不久前，模糊的手机相机照片(blurry phone camera photos)是任何人都希望得到的最好结果。今天，每个人都希望获得能够与专用数码相机拍摄的质量相媲美的水晶般清晰的照片。
您可能会为手机突然生成的模糊照片而摸不着头脑，或者您只是无法在取景器中正确对焦，然后再拍下您的猫在社交媒体上做一些有趣的事情。尝试其中一些故障排除技巧来解决问题。
1.清洁你的相机镜头
脏相机镜头是手机上照片模糊的最明显罪魁祸首。涂抹在镜头上的污垢不仅会直接导致模糊或失真，还会干扰手机的自动对焦功能。
使用干净的超细纤维(microfiber)布擦拭相机镜头或眼镜，擦拭镜头。请勿在镜头或布上喷洒任何清洁剂，因为手机的外置摄像头镜头玻璃可能有一层对某些化学物质反应不佳的涂层。
如果您有防水手机，您可能需要用少量干净的淡水轻轻冲洗外层相机镜头玻璃，以去除小沙粒等矿物质碎屑。尽管现代的外置相机镜头玻璃是由蓝宝石等坚韧的硬质材料制成的，但夹在布料和玻璃之间的硬质矿物质仍然会划伤它。
2.使用正确的模式
您的相机应用程序可能有许多不同的拍摄模式。如果您不小心激活了肖像(Portrait)或微距模式(Macro Mode)等特殊模式，则可能无法让您的主体在正常拍摄时对焦。或者，当您的拍摄对象离相机太近而无法对焦时，您可能需要打开其中一种模式，例如微距模式。
3.取下保护膜(Protective Film)或屏幕保护膜(Screen Protector Off)
让我们从听起来有点傻的东西开始，但如果您在应用程序的取景器中看到稍微模糊的图像，则可能是您的屏幕上有东西扭曲了图像。
如果您刚刚从包装盒中取出一部新手机，请确保您没有将保护膜留在屏幕上。仔细阅读快速入门指南，因为某些手机（如三星 Galaxy S21 Ultra(Samsung Galaxy S21 Ultra)）具有工厂应用的屏幕保护膜，除非损坏，否则不应移除。
一些屏幕保护膜会对显示器的清晰度产生负面影响，使一切看起来都很模糊。您可以通过打开非相机应用程序并检查文本等屏幕元素来轻松检查这一点。如果屏幕上的所有内容都显得有些柔和，请考虑取下屏幕保护膜或更换为具有更好清晰度等级的屏幕保护膜。
4.清洁你的屏幕
用干净的超细纤维布擦拭手机，以排除屏幕上的油膜使图像模糊。
5. 检查镜头是否有凝结
如果您的手机暴露在水或高湿度环境中，可能会导致镜头和外置摄像头玻璃之间结露。虽然相机可能被密封以防止液体进入，但它仍然需要让空气通过以平衡相机组件内部的压力与外部大气。这就是为什么如果您在更接近亚马逊(Amazon)丛林而不是舒适湿度的条件下使用手机，液体会凝结在玻璃内部。
如果您看到相机内部有冷凝水，您唯一能做的就是等待它蒸发。将手机保持在室温和正常湿度下以加快此过程。如果问题没有消失或继续出现，则您的手机可能已遭受水损坏，您需要让专业人士对其进行评估。
6.取下你的手机壳
大多数手机壳都有足够的切口用于手机上的摄像头，但有些型号可能重叠过多，尤其是当您使用手机上的广角摄像头时。对于使用特殊传感器来测量对焦距离的手机，即使没有遮挡任何镜头的一部分，外壳也可能会部分遮挡该传感器。
虽然这不太可能，但如果您怀疑您的情况是问题所在，那么迅速将其取下并拍摄几张测试照片以排除这种可能性是一个好主意。
7.点击焦点
有时手机上的自动对焦功能会出错。在大多数情况下，您可以通过在相机应用程序取景器中点击要对焦的主题来纠正此问题。
在 iPhone 相机应用程序中，您可以点击画面中的任意位置来转移焦点，但由于Android手机相机应用程序没有标准化，确切的焦点调整方法可能因手机品牌而异。如果在您的Android(Android)手机上点击对焦似乎不起作用，请参阅相机应用程序的帮助文件以获取说明。
8.切换到不同的相机
大多数现代智能手机都配备了多个独立的摄像头。如果您的图像模糊，请尝试切换到焦距更合适的相机。即使您使用正确的相机拍摄您想要拍摄的照片，有时切换到不同的相机然后切换回来也可以重置导致问题的任何临时故障。主摄像头通常是清晰度最高的摄像头，这要归功于其更高百万像素的图像传感器。
