BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a display system 100 according to the first embodiment. A display system 100 includes a display device 1 and a video signal output device 2 . The video signal output device 2 is connected to the display device 1 by, for example, an electric line, and outputs a video signal.
　表示装置１は、映像信号制御部１０と、ＬＥＤモジュール部２０とを備える。映像信号制御部１０と、ＬＥＤモジュール部２０とは、例えば、電気回線により接続されている。ＬＥＤモジュール部２０は、測定部２２、送受信部２３、ＬＥＤドライバ部２４、複数のＬＥＤ素子２１－１，２１－２，…、図２に示す複数の棒状フレーム３０－１，３０－２，…、及び伸縮構造体４０を備える。 The display device 1 includes a video signal control section 10 and an LED module section 20 . The video signal control section 10 and the LED module section 20 are connected by, for example, an electric line. The LED module section 20 includes a measuring section 22, a transmitting/receiving section 23, an LED driver section 24, a plurality of LED elements 21-1, 21-2, . , and a telescopic structure 40 .
　複数のＬＥＤ素子２１－１～２１－Ｎの数である「Ｎ」は、予め定められる２以上の整数値であり、図２では、Ｎ＝７０の例を示している。以下、ＬＥＤ素子２１－１～２１－Ｎの中のいずれか１つの任意のものを示す場合、符号に枝番号を付さずに、ＬＥＤ素子２１という。複数の棒状フレーム３０－１，３０－２，…の数も予め定められる２以上の整数値であり、図２では、１０個の棒状フレーム３０－１～３０－１０を備える例を示している。棒状フレーム３０－１～３０－１０の各々は、形状が棒状である棒状部材であり、予め定められる数のＬＥＤ素子２１が、均等な間隔で取り付けられる。図２では、棒状フレーム３０－１～３０－１０の各々に、７個ずつＬＥＤ素子２１が取り付けられている例を示している。 "N", which is the number of the plurality of LED elements 21-1 to 21-N, is a predetermined integer value of 2 or more, and FIG. 2 shows an example of N=70. Hereinafter, any one of the LED elements 21-1 to 21-N will be referred to as the LED element 21 without any additional number. The number of the plurality of rod-shaped frames 30-1, 30-2, . . . is also a predetermined integer value of 2 or more, and FIG. . Each of the rod-shaped frames 30-1 to 30-10 is a rod-shaped member having a rod-like shape, and a predetermined number of LED elements 21 are mounted at regular intervals. FIG. 2 shows an example in which seven LED elements 21 are attached to each of the rod-shaped frames 30-1 to 30-10.
　伸縮構造体４０は、発光体が第１方向と当該第１方向とは直交する方向である第２方向とに沿って並ぶように支持部材を支持し、前記第１方向において隣接する発光体のそれぞれの間隔を伸縮させる。
　例えば伸縮構造体４０は、複数の棒状フレーム３０－１～３０－１０が平行に並び、かつ棒状フレーム３０－１～３０－１０の長手方向に対して直交する方向に向かって直線状にＬＥＤ素子２１が並ぶように、複数の棒状フレーム３０－１～３０－１０を支持している。ここで、棒状フレーム３０－１～３０－１０の長手方向に対して直交する方向に向かって直線状にＬＥＤ素子２１が並ぶ状態とは、例えば、左端の列のＬＥＤ素子２１－１，２１－８，２１－１５，２１－２２，２１－２９，２１－３６，２１－４３，２１－５０，２１－５７，２１－６４が直線状に並ぶ状態のことである。棒状フレーム３０－１～３０－１０の各々には、ＬＥＤ素子２１が、７個ずつ均等な間隔で取り付けられているため、他の列のＬＥＤ素子２１についても、同様に、棒状フレーム３０－１～３０－１０の長手方向に対する直交方向に向かって直線状に並ぶ状態になる。 The stretchable structure 40 supports the support member so that the light emitters are aligned along a first direction and a second direction perpendicular to the first direction, and the light emitters adjacent to each other in the first direction are aligned. Stretch each interval.
