混乱する可能性があるという第２の問題がある。また、放送番組を視聴するタイミングによっては、表示された識別用画像から得られる情報がもはやユーザにとって無用なことがある。 Also, some URL sites designated by identification images such as two-dimensional codes are open only for a certain period. In such a case, depending on the timing of viewing the broadcast program, there is a second problem that the site cannot be accessed because the expiration date of the site has expired, and the user may be confused. In addition, depending on the timing of viewing a broadcast program, information obtained from the displayed identification image may no longer be useful to the user.
　本発明の第９～１９の態様は、上記第２の問題点に鑑みてなされたものであり、その目的は、映像に含まれる無効な識別用画像によってユーザが混乱するのを防止できる表示装置、テレビジョン受像機、プログラム及び記録媒体を提供することにある。 The ninth to nineteenth aspects of the present invention have been made in view of the second problem, and an object thereof is a display device capable of preventing a user from being confused by an invalid identification image included in a video.

　本実施形態に係る表示装置は、テレビ放送映像等の映像を表示するものである。本実施形態に係る表示装置は、例えばテレビジョン受像機、パーソナルコンピュータ、又はテレビジョン機能付きパーソナルコンピュータ等の表示装置として実現できる。以下では、本実施形態に係る表示装置の詳細な構成について、図１に基づいて説明する。図１は、本実施形態に係る表示装置１の構成を示すブロック図である。 [First Embodiment]
(Configuration of display device)
The display device according to the present embodiment displays an image such as a television broadcast image. The display device according to the present embodiment can be realized as a display device such as a television receiver, a personal computer, or a personal computer with a television function. Below, the detailed structure of the display apparatus which concerns on this embodiment is demonstrated based on FIG. FIG. 1 is a block diagram illustrating a configuration of a display device 1 according to the present embodiment.
　図１に示すように、表示装置１は、制御部１１、メモリ１７、表示部１８、チューナ部１９、外部通信部２０及び外部機器接続部２１を有している。 1, the display device 1 includes a control unit 11, a memory 17, a display unit 18, a tuner unit 19, an external communication unit 20, and an external device connection unit 21.
　制御部１１は、表示装置１の各部の動作及び処理を制御するものであり、表示処理部１４、検出部１５及び判定部１６を有している。 The control unit 11 controls the operation and processing of each unit of the display device 1, and includes a display processing unit 14, a detection unit 15, and a determination unit 16.
　表示処理部１４は、映像内に含まれている識別用画像を取得する取得部（図示せず）を備えている。表示処理部１４は、取得した識別用画像を、映像と共に表示部１８の表示画面に表示する。 The display processing unit 14 includes an acquisition unit (not shown) that acquires an identification image included in the video. The display processing unit 14 displays the acquired identification image together with the video on the display screen of the display unit 18.
　表示処理部１４は、後述するチューナ部１９が受信した放送波から取得したテレビ放送映像、又は後述する外部通信部２０が通信ネットワーク２３を介して取得した（例えば、ストリーミング配信された）コンテンツ映像等、表示処理部１４に供給された映像を表示部１８に表示させるための処理を行う。表示処理部１４は、後述する判定部１６からの指示に基づき、映像内の識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示部１８に表示させる処理も行う。 The display processing unit 14 is a television broadcast video acquired from a broadcast wave received by a tuner unit 19 described later, or a content video acquired (for example, streamed) by the external communication unit 20 described later via the communication network 23. Then, a process for displaying the video supplied to the display processing unit 14 on the display unit 18 is performed. Based on an instruction from the determination unit 16 to be described later, the display processing unit 14 determines whether the size of the identification image when the identification image in the video is displayed on the display screen or the size of the constituent unit constituting the identification image is predetermined. A process of displaying the identification image on the display unit 18 is also performed so as not to be smaller than the size of.
　なお、本明細書において、識別用画像とは、バーコード等の一次元コード、ＱＲコード（登録商標）等の二次元コード、及び電子透かし等、情報が埋め込まれた画像を意味する。なお、電子透かしとは、動画像及び静止画像等のコンテンツに埋め込まれた情報であり、ユーザが視認できないものである。また、構成単位とは、例えばバーコードの場合はバー（棒）であり、ＱＲコード（登録商標）の場合はセルである。 In this specification, the identification image means an image in which information such as a one-dimensional code such as a barcode, a two-dimensional code such as a QR code (registered trademark), and a digital watermark is embedded. The digital watermark is information embedded in content such as a moving image and a still image and cannot be visually recognized by the user. Further, the structural unit is, for example, a bar (bar) in the case of a barcode, and a cell in the case of a QR code (registered trademark).
　検出部１５は、表示部１８の表示画面に表示するための映像内に含まれている識別用画像を検出する。具体的には、検出部１５は、表示処理部１４が表示部１８に表示させるための映像を取得して、画像認識処理により映像内に識別用画像が含まれているか否かを検出する。より具体的には、検出部１５は、表示処理部１４が表示部１８に表示させるための映像をフレームごとに解析し、フレーム画像に含まれている識別用画像を認識する。 The detection unit 15 detects an identification image included in the video to be displayed on the display screen of the display unit 18. Specifically, the detection unit 15 acquires a video to be displayed on the display unit 18 by the display processing unit 14 and detects whether or not an identification image is included in the video by image recognition processing. More specifically, the detection unit 15 analyzes a video for the display processing unit 14 to display on the display unit 18 for each frame, and recognizes an identification image included in the frame image.
　なお、検出部１５による検出方法は画像認識処理に限定されない。例えば、放送波から取得したメタ情報には、テレビ放送映像に含まれる識別用画像の情報が含まれている場合がある。この場合、検出部１５は、放送波から取得したメタ情報を参照して、映像内に識別用画像が含まれているか否かを検出することができる。 In addition, the detection method by the detection unit 15 is not limited to the image recognition process. For example, the meta information acquired from the broadcast wave may include identification image information included in the television broadcast video. In this case, the detection unit 15 can detect whether or not an identification image is included in the video with reference to the meta information acquired from the broadcast wave.
　検出部１５は、映像内に識別用画像が含まれていることを検出すると、当該識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回るか否かを判定するように判定部１６に指示する。 When the detection unit 15 detects that the image for identification is included in the video, the size of the image for identification when the image for identification is displayed on the display screen or the size of the structural unit constituting the image for identification is determined. Then, the determination unit 16 is instructed to determine whether or not the size falls below a predetermined size.
　判定部１６は、検出部１５が検出した識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズを算出し、算出したサイズが所定の大きさを下回るか否かを判定する。判定部１６による具体的な判定方法については、後述する。判定部１６は、算出したサイズが所定の大きさを下回ると判定すると、当該識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示するよう表示処理部１４に指示する。 The determination unit 16 calculates the size of the identification image when the identification image detected by the detection unit 15 is displayed on the display screen or the size of the constituent unit constituting the identification image, and the calculated size is a predetermined size. It is determined whether or not it falls below. A specific determination method by the determination unit 16 will be described later. If the determination unit 16 determines that the calculated size is less than the predetermined size, the size of the identification image when the identification image is displayed on the display screen or the size of the constituent unit constituting the identification image is predetermined. The display processing unit 14 is instructed to display the identification image so as not to be less than the size of.
　なお、検出部１５が検出した識別用画像の映像内における位置情報は、判定部１６を介して表示処理部１４に送られる。そのため、表示処理部１４は、当該位置情報に基づき識別用画像を特定し、当該識別用画像のサイズ又は識別用画像を構成する構成単位のサイズを調整して表示部１８に表示させる。 Note that the position information in the video of the identification image detected by the detection unit 15 is sent to the display processing unit 14 via the determination unit 16. Therefore, the display processing unit 14 specifies the identification image based on the position information, and adjusts the size of the identification image or the size of the constituent unit constituting the identification image to display on the display unit 18.

　（判定部による判定）
　上述したように、判定部１６は、検出部１５が検出した識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズを算出し、算出したサイズが所定の大きさを下回るか否かを判定する。この判定方法について、図２及び図３を参照して以下に説明する。図２は、表示画面に表示するための映像の一例を示しており、図３は、表示画面に映像を表示する場合の表示画面の一表示例を示している。これらの図では、識別用画像としてＱＲコード（登録商標）が示されている。 (Judgment by judgment part)
As described above, the determination unit 16 calculates the size of the identification image in the case where the identification image detected by the detection unit 15 is displayed on the display screen or the size of the constituent unit constituting the identification image, and calculates the calculated size. Is determined to be less than a predetermined size. This determination method will be described below with reference to FIGS. FIG. 2 shows an example of an image to be displayed on the display screen, and FIG. 3 shows an example of the display screen when an image is displayed on the display screen. In these drawings, a QR code (registered trademark) is shown as an identification image.
　＜画像サイズの判定＞
　まず、識別用画像を表示画面に表示する場合の識別用画像のサイズが所定の大きさを下回るか否かを判定する方法について説明する。 <Determination of image size>
First, a method for determining whether or not the size of the identification image when displaying the identification image on the display screen is less than a predetermined size will be described.
　判定部１６は、以下の式（１）及び（２）に基づき、表示するための映像において、識別用画像が占める割合を算出する。ＷＲｑｒは、表示するための映像において、識別用画像の横のサイズが占める割合であり、ＨＲｑｒは、表示するための映像において、識別用画像の縦のサイズが占める割合であり、図２に示す映像において、識別用画像５０ａが占める割合に相当する。 The determination unit 16 calculates the ratio of the identification image in the video to be displayed based on the following formulas (1) and (2). WRqr is the ratio of the horizontal size of the identification image in the video to be displayed, and HRqr is the ratio of the vertical size of the identification image in the video to be displayed, as shown in FIG. This corresponds to the ratio of the identification image 50a in the video.
　ＷＲｑｒ＝Ｗｑｒ÷Ｗ・・・（１）
　ＨＲｑｒ＝Ｈｑｒ÷Ｈ・・・（２）
　ここで、Ｗは、表示するための映像の横のサイズ（ピクセル）であり、Ｈは、表示するための映像の縦のサイズ（ピクセル）であり、図２に示す映像のサイズに相当する。Ｗ，Ｈは、データ放送等の規格で定められている値である。
Ｗｑｒは、識別用画像の横の表示サイズ（ピクセル）であり、Ｈｑｒは、識別用画像の縦の表示サイズ（ピクセル）であり、図２に示す映像内の識別用画像５０ａのサイズに相当する。Ｗｑｒ，Ｈｑｒは、Ｗ，Ｈのサイズの映像におけるサイズであり、放送局等から指定されているものである。 WRqr = Wqr / W (1)
HRqr = Hqr ÷ H (2)
Here, W is the horizontal size (pixel) of the video to be displayed, and H is the vertical size (pixel) of the video to be displayed, which corresponds to the size of the video shown in FIG. W and H are values defined by standards such as data broadcasting.
Wqr is the horizontal display size (pixel) of the identification image, and Hqr is the vertical display size (pixel) of the identification image, which corresponds to the size of the identification image 50a in the video shown in FIG. . Wqr and Hqr are the sizes in the video of W and H sizes, and are designated by broadcasting stations or the like.
　なお、識別用画像がデータ放送から取得した映像内に含まれている場合、Ｗ，Ｈは、データ放送の規格で定められており、判定部１６は、Ｗｑｒ，Ｈｑｒをメタ情報から取得し、これらからＷＲｑｒ，ＨＲｑｒを算出すればよい。また、識別用画像が画像として映像内に含まれている場合、判定部１６は、Ｗ，Ｈを当該映像の符号化データから取得し、Ｗｑｒ，Ｈｑｒを映像の画像認識で取得し、これらからＷＲｑｒ，ＨＲｑｒを算出すればよい。 When the identification image is included in the video acquired from the data broadcast, W and H are defined by the data broadcast standard, and the determination unit 16 acquires Wqr and Hqr from the meta information, WRqr and HRqr may be calculated from these. When the identification image is included in the video as an image, the determination unit 16 acquires W and H from the encoded data of the video, acquires Wqr and Hqr by video image recognition, and from these What is necessary is just to calculate WRqr and HRqr.
　続いて、判定部１６は、以下の式（３）～（６）に基づき、識別用画像を表示画面に表示する場合の識別用画像のサイズを算出する。Ｓｗｐは、識別用画像の横のサイズ（ピクセル）であり、Ｓｈｐは、識別用画像の縦のサイズ（ピクセル）である。また、Ｓｗｉは、識別用画像の横のサイズ（センチメートル）であり、Ｓｈｉは、識別用画像の縦のサイズ（センチメートル）である。Ｓｗｐ，Ｓｈｐ，Ｓｗｉ，Ｓｈｉは、図３に示す表示画面４０に表示された識別用画像５０ｂのサイズに相当する。 Subsequently, the determination unit 16 calculates the size of the identification image when the identification image is displayed on the display screen based on the following equations (3) to (6). Swp is the horizontal size (pixels) of the identification image, and Shp is the vertical size (pixels) of the identification image. Swi is the horizontal size (centimeter) of the identification image, and Shi is the vertical size (centimeter) of the identification image. Swp, Shp, Swi, and Shi correspond to the size of the image for identification 50b displayed on the display screen 40 shown in FIG.
