then I'm texting from Andrew authority now feature you finding the camera of many high-end smartphones is optical image stabilization but the question is what is it and how does it work well let me explain normally when you take a photograph you maybe sort of line up the shot with you your subject and you maybe you'll play with the some of the controls you'll do the focusing and then at some point you'll hit the button to take the photo now when you do that what happens is a shutter opens particularly traditional camera and light will come in and it will hit the sensor in the old days I hit a film and the exposure would occur during that moment now if you move the camera even because your hands are slightly shaking because you can't keep your hand it's rock solid still all the time even if you move the camera a little bit you get blurriness now blurriness of course is the enemy of a good photo and therefore there's a system called optical image stabilization and what that does is this is whenever you move in one direction little mechanism works inside to bring the lens in the other direction therefore compensate for the movement this normally happens on two axes in fact what happens is there are cup of gyroscopes that actually measure the velocity and the angle of which way the phone is moving and as you take the picture the little microcontroller that moves are floating lens with some motors attached to it in the other other direction to compensate for that movement now obviously it can't compensate for huge movement because you only got a little lens or a little bit of movement however it can compensate for camera shake now it's also worth mentioning at this point that OAS can't stop the blurriness in a moving target for trying to photograph a pet or a child or a moving car that's going past you at speed if you're not paling correctly with it then OAS cannot compensate for the blurriness that will come from a moving object it can only compensate for what happening in your hand where you're taking the photo now of course in good light situations with a traditional camera and with a smartphone camera what happens is that shutter speed that shutter speed is very quick the time it takes to open and close that shutter to take the picture to make the exposure is very quick and therefore the amount of time which you can move is also very small however it in lower light situations maybe you're out for an evening and you're trying to take some photographs then because it's lower light you actually find the exposure time is longer and the longer it is therefore your hand can move now another type of image stabilization is called digital image stabilization and it's often used when you're recording video and sometimes it's called a video distort image stabilization and you'll find that one certain smartphone for example on the galaxy note5 now when you start videoing what happens is another computer on board shifts the picture around digitally inside of its memory to compensate for the movements that are happening with the hand and as a result you get a much more steady picture so I'd like to show you the difference between a phone that has image stabilization and a phone that doesn't and this isn't meant to be a head-to-head between two particular devices but rather just a demonstration of the quality of pictures taken with one and with the other now to do this I've got two phones with me one is the Nexus 6p and the other is the note 5 now the note 5 has optical image stabilization and the Nexus 6p does not now trying to find a way that was consistent in terms of the movement of the phone was actually quite difficult and after a lot of experimentation I found that the way that gives the most consistent results is for me to jump up in the air take a photo while I'm in the air but of course moving and then land again then do it again and do it several times and I took a whole series of photos to make sure it wasn't maybe a fluke or just the you know the very arc of my jumping like that to try and get the best comparison between those two devices so first of all here are some photos I took with the Nexus 6p which does not have image stabilization - still smokin and now here are the photos I took with a note 5 which does have image stabilization isn't you wanna stay allowed now first of all I want to say that both phones actually have very good cameras however in this situation where I'm actually jumping in the air and then taking the photo I'm actually moving while I'm taking the photo we can clearly see a difference some of the Nexus 6p photos are actually quite good and actually are pretty reasonably sharp however the majority of them are blurred on the other hand the Nick note 5 pictures one or two of them are blurred but the majority of them are quite clear and here we can see the difference between the image stabilization at work and a phone without the image stabilization what my name is Gary Sims from Andhra Authority and I hope you enjoyed this video if you did please do give it a thumbs up also please use the comments below to tell me what you think about optical image stabilization and it successes or failures you've had with it is it something you look for when you buy your next smartphone also don't forget to subscribe to Andrew or ities YouTube channel you can also follow me on social media and also if you use this link here you can talk to me in the Andhra thority forums there's a place there where you can ask me questions about optical image stabilization or about any of the topics that I cover and I will check that regularly and get back to you to see if I can help and also let's forget to stay tuned to Andrew or thority calm because we are your source for all things Android
