I don't know of any way to access a mobile phone's camera from the web browser without some additional mechanism (i.e. Flash or some type of container that allows access to the hardware API)

For the latter have a look at PhoneGap: <a href="http://docs.phonegap.com/phonegap_camera_camera.md.html" rel="nofollow">http://docs.phonegap.com/phonegap_camera_camera.md.html</a>

With this you should be able to access the camera at least on iOS and Android-based devices.

blocks|key|484247|text|AppMobi+HTML5+SDK曾承诺从基于html5的应用程序访问原生设备功能，包括摄像头，但不再属于谷歌所有。相反，你可以试试HTML5-based+answers+in+this+post。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|484248|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/9431475/html5-camera-access^0|1U|W|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

AppMobi HTML5 SDK once promised access to native device functionality - including the camera - from an HTML5-based app, but is no longer Google-owned. Instead, try the <a href="https://stackoverflow.com/questions/9431475/html5-camera-access">HTML5-based answers in this post</a>.

blocks|key|484314|text|在iPhone+iOS6和安卓ICS之后，HTML5有以下标签，允许你从设备上拍照：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484315|+<input+type="file"+accept="image/*"+capture="camera">|code-block|syntax|javascript|484316|Capture可以获取摄像头、摄像机和音频等值。|offset|length|style|CODE|484317|我想这个标签肯定不能在iOS5中工作，我不确定。|484318|entityMap^0|0|0|0|7|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

In iPhone iOS6 and from Android ICS onwards, HTML5 has the following tag which allows you to take pictures from your device:

<pre><code> &lt;input type="file" accept="image/*" capture="camera"&gt;
</code></pre>

<code>Capture</code> can take values like camera, camcorder and audio.

I think this tag will definitely not work in iOS5, not sure about it.

blocks|key|484362|text|好的，有一个新的HTML5特性用于访问本机设备摄像头- “getUserMedia”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484363|注意:+HTML5可以在安卓设备上处理网页上的照片捕捉(至少在最新版本上，由Honeycomb操作系统运行；但它不能在iPhones上处理，而是在iOS+6上)。|484364|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

NOTE: HTML5 can handle photo capture from a web page on Android devices (at least on the latest versions, run by the Honeycomb OS; but it can’t handle it on iPhones but iOS 6 ).

blocks|key|700226|text|如今，至少对于android来说，这是相对容易的。只需使用普通的文件输入标签，当用户点击它时，手机将询问用户是否要使用摄像头(或文件管理器等)。要上传文件，请执行以下操作。只需用相机拍照，它就会自动添加并上传。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|700227|对iphone一无所知。也许有人可以在这方面有所启发。编辑:+Iphone的工作原理与此类似。|700228|输入标记的示例：|700229|<input+type="file"+accept="image/*"+capture="camera">|code-block|syntax|javascript|700230|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|O|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|P|8|@]|9|@]|A|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Nowadays at least with android it's relatively easy. Just use normal file input tag and when user clicks it the phone will ask if user wants to use camera (or file managers etc..) to upload a file. Just take a photo with the camera and it will automatically be added and uploaded. 

No idea about iphone. Maybe someone can enlighten on that.
EDIT: Iphone works similarly.

Sample of the input tag:

<pre><code>&lt;input type="file" accept="image/*" capture="camera"&gt;
</code></pre>

Safari &amp; Chrome on iOS 6+ and Android 2.2+ support HTML Media Capture which allows you to take pictures with your device's camera or select an existing one:

<code>&lt;input type="file" accept="image/*"&gt;</code>

Here's how it works on iOS 10:

<a href="https://i.stack.imgur.com/iRcky.png" rel="noreferrer"><img src="https://i.stack.imgur.com/iRcky.png" alt="enter image description here"></a>

Android 3.0+ and Safari on iOS10.3+ also support the <code>capture</code> attribute which is used to jump straight to the camera.

<code>&lt;input type="file" accept="image/*" capture&gt;</code>

<code>capture="camera"</code> (String) and <code>accept="image/*;capture=camera"</code> (Parameter) were part of old specs and were replaced by <code>capture</code> (Boolean) the W3C Candidate Recommendation.

Just to update this, the standard now is:

<pre><code>&lt;input type="file" name="image" accept="image/*" capture="environment"&gt;
</code></pre>

to access the environment-facing (rear) camera, and 

<pre><code>&lt;input type="file" name="image" accept="image/*" capture="user"&gt;
</code></pre>

for user-facing (front) camera. To access video, substitute "video" for "image" in name.

Tested on iPhone 5c, running iOS 10.3.3, firmware 760, works fine.
