　（第１の実施形態）
　本発明に係る表示装置の第１の実施形態について、図面を参照して説明する。図１に示すように、表示装置１０は、画像により車速を示す指針計を表示するグラフィックメータ表示装置である。 (First Embodiment)
A first embodiment of the display device according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the display device 10 is a graphic meter display device that displays a pointer meter indicating the vehicle speed by an image.

　図２に示すように、表示装置１０は、表示装置１０の全体を制御する制御部５５と、液晶パネル２０と、液晶パネル２０を照明する光源３０と、を備える。制御部５５は、マイコン（マイクロコンピュータ）５０と、マイコン５０による制御のもと液晶パネル２０に画像を描画するＧＤＣ（Graphic Display Controller）４０と、を備える。 As shown in FIG. 2, the display device 10 includes a control unit 55 that controls the entire display device 10, a liquid crystal panel 20, and a light source 30 that illuminates the liquid crystal panel 20. The control unit 55 includes a microcomputer (microcomputer) 50 and a GDC (Graphic Display Controller) 40 that draws an image on the liquid crystal panel 20 under the control of the microcomputer 50.

　ＧＤＣ４０は、マイコン５０による制御のもと、液晶パネル２０に画像を描画する。液晶パネル２０は、ＴＦＴ（Thin Film Transistor）型の液晶パネルであり、ＧＤＣ４０による制御のもと、画素毎に光透過率を調整する。
　光源３０は、ＬＥＤ（Light Emitting Diode）により構成され、マイコン５０による制御のもと、液晶パネル２０に光、例えば白色光を照射する。
　マイコン５０は、予め定められたプログラムに従って各種の制御を行うＣＰＵ５１と、ＣＰＵ５１が実行するプログラム、元画像等を格納したＲＯＭ５２と、各種データを格納するとともに、ＣＰＵ５１の処理作業に必要なワーキングエリアを有するＲＡＭ５３と、を備える。
　ＲＯＭ５２には、例えばメータ用の文字板を示す静止画像データと、この文字板上を回動する指針を示す指針画像データと、指針に対してブラー演出を行うためのブラー演出画像データと、各種の閾値ＴＨ１，ＴＨ２が記憶されている。
　マイコン５０は、外部から車速等を含む車両情報を取得し、ＧＤＣ４０を介して液晶パネル２０に車両情報を含む画像を表示する。 The GDC 40 draws an image on the liquid crystal panel 20 under the control of the microcomputer 50. The liquid crystal panel 20 is a TFT (Thin Film Transistor) type liquid crystal panel, and the light transmittance is adjusted for each pixel under the control of the GDC 40.
The light source 30 is composed of an LED (Light Emitting Diode), and under the control of a microcomputer 50, irradiates the liquid crystal panel 20 with light, for example, white light.
The microcomputer 50 stores a CPU 51 that performs various controls according to a predetermined program, a ROM 52 that stores a program executed by the CPU 51, an original image, and the like, and various data, and also provides a working area required for processing work of the CPU 51. The RAM 53 is provided.
The ROM 52 contains, for example, still image data indicating a dial for a meter, pointer image data indicating a pointer rotating on the dial, blur effect image data for performing a blur effect on the pointer, and various types. Thresholds TH1 and TH2 are stored.
The microcomputer 50 acquires vehicle information including vehicle speed and the like from the outside, and displays an image including vehicle information on the liquid crystal panel 20 via the GDC 40.

　マイコン５０は、ＧＤＣ４０を介して、静止画像データとして、図１に示すように、背景画像Ｉｂを表示する。背景画像Ｉｂにおいては、数字及び目盛に対応する部位は光を透過することにより白色で表示され、当該部位以外の背景は光を透過させないことにより黒色で表示される。 The microcomputer 50 displays the background image Ib as still image data via the GDC 40, as shown in FIG. In the background image Ib, the portion corresponding to the numerical value and the scale is displayed in white by transmitting light, and the background other than the portion is displayed in black by not transmitting light.

　マイコン５０は、ＧＤＣ４０を介して、指針画像データとして、図３に示すように、指針画像８０を表示する。指針画像８０は、白色の棒状に形成され、背景画像Ｉｂの数値と目盛に対して指針画像８０の下端部を中心に回動する。指針画像８０は、指針画像８０の全域にわたって同一の光透過率に設定される。マイコン５０は、所定の周期（例えば１／６０秒）毎に、外部から車速を含む車両情報を取得し、指針画像８０の位置を更新する。これにより、指針画像８０は車速に応じて回動する。 The microcomputer 50 displays the pointer image 80 as the pointer image data via the GDC 40, as shown in FIG. The pointer image 80 is formed in the shape of a white rod, and rotates about the lower end portion of the pointer image 80 with respect to the numerical value and the scale of the background image Ib. The pointer image 80 is set to have the same light transmittance over the entire area of the pointer image 80. The microcomputer 50 acquires vehicle information including the vehicle speed from the outside at a predetermined cycle (for example, 1/60 second) and updates the position of the pointer image 80. As a result, the pointer image 80 rotates according to the vehicle speed.

　マイコン５０は、ＧＤＣ４０を介して、ブラー演出画像データとして、図３、図４及び図５に示すように、指針画像８０のぶれを表現するブラー指針画像６０，７１，７２を表示する。
　図３及び図４（ｃ）に示すように、ブラー指針画像６０は、指針画像８０から離れた位置であって、指針画像８０の回動方向と反対方向に位置し、グラデーションが付けられた白色の棒状に形成される。ブラー指針画像６０は、指針画像８０の回動速度が閾値ＴＨ２以上で回転しているときに指針画像８０の残像を表現するために表示される。例えば、指針画像８０が時計回り方向Ｃｗに回転しているときには、図３に示すように、ブラー指針画像６０は指針画像８０の反時計回り方向Ｕｃｗの位置に表示される。一方、指針画像８０が反時計回り方向Ｕｃｗに回転しているときには、図示しないが、ブラー指針画像６０は指針画像８０の時計回り方向Ｃｗの位置に表示される。ブラー指針画像６０は、指針画像８０の移動軌跡を表現するため、指針画像８０の速度及び加速度に合わせて指針画像８０に対する表示位置が制御部５５により設定される。よって、ブラー指針画像７１，７２に比べてブラー指針画像６０を表示するための制御部５５の処理負担は大きくなる。 The microcomputer 50 displays the blur pointer images 60, 71, 72 that express the blurring of the pointer image 80 as the blur effect image data via the GDC 40, as shown in FIGS. 3, 4, and 5.
As shown in FIGS. 3 and 4 (c), the blur pointer image 60 is located at a position away from the pointer image 80 and in the direction opposite to the rotation direction of the pointer image 80, and is white with gradation. It is formed in the shape of a rod. The blur pointer image 60 is displayed to represent an afterimage of the pointer image 80 when the rotation speed of the pointer image 80 is rotating at a threshold value TH2 or higher. For example, when the pointer image 80 is rotating in the clockwise direction Cw, the blur pointer image 60 is displayed at the position of the pointer image 80 in the counterclockwise direction Ucw, as shown in FIG. On the other hand, when the pointer image 80 is rotating in the counterclockwise direction Ucw, the blur pointer image 60 is displayed at the position of the pointer image 80 in the clockwise direction Cw, although not shown. In order to express the movement locus of the pointer image 80 in the blur pointer image 60, the display position with respect to the pointer image 80 is set by the control unit 55 according to the speed and acceleration of the pointer image 80. Therefore, the processing load of the control unit 55 for displaying the blur pointer image 60 is larger than that of the blur pointer images 71 and 72.

