- a system has been proposed in which a common subject is simultaneously imaged by two left and right video cameras, and a stereoscopic image is displayed by simultaneously outputting the left and right images.
- the baseline length (baseline) between the two video cameras that is, the distance between both eyes as a stereoscopic camera is set to about 65 mm, which corresponds to the distance between human eyes regardless of the zoom ratio of the lens.
- the parallax increases in the zoomed-up video, forcing the visual system to perform information processing different from daily life, which causes visual fatigue.
- the left and right images are overlapped as they are, the images are duplicated, resulting in an unnatural image.
- the binocular positions are L and R and the points on the subject are A and B
- the angle LAR and the angle LBR are respectively defined as absolute parallaxes

- the prism uses the refraction of the optical axis and has a problem that chromatic aberration occurs because the refractive index differs for each wavelength of light.
- the optical path is bent at a place other than the region where the light becomes parallel light in the path from the optical system to the image sensor, and therefore, in the zoom operation of the photographing lens, it is linked with the zoom ratio.

That is, by adjusting the amount of light with the diaphragm, there is an effect that the distance between the optical axes of the dispersed light is changed to about 7 to 65 millimeters.
- the photographing lens includes a zoom lens that expands light from the subject, and the relative parallax between the images converted by the imaging element is controlled by the zoom lens. Also good. As a result, the relative parallax between images is controlled by the zoom lens.
- each of the plurality of imaging devices may generate a captured image from the electronic signal at a rate of 60 frames per second or more, and from the electronic signal at a rate of 230 to 250 frames per second. It is desirable to generate a captured image. This brings about the effect of eliminating blur and jerkiness due to movement. In addition, a moving subject has a sufficient time resolution and can capture accurate contour information.

It is considered that a stereoscopic effect can be felt if the base line length is a value of this level. In particular, when the shooting distance is long, it is considered that the stereoscopic effect cannot be obtained unless the baseline length is long. When the baseline length is increased, the stereoscopic effect becomes clearer when the length is about 32 [mm]. On the other hand, the background blur increases. When the base line length exceeds 65 [mm], it is considered that a miniature garden effect occurs and the image is unnatural. Therefore, it is considered that the base line length is about 7 to 65 [mm] as a range that naturally appears as a stereoscopic image.

Abstract
Description
1.第1の実施の形態(撮像装置の例)
2.第2の実施の形態(映像記録再生システムの例)
[撮像装置の構成例]
図1は、本発明の実施の形態における撮像装置の一例の上面断面図である。この撮像装置は、被写体からの入射光101を受けて左右の撮像素子171および172に結像させ、左右の映像データを生成するものである。図面における上部が被写体に向かって右方向(R)であり、下部が被写体に向かって左方向(L)である。
図3は、本発明の実施の形態による撮像装置における入射瞳115のイメージ図である。入射瞳(entrance pupil)とは、レンズを被写体側から見たときの開口絞りの像である。本発明の実施の形態による撮像装置では、絞り113の像が交換レンズ110内の位置に入射瞳115として存在する。ここで、入射瞳115に相当する円の半径をrとすると、次式が成り立つ。
2r=f/F (式1)
ただし、fは焦点距離であり、FはF値である。したがって、焦点距離を固定した場合、入射瞳115の直径2rとF値は反比例の関係にあることがわかる。
D=8r/3π (式2)
すなわち、重心間距離Dは絞り149を絞ると、それに比例して小さくなることがわかる。換言すれば、絞り149の口径を変化させることにより、得られる立体感を調整することができることになる。このような前提を確認するために行った実験の結果を以下に示す。
図4は、重心間距離Dと基線長(ベースライン)との関係を示す図である。ここでは、交換レンズ110として#Aおよび#Bの2種類のレンズについて、重心間距離の理論値と基線長の実験値とを示している。
図5は、ズームによる拡大と視差との関係を示す図である。図5(a)では、左眼位置をL、右眼位置をRとし、被写体上の点をAおよびBとしている。A点を見込んだ角LARをA点の輻輳角θAとし、B点を見込んだ角LBRをB点の輻輳角θBとすると、A点とB点の視差(相対視差)dは、次式により与えられる。
d=θB-θA
ここで、角ALBをh、角ARBをgとすると、輻輳角θAはほぼhと等しく、輻輳角θBはほぼgと等しい。したがって、次式が成り立つ。
d=g-h
d≒Dδ/(DA 2-δDA)
ここで、DA,DB>>Dより、
d≒Dδ/DA 2
が成り立つ。
g'=ng
h'=nh
となる。このとき、視差d'は、次式のように表される。
d'=θB'-θA'
=g'-h'
=n(g-h)
=nd
すなわち、n倍の拡大によりn倍の視差が生じることになる。これは、テレ端側へズームしていくと立体感が増すことを意味する。換言すれば、ズーム撮影においては、短い基線長でも適正な視差を得ることができることになる。
[映像記録再生システムの構成例]
図6は、本発明の実施の形態における映像記録再生システムの一構成例を示す図である。この映像記録再生システムは、撮像部100と、映像記録部200と、映像記憶部300と、映像再生部400と、表示部500とを備えている。