For example, the elastic structure 40 includes a plurality of rod-shaped frames 30-1 to 30-10 arranged in parallel, and the LED elements arranged linearly in a direction orthogonal to the longitudinal direction of the rod-shaped frames 30-1 to 30-10. A plurality of rod-shaped frames 30-1 to 30-10 are supported so that 21 are lined up. Here, the state in which the LED elements 21 are arranged linearly in a direction perpendicular to the longitudinal direction of the rod-shaped frames 30-1 to 30-10 means, for example, the LED elements 21-1 and 21- in the leftmost column. 8, 21-15, 21-22, 21-29, 21-36, 21-43, 21-50, 21-57, and 21-64 are arranged in a straight line. Since seven LED elements 21 are attached to each of the rod-shaped frames 30-1 to 30-10 at equal intervals, the LED elements 21 of the other rows are similarly attached to the rod-shaped frame 30-1. ∼30-10 in a straight line in the direction orthogonal to the longitudinal direction.
　伸縮構造体４０は、例えば、パンタグラフ構造が縦方向に多段に重ねられた伸縮構造を備えており、最上段の棒状フレーム３０－１を固定している状態で、最下段の棒状フレーム３０－１０を上下に動かすと、棒状フレーム３０－１～３０－１０の各々の間隔が伸縮可能、すなわち近接したり、離間したりするようになっている。より詳細には、伸縮構造体４０は棒状フレーム３０－１～３０－１０の各々の間隔が、均等、または、略均等である状態を維持しつつ、棒状フレーム３０－１～３０－１０の各々の間の距離を伸縮させるように構造が変化する。 The telescopic structure 40 has, for example, a telescopic structure in which pantograph structures are stacked in multiple stages in the vertical direction. is moved up and down, the distance between each of the rod-shaped frames 30-1 to 30-10 can be expanded and contracted, that is, they can be moved closer to each other or separated from each other. More specifically, the telescopic structure 40 maintains a state in which the intervals between the rod-shaped frames 30-1 to 30-10 are equal or substantially equal, and each of the rod-shaped frames 30-1 to 30-10 The structure changes to stretch or shrink the distance between
　図３は、図２の正面図で示されるＬＥＤモジュール部２０を左右いずれかの側面からみたＬＥＤモジュール部２０の側面図である。最上段の棒状フレーム３０－１に延長フレーム５１が取り付けられており、最下段の棒状フレーム３０－１０に延長フレーム５２が取り付けられている。測定部２２は、例えば、距離センサであり、延長フレーム５１に取り付けられている。測定部２２は、延長フレーム５２の方向、すなわち、棒状フレーム３０－１～３０－１０の長手方向の垂直方向に向かってレーザ光を照射し、延長フレーム５２が反射するレーザ光を受光することにより、レーザ光の往復時間から、延長フレーム５１と、延長フレーム５２との間の距離Ｄを算出する。なお、測定部２２の厚みは、測定部２２が測定した距離Ｄが、延長フレーム５１と、延長フレーム５２との間の距離を示すとみなすことができるほどの微小な厚みであるものとする。 FIG. 3 is a side view of the LED module section 20 as seen from either the left or right side of the LED module section 20 shown in the front view of FIG. An extension frame 51 is attached to the uppermost rod-shaped frame 30-1, and an extension frame 52 is attached to the lowermost rod-shaped frame 30-10. The measurement unit 22 is, for example, a distance sensor and attached to the extension frame 51 . The measurement unit 22 irradiates a laser beam in the direction of the extension frame 52, that is, in the direction perpendicular to the longitudinal direction of the rod-shaped frames 30-1 to 30-10, and receives the laser beam reflected by the extension frame 52. , the distance D between the extended frame 51 and the extended frame 52 is calculated from the round trip time of the laser light. The thickness of the measuring part 22 is so small that the distance D measured by the measuring part 22 can be regarded as indicating the distance between the extension frames 51 and 52 .
　ＬＥＤドライバ部２４は、複数のＬＥＤ素子２１－１，２１－２，…のうちＬＥＤ制御信号において指定されているＬＥＤ素子２１－１，２１－２，…を点灯させる。ＬＥＤ制御信号において指定されていないＬＥＤ素子２１－１，２１－２，…は、消灯する。送受信部２３は、例えば、制御基板であり、測定部２２が算出した距離Ｄを示すデータを、電気回線を通じて映像信号制御部１０に送信し、映像信号制御部１０から電気回線を通じて受信するＬＥＤ制御信号をＬＥＤドライバ部２４に出力する。 The LED driver unit 24 lights the LED elements 21-1, 21-2, . The LED elements 21-1, 21-2, . . . that are not designated by the LED control signal are extinguished. The transmitting/receiving unit 23 is, for example, a control board, transmits data indicating the distance D calculated by the measuring unit 22 to the video signal control unit 10 through an electric line, and receives data from the video signal control unit 10 through an electric line. A signal is output to the LED driver section 24 .
