However, there are some cases when we can tell them apart from real images.

然而，某些情况下真假还是能区分的。

The Australian Aborigines have recorded both real and symbolic images of their time on rock walls for many thousands of years.

澳大利亚原住民已经持续数千年在石墙上记录他们所处时代现实的及非现实的画面。

Other companies are trying to craft a technological standard establishing the provenance of real images and videos.

其他公司正在尝试制定一个技术标准来确定真实图像和视频的来源。

You get maximum magnification when the real image is just barely inside the focal length of the eyepiece. .

当真实图像刚好在目镜焦距内时，您将获得最大放大倍率。

All of that was inside a box covered with LED panels that could, for example, show real images of earth from space as the backdrop.

所有这些都会在一个覆盖着 LED 面板的盒子里发生，里面的背景可以是从太空中看地球的真实景象。

Real images can be projected onto screens, because the light rays from an object are actually traveling there.

实际图像可以落在屏幕上，因为身体的光线实际上正在向它传播。

And remember, when rays converge at a point, that means a real image has been formed.

请记住，当光线在某个点相遇时， 这意味着已经形成了真实的画面。

And the image is formed by light rays that actually originated from the object, so a real image is formed.

图像是由实际来自身体的光线形成的，因此形成了真实的图像。

I shall merely lay aside the wrappings of prejudice and bad logic, and show you the real image which you possess in your soul.

我只是抛开偏见和不良逻辑的外衣， 向你展示你在灵魂中拥有的真实形象。

And when you look through a converging lens, you can see real images from objects that are beyond the focal point.

当你透过拼贴镜头看时，你可以看到离焦点更远的物体的真实图像。

Likewise, the tangent of the second angle, theta prime, is equal to the height of the real image over the focal length of the eyepiece.

同样，第二个角的正切 θ素数等于 目镜焦距上真实图像的高度。

These mirrors are convex, causing rays to converge into a real image, which is then magnified through an eyepiece or projected directly onto a digital sensor.

这些镜子是凸面的，使光线会聚 成真实图像，然后通过 目镜放大或直接投射到数字传感器上。

For instance, earlier, we talked about this technique by the name pix2pix where we could make a crude drawing of a cat and it would translate it to a real image.

举个例子，之前我们讨论过名叫 pix2pix 的技术，我们可以画一幅猫的草图，然后 pix2pix 就可以把它转换成真的照片。

The original subtended angle is the subtended angle of the unaided eye – the angle between the center of the objective lens and the height of the real image.

原对角是肉眼的对角——物镜中心与实像高度的夹角。

The object is placed just beyond the focal point of the objective lens, so light rays again form a flipped real image on the other side.

多。 物体被放置 在物镜焦点之外，因此光线再次 在另一侧形成翻转的实像。

The reason exposure control is really good is because you can manually override that exposure in order to get a photo that is more similar to the real image that you're seeing with your eyes.

曝光控制非常好的原因是因为你可以手动覆盖曝光，以获得与你用眼睛看到的真实图像更相似的照片。

And just like with telescopes, the real image is just inside the focal point of the eyepiece, generating a large virtual image for the observer to view.

就像望远镜一样，真实图像 就在目镜的焦点内，生成 一个大的虚拟图像供观察者观看。

An image is considered to be a real image if the rays from an object converge at some location, such as your eye or on some other surface, like film.

如果来自物体的光线聚焦在某个地方（例如眼睛）或另一个表面（例如胶片）上，则图像被认为是真实的。

And in a ray diagram, you can see that the tangent of the first angle, theta, is the height of the real image over the focal length of the objective lens.

在射线图中，您可以看到 第一个角度的切线 theta 是真实图像 在物镜焦距上的高度。

Did he see? Did he understand? It was as though the man's eyes were gazing into space and that he thought himself possessed by an hallucination, rather than looking upon a real image.

他看见了吗？他明白了吗？就好像这个人的眼睛在凝视着虚空，他以为自己陷入了幻觉，而不是在看一个真实的形象。
