At the launch of HTC One, we were most impressed by the unique "UltraPixel" camera in addition to the beautiful aluminum one-piece body of One. HTC even claims that "Megapixel is a myth" (the pixel debate is useless). Can One with only 4 million pixels justify itself? Let's have a look.

Introduction

First of all, at the beginning of the article, the editor will still be impatient to introduce the "Ultrapixel" technology. According to the official statement of HTC. Equipped with this technology HTC One Mobile phones have larger pixel sensitivity points in terms of camera sensors to get more light. HTC officially announced that the camera can take photos with higher sharpness, higher contrast and brightness. Of course, the above are all the advantages of One.

On the other hand, HTC claims that 400 pixels is actually enough for most consumers, even if you want to print the pictures taken. However, in fact, for some users with special needs, 4 million pixels is not enough to meet their needs, especially when you need to enlarge the image for cutting.

In fact, the camera sensor of HTC One is not larger than that of other mobile phones. The One is a 1/3.2 inch sensor, and the sensor of iPhone 5, Galaxy S3 and Lumia 920 is also 1/3.2 inch. When it comes to big sense elements, it can only be said to be 1/1.2 inch of the Nokia 808 phone. Therefore, HTC actually increases the size of each photosensitive point by reducing the number of pixels in the same area. Therefore, larger pixels can absorb light better.

Finally, we found that HTC actually wants to achieve the best balance between trade-offs. Did HTC achieve its goal? Now let's take a look at One and the photo balance sheet to absorb the best and most balanced iPhone 5 Compare.

Outdoor normal light

I believe you can also see the difference between the One and the iPhone 5 in color performance. Here, I put the building together for comparison after zooming in. Airfriends can judge by themselves after reading it.

If the fans pay attention to the tracking report and analysis of the photo effect of One before the editor（ HTC still needs efforts? Comparison of photo effects between HTC One and Sony Xperia Z ）I believe that I have more or less knowledge. After the continuous tracking of One photos by the editor, we can draw the following conclusion: In outdoor (or with sufficient light) conditions, One will be white in color performance, the overall color is not sharp enough (although the gap is small, but it can be observed), and can not play the Ultrapixel advantage. Plus low pixels, the photographic performance under sufficient light needs to be strengthened.

The following two pictures can also reflect the same problem

In general, One again encountered the problem of dark and gray colors.

Dark light at night

Dark light shooting is also the focus of HTC's promotion of One. How about the actual performance? We will look at the sample and analyze again!

▼ Indoor dim light of HTC One (click to view the original picture)

▼ Indoor dim light of iPhone 5 (click to view the original picture)

▼ Contrast after amplification (note the noise in the red box)

Dark light is naturally the focus of HTC, so the editor should also make a good analysis! By viewing the EXIF information of One, you can see that The exposure time is 1/14 second, and ISO is controlled at 680 ； In contrast, although the exposure time of iPhone 5 is controlled to 1/15, However, the ISO was raised to 800, and the noise increased accordingly. You can also see it through pictures. Although the iPhone has improved ISO, the brightness of the two pictures is not much different. In this game, I think HTC wins!

The following is a more vicious dark light environment, which is also a real test of the dark light ability of the two mobile phones. Can HTC One justify itself? Let's take a look at the sample first.

▼ HTC One dim light shooting (click to see the original picture, and interested users can analyze by themselves)

▼ iPhone 5 dim light shooting

▼ The following will be the screenshots of the details! Watch the noise control carefully (click to view the large picture)

I believe that after looking at the two magnified contrast pictures, the iPhone 5 has serious noise compared with the One. By checking the EXIF information of One sample, the editor found that The exposure time has been extended to an astonishing 1/4 second! ISO still remains at 800; In contrast, the difference between iPhone 5 is very obvious. Not only does the exposure time reach 1/15 second, but ISO also reaches 3200. To further confirm the upper limit of the exposure time of iPhone 5, I made a series of photos in an almost completely dark room to test its exposure time. After checking the EXIF information, it is found that 1/15 second and 3200 ISO are the highest values of iPhone.

As for why HTC One "dares" to extend the exposure time so boldly, it is associated with HTC One's biaxial optical anti shake technology. Xiao Bian believes that in addition to the larger sub pixel of One, which can absorb more light, there is also the support of optical anti shake technology to extend the exposure and improve the shooting quality while ensuring the film yield. Shooting at night, Xiao Bian thought that the victory was obvious.

summary

After the above analysis, plus the relevant tracking report analysis that has been carried out. At present, the following conclusions can be drawn:

• With sufficient outdoor light, HTC One is almost at a comprehensive disadvantage. Why "comprehensive". In addition to the disadvantageous factors of resolution (the huge difference between 4 million and 8 million and 13 million), One is not sharp enough in color sharpness but grayish. At this time, One can not give full play to the advantages of large light sensitive pixels, and the optical anti shake performance is useless (except for video shooting, of course).
• With the optical anti shake technology One, the ability to shoot at night has almost become a "fighter" in mobile phones! Although the editor has not collected the photo comparison between One and Lumia 920, it is still worth looking forward to. You should know that there are only two mobile phones with optical anti shake technology at present - HTC One and Lumia 920