　このようなＬＥＤモジュール部２０を用いることで、例えば、図４に示すように、窓７０の大きさに合わせて、ＬＥＤモジュール部２０の伸縮構造体４０を伸縮させることで、窓７０の上下の窓枠一杯まで、縦方向に均等、または略均等な間隔で複数のＬＥＤ素子２１－１，２１－２，…を配置して表示画面のサイズを大きくすることが可能になる。ただし、この場合、複数のＬＥＤ素子２１－１，２１－２，…が点灯することにより形成される像は、表示画面のサイズに応じた像ではない。そのため、表示画面のサイズに応じた像が形成されるように映像信号出力装置２が出力する映像信号をスケーリング、すなわち、拡大、または、縮小させ、スケーリングした映像信号に基づいて、複数のＬＥＤ素子２１－１，２１－２，…を点灯させる制御が必要となる。当該制御を行うのが映像信号制御部１０である。 By using such an LED module section 20, for example, as shown in FIG. By arranging a plurality of LED elements 21-1, 21-2, . However, in this case, the image formed by lighting the plurality of LED elements 21-1, 21-2, . . . does not correspond to the size of the display screen. Therefore, the video signal output by the video signal output device 2 is scaled, that is, enlarged or reduced, so that an image corresponding to the size of the display screen is formed, and based on the scaled video signal, a plurality of LED elements are displayed. 21-1, 21-2, . . . need to be controlled to light up. The video signal control unit 10 performs the control.
　映像信号制御部１０は、ＬＥＤコントローラ部１１と、ＬＥＤコントローラ設定部１２とを備える。ＬＥＤコントローラ設定部１２は、測定データ受信部１３、モジュールサイズ算出部１４、及びデータ出力部１５を備える。測定データ受信部１３は、測定部２２が算出した距離Ｄを示すデータを受信する。 The video signal control section 10 includes an LED controller section 11 and an LED controller setting section 12 . The LED controller setting section 12 includes a measurement data receiving section 13 , a module size calculating section 14 and a data output section 15 . The measurement data reception unit 13 receives data indicating the distance D calculated by the measurement unit 22 .
　モジュールサイズ算出部１４は、測定データ受信部１３が受信する距離Ｄを示すデータに基づいて、モジュールサイズ、すなわち、ＬＥＤモジュール部２０の複数のＬＥＤ素子２１－１，２１－２，…によって形成される表示画面のサイズを算出する。図３に示すように、測定部２２は、延長フレーム５１に取り付けられており、延長フレーム５１は、棒状フレーム３０－１に取り付けられている。また、測定部２２からのレーザ光を反射する延長フレーム５２は、棒状フレーム３０－１０に取り付けられている。そのため、測定部２２が測定する距離Ｄは、最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の正確な距離ではない。 The module size calculator 14 determines the module size, that is, the size of the LED elements 21-1, 21-2, . Calculate the size of the display screen to be used. As shown in FIG. 3, the measuring section 22 is attached to an extension frame 51, and the extension frame 51 is attached to a bar frame 30-1. An extension frame 52 that reflects the laser beam from the measuring section 22 is attached to the rod-shaped frame 30-10. Therefore, the distance D measured by the measuring unit 22 is the distance between the uppermost LED element 21-1 and the lowermost LED element 21-64 located on the straight line in the vertical direction when viewed from the LED element 21-1. Not exact distance.
　モジュールサイズ算出部１４は、予め定められている延長フレーム５１，５２と、棒状フレーム３０－１，３０－１０の各々に取り付けられているＬＥＤ素子２１との位置関係に基づいて、測定部２２が測定した距離Ｄから最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の距離を算出する。 The module size calculation unit 14 determines the position of the measurement unit 22 based on the predetermined positional relationship between the extension frames 51 and 52 and the LED elements 21 attached to the rod-shaped frames 30-1 and 30-10. From the measured distance D, the distance between the uppermost LED element 21-1 and the lowermost LED element 21-64 located on the vertical straight line from the LED element 21-1 is calculated.