　図４（ｃ）に示すように、ブラー指針画像６０は、ブラー指針画像６０の回動方向において中心から外側に向かうにつれて光透過率が低下するように、かつ、回動方向に直交する径方向内側に向かうにつれて光透過率が低下するようにグラデーションが設定される。ブラー指針画像６０の回動方向（図４の左右方向）の幅は、径方向内側（図４の下方向）に向かうにつれて小さくなるように形成される。 As shown in FIG. 4C, the blur pointer image 60 has a radial direction perpendicular to the rotation direction so that the light transmittance decreases from the center to the outside in the rotation direction of the blur pointer image 60. The gradation is set so that the light transmittance decreases toward the inside. The width of the blur pointer image 60 in the rotation direction (left-right direction in FIG. 4) is formed so as to decrease toward the inside in the radial direction (downward in FIG. 4).

　図４（ａ），（ｂ）に示すように、ブラー指針画像７１，７２は、指針画像８０の周囲を囲む枠状をなし、指針画像８０の回動に伴い移動する。
　図４（ａ）に示すように、ブラー指針画像７１は、指針画像８０の回動速度が閾値ＴＨ１以上で、指針画像８０が時計回り方向Ｃｗに回転する際に表示される。ブラー指針画像７１は、指針画像８０に重なる領域に形成されるくり抜き部７１ａと、くり抜き部７１ａに対して時計回り方向Ｃｗに形成される時計回り側画像部７１ｂと、くり抜き部７１ａに対して反時計回り方向Ｕｃｗに形成される反時計回り側画像部７１ｃと、を備える。
　図５（ａ）に示すように、くり抜き部７１ａにおいては指針画像８０が表示される。時計回り側画像部７１ｂ及び反時計回り側画像部７１ｃは、指針画像８０の回転中心側（図５の下側）に向かうにつれて、指針画像８０の回動方向に沿う幅Ｗが短くなるように形成される。すなわち、時計回り側画像部７１ｂ及び反時計回り側画像部７１ｃは扇状に形成される。反時計回り側画像部７１ｃの幅Ｗは、時計回り側画像部７１ｂの幅Ｗよりも長く形成される。言い換えると、反時計回り側画像部７１ｃの面積は時計回り側画像部７１ｂの面積よりも大きい。反時計回り側画像部７１ｃの明度は、指針画像８０の明度よりも低く、かつ時計回り側画像部７１ｂの明度よりも高く設定されている。すなわち、各明度の大小関係は、「指針画像８０の明度＞反時計回り側画像部７１ｃの明度＞時計回り側画像部７１ｂの明度」のように設定されている。このように各明度を設定することにより、より自然なブラー演出を行うことができる。
　この大小関係の比較に係る明度は、指針画像８０、反時計回り側画像部７１ｃ及び時計回り側画像部７１ｂにおける各領域の平均的な明度であってもよいし、各領域の最高の明度であってもよい。
　なお、明度は、液晶パネル２０の光透過率が上げられること、又は光源３０の出力が上げられることにより高められる。 As shown in FIGS. 4A and 4B, the blur pointer images 71 and 72 form a frame shape surrounding the pointer image 80 and move with the rotation of the pointer image 80.
As shown in FIG. 4A, the blur pointer image 71 is displayed when the rotation speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the pointer image 80 rotates in the clockwise direction Cw. The blur pointer image 71 is opposite to the hollow portion 71a formed in the region overlapping the pointer image 80, the clockwise side image portion 71b formed in the clockwise direction Cw with respect to the hollow portion 71a, and the hollow portion 71a. A counterclockwise side image unit 71c formed in the clockwise direction Ucw is provided.
As shown in FIG. 5A, the pointer image 80 is displayed in the hollowed out portion 71a. The clockwise side image portion 71b and the counterclockwise side image portion 71c have a width W along the rotation direction of the pointer image 80 becoming shorter toward the rotation center side (lower side of FIG. 5) of the pointer image 80. It is formed. That is, the clockwise side image portion 71b and the counterclockwise side image portion 71c are formed in a fan shape. The width W of the counterclockwise image unit 71c is formed longer than the width W of the clockwise image unit 71b. In other words, the area of the counterclockwise image unit 71c is larger than the area of the clockwise image unit 71b. The brightness of the counterclockwise image unit 71c is set lower than the brightness of the pointer image 80 and higher than the brightness of the clockwise image unit 71b. That is, the magnitude relationship of each brightness is set as "brightness of the pointer image 80> brightness of the counterclockwise image unit 71c> brightness of the clockwise image unit 71b". By setting each brightness in this way, a more natural blur effect can be performed.
The brightness related to the comparison of the magnitude relationship may be the average brightness of each region in the pointer image 80, the counterclockwise side image portion 71c, and the clockwise side image portion 71b, or the highest brightness of each region. There may be.
The brightness is increased by increasing the light transmittance of the liquid crystal panel 20 or increasing the output of the light source 30.

