HTC explains why 4 megapixels are better than 8

With its flagship phone, the HTC 4.7 inch One, HTC made the right choice seemingly bewildering opt for a 4-megapixel camera instead of an 8 - or 13-megapixel camera of the kind seen on the high-end smartphone rivals. This does not seem to bother the Taiwanese firm, however, who insists that dropping the megapixel count on its "Ultrapixel" camera "do the right thing for the picture quality." Ultrapixel The 4-megapixel sensor measures third of an inch, which is the same size as the sensors found in phones like the iPhone 8-or 5 megapixel Nokia Lumia 920. Gambit HTC is less than megapixel sensor of the same size means that each pixel is large, and allows you to spend more light and produces better pictures in low light conditions.

"I think it's just become a really easy turnover metric," director of special projects HTC Symon Whitehorn said, explaining the decision to withdraw from HTC running megapixel arms fully. "In the camera industry, he became "more megapixels for the same price or less money" -. A metric very easy for consumers to cling "

"It's a risk, it is certainly a risk that we take," Whitehorn acknowledged before me at a briefing. "Doing the right thing for image quality, it is something risky, because people are so attached to this issue megapixels."

Each pixel on HTC backlit sensor has an area of ​​4 square microns. For comparison, each pixel sensor 8 megapixel HTC last year One X has an area of ​​1.96 square microns per pixel.

"We have long known in the imaging industry that increasing the number of megapixels often increases the signal to noise ratio," Whitehorn said: "So, we have a problem with more noise in the images, simply because the sampling rate. This means that these images become noisier, the low light performance down because you do not absorb enough light. '

Excellent guide my colleague Jessica Dolcourt for details megapixel arms race that further. Gartner analyst, says Jon Erensen: "The light [goes] well and strikes the photosensitive part of the image sensor captures the light So if you do well smaller light is more difficult to make the photo. a sensitive part of the sensor. '
Keep smartphones cut

So if large pixels to make more class pictures, why not appropriate megapixel camera always opt for so many people?

The reason is that these gadgets can incorporate larger sensors, which frees up more space for more pixels. HTC does not want to increase the size of its sensor, for fear of swelling on the phone itself.

"If you cultivate the sensor wide to accommodate large pixels and a higher number of pixels, you have to grow all the camera," Whitehorn said. Nokia 808 PureView had a 1/1.2-inch sensor huge example, but the owners had to put up with a chunky camera unit came from the rear.

If another manufacturer considers large dimensions to be worthy of an award for the image quality, however, could see its new HTC snapper quickly behind.

HTC lower megapixel trick is also no guarantee of exceptional photographs, because there are a lot of software and hardware factors that go into crafting a killer picture. Ultimately, we will not know if playing the Taiwanese company has been successful until we get the One HTC in our laboratory tests and imaging prowess compared to other smartphones.

Pressure on HTC to produce a high-end mobile has never been so high. After two years of observation Samsung devouring slice of the pie society smartphone, HTC is now faced with falling profits and the imminent threat of Samsung Galaxy S3 monitoring. If HTC does not live up to the hype, it could cause problems for the company that first brought Android into the spotlight.

Is that the way to regain the crown HTC Android? What do you think of lower megapixel company tactics? Do you think the race megapixels is getting out of hand? Express yourself in the comments below.