　モジュールサイズ算出部１４は、内部の記憶領域に横方向のＬＥＤ素子２１の数と、縦方向のＬＥＤ素子２１の数とを予め記憶させている。モジュールサイズ算出部１４は、算出した最上段のＬＥＤ素子２１－１から最下段のＬＥＤ素子２１－６４までの距離を、内部の記憶領域が記憶する縦方向のＬＥＤ素子２１の数から「１」減算した値で除算して縦方向のＬＥＤ素子２１のピッチ長を算出する。なお、横方向のＬＥＤ素子２１のピッチ長は、固定値である。そのため、モジュールサイズ算出部１４は、内部の記憶領域に予め横方向のＬＥＤ素子２１のピッチ長を記憶させておく。 The module size calculator 14 stores in advance the number of LED elements 21 in the horizontal direction and the number of LED elements 21 in the vertical direction in an internal storage area. The module size calculator 14 determines the calculated distance from the uppermost LED element 21-1 to the lowermost LED element 21-64 as "1" from the number of vertical LED elements 21 stored in the internal storage area. The vertical pitch length of the LED elements 21 is calculated by dividing by the subtracted value. The pitch length of the LED elements 21 in the horizontal direction is a fixed value. Therefore, the module size calculator 14 stores in advance the pitch length of the LED elements 21 in the horizontal direction in an internal storage area.
　ここで、モジュールサイズ、すなわち表示画面のサイズの定義について説明する。１つのＬＥＤ素子２１によって形成される表示画面の大きさを、当該ＬＥＤ素子２１の位置を中心とした矩形領域であって当該矩形領域の横方向の長さを横方向のＬＥＤ素子２１のピッチ長とし、当該矩形領域の縦方向の長さを縦方向のＬＥＤ素子２１のピッチ長とする矩形領域の大きさとして定義する。複数の棒状フレーム３０－１～３０－１０の各々の間隔が均等であるとした場合に、ＬＥＤ素子２１の各々の矩形領域を、各々のＬＥＤ素子２１の位置に合わせて連結した領域が、表示画面の領域になる。そのため、表示画面の縦方向の長さは、縦方向のＬＥＤ素子２１が均等な距離で並んでいる場合、矩形領域の縦方向の長さ、すなわち縦方向のＬＥＤ素子２１のピッチ長に縦方向のＬＥＤ素子２１の数を乗算した値になる。また、表示画面の横方向の長さは、矩形領域の横方向の長さ、すなわち横方向のＬＥＤ素子２１のピッチ長に横方向のＬＥＤ素子２１の数を乗算した値になる。乗算により算出した表示画面の縦方向の長さと、横方向の長さとが、表示画面のサイズ、すなわちモジュールサイズを示すデータになる。 Here, we will explain the definition of the module size, that is, the size of the display screen. The size of the display screen formed by one LED element 21 is a rectangular area centered on the position of the LED element 21, and the horizontal length of the rectangular area is the pitch length of the LED element 21 in the horizontal direction. , and defined as the size of the rectangular area with the vertical length of the rectangular area being the pitch length of the LED elements 21 in the vertical direction. Assuming that the intervals between each of the plurality of rod-shaped frames 30-1 to 30-10 are uniform, the area where each rectangular area of the LED element 21 is aligned with the position of each LED element 21 and connected is displayed. screen area. Therefore, the length of the display screen in the vertical direction is the length of the rectangular area in the vertical direction, that is, the pitch length of the LED elements 21 in the vertical direction, when the LED elements 21 in the vertical direction are arranged at equal distances. is multiplied by the number of LED elements 21. The horizontal length of the display screen is the horizontal length of the rectangular area, that is, the value obtained by multiplying the pitch length of the LED elements 21 in the horizontal direction by the number of the LED elements 21 in the horizontal direction. The length in the vertical direction and the length in the horizontal direction of the display screen calculated by multiplication become data indicating the size of the display screen, that is, the module size.
