iphone视图放大

It’s a common problem: Some things are just too hard to see. Usually, they’re too far away, too dark, or too small. With a feature called Magnifier, your iPhone can function as a magnifying glass and sight aid. Here’s how to use it.

这是一个常见的问题：有些东西太难看了。 通常，它们距离太远，太暗或太小。 借助放大镜功能，您的iPhone可以用作放大镜和瞄准具。 这是使用方法。

什么是放大镜？ (What Is Magnifier?)

Magnifier is an accessibility feature built into iOS 10 and up that allows you to use your iPhone’s camera as a makeshift magnifying glass or telescope. Some people with sight issues use the Camera app for a similar function, but Magnifier includes extra features designed specifically to help with sight impairments. For example, you might need help reading small text on a menu or a distant sign with confusing colors or low-contrast lettering. In those cases, Magnifier is an ideal tool.

放大镜是iOS 10及更高版本中内置的辅助功能，可让您将iPhone的相机用作临时放大镜或望远镜。 有些视力不佳的人将“相机”应用程序用于类似功能，但放大镜包含专门设计用于帮助视力障碍的额外功能。 例如，您可能需要帮助来阅读菜单上的小文本或颜色混乱或对比度低的远距离标志。 在这种情况下，放大镜是理想的工具。

如何在iPhone上启用放大镜 (How to Enable Magnifier on Your iPhone)

To use Magnifier, you must first enable it in Settings. Launch Settings by tapping on its icon, which looks like a gear. (It’s usually on the first page of your Home screen or in the Dock.)

要使用放大镜，必须首先在“设置”中启用它。 通过点击其图标，看起来像一个齿轮来启动设置。 (通常位于主屏幕的第一页或Dock中。)

In Settings, swipe down the list until you find Accessibility and tap on it.

在“设置”中，向下滑动列表，直到找到“辅助功能”，然后在其上点击。

In the Accessibility menu, tap “Magnifier.” In the Magnifier settings, tap on the Magnifier toggle switch to turn it on.

在辅助功能菜单中，点击“放大镜”。 在放大镜设置中，点击放大镜切换开关以将其打开。

After that, exit Settings by returning to the Home screen.

之后，通过返回主屏幕退出设置。

如何在iPhone上快速启动放大镜 (How to Quickly Launch Magnifier on Your iPhone)

Once Magnifier has been enabled in Settings, there are two ways to launch it: a special button combination and a Control Center shortcut.

在“设置”中启用“放大镜”后，有两种启动方法：特殊的按钮组合和“控制中心”快捷方式。

For the button combination, how you launch it depends on the type of iPhone you have.

对于按钮组合，如何启动它取决于您拥有的iPhone的类型。

• iPhones with a Home button: Push the Home button three times.

  带有“主页”按钮的iPhone：按下“主页”按钮三下。

• iPhones without a Home button: Push the side button three times.

  没有“主页”按钮的iPhone：按下侧面按钮3次。

Once you tap the proper button three times, Magnifier will appear on the screen.

一旦您单击了适当的按钮三次，放大镜将出现在屏幕上。

如何使用控制中心启动放大镜 (How to Launch Magnifier Using Control Center)

You can also launch Magnifier from Control Center if you enable its shortcut in Settings. To do so, navigate to Settings > Control Center > Customize Controls. In the “More Controls” list, locate “Magnifier” and tap on it. It will then be added to your “Include” list at the top of the page.

如果在“设置”中启用了放大镜快捷方式，也可以从“控制中心”启动放大镜。 为此，请导航至设置>控制中心>自定义控件。 在“更多控件”列表中，找到“放大镜”，然后点击它。 然后，它将被添加到页面顶部的“包含”列表中。

Once enabled, launch “Control Center” on iPhones with a Home button by swiping upward from the bottom of the screen. On iPhones without a Home button, swipe downward from the top right corner of the screen. Tap on the magnifying glass icon to launch Magnifier.

启用后，通过从屏幕底部向上滑动，使用主屏幕按钮在iPhone上启动“控制中心”。 在没有“主页”按钮的iPhone上，从屏幕右上角向下滑动。 点击放大镜图标以启动放大镜。

如何使用放大镜 (How to Use Magnifier)

Once you launch Magnifier, you will see a screen that looks very similar to Apple’s Camera app. Magnifier uses your iPhone’s built-in camera hardware to display whatever you’re pointing at on the screen. It can be used in vertical or horizontal orientation.