　図４（ｂ）及び図５（ｂ）に示すように、ブラー指針画像７２は、指針画像８０の回動速度が閾値ＴＨ１以上で、指針画像８０が反時計回り方向Ｕｃｗに回転する際に表示される。ブラー指針画像７２は、指針画像８０に重なる領域に形成されるくり抜き部７２ａと、くり抜き部７２ａに対して時計回り方向Ｃｗに形成される時計回り側画像部７２ｂと、くり抜き部７２ａに対して反時計回り方向Ｕｃｗに形成される反時計回り側画像部７２ｃと、を備える。図５（ｂ）に示すように、くり抜き部７２ａにおいては指針画像８０が表示される。時計回り側画像部７２ｂ及び反時計回り側画像部７２ｃは、指針画像８０の回転中心側（図５の下側）に向かうにつれて、指針画像８０の回動方向に沿う幅Ｗが短くなるように形成される。すなわち、時計回り側画像部７２ｂ及び反時計回り側画像部７２ｃは扇状に形成される。反時計回り側画像部７２ｃの幅Ｗは、時計回り側画像部７２ｂの幅Ｗよりも短く形成される。言い換えると、反時計回り側画像部７２ｃの面積は時計回り側画像部７２ｂの面積よりも小さい。時計回り側画像部７２ｂの明度は、指針画像８０の明度よりも低く、かつ反時計回り側画像部７２ｃの明度よりも高く設定されている。すなわち、各明度の大小関係は、「指針画像８０の明度＞時計回り側画像部７２ｂの明度＞反時計回り側画像部７２ｃの明度」のように設定されている。このように各明度を設定することにより、より自然なブラー演出を行うことができる。 As shown in FIGS. 4 (b) and 5 (b), the blur pointer image 72 is displayed when the rotation speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the pointer image 80 rotates in the counterclockwise direction Ucw. Will be done. The blur pointer image 72 is opposite to the hollow portion 72a formed in the region overlapping the pointer image 80, the clockwise side image portion 72b formed in the clockwise direction Cw with respect to the hollow portion 72a, and the hollow portion 72a. A counterclockwise side image unit 72c formed in the clockwise direction Ucw is provided. As shown in FIG. 5B, the pointer image 80 is displayed in the hollow portion 72a. The clockwise side image portion 72b and the counterclockwise side image portion 72c are arranged so that the width W along the rotation direction of the pointer image 80 becomes shorter toward the rotation center side (lower side of FIG. 5) of the pointer image 80. It is formed. That is, the clockwise side image portion 72b and the counterclockwise side image portion 72c are formed in a fan shape. The width W of the counterclockwise image unit 72c is formed shorter than the width W of the clockwise image unit 72b. In other words, the area of the counterclockwise image unit 72c is smaller than the area of the clockwise image unit 72b. The brightness of the clockwise image unit 72b is set lower than the brightness of the pointer image 80 and higher than the brightness of the counterclockwise image unit 72c. That is, the magnitude relationship of each brightness is set as "brightness of the pointer image 80> brightness of the clockwise side image unit 72b> brightness of the counterclockwise side image unit 72c". By setting each brightness in this way, a more natural blur effect can be performed.

　次に、図６のフローチャートを参照しつつ、マイコン５０による指針表示処理について説明する。この指針表示処理は繰り返し実行される。
　まず、マイコン５０は、指針画像８０の回動速度が閾値ＴＨ１以上であるか否かを判定する（ステップＳ１０１）。閾値ＴＨ１は、例えば、２０～３０ｄｅｇ／ｓｅｃに設定される。マイコン５０は、指針画像８０の回動速度が閾値ＴＨ１未満である旨判定したとき（ステップＳ１０１；ＮＯ）、指針画像８０の回動速度が低速領域であるとして、指針画像８０のみを表示し、ブラー指針画像６０，７１，７２を表示せず（ステップＳ１０２）、当該指針表示処理を終了する。 Next, the pointer display process by the microcomputer 50 will be described with reference to the flowchart of FIG. This guideline display process is repeatedly executed.
First, the microcomputer 50 determines whether or not the rotation speed of the pointer image 80 is equal to or higher than the threshold value TH1 (step S101). The threshold TH1 is set to, for example, 20 to 30 deg / sec. When the microcomputer 50 determines that the rotation speed of the pointer image 80 is less than the threshold value TH1 (step S101; NO), the microcomputer 50 displays only the pointer image 80, assuming that the rotation speed of the pointer image 80 is in the low speed region. The blur pointer images 60, 71, and 72 are not displayed (step S102), and the pointer display process is terminated.

　一方、マイコン５０は、指針画像８０の回動速度が閾値ＴＨ１以上である旨判定したとき（ステップＳ１０１；ＹＥＳ）、指針画像８０の回動速度が閾値ＴＨ２以上であるか否かを判定する（ステップＳ１０３）。閾値ＴＨ２は、例えば、４０～５０ｄｅｇ／ｓｅｃに設定される。マイコン５０は、指針画像８０の回動速度が閾値ＴＨ２未満である旨判定したとき（ステップＳ１０３；ＮＯ）、指針画像８０の回動速度が中速領域であるとして、指針画像８０の回動方向が時計回り方向Ｃｗであるか否かを判定する（ステップＳ１０４）。
　マイコン５０は、指針画像８０の回動方向が時計回り方向Ｃｗである旨判定すると（ステップＳ１０４；ＹＥＳ）、指針画像８０と１つのブラー指針画像７１を表示し（ステップＳ１０５）、当該指針表示処理を終了する。
　一方、マイコン５０は、指針画像８０の回動方向が時計回り方向Ｃｗでない、すなわち、反時計回り方向Ｕｃｗである旨判定すると（ステップＳ１０４；ＮＯ）、指針画像８０と１つのブラー指針画像７２を表示し（ステップＳ１０６）、当該指針表示処理を終了する。
　上記ステップＳ１０５，Ｓ１０６のブラー指針画像７１，７２により、指針画像８０の回動速度が中速領域である場合には、比較的に軽い処理負担にて、指針画像８０の回動方向に応じたブラー演出が可能となる。 On the other hand, when the microcomputer 50 determines that the rotation speed of the pointer image 80 is equal to or higher than the threshold TH1 (YES), the microcomputer 50 determines whether or not the rotation speed of the pointer image 80 is equal to or higher than the threshold TH2 (step S101; YES). Step S103). The threshold TH2 is set to, for example, 40 to 50 deg / sec. When the microcomputer 50 determines that the rotation speed of the pointer image 80 is less than the threshold value TH2 (step S103; NO), it is assumed that the rotation speed of the pointer image 80 is in the medium speed region, and the rotation direction of the pointer image 80 Is determined to be in the clockwise direction Cw (step S104).
When the microcomputer 50 determines that the rotation direction of the pointer image 80 is the clockwise direction Cw (step S104; YES), the microcomputer 50 displays the pointer image 80 and one blur pointer image 71 (step S105), and the pointer display process. To finish.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is not the clockwise direction Cw, that is, the counterclockwise direction Ucw (step S104; NO), the pointer image 80 and one blur pointer image 72 are displayed. It is displayed (step S106), and the guideline display process is terminated.
According to the blur pointer images 71 and 72 in steps S105 and S106, when the rotation speed of the pointer image 80 is in the medium speed region, the rotation direction of the pointer image 80 is adjusted with a relatively light processing load. Blur production is possible.