　上記した定義にしたがって、モジュールサイズ算出部１４は、算出した縦方向のＬＥＤ素子２１のピッチ長と、内部の記憶領域が記憶する縦方向のＬＥＤ素子２１の数とを乗算して、表示画面の縦方向の長さを算出する。また、モジュールサイズ算出部１４は、内部の記憶領域が記憶する横方向のＬＥＤ素子２１のピッチ長と、内部の記憶領域が記憶する横方向のＬＥＤ素子２１の数とを乗算して、表示画面の横方向の長さを算出する。 According to the above definition, the module size calculation unit 14 multiplies the calculated pitch length of the LED elements 21 in the vertical direction by the number of the LED elements 21 in the vertical direction stored in the internal storage area to obtain the display screen size. Calculate the vertical length. Further, the module size calculator 14 multiplies the pitch length of the horizontal LED elements 21 stored in the internal storage area by the number of horizontal LED elements 21 stored in the internal storage area, and calculates the display screen size. Calculate the horizontal length of
　データ出力部１５は、モジュールサイズ算出部１４が算出するモジュールサイズを示すデータをＬＥＤコントローラ部１１に出力する。ＬＥＤコントローラ部１１は、内部の記憶領域にＬＥＤモジュール部２０の縦方向のＬＥＤ素子２１の数と、横方向のＬＥＤ素子２１の数とを予め記憶させている。ＬＥＤコントローラ部１１は、データ出力部１５が出力するモジュールサイズと、内部の記憶領域が記憶するＬＥＤモジュール部２０の縦方向のＬＥＤ素子２１の数と、横方向のＬＥＤ素子２１の数とに基づいて、映像信号出力装置２が出力する映像信号をスケーリングする。ＬＥＤコントローラ部１１は、スケーリングした映像信号に基づいて、点灯させるＬＥＤ素子２１－１～２１－Ｎを指定するＬＥＤ制御信号を生成する。ＬＥＤコントローラ部１１は、生成したＬＥＤ制御信号をＬＥＤモジュール部２０に送信する。 The data output unit 15 outputs data indicating the module size calculated by the module size calculation unit 14 to the LED controller unit 11 . The LED controller section 11 stores in advance the number of LED elements 21 in the vertical direction and the number of LED elements 21 in the horizontal direction of the LED module section 20 in an internal storage area. Based on the module size output by the data output unit 15, the number of LED elements 21 in the vertical direction, and the number of LED elements 21 in the horizontal direction of the LED module unit 20 stored in the internal storage area, the LED controller unit 11 to scale the video signal output by the video signal output device 2 . Based on the scaled video signal, the LED controller unit 11 generates an LED control signal designating the LED elements 21-1 to 21-N to be lit. The LED controller section 11 transmits the generated LED control signal to the LED module section 20 .
（表示装置による処理）
　次に、図５から図７を参照しつつ表示装置１による処理について説明する。図５は、表示装置１による処理の流れを示すフローチャートである。前提条件として、ＬＥＤモジュール部２０の横方向のＬＥＤ素子２１の数は、図２に示すように、７個であり、縦方向のＬＥＤ素子２１の数は、１０個であり、横方向のＬＥＤ素子２１のピッチ長は１００ｍｍであるとする。モジュールサイズ算出部１４は、横方向のＬＥＤ素子２１の数と、縦方向のＬＥＤ素子２１の数と、横方向のＬＥＤ素子２１のピッチ長を予め内部の記憶領域に記憶させている。ＬＥＤコントローラ部１１は、横方向のＬＥＤ素子２１の数と、縦方向のＬＥＤ素子２１の数とを予め内部の記憶領域に記憶させている。 (Processing by display device)
Next, processing by the display device 1 will be described with reference to FIGS. 5 to 7. FIG. FIG. 5 is a flow chart showing the flow of processing by the display device 1. As shown in FIG. As a prerequisite, the number of LED elements 21 in the horizontal direction of the LED module section 20 is seven, the number of LED elements 21 in the vertical direction is ten, as shown in FIG. Assume that the pitch length of the elements 21 is 100 mm. The module size calculator 14 stores the number of LED elements 21 in the horizontal direction, the number of LED elements 21 in the vertical direction, and the pitch length of the LED elements 21 in the horizontal direction in advance in an internal storage area. The LED controller unit 11 stores the number of LED elements 21 in the horizontal direction and the number of LED elements 21 in the vertical direction in advance in an internal storage area.
