The Samsung Galaxy S4 and LG Optimus G Pro are the freshest examples of this megapixel push, but even last January's Pantech Discover (1. October's LG Optimus G for Sprint (1. Nokia 8. 08 Pure.

Shootout!: Samsung Galaxy S4 versus HTC One and i. Phone 5. Championing that perception head- on is HTC, the same company that not too long ago boasted about the 1.
Titan II. Now, in its HTC One flagship, the smartphone maker dials down the megapixel count to 4 megapixels, which HTC fancifully terms "Ultrapixels," arguing that the lager pixel size throws back the blinds to let in much more light. In this lies the reminder (something photography nuts will tell you) that it's quite possible for an excellent 5- megapixel camera to produce photos you prefer over a shoddy 1. The number of megapixels alone is no guarantee of heightened photographic performance. Instead, the formula for fantastic photos comes down to the entire camera module, which includes the size and material of the main camera lens, the light sensor, the image processing hardware, and the software that ties it all together.

So let's dive in. Note: As always with this column, if you already consider yourself an expert, then this article is probably not for you. Key ingredient No. The sensor. Most budding and professional photographers will tell you that the most important ingredient in the optical system is the sensor, because that's the part that captures the light.
The sensor is essentially the "film" material of a digital camera. No light, no photo. Light enters through the camera lens, then passes to the camera sensor, which receives the information and translates it into an electronic signal. From there, the image processor creates the image and fine- tunes it to correct for a typical set of photographic flaws, like noise. The size of the image sensor is extremely important. In general, the larger the sensor, the larger your pixels, and the larger the pixels, the more light you can collect. The more light you can catch, the better your image can be.

