HTC One UltraPixel - 4-Megapixel Sensor On A High-End Smartphone (Part 1)

8/5/2013 9:07:36 AM

In a daring move, HTC has made an attack on the "megapixel race" in the high-end smartphone segments by placing a 4-megapixel sensor on their latest high-end smartphone products, the HTC One. They emphasize the importance of light sensitivity by using a sensor with fewer megapixels, and therefore those results in the process of gathering pixels, by a bright f/2.0 lens, as well as optical image stabilization. They claim that this combination gives them 300% more brightness than competitors with 8 and 13 megapixel smartphones, and even goes farther when calling it an "UltraPixel" sensor.

The HTC One and almost all of the other smartphones with a built-in camera make use of a small 1/3inch sensor, which means that compared to a standard digital camera, the sensor is much smaller - see the sizes compared in our guide on digital camera sensor sizes. This means that each pixel is much smaller as well, and attempting to cram an 8 or 13 megapixel sensor into a small space has made each pixel smaller, with the latest sensor using a 1.4 (8mp smartphone) or 1.1 (13mp smartphone) micron pixel size.

Compare to a compact digital camera like the Canon Powershot S110, with a 12 megapixel, 1/2.33 inch sensor, and two 2-micro pixel sizes, or a digital SLR camera like the Canon EOS 700D with an 18 megapixel APS-C sensor and 4.2 micron pixel size, and you begin to find that each pixel reaches 2x that is less bright than in a compact camera, or 4x that is less bright than a Digital SLR camera to each pixel.

It is only possible to be the One

The HTC One still employs uses a small 1/3 inch sensor, but to get more light to each pixel, it uses a 4 megapixel sensor, with two 2-micron pixel sizes. This is not the only way of the HTC One in order to improve low-light performance, it also uses a bright f/2.0 28mm wide-angle lens, and combined with the feature of optical image stabilization, its performance will be better than any other smartphones’ in low light conditions.

It is easy to unlock the shortcuts to web / cameras / etc. to create the ability of quick access to the applications you use most often. On the bottom, below the screen are the Android Home and back buttons, though strangely the third menu button only shows up when the screen is touched, occupying a part of the screen area. MicroUSB connection and charging lie at the bottom of the phone, and on top is the unlock button and headphone socket.

The unlock button is slightly lifted, but since the phone has a rectangular shape, so it may take some time to be able to work in a way that you do not need to look at it, when you first get it. On the side are the textured volume buttons.

Facing forwards are the "Beats Audio" stereo speakers, which is able to produce good quality of sound and clarity, although as expected they have low bass. The phone with the latest version of Android can access to the Google Play app market, with all the common image applications such as Instagram etc., and as an HTC phone with a few additional unique HTC applications have been included in this operating system. Performance and responsiveness of the phone and the apps are great with the programs loading quickly and the screen responding fast when touching.

The rear camera

The rear camera

The HTC One features a silver body that is made out of aluminum; and is ultra-thin, 9.3 mm thick. There is nothing to protect the lens on the rear, so a shell or the actions while using the phone camera should be carefully encouraged, and similar to other smart phones, it is important to ensure that the lens is clean because it is easy to have fingerprints on the lens. Build quality seems to be great, and the phone has been integrated the memory inside and is designed with the inside-rechargeable 2,300mAh battery.

We took a number of shots to check the responsiveness of the camera, switching from the first picture, one to one, the focusing speed etc. We took some photos and then used the average to make sure that the tests are accurate and consistent, making it easy to compare with other cameras.

·         Shutter Response: <0.05s

·         Wide – Focus / Shutter Response: 0.05s

·         Switch on Time to Taking a Photo: <15s

·         Shot to Shot without Flash: 0.2s

·         Shot to Shot with Flash: 0.9s

·         Continuous Shooting – JPEG: 9fps (20 shots)

The process of continuous shooting is at 9fps, and for 20 shots, although you are able to take more than 20 pictures. Continuous shooting time is great and there is nearly no delay in the focus process.