如果您所有的后置摄像头都模糊不清或在它们之间切换不能解决问题，您也可以尝试切换到自拍摄像头，然后再切换回后置摄像头。我们已经看到一些用户报告说这对他们有帮助。
9.使用手动模式
默认情况下，您的相机应用程序大部分是自动化的。它会尝试为您选择最佳对焦和曝光设置，因此如果您正在拍摄自动对焦功能无法正确处理的主题，您只需担心构图和拍摄时间。
一些安卓(Android)手机相机应用程序带有手动或“专业(Pro)”模式，使其更像是操作单反(DSLR)相机。例如，在三星 Galaxy(Samsung Galaxy)手机上，您可以选择专业(Pro)模式并使用屏幕对焦轮手动设置相机。
虽然值得查看我们的相机设置指南(camera settings guide)，但您可以在手动模式下执行一些快速而肮脏的操作，以消除模糊和模糊：
- 使用快速快门速度，这有助于减少运动模糊。
- 调整低光场景的ISO。
许多手动模式都有一个视觉对焦指南，图像中对焦的部分将以一种颜色突出显示，这样您就知道正确的东西是对焦的。
10.尝试第三方相机应用
不幸的是，对于 iPhone 用户来说，Apple的默认应用程序不包括类似的手动模式，某些品牌的(Apple)Android手机也不包括。您最好的选择是使用第三方相机应用程序来解锁对相机的手动控制。
在 iPhone 上，我们建议使用ProCamera，虽然它有点贵，为 15 美元。Camera+是一个不错的选择，价格几乎只有一半。如果您使用的是Android 设备(Android)，我们认为最好的选择是售价 4.99 美元的Camera FV-5。部分Android手机无法很好地配合此应用，因此要么在Google Play的退款窗口内测试它，要么先尝试FV-5 Lite应用，但有许多Android 相机应用(Android camera apps)可供选择。
11.强制关闭(Force Close)应用(App)程序或重启(Restart Your)手机
智能手机(Smartphone)相机应用程序不如您在专用相机中找到的固件可靠。毕竟，智能手机上运行的进程太多了，软件bug不断被引入或发现。如果您的相机应用程序不专注于任何事情，则可能只是该应用程序的暂时问题。
首先要做的是强制关闭应用程序。在 iOS 中，从屏幕底部向上滑动到中间，调出应用轮播。向左(Swipe)或向右滑动，直到看到您的相机应用程序，然后向上滑动以关闭。
在Android上，按下最左侧的Android系统按钮（三个垂直线），它将调出应用轮播。向左(Swipe)或向右滑动以找到相机应用程序，然后将其向上滑动并从屏幕上滑出以将其关闭。
如果关闭并重新打开应用程序不起作用，请完全重启手机并重试。
12. 检查相机应用程序更新
如果您的相机对焦问题是由错误引起的，则值得检查是否有可供下载的应用程序的更新版本。相机(Camera)应用程序更新可以作为单独更新或作为主要操作系统更新的一部分进行。
如果您的相机适用于第三方应用程序但不适用于标准应用程序，则这种情况尤其可能发生，因为这表明您的相机在物理上没有任何问题。
13.将手机拍在手掌上(Phone Against Your Palm)
最后一个提示可能看起来有点奇怪，但是将手机拍在手掌上可以解决一些相机问题。这是因为相机组件具有微小的移动部件，这些部件可能会卡在特定位置，从而阻止相机转移焦点。
激活相机后，将手机背面牢固而小心地拍在掌心上。运气好的话，这会将机电组件重置到正确的位置。
14. 发送您的手机进行评估
如果您已经尝试了此列表中的所有内容，但仍然只得到模糊的图片，那么可能是时候对手机的摄像头进行专业检查了，因为模块本身可能需要更换。
Is Your Phone Camera Blurry? Try These 14 Fixes
Not too lоng ago, blurry phone camera photos were the best anyone could hope for. Today, everyone expects crystal-clear shots that rival the quality of those taken by a dedicated digital camera.