Berry Z1. 0. Josh Miller/CNET. The experts I spoke with for this story had colorful ways of describing the relationship between pixels and sensors, but "buckets of water" or "wells" were a favorite (intentionally oversimplified) analogy. Imagine you have buckets (pixels) laid out on a blacktop (sensor). You want to collect the most water (light) in those buckets as possible.
To extend the water- and- bucket analogy, the larger the sensor you have (blacktop), the larger the pixels (buckets) you can put onto it, and the more light (water) you can collect. Larger sensors are the reason that 8 megapixels from a digital SLR camera (or 5 or 1.
You get roughly the same number of pixels, but the pixels on the d. SLR get to be larger, and therefore let in more light. More light (generally) equals less- noisy images and greater dynamic range. The fallacy of megapixels. You can start to see that cramming more pixels onto a sensor may not be the best way to increase pixel resolution. That hasn't stopped the cell phone industry from doing just that.
Jon Erensen, a Gartner analyst who has covered camera sensors, remembers when we collectively made the leap from 1- megapixel to 2- megapixel shooters."They would make the pixel sizes smaller [to fit in more pixels]," Erensen told me over the phone, "but keep the image sensor the same." "What ended up happening is that the light would go into the well [the 'bucket'] and hit the photo- sensitive part of the image sensor, capturing the light. So if you make the wells smaller, the light has a harder time getting to the photo- sensitive part of the sensor. In the end, increased resolution wasn't worth very much. Noise increased," he said. The relationship between the number of pixels and the physical size of the sensor is why some 8- megapixel cameras can outperform some 1. There's more involved, too.
A slim smartphone limits the sensor size for one, and moving up the megapixel ladder without increasing the sensor size can degrade the photo quality by letting in less light than you could get with slightly fewer megapixels. Then again, drastically shrunken pixel sizes aren't always the result when you increase your megapixels. HTC's Bjorn Kilburn, vice president of portfolio strategy, shared that the pixel size on the 1. Titan II measures 1. HTC One X's 8 pixels measures a slightly larger 1. As a result, the photo quality on both these HTC smartphones should be comparable at a pixel- by- pixel level.
Phone makers like HTC are adding more fanciful modes yet, like this sequence shot setting on the One. Sarah Tew/CNET. Unfortunately, most smartphone makers don't share granular detail about their camera components and sensor size, so until we test them, the quality is largely up in the air. Even if smartphone makers did release the details, I'm not sure how scrutable those specs would be to the majority of smartphone shoppers. For more information on the interplay between megapixels and sensors, check out the excellent description in CNET's digital camera buying guide. What about Nokia's 4.
Pure. View? The story behind the 8. Pure. View smartphone as Nokia tells it is really interesting. CNET Senior Editor Josh Goldman has written one of the best explanations of the Nokia 8. Pureview's 4. 1- megapixel camera that I've seen.
I strongly suggest you read it. In the meantime, here's a short summary of what's going on. Juha (pronounce it YOO- hah) Alakarhu is head of camera technologies at Nokia, where he works within the Smart Devices team. Alakarhu explained to me that although Nokia has engineered the 8.
Usually, when you use the digital zoom on your phone, you're blowing up and cropping an image to see each pixel up close. You all know what that can look like: grainy, blocky, and not always as sharply focused or as colorful as you'd like. Shot with the Nokia 8.
Pure. View. Nokia. In the 8. 08 Pure. View, Nokia uses a process called "oversampling," which - - for the 8. If you zoom in on an object, you're simply seeing part of the image that's already there, rather than scaling up.
This method should translate to higher- resolution digital printouts and zoom- ins than you'd normally see. It's taken over five years to create the technology within the 8. Pure. View, Alakarhu said. Not only does the 8.
It's this set of instructions that Nokia terms Pure. View, not the sensor size alone. As CNET's Goldman has pointed out, this is an unusually large sensor for a smartphone, and it's also larger than sensors found on the vast majority of point- and- shoot cameras. Key ingredient No. Image processing. In addition to the size and quality of the lens and sensor, there's also the image processor. Most modern high- end smartphone CPUs have dedicated graphics processors built into the chip, which, being hardware- accelerated and not just software- dependent, can quickly render images like photos, videos, and games without overtaxing the main application processor.
HTC and Samsung have been pushing continuous- burst mode hard, averaging one shot in a tenth of a second or less, thanks to separate hardware- accelerated image processors that can capture shots like nobody's business. However, since burst mode doesn't give you time to focus, expect to see some blur. I promised that there was software bridging the hardware and the final image, and there is. Algorithms and other logic are what create the final image output on the phone's screen. This is where the most subjective element of photography comes in: how your eye interprets the quality of color, the photo's sharpness, and so on.
The image processor is also what helps achieve zero shutter lag, when the camera captures the photo when you press the capture button, not a beat or two after. Wait, there's more. There's much more to know about the competing technology that goes into sensors, but backside- illuminated sensors are starting to be used much more in smartphones. This type of sensor is often synonymous with better low- light performance because it increases photosensitivity. However, if you shoot in bright light, it can also blow out your image.
Here are more details on how backside illumination works. The i. Phone 5 has fewer controls, but great image processing. CNET. Low- light performance, by the way, is turning into a serious battleground for bragging rights. Nokia's Lumia 9. 20 and Apple's i.
Phone 5 currently rule this shadowy realm, with HTC's One vastly outperforming the Samsung Galaxy S4, which has no automatic low- light adjustments to speak of (though there are several shooting modes). Backing out of the low- light rabbit hole, it's important to note that the camera's sensor size and image processor may be the most crucial elements for creating quality smartphone photos, but other considerations come into play.
Higher- quality components, for example, can help tease out better photos, but they could also cost more, which could lead to a marginally pricier camera. While the cost of a camera module is only one part of the total cost, Gartner analyst Erensen said that high- end parts could double the price of a basic camera set, and thought that parts could cost $1. The smartphone makers I contacted for this article, like Samsung and Nokia, wouldn't share sourcing or pricing information.
Usability is king. It's quickly becoming a well- worn adage that the best camera is the one you have on you.

Important information: Many features and mobile wireless services are network dependent and require network support. Some networks have limitations that affect how you can use phone features. For instance, not all networks support certain language- dependent characters and services. A service provider also may have requested that certain features be disabled in a phone. If so, they will not appear in the phone's menu.
Contact your service provider for more information and to determine if a service plan includes the features and services that you want to use. Please be aware that the battery talk and standby times are estimated times only. Battery usage varies with network configuration, signal strength, features used, battery age and condition, charging practices, temperatures to which battery is exposed, type of digital mode (tdma, cdma, GSM or Analog), and certain other factors. Basically, battery time is used both when the phone is being used in standby mode, as well as, when the phone is used in talk time mode. Both modes reduce the overall time of possible battery usage. In order to maximize your battery's talk time and stand by time, make sure that you first charge it fully for 2. Complete this process for the next few charging cycles making sure that the battery is drained fully before each charge.