　Ｓｗｐ＝ＲＳ×Ｗｐ×ＷＲｑｒ・・・（３）
　Ｓｈｐ＝ＲＳ×Ｈｐ×ＨＲｑｒ・・・（４）
　Ｓｗｉ＝ＲＳ×Ｗｉ×ＷＲｑｒ・・・（５）
　Ｓｈｉ＝ＲＳ×Ｈｉ×ＨＲｑｒ・・・（６）
Ｗｐは、表示画面の横の解像度（ピクセル）であり、Ｈｐは、表示画面の縦の解像度（ピクセル）であり、図３に示す表示装置１の表示画面の解像度に相当する。また、Ｗｉは、表示画面の横のサイズ（センチメートル）であり、Ｈｉは、表示画面の縦のサイズ（センチメートル）であり、図３に示す表示装置１の表示画面のサイズに相当する。
ＲＳは、映像を一画面表示する場合に対する倍率である。例えば、二画面表示をしている場合は、一画面表示する場合に対して映像を半分の大きさに縮小して表示するため、ＲＳ＝０．５となる。 Swp = RS × Wp × WRqr (3)
Shp = RS × Hp × HRqr (4)
Swi = RS × Wi × WRqr (5)
Shi = RS × Hi × HRqr (6)
Wp is the horizontal resolution (pixels) of the display screen, and Hp is the vertical resolution (pixels) of the display screen, which corresponds to the display screen resolution of the display device 1 shown in FIG. Moreover, Wi is the horizontal size (centimeter) of the display screen, and Hi is the vertical size (centimeter) of the display screen, which corresponds to the size of the display screen of the display device 1 shown in FIG.
RS is a magnification with respect to the case where video is displayed on a single screen. For example, in the case of two-screen display, the video is reduced to half the size of the single-screen display, so RS = 0.5.
　判定部１６は、Ｓｗｐ及びＳｈｐ、ならびにＳｗｉ及びＳｈｉのそれぞれが、それぞれに対応する所定の大きさを下回るか否かを判定する。所定の大きさとは、表示画面上に表示された識別用画像をスマートフォン等で読み込む（識別する）ために必要な識別用画像のサイズの最小値である。この最小値は、予め定められており、判定部１６は、Ｓｗｐが、表示画面上に表示された識別用画像を識別するために必要な識別用画像のサイズ（ピクセル）の最小値ＭＩＮｗｐを下回るか否かを判定すると共に、Ｓｈｐが、表示画面上に表示された識別用画像を識別するために必要な識別用画像のサイズ（ピクセル）の最小値ＭＩＮｈｐを下回るか否かを判定する。 The determination unit 16 determines whether each of Swp and Shp, and Swi and Shi is less than a predetermined size corresponding to each. The predetermined size is a minimum value of the size of the identification image necessary for reading (identifying) the identification image displayed on the display screen with a smartphone or the like. This minimum value is determined in advance, and the determination unit 16 has Swp below the minimum value MINwp of the size (pixel) of the image for identification necessary for identifying the image for identification displayed on the display screen. It is determined whether or not Shp is below a minimum value MINhp of the size (pixels) of the identification image necessary for identifying the identification image displayed on the display screen.
　同時に、判定部１６は、Ｓｗｉが、表示画面上に表示された識別用画像を識別するために必要な識別用画像のサイズ（センチメートル）の最小値ＭＩＮｗｉを下回るか否かを判定すると共に、Ｓｈｉが、表示画面上に表示された識別用画像を識別するために必要な識別用画像のサイズ（センチメートル）の最小値ＭＩＮｈｉを下回るか否かを判定する。 At the same time, the determination unit 16 determines whether or not Swi is smaller than the minimum value MINwi of the size (centimeter) of the identification image necessary for identifying the identification image displayed on the display screen. It is determined whether Shi is below the minimum value MINhi of the size (centimeter) of the identification image necessary for identifying the identification image displayed on the display screen.
　判定部１６は、Ｓｗｐ、Ｓｈｐ、Ｓｗｉ及びＳｈｉのうち、それぞれに対応する所定の大きさを下回るものが１つでもあると、識別用画像を表示画面に表示する場合の識別用画像のサイズが、所定の大きさを下回らないように識別用画像を表示するよう表示処理部１４に指示する。 The determination unit 16 determines that the size of the identification image when the identification image is displayed on the display screen is any one of Swp, Shp, Swi, and Shi that is smaller than a predetermined size corresponding to each of them. The display processing unit 14 is instructed to display the identification image so as not to fall below a predetermined size.
　＜画像の構成単位のサイズの判定＞
　次に、識別用画像を表示画面に表示する場合の識別用画像を構成する構成単位のサイズが所定の大きさを下回るか否かを判定する方法について説明する。 <Determination of image unit size>
Next, a method for determining whether or not the size of the structural unit constituting the identification image when the identification image is displayed on the display screen will be described.
　判定部１６は、式（１）及び（２）に基づき、表示するための映像において、識別用画像が占める割合を算出した後、以下の式（７）～（１０）に基づき、識別用画像を表示画面に表示する場合の識別用画像を構成する構成単位のサイズを算出する。Ｕｗｐは、識別用画像を構成する構成単位の横のサイズ（ピクセル）であり、Ｕｈｐは、識別用画像を構成する構成単位の縦のサイズ（ピクセル）である。また、Ｕｗｉは、識別用画像を構成する構成単位の横のサイズ（センチメートル）であり、Ｕｈｉは、識別用画像を構成する構成単位の縦のサイズ（センチメートル）である。Ｕｗｐ，Ｕｈｐ，Ｕｗｉ，Ｕｈｉは、図３に示す表示画面４０に表示された識別用画像５０ｂを構成する構成単位のサイズに相当する。 The determination unit 16 calculates the ratio of the identification image in the video to be displayed based on the expressions (1) and (2), and then determines the identification image based on the following expressions (7) to (10). Is calculated on the display screen. The size of the constituent unit constituting the identification image is calculated. Uwp is the horizontal size (pixel) of the structural unit that constitutes the identification image, and Uhp is the vertical size (pixel) of the structural unit that constitutes the identification image. Uwi is the horizontal size (centimeter) of the constituent unit constituting the identification image, and Uhi is the vertical size (centimeter) of the constituent unit constituting the identification image. Uwp, Uhp, Uwi, and Uhi correspond to the sizes of the constituent units constituting the identification image 50b displayed on the display screen 40 shown in FIG.
　Ｕｗｐ＝ＲＳ×Ｗｐ×ＷＲｑｒ÷Ｗｕｑｒ・・・（７）
　Ｕｈｐ＝ＲＳ×Ｈｐ×ＨＲｑｒ÷Ｈｕｑｒ・・・（８）
　Ｕｗｉ＝ＲＳ×Ｗｉ×ＷＲｑｒ÷Ｗｕｑｒ・・・（９）
　Ｕｈｉ＝ＲＳ×Ｈｉ×ＨＲｑｒ÷Ｈｕｑｒ・・・（１０）
　ここで、Ｗｕｑｒは、識別用画像を構成する構成単位の横方向の数であり、Ｈｕｑｒは、識別用画像を構成する構成単位の縦方向の数であり、図２に示す映像内の識別用画像５０ａを構成する構成単位の数に相当する。Ｗｕｑｒ，Ｈｕｑｒは、メタ情報から識別用画像に関する情報を取得し、当該識別用画像を構成する構成単位の数を特定してもよいし、識別用画像が含まれる映像を取得して、画像認識処理により当該識別用画像を構成する構成単位の数を特定してもよい。 Uwp = RS × Wp × WRqr ÷ Wuqr (7)
Uhp = RS × Hp × HRqr ÷ Huqr (8)
Uwi = RS × Wi × WRqr ÷ Wuqr (9)
Uhi = RS × Hi × HRqr ÷ Huqr (10)
Here, Wuqr is the number of structural units constituting the identification image in the horizontal direction, Huqr is the number of structural units constituting the identification image in the vertical direction, and is used for identification in the video shown in FIG. This corresponds to the number of structural units constituting the image 50a. Wuqr and Huqr may acquire information related to the image for identification from the meta information, specify the number of structural units constituting the image for identification, acquire video including the image for identification, and perform image recognition You may identify the number of the structural units which comprise the said image for identification by a process.
　判定部１６は、Ｕｗｐ及びＵｈｐ、あるいはＵｗｉ及びＵｈｉそれぞれが、それぞれに対応する所定の大きさを下回るか否かを判定する。所定の大きさとは、表示画面上に表示された識別用画像をスマートフォン等で読み込む（識別する）ために必要な識別用画像を構成する構成単位のサイズの最小値である。この最小値は、予め定められており、判定部１６は、Ｕｗｐが、表示画面上に表示された識別用画像を識別するために必要な識別用画像を構成する構成単位のサイズ（ピクセル）の最小値ＭＩＮｕｗｐを下回るか否かを判定すると共に、Ｕｈｐが、表示画面上に表示された識別用画像を識別するために必要な識別用画像を構成する構成単位のサイズ（ピクセル）の最小値ＭＩＮｕｈｐを下回るか否かを判定する。 The determination unit 16 determines whether each of Uwp and Uhp, or Uwi and Uhi is less than a predetermined size corresponding to each. The predetermined size is the minimum value of the size of the structural unit constituting the identification image necessary for reading (identifying) the identification image displayed on the display screen with a smartphone or the like. This minimum value is determined in advance, and the determination unit 16 determines the size (pixel) of the constituent unit that constitutes the identification image necessary for Uwp to identify the identification image displayed on the display screen. It is determined whether or not the minimum value MINupp is below, and Uhp is the minimum value MINupp of the size (pixel) of the constituent unit constituting the identification image necessary for identifying the identification image displayed on the display screen. It is determined whether or not it falls below.
　同時に、判定部１６は、Ｕｗｉが、表示画面上に表示された識別用画像を識別するために必要な識別用画像を構成する構成単位のサイズ（センチメートル）の最小値ＭＩＮｕｗｉを下回るか否かを判定すると共に、Ｕｈｉが、表示画面上に表示された識別用画像を識別するために必要な識別用画像を構成する構成単位のサイズ（センチメートル）の最小値ＭＩＮｕｈｉを下回るか否かを判定する。 At the same time, the determination unit 16 determines whether or not Uwi is smaller than the minimum value MINuwi of the size (centimeter) of the constituent unit constituting the identification image necessary for identifying the identification image displayed on the display screen. And whether or not Uhi is smaller than the minimum value MINuhi of the size (centimeter) of the structural unit constituting the identification image necessary for identifying the identification image displayed on the display screen To do.
　判定部１６は、Ｕｗｐ、Ｕｈｐ、Ｕｗｉ及びＵｈｉのうち、それぞれに対応する所定の大きさを下回るものが１つでもあると、識別用画像を表示画面に表示する場合の識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示するよう表示処理部１４に指示する。 The determination unit 16 configures an identification image when an identification image is displayed on the display screen when at least one of Uwp, Uhp, Uwi, and Uhi is smaller than a predetermined size corresponding thereto. The display processing unit 14 is instructed to display the identification image so that the size of the structural unit does not fall below a predetermined size.
　（表示処理部による調整）
　表示処理部１４は、判定部１６からの指示を受け、映像内の識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を調整して表示部１８に表示させる処理を行う。この処理について、図４を参照して以下に説明する。図４は、識別用画像を調整して表示画面に表示する場合の表示画面の一表示例を示している。 (Adjustment by the display processing unit)
The display processing unit 14 receives an instruction from the determination unit 16, and the size of the identification image when the identification image in the video is displayed on the display screen or the size of the constituent unit constituting the identification image is a predetermined size. The identification image is adjusted so as not to be less than that and displayed on the display unit 18. This process will be described below with reference to FIG. FIG. 4 shows a display example of the display screen when the identification image is adjusted and displayed on the display screen.
　＜画像のサイズに基づく調整＞
　まず、識別用画像を表示画面に表示する場合の識別用画像のサイズが所定の大きさを下回らないように識別用画像を表示する処理について説明する。 <Adjustment based on image size>
First, a process for displaying an identification image so that the size of the identification image when the identification image is displayed on the display screen does not fall below a predetermined size will be described.
　表示処理部１４は、以下の式（１１）～（１４）を満たす調整値を算出する。Ｃｗｐ，Ｃｈｐ，Ｃｗｉ，Ｃｈｉは、それぞれ識別用画像を表示画面に表示する場合の識別用画像のサイズが所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する倍率（調整値）である。Ｃｗｐ，Ｃｗｉは、それぞれＳｗｐ，Ｓｗｉがそれぞれに対応する所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する横方向の倍率であり、Ｃｈｐ，Ｃｈｉは、それぞれＳｗｉ，Ｓｈｉがそれぞれに対応する所定の大きさを下回らないように必要な、映像内の識別用画像に対する縦方向の倍率である。 The display processing unit 14 calculates an adjustment value that satisfies the following expressions (11) to (14). Cwp, Chp, Cwi, and Chi are magnifications with respect to the identification image in the video that are necessary to prevent the size of the identification image from being smaller than a predetermined size when the identification image is displayed on the display screen. (Adjustment value). Cwp and Cwi are magnifications in the horizontal direction with respect to the identification image in the video, which are necessary to prevent each of Swp and Swi from falling below a predetermined size corresponding to each, and Chp and Chi are respectively Swi. , Shi is a magnification in the vertical direction with respect to the image for identification in the video, which is necessary so that it does not fall below a predetermined size corresponding to each.