　また、図５に示すフローチャートの処理が開始される前に以下のことが行われる。利用者は、ＬＥＤモジュール部２０を設置する窓の窓枠の大きさに応じてＬＥＤモジュール部２０を縦方向に伸縮させて設置する。利用者は、映像信号出力装置２と、表示装置１を起動する。映像信号出力装置２は、起動すると映像信号を、電気回線を通じて表示装置１の映像信号制御部１０が備えるＬＥＤコントローラ部１１に送信する。以下、図５のフローチャートに示す処理が行われる。 Also, the following is performed before the processing of the flowchart shown in FIG. 5 is started. The user installs the LED module section 20 by expanding and contracting it in the vertical direction according to the size of the window frame of the window on which the LED module section 20 is to be installed. A user activates the video signal output device 2 and the display device 1 . When the video signal output device 2 is activated, it transmits a video signal to the LED controller section 11 included in the video signal control section 10 of the display device 1 through an electric line. Thereafter, the processing shown in the flowchart of FIG. 5 is performed.
　測定部２２は、距離Ｄを測定する。測定部２２は、測定した距離Ｄを示すデータを送受信部２３に出力する。送受信部２３は、測定部２２から受けた距離Ｄを示すデータをＬＥＤコントローラ設定部１２の測定データ受信部１３に送信する。測定データ受信部１３は、送受信部２３が送信する距離Ｄを示すデータを受信し、受信した距離Ｄを示すデータをモジュールサイズ算出部１４に出力する（ステップＳ１）。 The measurement unit 22 measures the distance D. The measurement unit 22 outputs data indicating the measured distance D to the transmission/reception unit 23 . The transmitting/receiving section 23 transmits the data indicating the distance D received from the measuring section 22 to the measurement data receiving section 13 of the LED controller setting section 12 . The measurement data receiving unit 13 receives the data indicating the distance D transmitted by the transmitting/receiving unit 23, and outputs the received data indicating the distance D to the module size calculating unit 14 (step S1).
　モジュールサイズ算出部１４は、測定部２２が測定した距離Ｄから最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の距離を算出する。ここで、モジュールサイズ算出部１４が算出する最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の距離が４５ｃｍであったとする。モジュールサイズ算出部１４は、内部の記憶領域が記憶する縦方向のＬＥＤ素子２１の数である「１０」から１を減算した「９」の値で、算出した距離４５ｃｍを除算することにより、縦方向のＬＥＤ素子２１のピッチ長として５ｃｍを算出する。 The module size calculator 14 calculates the distance D measured by the measuring unit 22 from the distance D measured by the uppermost LED element 21-1 and the lowermost LED element 21-64 located on a straight line in the vertical direction when viewed from the LED element 21-1. Calculate the distance between Here, the distance between the uppermost LED element 21-1 calculated by the module size calculating unit 14 and the lowermost LED element 21-64 located on a straight line in the vertical direction when viewed from the LED element 21-1 is is 45 cm. The module size calculation unit 14 divides the calculated distance of 45 cm by a value of “9” obtained by subtracting 1 from “10”, which is the number of LED elements 21 in the vertical direction stored in the internal storage area. 5 cm is calculated as the pitch length of the LED elements 21 in the direction.
　モジュールサイズ算出部１４は、算出した５ｃｍに、縦方向のＬＥＤ素子２１の数である「１０」を乗算して、表示画面の縦方向の長さである５０ｃｍを算出する。モジュールサイズ算出部１４は、内部の記憶領域が記憶する横方向のＬＥＤ素子２１のピッチ長である「１００ｍｍ」に、内部の記憶領域が記憶する横方向のＬＥＤ素子２１の数である「７」を乗算して、表示画面の横方向の長さである７０ｃｍを算出する。モジュールサイズ算出部１４は、算出した表示画面の横方向の長さである７０ｃｍと、算出した表示画面の縦方向の長さである５０ｃｍとを含むモジュールサイズを示すデータをデータ出力部１５に出力する（ステップＳ２）。 The module size calculator 14 multiplies the calculated 5 cm by "10", which is the number of LED elements 21 in the vertical direction, to calculate 50 cm, which is the vertical length of the display screen. The module size calculator 14 calculates the pitch length of the LED elements 21 in the horizontal direction stored in the internal storage area "100 mm" and the number of LED elements 21 in the horizontal direction stored in the internal storage area "7". to calculate 70 cm, which is the horizontal length of the display screen. The module size calculator 14 outputs to the data output unit 15 data indicating the module size including the calculated horizontal length of the display screen of 70 cm and the calculated vertical length of the display screen of 50 cm. (step S2).
