　（重畳部）
　重畳部１２２は、コマ画像を複数の部分画像に分割する。また、重畳部１２２は、部分画像に分割したコマ画像にモザイク化オブジェクトを重畳する。 (Superimposed part)
The superimposing unit 122 divides the frame image into a plurality of partial images. The superimposing unit 122 superimposes the mosaic object on the frame image divided into the partial images.
　具体的には、重畳部１２２は、まず、グラフィックバッファ１０６に格納されているコマ画像を読み出し、読み出したコマ画像を配置参照用フレームに合わせて複数の部分画像に分割する。そして、分割した部分画像の各々に対して、逆モザイク化オブジェクトを構成する部分オブジェクトを重畳する。 Specifically, the superimposing unit 122 first reads the frame image stored in the graphic buffer 106 and divides the read frame image into a plurality of partial images according to the arrangement reference frame. Then, the partial objects constituting the inverse mosaic object are superimposed on each of the divided partial images.
　（モザイク化部）
　モザイク化部１２３は、部分画像同士の入れ替え（モザイク化）によってモザイク化画像を生成する手段である。すなわち、モザイク化部１２３は、重畳部１２２と共にモザイク化手段として機能し、モザイク化処理を実行する。 (Mosaic Division)
The mosaic unit 123 is means for generating a mosaic image by exchanging partial images (mosaicing). That is, the mosaic unit 123 functions as a mosaic unit together with the superimposing unit 122 and executes the mosaic process.
　具体的には、モザイク化部１２３は、コマ画像に逆モザイク化オブジェクトが重畳された画像（重畳コマ画像とも記載する）を重畳部１２２から取得し、配置テーブルを参照して取得した重畳コマ画像から重畳モザイク化画像を生成する。 Specifically, the mosaicing unit 123 obtains an image (also referred to as a superimposed frame image) obtained by superimposing an inverse mosaic object on a frame image from the superposition unit 122, and obtains the superimposed frame image obtained by referring to the arrangement table. A superimposed mosaic image is generated.
　モザイク化処理部１２０は、上述のように、逆モザイク化部１２１、重畳部１２２、及び、モザイク化部１２３において、オブジェクトがモザイク化された画像上の特定の位置に重畳された重畳モザイク化画像を生成する。 As described above, the mosaic processing unit 120 uses the inverse mosaicing unit 121, the superimposing unit 122, and the mosaicing unit 123 to superimpose a mosaiced image in which an object is superimposed at a specific position on a mosaiced image. Is generated.
　なお、モザイク化処理部１２０の重畳部１２２は、転送部１０５によってグラフィックバッファ１０６にコマ画像が１Ｖ周期で逐次格納される場合には、当該コマ画像を１Ｖ周期で逐次取得してもよいし、１Ｖ周期の整数倍の周期で逐次取得してもよい。この場合には、逆モザイク化部１２１もまた、オブジェクトバッファ１０７からオブジェクトを１Ｖ周期、又は、１Ｖ周期の整数倍の周期で逐次取得すればよい。 Note that the superimposing unit 122 of the mosaic processing unit 120 may sequentially acquire the frame image in 1V cycle when the transfer unit 105 sequentially stores the frame image in the graphic buffer 106 in 1V cycle. You may acquire sequentially with the period of the integral multiple of 1V period. In this case, the inverse mosaicing unit 121 may also sequentially acquire objects from the object buffer 107 at a cycle of 1V or an integer multiple of 1V.
　また、重畳部１２２は、転送部１０５によってグラフィックバッファ１０６にコマ画像が１Ｖ周期の整数倍の周期で逐次格納される場合には、１Ｖ周期の整数倍の周期で逐次取得すればよい。この場合には、逆モザイク化部１２１もまた、オブジェクトバッファ１０７からオブジェクトを１Ｖ周期の整数倍の周期で逐次取得すればよい。 Further, when the frame image is sequentially stored in the graphic buffer 106 by the transfer unit 105 in a cycle that is an integral multiple of 1V cycle, the superimposing unit 122 may acquire the image sequentially in a cycle that is an integral multiple of 1V cycle. In this case, the inverse mosaicing unit 121 may also sequentially acquire objects from the object buffer 107 at a cycle that is an integral multiple of 1V cycle.
　モザイク化画像が例えばパズルゲームである場合、モザイク化処理部１２０の各部は、コマ画像及びオブジェクトを１Ｖ周期で逐次取得してパズルゲームを生成することにより、パズルゲームをスムーズな動画像により実現することができる。一方、モザイク化処理部１２０の各部は、コマ画像及びオブジェクトを１Ｖ周期の整数倍の周期で逐次取得してパズルゲームを生成することで、当該モザイク化処理部１２０を含むテレビ１０におけるパズルゲームの生成に関する処理の負荷を軽減することができる。 When the mosaic image is, for example, a puzzle game, each unit of the mosaic processing unit 120 generates the puzzle game by sequentially acquiring the frame image and the object in 1V cycle, thereby realizing the puzzle game with a smooth moving image. be able to. On the other hand, each part of the mosaic processing unit 120 sequentially acquires frame images and objects at a cycle that is an integer multiple of the 1V cycle to generate a puzzle game, thereby generating a puzzle game on the television 10 including the mosaic processing unit 120. It is possible to reduce the processing load related to generation.
　〔重畳モザイク化画像生成処理〕
　次に、本実施形態に係るモザイク化処理部１２０における重畳モザイク化画像生成処理について、図４及び図５を参照して説明する。なお、本実施形態では、モザイク化画像がパズルゲームであり、パズルゲームに重畳して表示されるオブジェクトが文字スーパー（図４及び図５に示す例では、緊急地震速報）である場合について説明する。図４は、本実施形態に係るテレビ１０の備えるモザイク化処理部１２０における重畳モザイク化画像生成処理の流れを示すフローチャートである。 [Superimposed mosaic image generation processing]
Next, the superimposed mosaic image generation processing in the mosaic processing unit 120 according to the present embodiment will be described with reference to FIGS. 4 and 5. In the present embodiment, a case will be described in which a mosaic image is a puzzle game, and an object superimposed and displayed on the puzzle game is a character super (in the example shown in FIGS. 4 and 5, an earthquake early warning). . FIG. 4 is a flowchart showing a flow of the superimposed mosaic image generation process in the mosaic processing unit 120 included in the television 10 according to the present embodiment.
　また、図５は、本実施形態に係る重畳モザイク化画像生成処理の流れを模式的に示す図である。図５（ａ）は重畳モザイク化画像生成処理が施される前のコマ画像及び文字スーパーの一例を示し、（ｂ）は逆モザイク化された文字スーパーの一例を示し、（ｃ）は逆モザイク化された文字スーパーが重畳された重畳コマ画像の一例を示し、（ｄ）は重畳モザイク化画像生成処理の施された重畳モザイク化画像の一例を示す。 FIG. 5 is a diagram schematically showing the flow of the superimposed mosaic image generation process according to this embodiment. FIG. 5A shows an example of a frame image and a character super before the superimposed mosaic image generation processing is performed, FIG. 5B shows an example of a character super image that has been demosaiced, and FIG. 5C shows an inverse mosaic. An example of the superimposed frame image on which the converted character superimposition is superimposed is shown, and (d) shows an example of the superimposed mosaic image that has been subjected to the superimposed mosaic image generation process.
　モザイク化処理部１２０は、パズルゲームを表示する旨のユーザ指示を示すリモコン信号（単にパズル表示指示とも記載する）を受け付けると、図４に示すモザイク化画像生成処理を開始する。 When the mosaic processing unit 120 receives a remote control signal indicating a user instruction to display the puzzle game (also simply referred to as a puzzle display instruction), the mosaic processing unit 120 starts the mosaic image generation process shown in FIG.