　一方、マイコン５０は、指針画像８０の回動速度が閾値ＴＨ２以上である旨判定したとき（ステップＳ１０３；ＹＥＳ）、指針画像８０の回動速度が高速領域であるとして、指針画像８０の回動方向が時計回り方向Ｃｗであるか否かを判定する（ステップＳ１０７）。マイコン５０は、指針画像８０の回動方向が時計回り方向Ｃｗである旨判定すると（ステップＳ１０７；ＹＥＳ）、指針画像８０と２つのブラー指針画像６０，７１を表示し（ステップＳ１０８）、当該指針表示処理を終了する。ここでは、２つのブラー指針画像６０，７１が表示されるため、上記ステップＳ１０５よりもブラー演出が強められる。よって、指針画像８０の回動速度が高速である場合も自然なブラー演出が可能となる。
　一方、マイコン５０は、指針画像８０の回動方向が時計回り方向Ｃｗでない、すなわち、反時計回り方向Ｕｃｗである旨判定すると（ステップＳ１０７；ＮＯ）、指針画像８０と２つのブラー指針画像６０，７２を表示し（ステップＳ１０９）、当該指針表示処理を終了する。ここでは、２つのブラー指針画像６０，７２が表示されるため、上記ステップＳ１０６よりもブラー演出が強められる。よって、指針画像８０の回動速度が高速である場合も自然なブラー演出が可能となる。
　以上で、指針表示処理の説明が終了となる。 On the other hand, when the microcomputer 50 determines that the rotation speed of the pointer image 80 is equal to or higher than the threshold value TH2 (step S103; YES), the microcomputer 50 assumes that the rotation speed of the pointer image 80 is in the high speed region, and rotates the pointer image 80. It is determined whether or not the direction is the clockwise direction Cw (step S107). When the microcomputer 50 determines that the rotation direction of the pointer image 80 is the clockwise direction Cw (step S107; YES), the microcomputer 50 displays the pointer image 80 and the two blur pointer images 60 and 71 (step S108), and the pointer image 80 is displayed. End the display process. Here, since the two blur pointer images 60 and 71 are displayed, the blur effect is strengthened as compared with step S105. Therefore, even when the rotation speed of the pointer image 80 is high, a natural blur effect can be produced.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is not the clockwise direction Cw, that is, the counterclockwise direction Ucw (step S107; NO), the pointer image 80 and the two blur pointer images 60, 72 is displayed (step S109), and the guideline display process is terminated. Here, since the two blur pointer images 60 and 72 are displayed, the blur effect is strengthened as compared with step S106. Therefore, even when the rotation speed of the pointer image 80 is high, a natural blur effect can be produced.
This is the end of the explanation of the guideline display process.

　次に、指針画像８０が原位置から目標位置に時計回り方向Ｃｗに回動し、目標位置で停止する際の作用について説明する。
　指針画像８０が原位置から目標位置に向けて徐々に回動速度が上昇していく。指針画像８０の回動速度が閾値ＴＨ１未満にあるとき、指針画像８０が表示され、ブラー指針画像７１，７２が表示されない。そして、指針画像８０の回動速度が上昇し、指針画像８０の回動速度が閾値ＴＨ１以上で、かつ閾値ＴＨ２未満となったときに、ブラー指針画像７１が表示される。ブラー指針画像７１は指針画像８０と一体で移動する。
　さらに、指針画像８０が目標位置に向けて指針画像８０の回動速度が上昇し、指針画像８０の回動速度が閾値ＴＨ２以上となったときに、ブラー指針画像７１を維持しつつブラー指針画像６０が表示される。ブラー指針画像６０の表示位置は、指針画像８０の速度及び加速度に合わせて制御部５５により設定される。 Next, the action when the pointer image 80 rotates from the original position to the target position in the clockwise direction Cw and stops at the target position will be described.
The rotation speed of the pointer image 80 gradually increases from the original position to the target position. When the rotation speed of the pointer image 80 is less than the threshold value TH1, the pointer image 80 is displayed and the blur pointer images 71 and 72 are not displayed. Then, when the rotation speed of the pointer image 80 increases and the rotation speed of the pointer image 80 is equal to or more than the threshold value TH1 and less than the threshold value TH2, the blur pointer image 71 is displayed. The blur pointer image 71 moves integrally with the pointer image 80.
Further, when the rotation speed of the pointer image 80 increases toward the target position of the pointer image 80 and the rotation speed of the pointer image 80 becomes the threshold value TH2 or more, the blur pointer image 71 is maintained while the blur pointer image is maintained. 60 is displayed. The display position of the blur pointer image 60 is set by the control unit 55 according to the speed and acceleration of the pointer image 80.

　そして、指針画像８０が目標位置に近づくにつれて徐々に回動速度が減少し、指針画像８０の回動速度が閾値ＴＨ２未満となったときに、ブラー指針画像７１を維持しつつブラー指針画像６０が消去される。
　さらに、指針画像８０の回動速度が減少し、指針画像８０の回動速度が閾値ＴＨ１未満となったときに、ブラー指針画像７１が消去される。そして、ブラー指針画像７１，６０なしで指針画像８０が目標位置に到達する。
　なお、指針画像８０が原位置から目標位置に反時計回り方向Ｕｃｗに回動する場合、ブラー指針画像７１に代えてブラー指針画像７２が表示される点を除き、上記の作用と同様である。 Then, as the pointer image 80 approaches the target position, the rotation speed gradually decreases, and when the rotation speed of the pointer image 80 becomes less than the threshold value TH2, the blur pointer image 60 keeps the blur pointer image 71. It will be erased.
Further, when the rotation speed of the pointer image 80 decreases and the rotation speed of the pointer image 80 becomes less than the threshold value TH1, the blur pointer image 71 is erased. Then, the pointer image 80 reaches the target position without the blur pointer images 71 and 60.
When the pointer image 80 rotates from the original position to the target position in the counterclockwise direction Ucw, the action is the same as described above except that the blur pointer image 72 is displayed instead of the blur pointer image 71.

