The technology of photography on mobile phones today (Part 2)

Ultrapixel Technology:

The “number of dots” on the camera is not a determinant of image quality. Instead of just racing “dots” on the camera, HTC has chosen a separate path with technology called Ultrapixel.

Equipped for the first time on the HTC One (aka HTC One M7), Ultrapixel technology will increase the pixel size by 3 times compared to normal.

That is, 1 pixel using Ultrapixel technology will capture the bright points, image details 3-4 times more than a normal pixel, so the photo will have better quality than the light, color, and definition.

This is a pretty good technology. However, the 4 MP camera on the M7 and M8 is a drawback, not satisfied with users, even though they possess Ultrapixel technology. For some users who only take photos in a basic way, this feature has nothing to blame.

However, taking pictures on the M7 and M8 will not satisfy some of the following users:

  • Users like taking a big picture, then cutting it down.
  • Users have the habit of enlarging photos after shooting.
  • Ultrapixel technology will increase the pixel size by 3-4 times the normal.
  • Dual cameras (typical HTC One M8):

Have you ever wondered why the HTC One M8 has a rear camera? What is the camera used for?

This is considered a design disadvantage on the HTC One M8, but it is an advantage in photography technology. The HTC One M8 will use one camera to take photos, the other will be used to measure the depth of the image, thereby handling post-production better.

Thanks to the later camera duo, HTC One M8 has the special image processing capabilities that not all phones have (the ability to capture pre-focus after, the ability to remove fonts, blur the background, create effects 3D applications, …).

Usually on other smartphones, we have to perform the focus first, then take a picture. But there is no need for the dual camera on the M8, we can take a picture first, then still be able to perform focus operations on the captured images.

Besides, the ability to remove fonts, open the background, 3D effects, … is also a feature on HTC One M8. Although some of Sony, Samsung or Nokia can do this, they are not as good as the dual camera on HTC One M8.

OIS optical stabilization technology:

In the past, this technology was only available in professional cameras and was quite expensive.

However, with the current technology development speed, nothing is impossible. Manufacturers are now able to bring this OIS optical stabilization public to their smartphones.

As a pioneer in this movement, Nokia has researched, developed and brought it to users with the Lumia 920 phone, the first phone equipped with optical image stabilization (OIS).

Not to be outdone, other smartphone manufacturers are also competing with this OIS optical image stabilization technology on their products, typically some big players like Apple, Samsung, Sony, LG, …
