的放大镜。(Magnifier)
访问放大镜
您可以通过多种方式打开放大镜(Magnifier)，作为辅助功能(Accessibility)快捷方式或从控制中心(Control Center)。这是确保为每个设置设置的方法。
使用辅助功能快捷方式
如果您想通过三次单击侧边按钮或主页(Home)按钮（取决于您的设备）快速打开(depending on your device)放大镜(Magnifier)，请按照以下步骤启用它。
- 打开设置(Settings)应用程序并选择辅助功能(Accessibility)。
- 向下移动(Move)到General的最后一部分，然后选择Accessibility Shortcut。
- 选择放大镜(Select Magnifier)以在其旁边打勾。
当您三次单击按钮时，放大镜(Magnifier)应用程序将立即打开。如果您为“辅助功能快捷方式(Accessibility Shortcut)”设置了多个项目，您将看到一个弹出框以选择您想要的项目。
使用控制中心
放大镜(Magnifier)的另一个方便的地方是您的控制中心(your Control Center)。这使您可以通过简单的滑动和点击打开该工具。
- 打开设置(Settings)应用程序并选择控制中心(Control Center)。
- 向下移动到更多控件部分，然后点击(Move)放大镜(Magnifier)旁边的加号。
- 当它被添加到顶部时，包括控件(Included Controls)，拖动它以将其弹出到列表中您想要的位置。
然后，只需打开您的控制中心(Control Center)并点击放大镜(Magnifier)图标即可将其打开。
使用放大镜放大
当您准备好使用放大镜(Magnifier)时，从上述位置之一打开它。该工具使用您的设备摄像头来捕捉您正在查看的对象。
使用缩放(Zoom)滑块，点击加号和减号按钮，或在屏幕上捏合手指以增加或减少(increase or decrease the magnification)对象的放大倍率。
调整亮度
要使屏幕变亮，请点击亮度(Brightness)图标。然后，拖动滑块或使用加号和减号来增加或减少亮度。
改变对比度
除了调整亮度，您还可以更改对比度。点击对比度(Contrast)图标并使用滑块或加号和减号来增加对比度以获得更清晰的视图或减少以减少对比度。
应用过滤器
如果您有色觉缺陷(color vision deficiency)，应用滤镜可能会有所帮助。点击过滤器(Filter)图标并向右滑动以查看选项。即使你的色觉很好，使用滤镜也可以让一些东西变得更好。
您可以从灰度、黑底红、黑底黄、蓝底黄、蓝底白、反转、反转灰度、红底黑、黄底黑、黄底蓝和白底蓝中选择。
当您登陆您想要的过滤器时，您的屏幕会立即更新。您还可以选择要显示的滤色器，我们将在下面的“自定义(Customize)放大镜(Magnifier)控件(Controls)”部分中对此进行描述。
锁定焦点
当您移动设备时，您会注意到它会尝试聚焦并重新聚焦在您正在查看的对象上。虽然这很有帮助，但也很难放大您想要的确切部分。
要将焦点锁定在您正在放大的对象上，请点击焦点锁定(Focus Lock)图标。然后，当您移动设备时，焦点将保持不变。再次点击图标以解锁焦点。
切换前后摄像头
如果您更换相机，您想要放大的物体可能会更容易捕捉。点击摄像头图标可在(Camera)前置摄像头和后置摄像头(front- and rear-facing cameras)之间切换。
添加更多光
调亮屏幕并不总是添加光线的最佳方法。点击手电筒(Flashlight)图标以使用您设备的内置手电筒(your device’s built-in flashlight)。这使您对实际对象有更多了解。
自定义放大镜(Magnifier)的控件(Controls)
您可以在使用放大镜(Magnifier)屏幕时删除上述每个控件。您还可以重新排列顺序并将最常用的顺序放在顶部。此外，您可以根据需要选择要显示
的过滤器。(Filters)
点击齿轮图标以打开自定义控件(Customize Controls)屏幕。然后，您将看到以下部分：
- 主要控制：这些出现在放大镜(Magnifier)控制框的顶部。
- 次要控件：它们直接出现在主要控件(Primary Controls)下方。
- 其他控件：这些是您不想使用的控件，但如果您以后想添加它们，它们仍然可用。
要删除控件，请点击左侧的减号，然后选择右侧的
删除。(Remove)
要添加控件，请点击左侧的加号。
要重新排列控件，请向上或向下拖动右侧的三行以将控件放置在您想要的位置。您可以在主要(Primary)和次要控制(Secondary Controls)部分之间或每个部分内随机播放它们。
要更改为放大镜(Magnifier)显示的过滤器，请点击其他控件(Controls)下方的过滤器。点击(Tap)以在您要显示的过滤器旁边放置复选标记。这允许您仅显示对您有用的过滤器。
冻结帧
如果您到达要捕获和保留的放大对象中的某个位置，请点击“冻结(Freeze)”图标。当您无法直接查看屏幕时，此功能还可以帮助您捕捉放大的图像。例如，您可能正在尝试拍摄内部计算机部件上有时太小的标签或手臂后部的碎片。
然后，您将看到您冻结的帧的图像。要冻结其他帧，请点击矩形图标，移动您的设备或对象，然后再次点击冻结(Freeze)图标，该图标将显示为加号。