　（効果）
　以上、説明した第１の実施形態によれば、以下の効果を奏する。
　（１）表示装置１０は、指示部の一例である指針画像８０を含む画像を表示する表示部の一例である液晶パネル２０と、液晶パネル２０を制御し、画像内で指針画像８０を移動させる制御部５５と、を備える。制御部５５は、指針画像８０の移動速度が閾値ＴＨ１以上であり、かつ、指針画像８０の回動方向が時計回り方向Ｃｗであるときには指針画像８０の進行方向に位置する進行方向画像部の一例である時計回り側画像部７１ｂを含むブラー画像の一例であるブラー指針画像７１を表示する。一方、制御部５５は、指針画像８０の移動速度が閾値ＴＨ１以上であり、かつ、指針画像８０の回動方向が反時計回り方向Ｕｃｗであるときには指針画像８０の進行方向に位置する進行方向画像部の一例である反時計回り側画像部７２ｃを有するブラー指針画像７２を表示する。
　この構成によれば、指針画像８０の進行方向にブラー指針画像７１の時計回り側画像部７１ｂ又はブラー指針画像７２の反時計回り側画像部７２ｃが表示される。これにより、液晶パネル２０の応答性の遅れを補うことができる。また、従来の指針画像の軌跡方向にのみブラー指針画像が表示される場合に比べて、指針画像８０の移動をより滑らかに見せることができ、より自然なブラー演出が可能となる。 (effect)
According to the first embodiment described above, the following effects are obtained.
(1) The display device 10 controls a liquid crystal panel 20 and a liquid crystal panel 20 as an example of a display unit for displaying an image including a pointer image 80 which is an example of an instruction unit, and moves the pointer image 80 within the image. It includes a control unit 55. The control unit 55 is an example of a traveling direction image unit located in the traveling direction of the pointer image 80 when the moving speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the rotation direction of the pointer image 80 is clockwise Cw. A blur pointer image 71, which is an example of a blur image including the clockwise side image portion 71b, is displayed. On the other hand, when the moving speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the control unit 55 is located in the traveling direction of the pointer image 80. A blur pointer image 72 having a counterclockwise side image portion 72c, which is an example of the portion, is displayed.
According to this configuration, the clockwise image portion 71b of the blur pointer image 71 or the counterclockwise image portion 72c of the blur pointer image 72 is displayed in the traveling direction of the pointer image 80. This makes it possible to compensate for the delay in the responsiveness of the liquid crystal panel 20. Further, as compared with the case where the blur pointer image is displayed only in the locus direction of the conventional pointer image, the movement of the pointer image 80 can be made to appear smoother, and a more natural blur effect can be achieved.

　（２）ブラー指針画像７１は、指針画像８０の移動速度が閾値ＴＨ１以上であり、かつ、指針画像８０の回動方向が時計回り方向Ｃｗである場合、時計回り側画像部７１ｂに加えて、指針画像８０の軌跡方向に位置する軌跡方向画像部の一例である反時計回り側画像部７１ｃを含む。時計回り側画像部７１ｂの明度は反時計回り側画像部７１ｃの明度よりも低く設定される。一方、ブラー指針画像７２は、指針画像８０の移動速度が閾値ＴＨ１以上であり、かつ、指針画像８０の回動方向が反時計回り方向Ｕｃｗである場合、反時計回り側画像部７２ｃに加えて、指針画像８０の軌跡方向に位置する軌跡方向画像部の一例である時計回り側画像部７２ｂを含む。反時計回り側画像部７２ｃの明度は時計回り側画像部７２ｂの明度よりも低く設定される。
　この構成によれば、指針画像８０の回動方向に応じて、反時計回り側画像部７１ｃ，７２ｃの明度と時計回り側画像部７１ｂ，７２ｂの明度が調整されることにより、より自然なブラー演出が可能となる。 (2) When the moving speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the rotation direction of the pointer image 80 is the clockwise direction Cw, the blur pointer image 71 is added to the clockwise image portion 71b. The counterclockwise side image unit 71c, which is an example of the locus direction image unit located in the locus direction of the pointer image 80, is included. The brightness of the clockwise image unit 71b is set lower than the brightness of the counterclockwise image unit 71c. On the other hand, in the blur pointer image 72, when the moving speed of the pointer image 80 is equal to or higher than the threshold value TH1 and the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the blur pointer image 72 is added to the counterclockwise side image unit 72c. , The clockwise side image unit 72b which is an example of the locus direction image unit located in the locus direction of the pointer image 80 is included. The brightness of the counterclockwise image unit 72c is set lower than the brightness of the clockwise image unit 72b.
According to this configuration, the brightness of the counterclockwise image portions 71c and 72c and the brightness of the clockwise image portions 71b and 72b are adjusted according to the rotation direction of the pointer image 80, so that the blur is more natural. Directing is possible.

　（３）ブラー指針画像７１，７２には、ブラー指針画像７１，７２が指針画像８０に重ならないように指針画像８０に対応する領域がくり抜かれたくり抜き部７１ａ，７２ａが形成される。
　この構成によれば、ブラー指針画像７１，７２が指針画像８０に重なることが抑制され、これにより、ブラー指針画像７１，７２が指針画像８０に重なったときに重複領域の明度が上がることが抑制され、ひいては、重複領域が発光して見えることが抑制される。 (3) The blur pointer images 71 and 72 are formed with hollow portions 71a and 72a in which a region corresponding to the pointer image 80 is hollowed out so that the blur pointer images 71 and 72 do not overlap the pointer image 80.
According to this configuration, it is suppressed that the blur pointer images 71 and 72 overlap with the pointer image 80, and thereby the brightness of the overlapping region is suppressed when the blur pointer images 71 and 72 overlap with the pointer image 80. As a result, it is suppressed that the overlapping region appears to emit light.

