Trends in Smartphone Cameras
Recently, I became annoyed with the way Dropbox camera upload just dumps images with no organization into the “/Camera Uploads” folder, and set out to organize things. I have auto upload enabled for basically all the smartphones I get sampled or use on a daily basis, and this became a problem with all the sample photos and screenshots I take and want to use. I wrote a python script to parse EXIF data, then sort the images into appropriate camera make and model folders to organize things. An aberration of having this script put together was easy statistical analysis of the over four thousand images I’ve captured on smartphones from both rear and front facing cameras, and I was curious about just how much storage space the megapixel race is costing us. In addition I was curious about whether there’s much of a trend among certain OEMs and the compression settings they choose for their cameras. The plot shows a number of interesting groupings, and without even doing a regression we can see that indeed storage space is unsurprisingly being consumed more by larger images, with the 13 MP cameras already consuming close to 5 MB or more per image.
If we sort them into bins we can see that most really end up between a few KB in size to 6 MB, with the panoramas and other large stitched composites providing a long tail out to 16 MB or more.
The conclusion for the broader industry trend is that smartphones are or are poised to begin displacing the role of a traditional point and shoot camera. The truth is that certain OEMs who already have a point and shoot business can easily port some of their engineering expertise to making smartphone cameras better, those without any previous business are at a disadvantage, at least initially. In addition we see that experiences and features are still highly volatile, there’s real innovation happening on the smartphone side.

How can I start reading when there is no mention of any Nokia products? HTC One should not be even included in the article because it's not even considered a breakthrough in camera phones.Krysto - Saturday, February 23, 2013 - link
Next time try reading more than the first paragraph.Diagrafeas - Saturday, February 23, 2013 - link
How many MP or to be more accurate Million Sub Pixels are these Nokia sensors because these numbers come surely after interpolation or pixel shift or something...Also do we have information about HTC One sensor?
Is it one Bayer sensor or 2-3 stacked like Foveon ones?

While HTC definitely deserves credit for discontinuing a trend of ever more MPs, I don't think they went far enough. There's still an unclenched status quo thinking in smartphones about sensor size. Virtually all of them have a 1/3.2" sensor.No one has even thought about making that one much larger? Even after Nokia showed Pureview 808 and got a lot of praise for it? Really? What is wrong with all these companies? Do they want us to spell it out for them?
I get that clean phone design is a big factor, but you can't just keep doing things the same way everyone has always done it. And then they wonder why they can't beat Samsung. Sure Samsung has a lot of marketing power, but they also play a little less safe than everyone else. They add the S-pen to devices, even though it adds quite a bit of cost and then they need that device to compete with others, so it's a risk for them that the consumers might not want to pay extra for it - but they still do it. They also started the "phablet" trend all by themselves. And while these things don't necessarily have mass market appeal, they get a lot of publicity and quite a lot of passionate fans and customers for those devices.
So why aren't the other manufacturers experimenting in the same way not just with incrementally better cameras, but WAY better cameras, that they put in phones. I'm talking putting camera capabilities in a phone that could add $100 or even $200 to the retail price of the device. That's being BOLD in the market. That's being DIFFERENT.
So I want to see them come up with devices that have 1" large sensors of 5-8 MP, with some high quality lenses, and powerful ISP's and software behind them. Create that and you get at least 3 different types of consumers coming to buy that phone (the type of consumers that yell :SHUT UP AND TAKE MY MONEY!): professional photographers (they buy thousands of dollars worth of equipment for fun, and they need phones, too), amateur photographers (people who love taking great photos with their phones), and you'd also pretty much convert the whole (in time of course) point and shoot market to your device.
So the potential for sales is right there for reaping. And these people wouldn't get about a slight bump on the back, if they can get a phone that is 5x better than anything else on the market at the time of shipping. I want to see that kind of LEAP in smartphone cameras, not just these regular "2013 camera is slightly better than the 2012 camera", and so on.

I think you're generally right, but these days from manufacturer's point of view it's very easy to sink the ship by being bold and not being understood well by the market/consumers. It is then very easy for their opponents to do nasty counter marketing to make things worse even further.As a photographer myself I really would like to see a no compromise smartphone camera (give glass!!! give me bigger sensor with less megapixels!!!), but I guess we're not at that point just yet. Only recently manufacturers of compact cameras started to show some interest for making cameras geared toward serious photography, so I guess it's still a few years wait to see that approach in the smartphone world.

Besides I guess 1" sensor in a smartphone will never happen due to physical constrains - you need a lot of light gathering power to lit such a huge sensor not to mention the focal distance needs to be considerably bigger for the field of view not to be ultra wideKrysto - Saturday, February 23, 2013 - link
Pureview 808 had a 1/1.2" which is pretty close, and didn't look too bad:http://images.fonearena.com/blog/wp-content/upload...

That's kinda the point. It didn't look TOO BAD, which is a far cry from looking great. I also remember reading some reviews which complained about the ergonomics. Also the pure view was more of a niche experimental product.It's kind of like some article that I read years agonwhere itnsaidnthat according to research (or a survey or something) consumers, when buying a tv), were most interested in size THEN image quality and then all the other stuff. Most phone buyers are similar, they want a better camera but are not willing to give up styling for it, at least not without some re-education.
As for HTC not going far enough. I think it has more to do with the fact that they're not doing too well as is and most likely feel like they're taking enough risks at the moment.
Personally I would be willing to give up some slimness (but hopefully not styling) for a decidedly improved camera. I hope HTC does well with the One and that they are willing to experiment a bit more in future generations. But then again I am not sure yet how I feel about the loss in detail. Another site got their hands on a One and have some comparison shots between the On eand the iPhone 5
Tarwin - Saturday, February 23, 2013 - link
Oops, accidentally pressed post.Well, in the comparison shots I prefernthe images ofnthe One, but I occasionally neednthe detail procided with 8MP but then again only sometimes. When 4K TVs vecome mainstream and I also have one then I'll kost likely think it's the minimum pics should be taken at.

They can make it more stylish than that. I wouldn't mind if my phone looked a bit like a point and shoot, and didn't have a perfectly flat back surface.Again, I'm not saying these phones are for everyone. Note phones are not for everyone either. In fact I don't think I can ever see myself owning a Note phone. But yet millions of people have them, and those who do love it, and wouldn't imagine going back to a smaller phone.
That's the type of market I think such a phone can target. A niche market indeed, but a big niche nonetheless. And I would be part of that niche.