　図４に示すように、モザイク化処理部１２０は、パズル表示指示を取得すると、まず、配置参照用フレームとして、取得したパズル表示指示において指定されているパズルゲームと関連付けられているパズル用フレームを、記憶部（不図示）から読み出す（ステップＳ１０１）。ここで、不図示の記憶部には、複数のパズルゲームの各々に対して、各パズルゲームに対応するフレームであって各パズルゲームを構成する部分画像を配置するための複数のブロックを有するパズル用フレームが関連づけて格納されている。 As illustrated in FIG. 4, when the mosaic processing unit 120 acquires the puzzle display instruction, first, as the arrangement reference frame, the puzzle frame associated with the puzzle game specified in the acquired puzzle display instruction is displayed. The data is read from a storage unit (not shown) (step S101). Here, in a storage unit (not shown), a puzzle having a plurality of blocks for arranging a partial image constituting each puzzle game, which is a frame corresponding to each puzzle game, for each of the plurality of puzzle games. Frames are stored in association with each other.
　モザイク化処理部１２０は、パズル用フレームを読み出すと、部分画像の何れを、パズル用フレームの何れのブロックに配置するかを決定するための配置テーブルを生成する（ステップＳ１０２）。モザイク化処理部１２０は、配置テーブルを毎回ランダムに決定してもよいし、パズル表示指示においてパズルゲームの難易度が指定されている場合には指定された難易度に応じて決定してもよい。なお、配置テーブルの詳細については図面を変えて後述する。 When the mosaic processing unit 120 reads out the puzzle frame, the mosaic processing unit 120 generates an arrangement table for determining which of the partial images is arranged in which block of the puzzle frame (step S102). The mosaic processing unit 120 may determine the arrangement table at random each time, or may determine according to the designated difficulty level when the difficulty level of the puzzle game is designated in the puzzle display instruction. . Details of the arrangement table will be described later with different drawings.
　次に、モザイク化処理部１２０の備える逆モザイク化部１２１は、オブジェクトバッファ１０７に格納されている文字スーパーを読み出し、パズル用フレームの有するブロックに配置可能なように複数の部分オブジェクトに分割する（ステップＳ１０３）。逆モザイク化部１２１は、例えば、パズル用フレームが４行４列の１６個のブロックを有している場合には、図５（ａ）に示すように、文字スーパーを、４行４列の１６個のブロックからなる部分オブジェクトに分割する。 Next, the de-mosaicing unit 121 included in the mosaicing processing unit 120 reads the character superposition stored in the object buffer 107 and divides it into a plurality of partial objects so that they can be arranged in blocks of the puzzle frame ( Step S103). For example, when the puzzle frame has 16 blocks of 4 rows and 4 columns, the inverse mosaicing unit 121 converts the character supers of 4 rows and 4 columns as shown in FIG. Divide into partial objects consisting of 16 blocks.
　文字スーパーを部分オブジェクトに分割すると、逆モザイク化部１２１は、配置テーブルを参照し、図５（ｂ）に示すような、部分オブジェクトをパズル用フレームの対応するブロックに配置（逆モザイク化処理）した逆モザイク化オブジェクトを生成する（ステップＳ１０４）。 When the character super is divided into partial objects, the de-mosaic unit 121 refers to the arrangement table and arranges the partial objects in the corresponding blocks of the puzzle frame as shown in FIG. 5B (de-mosaic processing). The generated inverse mosaiced object is generated (step S104).
　逆モザイク化オブジェクトが生成されると、モザイク化処理部１２０の備える重畳部１２２は、グラフィックバッファ１０６に格納されているコマ画像を取得し、取得したコマ画像をパズル用フレームの有するブロックに配置可能なように複数の部分画像に分割する（ステップＳ１０５）。 When the de-mosaic object is generated, the superimposing unit 122 included in the mosaic processing unit 120 can acquire the frame image stored in the graphic buffer 106 and can arrange the acquired frame image in the block of the puzzle frame. In this manner, the image is divided into a plurality of partial images (step S105).
　部分画像を生成すると、重畳部１２２は、逆モザイク化オブジェクトを、部分画像に分割されたコマ画像に重畳する（ステップＳ１０６）。このとき、逆モザイク化オブジェクトが重畳された部分画像は、例えば、図５（ｃ）に示すようになる。 When the partial image is generated, the superimposing unit 122 superimposes the inverse mosaic object on the frame image divided into the partial images (step S106). At this time, the partial image on which the inverse mosaicked object is superimposed is, for example, as shown in FIG.
　逆モザイク化オブジェクトが部分画像に重畳されると、モザイク化部１２３は、配置テーブルを参照し、部分画像をパズル用フレームの対応するブロックに配置（モザイク化処理）し、重畳モザイク化画像を生成する（ステップＳ１０７）。重畳モザイク化画像は、例えば、図５（ｄ）に示すようになる。 When the de-mosaic object is superimposed on the partial image, the mosaicing unit 123 refers to the arrangement table, arranges the partial image in a corresponding block of the puzzle frame (mosaicing process), and generates a superimposed mosaic image (Step S107). The superimposed mosaic image is, for example, as shown in FIG.
　このとき、部分画像には逆モザイク化オブジェクトが重畳されているため、モザイク化部１２３において生成されたモザイク化画像には、モザイク化により逆モザイク化処理の施される前の状態に戻ったオブジェクトが重畳されることになる。すなわち、モザイク化部１２３によって生成されるモザイク化画像は、重畳モザイク化画像となる。 At this time, since the de-mosaic object is superimposed on the partial image, the mosaic image generated in the mosaic unit 123 is an object that has returned to the state before being subjected to the de-mosaic process due to the mosaic process. Will be superimposed. That is, the mosaic image generated by the mosaic unit 123 is a superimposed mosaic image.
　上述のように、逆モザイク化部１２１は、ステップＳ１０３～Ｓ１０４の処理を実行することにより、逆モザイク化処理を実行する。また、重畳部１２２及びモザイク化部１２３は、ステップＳ１０５～Ｓ１０７の処理を実行することにより、モザイク化処理を実行する。 As described above, the de-mosaic unit 121 performs the de-mosaic process by performing the processes of steps S103 to S104. Further, the superimposing unit 122 and the mosaicing unit 123 execute the mosaicing process by executing the processes of steps S105 to S107.
　なお、モザイク化処理部１２０は、上述のようにしてパズルゲームを生成した後は、グラフィックバッファに逐次格納されるコマ画像を逐次取得してステップＳ１０２からステップＳ１０７までの処理を繰り返し実行する。これにより、各ブロックに配置される部分画像が逐次更新されるため、パズルゲームを動画像により実現することができる。 Note that, after generating the puzzle game as described above, the mosaic processing unit 120 sequentially acquires the frame images sequentially stored in the graphic buffer and repeatedly executes the processing from step S102 to step S107. Thereby, since the partial image arrange | positioned at each block is updated sequentially, a puzzle game is realizable with a moving image.
　（配置テーブル）
　次に、配置テーブルについて、図６を参照して説明する。図６は、本実施形態に係るモザイク化処理部１２０において生成される配置テーブルの一例を示す図である。 (Arrangement table)
Next, the arrangement table will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of an arrangement table generated in the mosaic processing unit 120 according to the present embodiment.
　パズル表示指示において指定されているパズルゲームに関連付けられているパズル用フレームが、例えば、パズル用フレームが４行４列の１６個のブロックを有する場合、図６に示すように、各ブロックには、０～９及びＡ～Ｆのブロックナンバー（図６に示す「ブロックＮｏ」）が与えられている。 For example, when the puzzle frame associated with the puzzle game specified in the puzzle display instruction has 16 blocks of 4 rows and 4 columns, as shown in FIG. , 0 to 9 and A to F are given block numbers (“Block No” shown in FIG. 6).
　また、モザイク化処理部１２０は、パズル用フレームに合わせて分割した部分画像の各々に対して、該部分画像と対応する位置のブロックに与えられているブロックナンバーと同じ値の部分画像ナンバーを付す。 Further, the mosaic processing unit 120 attaches a partial image number having the same value as the block number given to the block at the position corresponding to the partial image to each partial image divided in accordance with the puzzle frame. .
