absolutely incredible for its size but it probably has been for about the last 10 years which raises the question what the heck is going on with pc laptops it feels like not only have they not really improved in any meaningful way but in some cases they've even gotten worse now my assumption here was that laptop makers figured webcam that's an easy place to cut costs but as it turns out that is only a small piece of the puzzle just like our sponsor storyblocks is a small part of this video save time and money with storyblocks by getting studio quality stock video clips for a fraction of the cost check it out today at the link below or learn more at the end of this video now i got a cop to this although i've been one of the most vocal reviewers trying to get decent webcams into laptops we expect that you're just going to use your phone quality look how much better this one looks so it's not even a current gen phone the webcam falls considerably short of the surface laptop after chatting with some engineers at hp i might also be partially responsible for them being so bad but first to understand what makes a camera bad we have to talk about what makes one good starting with the sensor this sony fx6 features an enormous 35 millimeter wide full-frame sensor and when it comes to cameras size matters all other things being equal the bigger the sensor the more light it can collect on each pixel improving color fidelity and greatly improving performance in low light conditions so problem number one is that due to space constraints webcams use super small sensors typically in the range of about two to five millimeters wide that's the bit i'm concerned i may have influenced the thing is as pressure from consumers and reviewers mounted for the bezels on laptops to shrink so did the webcams shrink i mean we were stoked when dell announced refreshed xps models with top mounted webcams that didn't look up the user's nose and i do still think that was a worthwhile trade-off but the results are not incredible but does shrinking the bezel really make that much of a difference yes actually let me show you in the dragonfly max hp actually increased the bezel size compared to the last model to accommodate a five millimeter sensor quick correction here we said the sensor on the dragonfly was five millimeters because well we were told was a fifth of an inch and a fifth of an inch is five millimeters in actual fact it's 3.63 millimeters because camera sensors don't use actual units instead use the vidcon nominal size which is about one and a half times larger than the actual dimensions of the sensor this is something that was decided by camera marketers in the 90s to try and sell their super small sensor digital cameras still much bigger sensor than the dell but not quite as big as we originally thought anyway back to the Linus now that's still only two percent of the size of the fx6 i just showed you but it's also a whopping five times the size of the 2.2 millimeter sensor in the skinny bezel dells this bigger sensor also allows more pixels to be packed in for 1440p recording which delivers a noticeable improvement in sharpness compared to your typical 720p webcam another problem for laptop webcams is Windows hello facial recognition something that i have also championed loudly it is the best way to sign into Windows hands down but because lighting conditions might be dramatically different from one sign-in to the next it relies on built-in emitters that will illuminate your face using infrared light now digital cameras are inherently sensitive to infrared but most of them actually block it out on purpose because it causes issues with both autofocus and color saturation also it travels through some kinds of clothing which is a little awkward that's why earlier implementations of Windows hello used a separate camera dedicated to capturing ir but then in that same mad rush to shrink bezels these have been combined in some models and in spite of the software tuning that goes into these combined sensors you can still get purple splotchiness and weird noise on the dragonfly max then hp decided combined sensors were a pain in the butt they didn't want to deal with so they included a separate ir and video camera to get you the cleanest feed possible one thing they were really stoked about is a special coating they developed so you couldn't see the ir hardware apparently it was very difficult to do so um good job guys now of course you can have the biggest baddest sensor in the world and if the glass in front of it is bad your picture quality is going to be bad one of the roles that the lens plays then is to ensure that that tiny sensor gets as much light hitting it as possible now the aperture of a camera or more accurately a lens describes how big of an opening you have so the bigger the opening the more light you can get and since we already have problems with low light on such small sensors well then we should make the aperture on the lens for your webcam as wide open as possible right well yes but also no the size of your aperture not only changes how much light is let in but also the depth of field lttstory.com by the way buy a shirt so if we were to really open up the lens on the laptop it would need to have exceptional autofocus to make sure that you don't go all blurry every time you shift around in your seat now there are many ways to do autofocus probably the best way is demonstrated in sony's alpha lineup like look at how it instantly grabs focus on the keys in the shot from our tai can review it uses parts of the sensor to detect the phase of the incoming light and uses that to focus modern phones use similar tech probably at least partly because sony also supplies the sensors for apple and samsung with these super small microelectro-mechanical systems or mems that can super accurately focus the lenses as for how laptop webcams focus well they don't there simply isn't enough space like think about the thickness of your phone i mean sure it's not super chunker or anything but compared to the thickness of a laptop display phones are enormous throw in that most laptop designers want a smooth sexy curve at the edge of the display and then the cabling from the webcam microphone and Wi-Fi antennas that are usually back there and you don't have the space that you would need for multi-element lenses so just a single focus point has to be picked and that's what you're stuck with so even for the dragonfly max which is supposed to be our shining star today of a decent webcam hp focused the lens at 50 centimeters which is the average distance that someone sits from their computer during a video call and figures well you'll get acceptable focus anywhere from 30 to 90 centimeters all of this means that due largely to space constraints this is as good of an image as you can expect to be getting out of a webcam on your laptop but what if you didn't have size constraints here we've got the dell ultra sharp webcam which not only uses a larger five millimeter-ish sensor but also has a multi-element lens to improve the image quality with that said it does still lag behind the rear camera of a phone because the third critical step in squeezing the best possible image quality out of these tiny sensors is post processing apple and google for instance use techniques like sharpening and ai upscaling to enhance their performance dell apparently has not sold enough extended warranties to match apple and google's r d in this area but on the zoom call it is more than acceptable of course you can get away with mediocre video just fine if your audio quality is good now simple laptop microphones have one or sometimes two little holes usually near the screen to capture your voice while better ones can use more the dragonfly elite for example has two super tiny holes in the lid that have mics behind them that sample the noise in your room and then try to cancel it out now in the past noise cancellation was only really good for removing constant noises like a loud air conditioner not as good for short noises like a dog barking or police sirens to combat this ai noise cancellation can also be used which we demonstrated in this video about rtx voice it's kind of amazing how good it is at removing random noises and i'm going to be very impressed if rgx is able to get rid of it so then the bad news today is that there are serious constraints to improving webcam quality in laptops but the good news is that they can get better and some laptop manufacturers are beginning to take the problem seriously all it took was everyone working from home due to a global pandemic i will have to be more careful what i ask for in the future that is some real monkey paw stuff right there thanks to storyblocks by the way for sponsoring today's video storyblocks helps you bring your stories to life without sacrifices due
