camera.getPicture

Takes a photo using the camera or retrieves a photo from the device's album. The image is returned as a base64 encoded String or as the URI of an image file.

navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );

Description

Function camera.getPicture opens the device's default camera application so that the user can take a picture (if [Camera](camera.html).sourceType = [Camera](camera.html).PictureSourceType.CAMERA, which is the default). Once the photo is taken, the camera application closes and your application is restored.

If [Camera](camera.html).sourceType = [Camera](camera.html).PictureSourceType.PHOTOLIBRARY or [Camera](camera.html).PictureSourceType.SAVEDPHOTOALBUM, then a photo chooser dialog is shown, from which a photo from the album can be selected.

The return value will be sent to the [cameraSuccess](parameter/cameraSuccess.html) function, in one of the following formats, depending on the [cameraOptions](parameter/cameraOptions.html) you specify:

  • A String containing the Base64 encoded photo image.
  • A String representing the image file location on local storage (default).

You can do whatever you want with the encoded image or URI, for example:

  • Render the image in an <img> tag (see example below)
  • Save the data locally (LocalStorage, Lawnchair, etc)
  • Post the data to a remote server

Note: The image quality of pictures taken using the camera on newer devices is quite good, and images from the Photo Album will not be downscaled to a lower quality, even if a quality parameter is specified. Encoding such images using Base64 has caused memory issues on many newer devices. Therefore, using FILE_URI as the 'Camera.destinationType' is highly recommended.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Windows Phone 7 and 8
  • Bada 1.2
  • webOS
  • Tizen
  • Windows 8

iOS Quirks

Including a JavaScript alert() in either of the callback functions can cause problems. Wrap the alert in a setTimeout() to allow the iOS image picker or popover to fully close before the alert is displayed:

setTimeout(function() { 
    // do your thing here!
}, 0);

Windows Phone 7 Quirks

Invoking the native camera application while your device is connected via Zune will not work, and the error callback will be triggered.

Tizen Quirks

Only 'destinationType: Camera.DestinationType.FILE_URI' and 'sourceType: Camera.PictureSourceType.PHOTOLIBRARY' are supported.

Quick Example

Take photo and retrieve Base64-encoded image:

navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
    destinationType: Camera.DestinationType.DATA_URL
 }); 

function onSuccess(imageData) {
    var image = document.getElementById('myImage');
    image.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
    alert('Failed because: ' + message);
}

Take photo and retrieve image file location:

navigator.camera.getPicture(onSuccess, onFail, { quality: 50, 
    destinationType: Camera.DestinationType.FILE_URI }); 

function onSuccess(imageURI) {
    var image = document.getElementById('myImage');
    image.src = imageURI;
}

function onFail(message) {
    alert('Failed because: ' + message);
}