　そして、モザイク化処理部１２０は、或るブロックに配置されている部分画像と他のブロックに配置されている部分画像とを入れ替え、図６に示すように、各ブロックと、各ブロックに配置される部分画像とが関連付けられた配置テーブルを生成する。図６に示す配置テーブルでは、ブロックナンバーが「０」のブロックに部分画像ナンバーが「０」の部分画像が配置され、ブロックナンバーが「１」のブロックに部分画像ナンバーが「Ａ」の部分画像が配置されることになる。 Then, the mosaic processing unit 120 replaces the partial image arranged in a certain block with the partial image arranged in another block, and is arranged in each block and each block as shown in FIG. An arrangement table associated with the partial image to be generated is generated. In the arrangement table shown in FIG. 6, the partial image with the partial image number “0” is arranged in the block with the block number “0”, and the partial image with the partial image number “A” in the block with the block number “1”. Will be placed.
　モザイク化処理部１２０は、上述のようにして、配置テーブルを参照して部分画像を対応する各ブロックに配置したパズル用コマ画像を含むグラフィックプレーンを生成し、表示制御部１０９に供給する。なお、生成された配置テーブルは、記憶部（不図示）に格納されればよい。 As described above, the mosaic processing unit 120 generates a graphic plane including the puzzle frame images in which the partial images are arranged in the corresponding blocks with reference to the arrangement table, and supplies the graphic plane to the display control unit 109. The generated arrangement table may be stored in a storage unit (not shown).
　（逆モザイク化処理）
　ここで、逆モザイク化処理の具体的な流れについて、図５を参照して説明する。なお、図５（ａ）に示すように、パズル用フレームに合わせて分割した部分オブジェクトの各々に対して、該部分オブジェクトと対応する位置のブロックに与えられているブロックナンバーと同じ値の部分オブジェクトナンバーが付されている。以降では、部分オブジェクトナンバーが「０」の部分オブジェクトを、単に部分オブジェクト「０」とも記載し、部分画像ナンバーが「０」の部分画像を、単に部分画像「０」とも記載し、ブロックナンバーが「０」のブロックを、単にブロック「０」とも記載する。 (Reverse mosaic processing)
Here, a specific flow of the inverse mosaic processing will be described with reference to FIG. As shown in FIG. 5A, for each partial object divided in accordance with the puzzle frame, the partial object having the same value as the block number given to the block at the position corresponding to the partial object. Numbered. Hereinafter, the partial object with the partial object number “0” is also simply referred to as the partial object “0”, the partial image with the partial image number “0” is simply referred to as the partial image “0”, and the block number is The block “0” is also simply referred to as block “0”.
　逆モザイク化部１２１は、上述したように、重畳モザイク化画像生成処理のステップＳ１０４において、配置テーブルを参照して逆モザイク化オブジェクトを生成する逆モザイク化処理を実行する。このとき、逆モザイク化部１２１は、図５（ｄ）に示す重畳モザイク化画像のように、重畳モザイク化画像がモザイク化により逆モザイク化処理の施される前の状態に戻ったオブジェクトが重畳された画像となるように逆モザイク化オブジェクトを生成する。 As described above, the de-mosaicing unit 121 executes the de-mosaic process for generating the de-mosaic object with reference to the arrangement table in step S104 of the superimposed mosaic image generation process. At this time, the inverse mosaicing unit 121 superimposes the object that has returned to the state before the inverse mosaicing process is performed by mosaicing the superimposed mosaiced image, as in the superimposed mosaiced image illustrated in FIG. A de-mosaic object is generated so as to obtain a processed image.
　図５に示す一例では、逆モザイク化部１２１は、（ａ）に示す部分オブジェクト「１」を、（ｄ）に示すようにモザイク化部１２３によるモザイク化処理において部分画像「Ａ」に重畳（換言すれば、ブロック「１」に再配置）されるよう、（ｂ）に示すようにブロック「Ａ」に配置する。 In the example illustrated in FIG. 5, the inverse mosaicing unit 121 superimposes the partial object “1” illustrated in (a) on the partial image “A” in the mosaic processing by the mosaicing unit 123 as illustrated in (d) ( In other words, it is arranged in the block “A” as shown in (b) so as to be rearranged in the block “1”.
　同様にして、逆モザイク化部１２１は、部分オブジェクト「０」、「２」～「９」及び「Ａ」～「Ｆ」を、逆モザイク化処理において次のように配置する。
・部分オブジェクト「０」を、部分画像「０」に重畳させるため、ブロック「０」に配置・部分オブジェクト「２」を、部分画像「Ｄ」に重畳させるため、ブロック「Ｄ」に配置・部分オブジェクト「３」を、部分画像「２」に重畳させるため、ブロック「２」に配置・部分オブジェクト「４」を、部分画像「５」に重畳させるため、ブロック「５」に配置・部分オブジェクト「５」を、部分画像「Ｂ」に重畳させるため、ブロック「Ｂ」に配置・部分オブジェクト「６」を、部分画像「Ｆ」に重畳させるため、ブロック「Ｆ」に配置・部分オブジェクト「７」を、部分画像「４」に重畳させるため、ブロック「４」に配置・部分オブジェクト「８」を、部分画像「３」に重畳させるため、ブロック「３」に配置・部分オブジェクト「９」を、部分画像「６」に重畳させるため、ブロック「６」に配置・部分オブジェクト「Ａ」を、部分画像「１」に重畳させるため、ブロック「１」に配置・部分オブジェクト「Ｂ」を、部分画像「７」に重畳させるため、ブロック「７」に配置・部分オブジェクト「Ｃ」を、部分画像「８」に重畳させるため、ブロック「８」に配置・部分オブジェクト「Ｄ」を、部分画像「９」に重畳させるため、ブロック「９」に配置・部分オブジェクト「Ｅ」を、部分画像「Ｃ」に重畳させるため、ブロック「Ｃ」に配置・部分オブジェクト「Ｆ」を、部分画像「Ｅ」に重畳させるため、ブロック「Ｅ」に配置
　このようにして、逆モザイク化部１２１において、図５（ｂ）に示すような逆モザイク化オブジェクトが生成される。 Similarly, the de-mosaicing unit 121 arranges the partial objects “0”, “2” to “9” and “A” to “F” as follows in the de-mosaic process.
-Place the partial object "0" on the block "0" to be superimposed on the partial image "0"-Place the partial object "2" on the block "D" to superimpose the partial object "2" on the partial image "D" In order to superimpose the object “3” on the partial image “2”, the arrangement / partial object “4” is placed on the block “5” in order to superimpose the arrangement / partial object “4” on the block “2”. In order to superimpose 5 ”on the partial image“ B ”, the arrangement / partial object“ 6 ”on the block“ B ”is superimposed on the partial image“ F ”. Is superimposed on the partial image “4”, the arrangement / partial object “8” is superimposed on the block “4”, and the arrangement / partial object “9” is superimposed on the block “3”. In order to superimpose on the partial image “6”, the arrangement / partial object “A” is superimposed on the block “6”, and on the partial image “1”, the arrangement / partial object “B” is superimposed on the block “1”. In order to superimpose on “7”, the arrangement / partial object “C” is superimposed on the block “7”, and on the partial image “8”, the arrangement / partial object “D” is placed on the block “8” and the partial image “9”. ”Is placed on the block“ 9 ”, and the placement / partial object“ F ”is placed on the block“ C ”, and the placement / partial object“ F ”is placed on the partial image“ E ”. Arranged in block “E” for superposition In this way, the inverse mosaicing unit 121 generates an inverse mosaiced object as shown in FIG.
　（モザイク化処理）
　次に、モザイク化処理の具体的な流れについて、図５を参照して説明する。 (Mosaic processing)
Next, a specific flow of the mosaic processing will be described with reference to FIG.
　モザイク化部１２３は、上述したように、重畳モザイク化画像生成処理のステップＳ１０７において、配置テーブルを参照して重畳モザイク化画像を生成するモザイク化処理を生成する。このとき、モザイク化部１２３は、図５（ｃ）に示すモザイク化オブジェクトの重畳されたコマ画像をモザイク化することにより、図５（ｄ）に示す重畳モザイク化画像を生成する。 As described above, in step S107 of the superimposed mosaic image generation process, the mosaic unit 123 generates a mosaic process that generates a superimposed mosaic image with reference to the arrangement table. At this time, the mosaic unit 123 generates a superimposed mosaic image shown in FIG. 5D by mosaicing the frame image on which the mosaic object shown in FIG. 5C is superimposed.
