Today most users want to do more than talk on the phone with your smartphone. With the boom of social networks has increased significantly the number of photographs taken in mobility and immediacy with which we share with our contacts. Therefore most manufacturers are paying particular attention to the section of their mobile photographic stars. Today HTC has taken a step further by presenting its technology HTC Ultrapixel.

The resolution is not everything

A photographic level, in recent years the race was to see who took out the camera with more megapixels. The resolution is an important factor, yes, but also a pure marketing factor: once after a certain amount of megapixels the human eye is unable to appreciate differences according to image sizes being their only advantage the better digital zoom. Be other factors that determine the quality of the picture.

But the resolution is something that can be measured and compared to the competition, hence the special emphasis of taking the camera with greater resolution. I can assure you in a brochure that my camera takes better pictures than the competition but everything is an act of faith if consumers believe us or not. Now to say that my camera has more resolution than the opponent if it is a valid objective statement.

HTC Ultrapixel reduces the number of pixels for best results

Can better pictures then reducing the resolution? Definitely yes. Since according to the pixel resolutions are too small to catch the light as well as they should. Moreover, we move in dimensions telephony quite small, so I can not always put a bigger sensor to keep the resolution but with the larger pixels.

That's one of the main new features of HTC Ultrapixel. It is simply using a smaller resolution, approximately 4MP, with a pixel size larger than usual in mobile telephony, about two microns. As a result the camera is capable of capturing up to 300% more light, essential factor to take pictures in low-light, precisely one of the weaknesses of most mobile phone cameras.

Luminosity: key

Whether the light is captured on photographic film or converted to ones and zeros by a processor, a photograph will never cease to be so, light captured. Hence, the resolution of a camera is not everything, but another important factor to consider is the lens aperture. The higher the light aperture passes through the lens and is detected by the sensor.

The HTC One has an f/2.0 aperture, which makes for a 44% more light than the sensor of the iPhone 5 and almost 90% more than the Samsung Galaxy S III. By having better opening than its rivals better captures light and, as happened with Ultrapixel HTC, the result brings a picture with better colors and sharp detail in low light environments.

Optical Image Stabilizer in both Houses

In an ideal world the photographs are always taken with a tripod. In the real world, and more on mobile photography, pictures are taken with the minimum stability. Even when something as simple as pressing the button to take the picture and are causing vibrations in the terminal that can be reflected in the photograph.

The HTC One has optical image stabilizers that eliminate as much as possible these vibrations, allowing sharper shooting. A nice novelty is that the front camera also features optical image stabilization this provision being rarer to find in a mobile terminal.

Typically in such cases is to pull software image stabilizers are not as effective as simply processed the photographs afterwards to improve it by blurring algorithms. The optical stabilization is usually a mechanical system located between the lenses of the camera that avoids a greater or lesser extent than those vibrations entering the processing chain, achieving a better result.

What about the video?

Video recording is also greatly benefit from these improvements. The HTC One is not only able to record Full HD 1080p with both cameras but, thanks to HTC imageCHIP processing chip is capable of recording video continuously at that resolution HDR mode.

Besides the HTC One incorporates improved focus speed reducing it to an average of less than 200ms. This allows video images are almost permanently focused, avoiding annoying those times when the image becomes blurry as the camera focus recovered.

In summary

HTC takes a fairly risky bet in a world dominated by numbers and the quantities that can be measured and compared but nevertheless believe they have made a right decision. Differentiation from the competition is vital and can not be denied that, at least, talk discussing Ultrapixel HTC and HTC Camera One will see that this behaves when put side by side with their rivals.
