Hi Bhavesh23,

Using the below article i have created the example.

Capture Image (Photo) from Web Camera (Webcam) using HTML5 and jQuery in ASP.Net

HTML

Home

<table border="0" cellpadding="0" cellspacing="0">
    <tr>
        <th align="center"><u>Live Camera</u></th>
        <th align="center"><u>Captured Picture</u></th>
    </tr>
    <tr>
        <td>
            <div id="webcam"></div>
        </td>
        <td>
            <img id="imgCapture" /></td>
    </tr>
    <tr>
        <td align="center">
            <input type="button" id="btnCapture" value="Capture" />
        </td>
        <td align="center">
            <input type="button" id="btnSend" value="Send" disabled="disabled" />
        </td>
    </tr>
</table>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="WebCam.js" type="text/javascript"></script>
<script type="text/javascript">
    $(function () {
        Webcam.set({
            width: 320,
            height: 240,
            image_format: 'jpeg',
            jpeg_quality: 90
        });
        Webcam.attach('#webcam');
        $("#btnCapture").click(function () {
            Webcam.snap(function (data_uri) {
                $("#imgCapture")[0].src = data_uri;
                $("#btnSend").removeAttr("disabled");
            });
        });
        $("#btnSend").click(function () {
            $.ajax({
                type: "POST",
                url: "Home.aspx/SaveCapturedImage",
                data: "{data: '" + $("#imgCapture")[0].src + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (r) {
                    window.location.href = '/Default.aspx';
                }
            });
        });
    });
</script>

Default

<table border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td align="center">
            <u>Captured Picture</u>
        </td>
    </tr>
    <tr>
        <td>
            <asp:Image ID="imgCapture" runat="server" Style="width: 320px; height: 240px" />