　図５に示す一例では、モザイク化部１２３は、モザイク化処理により、（ｃ）に示す部分オブジェクト「Ａ」が重畳された部分画像「１」を、（ｄ）に示すようにブロック「Ａ」に配置する。 In the example illustrated in FIG. 5, the mosaic unit 123 converts the partial image “1” on which the partial object “A” illustrated in (c) is superimposed into a block “A” as illustrated in FIG. To place.
　同様にして、モザイク化部１２３は、部分画像「０」、「２」～「９」及び「Ａ」～「Ｆ」を、モザイク化処理において次のように配置する。
・部分オブジェクト「０」が重畳された部分画像「０」を、ブロック「０」に配置
・部分オブジェクト「３」が重畳された部分画像「２」を、ブロック「３」に配置
・部分オブジェクト「８」が重畳された部分画像「３」を、ブロック「８」に配置
・部分オブジェクト「７」が重畳された部分画像「４」を、ブロック「７」に配置
・部分オブジェクト「４」が重畳された部分画像「５」を、ブロック「４」に配置
・部分オブジェクト「９」が重畳された部分画像「６」を、ブロック「９」に配置
・部分オブジェクト「Ｂ」が重畳された部分画像「７」を、ブロック「Ｂ」に配置
・部分オブジェクト「Ｃ」が重畳された部分画像「８」を、ブロック「Ｃ」に配置
・部分オブジェクト「Ｄ」が重畳された部分画像「９」を、ブロック「Ｄ」に配置
・部分オブジェクト「１」が重畳された部分画像「Ａ」を、ブロック「１」に配置
・部分オブジェクト「５」が重畳された部分画像「Ｂ」を、ブロック「５」に配置
・部分オブジェクト「Ｅ」が重畳された部分画像「Ｃ」を、ブロック「Ｅ」に配置
・部分オブジェクト「２」が重畳された部分画像「Ｄ」を、ブロック「２」に配置
・部分オブジェクト「Ｆ」が重畳された部分画像「Ｅ」を、ブロック「Ｆ」に配置
・部分オブジェクト「６」が重畳された部分画像「Ｆ」を、ブロック「６」に配置
　このようにして、モザイク化部１２３において、図５（ｄ）に示すような重畳モザイク化画像が生成される。 Similarly, the mosaic unit 123 arranges the partial images “0”, “2” to “9”, and “A” to “F” as follows in the mosaic processing.
The partial image “0” on which the partial object “0” is superimposed is arranged on the block “0”. The partial image “2” on which the partial object “3” is superimposed is arranged on the block “3”. Partial image “3” with 8 superimposed thereon, partial image “4” with placement / partial object “7” superimposed on block “8”, and placement / partial object “4” overlaid on block “7” The partial image “5”, the partial image “6” in which the arrangement / partial object “9” is superimposed on the block “4”, and the partial image in which the arrangement / partial object “B” is superimposed on the block “9” “7”, a partial image “8” in which the arrangement / partial object “C” is superimposed on the block “B”, and a partial image “9” in which the arrangement / partial object “D” is superimposed on the block “C”. , Placed in block "D" The partial image “A” on which the partial object “1” is superimposed is placed on the block “1”, and the partial image “B” on which the partial object “5” is superimposed on the block “5”. ”Is superimposed on the block“ E ”, the partial image“ D ”on which the partial object“ 2 ”is superimposed on the block“ E ”, and the partial image“ F ”is superimposed on the block“ 2 ”. The partial image “E” is arranged in the block “F” and the partial image “F” in which the partial object “6” is superimposed is arranged in the block “6”. A superimposed mosaic image as shown in (d) is generated.
　なお、モザイク化画像を生成した後にオブジェクトを重畳した場合、より具体的には、表示制御部１０９においてオブジェクトバッファ１０７から読み出したオブジェクトをモザイク化画像に重畳した場合、表示制御部１０９における重畳処理が追いつかなくなる場合がある。これにより、オブジェクト又はモザイク化画像がちらついたり、オブジェクト又はモザイク化画像の一部分が欠落することにより、視認性が低下してしまうという問題が生じる場合がある。しかし、本実施形態に係るテレビ１０は、モザイクが画像自体の視認性が低下してしまうという問題を回避しつつ、重畳されるオブジェクトの視認性の低下を抑制することができる。 In addition, when an object is superimposed after generating a mosaic image, more specifically, when an object read from the object buffer 107 is superimposed on a mosaic image in the display control unit 109, the overlay process in the display control unit 109 is performed. You may not be able to catch up. As a result, there may be a problem that the visibility is lowered due to the flickering of the object or the mosaic image or the loss of a part of the object or the mosaic image. However, the television 10 according to the present embodiment can suppress the decrease in the visibility of the superimposed object while avoiding the problem that the visibility of the mosaic itself decreases.
　なお、本実施形態では、放送番組及び放送番組と独立して受信される文字スーパーから重畳モザイク化画像を生成する場合を例に挙げて説明したが、本発明はこれに限定されるものではない。 In the present embodiment, a case where a superimposed mosaic image is generated from a broadcast program and a character supertext received independently of the broadcast program has been described as an example. However, the present invention is not limited to this. .
　例えば、放送番組に代えて、テレビ１０に内蔵のＨＤＤに格納されている録画番組及び文字スーパーから重畳モザイク化画像を生成する構成を採用することもできる。また、ＤＶＤ及びＢＤなどの記録媒体に記録されているコンテンツ及び文字スーパーから重畳モザイク化画像を生成してもよい。なお、この場合には、テレビ１０は、ＤＶＤ又はＢＤを再生する再生部（不図示）を更に備えていればよい。 For example, instead of a broadcast program, a configuration in which a superimposed mosaic image is generated from a recorded program and a character superstore stored in an HDD built in the television 10 may be employed. Further, a superimposed mosaic image may be generated from content recorded on a recording medium such as a DVD and a BD and a character supermarket. In this case, the television 10 may further include a reproduction unit (not shown) that reproduces a DVD or a BD.
　一方、ＨＤＤ、ＤＶＤ又はＢＤなどに記録されているコンテンツを再生する再生装置がテレビ１０に外付けされる場合には、再生装置にモザイク化処理部１２０が備えられていることが好ましい。この場合には、画像表示装置が、ＨＤプレーヤ、ＤＶＤプレーヤ及びＢＤプレーヤなどの再生装置によって実現されることになる。なお、テレビ１０は、再生装置において生成されたモザイク化画像を該再生装置から取得すればよい。 On the other hand, when a playback device that plays back content recorded on an HDD, DVD, BD, or the like is externally attached to the television 10, it is preferable that the playback device includes a mosaic processing unit 120. In this case, the image display device is realized by a playback device such as an HD player, a DVD player, or a BD player. Note that the television 10 may acquire the mosaic image generated in the playback device from the playback device.
　＜変形例１＞
　本実施形態では、オブジェクトが文字スーパーである場合における重畳モザイク化画像の生成について説明したが、本発明はこれに限定されるものではなく、オブジェクトがパズルゲームにおいて部分画像を選択するためのカーソル及び矢印などであってもよい。 <Modification 1>
In the present embodiment, the generation of the superimposed mosaic image when the object is a character supermarket has been described. However, the present invention is not limited to this, and the cursor for selecting a partial image in the puzzle game and An arrow or the like may be used.