　（４）制御部５５は、指針画像８０の移動速度が第１閾値の一例である閾値ＴＨ１以上であるときには第１ブラー指針画像の一例であるブラー指針画像７１，７２を表示し、指針画像８０が閾値ＴＨ１より大きい第２閾値の一例である閾値ＴＨ２以上であるときには指針画像８０の軌跡方向であって指針画像８０から離れた位置に第２ブラー指針画像の一例であるブラー指針画像６０を表示する。
　ブラー指針画像６０によりブラー演出を行う場合、指針画像８０の速度及び加速度に合わせてブラー指針画像６０の位置を設定する必要があり、ブラー指針画像７１，７２によりブラー演出を行う場合に比べて制御部５５の処理負担が大きくなる。上記構成によれば、指針画像８０の移動速度が閾値ＴＨ１以上で、かつ閾値ＴＨ２未満である場合には、ブラー指針画像６０によりブラー演出が行われない。このため、制御部５５の処理負担を低減することができる。 (4) When the moving speed of the pointer image 80 is equal to or higher than the threshold TH1 which is an example of the first threshold value, the control unit 55 displays the blur pointer images 71 and 72 which are examples of the first blur pointer image, and the pointer image 80. Is greater than the threshold TH1 and is an example of a second threshold. When the threshold is TH2 or higher, the blur pointer image 60, which is an example of the second blur pointer image, is displayed at a position in the locus direction of the pointer image 80 and away from the pointer image 80. To do.
When the blur effect is performed by the blur pointer image 60, it is necessary to set the position of the blur pointer image 60 according to the speed and acceleration of the pointer image 80, and it is controlled as compared with the case where the blur effect is performed by the blur pointer images 71 and 72. The processing load of the unit 55 becomes large. According to the above configuration, when the moving speed of the pointer image 80 is equal to or higher than the threshold value TH1 and less than the threshold value TH2, the blurring effect is not performed by the blur pointer image 60. Therefore, the processing load of the control unit 55 can be reduced.

　（第２の実施形態）
　本発明に係る表示装置の第２の実施形態について、図面を参照して説明する。以下、第１の実施形態との相違点を中心に説明する。
　本実施形態では、第１の実施形態に係るブラー指針画像７１，７２に代えて、図７に示すように、ブラー指針画像７３が表示される。
　ブラー指針画像７３は、ブラー指針画像７１，７２と同様に、くり抜き部７３ａと、時計回り側画像部７３ｂと、反時計回り側画像部７３ｃと、を備える。時計回り側画像部７３ｂ及び反時計回り側画像部７３ｃはそれぞれ同一の幅Ｗを有する。指針画像８０の回動方向に応じて、ブラー指針画像７３における時計回り側画像部７３ｂ及び反時計回り側画像部７３ｃの明度のバランスが調整される。
　図８に示すように、指針画像８０の回動方向が時計回り方向Ｃｗである場合、ブラー指針画像７３において時計回り側画像部７３ｂの明度が反時計回り側画像部７３ｃの明度よりも低く設定された時計回り用ブラー指針画像７３Ｃｗが表示される。
　一方、指針画像８０の回動方向が反時計回り方向Ｕｃｗである場合、ブラー指針画像７３において反時計回り側画像部７３ｃの明度が時計回り側画像部７３ｂの明度よりも低く設定された反時計回り用ブラー指針画像７３Ｕｃｗが表示される。 (Second Embodiment)
A second embodiment of the display device according to the present invention will be described with reference to the drawings. Hereinafter, the differences from the first embodiment will be mainly described.
In the present embodiment, instead of the blur guideline images 71 and 72 according to the first embodiment, the blur guideline image 73 is displayed as shown in FIG.
Similar to the blur pointer images 71 and 72, the blur pointer image 73 includes a hollow portion 73a, a clockwise side image portion 73b, and a counterclockwise side image portion 73c. The clockwise side image unit 73b and the counterclockwise side image unit 73c each have the same width W. The balance of brightness of the clockwise side image portion 73b and the counterclockwise side image portion 73c in the blur pointer image 73 is adjusted according to the rotation direction of the pointer image 80.
As shown in FIG. 8, when the rotation direction of the pointer image 80 is the clockwise direction Cw, the brightness of the clockwise side image portion 73b is set lower than the brightness of the counterclockwise side image portion 73c in the blur pointer image 73. The clockwise blur pointer image 73Cw is displayed.
On the other hand, when the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the brightness of the counterclockwise image unit 73c is set lower than the brightness of the clockwise image unit 73b in the blur pointer image 73. The rotation blur pointer image 73Ucw is displayed.

　次に、ブラー指針画像７３の生成方法について説明する。
　マイコン５０は、ＲＯＭ５２に格納された図８に示す元ブラー画像１７３を読み出す。元ブラー画像１７３は、くり抜き部１７３ａと、時計回り側画像部１７３ｂと、反時計回り側画像部１７３ｃと、を備える。時計回り側画像部１７３ｂ及び反時計回り側画像部１７３ｃの明度はそれぞれ初期値に設定されている。
　マイコン５０は、指針画像８０の回動方向が反時計回り方向Ｕｃｗである旨判定すると、反時計回り側画像部１７３ｃの明度を時計回り側画像部１７３ｂの明度よりも低く設定することによりブラー指針画像７３として反時計回り用ブラー指針画像７３Ｕｃｗを生成する。
　一方、マイコン５０は、指針画像８０の回動方向が時計回り方向Ｃｗである旨判定すると、時計回り側画像部１７３ｂの明度を反時計回り側画像部１７３ｃの明度よりも低く設定することによりブラー指針画像７３として時計回り用ブラー指針画像７３Ｃｗを生成する。
　マイコン５０は、生成したブラー指針画像７３を液晶パネル２０に表示する。
　以上のように、１つの元ブラー画像１７３から、時計回り用ブラー指針画像７３Ｃｗと反時計回り用ブラー指針画像７３Ｕｃｗが生成可能となる。 Next, a method of generating the blur pointer image 73 will be described.
The microcomputer 50 reads out the original blur image 173 shown in FIG. 8 stored in the ROM 52. The original blur image 173 includes a hollow portion 173a, a clockwise image portion 173b, and a counterclockwise image portion 173c. The brightness of the clockwise side image unit 173b and the counterclockwise side image unit 173c are set to initial values, respectively.
When the microcomputer 50 determines that the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the blur pointer is set by setting the brightness of the counterclockwise image unit 173c to be lower than the brightness of the clockwise image unit 173b. A counterclockwise blur pointer image 73Ucw is generated as the image 73.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is the clockwise direction Cw, it blurs by setting the brightness of the clockwise side image unit 173b to be lower than the brightness of the counterclockwise side image unit 173c. A clockwise blur pointer image 73Cw is generated as the pointer image 73.
The microcomputer 50 displays the generated blur pointer image 73 on the liquid crystal panel 20.
As described above, the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw can be generated from one original blur image 173.

