например попробуйте:
<html>
<head>
<script type="text/javascript" charset="utf-8">
window.onload = function () {
var canvas = document.getElementById('canvas1');
var img = new Image();
img.src = 'http://rakstagemom.files.wordpress.com/2011/01/image-is-cumulus_clouds_panorama-from-wikipedia-commons.jpg';
var addit = -0.4;
var scrollSpeed = 0.01;
var left = 0;
var ctx = canvas.getContext('2d');
var _scale = document.documentElement.clientHeight / canvas.height;
var width = canvas.width;
var height = canvas.height;
var max = -840;
//animation loop
var init = setInterval(function() {
left += addit;
if(left > -1) {
addit = -0.4
} else if(left < max)
addit = 0.4;
//0.4
ctx.drawImage(img, left, 0, width, height);
var thisFrameTime = ( thisLoop = new Date) - lastLoop;
frameTime += (thisFrameTime - frameTime) / filterStrength;
}, scrollSpeed);
};
</script>