　ＭＩＮｗｐ＝Ｃｗｐ×Ｓｗｐ・・・（１１）
　ＭＩＮｈｐ＝Ｃｈｐ×Ｓｈｐ・・・（１２）
　ＭＩＮｗｉ＝Ｃｗｉ×Ｓｗｉ・・・（１３）
　ＭＩＮｈｉ＝Ｃｈｉ×Ｓｈｉ・・・（１４）
　表示処理部１４は、Ｃｗｐ，Ｃｈｐ，Ｃｗｉ，Ｃｈｉのうち最も大きい値の調整値を特定し、映像を表示部１８に表示させる際に、映像内の識別用画像を当該調整値だけ拡大したものを表示部１８に表示させる。より具体的には、表示処理部１４は、映像内の識別用画像を当該調整値だけ拡大したものをＲＳの分だけ縮小して表示部１８に表示させる。換言すれば、表示処理部１４は、映像を表示部１８に表示させる際に、映像内の識別用画像を表示画面に表示する場合のサイズが、調整値（Ｃｗｐ，Ｃｈｐ，Ｃｗｉ，Ｃｈｉのうち最も大きい値）×ＲＳ倍となるように識別用画像を表示部１８に表示させる。 MINwp = Cwp × Swp (11)
MINhp = Chp × Shp (12)
MINwi = Cwi × Swi (13)
MINhi = Chi × Shi (14)
The display processing unit 14 specifies an adjustment value having the largest value among Cwp, Chp, Cwi, and Chi, and enlarges the identification image in the video by the adjustment value when the video is displayed on the display unit 18. Is displayed on the display unit 18. More specifically, the display processing unit 14 enlarges the identification image in the video by the adjustment value and reduces the image for the RS to display on the display unit 18. In other words, when the display processing unit 14 displays the video on the display unit 18, the size when the identification image in the video is displayed on the display screen is the adjustment value (Cwp, Chp, Cwi, Chi). The image for identification is displayed on the display unit 18 so that the largest value) × RS times.
　このため、ＲＳの値によっては表示する識別用画像のサイズが、映像を全画面表示する場合の識別用画像のサイズよりも縮小されることもあるが、当該識別用画像のサイズは、所定の大きさを下回らないように表示されることになる。 For this reason, depending on the value of RS, the size of the identification image to be displayed may be smaller than the size of the identification image in the case of displaying the video in full screen, but the size of the identification image is a predetermined value. It will be displayed so as not to be smaller than the size.
　＜画像の構成単位のサイズに基づく調整＞
　次に、識別用画像を表示画面に表示する場合の識別用画像を構成する構成単位のサイズが所定の大きさを下回らないように識別用画像を表示する処理について説明する。 <Adjustment based on image unit size>
Next, a process for displaying the identification image so that the size of the structural unit constituting the identification image when the identification image is displayed on the display screen is not less than a predetermined size will be described.
　表示処理部１４は、以下の式（１５）～（１８）を満たす調整値を算出する。Ｃｕｗｐ，Ｃｕｈｐ，Ｃｕｗｉ，Ｃｕｈｉは、それぞれ識別用画像を表示画面に表示する場合の識別用画像を構成する構成単位のサイズが所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する倍率（調整値）である。Ｃｕｗｐ，Ｃｕｗｉは、それぞれＵｗｐ，Ｕｈｐがそれぞれに対応する所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する横方向の倍率であり、Ｃｕｈｐ，Ｃｕｈｉは、それぞれＵｈｐ，Ｕｈｉがそれぞれに対応する所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する縦方向の倍率である。 The display processing unit 14 calculates an adjustment value that satisfies the following equations (15) to (18). Cuwp, Cuhp, Cuwi, and Cuhi are required to prevent the size of the constituent unit constituting the identification image from being less than a predetermined size when the identification image is displayed on the display screen. This is the magnification (adjustment value) for the identification image. Cuwp and Cuwi are horizontal magnifications for the identification image in the video, which are necessary to prevent Uwp and Uhp from falling below a predetermined size corresponding to each, and Cuhp and Cuhi are respectively Uhp. , Uhi is a vertical magnification with respect to the identification image in the video, which is necessary so that Uhi does not fall below a predetermined size corresponding to each.
　ＭＩＮｕｗｐ＝Ｃｕｗｐ×Ｕｗｐ・・・（１５）
　ＭＩＮｕｈｐ＝Ｃｕｈｐ×Ｕｈｐ・・・（１６）
　ＭＩＮｕｗｉ＝Ｃｕｗｉ×Ｕｗｉ・・・（１７）
　ＭＩＮｕｈｉ＝Ｃｕｈｉ×Ｕｈｉ・・・（１８）
　表示処理部１４は、Ｃｕｗｐ，Ｃｕｈｐ，Ｃｕｗｉ，Ｃｕｈｉのうち最も大きい値の調整値を特定し、映像を表示部１８に表示させる際に、映像内の識別用画像を当該調整値だけ拡大したものを表示部１８に表示させる。より具体的には、表示処理部１４は、映像内の識別用画像を当該調整値だけ拡大したものをＲＳの分だけ縮小して表示部１８に表示させる。換言すれば、表示処理部１４は、映像を表示部１８に表示させる際に、識別用画像のサイズが、調整値（Ｃｕｗｐ，Ｃｕｈｐ，Ｃｕｗｉ，Ｃｕｈｉのうち最も大きい値）×ＲＳ倍となるように識別用画像を表示部１８に表示させる。 MINuwp = Cuwp × Uwp (15)
MINuhp = Cuhp × Uhp (16)
MINuwi = Cuwi × Uwi (17)
MINuhi = Cuhi × Uhi (18)
The display processing unit 14 specifies the largest adjustment value among Cuwp, Cuhp, Cuwi, and Cuhi, and enlarges the identification image in the video by the adjustment value when the video is displayed on the display unit 18. Is displayed on the display unit 18. More specifically, the display processing unit 14 enlarges the identification image in the video by the adjustment value and reduces the image for the RS to display on the display unit 18. In other words, when the display processing unit 14 displays the video on the display unit 18, the size of the image for identification becomes an adjustment value (the largest value among Cuwp, Cuhp, Cuwi, Cuhi) × RS times. The image for identification is displayed on the display unit 18.
　このため、ＲＳの値によっては表示する識別用画像のサイズが、映像を全画面表示する場合の識別用画像のサイズよりも縮小されることもあるが、当該識別用画像を構成する構成単位のサイズは、所定の大きさを下回らないように表示されることになる。 For this reason, depending on the value of RS, the size of the identification image to be displayed may be smaller than the size of the identification image in the case of displaying the video in full screen. The size is displayed so as not to fall below a predetermined size.
　（表示処理の手順）
　以下では、映像内の識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を調整して表示画面に表示するまでの処理について、再び図２～図４を参照して図５に沿って説明する。図５は、表示装置１における処理手順を示すフロー図である。 (Display processing procedure)
In the following, the identification image is adjusted so that the size of the identification image when the identification image in the video is displayed on the display screen or the size of the constituent unit constituting the identification image does not fall below a predetermined size. The process until the image is displayed on the display screen will be described with reference to FIGS. 2 to 4 again and along FIG. FIG. 5 is a flowchart showing a processing procedure in the display device 1.
　はじめに、検出部１５は、表示処理部１４が表示部１８に表示させるための映像内に含まれている識別用画像を検出する。より具体的には、検出部１５は、表示処理部１４が表示部１８に表示させるための映像内に識別用画像が含まれているか否かを検出する（ステップＳ１１；以下、ステップは「Ｓ」と略記する）。検出部１５が何も検出しない、すなわち映像内に識別用画像が含まれていない場合には（Ｓ１２：ＮＯ）、Ｓ１１に戻り、Ｓ１１の処理を繰り返し行う。 First, the detection unit 15 detects an identification image included in a video that the display processing unit 14 displays on the display unit 18. More specifically, the detection unit 15 detects whether or not an image for identification is included in the video that the display processing unit 14 displays on the display unit 18 (step S11; hereinafter, the step is “S For short). When the detection unit 15 detects nothing, that is, when the image for identification is not included in the video (S12: NO), the process returns to S11 and the process of S11 is repeated.
　一方、図２に示すように、検出部１５が映像内に識別用画像５０ａが含まれていることを検出すると（Ｓ１２：ＹＥＳ）、次に判定部１６が、検出部１５が検出した識別用画像を、図３に示すように表示画面４０に表示する場合の識別用画像５０ｂのサイズ又は識別用画像５０ｂを構成する構成単位のサイズを算出する（Ｓ１３）。そして、判定部１６は、算出したサイズが所定の大きさを下回るか否かを判定する（Ｓ１４）。 On the other hand, as shown in FIG. 2, when the detection unit 15 detects that the image for identification 50a is included in the video (S12: YES), the determination unit 16 then detects the identification for detection detected by the detection unit 15. When the image is displayed on the display screen 40 as shown in FIG. 3, the size of the identification image 50b or the size of the structural unit constituting the identification image 50b is calculated (S13). Then, the determination unit 16 determines whether or not the calculated size is smaller than a predetermined size (S14).
　判定部１６が、算出したサイズが所定の大きさを下回らないと判定すると（Ｓ１４：ＮＯ）、判定部１６は、表示処理部１４に何の指示も与えない。したがって、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる。 If the determination unit 16 determines that the calculated size does not fall below the predetermined size (S14: NO), the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, the display processing unit 14 causes the display unit 18 to display the video supplied to the display processing unit 14 as it is.
　一方、判定部１６が、算出したサイズが所定の大きさを下回ると判定すると（Ｓ１４：ＹＥＳ）、判定部１６は、識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示するよう表示処理部１４に指示する（Ｓ１５）。 On the other hand, when the determination unit 16 determines that the calculated size is smaller than the predetermined size (S14: YES), the determination unit 16 determines the size of the identification image or the identification image when the identification image is displayed on the display screen. The display processing unit 14 is instructed to display the identification image so that the size of the constituent units constituting the image does not fall below a predetermined size (S15).
　表示処理部１４は、判定部１６からの指示を受け、識別用画像５０ａを表示画面４０に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回らないようにするために必要な、映像内の識別用画像に対する倍率（調整値）を特定する。そして、表示処理部１４は、映像を表示部１８に表示させる際に、映像内の識別用画像５０ａを当該調整値だけ拡大したものを表示部１８に表示させる。これにより、表示部１８の表示画面４０には、図４に示すように、映像内の識別用画像５０ａを表示画面４０に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回らないように調整された識別用画像５０ｃが表示される。 The display processing unit 14 receives an instruction from the determination unit 16, and when the identification image 50 a is displayed on the display screen 40, the size of the identification image or the size of the constituent unit constituting the identification image is a predetermined size. The magnification (adjustment value) for the image for identification in the video, which is necessary so as not to fall below, is specified. Then, when displaying the video on the display unit 18, the display processing unit 14 causes the display unit 18 to display the identification image 50 a in the video enlarged by the adjustment value. As a result, on the display screen 40 of the display unit 18, as shown in FIG. 4, the size of the identification image when the identification image 50 a in the video is displayed on the display screen 40, or the structural unit constituting the identification image The identification image 50c adjusted so that the size of the image does not fall below a predetermined size is displayed.
　これにより、表示画面４０上に表示する場合に小さく表示されてしまい、識別することができないような識別用画像は、識別可能な大きさに調整されて表示される。このため、本実施形態に係る表示装置１では、識別用画像が小さく表示されて識別できない事態を防ぐことができる。このように、本実施形態に係る表示装置１では、映像に含まれる識別用画像をそのまま表示すると、小さく表示されてしまうような場合であっても、何ら問題なく当該識別用画像の識別を行うことができる。 Thus, when the image is displayed on the display screen 40, the identification image that is displayed in a small size and cannot be identified is adjusted to a distinguishable size and displayed. For this reason, in the display device 1 according to the present embodiment, it is possible to prevent a situation in which the identification image is displayed in a small size and cannot be identified. As described above, in the display device 1 according to the present embodiment, if the identification image included in the video is displayed as it is, the identification image is identified without any problem even if it is displayed in a small size. be able to.
　（判定例）
　以下には、判定部１６による具体的な判定例を示す。 (Judgment example)
Below, the specific example of determination by the determination part 16 is shown.
　＜判定例１＞
　まず、識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂのサイズを用いて判定を行う場合を示す。 <Judgment example 1>
First, a case where determination is performed using the size of the identification image 50b when the identification image 50a is displayed on the display screen 40 will be described.
　映像のサイズがＷ＝１０８０、Ｈ＝１９２０であり、識別用画像５０ａのサイズがＷｑｒ＝８７．５、Ｈｑｒ＝８７．５であり、表示画面４０の解像度がＷｐ＝１０８０、Ｈｐ＝１９２０、Ｗｉ＝４８．５、Ｈｉ＝８７．８であり、映像を一画面表示（すなわち、ＲＳ＝１）する場合を想定する。 The size of the video is W = 1080, H = 1920, the size of the identification image 50a is Wqr = 87.5, Hqr = 87.5, and the resolution of the display screen 40 is Wp = 1080, Hp = 1920, Wi Assume that 48.5 and Hi = 87.8, and the video is displayed on one screen (that is, RS = 1).