　（効果）
　以上、説明した第２の実施形態によれば、以下の効果を奏する。
　（１）表示装置１０は、時計回り側画像部１７３ｂ、及び時計回り側画像部１７３ｂよりも反時計回り方向Ｕｃｗに位置する反時計回り側画像部１７３ｃが合成された１つの元ブラー画像１７３を記憶する記憶部の一例であるＲＯＭ５２を備える。制御部５５は、指針画像８０が時計回り方向Ｃｗに回転する場合には、元ブラー画像１７３における時計回り側画像部１７３ｂの明度を反時計回り側画像部１７３ｃよりも低く設定することにより時計回り用ブラー指針画像７３Ｃｗを生成し、指針画像８０が反時計回り方向Ｕｃｗに回転する場合には元ブラー画像１７３における反時計回り側画像部１７３ｃの明度を時計回り側画像部１７３ｂよりも低く設定することにより反時計回り用ブラー指針画像７３Ｕｃｗを生成する。
　１つの元ブラー画像１７３における時計回り側画像部１７３ｂの明度と反時計回り側画像部１７３ｃの明度を調整するだけで、時計回り用ブラー指針画像７３Ｃｗと反時計回り用ブラー指針画像７３Ｕｃｗが生成可能となる。よって、２つの元ブラー画像を用意する必要がなく、マイコン５０のＲＯＭ５２に記憶される画像データ量を低減することができる。
　また、時計回り側画像部７３ｂと反時計回り側画像部７３ｃの両方が表示されることで、時計回り側画像部７３ｂと反時計回り側画像部７３ｃの境界が目立たなくなり、より違和感の少ないブラー指針画像７３を表示することができる。 (effect)
According to the second embodiment described above, the following effects are obtained.
(1) The display device 10 displays one original blur image 173 in which the clockwise image unit 173b and the counterclockwise image unit 173c located in the counterclockwise direction Ucw from the clockwise image unit 173b are combined. A ROM 52 is provided as an example of a storage unit for storing. When the pointer image 80 rotates in the clockwise direction Cw, the control unit 55 sets the brightness of the clockwise side image unit 173b in the original blur image 173 to be lower than that of the counterclockwise side image unit 173c, thereby rotating clockwise. When the blur pointer image 73Cw is generated and the pointer image 80 rotates in the counterclockwise direction Ucw, the brightness of the counterclockwise image portion 173c in the original blur image 173 is set lower than that of the clockwise image portion 173b. As a result, a counterclockwise blur pointer image 73Ucw is generated.
A clockwise blur pointer image 73Cw and a counterclockwise blur pointer image 73Ucw can be generated simply by adjusting the brightness of the clockwise side image portion 173b and the brightness of the counterclockwise side image portion 173c in one original blur image 173. It becomes. Therefore, it is not necessary to prepare two original blur images, and the amount of image data stored in the ROM 52 of the microcomputer 50 can be reduced.
Further, since both the clockwise side image unit 73b and the counterclockwise side image unit 73c are displayed, the boundary between the clockwise side image unit 73b and the counterclockwise side image unit 73c becomes inconspicuous, and the blur is less uncomfortable. The pointer image 73 can be displayed.

　（第３の実施形態）
　本発明に係る表示装置の第３の実施形態について、図面を参照して説明する。以下、第２の実施形態との相違点を中心に説明する。
　図１１に示すように、本実施形態におけるブラー指針画像７４はくり抜き部を有しない。よって、ブラー指針画像７４は指針画像８０と重なる重複領域Ｇを有する。 (Third Embodiment)
A third embodiment of the display device according to the present invention will be described with reference to the drawings. Hereinafter, the differences from the second embodiment will be mainly described.
As shown in FIG. 11, the blur pointer image 74 in this embodiment does not have a hollow portion. Therefore, the blur pointer image 74 has an overlapping region G that overlaps with the pointer image 80.

　図９（ａ）及び図１０（ａ）は指針画像８０の幅方向における指針画像８０の明度を示すグラフであり、図９（ｂ）及び図１０（ｂ）は指針画像８０の幅方向におけるブラー指針画像７４の明度を示すグラフであり、図９（ｃ）及び図１０（ｃ）は指針画像８０の明度とブラー指針画像７４の明度を足し合わせた明度を示すグラフである。 9 (a) and 10 (a) are graphs showing the brightness of the pointer image 80 in the width direction of the pointer image 80, and FIGS. 9 (b) and 10 (b) are blurs in the width direction of the pointer image 80. 9 (c) and 10 (c) are graphs showing the brightness of the pointer image 74, which is the sum of the brightness of the pointer image 80 and the brightness of the blur pointer image 74.

　ブラー指針画像７４と指針画像８０が重なる重複領域Ｇにおいては、比較例である図９（ｃ）に示す足し合わせた明度は、図９（ａ）に示すブラー指針画像７４を重ねる前の指針画像８０の明度よりも高くなる。よって、比較例では、指針画像８０にブラー指針画像７４が重ねられた場合、重複領域Ｇの明度が高まり、重複領域Ｇが発光して見えるため、視認者に違和感を与えていた。
　この点、本実施形態では、制御部５５は、ブラー指針画像７４を指針画像８０に重ねて表示する際、図１０（ａ）に示すように、重複領域Ｇにおける指針画像８０の明度を低下させつつ、図１０（ｂ）に示すように、重複領域Ｇにおけるブラー指針画像７４の明度を低下させる。これにより、図１０（ｃ）に示すように、重複領域Ｇにおける足し合わせた明度が図９（ａ）に示すブラー指針画像７４を重ねる前の指針画像８０の明度と同等になる。この同等は、±３％の差分を含むものとする。これにより、指針画像８０にブラー指針画像７４が重ねて表示された場合に重複領域Ｇが発光して見えることが抑制され、視認者に違和感を与えることが抑制される。
　なお、重複領域Ｇにおけるブラー指針画像７４の明度の低下割合と重複領域Ｇにおける指針画像８０の明度の低下割合の比率は適宜調整可能である。 In the overlapping region G where the blur pointer image 74 and the pointer image 80 overlap, the added brightness shown in FIG. 9 (c), which is a comparative example, is the pointer image before overlapping the blur pointer image 74 shown in FIG. 9 (a). It will be higher than the brightness of 80. Therefore, in the comparative example, when the blur pointer image 74 is superimposed on the pointer image 80, the brightness of the overlapping region G is increased and the overlapping region G appears to emit light, which gives the viewer a sense of discomfort.
In this respect, in the present embodiment, when the blur pointer image 74 is superimposed on the pointer image 80 and displayed, the control unit 55 reduces the brightness of the pointer image 80 in the overlapping region G as shown in FIG. 10A. At the same time, as shown in FIG. 10B, the brightness of the blur pointer image 74 in the overlapping region G is reduced. As a result, as shown in FIG. 10 (c), the added brightness in the overlapping region G becomes the same as the brightness of the pointer image 80 before the blur pointer image 74 shown in FIG. 9 (a) is superimposed. This equivalence shall include a difference of ± 3%. As a result, when the blur pointer image 74 is superimposed on the pointer image 80, it is suppressed that the overlapping region G is emitted and appears, and it is suppressed that the viewer feels uncomfortable.
The ratio of the reduction rate of the brightness of the blur pointer image 74 in the overlapping region G and the reduction ratio of the brightness of the pointer image 80 in the overlapping region G can be appropriately adjusted.

