ImageCapture: takePhoto() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The takePhoto() method of the ImageCapture interface takes a single exposure using the video capture device sourcing a MediaStreamTrack and returns a Promise that resolves with a Blob containing the data.

Syntax

js

takePhoto()
takePhoto(photoSettings)

Parameters

photoSettings Optional

An object that sets options for the photo to be taken. The available options are:

fillLightMode

The flash setting of the capture device, one of "auto", "off", or "flash".

imageHeight

The desired image height as an integer. The user agent selects the closest height value to this setting if it only supports discrete heights.

imageWidth

The desired image width as an integer. The user agent selects the closest width value to this setting if it only supports discrete widths.

redEyeReduction

A boolean indicating whether the red-eye reduction should be used if it is available.

Return value

A Promise that resolves with a Blob.

Examples

This example is extracted from this Simple Image Capture demo. It shows how to use the Promise returned by takePhoto() to copy the returned Blob to an <img> element. For simplicity it does not show how to instantiate the ImageCapture object.

js

let takePhotoButton = document.querySelector("button#takePhoto");
let canvas = document.querySelector("canvas");

takePhotoButton.onclick = takePhoto;

function takePhoto() {
  imageCapture
    .takePhoto()
    .then((blob) => {
      console.log("Took photo:", blob);
      img.classList.remove("hidden");
      img.src = URL.createObjectURL(blob);
    })
    .catch((error) => {
      console.error("takePhoto() error: ", error);
    });
}
