capture.captureImage

Start the camera application and return information about captured image file(s).

navigator.device.capture.captureImage(
    CaptureCB captureSuccess, CaptureErrorCB captureError, [CaptureImageOptions options]
);

Description

Starts an asynchronous operation to capture images using the device's camera application. The operation allows users to capture more than one image in a single session.

The capture operation ends either when the user closes the camera application, or the maximum number of recordings specified by [CaptureAudioOptions](captureAudioOptions.html).limit is reached. If no limit value is specified, it defaults to one (1), and the capture operation terminates after the user captures a single image.

When the capture operation finishes, it invokes the [CaptureCB](CaptureCB.html) callback with an array of [MediaFile](MediaFile.html) objects describing each captured image file. If the user terminates the operation before capturing an image, the [CaptureErrorCB](CaptureErrorCB.html) callback executes with a [CaptureError](CaptureError.html) object featuring a [CaptureError](CaptureError.html).CAPTURE_NO_MEDIA_FILES error code.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Windows Phone 7 and 8
  • Windows 8

Windows Phone 7 Quirks

Invoking the native camera application while your device is connected via Zune does not work, and the error callback executes.

Quick Example

// capture callback
var captureSuccess = function(mediaFiles) {
    var i, path, len;
    for (i = 0, len = mediaFiles.length; i < len; i += 1) {
        path = mediaFiles[i].fullPath;
        // do something interesting with the file
    }
};

// capture error callback
var captureError = function(error) {
    navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
};

// start image capture
navigator.device.capture.captureImage(captureSuccess, captureError, {limit:2});