启动放大镜后，您将看到一个与Apple的Camera应用程序非常相似的屏幕。 放大镜使用iPhone的内置摄像头硬件在屏幕上显示您要指向的内容。 可以垂直或水平使用。

Just below the live image area, you will find a small control area. The slider at the top functions as a zoom feature, changing the size of the image. From left to right below that, you see the following controls:

在实时图像区域的下面，您会发现一个小的控制区域。 顶部的滑块用作缩放功能，可更改图像的大小。 从左到右，您将看到以下控件：

• Light button (lightning icon): This turns on your iPhone’s LED for illumination in a dark setting.

  浅色按钮(闪电图标)：这会打开iPhone的LED，以在黑暗的环境中进行照明。

• Lock focus button (padlock icon): This locks the focus on an object you have tapped on even if you move the image around.

  锁定焦点按钮(挂锁图标)：即使将图像四处移动，它也可以将焦点锁定在轻敲的对象上。

• Freeze frame button (circle): This freezes the live image so you can get a steady look at it, adjust its zoom size, and more.

  冻结帧按钮(圆圈)：冻结实时图像，以便您可以稳定观看它，调整其缩放大小等等。

• Filters button (three interlocking circles): This opens a menu that lets you adjust brightness and contrast, inverse the colors on the image, or apply color filters that can potentially aid people with color blindness or other sight impairments.

  “滤镜”按钮(三个互锁的圆圈)：这将打开一个菜单，您可以通过该菜单调整亮度和对比度，反转图像上的颜色或应用可能有助色盲或其他视力障碍人士的滤色器。

While viewing a live image, you can zoom in and out using either the pinch-to-zoom gesture or the slider bar.

在观看实时图像时，您可以使用捏合缩放手势或滑动条来放大和缩小。

And if you freeze the image using the circle button, you can zoom in and out and move the frozen image around with your fingers to get a better look at something, even if you didn’t center it perfectly the first time.

而且，如果您使用圆形按钮冻结了图像，则可以放大和缩小并用手指四处移动冻结的图像，以更好地观察某些事物，即使您第一次没有完美地将其居中。

You can also save or share the image you have frozen by holding your finger down on the image until a tiny bubble pops up with “Save Image” and “Share” options. Tap on the option you’d like to use.

您还可以通过以下方式保存或共享冻结的图像：用手指按住图像，直到弹出带有“保存图像”和“共享”选项的小气泡。 点击您要使用的选项。

If you have trouble making out some details in the live scene or an image you’ve frozen, tap on the three circles in the lower-right corner of the screen, and you’ll find an impressive array of color filter options.

如果您无法在实时场景或已冻结的图像中找出一些细节，请点击屏幕右下角的三个圆圈，您会发现令人印象深刻的滤色镜选项。

The two sliders control the brightness and contrast of the image, while the color filters change the color tone of the image. They include white/blue, yellow/blue, grayscale, yellow/black, and red/black options.

这两个滑块控制图像的亮度和对比度，而滤色器则更改图像的色调。 它们包括白色/蓝色，黄色/蓝色，灰度，黄色/黑色和红色/黑色选项。

You can also invert the colors of the image (making it a negative image) with any of the color-filter options by tapping on the button in the lower-left corner that looks like two squares with curved arrows between them.

您还可以通过单击左下角的看起来像两个正方形之间带有弯曲箭头的按钮，使用任何滤色器选项反转图像的颜色(使其成为负像)。

If you want to exit the color filters options, tap on the three circles in the lower-right corner of the screen, and you will return to the original control options.

如果要退出滤色器选项，请点击屏幕右下角的三个圆圈，您将返回到原始控制选项。

When you’re completely done with Magnifier, you can exit the utility on an iPhone with a Home button by pushing the Home button once. On iPhones without a Home button, slide your finger upward from the bottom of the screen until the Home screen appears.

放大镜完全用完后，您可以通过按一次“主页”按钮退出带有“主页”按钮的iPhone上的实用程序。 在没有“主页”按钮的iPhone上，从屏幕底部向上滑动手指，直到出现“主页”屏幕。

Best of all, you can return to Magnifier quickly any time you need (as long as it’s enabled), by either using the button combination or invoking Control Center. Magnifier even works in the lock screen. It’s just one more iPhone accessibility feature that can make life easier for everyone.

最重要的是，您可以通过使用按钮组合或调用控制中心，在需要的任何时间(只要启用)快速返回到放大镜。 放大镜甚至可以在锁定屏幕中使用。 这只是iPhone的另一项辅助功能，可以使每个人的生活更加轻松。
