What is Google Camera Lens Blur? How can I use it?

The Google Camera application in lens blur mode allows simulating the depth of field (bokeh effect) from SLR cameras using a smartphone or tablet:
The subject appears sharp and the background is blurred.
The Google app requires a recent smartphone or tablet under Android 4.4.2 (kitekat) or higher.

From Lens Blur to 3D, how does it work?

A lens blur JPEG image file produced by Google Camera actually includes 3 images:
  • The original image
  • A depth map
  • The final "lens blur" image

Using the depth map, our application produces 3D effects, starting from the original image or the blurred image.

Warning: Do not attempt to edit a jpeg file produced by Google Camera lens blur! This would edit the "Lens Blur" image only and the original image and depth map would be lost.