　ＬＥＤコントローラ部１１は、伸縮構造体４０が伸縮する方向、すなわち、ＬＥＤモジュール部２０の縦方向の仮想解像度を算出する。Ｘを、スケーリング目標値の縦の仮想解像度とすると、「モジュールサイズの横方向の長さ（７０［ｃｍ］）：モジュールサイズの縦方向の長さ（５０［ｃｍ］）＝横方向の物理的解像度（７ピクセル）：縦方向の仮想解像度Ｘ」という関係式が成り立つことになる。この場合、縦方向の仮想解像度Ｘ＝５ピクセルになる。ＬＥＤコントローラ部１１は、映像信号出力装置２が送信する映像信号を受信する。ＬＥＤコントローラ部１１は、内部の記憶領域が記憶する横方向のＬＥＤ素子２１の数、すなわち横方向の物理的解像度である７ピクセルと、算出した縦方向の仮想解像度の５ピクセルとに基づいて、受信した映像信号をスケーリングする（ステップＳ３）。 The LED controller section 11 calculates the virtual resolution in the direction in which the expandable structure 40 expands and contracts, that is, the vertical direction of the LED module section 20 . Assuming that X is the vertical virtual resolution of the scaling target value, "horizontal length of module size (70 [cm]): vertical length of module size (50 [cm]) = horizontal physical resolution (7 pixels):vertical virtual resolution X" is established. In this case, the vertical virtual resolution is X=5 pixels. The LED controller section 11 receives a video signal transmitted by the video signal output device 2 . Based on the number of LED elements 21 in the horizontal direction stored in the internal storage area, that is, the physical resolution in the horizontal direction of 7 pixels, and the calculated virtual resolution in the vertical direction of 5 pixels, The received video signal is scaled (step S3).
　ＬＥＤコントローラ部１１は、スケーリングした映像信号に基づいてＬＥＤ制御信号を生成し、生成したＬＥＤ制御信号をＬＥＤモジュール部２０の送受信部２３に送信する（ステップＳ４）。ＬＥＤモジュール部２０の送受信部２３は、ＬＥＤコントローラ部１１が送信するＬＥＤ制御信号を受信し、受信したＬＥＤ制御信号をＬＥＤドライバ部２４に出力する。ＬＥＤドライバ部２４は、送受信部２３が出力するＬＥＤ制御信号を取り込み、取り込んだＬＥＤ制御信号において指定されているＬＥＤ素子２１－１～２１－Ｎを点灯させる（ステップＳ５）。 The LED controller section 11 generates an LED control signal based on the scaled video signal, and transmits the generated LED control signal to the transmission/reception section 23 of the LED module section 20 (step S4). The transmitting/receiving section 23 of the LED module section 20 receives the LED control signal transmitted by the LED controller section 11 and outputs the received LED control signal to the LED driver section 24 . The LED driver section 24 takes in the LED control signal output from the transmitting/receiving section 23, and lights up the LED elements 21-1 to 21-N specified in the received LED control signal (step S5).
　例えば、図６（Ａ）に示す窓７１の窓枠の縦方向の長さに対してＬＥＤモジュール部２０の表示画面の縦方向の長さが短い場合と、図７（Ａ）に示す窓７１の窓枠の縦方向の長さと、ＬＥＤモジュール部２０の表示画面の縦方向の長さとが同一、または、略同一の場合とにおいて、ＬＥＤコントローラ部１１が行うスケーリングについて説明する。図６（Ａ）に示す場合が、例えば、上記したモジュールサイズ算出部１４が算出する最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の距離が４５ｃｍの場合、すなわち、ＬＥＤモジュール部２０の表示画面の縦方向の長さが５０ｃｍ、横方向の長さが７０ｃｍの場合であるとする。この場合、上記したように、縦方向の仮想解像度は、５ピクセルになる。 For example, when the vertical length of the display screen of the LED module section 20 is shorter than the vertical length of the window frame of the window 71 shown in FIG. Scaling performed by the LED controller unit 11 when the vertical length of the window frame and the vertical length of the display screen of the LED module unit 20 are the same or substantially the same will be described. In the case shown in FIG. 6A, for example, the uppermost LED element 21-1 calculated by the module size calculating unit 14 and the lowermost stage positioned on a straight line in the vertical direction when viewed from the LED element 21-1. is 45 cm, that is, the display screen of the LED module section 20 has a vertical length of 50 cm and a horizontal length of 70 cm. In this case, as described above, the vertical virtual resolution is 5 pixels.