You may be scratching your head at the blurry pics your phone is suddenly producing, or you just can’t get the focus to work right in the viewfinder before you snap a picture of your cat doing something hilarious for social media. Try a few of these troubleshooting tips to clear up the issue.
1. Clean Your Camera Lens
A dirty camera lens is the most obvious culprit for blurry photos on a phone. Not only can dirt smeared on the lens cause blur or distortion directly, but it can also interfere with the autofocus feature of your phone.
Use a clean microfiber cloth for camera lenses or eyeglasses to wipe your lenses. Do not spray any cleaning agent on the lens or cloth since your phone’s outer camera lens glass may have a coating that reacts poorly to certain chemicals.
If you have a water-resistant phone, you may want to gently rinse the outer camera lens glass with a small amount of clean, fresh water to remove mineral debris such as small sand particles. Although modern outer camera lens glass is made from tough, hard materials such as sapphire, hard minerals trapped between your cloth and the glass can still scratch it.
2. Use the Correct Mode
Your camera app likely has many different shooting modes. If you’ve accidentally activated a special mode such as Portrait or Macro Mode, it might be impossible to get your subject in focus for a normal shot. Alternatively, you might need to turn on one of these modes, such as macro mode, when your subject is too close up to the camera to be in focus.
3. Take the Protective Film or Screen Protector Off
Let’s start with something that might sound a little silly, but if you’re seeing a slightly fuzzy image in the viewfinder of your app, it might be that you have something on your screen that’s distorting the image.
If you’ve just taken a new phone out of the box, ensure you haven’t left the protective film on the screen. Carefully read the quick-start guide since some phones (like the Samsung Galaxy S21 Ultra) have a factory-applied screen protector that should not be removed unless damaged.
Some screen protectors negatively affect the clarity of your display, making everything appear fuzzy. You can easily check for this by opening a non-camera app and inspecting screen elements such as text. If everything on the screen appears slightly soft, consider taking the screen protector off or replacing it with one that has a better clarity rating.
4. Clean Your Screen
Give the phone a good wipe with a clean microfiber cloth to rule out a film of grease on your screen making the image fuzzy.
5. Check the Lens For Condensation
If your phone has been exposed to water or high humidity, this may lead to condensation between the lens and outer camera glass. Although the camera may be sealed against liquid ingress, it still needs to let air through to equalize the pressure inside the camera assembly with the outside atmosphere. This is why liquid can condensate onto the inside of the glass if you’re using the phone in conditions closer to the Amazon jungle than comfortable humidity.
If you see condensation inside the camera, the only thing you can do is wait for it to evaporate. Keep the phone at room temperature and at normal humidity to speed up this process. If the problem doesn’t go away or keeps returning, your phone may have suffered water damage, and you’ll need to have a professional evaluate it.
6. Take Off Your Phone Case
Most phone cases have ample cutouts for the cameras on your phone, but some models may have too much overlap, especially when you use the widest-angle camera on your phone. For phones that use special sensors to measure distance for focus, the case may partly obscure that sensor even if it doesn’t obscure part of any lens.
While it’s not likely, if you suspect your case is the issue, quickly taking it off and shooting a few test photos to rule out the possibility is a good idea.
