[Mobile Cellphone Info] HTC One vs HTC One Camera Performance After the Update

Mobile Cellphone Info has posted a new item, 'HTC One vs HTC One Camera
Performance After the Update'




Last week, we caught wind of an upcoming software update for the unlocked
version of the HTC One. Firmware version1.29.401.13 finally made its way to our
devices and we took the UltraPixel camera for a spin both before and after the
update, as we wanted to have a firsthand look at the effects of the update.
Although only a 4-megapixel camera,we found in prior tests that the UltraPixel
camera on the One packs quite a wallop, performing quite well in various areas:
HDR, low-light and even well-lit conditions.The supposed changelog, according to
SlashGears report last week, states this update brings various improvements in
the form of:


Improvement to sound capture with Zoe
Noise reduction in slow motion movie capture
Improved color reproduction and dynamic range (reduced over-exposure in non-HDR
images) in certain conditions
Fix to display correct ISO in EXIF information when ISO settings are manually
changed by the user
Improved system performance and stability

We took the One around and tested its performance on both old and new software.
With only one unlocked model, we were forced to take the pictures at different
times, which made it quite difficult to frame the pictures exactly the same in
every scenario. Despite that small speed bump, however, the improvements albeit
slight are still noticeable in many of the stills found below.
In all the images below, the images on the left are pre-update and on the right
are pictures from after applying the update.You will notice that these
improvements are more about slight modifications and taming the previous
firmware, versus a drastic overhaul.

The most prominent improvement is in the reduced over-exposure in non-HDR
pictures. This only affects some specific scenarios, but the scene above is a
perfect example of just how it works. The post-update image is, overall, darker
than the similar picture taken pre-update. The difference is that the clouds are
totally visible. There is some aberrationaround the edges of the clouds, but
they are visible. In the pre-update image, the grass is greener and brighter,
but the clouds are only just visible above the tree line. Although the grass and
trees look more vibrant in the first photo, the latter photo, the one taken
after the update, is more accurate and true to life.

In this case, although the images are framed slightly different, the
enhancements are not visible. The color, contrast, brightness and focus are
virtually spot-on, though the light in the back of the photo (along the
sidewalk) is brighter and more accurate.

Above is yet another scenario where the improvements of the most recent update
are not noticeable. The images are on par with one another.

The HDR performance after the update seems a tad more natural. Where the
balusterson the pre-update image (left) are brighter than usual, the balusterson
the post-update photo are more true to life.

In many scenarios, colors seemed more vibrant after the update. The right image,
for example, shows a more balanced, true to life view of the leaves and pine
needles. The pre-update image (left) was quick to over-expose, even in a darker
image.


Some colors seem to have been toned down ever-so-slightly. Its not immediately
visible, but as seen in the close-up of the leaf, in the post-update photo
(right),the greens are less saturated and slightly more warm than they in the
pre-update photo (left).

Low-light performance is on par with before, but yet again we can see richer
colors in the globe around the light bulb.


One thing worth mentioning is that even post-update, whites still tend to
over-expose from time to time. For instance, in the picture of figurines after
the update (right), the desk around the blue Iron Mans feet is slightly
blown-out. In the similar image prior to the update, the image is not
over-exposed.
That said, the colors are richer in the photo on the right. The blue is more
blue, and the skin ton on the Psy figurines face is definitely more saturated.

Overall, we have to say that while these improvements are, more or less, slight
refinements and will likely go unnoticed by most, they are in fact improvements.
And were definitely happy to see a lower tendency of over-exposing. In all, this
update isnt going to blow anyone away, but it lends more credence to the fact
that megapixels only matter so much. Software and optics play a major part, as
well.
Below, you will find the video samples, in which there werent a lot of changes.
