Introduction
HTC made a big splash the other day with the announcement of their next flagship, HTC One.
Besides the general upgrades in almost all departments, they also
presented us with a new type of camera. First of all, it's part of an
elite club by offering optical image stabilization much like the Nokia
Lumia 920. And secondly, instead of increasing the megapixels of the
sensor, they've actually decreased them, while keeping the physical
sensor size the same. As a result, the photosites on the HTC One sensor
are up to three times larger than on regular 12-13MP cameraphones.
Both of these innovations bring a promise for exceptional low light
performance, which should read as: longer hand-held exposures, high
levels of detail and low levels of digital noise.
HTC One vs. iPhone 5 camera shootout surfaces, we compare |
The new camera system got us so excited that we just couldn't wait to see what it's capable of. Unfortunately, the conditions at the launch event were far from proper for testing the camera out.
Luckily, we found a camera shootout by the guys over at CNET Asia,
who had the HTC One in the comfort of their office for a short while.
They were quick to pit it against the iPhone 5 in several test
situations and published the full-res test samples.
Comparing image quality of full-size camera samples of drastically
different resolution is a daunting task, we decided to fill in by
offering you our expert comments.
Unfortunately, despite the efforts of our colleagues, the source
files were not best suited for the task. When making comparison like
such, you would ideally try and achieve the same framing and exposure
across the devices to get really comparable results. We were forced to
disqualify one of the comparison scenes (the nice macro shot of flower,
which you can see in the source link) as it was shot from way closer
with the HTC One, giving it a dishonest advantage.
But still, we were as curious as you and we set out to compare the
available photos as best as we can. We've tried to equalize the
exposures where possible and we came up with some nice side-by-side
crops for you to compare. What we are looking to compare here is
resolved detail and digital noise.
Both phones at 8MP
Since both phones shoot in different resolutions, for the first round
of comparisons, we upsized the HTC One samples to 8MP (with generous
sharpening afterwards) so as to see whether it's able to resolve as much
detail as a regular 8MP camera. The performance here would be important
if say, you would like to print your photos in large paper sizes.
When upsized to 8MP, the HTC One amazingly holds its own and resolves
almost the same level of detail as the iPhone 5 in the low light studio
shot. Unfortunately, it didn't have an advantage in the levels of noise
as these were a tie.
As for the rest of the photos, where the light is better, the HTC One failed to keep up with the iPhone 5.
In better light the iPhone 5 has a clear advantage, even though its
noise suppression routine does have some sort if an issue with the
grass. It tends to smear the detail in the grassy areas, but that's more
of a factory setup issue than a deficiency of the camera module itself.
In contrast, you can see the clear advantage in the foliage. The other
two crops show a further advantage of the iPhone 5.

Downsized for sharing
Then we figured that many people don't print their photos but only
share them online. On most social websites the photos get downsized
anyway so the maximum resolution doesn't matter that much. So we went
this route, too. We downsized the originals from the iPhone and the HTC
One down to 1500px horizontal resolution, which is about 1.6MP. Facebook
can surely handle that size, we checked.
It would be wrong to think that the process of downsizing would be
only to the HTC One advantage. Downsizing lowers the perceivable digital
noise, so the iPhone's photos benefit from that operation just as well.
Downsizing the photos of both cameraphones levels out the playing
field a bit better. Unfortunately, the iPhone 5 mostly retains its
superiority in resolved detail even when you downsize all samples to
1.6MP. The outdoor scene with the grass is the only scenario where it
loses to the HTC One and that's mainly due to the noise suppression,
which kicks in and smears the grassy patches. For the rest of this
specific scene, both phones seem to resolve the same amount of detail.

Conclusion
Overall, we were a bit disappointed that we didn't see the promised
spectacular improvement from the newly developed camera system of the
HTC One. Sure, it equaled the iPhone 5 in resolved detail in one or two
cases and that's great, having in mind it only has half the resolution,
but most of the time the results were of lower quality.
We don't mean to say the HTC One takes bad pictures - it's just on
the contrary, they are quite good and we bet the optical image
stabilization will help it take much better handheld photos in low light
when compared to most other smartphones.
But is it a worthy camera for an expensive flagship phone in 2013? We
are not so sure - don't forget that a phone with a good 13MP camera
will be in an even more advantageous position than the 8MP iPhone 5. And
we will surely see many more 13MP shooters come out in 2013.
We can't help but feel that HTC is a year late to the market with
this type of camera sensor. Sure, high megapixels are not all, but
having the biggest pixels around is not enough either.
Thanks for sending this shootout our way, Dane!
