DSP and ISP
Huawei has greatly relied on the photo for his part P9 as the Chinese manufacturer has worked with Leica, the German specialist in photography. We decided to compare the photographic capabilities of P9 facing Mate 8 that shares some common components. The new P9, wearing his Leica certification, he holds the recipe to provide better results than PHABLET Huawei? Response images.
During the presentation of the P9 in London, Huawei has stressed the photograph aspect of its new smartphone. The Chinese company has even invited some big names in photography and film who came on stage, boast performance and P9 P9 Plus in the field of photography. From a technical standpoint, the P9 P9 and more radically change the situation in relation to what was done at Huawei. Certainly, the technique was already known double image sensor with the Honor 6+, but here the Asian manufacturer has gone even one step further, assisted in its work by the German Leica.
Two cameras in a
P9 P9 More and therefore incorporate two sensors, Sony IMX286. Unlike Honor 6+, each sensor has its own role as one is dedicated to capturing the color information via the famous Bayer matrix, which allows to face each pixel a blue filter, red or green .
The other sensor plays a completely different role, since it lacks the famous matrix, and thus captures only monochrome information that will be used for contrast pictures. In addition, having fewer filters in the black and white camera would capture twice the light, according to Huawei, a color camera. Finally, both sensors may perform a triangulation operation to measure the distance of a subject and adjust the focus. This is also done by measuring the contrast, but also thanks to laser infrared sensor.

12 megapixel sensor
Sony IMX286 16 megapixels
Size NC sensor 1 / 2.8 ”

Aperture f / 2.2 f / 2.0
27 mm focal NC
Optical stabilization Yes No
Sony IMX179 8 megapixels
The dual sensor also allows you to play with the opening of the camera. Materially, the lens is able to cover a focal length of f / 2.2 to f / 27. In software, Huawei manages to get down to f / 0.95, but only up to f / 16. Although Huawei has not detailed the partnership with Leica, it seems that the objectives were designed by the German manufacturer, as they are called “Summarit H”, similar to the brand objectives.
A new couple DSP / ISP
Technically, the new SoC uses Huawei Kirin 955 that incorporates a new pair DSP (Digital Signal Processor) – ISP (image processor) supposed to be more energy efficient. PSI dual heart handles merge two photos from the two sensors, optimize color and noise management while the DSP handles the post-processing, including real-time filters or video stabilization digital.
Does all this gear benefits the P9 facing Mate 8? The latter is rather well endowed in terms of picture with a Sony IMX298 camera sensor of 16 megapixels, optically stabilized, with an f / 2.0 and an update phase detection point. Video enthusiasts will note that the two devices are not able to shoot in 4K.
A P9 greater than the Mate 8
We performed some comparative shots to try to separate the Huawei P9 / P9 More and Mate 8 in the field of photography. Coupons short suspense: yes, the P9 P9 and more are much better than the Mate 8 photo, either detail-level term, contrast, color rendering and color temperature. In terms of development, we are a little more circumspect. P9 is fast, very fast in certain conditions, but a little slower when conditions are more difficult. The Mate 8 seems more consistent in this area, but a little slower in ideal conditions. The design hybrid point P9 so do not always compete with the phase detection Mate 8.
Let’s look a little more detail photos offered by the two terminals, either in landscape, portrait, macro and even at night. Besides talking a little more detail of that situation. The Mate 8 managed to capture more in low light colors, but P9 is more accurate in details at the edges, and especially the pictures are less noisy and therefore appear better. As usual, you can download the photos in original format to access the EXIF information.
On landscapes, management of contrast and sharper image is clearly visible, especially on the reliefs (doors, roofs, etc.).
Huawei Mate 8
On this sunset, again, the P9 Huawei shows its superiority over the Mate 8 in terms of definition and contrast. Shown with cranes and walls.
Huawei P9, Exposure: 1/320, ISO: 50
Huawei Mate 8, Exposure: 1/290, ISO: 50
At night the Mate 8 returns to the Huawei P9 on a domain: color management. The photo on the P9 appears in black and white, whereas it is in color. However, the picture is much less noisy on the P9 and it also seems better defined on it.
Huawei P9, Exposure: 1/15, ISO: 3200
Huawei Mate 8, Exposure: 1/4, ISO 1250
In macro mode, the picture is similar: better contrast and details.
Black and white 100%
We also compared the P9 and Mate 8 in monochrome. P9 has such a default mode, while for Mate 8, it must go through a monochrome filter. The record is well above the P9, with, again, better contrast and more accurately.
Huawei Mate 8 P9 exceeds in many areas: definition images, color management, developed in ideal conditions, management of black and white contrast. However, the Mate 8 catches up in two areas: the focus in low light and night color management. Both smartphones are good photo even if the Huawei P9 is used to place the bar even higher. We will realize later comparative face the flagships of the moment, including the Galaxy S7, but at first glance, the P9 is not positioned to compete in this area.