7. Tap For Focus
Sometimes the autofocus feature on your phone gets things wrong. In most cases, you can rectify this by tapping on the subject you want to focus on in the camera app viewfinder.
On the iPhone camera app, you can tap anywhere in the frame to shift focus, but since Android phone camera apps aren’t standardized, the exact focus adjustment method may differ from one brand of phone to the next. If tapping to focus doesn’t seem to work on your Android phone, consult the camera app’s help file for instructions.
8. Switch to a Different Camera
Most modern smartphones are equipped with multiple independent cameras. If your image is blurry, try switching to a camera with a more appropriate focal length. Even if you are on the right camera for the shot you want to take, sometimes switching to a different camera and then switching back can reset whatever temporary glitch is causing issues. The main camera is usually the one with the best clarity, thanks to its higher megapixel count image sensor.
If all of your back cameras are blurry or switching between them doesn’t fix the one that’s a problem, you can also try switching to the selfie camera and then back to the rear cameras. We’ve seen some users report that this helped them.
9. Use Manual Mode
By default, your camera app is mostly automated. It tries to select the best focus and exposure settings for you, so you only have to worry about framing and timing your shot if you’re taking a photo of a subject that the autofocus feature can’t handle properly.
Some Android phone camera apps come with a manual or “Pro” mode, making it more like operating a DSLR camera. For example, on a Samsung Galaxy phone, you can select Pro mode and manually your camera settings using the on-screen focus wheel.
While it’s worth checking out our camera settings guide, here are some quick and dirty thing you can do in manual mode to eliminate blur and fuzz:
- Use a fast shutter speed, which helps reduce motion blur.
- Adjust the ISO for low light scenes.
Many manual modes have a visual focus guide, where the parts of the image that are in focus will be highlighted in a color so you know that the right things are in focus.
10. Try a Third-party Camera App
Unfortunately for iPhone users, the default app from Apple does not include a similar manual mode, nor do some brands of Android phone. Your best option is to use a third-party camera app that unlocks manual control of your cameras.
On the iPhone, we suggest ProCamera, although it is somewhat pricey at $15. Camera+ is a good alternative at nearly half the price. If you’re on Android, the best choice in our opinion is Camera FV-5 for $4.99. Some Android phones don’t work well with this app, so either test it within the refund window on Google Play or try the FV-5 Lite app first, but there are many Android camera apps to choose from.
11. Force Close The App or Restart Your Phone
Smartphone camera apps aren’t quite as reliable as the firmware you’ll find in a dedicated camera. After all, there are so many running processes on a smartphone, and software bugs are constantly introduced or discovered. If your camera app just doesn’t focus on anything, it might just be a temporary problem with the app.
The first thing to do is force close the app. In iOS, swipe up from the bottom of the screen to the middle, bringing up the app carousel. Swipe left or right until you see your camera app, then swipe it upwards to close.
On Android, press the Android system button on the far left (three vertical lines), and it will bring up the app carousel. Swipe left or right to find the camera app, and swipe it up and off the screen to close it.
If closing and reopening the app doesn’t work, restart your phone completely and try again.
12. Check for Camera App Updates
If your camera focus issues are caused by a bug, it’s worth checking if there’s an updated version of the app available for download. Camera app updates can happen either as an individual update or as part of a major operating system update.
This is especially likely if your camera works well with a third-party app but not with the standard app since it suggests that there’s nothing physically wrong with your camera.
13. Slap Your Phone Against Your Palm
This last tip may seem a little strange, but slapping your phone against your palm can fix some camera problems. This is because the camera assembly has tiny moving parts that can get stuck in a particular position, stopping the camera from shifting focus.
With your camera activated, firmly yet carefully slap the back of your phone against the heel of your palm. With any luck, this will reset the electromechanical components to their correct positions.
14. Send Your Phone for Assessment
If you’ve tried everything on this list and you’re still getting nothing but blurry pictures, it may be time to have a professional look at your phone’s camera since the module itself may need replacement.
