The ImageCapture interface of the MediaStream Image Capture API provides methods to enable the capture of images or photos from a camera or other photographic device. It provides an interface for capturing images from a photographic device referenced through a valid MediaStreamTrack.


ImageCapture() Experimental

Creates a new ImageCapture object which can be used to capture still frames (photos) from a given MediaStreamTrack which represents a video stream.

Instance properties

ImageCapture.track Read only Experimental

Returns a reference to the MediaStreamTrack passed to the constructor.

Instance methods

ImageCapture.takePhoto() Experimental

Takes a single exposure using the video capture device sourcing a MediaStreamTrack and returns a Promise that resolves with a Blob containing the data.

ImageCapture.getPhotoCapabilities() Experimental

Returns a Promise that resolves with an object containing the ranges of available configuration options.

ImageCapture.getPhotoSettings() Experimental

Returns a Promise that resolves with an object containing the current photo configuration settings.

ImageCapture.grabFrame() Experimental

Takes a snapshot of the live video in a MediaStreamTrack, returning an ImageBitmap, if successful.


The following code is taken from Chrome's Grab Frame - Take Photo Sample. Since ImageCapture requires some place to capture an image from, the example below starts with a device's media device (in other words a camera).

This example shows, roughly, a MediaStreamTrack extracted from a device's MediaStream. The track is then used to create an ImageCapture object so that takePhoto() and grabFrame() can be called. Finally, it shows how to apply the results of these calls to a canvas object.

let imageCapture;

function onGetUserMediaButtonClick() {
    .getUserMedia({ video: true })
    .then((mediaStream) => {
      document.querySelector("video").srcObject = mediaStream;

      const track = mediaStream.getVideoTracks()[0];
      imageCapture = new ImageCapture(track);
    .catch((error) => console.error(error));

function onGrabFrameButtonClick() {
    .then((imageBitmap) => {
      const canvas = document.querySelector("#grabFrameCanvas");
      drawCanvas(canvas, imageBitmap);
    .catch((error) => console.error(error));

function onTakePhotoButtonClick() {
    .then((blob) => createImageBitmap(blob))
    .then((imageBitmap) => {
      const canvas = document.querySelector("#takePhotoCanvas");
      drawCanvas(canvas, imageBitmap);
    .catch((error) => console.error(error));

/* Utils */

function drawCanvas(canvas, img) {
  canvas.width = getComputedStyle(canvas).width.split("px")[0];
  canvas.height = getComputedStyle(canvas).height.split("px")[0];
  let ratio = Math.min(canvas.width / img.width, canvas.height / img.height);
  let x = (canvas.width - img.width * ratio) / 2;
  let y = (canvas.height - img.height * ratio) / 2;
  canvas.getContext("2d").clearRect(0, 0, canvas.width, canvas.height);
      img.width * ratio,
      img.height * ratio,

document.querySelector("video").addEventListener("play", () => {
  document.querySelector("#grabFrameButton").disabled = false;
  document.querySelector("#takePhotoButton").disabled = false;