点击(Tap View)矩形图标旁边的查看以查看您拍摄的图像。默认情况下，这些屏幕截图不会保存到照片应用程序中。(Photos)如果要保存或共享它们，请点击右上角的共享(Share)图标。然后选择一个选项，例如Save Image或通过(Save Image)Messages共享它。
查看完图像后，点击左上角的结束。
检测你周围的人
如果您有 iPhone 12 Pro、iPhone 12 Pro Max、iPhone 13 Pro或 iPhone 13 Pro Max，您还可以使用放大镜(Magnifier)检测附近的人。这有助于您保持安全的社交距离。
点击人物(People)图标以启用该功能。移动你的 iPhone，让你的相机捕捉到你周围的人。您的设备会通过附近其他人的声音和语音通知您。完成后，点击结束返回放大镜(Magnifier)。
有关人员检测功能的更多信息，请访问Apple 支持(Apple Support)。
iPhone 或 iPad 上的摄像头显然可用于拍摄照片或拍摄视频。但是，它也是放大对象的好方法，因此请牢记

How to Use the Magnifier on iPhone and iPad
Your iРhone and iPad havе all sorts of features for calls, texts, emails, games, apps, and everything else you do with your device. However, the Magnifier might be the best feature you’re overlooking.
This handy built-in tool lets you zoom in on anything you need a clear view of— from reading small print to threading a needle. The Magnifier also gives you features to adjust your view, apply a filter, and save photos of what you’re magnifying.
When your reading glasses are in the other room or your physical magnifying glass is lost, remember to take advantage of the Magnifier on your iPhone and iPad.
Access the Magnifier
You can open the Magnifier a couple of ways, as an Accessibility shortcut or from the Control Center. Here’s how to make sure it’s set up for each.
Use an Accessibility Shortcut
If you’d like to quickly open Magnifier by triple-clicking the side button or Home button (depending on your device), follow these steps to enable it.
- Open the Settings app and select Accessibility.
- Move down to the last section for General and pick Accessibility Shortcut.
- Select Magnifier to put a checkmark next to it.
When you triple-click your button, the Magnifier app will open right up. If you have more than one item set for your Accessibility Shortcut, you’ll see a pop-up box to pick the one you want.
Use the Control Center
Another handy spot for the Magnifier is in your Control Center. This lets you open the tool with a simple swipe and tap.
- Open the Settings app and select Control Center.
- Move down to the section for More Controls and tap the plus sign next to Magnifier.
- When it’s added to the top section, Included Controls, drag to pop it into the location you want in the list.
Then, just open your Control Center and tap the Magnifier icon to open it.