　この場合の表示するための映像において、識別用画像５０ａが占める割合は、
　ＷＲｑｒ＝８７．５÷１０８０≒０．０８１
　ＨＲｑｒ＝８７．５÷１９２０≒０．０４５
　続いて、識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂのサイズは、
　Ｓｗｐ＝１×１０８０×０．０８１≒８７．５
　Ｓｈｐ＝１×１９２０×０．０４５≒８７．５
　Ｓｗｉ＝１×４８．５×０．０８１≒４．０
　Ｓｈｉ＝１×８７．８×０．０４５≒４．０
となる。 In the video for display in this case, the proportion of the identification image 50a is as follows:
WRqr = 87.5 ÷ 1080≈0.081
HRqr = 87.5 ÷ 1920≈0.045
Subsequently, the size of the identification image 50b when the identification image 50a is displayed on the display screen 40 is as follows.
Swp = 1 × 1080 × 0.081≈87.5
Shp = 1 × 1920 × 0.045≈87.5
Swi = 1 × 48.5 × 0.081≈4.0
Shi = 1 × 87.8 × 0.045≈4.0
It becomes.
　ここで、表示画面４０上に表示された識別用画像５０ｂを識別するために必要な識別用画像のサイズの最小値がＭＩＮｗｐ＝８７．５、ＭＩＮｈｐ＝８７．５、ＭＩＮｗｉ＝４．０、ＭＩＮｈｉ＝４．０とすると、
　ＭＩＮｗｐ≦Ｓｗｐ
　ＭＩＮｈｐ≦Ｓｈｐ
　ＭＩＮｗｉ≦Ｓｗｉ
　ＭＩＮｈｉ≦Ｓｈｉ
となるので、判定部１６は、算出したサイズが所定の大きさを下回らないと判定する。この場合、判定部１６は、表示処理部１４に何の指示も与えない。したがって、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる。 Here, the minimum size of the identification image necessary for identifying the identification image 50b displayed on the display screen 40 is MINwp = 87.5, MINhp = 87.5, MINwi = 4.0, MINhi. = 4.0
MINwp ≦ Swp
MINhp ≦ Shp
MINwi ≦ Swi
MINhi ≦ Shi
Therefore, the determination unit 16 determines that the calculated size does not fall below a predetermined size. In this case, the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, the display processing unit 14 causes the display unit 18 to display the video supplied to the display processing unit 14 as it is.
　＜判定例２＞
　次に、識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂを構成する構成単位のサイズを用いて判定を行う場合を示す。 <Judgment example 2>
Next, a case will be described in which determination is performed using the sizes of the constituent units constituting the identification image 50 b when the identification image 50 a is displayed on the display screen 40.
　識別用画像５０ａの構成単位（セル）の数がＷｕｑｒ＝２１、Ｈｕｑｒ＝２１である場合の識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂを構成する構成単位のサイズは、
　Ｕｗｐ＝１×１０８０×０．０８１÷２１≒４．１７
　Ｕｈｐ＝１×１９２０×０．０４５÷２１≒４．１７
　Ｕｗｉ＝１×４８．５×０．０８１÷２１≒０．１９
　Ｕｈｉ＝１×８７．８×０．０４５÷２１≒０．１９
となる。 The size of the structural unit constituting the identification image 50b when the identification image 50a is displayed on the display screen 40 when the number of structural units (cells) of the identification image 50a is Wuqr = 21 and Huqr = 21.
Uwp = 1 × 1080 × 0.081 ÷ 21≈4.17
Uhp = 1 × 1920 × 0.045 ÷ 21≈4.17
Uwi = 1 × 48.5 × 0.081 ÷ 21≈0.19
Uhi = 1 × 87.8 × 0.045 ÷ 21≈0.19
It becomes.
　ここで、表示画面４０上に表示された識別用画像５０ｂを識別するために必要な識別用画像を構成する構成単位のサイズの最小値がＭＩＮｕｗｐ＝４、ＭＩＮｕｈｐ＝４、ＭＩＮｕｗｉ＝０．０２５、ＭＩＮｕｈｉ＝０．０２５とすると、
　ＭＩＮｕｗｐ≦Ｕｗｐ
　ＭＩＮｕｈｐ≦Ｕｈｐ
　ＭＩＮｕｗｉ≦Ｕｗｉ
　ＭＩＮｕｈｉ≦Ｕｈｉ
となるので、判定部１６は、算出したサイズが所定の大きさを下回らないと判定する。この場合、判定部１６は、表示処理部１４に何の指示も与えない。したがって、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる。 Here, the minimum value of the size of the constituent unit constituting the identification image necessary for identifying the identification image 50b displayed on the display screen 40 is MINuwp = 4, MINuhp = 4, MINuwi = 0.025, If MINuhi = 0.025,
MINuup ≦ Uwp
MINuhp ≦ Uhp
MINuwi ≦ Uwi
MINuhi ≦ Uhi
Therefore, the determination unit 16 determines that the calculated size does not fall below a predetermined size. In this case, the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, the display processing unit 14 causes the display unit 18 to display the video supplied to the display processing unit 14 as it is.
　＜判定例３＞
　一方、識別用画像５０ａの構成単位（セル）の数がＷｕｑｒ＝１７７、Ｈｕｑｒ＝１７７である場合の識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂを構成する構成単位のサイズは、
　Ｕｗｐ＝１×１０８０×０．０８１÷１７７≒０．４９
　Ｕｈｐ＝１×１９２０×０．０４５÷１７７≒０．４９
　Ｕｗｉ＝１×４８．５×０．０８１÷１７７≒０．０２３
　Ｕｈｉ＝１×８７．８×０．０４５÷１７７≒０．０２３
となる。 <Judgment example 3>
On the other hand, the size of the structural unit constituting the identification image 50b when the identification image 50a is displayed on the display screen 40 when the number of structural units (cells) of the identification image 50a is Wuqr = 177 and Huqr = 177. Is
Uwp = 1 × 1080 × 0.081 ÷ 177≈0.49
Uhp = 1 × 1920 × 0.045 ÷ 177≈0.49
Uwi = 1 × 48.5 × 0.081 ÷ 177≈0.023
Uhi = 1 × 87.8 × 0.045 ÷ 177≈0.023
It becomes.
　ここで、表示画面４０上に表示された識別用画像５０ｂを識別するために必要な識別用画像を構成する構成単位のサイズの最小値がＭＩＮｕｗｐ＝４、ＭＩＮｕｈｐ＝４、ＭＩＮｕｗｉ＝０．０２５、ＭＩＮｕｈｉ＝０．０２５とすると、
　ＭＩＮｕｗｐ＞Ｕｗｐ
　ＭＩＮｕｈｐ＞Ｕｈｐ
　ＭＩＮｕｗｉ＞Ｕｗｉ
　ＭＩＮｕｈｉ＞Ｕｈｉ
となるので、判定部１６は、算出したサイズが所定の大きさを下回ると判定する。この場合、判定部１６は、識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂを構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示するよう表示処理部１４に指示する。 Here, the minimum value of the size of the structural unit constituting the identification image necessary for identifying the identification image 50b displayed on the display screen 40 is MINuwp = 4, MINuhp = 4, MINuwi = 0.025, If MINuhi = 0.025,
MINupp> Uwp
MINuhp> Uhp
MINuwi> Uwi
MINuhi> Uhi
Therefore, the determination unit 16 determines that the calculated size is less than a predetermined size. In this case, the determination unit 16 displays the identification image so that the size of the constituent unit constituting the identification image 50b when the identification image 50a is displayed on the display screen 40 does not fall below a predetermined size. The display processing unit 14 is instructed.
　表示処理部１４は、識別用画像５０ａを表示画面４０に表示する場合の識別用画像５０ｂを構成する構成単位のサイズが所定の大きさを下回らないようにするために必要な、映像内の識別用画像５０ａに対する倍率（調整値）を算出する。 The display processing unit 14 performs identification within the video image so that the size of the constituent unit constituting the identification image 50b when the identification image 50a is displayed on the display screen 40 does not fall below a predetermined size. A magnification (adjustment value) for the image for use 50a is calculated.
　この場合、
　ＭＩＮｕｗｐ＝Ｃｕｗｐ×Ｕｗｐ
　ＭＩＮｕｈｐ＝Ｃｕｈｐ×Ｕｈｐ
　ＭＩＮｕｗｉ＝Ｃｕｗｉ×Ｕｗｉ
　ＭＩＮｕｈｉ＝Ｃｕｈｉ×Ｕｈｉ
を満たす調整値は、
　Ｃｕｗｐ＝８．１６
　Ｃｕｈｐ＝８．１６
　Ｃｕｗｉ＝１．０９
　Ｃｕｈｉ＝１．０９
となる。そこで、表示処理部１４は、映像を表示部１８に表示させる際に、Ｃｕｗｐ，Ｃｕｈｐ，Ｃｕｗｉ，Ｃｕｈｉのうち最も大きい値の調整値（８．１６）だけ映像内の識別用画像５０ａを拡大したものを表示部１８に表示させる。これにより、表示部１８の表示画面４０には、映像内の識別用画像５０ａを表示画面４０に表示する場合の識別用画像のサイズがＭＩＮｕｗｐ、ＭＩＮｕｈｐ、ＭＩＮｕｗｉ及びＭＩＮｕｈｉを下回らないように調整された識別用画像５０ｃが表示される。 in this case,
MINupp = Cuwp × Uwp
MINuhp = Cuhp × Uhp
MINuwi = Cuwi × Uwi
MINuhi = Cuhi × Uhi
The adjustment value that satisfies
Cuwp = 8.16
Cuhp = 8.16
Cuwi = 1.09
Cuhi = 1.09
It becomes. Therefore, when displaying the video on the display unit 18, the display processing unit 14 enlarges the identification image 50a in the video by an adjustment value (8.16) having the largest value among Cuwp, Cuhp, Cuwi, and Cuhi. Things are displayed on the display unit 18. Accordingly, the size of the identification image when the identification image 50a in the video is displayed on the display screen 40 is adjusted on the display screen 40 of the display unit 18 so as not to be smaller than MINuup, MINuhp, MINuwi, and MINuhi. An identification image 50c is displayed.
　（識別用画像の表示方法）
　表示処理部１４が、映像内の識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回らないように調整した識別用画像の表示方法に特に限定はない。 (Display method of identification image)
When the display processing unit 14 displays the identification image in the video on the display screen, the size of the identification image or the size of the constituent unit constituting the identification image is adjusted so as not to fall below a predetermined size. There is no particular limitation on the image display method.
　例えば、図４に示したように、表示処理部１４は、表示画面４０に表示するための映像内における識別用画像５０ａの位置に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。すなわち、表示画面４０に表示するための映像内における識別用画像５０ａに重畳して、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。 For example, as illustrated in FIG. 4, the display processing unit 14 has the identification image 50 c adjusted so as not to fall below a predetermined size at the position of the identification image 50 a in the video to be displayed on the display screen 40. May be displayed. That is, the identification image 50c adjusted so as not to be smaller than a predetermined size may be displayed by being superimposed on the identification image 50a in the video to be displayed on the display screen 40.
　あるいは、表示処理部１４は、表示画面内における映像を表示する領域の外部に、所定の大きさを下回らないように調整した識別用画像を表示してもよい。この表示方法の例を図６に示す。本図では、識別用画像としてＱＲコード（登録商標）が示されている。 Alternatively, the display processing unit 14 may display an identification image adjusted so as not to be smaller than a predetermined size outside the area where the video is displayed in the display screen. An example of this display method is shown in FIG. In this figure, a QR code (registered trademark) is shown as an identification image.
　図６に示すように、表示画面４０内における映像を表示する領域の外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示することも可能である。すなわち、表示画面４０内における映像を表示する領域に重畳しないように、所定の大きさを下回らないように調整した識別用画像５０ｃを表示することも可能である。本図に示すように、所定の大きさを下回らないように調整した識別用画像５０ｃを、映像を表示する領域の外部に表示するために、映像自体を縮小して表示してもよい。 As shown in FIG. 6, it is also possible to display the identification image 50c adjusted so as not to be smaller than a predetermined size outside the area for displaying the video in the display screen 40. That is, it is also possible to display the identification image 50c adjusted so as not to be smaller than a predetermined size so as not to be superimposed on the image display area in the display screen 40. As shown in the drawing, the image itself may be reduced and displayed in order to display the identification image 50c adjusted so as not to be smaller than a predetermined size outside the region where the image is displayed.
　なお、映像内における識別用画像５０ａの位置に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示する場合には、表示している映像は本来の映像とは異なる旨のコメントを表示画面４０上に表示してもよい。また、表示画面４０内における映像を表示する領域の外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示する場合には、識別用画像５０ｃを所定の大きさを下回らないように調整した旨のコメントを表示画面４０上に表示してもよい。 When the identification image 50c adjusted so as not to fall below a predetermined size is displayed at the position of the identification image 50a in the video, a comment that the displayed video is different from the original video May be displayed on the display screen 40. In addition, when the identification image 50c adjusted so as not to be smaller than the predetermined size is displayed outside the image display area in the display screen 40, the identification image 50c is not smaller than the predetermined size. A comment indicating that the adjustment has been made may be displayed on the display screen 40.
　また、所定の大きさを下回らないように調整した識別用画像５０ｃの表示を取り止めるか否か、すなわち本来の映像の表示に戻すか否かをユーザが適宜選択可能に構成されていてもよい。 Further, it may be configured such that the user can appropriately select whether to stop displaying the identification image 50c adjusted so as not to fall below a predetermined size, that is, whether to return to the original video display.