　（効果）
　以上、説明した第３の実施形態によれば、以下の効果を奏する。
　（１）ブラー指針画像７４は指針画像８０と重なるように表示される。ブラー指針画像７４と指針画像８０が重なる重複領域Ｇの明度は、ブラー指針画像７４を重ねる前の指針画像８０の明度と同等となるように、重複領域Ｇにおけるブラー指針画像７４の明度と重複領域Ｇにおける指針画像８０の明度が設定される。
　この構成によれば、ブラー指針画像７４が指針画像８０に重なったときに重複領域Ｇが発光して見えることが抑制される。 (effect)
According to the third embodiment described above, the following effects are obtained.
(1) The blur pointer image 74 is displayed so as to overlap the pointer image 80. The brightness of the overlapping region G where the blur pointer image 74 and the pointer image 80 overlap is equal to the brightness of the pointer image 80 before the blur pointer image 74 is overlapped, so that the brightness of the blur pointer image 74 and the overlapping region in the overlapping region G are equal to each other. The brightness of the pointer image 80 in G is set.
According to this configuration, when the blur pointer image 74 overlaps the pointer image 80, the overlapping region G is suppressed from appearing to emit light.

　なお、本発明は以上の実施形態及び図面によって限定されるものではない。本発明の要旨を変更しない範囲で、適宜、変更（構成要素の削除も含む）を加えることが可能である。以下に、変形の一例を説明する。 The present invention is not limited to the above embodiments and drawings. Changes (including deletion of components) can be made as appropriate without changing the gist of the present invention. An example of the modification will be described below.

　（変形例）
　上記各実施形態においては、高速領域においてブラー指針画像６０が表示されていたが、ブラー指針画像６０が省略されてもよい。 (Modification example)
In each of the above embodiments, the blur pointer image 60 is displayed in the high-speed region, but the blur pointer image 60 may be omitted.

　上記第２の実施形態においては、１つの元ブラー画像１７３から時計回り用ブラー指針画像７３Ｃｗと反時計回り用ブラー指針画像７３Ｕｃｗが生成されていた。しかしながら、これに限らず、時計回り用ブラー指針画像７３Ｃｗと反時計回り用ブラー指針画像７３Ｕｃｗそれぞれに対応する２つの元ブラー画像が記憶されていてもよい。 In the second embodiment, the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw were generated from one original blur image 173. However, the present invention is not limited to this, and two original blur images corresponding to each of the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw may be stored.

　上記各実施形態において、ブラー指針画像７１のうち反時計回り側画像部７１ｃが省略されてもよいし、ブラー指針画像７２のうち時計回り側画像部７２ｂが省略されてもよい。すなわち、進行方向画像部が表示されていればよく、軌跡方向画像部が省略されてもよい。 In each of the above embodiments, the counterclockwise side image portion 71c of the blur pointer image 71 may be omitted, or the clockwise side image portion 72b of the blur pointer image 72 may be omitted. That is, the traveling direction image unit may be displayed, and the locus direction image unit may be omitted.

　上記各実施形態においては、表示装置１０は画像により車速を示す指針計を表示していたが、車速に限らず、エンジン回転数や残燃料を示す指針計であってもよい。また、１つの画像に複数種類の指針計が表示されていてもよい。さらに、指針計に限らず、ユーザの操作に応じて指示部の一例であるポインタが画面上を移動する表示装置であってもよい。この場合、ポインタの移動速度に応じてブラー指針画像６０，７１，７２，７３，７４と同様のブラー画像が表示される。 In each of the above embodiments, the display device 10 displayed a pointer meter indicating the vehicle speed by an image, but the display device 10 is not limited to the vehicle speed, and may be a pointer meter indicating the engine speed and the remaining fuel. Further, a plurality of types of pointers may be displayed on one image. Further, the present invention is not limited to the pointer meter, and may be a display device in which a pointer, which is an example of an indicator unit, moves on the screen according to a user operation. In this case, a blur image similar to the blur pointer images 60, 71, 72, 73, 74 is displayed according to the moving speed of the pointer.

　上記各実施形態において、制御部５５は、図示しない運転者の視線方向を検出する視線検出部の検出結果に基づき、ブラー演出の有無を切り替えてもよい。制御部５５は、視線検出部を通じて運転者の視線方向が液晶パネル２０を向いている旨判定するとブラー指針画像６０，７１，７２，７３，７４を表示することによりブラー演出を行い、視線検出部を通じて運転者の視線方向が液晶パネル２０を向いていない旨判定するとブラー指針画像６０，７１，７２，７３，７４を非表示とすることによりブラー演出を行わない。これにより、運転者が液晶パネル２０を視認していない状態での無駄なブラー演出の回数を減らすことができ、制御部５５の処理負担を減らすことができる。 In each of the above embodiments, the control unit 55 may switch the presence or absence of the blur effect based on the detection result of the line-of-sight detection unit that detects the line-of-sight direction of the driver (not shown). When the control unit 55 determines through the line-of-sight detection unit that the driver's line-of-sight direction is facing the liquid crystal panel 20, the control unit 55 displays blur pointer images 60, 71, 72, 73, 74 to perform a blur effect, and the line-of-sight detection unit When it is determined that the driver's line of sight is not facing the liquid crystal panel 20, the blur pointer images 60, 71, 72, 73, and 74 are hidden so that the blur effect is not performed. As a result, the number of unnecessary blurring effects when the driver is not visually recognizing the liquid crystal panel 20 can be reduced, and the processing load of the control unit 55 can be reduced.

　上記実施形態においては、表示部は液晶パネル２０であったが、液晶パネル２０に限らず、有機ＥＬディスプレイ（ＯＥＬＤ：Organic Electro-Luminescence Display）であってもよい。 In the above embodiment, the display unit is the liquid crystal panel 20, but the display unit is not limited to the liquid crystal panel 20, and may be an organic EL display (OELD: Organic Electro-Luminescence Display).
