? call camera: navigator.mediaDevices.getUserMedia
Photo: context.drawImage (video, 0,0,480,320);
transfer base64: var img_base64 = canvas.toDataURL ("image/jpeg", 0.5);
I have this content you can come to my home page to see
navigator.getUserMedia
https://developer.mozilla.org.
write widht= "3840" height= "2160"
context.drawImage (video, 0,01920) to canvas on html;
change it to
context.drawImage (video, 0,0,3840);
put two places
{
video: true
}to
{
"video": {width: 3840, height: 2160}
}, there is another solution
<input type="file" capture="camera" accept="image/*"/> if you compress
https://developer.mozilla.org.
type pass' image/jpeg'" and then set the appropriate encoderOptions value, or modify the canvas size in the previous code