　本実施形態の変形例について、図７を参照して説明する。図７は、本実施形態の変形例に係るモザイク化画像生成処理の流れを模式的に示す図である。図７（ａ）は重畳モザイク化画像生成処理が施される前のコマ画像の一例を示し、（ｂ）は逆モザイク化されたカーソル及び矢印の一例を示し、（ｃ）は重畳モザイク化画像生成処理の施された重畳モザイク化画像の一例を示す。 A modification of this embodiment will be described with reference to FIG. FIG. 7 is a diagram schematically illustrating the flow of the mosaiced image generation process according to the modification of the present embodiment. FIG. 7A shows an example of a frame image before the superimposed mosaiced image generation processing is performed, FIG. 7B shows an example of a reverse mosaiced cursor and arrow, and FIG. 7C shows a superimposed mosaiced image. An example of a superimposed mosaic image that has been subjected to generation processing is shown.
　なお、図７（ｃ）に示すパズルゲームは、コマ画像が４行４列の合計１６枚に分割された部分画像を揃えるパズルゲームの一例である。具体的には、重畳モザイク化画像処理の施された画像において、或る１つのブロックに配置されている黒画像を該黒画像と隣接するブロックに配置されている部分画像のうちユーザに選択された選択部分画像と入れ替える操作を繰り返すことにより、モザイク化画像生成処理の施される前の画像に戻すパズルゲームである。 Note that the puzzle game shown in FIG. 7C is an example of a puzzle game in which partial images are divided into a total of 16 pieces of 4 rows and 4 columns. Specifically, in the image subjected to the superimposed mosaic image processing, the black image arranged in one block is selected by the user from the partial images arranged in the block adjacent to the black image. It is a puzzle game which returns to the image before a mosaic image generation process is performed by repeating the operation of replacing the selected partial image.
　本変形例に係るテレビ１０は、図７（ａ）に示すコマ画像を分割した部分画像にカーソル及び黒画像を重畳することにより、（ｃ）に示すようなパズルゲームを生成する。また、部分画像に重畳される黒画像には、図７（ｂ）、（ｃ）に示すように、矢印が含まれている。 The television 10 according to this modification generates a puzzle game as shown in (c) by superimposing a cursor and a black image on a partial image obtained by dividing the frame image shown in FIG. Further, the black image superimposed on the partial image includes an arrow as shown in FIGS. 7B and 7C.
　このとき、本変形例に係るテレビ１０のモザイク化処理部１２０、及び、当該モザイク化処理部１２０の備える各部は、例えば、次のように重畳モザイク化画像生成処理を実行することにより、図７（ｃ）に示すパズルゲームを生成する。 At this time, the mosaic processing unit 120 of the television 10 according to the present modification and each unit included in the mosaic processing unit 120 perform the superimposed mosaiced image generation process as follows, for example, as illustrated in FIG. The puzzle game shown in (c) is generated.
　〔重畳モザイク化画像生成処理〕
　モザイク化処理部１２０は、パズル表示指示を受け付けると、モザイク化画像生成処理を開始する。 [Superimposed mosaic image generation processing]
When receiving the puzzle display instruction, the mosaic processing unit 120 starts the mosaic image generation process.
　モザイク化処理部１２０は、パズル表示指示を取得すると、まず、配置参照用フレームとして、取得したパズル表示指示において指定されているパズルゲーム（図７（ｃ）に示すパズルゲーム）と関連付けられているパズル用フレームを、記憶部から読み出す。 When the mosaic processing unit 120 acquires the puzzle display instruction, first, it is associated with the puzzle game specified in the acquired puzzle display instruction (the puzzle game shown in FIG. 7C) as the arrangement reference frame. The puzzle frame is read from the storage unit.
　モザイク化処理部１２０は、パズル用フレームを読み出すと、部分画像の何れを、パズル用フレームの何れのブロックに配置するかを決定するための配置テーブルを生成する。このとき、配置テーブルには、黒画像を配置するブロック、及び、カーソルを配置するブロックも併せて示されていることが好ましい。 When the mosaic processing unit 120 reads out the puzzle frame, the mosaic processing unit 120 generates an arrangement table for determining which of the partial images is arranged in which block of the puzzle frame. At this time, it is preferable that the arrangement table also shows a block in which a black image is arranged and a block in which a cursor is arranged.
　次に、モザイク化処理部１２０の備える逆モザイク化部１２１は、部分画像に重畳（配置）するためのカーソルを示すカーソルデータを取得する。そして、逆モザイク化部１２１は、配置テーブルを参照し、取得したカーソルデータの示すカーソルをパズル用フレームの対応するブロックに配置（逆モザイク化処理）した逆モザイク化オブジェクトを生成する。このとき、逆モザイク化部１２１は、逆モザイク化オブジェクトと共に、矢印を含む黒画像を生成する。 Next, the inverse mosaicing unit 121 included in the mosaic processing unit 120 acquires cursor data indicating a cursor for superimposing (arranging) on the partial image. Then, the inverse mosaicing unit 121 refers to the arrangement table, and generates an inverse mosaiced object in which the cursor indicated by the acquired cursor data is arranged (inverse mosaicing processing) in the corresponding block of the puzzle frame. At this time, the inverse mosaicing unit 121 generates a black image including an arrow together with the inverse mosaiced object.
　重畳部１２２は、逆モザイク化オブジェクトが生成されると、グラフィックバッファ１０６に格納されているコマ画像（例えば、図７（ａ））を取得し、取得したコマ画像をパズル用フレームの有するブロックに配置可能なように複数の部分画像に分割する。 When the de-mosaic object is generated, the superimposing unit 122 acquires a frame image (for example, FIG. 7A) stored in the graphic buffer 106, and converts the acquired frame image into a block included in the puzzle frame. The image is divided into a plurality of partial images so that they can be arranged.
　コマ画像を部分画像に分割すると、重畳部１２２は、逆モザイク化オブジェクトを、部分画像に分割されたコマ画像に重畳する。このとき、逆モザイク化オブジェクトが重畳された部分画像は、例えば、図７（ｂ）に示すようになる。 When the frame image is divided into partial images, the superimposing unit 122 superimposes the de-mosaic object on the frame image divided into the partial images. At this time, the partial image on which the inverse mosaicked object is superimposed is as shown in FIG. 7B, for example.
　そして、モザイク化部１２３は、配置テーブルを参照し、逆モザイク化オブジェクトが重畳された部分画像をパズル用フレームの対応するブロックに配置（モザイク化処理）すると共に、矢印を含む黒画像を部分画像に重畳して配置した重畳モザイク化画像を生成する。このとき、重畳モザイク化画像は、例えば、図７（ｃ）に示すようになる。 Then, the mosaicing unit 123 refers to the arrangement table, arranges the partial image on which the inverse mosaicked object is superimposed on the corresponding block of the puzzle frame (mosaicing process), and converts the black image including the arrow into the partial image. A superimposed mosaic image is generated that is superimposed on the image. At this time, the superimposed mosaic image is, for example, as shown in FIG.
　本変形例に係るテレビ１０は、モザイク化処理部１２０において上述の処理を実行することにより、図７（ｃ）に示すような、黒画像の表示されたブロックの左右上下に隣接するブロックにカーソルが配置されたパズルゲームを生成する。 The television 10 according to the present modification performs the above-described processing in the mosaic processing unit 120, thereby moving the cursor to blocks adjacent to the left, right, top, and bottom of the block displaying the black image as illustrated in FIG. Generate a puzzle game in which is placed.
　なお、モザイク化処理部１２０は、上述のようにしてパズルゲームを生成した後は、グラフィックバッファに逐次格納されるコマ画像を逐次取得して上述の処理を繰り返し実行する。これにより、各ブロックに配置される部分画像が逐次更新されるため、パズルゲームを動画像により実現することができる。 In addition, after generating the puzzle game as described above, the mosaic processing unit 120 sequentially acquires the frame images sequentially stored in the graphic buffer and repeatedly executes the above-described processing. Thereby, since the partial image arrange | positioned at each block is updated sequentially, a puzzle game is realizable with a moving image.
　（オブジェクトの明滅）
　モザイク化処理部１２０は、さらに、パズルゲームにおいて表示されているカーソル、及び、矢印を明滅させてもよい。より具体的には、モザイク化処理部１２０は、当該モザイク化処理部１２０の備える逆モザイク化部１２１を、ＵＩ要素の表示態様を周期的に変化させる表示態様変更手段としても機能させることにより、カーソル、及び、矢印を明滅させる。 (Blink object)
The mosaic processing unit 120 may further blink the cursor and the arrow displayed in the puzzle game. More specifically, the mosaic processing unit 120 causes the inverse mosaicing unit 121 included in the mosaic processing unit 120 to function as a display mode changing unit that periodically changes the display mode of the UI element. Blinks the cursor and arrow.
