　図４を参照する。図４（ａ）には、表示装置１１０及びこの表示装置１１０によって映し出された像Ｉ１’が示されている。図４（ｂ）には、表示装置１１０及びこの表示装置１１０によって映し出された像Ｉ２’が示されている。 Please refer to FIG. FIG. 4A shows a display device 110 and an image I1 'projected by the display device 110. As shown in FIG. FIG. 4 (b) shows a display 110 and an image I2 'projected by the display 110. FIG.
　表示装置１１０は、複数の画素１２１ａから構成される表示器１２０を備えている。表示器１２０から出射される光の進行方向を基準として、表示器１２０の前方には、レンズ１３２が複数配列されたレンズアレイ１３０が配置されている。レンズアレイ１３０から像Ｉ１’、Ｉ２’が結像される位置までの距離である焦点距離は、表示器１２０の光を出射する部位（画素１２１ａが発光する部位）により決まる。 The display device 110 includes a display 120 configured of a plurality of pixels 121 a. A lens array 130 in which a plurality of lenses 132 are arranged is disposed in front of the display 120 with reference to the traveling direction of the light emitted from the display 120. The focal length, which is the distance from the lens array 130 to the position where the images I1 'and I2' are formed, is determined by the portion of the display 120 where the light is emitted (the portion where the pixel 121a emits light).
　図４（ａ）を参照する。図４（ａ）には、連続する５つのレンズ１３２に対応した部位に位置する画素１２１ａが発光した状態が示されている。ここで、表示器１２０からレンズアレイ１３０までの距離をｆとする。表示器１２０から出射した光が、レンズアレイ１３０を通過し結像する場合に、レンズアレイ１３０から結像した像Ｉ１’までの距離である焦点距離Ｌ１’は、例えば、４ｆである。 Please refer to FIG. 4 (a). FIG. 4A shows a state in which the pixel 121a located at a portion corresponding to the five consecutive lenses 132 emits light. Here, the distance from the display 120 to the lens array 130 is f. When light emitted from the display 120 passes through the lens array 130 to form an image, a focal length L1 'which is a distance to the image I1' formed from the lens array 130 is, for example, 4f.
　図４（ｂ）を参照する。図４（ｂ）には、並べられたレンズ１３２のうち、一つおきに光が通過した状態が示されている。発光する画素１２１ａの間隔が広がることで、表示器１２０から出射された光の焦点距離Ｌ２’は、例えば、８ｆとなる。即ち、発光する画素１２１ａによって、焦点距離が変わり、像Ｉ２’をレンズアレイ１３０から遠い位置に投影することができる。 Refer to FIG. 4 (b). FIG. 4B shows a state in which light passes every other lens 132 aligned. The focal distance L 2 ′ of the light emitted from the display 120 is, for example, 8 f by the increase of the distance between the light emitting pixels 121 a. That is, the focal length changes depending on the light emitting pixel 121 a, and the image I 2 ′ can be projected at a position far from the lens array 130.
　上記の例では、表示装置１１０により投影される像Ｉ１’、Ｉ２’は、４ｆの倍数の位置でしか投影することができない。 In the above example, the images I1 'and I2' projected by the display device 110 can only be projected at the position of a multiple of 4f.
　表示装置を用いてより細かな表現を行おうとした場合には、表示器の画素密度を高め、このような表示器に対応させてレンズが細かく配列されたレンズアレイを用いることが考えられる。しかし、画素密度の高い表示器やレンズが細かく配列されたレンズアレイは、高価である。このため、これらの部品を用いた表示装置は、高価となる。 When it is intended to perform finer expression using a display device, it is conceivable to increase the pixel density of the display and use a lens array in which lenses are finely arranged corresponding to such a display. However, a display with high pixel density and a lens array in which lenses are finely arranged are expensive. For this reason, the display apparatus using these components becomes expensive.

It is possible to provide a display device capable of finer control of the recognized position of an image by an illusion and more detailed expression.
　請求項３に係る発明では、制御部は、光軸上の異なる位置に投影される像の彩度が異なるよう、表示器を制御している。錯覚による像の認識される位置をより細かく制御し、より細かな表現のできる表示装置を提供することができる。 In the invention according to claim 3, the control unit controls the display device so that the saturations of the images projected to different positions on the optical axis are different.

For the display 20, for example, a flat display can be used. The display 20 includes a plurality of pixel units 21 that emit light toward the lens array 30, and is controlled by the control unit 11 to emit light. The light emitted from the display 20 is a bundle of light emitted from the pixel unit 21.
　画素ユニット２１は、レンズアレイ３０に対向して複数配列されている。画素ユニット２１は、２次元配列された複数の画素２１ａによって構成されている。画素ユニット２１は、画素２１ａが発光することによって、レンズアレイ３０に向かって光を出射する。 A plurality of pixel units 21 are arranged to face the lens array 30. The pixel unit 21 is configured of a plurality of pixels 21 a arranged in a two-dimensional manner. The pixel unit 21 emits light toward the lens array 30 when the pixel 21a emits light.
　画素２１ａは、赤・緑・青の副画素により構成され、副画素が光を発することにより発光する。画素２１ａは、それぞれの副画素が発する光の組み合わせによって、明度、色相、彩度を異ならせて発光する。 The pixel 21 a is configured by red, green, and blue sub-pixels, and the sub-pixels emit light by emitting light. The pixel 21 a emits light with different lightness, hue, and saturation depending on the combination of light emitted from the respective sub-pixels.