Use the Magnifier to Zoom In
When you’re ready to use the Magnifier, open it from one of the spots described above. The tool uses your device camera to capture the object you’re viewing.
Use the Zoom slider, tap the plus and minus buttons, or pinch your fingers on the screen to increase or decrease the magnification of your object.
Adjust the Brightness
To lighten your screen, tap the Brightness icon. Then, drag the slider or use the plus and minus signs to increase or decrease the brightness.
Change the Contrast
Along with adjusting the brightness, you can change the contrast. Tap the Contrast icon and use the slider or plus and minus signs to increase the contrast for a sharper view or decrease to lessen the contrast.
Apply a Filter
If you have a color vision deficiency, applying a filter might help. Tap the Filter icon and slide to the right to see the options. Even if your color vision is fine, using the filters can make some things stand out better.
You can pick from grayscale, red on black, yellow on black, yellow on blue, white on blue, inverted, inverted grayscale, black on red, black on yellow, blue on yellow, and blue on white.
When you land on the filter you want, your screen updates immediately. You can also choose which color filters to display, which we’ll describe in the Customize the Controls for the Magnifier section below.
Lock the Focus
As you move your device, you’ll notice that it attempts to focus and refocus on the object you’re viewing. While this is helpful, it can also be difficult to zoom in on the exact part you want.
To lock the focus on the object you’re magnifying, tap the Focus Lock icon. Then as you move your device, the focus will remain. Tap the icon again to unlock the focus.
Switch the Front and Rear Camera
Maybe the object you want to magnify would be easier to capture if you change cameras. Tap the Camera icon to switch between the front- and rear-facing cameras.
Add More Light
Brightening the screen isn’t always the best method for adding light. Tap the Flashlight icon to use your device’s built-in flashlight. This gives you more light on the actual object.
Customize the Controls for the Magnifier
You can remove each of the controls described above from the Magnifier screen while using it. You can also rearrange the order and place those you use most at the top. Additionally, you can choose which Filters to display if you like.
Tap the gear icon to open the Customize Controls screen. You’ll then see these sections:
- Primary Controls: These appear at the top of the control box on the Magnifier.
- Secondary Controls: These appear directly below the Primary Controls.
- Other Controls: These are controls you don’t want to use but remain available should you want to add them later.
To remove a control, tap the minus sign on the left and choose Remove on the right.
To add a control, tap the plus sign on the left.
To rearrange controls, drag the three lines on the right up or down to place the control where you want it. You can shuffle them between the Primary and Secondary Controls sections or within each section.
To change the filters that display for the Magnifier, tap Filters below Other Controls. Tap to place a checkmark next to a filter you want to display. This allows you to show only those filters that are useful to you.
Freeze the Frame
If you arrive at a spot in the object you’re magnifying that you want to capture and keep, tap the Freeze icon. This feature can also help capture a magnified image of something when you can’t directly view the screen. For example, maybe you’re trying to snap a shot of the sometimes too small label on an internal computer part or a splinter on the back of your arm.
You’ll then see an image of the frame you froze. To freeze additional frames, tap the rectangle icon, move your device or the object, and tap the Freeze icon again, which will appear as a plus sign.
Tap View next to the rectangle icon to see the images you captured. These screenshots are not saved to the Photos app by default. If you want to save or share them, tap the Share icon on the top right. Then pick an option like Save Image or share it via Messages.
When you finish reviewing the images, tap End on the top left.
Detect People Around You
If you have an iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13 Pro, or iPhone 13 Pro Max, you can also use the Magnifier to detect people near you. This helps you to maintain a safe social distance.
Tap the People icon to enable the feature. Move your iPhone so that your camera captures those around you. Your device notifies you with sounds and speech for others nearby. When you finish, tap End to return to the Magnifier.
For more on the people detection feature, head over to Apple Support.
The camera on your iPhone or iPad is obviously useful for snapping photos or capturing video. However, it’s also a great way to zoom in on objects, so keep the convenient Magnifier tool in mind!
