Current behavior:
running the ionic live example or code example from ionic camera docs, in both examples it takes 1-2s for the camera component to shoot and output an image.
it feels unresponsive.

Expected behavior:
an instant (as much as possible) image output like native camera.

Steps to reproduce:
take a photo using camera component

Related code:

code implementation:

takePhoto(): Observable<Photo> {
  const getPhotoOptions: ImageOptions = {
     resultType: CameraResultType.Base64,
     source: CameraSource.Camera,
     quality: 100
  };
  const photo: Promise<Photo> = Camera.getPhoto(getPhotoOptions);
  return from(photo);
}

note: changing CameraResultType from Base64 to Uri did not help.

Other information:

verified on several android phones.

I'm experiencing this too. After pressing the button, there's approximately a 4s delay while the preview from the camera continues to show new video, and the captured image is from after the 4s delay - not the frame that's visible at the point you press the button.

This makes it almost totally unusable. You can't put something this bad in front of real-world users

[frozenfrank]

I also experience this issue. On my Macbook Air M1, I see the same 4 second delay after pressing the button before the image actually captures. In my case, I was trying to take a picture of my roommate, but by the time it actually captured and I realized he wasn't in the photo, he had already walked out the front door!

The following video was originally addressed to our developer who implemented the platform, but I now understand that it actually applies to this space: https://watch.oneclickapp.com/v/6J2JGR

[nicolidin]

I have the exact same issue, did someone found a way to fix that issue or a workaround?
Friendly ping @frozenfrank maybe you found something..

[abuksh]

anyone has any update on this ? I am having the same issues and looking for a workaround.

[gabrieldesousah]

Same issue here

[Valentindi]

Yes, i have the issue as well.

[jcham]

Same here, very slow.
Note that this seems to be a problem with Chrome and doesn't happen in Safari.

[jlorenzoC]

I'm having the same experience as @frozenfrank had on desktop browser. I haven't tested it on actual mobile device.
