Qualcomm chips can now adjust focus after a photo is taken thanks to Dual Image Signal Processors built into the chips. If your device has two cameras it may have the ability to focus your shots after they are taken. This would make for the fastest focus ever. No longer will you need to wait on your phone to focus on a subject prior to taking a shot. All images taken would pretty much be instant. The processors use info taken from both cameras. They translate the multiple pictures taken into depth information. This works in the same way that your brain determines depth information using your two eyes.
Features that are available with the depth information grabbed by both cameras include Fast autofocus. The Snapdragon processors set your camera’s focus quickly and accurately for an almost instant focus. ReFocus will also be available on these processors. This means you will be able to change your focus point after the shot is taken using the info collected by both cameras. You can also manipulate focus planes to cause background image blur. Some of these features have been present on phones like the HTC One M8 and the ZTE Axon Pro. Check out the video above to see how the process works.