Here, the first projected image I1 and the second projected image I2 are the same images projected on the optical axis A extending perpendicularly to the display 20. The first projected image I1 and the second projected image I2 are projected to different positions (positions of focal lengths L1 and L2) of the optical axis A, respectively.
　第１の投影像Ｉ１を投影させる場合、制御部１１は、ベース部３１に配列されているレンズ３２を通過する光が連続して隣り合うレンズ３２を通過するように画素２１ａの発光を制御する。即ち、制御部１１は、光を出射する画素ユニット２１が連続するよう画素２１ａの発光を制御する。 When projecting the first projection image I1, the control unit 11 controls the light emission of the pixel 21a so that the light passing through the lenses 32 arranged in the base unit 31 passes the adjacent lenses 32 continuously. . That is, the control unit 11 controls the light emission of the pixel 21 a so that the pixel unit 21 that emits light continues.
　第２の投影像Ｉ２を投影させる場合、制御部１１は、ベース部３１に並べられたレンズ３２のうち、一つおきに光が通過するよう画素２１ａの発光を制御する。即ち、制御部１１は、光を出射する画素ユニット２１が一つおきになるよう画素２１ａの発光を制御する。 When projecting the second projected image I2, the control unit 11 controls the light emission of the pixel 21a so that the light passes every other lens 32 arranged in the base unit 31. That is, the control unit 11 controls the light emission of the pixels 21 a such that every other pixel unit 21 emits light.
　光軸Ａは、略平行に配置された表示器２０及びレンズアレイ３０に対して、垂直に交わるように延びている、ということもできる。 The optical axis A can also be said to extend perpendicularly to the display 20 and the lens array 30 arranged substantially in parallel.
　ここで、図２には、表示装置１０が光軸Ａ上に第１の投影像Ｉ１及び第２の投影像Ｉ２を同時に投影させ、第１の投影像Ｉ１と第２の投影像Ｉ２との間（距離Ｌ３の位置）に錯覚による像Ｉ３を視認させている図が示されている。 Here, in FIG. 2, the display device 10 causes the first projected image I1 and the second projected image I2 to be simultaneously projected on the optical axis A, and the first projected image I1 and the second projected image I2 The figure which makes the image I3 by illusion visually recognize between (the position of the distance L3) is shown.
　表示装置１０は、同じ光軸Ａ上の異なる位置に、同じ像である第１の投影像Ｉ１及び第２の投影像Ｉ２が同時に投影されることにより、第１の投影像Ｉ１と第２の投影像Ｉ２との間に錯覚による像Ｉ３を視認させることができる。 The display device 10 is configured such that the first projected image I1 and the second projected image I1 are projected by simultaneously projecting the first projected image I1 and the second projected image I2 which are the same image at different positions on the same optical axis A.

　制御部１１は、光軸Ａ上の異なる位置に、それぞれ明度の異なる同じ像Ｉ１，Ｉ２を同時に投影する。このとき、制御部１１は、第２の投影像Ｉ２の明度を第１の投影像Ｉ１の明度より高くしている。すると、錯覚による像Ｉ３は、第１の投影像Ｉ１及び第２の投影像Ｉ２の真ん中よりも第２の投影像Ｉ２に近い位置に認識される（図３（ａ）参照）。逆に、制御部１１が第１の投影像Ｉ１の明度を第２の投影像Ｉ２の明度より高くすることにより、錯覚による像Ｉ３は、第１の投影像Ｉ１及び第２の投影像Ｉ２の真ん中よりも第１の投影像Ｉ１に近い位置に認識される（図３（ｂ）参照）。 The control unit 11 simultaneously projects the same images I1 and I2 different in lightness to different positions on the optical axis A. At this time, the control unit 11 makes the lightness of the second projected image I2 higher than the lightness of the first projected image I1. Then, the illusion-induced image I3 is recognized at a position closer to the second projected image I2 than to the middle of the first projected image I1 and the second projected image I2 (see FIG. 3A). Conversely, the control unit 11 causes the lightness of the first projected image I1 to be higher than the lightness of the second projected image I2, whereby the illusion-based image I3 is formed of the first projected image I1 and the second projected image I2. It is recognized at a position closer to the first projection image I1 than in the middle (see FIG. 3 (b)).

　図３（ａ）及び図３（ｂ）に示されるように、各投影像Ｉ１、Ｉ２の明度・色相・彩度を制御することにより、錯覚による像Ｉ３を各投影像Ｉ１、Ｉ２の真ん中よりも第１の投影像Ｉ１に近い位置に認識させたり（図３（ｂ）参照）、錯覚による像Ｉ３を各投影像Ｉ１、Ｉ２の真ん中よりも第２の投影像Ｉ２に近い位置に認識させたり（図３（ａ）参照）することができる。 As shown in FIGS. 3A and 3B, by controlling the lightness, hue, and saturation of each of the projected images I1 and I2, the illusion-induced image I3 is displayed from the middle of each of the projected images I1 and I2. Also, it is made to recognize at a position close to the first projection image I1 (see FIG. 3 (b)) or to make the image I3 by illusion be recognized at a position closer to the second projection image I2 than the middle of each projection image I1, I2. (See FIG. 3 (a)).