　（検出部による検出タイミング）
　表示装置１では、二画面表示を用いて２つの映像を表示したり、ＰｉｎＰ（Ｐｉｃｔｕｒｅ　ｉｎ　Ｐｉｎｃｔｕｒｅ）表示等のように子画面を用いて親画面上に他の映像を表示したりすることができる。 (Detection timing by the detector)
The display device 1 can display two images using a two-screen display, or can display other images on the parent screen using a child screen such as a PinP (Picture in Picture) display. .
　図７は、二画面表示しているときの表示画面の一表示例を示しており、表示画面４０には、第１画面４５ａと第２画面４５ｂとが二画面表示されている。また、図８は、子画面表示しているときの表示画面の一表示例を示しており、表示画面４０には、親画面５５ａが表示されており、その上に子画面５５ｂが表示されている。これらの図では、識別用画像としてＱＲコード（登録商標）が示されている。 FIG. 7 shows a display example of the display screen when the two-screen display is performed, and the first screen 45a and the second screen 45b are displayed on the display screen 40 in two screens. FIG. 8 shows a display example of the display screen when the child screen is displayed. The parent screen 55a is displayed on the display screen 40, and the child screen 55b is displayed thereon. Yes. In these drawings, a QR code (registered trademark) is shown as an identification image.
　このような二画面表示及び子画面表示等の場合、図７及び図８に示すように、表示している映像のいずれかに識別用画像５０ｂが含まれていると、二画面表示又は子画面表示に応じて識別用画像も縮小して表示されることになる。そこで、検出部１５は、二画面表示及び子画面表示等、映像を表示画面に表示する場合の映像のサイズが所定のサイズよりも小さい場合に、当該映像内に識別用画像が含まれているか否かを検出するように構成されていてもよい。なお、所定のサイズは、例えば映像を表示部１８に全画面表示する場合のサイズとすることができる。 In the case of such two-screen display and sub-screen display, as shown in FIGS. 7 and 8, if any of the displayed images includes the identification image 50b, the two-screen display or sub-screen is displayed. In accordance with the display, the identification image is also reduced and displayed. Therefore, if the size of the video when the video is displayed on the display screen, such as a two-screen display or a sub-screen display, is smaller than a predetermined size, is the identification image included in the video? It may be configured to detect whether or not. Note that the predetermined size can be set to, for example, a size when the video is displayed on the display unit 18 on the full screen.
　これにより、二画面表示及び子画面表示等を行っているときには検出部１５による識別用画像の検出が行われるので、表示処理部１４により、検出部１５が検出した識別用画像を表示画面に表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像が表示画面に表示される。このため、二画面表示及び子画面表示等を行っているときに識別用画像が縮小して表示されていても、問題なく識別用画像の識別ができる。 As a result, when the two-screen display, the sub-screen display, and the like are being performed, the detection unit 15 detects the identification image, so the display processing unit 14 displays the identification image detected by the detection unit 15 on the display screen. In this case, the identification image is displayed on the display screen so that the size of the identification image or the size of the constituent unit constituting the identification image does not fall below a predetermined size. For this reason, even when the identification image is displayed in a reduced size during the two-screen display or the sub-screen display, the identification image can be identified without any problem.
　＜二画面表示＞
　以下では、映像を表示画面に表示する場合の映像のサイズが所定のサイズよりも小さい場合として、二画面表示を行っている場合を例に挙げて説明する。例えば、所定のサイズを表示部１８に全画面表示する場合の映像のサイズと仮定すると、二画面表示の場合、表示画面４０に表示している第１画面４５ａ及び第２画面４５ｂは何れも表示部１８に全画面表示する場合のサイズよりも小さい。そこで、検出部１５は、第１画面４５ａ及び第２画面４５ｂに表示するためのそれぞれの映像の少なくとも何れか含まれている識別用画像の検出を行う。より具体的には、検出部１５は、第１画面４５ａ及び第２画面４５ｂに表示するためのそれぞれの映像の少なくとも何れかに識別用画像が含まれているか否かの検出を行う。 <Two-screen display>
In the following, a case where a two-screen display is performed will be described as an example where the size of the video when the video is displayed on the display screen is smaller than a predetermined size. For example, assuming that the predetermined size is the size of the video when the display unit 18 displays the entire screen, in the case of the two-screen display, both the first screen 45a and the second screen 45b displayed on the display screen 40 are displayed. It is smaller than the size when full screen display is performed on the part 18. Therefore, the detection unit 15 detects an identification image included in at least one of the respective images to be displayed on the first screen 45a and the second screen 45b. More specifically, the detection unit 15 detects whether or not an identification image is included in at least one of the videos to be displayed on the first screen 45a and the second screen 45b.
　検出部１５が、第１画面４５ａ及び第２画面４５ｂに表示するためのそれぞれの映像の少なくとも何れかに識別用画像が含まれていることを検出すると、判定部１６は、検出部１５が検出した識別用画像を第１画面４５ａ又は第２画面４５ｂに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回るか否かを判定する。 When the detection unit 15 detects that at least one of the images to be displayed on the first screen 45a and the second screen 45b includes an identification image, the determination unit 16 detects that the detection unit 15 It is determined whether the size of the identification image or the size of the constituent unit constituting the identification image when the identification image is displayed on the first screen 45a or the second screen 45b is less than a predetermined size.
　例えば、第１画面４５ａに表示するための映像に含まれている識別用画像に関しては、判定部１６は、第１画面４５ａに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズに基づき判定を行い、第２画面４５ｂに表示するための映像に含まれている識別用画像に関しては、判定部１６は、第２画面４５ｂに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズに基づき判定を行う。また、第１画面４５ａ及び第２画面４５ｂに表示するためのそれぞれの映像の何れにも識別用画像が含まれている場合は、判定部１６は、各識別用画像に関して判定を行う。 For example, with respect to the identification image included in the video to be displayed on the first screen 45a, the determination unit 16 configures the size of the identification image or the identification image when displayed on the first screen 45a. With respect to the identification image included in the video to be displayed on the second screen 45b, based on the unit size, the determination unit 16 determines the size of the identification image when displayed on the second screen 45b or The determination is performed based on the size of the constituent unit constituting the identification image. In addition, in a case where an identification image is included in any of the videos to be displayed on the first screen 45a and the second screen 45b, the determination unit 16 performs determination on each identification image.
　そして、第１画面４５ａ又は第２画面４５ｂに識別用画像を表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回ると判定部１６が判定すると、表示処理部１４は、当該識別用画像を第１画面４５ａ又は第２画面４５ｂに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示部１８に表示させる。 And when the determination part 16 determines that the size of the image for identification in the case of displaying the image for identification on the 1st screen 45a or the 2nd screen 45b or the size of the structural unit which comprises the image for identification is less than predetermined magnitude | size. The display processing unit 14 determines that the size of the identification image or the size of the constituent unit constituting the identification image when the identification image is displayed on the first screen 45a or the second screen 45b is less than a predetermined size. The image for identification is displayed on the display unit 18 so as not to be present.
　二画面表示しているときにおいて、所定の大きさを下回らないように調整した識別用画像の表示例を図９及び図１０に示す。これらの図では、識別用画像としてＱＲコード（登録商標）が示されている。 FIG. 9 and FIG. 10 show display examples of the image for identification adjusted so as not to fall below a predetermined size during the two-screen display. In these drawings, a QR code (registered trademark) is shown as an identification image.
　図９に示すように、表示処理部１４は、表示画面４０に表示するための第１画面４５ａ内における識別用画像の位置に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。あるいは、図１０に示すように、表示処理部１４は、表示画面４０内における第１画面４５ａ及び第２画面４５ｂの外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。図１０に示すように、所定の大きさを下回らないように調整した識別用画像５０ｃを第１画面４５ａ及び第２画面４５ｂの外部に表示するために、第１画面４５ａ及び第２画面４５ｂ自体を移動させたり、縮小させたりしてもよい。 As shown in FIG. 9, the display processing unit 14 applies the identification image 50 c adjusted so as not to fall below a predetermined size at the position of the identification image in the first screen 45 a to be displayed on the display screen 40. It may be displayed. Alternatively, as shown in FIG. 10, the display processing unit 14 displays an identification image 50 c adjusted so as not to fall below a predetermined size outside the first screen 45 a and the second screen 45 b in the display screen 40. May be. As shown in FIG. 10, in order to display the identification image 50c adjusted so as not to be smaller than a predetermined size outside the first screen 45a and the second screen 45b, the first screen 45a and the second screen 45b themselves. May be moved or reduced.
　なお、表示画面４０内における第１画面４５ａ及び第２画面４５ｂの外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示する場合、当該識別用画像５０ｃを表示する位置に特に限定はないが、第１画面４５ａ及び第２画面４５ｂのうち対応する画面近傍に表示することが好ましい。対応する画面とは、識別用画像５０ｃの表示元となっている画面である。これにより、表示されている識別用画像５０ｃが何れの画面に表示されている識別用画像を調整したものであるのかユーザは簡単に見分けることができる。 When the identification image 50c adjusted so as not to be smaller than a predetermined size is displayed outside the first screen 45a and the second screen 45b in the display screen 40, the identification image 50c is displayed at a position where it is displayed. Although there is no particular limitation, it is preferable to display near the corresponding screen of the first screen 45a and the second screen 45b. The corresponding screen is a screen from which the identification image 50c is displayed. As a result, the user can easily recognize which screen the identification image 50c being displayed is obtained by adjusting the identification image displayed on which screen.
　したがって例えば、表示処理部１４は、表示画面４０に識別用画像を含む映像を全画面表示する場合の識別用画像の第１のサイズよりも小さい第２のサイズで識別用画像を表示する場合には、当該第２のサイズよりも拡大した識別用画像を表示画面４０に別途表示する構成としてもよい。 Therefore, for example, the display processing unit 14 displays the identification image in a second size that is smaller than the first size of the identification image when the image including the identification image is displayed on the full screen on the display screen 40. May be configured to separately display an identification image larger than the second size on the display screen 40.
　あるいは、表示処理部１４は、表示画面４０に識別用画像を含む映像を全画面表示する場合の識別用画像の第１のサイズよりも小さい第２のサイズで識別用画像を表示する場合には、当該第１のサイズで識別用画像を表示してもよい。 Alternatively, when the display processing unit 14 displays the identification image in a second size smaller than the first size of the identification image when the video including the identification image is displayed on the full screen on the display screen 40. The identification image may be displayed in the first size.
　〔第２の実施形態〕
　＜子画面表示＞
　上述したように、映像を表示画面に表示する場合の映像のサイズが所定のサイズよりも小さい場合として、子画面表示を行っている場合も想定される。以下では、子画面表示を行っている場合について説明する。 [Second Embodiment]
<Sub-screen display>
As described above, a case where a small screen is displayed is assumed as a case where the size of the video when the video is displayed on the display screen is smaller than a predetermined size. Hereinafter, a case where a small screen is displayed will be described.
　例えば、所定のサイズを表示部１８に全画面表示する場合の映像のサイズと仮定すると、子画面表示の場合、表示画面４０に表示している親画面５５ａ及び子画面５５ｂのうち、子画面５５ｂは表示部１８に全画面表示する場合のサイズよりも小さい。そこで、検出部１５は、子画面５５ｂに表示するための映像に含まれている識別用画像の検出を行う。より具体的には、検出部１５は、子画面５５ｂに表示するための映像に識別用画像が含まれているか否かの検出を行う。 For example, assuming that a predetermined size is the size of the video when the display unit 18 is displayed on the entire screen, in the case of the small screen display, of the parent screen 55a and the small screen 55b displayed on the display screen 40, the small screen 55b. Is smaller than the size in the case of full screen display on the display unit 18. Therefore, the detection unit 15 detects the identification image included in the video to be displayed on the child screen 55b. More specifically, the detection unit 15 detects whether or not an image for identification is included in the video to be displayed on the child screen 55b.
　検出部１５が、子画面５５ｂに表示するための映像に識別用画像が含まれていることを検出すると、判定部１６は、検出部１５が検出した識別用画像を子画面５５ｂに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回るか否かを判定する。 When the detection unit 15 detects that the image for identification is included in the video to be displayed on the sub screen 55b, the determination unit 16 displays the identification image detected by the detection unit 15 on the sub screen 55b. It is determined whether the size of the identification image or the size of the constituent unit constituting the identification image is less than a predetermined size.
　そして、子画面５５ｂに識別用画像を表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが所定の大きさを下回ると判定部１６が判定すると、表示処理部１４は、当該識別用画像を子画面５５ｂに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズが、所定の大きさを下回らないように識別用画像を表示部１８に表示させる。 When the determination unit 16 determines that the size of the identification image in the case where the identification image is displayed on the sub-screen 55b or the size of the constituent unit constituting the identification image is less than a predetermined size, the display processing unit 14 When the identification image is displayed on the small screen 55b, the identification image is displayed on the display unit 18 so that the size of the identification image or the size of the constituent unit constituting the identification image does not fall below a predetermined size. Let
　子画面表示しているときにおいて、所定の大きさを下回らないように調整した識別用画像の表示例を図１１に示す。本図では、識別用画像としてＱＲコード（登録商標）が示されている。 FIG. 11 shows a display example of the identification image adjusted so as not to fall below a predetermined size when the small screen is displayed. In this figure, a QR code (registered trademark) is shown as an identification image.
