体画像表示で問題となる画枠による奥行き感の歪
を低減しようとするものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a display device for stereoscopic television images, in which the brightness of the periphery of the screen, for example, is directed toward the image frame compared to the center of the screen. By gradually decreasing the presence of the image frame, it attempts to reduce the distortion of the sense of depth caused by the image frame, which is a problem in stereoscopic image display.
（従来の技術）
従来立体画像を再生するには、例えば２眼式は
第２図に示すように左右の画像を一枚の画面上に
左右視差を与えて表示し、光の偏光やレンチキユ
ラーなどを用いて、左右の眼にそれぞれの画像を
分離して見える様にする事により奥行き感を生じ
させてきた。(Prior art) Conventionally, in order to reproduce stereoscopic images, for example, a twin-lens system displays left and right images on a single screen with left and right parallax as shown in Figure 2, and uses polarization of light, lenticular, etc. has been used to create a sense of depth by allowing the left and right eyes to see separate images.
（発明が解決しようとする問題点）
第２図に示すような立体テレビジヨン画像表示
装置において、観察の対象物が画面中央部に存在

枠が二重に見え、また眼が画枠を見てしまつた場
合には対象物が二重に分離して見えるという欠点
を生じる。(Problems to be Solved by the Invention) In a stereoscopic television image display device as shown in FIG. Although you can get a sense of depth without any problems with this method,
If the object is near the left and right edges of the screen, the left and right image frames will be visible together with the object. Therefore, when the eye sees the object as a fused image, the image frame appears double, and when the eye looks at the image frame, the object appears to be separated into two parts. arise.
この事情を以下にさらに詳細に説明する。第３
図は受信者の注視点が画面の中央部にある場合
で、スクリーン上左目画像はA1、右目画像はB1
に表示され、偏光による分離などで各々左目、右
目に別々に入力される。従つて受信者がA1、B1
の像を同一の物体像と認識した場合、それはスク
リーン（距離d1）上の２つの像A1、B1と思わず、
距離d2にある１つの像C1を見ていると思つてお
り、視覚系もそのように制御される。 This situation will be explained in more detail below. Third
The figure shows the case where the recipient's gaze point is in the center of the screen, the left eye image on the screen is A 1 and the right eye image is B 1
The images are displayed on the screen, and are input separately to the left and right eyes through separation using polarization. Therefore, the recipients are A 1 , B 1
When we recognize the images of the same object, we can't help but think that they are two images A 1 and B 1 on the screen (distance d 1 ).
We think we are looking at an image C 1 at a distance d 2 , and our visual system is controlled accordingly.
第４図は像がスクリーン左端Ｅに接近した場合
で、このときには像A2，B2とともにＥの存在も
受信者に認識される。受信者がA2，B2を同一物
体と判断して距離d2に視覚系が制御されると、Ｅ

狭いので画像を観視する場合注視点を移動させな
がら見ており、通常のテレビジヨンでは受像機面
上を上下左右に移動するだけであるが、立体テレ
ビジヨンではそれに加えて奥行き方向の制御が加
わるからである。 FIG. 4 shows a case where the image approaches the left edge E of the screen, and at this time, the presence of E along with images A 2 and B 2 is recognized by the receiver. When the receiver judges A 2 and B 2 to be the same object and the visual system is controlled to a distance d 2 , E
Conversely, the left eye recognizes light from F and the right eye sees light from G, resulting in a double image. This is because in human vision, the central vision is narrow compared to the visual field, so when viewing an image, the point of gaze must be moved while viewing.In a normal television, the point of gaze is simply moved up, down, left and right on the receiver surface. This is because in 3D television, control in the depth direction is added in addition to this.

（実施例） 以下本発明の実施例について詳細に記述する。(Example) Examples of the present invention will be described in detail below.
第１図ａに本発明構成のブロツク線図を示し、
第１図ｂに画像信号に乗算すべきシエーデイング
信号を示す。水平周期信号３に同期したシエーデ
イング波形１０により、乗算器１１を制御して左
右カメラ１，２の信号レベル左右端に向う程低下
させ第１図ｃのように左右画枠の認識が困難な立
体画像を再生する。 FIG. 1a shows a block diagram of the configuration of the present invention,
FIG. 1b shows a shading signal to be multiplied by the image signal. Using the shading waveform 10 synchronized with the horizontal periodic signal 3, the multiplier 11 is controlled to reduce the signal levels of the left and right cameras 1 and 2 toward the left and right ends, thereby creating a three-dimensional image in which it is difficult to recognize the left and right image frames, as shown in Figure 1c. Play the image.
上述の実施例では画枠の明るさのレベルが低い
とき、画面左右端に向つて輝度を低下させるよう
にシエデイング補正をしたが、画枠が一定の明る
さを有する場合は、この画枠の明るさに対応する
明るさに画面の信号レベルを調整すればよい。 In the above embodiment, when the brightness level of the image frame is low, shedding correction is performed to reduce the brightness toward the left and right edges of the screen. However, when the image frame has a constant brightness, All you have to do is adjust the signal level of the screen to a brightness that corresponds to the brightness.
次に別の実施例として、表示装置の画枠が色相
と彩度を有するときは画面の中心部分より左右端
部に向つて漸次漸近させ、画面の左右端部と表示
装置の画枠とをほぼ同じ色相とほぼ同じ彩度に調
整する。 Next, as another example, when the image frame of the display device has hue and saturation, it is gradually approached from the center of the screen toward the left and right edges, so that the left and right edges of the screen and the image frame of the display device are Adjust to approximately the same hue and approximately the same saturation.
このほかに立体テレビジヨン画像表示装置の前
面に、左右端に向つてぼかしを入れた透明板を置
いても同様の効果を得ることができる。 In addition, the same effect can be obtained by placing a transparent plate with blurred edges toward the left and right ends in front of the stereoscopic television image display device.
また、送信側ではじめから画面左右端の輝度を
落して伝送してもよい。 Alternatively, the brightness of the left and right edges of the screen may be lowered from the beginning on the transmitting side before transmission.
さらに上述の輝度または色相と彩度の調整以外
に、画面周辺における解像度を低下させてもよ
い。ただし画枠の存在感を生じさせないため画面
周辺における精細度を低下させる手法は輝度に比
べむしろ副次的要因である。 Furthermore, in addition to adjusting the brightness or hue and saturation described above, the resolution around the screen may be reduced. However, the method of reducing the definition at the periphery of the screen so as not to create the presence of the image frame is a secondary factor rather than brightness.

御信号を前述のシエーデイング波形１０に加えて
左右信号を乗算器１１の個所で制御すれば、画面
周辺と画枠の明るさを一致させることができる。 Further, the reflectance of the image frame is set to a uniform value α, and the brightness L (lux) of the surrounding light is measured using a photometer. At this time, the brightness of the image frame is Lα, so by adding a control signal corresponding to Lα to the above-mentioned shading waveform 10 and controlling the left and right signals at the multiplier 11, the brightness of the periphery of the screen and the image frame can be matched. can be done.
