Capturing Images from Camera with HTML5: A Quick Guide

This is a guide that explains how to use HTML5 to capture images from a camera. It provides a code snippet that uses the getUserMedia() method in combination.

To capture an image from a camera using HTML5, you can use the getUserMedia() method in combination with the <video> and <canvas> elements. Here's an example code snippet:

 <!DOCTYPE html>
	<title>Camera capture demo</title>
		<button id="capture-btn">Capture Image</button>
		<canvas id="canvas" width="640" height="480"></canvas>

		// Get the canvas and button elements
		const canvas = document.getElementById('canvas');
		const captureBtn = document.getElementById('capture-btn');

		// Get user media (i.e., camera)
		navigator.mediaDevices.getUserMedia({ video: true })
			.then(stream => {
				// Display video stream in <video> element
				const video = document.createElement('video');
				video.srcObject = stream;
				video.autoplay = true;

				// When capture button is clicked, draw current video frame on canvas
				captureBtn.addEventListener('click', () => {
					canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height);
			.catch(error => console.error('Error accessing camera:', error));

In this code, the getUserMedia() method is used to request access to the user's camera, and the resulting video stream is displayed in a <video> element. When the "Capture Image" button is clicked, the current video frame is drawn onto a <canvas> element using the drawImage() method.

You can modify this code to suit your specific needs, such as adding filters or uploading the captured image to a server.