　図１１に示すように、表示処理部１４は、表示画面４０内における親画面５５ａ及び子画面５５ｂの外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。図１１に示すように、所定の大きさを下回らないように調整した識別用画像５０ｃを親画面５５ａ及び子画面５５ｂの外部に表示するために、親画面５５ａ及び子画面５５ｂ自体を縮小させてもよい。 As shown in FIG. 11, the display processing unit 14 may display an identification image 50 c adjusted so as not to be smaller than a predetermined size outside the parent screen 55 a and the child screen 55 b in the display screen 40. . As shown in FIG. 11, in order to display the identification image 50c adjusted so as not to fall below a predetermined size outside the parent screen 55a and the child screen 55b, the parent screen 55a and the child screen 55b itself are reduced. Also good.
　なお、以上では、表示画面４０内における親画面５５ａ及び子画面５５ｂの外部に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示する例を示したが、本実施形態はこれに限定されるわけではない。例えば、子画面５５ｂ内に所定の大きさを下回らないように調整した識別用画像５０ｃを表示するだけの領域があるのであれば、表示処理部１４は、子画面５５ｂ内における識別用画像の位置に、所定の大きさを下回らないように調整した識別用画像５０ｃを表示してもよい。 In the above description, the example in which the identification image 50c adjusted so as not to be smaller than the predetermined size is displayed outside the parent screen 55a and the child screen 55b in the display screen 40. It is not limited to. For example, if there is an area in the child screen 55b that only displays the identification image 50c adjusted so as not to fall below a predetermined size, the display processing unit 14 determines the position of the identification image in the child screen 55b. Alternatively, the identification image 50c adjusted so as not to fall below a predetermined size may be displayed.
　また、以上では、検出部１５は、映像のサイズが所定のサイズよりも小さい子画面５５ｂに表示するための映像内に識別用画像が含まれるか否かの検出を行っているが、本実施形態はこれに限定されるわけではない。例えば、検出部１５による検出は、親画面５５ａ及び子画面５５ｂそれぞれに表示する映像に関して行ってもよい。 Further, in the above, the detection unit 15 detects whether or not an identification image is included in the video to be displayed on the sub-screen 55b whose video size is smaller than the predetermined size. The form is not limited to this. For example, the detection by the detection unit 15 may be performed on images displayed on the parent screen 55a and the child screen 55b.
　この場合は、二画面表示の場合と同じであり、親画面５５ａに表示するための映像に含まれている識別用画像に関しては、判定部１６は、親画面５５ａに表示する場合の識別用画像のサイズ又は識別用画像を構成する構成単位のサイズに基づき判定を行う。また、親画面５５ａ及び子画面５５ｂに表示するためのそれぞれの映像の何れにも識別用画像が含まれている場合は、判定部１６は、各識別用画像に関して判定を行う。 In this case, it is the same as in the case of the two-screen display, and for the identification image included in the video to be displayed on the parent screen 55a, the determination unit 16 uses the identification image to be displayed on the parent screen 55a. The determination is made based on the size of the image or the size of the structural unit constituting the identification image. In addition, when each of the images to be displayed on the parent screen 55a and the child screen 55b includes an identification image, the determination unit 16 performs determination on each identification image.
　〔第３の実施形態〕
　本発明に係る表示装置は、実施形態１に示したものに限定されるものではなく、例えば以下に説明するような構成としてもよい。なお、以下に示す表示装置の構成は、基本的には実施形態１の構成と共通することから、以下では、第１の実施形態に係る表示装置と異なる点を中心として説明する。 [Third Embodiment]
The display device according to the present invention is not limited to that shown in the first embodiment, and may be configured as described below, for example. Since the configuration of the display device shown below is basically the same as the configuration of the first embodiment, the following description will focus on differences from the display device according to the first embodiment.
　本実施形態において、表示処理部１４は、後述するチューナ部１９が受信した放送波から取得したテレビ放送映像、又は後述する外部通信部２０が通信ネットワーク２３を介して取得した（例えば、ストリーミング配信された）コンテンツ映像等、表示処理部１４に供給された映像を表示部１８に表示させるための処理を行う。表示処理部１４は、後述する判定部１６からの指示に基づき、識別不可能化画像を表示部１８に表示させる処理も行う。 In the present embodiment, the display processing unit 14 is a television broadcast video acquired from a broadcast wave received by a tuner unit 19 described later, or an external communication unit 20 described later acquired via a communication network 23 (for example, streaming distribution is performed). (A) Processing for displaying the video supplied to the display processing unit 14 such as a content video on the display unit 18 is performed. The display processing unit 14 also performs processing for displaying the non-identifiable image on the display unit 18 based on an instruction from the determination unit 16 described later.
　なお、本実施形態において、識別用画像とは、バーコード等の一次元コード、ＱＲコード（登録商標）等の二次元コード、及び電子透かし等、データが埋め込まれた画像を意味する。なお、電子透かしとは、動画像及び静止画像等のコンテンツに埋め込まれた情報であり、ユーザが視認できないものである。ここで、識別用画像に埋め込まれたデータとは、例えば後述する外部通信部２０が通信ネットワーク２３を介して外部の情報にアクセスするためのデータである。 In the present embodiment, the identification image means an image in which data such as a one-dimensional code such as a barcode, a two-dimensional code such as a QR code (registered trademark), and a digital watermark is embedded. The digital watermark is information embedded in content such as a moving image and a still image and cannot be visually recognized by the user. Here, the data embedded in the identification image is data for the external communication unit 20 described later to access external information via the communication network 23, for example.
　また、識別不可能化画像とは、識別用画像を隠す目隠し画像等、識別用画像に埋め込まれたデータを抽出できないようにするための画像である。この識別不可能化画像により、識別用画像は識別不可能となる。表示処理部１４は、識別不可能化画像を識別用画像の上に重畳した映像を表示部１８に表示させてもよいし、識別用画像を識別不可能化画像に置き換えた映像を表示部１８に表示させてもよく、ユーザが識別用画像の代わりに識別不可能化画像を視認できれば識別不可能化画像の表示方法に特に限定はない。 Also, the non-identifiable image is an image that prevents extraction of data embedded in the identification image, such as a blindfold image that hides the identification image. With this non-identifiable image, the identification image cannot be identified. The display processing unit 14 may cause the display unit 18 to display a video obtained by superimposing the non-identifiable image on the identification image, or display the video obtained by replacing the identification image with the non-identifiable image. The display method of the non-identifiable image is not particularly limited as long as the user can visually recognize the non-identifiable image instead of the identification image.
　検出部１５は、表示部１８の表示画面に表示するための映像内に識別用画像が含まれているか否を検出する。具体的には、検出部１５は、表示処理部１４が表示部１８に表示させるための映像を取得して、画像認識処理により映像内に識別用画像が含まれているか否かを検出する。より具体的には、検出部１５は、表示処理部１４が表示部１８に表示させるための映像をフレームごとに解析し、フレーム画像に含まれている識別用画像を認識する。 The detecting unit 15 detects whether an image for identification is included in the video to be displayed on the display screen of the display unit 18. Specifically, the detection unit 15 acquires a video to be displayed on the display unit 18 by the display processing unit 14 and detects whether or not an identification image is included in the video by image recognition processing. More specifically, the detection unit 15 analyzes a video for the display processing unit 14 to display on the display unit 18 for each frame, and recognizes an identification image included in the frame image.
　また、検出部１５は、映像内に識別用画像が含まれていることを検出すると、当該識別用画像が有効であるか否かを判定するように判定部１６に指示する。 Further, when detecting that the image for identification is included in the video, the detection unit 15 instructs the determination unit 16 to determine whether or not the image for identification is valid.
　判定部１６は、検出部１５が検出した識別用画像が有効であるか否かを判定する。判定部１６による具体的な判定方法については、後述する。判定部１６は、当該識別用画像が有効でないと判定すると、識別用画像に埋め込まれたデータを抽出できないようにするための識別不可能化画像を表示するように表示処理部１４に指示する。 The determination unit 16 determines whether or not the identification image detected by the detection unit 15 is valid. A specific determination method by the determination unit 16 will be described later. If the determination unit 16 determines that the identification image is not valid, the determination unit 16 instructs the display processing unit 14 to display a non-identifiable image for preventing extraction of data embedded in the identification image.
　なお、検出部１５が検出した識別用画像の映像内における位置情報は、判定部１６を介して表示処理部１４に送られるため、表示処理部１４は、当該位置情報に基づき、映像内における識別用画像の位置に、当該識別用画像に埋め込まれたデータを抽出できないようにするための識別不可能化画像を表示部１８に表示させる。 Since the position information in the video of the identification image detected by the detection unit 15 is sent to the display processing unit 14 via the determination unit 16, the display processing unit 14 identifies the image in the video based on the position information. The display unit 18 displays a non-identifiable image for preventing extraction of data embedded in the identification image at the position of the image for use.
　（判定部による判定）
　また、判定部１６は、以下に示す（１）～（４）のいずれかの方法で識別用画像が有効であるか否かを判定している。
（１）表示画面に表示するための映像が録画された映像である場合には、判定部１６は、当該映像内に含まれる識別用画像が有効でないと判定する。具体的には、判定部１６は、表示処理部１４が表示部１８に表示させるための映像が録画された映像であるか否かを判定する。 (Judgment by judgment part)
The determination unit 16 determines whether or not the identification image is valid by any one of methods (1) to (4) described below.
(1) If the video to be displayed on the display screen is a recorded video, the determination unit 16 determines that the identification image included in the video is not valid. Specifically, the determination unit 16 determines whether or not the video for the display processing unit 14 to display on the display unit 18 is a recorded video.
　例えば、判定部１６は、メモリ１７又は外部機器接続部２１から供給された映像を表示処理部１４が表示部１８に表示させる場合は、当該映像は録画された映像であると判定することができる。そして、判定部１６は、表示処理部１４が表示部１８に表示させるための映像が録画された映像であると判定した場合には、当該映像内に含まれる識別用画像は無効であると判定する。
（２）識別用画像が特定のリンク先を示すリンク先情報を含んでおり、当該識別用画像に含まれる上記のリンク先情報が示すリンク先にアクセスできない場合には、判定部１６は、当該識別用画像が有効でないと判定する。具体的には、判定部１６は、識別用画像に含まれるリンク先情報が示すリンク先にアクセスができるか否かを判定する。 For example, when the display processing unit 14 displays the video supplied from the memory 17 or the external device connection unit 21 on the display unit 18, the determination unit 16 can determine that the video is a recorded video. . If the determination unit 16 determines that the video to be displayed on the display unit 18 by the display processing unit 14 is a recorded video, the determination unit 16 determines that the identification image included in the video is invalid. To do.
(2) When the identification image includes link destination information indicating a specific link destination and the link destination indicated by the link destination information included in the identification image cannot be accessed, the determination unit 16 It is determined that the identification image is not valid. Specifically, the determination unit 16 determines whether or not the link destination indicated by the link destination information included in the identification image can be accessed.
　例えば、判定部１６は、識別用画像からリンク先情報を読み出し、外部通信部２０に上記のリンク先情報が示すリンク先にアクセスさせることにより、当該リンク先にアクセスできるか否かを判定することができる。そして、判定部１６は、識別用画像に含まれるリンク先情報が示すリンク先にアクセスができないと判定した場合には、当該識別用画像は無効であると判定する。
（３）識別用画像が特定のリンク先へのアクセス期限を示すアクセス情報を含んでおり、当該識別用画像に含まれる上記のアクセス情報が示すアクセス期限を過ぎていると判定した場合に、判定部１６は、当該識別用画像が有効でないと判定する。具体的には、判定部１６は、識別用画像に含まれるアクセス情報が示すアクセス期限を過ぎているか否かを判定する。 For example, the determination unit 16 reads out link destination information from the identification image, and determines whether the link destination can be accessed by causing the external communication unit 20 to access the link destination indicated by the link destination information. Can do. If the determination unit 16 determines that the link destination indicated by the link destination information included in the identification image cannot be accessed, the determination unit 16 determines that the identification image is invalid.
(3) The determination is made when it is determined that the identification image includes access information indicating an access time limit for a specific link destination and the access time limit indicated by the access information included in the identification image has passed. The unit 16 determines that the identification image is not valid. Specifically, the determination unit 16 determines whether or not the access time limit indicated by the access information included in the identification image has passed.
　例えば、判定部１６は、識別用画像からアクセス情報を読み出し、当該アクセス情報が示すアクセス期限が過ぎているか否かを判定することができる。そして、判定部１６は、識別用画像に含まれるアクセス情報が示すアクセス期限を過ぎていると判定した場合には、当該識別用画像は無効であると判定する。
（４）識別用画像がパレンタル情報を含んでおり、当該識別用画像に含まれるパレンタル情報が、予めユーザによって表示装置１に設定されている閲覧条件を満たしていない場合に、判定部１６は、当該識別用画像が有効でないと判定する。なお、パレンタル情報とは、識別用画像に対応するリンク先のコンテンツの内容に応じた情報であり、コンテンツの対象年齢及びジャンル等の情報である。また、閲覧条件とは、ユーザに悪影響を及ぼす虞のあるコンテンツの閲覧を制限するために、表示装置１に設定されている閲覧条件（例えば、年齢制限及びジャンル制限等の閲覧制限の条件）である。例えば、対象年齢が一定年齢以上のコンテンツ又は特定のジャンルのコンテンツの閲覧を制限する閲覧条件である。この閲覧条件は、例えばメモリ１７に格納されており、ユーザごとに設定されていてもよい。 For example, the determination unit 16 can read the access information from the identification image and determine whether the access time limit indicated by the access information has passed. If the determination unit 16 determines that the access time limit indicated by the access information included in the identification image has passed, the determination unit 16 determines that the identification image is invalid.
