Review from The Verge

If you watch the video, HTC One only has 4mp but claiming it that it has Ultrapixels. What does that mean?

It means that the pixel is as huge as dSLR pixel.

This means that the quality of the camera pixel is like dSLR although its lower resolution.

Its like you use 10MP Canon dSLR but crop it in the middle. It is that awesome. Probably the best camera ever in smartfone. Will kill off every competitiors. Nokia Pureview also lose to dSLR camera in HTC ONE.

Do you even know what a digital SLR is? the HTC phone camera is not a DSLR, nor will it every compare to one, a larger sensor and 14bit colour depth this is what really sets any DSLR from any point and shoot or phone camera.

The 2-micron pixel width in this phone???, my DSLR is over twice this 4.3-micron pixel pitch.

The proof of the quality will obviously come, but prelim reviews state that it is not as good as the Nokia.

HTC already tried this once with the HTC One, with their most stupid marketing. "HTC One Versus DSLR Images, Can You Spot The Difference?". I wrote to them and told them how stupid this marketing was. 364x268 (0.1 megapixel) photos were the comparison, so I sent them sample photo's from my Nokia N70, Blackberry 8900, HTC Desire and my 4Mp Canon G3 point and shoot. Reduced them in size to 364x268 and challenged them to tell the difference between any of them. They very quickly removed this challege from their website about 6 hours afterwards.

Don't get me wrong I am sure this camera is stunning, but it's no DLSR in terms of quality and neither is any point and shoot on the Market. Just the same as ANY cropped DLSR will compete with a full frame DSLR.

Sorry for the exaggeration. I just trying to get the point across about megapixel Vs photosites.

In answer to your question, HTC are trying to be different (Marketing move to gain lots of interest).

The pixels that gather the light are larger (Ultra), allowing more light to be captured. Meaning the camera should be amazing in low light compared to most other phone cameras.

http://www.techradar.com/news/phone-...c=rss&attr=all.

My Canon G3 point and shoot camera was only 4Mp, the photo's from this camera are stunning, great lens and sensor, 4Mp is the optimal balance (quality/noise) for this image sensor size.

more megapixels really only gives you benifit from printing larger prints, or allowing a high quality crop of a shot. How many people print about A3 type size? not many and certainly from a phone.

Not true. Higher megapixel is gimmick. Reducing megapixel and increase photosites is not gimmick. Its science.

Thanks for that in depth explanation.

And I thought that the only way to gather more light is to have a lower aperture. Well with this, it's a good move to capture low light images with more details (less depth of field). This makes it perfect for concerts.

Yup, it also reduces files sizes. This is good for phones with non expandable memory. I always choose the option to have a smaller MP as these pics are only to be viewed on a laptop. If I wanted to do prints, I'd take my dSLR to shoot pics.

Here is another explanation on the ultrapixel

I agree with what HTC says
More megapixels crammed into a sensor of the same size, ie 8, 13 mp in a sensor of the same size, will make the pixels themselves smaller. Less light is captured, more noise produced.
Reduce the amount of pixels and suddenly there are bigger pixels and more light can be captured. I think it will be good for the camera, as a cropped 2mp picture from a DSLR is waaaaay better than a 8mp picture from my incredible s or a one x.
Think of a wire grid fence, if you have more wires there will be more holes, but less light will be able to come through
Dunno how they will market it though. Makes it seem like the old nokias with 2mp cam are the best lol

Nothing. It's meaningless guff.

The HTC One has a slightly (VERY slightly) larger image sensor, and halves the number of pixels to roughly double photodiode area. That (should) mean much better low-light sensitivity and noise, but much worse resolution. (Still plenty for a typical consumer print, though.)

It simply trades off resolution for low light / noise performance. And the "Ultrapixel" doesn't exist. There have been numerous cameras in the past with the exact same pixel size as the HTC One, including camera phones. Few of them have been available for a few years, or made with current tech, but that's beside the point.

"Ultrapixel" is just a marketing brandname meant to give you the warm fuzzies and make you forget about megapixels.

Complete and utter rubbish. The smallest pixel of any SLR belong to, if I'm not mistaken, the Nikon D3200. It has nearly double the pixel size of the HTC One's camera. And even a cheap consumer DSLR lens is in a different league to a smartphone lens, especially at the center of the image frame.

It is utterly unrealistic to expect even remotely similar per-pixel image quality from a DSLR and the HTC One, even for the central four megapixel crop.