　パズルゲームに表示されているカーソル及び矢印の明滅について、図８を参照して説明する。図８は、本変形例に係るパズルゲームに表示されているカーソル及び矢印の明滅の周期の一例を示すグラフである。図８（ａ）は、カーソルの明滅の周期の一例を示し、（ｂ）は、矢印の明滅の周期の一例を示している。 The blinking of the cursor and arrow displayed in the puzzle game will be described with reference to FIG. FIG. 8 is a graph showing an example of the blinking cycle of the cursor and the arrow displayed in the puzzle game according to this modification. FIG. 8A shows an example of the blinking cycle of the cursor, and FIG. 8B shows an example of the blinking cycle of the arrow.
　図８（ａ）及び（ｂ）に示すように、モザイク化処理部１２０の備える逆モザイク化部１２１は、カーソル及び矢印の明度を、所定の明度の範囲において周期的に明滅させるよう動作する。このとき、逆モザイク化部１２１は、カーソルの明滅の周期と、矢印の明滅の周期とが異なるように動作してもよい。 8A and 8B, the inverse mosaicing unit 121 included in the mosaic processing unit 120 operates to periodically blink the brightness of the cursor and the arrow within a predetermined brightness range. At this time, the inverse mosaicing unit 121 may operate such that the blinking cycle of the cursor is different from the blinking cycle of the arrow.
　逆モザイク化部１２１は、図８（ａ）に示すように、本変形例に係るパズルゲームのカーソルが、所定の明度の範囲の下限から上限まで段階的（例えば、１Ｖ周期毎）に明るくなり、明度が上限に達した後は、上限からか下限まで段階的に暗くなるよう動作する。また、逆モザイク化部１２１は、カーソルの明度が下限に達した後は、下限から上限まで再び段階的に明るくなるよう動作する。逆モザイク化部１２１は、上記の動作を繰り返すことにより、カーソルを周期的に明滅させる。 As shown in FIG. 8A, the inverse mosaicing unit 121 makes the cursor of the puzzle game according to the present modification brighter stepwise (for example, every 1V period) from the lower limit to the upper limit of the predetermined brightness range. After the brightness reaches the upper limit, it operates so as to gradually darken from the upper limit to the lower limit. In addition, after the brightness of the cursor reaches the lower limit, the inverse mosaicing unit 121 operates so that the brightness is gradually increased again from the lower limit to the upper limit. The inverse mosaicing unit 121 periodically blinks the cursor by repeating the above operation.
　逆モザイク化部１２１は、逆モザイク化オブジェクトに含まれるカーソルの明度を、直前に生成された逆モザイク化オブジェクトに含まれるカーソルに明度に対して変化させることによって、パズルゲームに表示されるカーソルの明度を段階的に変化させる。これによって、逆モザイク化部１２１は、上述のようにカーソルを周期的に明滅させることができる。 The inverse mosaicing unit 121 changes the brightness of the cursor included in the inverse mosaiced object to the cursor included in the inverse mosaiced object generated immediately before the brightness of the cursor displayed in the puzzle game. Change the brightness step by step. Thereby, the de-mosaic unit 121 can periodically blink the cursor as described above.
　一方、逆モザイク化部１２１は、図８（ｂ）に示すように、本変形例に係るパズルゲームの矢印が、所定の明度の範囲の下限から上限まで段階的に明るくなり、明度が上限に達した後は、上限から下限まで瞬時に暗くなるよう動作する。また、逆モザイク化部１２１は、矢印の明度が下限に達した後は、下限から上限まで再び段階的に明るくなるよう動作する。逆モザイク化部１２１は、上記の動作を繰り返すことにより、矢印を周期的に明滅させる。 On the other hand, as shown in FIG. 8B, the inverse mosaicing unit 121 gradually increases the brightness of the arrow of the puzzle game according to this modification from the lower limit to the upper limit of the predetermined brightness range. After reaching, it works to darken instantaneously from the upper limit to the lower limit. In addition, after the brightness of the arrow reaches the lower limit, the inverse mosaicing unit 121 operates so that the brightness gradually increases again from the lower limit to the upper limit. The inverse mosaicing unit 121 periodically blinks the arrow by repeating the above operation.
　逆モザイク化部１２１は、また、パズルゲームに表示されている黒画像と選択部分画像との配置位置の入れ替えが行われる場合（図８（ｂ）に示す「パネル移動発生」）、矢印の明度を、所定の明度の範囲の下限よりもさらに暗くする。これにより、黒画像と選択部分画像との配置位置の入れ替えが行われている間は、矢印を目立たなくすることができる。 The inverse mosaicing unit 121 also performs the brightness of the arrow when the arrangement position of the black image and the selected partial image displayed in the puzzle game is exchanged (“panel movement occurrence” shown in FIG. 8B). Is made darker than the lower limit of the predetermined brightness range. As a result, the arrows can be made inconspicuous while the arrangement positions of the black image and the selected partial image are changed.
　なお、本変形例では、逆モザイク化部１２１において、カーソル及び矢印の明度を段階的に変化させることにより周期的にカーソル及び矢印を明滅させる構成を例に挙げて説明したが、カーソル及び矢印を変化させる方法はこれに限定されるものではない。逆モザイク化部１２１は、例えば、カーソル及び矢印の色を周期的に変化させてもよいし、カーソル及び矢印の明度及び色を共に周期的に変化させてもよい。 In addition, in this modification, in the demosaicization unit 121, the configuration in which the cursor and the arrow are periodically blinked by changing the brightness of the cursor and the arrow in steps has been described as an example. The method of changing is not limited to this. For example, the inverse mosaicing unit 121 may periodically change the color of the cursor and the arrow, or may periodically change both the brightness and the color of the cursor and the arrow.
　＜変形例２＞
　本実施形態に係るテレビ１０において表示可能なパズルゲームは、黒画像と選択部分画像との配置ブロックを入れ替えるパズルゲームに限定されるものではない。本実施形態の他の変形例について、図９を参照して説明する。図９は、本変形例に係るパズルゲームの一例を模式的示す図である。図９（ａ）は、本変形例に係るパズルゲームの一例を模式的に示し、（ｂ）及び（ｃ）は、カーソルの明滅の周期の一例を示している。 <Modification 2>
The puzzle game that can be displayed on the television 10 according to the present embodiment is not limited to the puzzle game in which the arrangement blocks of the black image and the selected partial image are exchanged. Another modification of the present embodiment will be described with reference to FIG. FIG. 9 is a diagram schematically illustrating an example of a puzzle game according to the present modification. FIG. 9A schematically shows an example of a puzzle game according to this modification, and FIGS. 9B and 9C show an example of the blinking cycle of the cursor.
　図９（ａ）に示すパズルゲームは、４行４列の合計１６枚に分割された部分画像のうち、カーソルαによって選択されている選択部分画像と、カーソルβによって選択されている選択部分画像との配置位置を入れ替える操作を繰り返すことにより、モザイク化画像生成処理の施される前の画像に戻すパズルゲームの一例である。 The puzzle game shown in FIG. 9A is a selected partial image selected by the cursor α and a selected partial image selected by the cursor β among the partial images divided into a total of 16 pieces of 4 rows and 4 columns. It is an example of the puzzle game which returns to the image before performing the mosaic image generation process by repeating the operation of changing the arrangement position.
　（オブジェクトの明滅）
　モザイク化処理部１２０は、図９（ａ）に示すパズルゲームにおいて、当該パズルゲームに表示されているカーソルα、及び、カーソルβを、それぞれ明滅させる。図９（ａ）に示すパズルゲームに表示されているカーソルα及びカーソルβの明滅について、図９（ｂ）及び（ｃ）を参照して説明する。 (Blink object)
In the puzzle game shown in FIG. 9A, the mosaic processing unit 120 blinks the cursor α and the cursor β displayed in the puzzle game. The blinking of the cursor α and the cursor β displayed in the puzzle game shown in FIG. 9A will be described with reference to FIGS. 9B and 9C.