(4) When the identification image includes parental information and the parental information included in the identification image does not satisfy the viewing conditions set in the display device 1 by the user in advance, the determination unit 16 Determines that the identification image is not valid. The parental information is information according to the content of the linked content corresponding to the identification image, and is information such as the target age and genre of the content. The browsing conditions are browsing conditions (for example, browsing restrictions such as age restrictions and genre restrictions) set in the display device 1 in order to limit browsing of contents that may adversely affect the user. is there. For example, it is a viewing condition that restricts browsing of content whose target age is over a certain age or content of a specific genre. This browsing condition is stored in, for example, the memory 17 and may be set for each user.
　例えば、判定部１６は、識別用画像からパレンタル情報を読み出し、当該パレンタル情報とメモリ１７に格納されている閲覧条件とを比較することにより、パレンタル情報が閲覧条件を満たしているか否かを判定することができる。そして、判定部１６は、識別用画像に含まれるパレンタル情報が、表示装置１に記憶されている閲覧条件を満たしていないと判定した場合には、当該識別用画像は無効であると判定する。 For example, the determination unit 16 reads the parental information from the identification image, and compares the parental information with the viewing conditions stored in the memory 17 to determine whether the parental information satisfies the viewing conditions. Can be determined. If the determination unit 16 determines that the parental information included in the identification image does not satisfy the browsing conditions stored in the display device 1, the determination unit 16 determines that the identification image is invalid. .
　なお、アクセス情報及びパレンタル情報は、放送局が予め識別用画像に埋め込んでいてもよいが、表示装置１が、識別用画像に含まれるリンク先情報が示すリンク先へのアクセス期限情報を識別用画像に埋め込む構成、及び識別用画像に対応するリンク先のコンテンツの内容に応じたパレンタル情報を識別用画像に埋め込む構成も可能である。 The access information and parental information may be embedded in the identification image in advance by the broadcast station, but the display device 1 identifies access time limit information to the link destination indicated by the link destination information included in the identification image. A configuration in which the parental information corresponding to the content of the linked content corresponding to the identification image is embedded in the identification image is also possible.
　例えば、表示装置１が映像を取得した時点（放送波からテレビ放送映像を取得した時点、通信ネットワーク２３を介して映像コンテンツを取得した時点等）で、表示装置１が当該映像内の識別用画像にアクセス情報及びパレンタル情報を埋め込んでもよい。なお、アクセス情報及びパレンタル情報は、例えばＨＴＭＬソース内にコメントとして記述することができる。 For example, at the time when the display device 1 acquires the video (the time when the television broadcast video is acquired from the broadcast wave, the time when the video content is acquired via the communication network 23, etc.), the display device 1 uses the identification image in the video. You may embed access information and parental information. The access information and parental information can be described as comments in the HTML source, for example.
　このように、映像が録画映像であったり、識別用画像に埋め込まれたデータのリンク先にアクセス不可能又はリンク先の有効期限が切れていたり、識別用画像に含まれるパレンタル情報がユーザの閲覧条件を満たしていなかったりする等、識別用画像に埋め込まれたデータを利用することができない場合に、判定部１６は、当該識別用画像が有効でないと判定することができる。例えば、識別用画像に埋め込まれたデータが通信ネットワーク２３を介して外部の情報にアクセスするためのデータである場合、当該データを用いて外部の情報にアクセスできないと、判定部１６は、当該識別用画像が有効でないと判定する。 Thus, the video is a recorded video, the link destination of the data embedded in the identification image is inaccessible or the link destination has expired, or the parental information included in the identification image is When the data embedded in the identification image cannot be used, such as when the browsing condition is not satisfied, the determination unit 16 can determine that the identification image is not valid. For example, when the data embedded in the identification image is data for accessing external information via the communication network 23, if the external information cannot be accessed using the data, the determination unit 16 determines that the identification information It is determined that the image for use is not valid.
　（表示装置の処理）
　表示装置１の表示画面の一表示例を図１２に示す。図１２の（ａ）に示すように、表示装置１では、表示画面４０に、識別用画像としてＱＲコード５０が含まれている映像を表示する場合がある。このとき、ユーザがＱＲコード５０をスマートフォン等で読み取れば、例えば図１２の（ｂ）に示すように、ＱＲコード５０に対応するＵＲＬのサイトが提供する表示画像がスマートフォン等に表示され、ＱＲコード５０に対応するＵＲＬのサイトにアクセスできるように構成されている。 (Processing of display device)
One display example of the display screen of the display device 1 is shown in FIG. As illustrated in FIG. 12A, the display device 1 may display a video including the QR code 50 as an identification image on the display screen 40. At this time, if the user reads the QR code 50 with a smartphone or the like, for example, as shown in FIG. 12B, the display image provided by the site of the URL corresponding to the QR code 50 is displayed on the smartphone or the like. 50 is configured to be able to access a URL site corresponding to 50.
　このようなＱＲコード５０は、対応するＵＲＬのサイトの有効期限が切れている等、映像を視聴するタイミングによっては、有効ではない可能性がある。そこで、表示装置１では、表示画面４０に表示するための映像内に含まれるＱＲコード５０が有効であるか否かに応じて、映像内のＱＲコード５０に埋め込まれたデータを抽出できないようにするための識別不可能化画像（図示せず）を表示画面４０に表示する。この処理について、図１３及び図１４に基づいて具体的に説明する。ここで、図１３は、本実施形態に係る表示装置の処理手順を示すフロー図であり、図１４は、本実施形態に係る表示装置の表示画面の一表示例を示す図である。なお、以下では、識別不可能化画像として、ＱＲコード５０を隠す目隠し画像を表示する例を挙げて説明する。 Such a QR code 50 may not be valid depending on the timing of viewing the video, such as the expiration date of the corresponding URL site. Therefore, the display device 1 cannot extract data embedded in the QR code 50 in the video depending on whether or not the QR code 50 included in the video to be displayed on the display screen 40 is valid. A non-identifiable image (not shown) for display is displayed on the display screen 40. This process will be specifically described with reference to FIGS. Here, FIG. 13 is a flowchart illustrating a processing procedure of the display device according to the present embodiment, and FIG. 14 is a diagram illustrating a display example of the display screen of the display device according to the present embodiment. Hereinafter, an example in which a blindfolded image that hides the QR code 50 is displayed as an indistinguishable image will be described.
　はじめに、検出部１５は、表示処理部１４が表示部１８に表示させるための映像内にＱＲコード５０が含まれているか否かを検出する（ステップＳ２１；以下、ステップは「Ｓ」と略記する）。例えば、検出部１５は、表示処理部１４が表示部１８に表示させるための映像をフレームごとに画像認識処理をしたり、放送波から取得したメタ情報を参照したりして、当該映像内にＱＲコード５０が含まれているか否かを検出する。検出部１５が何も検出しない、すなわち映像内にＱＲコード５０が含まれていない場合には（Ｓ２２：ＮＯ）、Ｓ２１に戻り、Ｓ２１の処理を繰り返し行う。 First, the detection unit 15 detects whether or not the QR code 50 is included in the video that the display processing unit 14 displays on the display unit 18 (step S21; hereinafter, step is abbreviated as “S”). ). For example, the detection unit 15 performs image recognition processing for each frame of the video to be displayed on the display unit 18 by the display processing unit 14 or refers to meta information acquired from a broadcast wave, so that the video is displayed in the video. It is detected whether or not the QR code 50 is included. When the detection unit 15 detects nothing, that is, when the QR code 50 is not included in the video (S22: NO), the process returns to S21 and the process of S21 is repeated.
　一方、検出部１５がＱＲコード５０を検出すると（Ｓ２２：ＹＥＳ）、次に判定部１６がＱＲコード５０の有効性を判定する（Ｓ２３）。例えば、判定部１６は、表示画面４０に表示するための映像が録画された映像であるか否か、リンク先情報が示すリンク先にアクセスできるか否か、ＱＲコード５０に含まれるアクセス情報又はパレンタル情報等に応じて、当該映像に含まれるＱＲコード５０が有効であるか否かを判定する。 On the other hand, when the detection unit 15 detects the QR code 50 (S22: YES), the determination unit 16 determines the validity of the QR code 50 (S23). For example, the determination unit 16 determines whether the video to be displayed on the display screen 40 is a recorded video, whether the link destination indicated by the link destination information is accessible, the access information included in the QR code 50, or It is determined whether the QR code 50 included in the video is valid according to the parental information or the like.
　判定部１６がＱＲコード５０は無効であると判定すると（Ｓ２４：ＮＯ）、判定部１６は、ＱＲコード５０に埋め込まれたデータを抽出できないようにするために当該ＱＲコード５０を隠す目隠し画像を表示するように表示処理部１４に指示する。表示処理部１４は、判定部１６からの指示に基づき、映像内のＱＲコード５０を隠す目隠し画像を表示部１８に表示させる。そして、表示部１８は、図４に示すように、映像内のＱＲコード５０を隠す目隠し画像５１を表示画面４０に表示する（Ｓ２６）。 If the determination unit 16 determines that the QR code 50 is invalid (S24: NO), the determination unit 16 displays a blindfold image that hides the QR code 50 so that the data embedded in the QR code 50 cannot be extracted. The display processing unit 14 is instructed to display. Based on an instruction from the determination unit 16, the display processing unit 14 causes the display unit 18 to display a blindfold image that hides the QR code 50 in the video. Then, as shown in FIG. 4, the display unit 18 displays a blindfold image 51 that hides the QR code 50 in the video on the display screen 40 (S26).
　一方、判定部１６がＱＲコード５０は有効であると判定した場合には（Ｓ２４：ＹＥＳ）、判定部１６は、表示処理部１４に何の指示も与えない。したがって、この場合には、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる（Ｓ２５）。 On the other hand, when the determination unit 16 determines that the QR code 50 is valid (S24: YES), the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, in this case, the display processing unit 14 causes the display unit 18 to display the video supplied to the display processing unit 14 as it is (S25).
　以上のように、本実施形態によれば、映像内のＱＲコード５０が有効でない、すなわちＱＲコード５０が無効である場合には、ＱＲコード５０は目隠し画像５１によって隠されて表示画面４０に表示される。これにより、映像内のＱＲコード５０は、目隠し画像５１によって識別不可能となる。そのため、ユーザが無効なＱＲコード５０の読み取りを行う事態を防ぐことができる。したがって、本実施形態によれば、映像に含まれる無効なＱＲコード５０によってユーザが混乱するのを防止できる。 As described above, according to the present embodiment, when the QR code 50 in the video is not valid, that is, when the QR code 50 is invalid, the QR code 50 is hidden by the blindfold image 51 and displayed on the display screen 40. Is done. As a result, the QR code 50 in the video cannot be identified by the blindfold image 51. Therefore, it is possible to prevent the user from reading the invalid QR code 50. Therefore, according to the present embodiment, the user can be prevented from being confused by the invalid QR code 50 included in the video.
　なお、図１４では、目隠し画像５１は、ＱＲコード５０全体を塗りつぶしたようなベタ塗りの画像としている。しかしながら、目隠し画像は、識別用画像を隠すことができる画像であれば、特に限定されるものではない。さらに、以上では、識別不可能化画像として目隠し画像を例に挙げているが、識別不可能化画像は目隠し画像に限定されない。識別不可能化画像は、識別用画像が識別不可能となっていることが分かるような画像であれば、いかなる画像であってもよい。 In FIG. 14, the blindfold image 51 is a solid image in which the entire QR code 50 is painted. However, the blindfold image is not particularly limited as long as it is an image that can hide the identification image. Furthermore, in the above description, a blindfold image is used as an example of a non-identifiable image, but the non-identifiable image is not limited to a blindfold image. The non-identifiable image may be any image as long as it is understood that the identification image cannot be identified.
　また、以上では、識別用画像がＱＲコードである場合を例に挙げているが、識別用画像はＱＲコードに限定されず、他の種類の識別用画像であってもよい。 In the above description, the identification image is a QR code. However, the identification image is not limited to a QR code, and may be another type of identification image.
　なお、ＱＲコード等の識別用画像内にアクセス情報及びパレンタル情報の少なくとも何れかを埋め込み、当該アクセス情報及びパレンタル情報の少なくとも何れかが埋め込まれた識別用画像を含む映像を放送波又はインターネット回線を通じて送信する送信装置も本明細書に記載された発明に含まれる。また、このような送信装置では、アクセス情報及びパレンタル情報を、例えばＨＴＭＬソース内にコメントとして記述する構成とすることができる。 Note that at least one of access information and parental information is embedded in an identification image such as a QR code, and a video including an identification image in which at least one of the access information and parental information is embedded is broadcast wave or the Internet. A transmission device that transmits through a line is also included in the invention described in this specification. Further, in such a transmission apparatus, the access information and parental information can be described as comments in an HTML source, for example.