　これに対して、図７（Ａ）に示す場合、モジュールサイズ算出部１４が算出する最上段のＬＥＤ素子２１－１と、当該ＬＥＤ素子２１－１からみて縦方向の直線上に位置する最下段のＬＥＤ素子２１－６４との間の距離が８１ｃｍであるとする。この場合、ＬＥＤモジュール部２０の表示画面の縦方向の長さは、９０ｃｍ（＝８１／９×１０）になり、縦方向の仮想解像度は、９ピクセルになる。 On the other hand, in the case shown in FIG. 7A, the uppermost LED element 21-1 calculated by the module size calculator 14 and the lowermost LED element 21-1 located on a straight line in the vertical direction when viewed from the LED element 21-1 and the LED element 21-64 is 81 cm. In this case, the vertical length of the display screen of the LED module section 20 is 90 cm (=81/9×10), and the vertical virtual resolution is 9 pixels.
　ここで、映像信号出力装置２が出力する映像信号の１フレームの縦方向と横方向のピクセル数が、３１５ピクセル×３１５ピクセルであるとする。図６（Ａ）の場合、縦方向の仮想解像度が、５ピクセルであり、横方向の物理的解像度が、７ピクセルであるため、ＬＥＤコントローラ部１１は、映像信号の縦方向を１／６３に縮小し、横方向を１／４５に縮小するスケーリングを行うことになる。これに対して、図７（Ａ）の場合、縦方向の仮想解像度が、９ピクセルであり、横方向の物理的解像度が、７ピクセルであるため、ＬＥＤコントローラ部１１は、映像信号の縦方向を１／３５に縮小し、横方向を１／４５に縮小するスケーリングを行うことになる。 Here, it is assumed that the number of pixels in the vertical and horizontal directions of one frame of the video signal output by the video signal output device 2 is 315 pixels×315 pixels. In the case of FIG. 6A, the virtual resolution in the vertical direction is 5 pixels, and the physical resolution in the horizontal direction is 7 pixels. Scaling is performed to reduce the size and reduce the size to 1/45 in the horizontal direction. On the other hand, in the case of FIG. 7A, the virtual resolution in the vertical direction is 9 pixels, and the physical resolution in the horizontal direction is 7 pixels. is reduced to 1/35 and the horizontal direction is reduced to 1/45.
　ＬＥＤコントローラ部１１は、上記のようにしてスケーリングした映像信号に基づいてＬＥＤ制御信号を生成する。ＬＥＤドライバ部２４が、ＬＥＤコントローラ部１１が生成したＬＥＤ制御信号に基づいて、ＬＥＤ素子２１－１～２１－７０を点灯させると、図６（Ａ）の場合、図６（Ｂ）において符号６１により示す映像が表示され、図７（Ａ）の場合、図７（Ｂ）において符号６２により示す映像が表示されることになる。 The LED controller section 11 generates an LED control signal based on the video signal scaled as described above. When the LED driver unit 24 turns on the LED elements 21-1 to 21-70 based on the LED control signal generated by the LED controller unit 11, in the case of FIG. 6A, reference numeral 61 in FIG. is displayed, and in the case of FIG. 7A, the image indicated by reference numeral 62 in FIG. 7B is displayed.

The telescopic structure 40 includes a plurality of rod-shaped frames 30-1 to 30-10 arranged in parallel, and the LED elements 21-1 to 21-1 extending linearly in a direction perpendicular to the longitudinal direction of the rod-shaped frames 30-1 to 30-10. A plurality of rod-shaped frames 30-1 to 30-10 are supported so that 21-70 are arranged side by side, and the rod-shaped frames 30-1 to 30-10 are maintained at uniform or substantially uniform intervals. Stretch the distance between each of 30-1 to 30-10. The measuring section 22 measures the distance between the rod-shaped frames 30-1 and 30-10 at both ends. The video signal control unit 10 calculates the size of the display screen configured by the LED elements 21-1 to 21-70 based on the distance measured by the measurement unit 22, and calculates the size of the display screen and the vertical direction.