　図８（ｂ）及び（ｃ）に示すように、モザイク化処理部１２０の備える逆モザイク化部１２１は、カーソルα及びカーソルβの明度を、所定の明度の範囲において周期的に明滅させるよう動作する。このとき、逆モザイク化部１２１は、カーソルαの明滅の周期と、カーソルβの明滅の周期とが異なるように動作してもよい。カーソルα及びカーソルβの明滅の周期を異ならせることにより、カーソルα及びカーソルβにフォーカスされている部分画像を各々目立たせることができる。 As shown in FIGS. 8B and 8C, the inverse mosaicing unit 121 included in the mosaic processing unit 120 operates so as to periodically blink the brightness of the cursor α and the cursor β within a predetermined brightness range. To do. At this time, the inverse mosaicing unit 121 may operate so that the blinking cycle of the cursor α is different from the blinking cycle of the cursor β. By making the blinking cycles of the cursor α and the cursor β different, it is possible to make the partial images focused on the cursor α and the cursor β stand out.
　また、逆モザイク化部１２１は、カーソルα及びカーソルβの明度を、周期が同じであって且つ位相が反転するように明滅させてもよい。具体的には、逆モザイク化部１２１は、カーソルαが明るいときにはカーソルβが暗く、カーソルαが暗いときにカーソルβが明るくなるように、カーソルα及びカーソルβを明滅させる。これにより、カーソルα及びカーソルβにフォーカスされている部分画像を各々目立たせることができる。 Further, the inverse mosaicing unit 121 may blink the brightness of the cursor α and the cursor β so that the period is the same and the phase is inverted. Specifically, the inverse mosaicing unit 121 blinks the cursor α and the cursor β so that the cursor β is dark when the cursor α is bright and the cursor β is bright when the cursor α is dark. Thereby, the partial images focused on the cursor α and the cursor β can be made conspicuous.
　なお、逆モザイク化部１２１におけるカーソルα及びカーソルβの明滅の動作は、変形例１に係る逆モザイク化部１２１の動作と同様であるため、ここではその説明は省略する。 Note that the blinking operation of the cursor α and the cursor β in the inverse mosaicing unit 121 is the same as the operation of the inverse mosaicing unit 121 according to the first modification, and thus description thereof is omitted here.
　＜変形例３＞
　本実施形態に係るテレビ１０において表示可能なパズルゲームは、黒画像と選択部分画像との配置ブロックを入れ替えるパズルゲームに限定されるものではない。本実施形態のさらに他の変形例について、図１０を参照して説明する。図１０は、本変形例に係るモザイク化画像生成処理の流れを模式的に示す図である。図１０（ａ）は重畳モザイク化画像生成処理が施される前のコマ画像の一例を示し、（ｂ）は逆モザイク化されたカーソル及び矢印の一例を示し、（ｃ）は重畳モザイク化画像生成処理の施された重畳モザイク化画像の一例を示す。 <Modification 3>
The puzzle game that can be displayed on the television 10 according to the present embodiment is not limited to the puzzle game in which the arrangement blocks of the black image and the selected partial image are exchanged. Still another modification of the present embodiment will be described with reference to FIG. FIG. 10 is a diagram schematically illustrating the flow of the mosaiced image generation process according to this modification. FIG. 10A shows an example of a frame image before the superimposed mosaiced image generation process is performed, FIG. 10B shows an example of a reverse mosaiced cursor and arrow, and FIG. 10C shows a superimposed mosaiced image. An example of a superimposed mosaic image that has been subjected to generation processing is shown.
　なお、図１０（ｃ）に示すパズルゲームでは、ユーザは、重畳モザイク化画像処理の施された画像において、或る１つのブロックに配置されている部分画像をカーソルにより選択すると共に、選択した部分画像を移動させる方向を矢印を選択することにより選択する。これにより、選択された矢印の示す方向に沿った列又は行に属する全ての部分画像が、各部分画像の配置されているブロックに隣接するブロックであって選択された矢印の示す方向に隣接するブロックに再配置される。 In the puzzle game shown in FIG. 10C, the user selects a partial image arranged in a certain block with the cursor in the image subjected to the superimposed mosaic image processing, and the selected portion. Select the direction to move the image by selecting the arrow. Accordingly, all partial images belonging to the column or row along the direction indicated by the selected arrow are adjacent to the block in which each partial image is arranged and are adjacent to the direction indicated by the selected arrow. Relocated to block.
　ここで、パズル用フレームの縁に属するブロック（縁ブロック）であってユーザにより選択された矢印の示す方向に沿った縁ブロックのうち、該選択された矢印の示す方向側の縁ブロックには、該選択された矢印の示す方向に隣接するブロックが存在しない。この場合には、ユーザにより選択された矢印の示す方向側の縁ブロックと反対側（他方）の縁ブロックを該選択された矢印の示す方向に隣接するブロックとみなせばよい。 Here, among the edge blocks along the direction indicated by the arrow selected by the user that belong to the edge of the puzzle frame (edge block), the edge block on the direction side indicated by the selected arrow includes: There is no adjacent block in the direction indicated by the selected arrow. In this case, the edge block on the side opposite to the edge block indicated by the arrow selected by the user (the other side) may be regarded as a block adjacent in the direction indicated by the selected arrow.
　また、図１０（ｃ）に示すように、カーソルにより選択された部分画像が移動可能な方向に属さない部分画像は、カーソルにより選択された部分画像が移動可能な方向に属する部分画像よりも、暗く表示される。例えば、モザイク化処理部１２０の備える逆モザイク化部１２１が透過率の低い重畳画像を生成し、重畳部１２２が当該重畳画像を対応する部分画像に重畳することにより、重畳画像の重畳された部分画像を暗く表示することができる。 Also, as shown in FIG. 10C, the partial image that does not belong to the direction in which the partial image selected by the cursor can move is more than the partial image that belongs to the direction in which the partial image selected by the cursor can move. It appears dark. For example, the inverse mosaicing unit 121 included in the mosaicing processing unit 120 generates a superimposed image with low transmittance, and the superimposing unit 122 superimposes the superimposed image on the corresponding partial image, thereby superimposing the superimposed image. The image can be displayed darkly.
　〔重畳モザイク化画像生成処理〕
　本変形例に係るテレビ１０のモザイク化処理部１２０、及び、当該モザイク化処理部１２０の備える各部は、例えば、次のように重畳モザイク化画像生成処理を実行することにより、図１０（ｃ）に示すパズルゲームを生成する。 [Superimposed mosaic image generation processing]
The mosaic processing unit 120 of the television 10 according to this modification and each unit included in the mosaic processing unit 120 execute the superimposed mosaiced image generation process as follows, for example, as illustrated in FIG. A puzzle game shown in FIG.
　モザイク化処理部１２０は、パズル表示指示を受け付けると、モザイク化画像生成処理を開始する。 When the mosaic processing unit 120 receives a puzzle display instruction, the mosaic processing unit 120 starts a mosaic image generation process.
　モザイク化処理部１２０は、パズル表示指示を取得すると、まず、配置参照用フレームとして、取得したパズル表示指示において指定されているパズルゲーム（図１０（ｃ）に示すパズルゲーム）と関連付けられているパズル用フレームを、記憶部から読み出す。 When the mosaic processing unit 120 acquires the puzzle display instruction, first, it is associated with the puzzle game specified in the acquired puzzle display instruction (puzzle game shown in FIG. 10C) as an arrangement reference frame. The puzzle frame is read from the storage unit.
　モザイク化処理部１２０は、パズル用フレームを読み出すと、配置テーブルを生成する。このとき、配置テーブルには、重畳画像を配置するブロック、及び、カーソルを配置するブロックも併せて示されていることが好ましい。 When the mosaic processing unit 120 reads out the puzzle frame, it generates an arrangement table. At this time, it is preferable that the arrangement table also shows a block in which the superimposed image is arranged and a block in which the cursor is arranged.