　〔第４の実施形態〕
　上述したように、実施形態１では、無効な識別用画像に埋め込まれたデータを抽出できないようにするための識別不可能化画像を表示する構成を示したが、本発明はこれに限定されるわけではない。例えば、識別用画像が無効である旨のコーションを表示画面に表示してもよい。この構成について以下に説明する。 [Fourth Embodiment]
As described above, in the first embodiment, the configuration in which the non-identifiable image is displayed so that the data embedded in the invalid identification image cannot be extracted is shown. However, the present invention is limited to this. Do not mean. For example, a caution that the identification image is invalid may be displayed on the display screen. This configuration will be described below.
　（表示装置の処理）
　本実施形態では、表示処理部１４は、判定部１６からの指示に基づき、映像内の識別用画像が無効である旨を示すコーションを表示部１８に表示させる。表示部１８は表示処理部１４からの指示を受けると、映像内の識別用画像が無効である旨を示すコーションを表示画面に表示する。 (Processing of display device)
In the present embodiment, the display processing unit 14 causes the display unit 18 to display a caution indicating that the identification image in the video is invalid based on an instruction from the determination unit 16. Upon receiving an instruction from the display processing unit 14, the display unit 18 displays a caution indicating that the identification image in the video is invalid on the display screen.
　この処理について、図１５及び図１６に基づいて具体的に説明する。ここで、図１５は、本実施形態に係る表示装置の表示画面の一表示例を示す図であり、図１６は、本実施形態に係る表示装置１の処理手順を示すフロー図である。 This process will be specifically described with reference to FIGS. 15 and 16. Here, FIG. 15 is a diagram illustrating a display example of the display screen of the display device according to the present embodiment, and FIG. 16 is a flowchart illustrating a processing procedure of the display device 1 according to the present embodiment.
　はじめに、Ｓ３１～Ｓ３３までの処理は、実施形態１の図５におけるＳ１１～Ｓ１３と同じであるので、ここではその説明を省略する。以下では、Ｓ３４以降の処理について説明する。 First, since the processes from S31 to S33 are the same as S11 to S13 in FIG. 5 of the first embodiment, the description thereof is omitted here. Below, the process after S34 is demonstrated.
　判定部１６がＱＲコード５０は無効であると判定すると（Ｓ３４：ＮＯ）、判定部１６は、ＱＲコード５０が無効である旨を示すコーションを表示するように表示処理部１４に指示する。表示処理部１４は、判定部１６からの指示に基づき、映像内のＱＲコード５０が無効である旨のコーションを表示部１８に表示させる。そして、表示部１８は、図１５に示すように、映像内のＱＲコード５０が無効である旨を示すコーション５５を表示画面４０に表示する（Ｓ３６）。本図では、映像内のＱＲコード５０が無効である旨を示すコーションとして、「ＱＲコードは無効です。」というコーション５５を表示している。 If the determination unit 16 determines that the QR code 50 is invalid (S34: NO), the determination unit 16 instructs the display processing unit 14 to display a caution indicating that the QR code 50 is invalid. Based on an instruction from the determination unit 16, the display processing unit 14 causes the display unit 18 to display a caution that the QR code 50 in the video is invalid. Then, as shown in FIG. 15, the display unit 18 displays a caution 55 indicating that the QR code 50 in the video is invalid on the display screen 40 (S36). In this figure, a caution 55 “QR code is invalid” is displayed as a caution indicating that the QR code 50 in the video is invalid.
　一方、判定部１６がＱＲコード５０は有効であると判定した場合には（Ｓ３４：ＹＥＳ）、判定部１６は、表示処理部１４に何の指示も与えない。したがって、この場合には、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる（Ｓ３５）。 On the other hand, when the determination unit 16 determines that the QR code 50 is valid (S34: YES), the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, in this case, the display processing unit 14 causes the display unit 18 to display the video supplied to the display processing unit 14 as it is (S35).
　以上のように、本実施形態によれば、映像内のＱＲコード５０が有効でない、すなわちＱＲコード５０が無効である場合には、ＱＲコード５０が無効である旨のコーション５５が表示画面４０に表示される。そのため、ユーザは、表示画面上に表示されたコーション５５を見れば、当該ＱＲコード５０が無効であることが一目で分かる。したがって、本実施形態によれば、映像に含まれる無効なＱＲコード５０によってユーザが混乱するのを防止できる。 As described above, according to the present embodiment, when the QR code 50 in the video is not valid, that is, when the QR code 50 is invalid, a caution 55 indicating that the QR code 50 is invalid is displayed on the display screen 40. Is displayed. Therefore, the user can recognize at a glance that the QR code 50 is invalid by looking at the caution 55 displayed on the display screen. Therefore, according to the present embodiment, the user can be prevented from being confused by the invalid QR code 50 included in the video.
　なお、図１５では、コーションとして「ＱＲコードは無効です。」というコーション５５を表示している。しかしながら、コーションは、識別用画像が無効であるとユーザが認識できるような内容であれば、特に限定されるものではない。 In FIG. 15, a caution 55 “QR code is invalid” is displayed as a caution. However, the caution is not particularly limited as long as the user can recognize that the identification image is invalid.
　また、以上では、識別用画像がＱＲコードである場合を例に挙げているが、識別用画像はＱＲコードに限定されず、他の種類の識別用画像であってもよい。 In the above description, the identification image is a QR code. However, the identification image is not limited to a QR code, and may be another type of identification image.
　〔第５の実施形態〕
　上述したように、第３の実施形態では、無効な識別用画像に埋め込まれたデータを抽出できないようにするための識別不可能化画像を表示する構成を示し、第４の実施形態では、識別用画像が無効である旨のコーションを表示画面に表示する構成を示したが、本発明はこれらに限定されるわけではない。例えば、無効な識別用画像の代わりに代替の識別用画像を表示してもよい。この構成について以下に説明する。なお、代替の識別用画像とは、識別用画像に埋め込まれている情報とは異なる代替の情報が埋め込まれた識別用画像を意味する。代替の情報とは、例えば代替のリンク先を示すリンク先情報等である。 [Fifth Embodiment]
As described above, in the third embodiment, a configuration for displaying a non-identifiable image for preventing extraction of data embedded in an invalid identification image is shown. In the fourth embodiment, identification is performed. Although the configuration in which the caution indicating that the work image is invalid is displayed on the display screen, the present invention is not limited to this. For example, an alternative identification image may be displayed instead of an invalid identification image. This configuration will be described below. The alternative identification image means an identification image in which alternative information different from the information embedded in the identification image is embedded. The alternative information is, for example, link destination information indicating an alternative link destination.
　（表示装置の処理）
　本実施形態では、表示処理部１４は、判定部１６からの指示に基づき、映像内の識別用画像の代わりに代替の識別用画像を表示部１８に表示させる。表示部１８は表示処理部１４からの指示を受けると、映像内の識別用画像の代わりに代替の識別用画像を表示する。ここで、「映像内の識別用画像の代わりに代替の識別用画像を表示する」とは、
・代替の識別用画像を識別用画像の上に重畳した映像を表示すること
・識別用画像を代替の識別用画像に置き換えた映像を表示すること
を少なくとも含む。 (Processing of display device)
In the present embodiment, the display processing unit 14 causes the display unit 18 to display an alternative identification image instead of the identification image in the video based on an instruction from the determination unit 16. Upon receiving an instruction from the display processing unit 14, the display unit 18 displays an alternative identification image instead of the identification image in the video. Here, “displaying an alternative identification image instead of the identification image in the video” means
Displaying at least a video obtained by superimposing an alternative identification image on the identification image. Displaying at least a video obtained by replacing the identification image with the alternative identification image.
　すなわち、表示処理部１４は、代替の識別用画像を識別用画像の上に重畳した映像を表示部１８に表示させてもよいし、識別用画像を代替の識別用画像に置き換えた映像を表示部１８に表示させてもよく、ユーザが識別用画像の代わりに代替の識別用画像を視認できれば代替の識別用画像の表示方法に特に限定はない。 In other words, the display processing unit 14 may cause the display unit 18 to display a video in which an alternative identification image is superimposed on the identification image, or display a video in which the identification image is replaced with an alternative identification image. The display method may be displayed on the unit 18, and the display method of the alternative identification image is not particularly limited as long as the user can visually recognize the alternative identification image instead of the identification image.
　この処理について、図１７及び図１８に基づいて具体的に説明する。ここで、図１７は、本実施形態に係る表示装置の表示画面の一表示例を示す図であり、図１８は、本実施形態に係る表示装置１の処理手順を示すフロー図である。 This process will be specifically described with reference to FIGS. 17 and 18. Here, FIG. 17 is a diagram illustrating a display example of the display screen of the display device according to the present embodiment, and FIG. 18 is a flowchart illustrating a processing procedure of the display device 1 according to the present embodiment.
　はじめに、Ｓ４１～Ｓ４３までの処理は、実施形態１の図５におけるＳ１１～Ｓ１３と同じであるので、ここではその説明を省略する。以下では、Ｓ４４以降の処理について説明する。 First, since the processing from S41 to S43 is the same as S11 to S13 in FIG. 5 of the first embodiment, the description thereof is omitted here. Below, the process after S44 is demonstrated.
　判定部１６がＱＲコード５０は無効であると判定すると（Ｓ４４：ＮＯ）、判定部１６は、ＱＲコード５０の代わりに代替の識別用画像を表示するように表示処理部１４に指示する。表示処理部１４は、判定部１６からの指示に基づき、映像内のＱＲコード５０の代わりに代替のＱＲコードを表示部１８に表示させる。そして、表示部１８は、図１７の（ａ）に示すように、映像内のＱＲコード５０の代わりに代替のＱＲコード６０を表示画面に表示する（Ｓ４６）。 If the determination unit 16 determines that the QR code 50 is invalid (S44: NO), the determination unit 16 instructs the display processing unit 14 to display an alternative identification image instead of the QR code 50. Based on the instruction from the determination unit 16, the display processing unit 14 causes the display unit 18 to display an alternative QR code instead of the QR code 50 in the video. Then, as shown in FIG. 17A, the display unit 18 displays an alternative QR code 60 on the display screen instead of the QR code 50 in the video (S46).
　このとき、ユーザがＱＲコード６０をスマートフォン等で読み取れば、例えば図１７の（ｂ）に示すように、ＱＲコード６０に対応する代替のサイトが提供する表示画像が表示され、代替のサイトにアクセスできるように構成されている。本図では、ＱＲコード６０に対応するＵＲＬのサイトは、ＱＲコード５０に対応するＵＲＬが無効である旨を示す代替サイトとなっている。 At this time, if the user reads the QR code 60 with a smartphone or the like, for example, as shown in FIG. 17B, a display image provided by an alternative site corresponding to the QR code 60 is displayed, and the alternative site is accessed. It is configured to be able to. In this figure, the URL site corresponding to the QR code 60 is an alternative site indicating that the URL corresponding to the QR code 50 is invalid.
　一方、判定部１６がＱＲコード５０は有効であると判定した場合には（Ｓ４４：ＹＥＳ）、判定部１６は、表示処理部１４に何の指示も与えない。したがって、この場合には、表示処理部１４は、表示処理部１４に供給された映像をそのまま表示部１８に表示させる（Ｓ４５）。 On the other hand, when the determination unit 16 determines that the QR code 50 is valid (S44: YES), the determination unit 16 does not give any instruction to the display processing unit 14. Therefore, in this case, the display processing unit 14 displays the video supplied to the display processing unit 14 on the display unit 18 as it is (S45).
　以上のように、本実施形態によれば、映像内のＱＲコードが有効でない、すなわちＱＲコード５０が無効である場合には、ＱＲコード５０の代わりに代替のＱＲコード６０が表示画面４０に表示される。例えば、図１７の（ｂ）に示したように、ＱＲコード６０に対応するＵＲＬのサイトを、ＱＲコード５０に対応するＵＲＬが無効である旨を示す代替サイトにすることにより、ＱＲコード５０に対応するＵＲＬが無効であることをユーザが認識できる。このように、ユーザは、代替のＱＲコード６０を介して、当該ＱＲコード５０が無効であることを認識することができる。したがって、本実施形態によれば、映像に含まれる無効なＱＲコード５０によってユーザが混乱するのを防止できる。 As described above, according to the present embodiment, when the QR code in the video is not valid, that is, when the QR code 50 is invalid, the alternative QR code 60 is displayed on the display screen 40 instead of the QR code 50. Is done. For example, as shown in FIG. 17B, the URL site corresponding to the QR code 60 is changed to an alternative site indicating that the URL corresponding to the QR code 50 is invalid. The user can recognize that the corresponding URL is invalid. In this manner, the user can recognize that the QR code 50 is invalid via the alternative QR code 60. Therefore, according to the present embodiment, the user can be prevented from being confused by the invalid QR code 50 included in the video.
　なお、以上では、識別用画像及び代替の識別用画像がＱＲコードである場合を例に挙げているが、識別用画像及び代替の識別用画像はＱＲコードに限定されず、他の種類の識別用画像であってもよい。 In the above, the case where the identification image and the alternative identification image are QR codes is taken as an example, but the identification image and the alternative identification image are not limited to QR codes, and other types of identification It may be an image for use.