　次に、逆モザイク化部１２１は、部分画像に重畳（配置）するためのカーソルを示すカーソルデータ、及び、重畳画像を示す重畳画像データを取得する。そして、逆モザイク化部１２１は、配置テーブルを参照し、取得したカーソルデータの示すカーソル、及び、重畳画像データの示す重畳画像をパズル用フレームの対応するブロックに配置（逆モザイク化）した逆モザイク化オブジェクトを生成する。 Next, the inverse mosaicing unit 121 acquires cursor data indicating a cursor to be superimposed (arranged) on the partial image and superimposed image data indicating the superimposed image. Then, the inverse mosaicing unit 121 refers to the placement table, and places the cursor indicated by the acquired cursor data and the superimposed image indicated by the superimposed image data on the corresponding block of the puzzle frame (inverse mosaicing). Generate a generalized object.
　重畳部１２２は、逆モザイク化オブジェクトが生成されると、グラフィックバッファ１０６に格納されているコマ画像（例えば、図１０（ａ））を取得し、取得したコマ画像をパズル用フレームの有するブロックに配置可能なように複数の部分画像に分割する。 When the inverse-mosaic object is generated, the superimposing unit 122 acquires a frame image (for example, FIG. 10A) stored in the graphic buffer 106, and converts the acquired frame image into a block included in the puzzle frame. The image is divided into a plurality of partial images so that they can be arranged.
　コマ画像を部分画像に分割すると、重畳部１２２は、逆モザイク化オブジェクトを、部分画像に分割されたコマ画像に重畳する。このとき、逆モザイク化オブジェクトが重畳された部分画像は、例えば、図１０（ｂ）に示すようになる。 When the frame image is divided into partial images, the superimposing unit 122 superimposes the de-mosaic object on the frame image divided into the partial images. At this time, the partial image on which the inverse mosaicked object is superimposed is, for example, as shown in FIG.
　そして、モザイク化部１２３は、配置テーブルを参照し、逆モザイク化オブジェクトが重畳された部分画像をパズル用フレームの対応するブロックに配置（モザイク化）した重畳モザイク化画像を生成する。このとき、重畳モザイク化画像は、例えば、図１０（ｃ）に示すようになる。 Then, the mosaic unit 123 refers to the arrangement table, and generates a superimposed mosaic image in which the partial image on which the inverse mosaic object is superimposed is arranged (mosaiced) in the corresponding block of the puzzle frame. At this time, the superimposed mosaic image is, for example, as shown in FIG.
　なお、モザイク化処理部１２０は、グラフィックバッファ１０６に逐次格納されるコマ画像を逐次取得して上述の処理を繰り返し実行することにより、各ブロックに配置される部分画像が逐次更新されるため、パズルゲームを動画像により実現することができる。 Note that the mosaic processing unit 120 sequentially acquires the frame images sequentially stored in the graphic buffer 106 and repeatedly executes the above-described processing, whereby the partial images arranged in each block are sequentially updated. The game can be realized by moving images.
　（オブジェクトの移動）
　モザイク化処理部１２０は、さらに、パズルゲームにおいて表示されている矢印の表示位置を移動させてもよい。より具体的には、モザイク化処理部１２０は、当該モザイク化処理部１２０の備える逆モザイク化部１２１を、ＵＩ要素の表示態様を周期的に変化させる表示態様変更手段としても機能させることにより、矢印の表示位置を移動させればよい。 (Move object)
The mosaic processing unit 120 may further move the display position of the arrow displayed in the puzzle game. More specifically, the mosaic processing unit 120 causes the inverse mosaicing unit 121 included in the mosaic processing unit 120 to function as a display mode changing unit that periodically changes the display mode of the UI element. The display position of the arrow may be moved.
　パズルゲームに表示されている矢印の移動について、図１１及び図１２を参照して説明する。図１１は、本変形例に係るパズルゲームに表示される矢印の移動の一例を模式的に示す図である。図１１（ａ）は、矢印の移動の一例を模式的に示し、（ｂ）は、矢印の移動の周期の一例を示している。 The movement of the arrow displayed in the puzzle game will be described with reference to FIGS. FIG. 11 is a diagram schematically illustrating an example of movement of an arrow displayed in the puzzle game according to the present modification. FIG. 11A schematically shows an example of arrow movement, and FIG. 11B shows an example of the period of arrow movement.
　また、図１２は、本変形例に係るパズルゲームにリモコン２０のキーガイダンスが表示されている場合の矢印の移動を模式的に示す図である。図１２（ａ）は、キーガイダンスに矢印が隠れている場合の一例を示し、（ｂ）は、キーガイダンスに矢印が隠れていない場合の一例を示している。 FIG. 12 is a diagram schematically showing the movement of the arrow when the key guidance of the remote controller 20 is displayed in the puzzle game according to this modification. FIG. 12A shows an example when the arrow is hidden in the key guidance, and FIG. 12B shows an example when the arrow is not hidden in the key guidance.
　逆モザイク化部１２１は、図１１（ａ）及び（ｂ）に示すように、カーソルにより選択された部分画像内に表示される矢印の表示位置を、部分画像内において周期的に移動させるよう動作する。 As shown in FIGS. 11A and 11B, the de-mosaic unit 121 operates to periodically move the display position of the arrow displayed in the partial image selected by the cursor in the partial image. To do.
　具体的には、逆モザイク化部１２１は、図１１（ｂ）に示すように、本変形例に係るパズルゲームの矢印の表示位置が、部分画像内の内側から外側に向けて段階的（例えば、１Ｖ周期毎）に移動し、矢印の先端の表示位置が部分画像の縁に達した後は、外側からか内側まで瞬時に移動するよう動作する。そして、逆モザイク化部１２１は、矢印の表示位置が外側からか内側まで移動させた後は、矢印の表示位置が内側から外側まで再び段階的に移動するよう動作する。 Specifically, as shown in FIG. 11B, the inverse mosaicing unit 121 gradually changes the display position of the arrow of the puzzle game according to the present modification from the inside to the outside in the partial image (for example, 1 cycle), and after the display position of the tip of the arrow reaches the edge of the partial image, it operates to move instantaneously from the outside to the inside. Then, after the display position of the arrow is moved from the outside to the inside, the inverse mosaicing unit 121 operates such that the display position of the arrow is gradually moved again from the inside to the outside.
　さらに、逆モザイク化部１２１は、カーソルにより選択されている部分画像が、選択された矢印に沿った方向に移動する場合（図１１（ｂ）に示す「パネル移動発生」）、矢印の表示位置を、矢印の先端が部分画像の縁に位置する表示位置で固定してもよい。これにより、部分画像が移動している間、矢印を目立たなくすることができる。 Further, when the partial image selected by the cursor moves in the direction along the selected arrow (“panel movement occurrence” shown in FIG. 11B), the inverse mosaicing unit 121 displays the arrow display position. May be fixed at the display position where the tip of the arrow is located at the edge of the partial image. Thereby, the arrow can be made inconspicuous while the partial image is moving.
　また、カーソルにより選択されている部分画像内で矢印を移動させることにより、例えば、図１２（ａ）に示すように表示画面の下部に表示したリモコン２０のキーガイダンスにより矢印が隠れてしまう場合などであっても、（ｂ）に示すようにキーガイダンスにより矢印の全体を表示することができる。 Further, by moving the arrow in the partial image selected by the cursor, for example, the arrow is hidden by the key guidance of the remote controller 20 displayed at the bottom of the display screen as shown in FIG. Even so, the entire arrow can be displayed by key guidance as shown in FIG.
　これにより、パズルゲームに例えばＯＳＤなど当該パズルゲーム以外の表示が重畳された場合であっても、矢印などのオブジェクトの視認性の低下を抑制することができる。 Thereby, even when a display other than the puzzle game such as OSD is superimposed on the puzzle game, for example, it is possible to suppress a decrease in visibility of an object such as an arrow.
