Learn more about ASUS SuperPixel™ Camera
ASUS SuperPixel™ Camera — ZenFone 4 Pro offers 8x light sensitivity than other smartphones thanks to its new ASUS SuperPixel™ main camera that allows users to take extremely fast and clear photos at night or in low-light environments. The SuperPixel™ Camera consists of following components:
Large F1.7 lens aperture
The large aperture allows for more light to enter the sensor compared to other smartphone cameras.
F2.2 aperture
F1.8 aperture
(49% more light than F2.2)
ZenFone 4 Pro
F1.7 aperture
(67% more light than F2.2)
Large 1.4µm pixel size
Larger pixels increase the camera’s sensitivity to light and decrease the graininess of resulting photos — especially those shot in low-light environments. ZenFone 4 Pro uses the Sony IMX362 sensor with 1.4µm pixels and a 1/2.55-inch sensor size, which are among the largest of any smartphone camera sensor and make ZenFone 4 Pro excellent for low-light photography.

ASUS SuperPixel™ Engine
An exclusive image processor boosts sensor light sensitivity by up to four times by intelligently controlling ISO levels while shooting and performing noise removal in post-shot processing. Along with Qualcomm® Spectra™ image signal processing, two dedicated image processors even bring photography experience to next level, providing smoother zooming, faster autofocus, and photos with gorgeous, true-to-life colors.
4-Stop OIS
Four stops optical image stabilization (OIS) allows the camera lens to move in eight directions to neutralize camera shake caused by unsteady hands, resulting in consistently sharp photos. OIS also enables you to shoot handheld using shutter speeds that are four stops slower than traditional cameras, letting you shoot gorgeously, blur-free photos at night and in low-light situations.
PixelMaster Technology
Capture reality, fast and steady
The camera on ZenFone 4 Pro lets you capture the world as you see it by TriTech+™ technology. With ultrafast, dual pixel phase-detection, subject-tracking, and laser auto-focus, ZenFone 4 Pro accurately focuses in just 0.03 seconds and keeps moving subjects in focus to ensure clear and detailed photos. Together with both optical and electronic image stabilization for blur-free photos and videos, an RGB color-correction sensor for true-to-life colors, and true 4K UHD video recording, the camera on ZenFone 4 Pro goes above and beyond other smartphones.

Each pixel on ZenFone 4 Pro's image sensor is divided into two phase-detection areas that detect subject movement by analyzing variations between light rays hitting the two sensors. With more than 12 million pixels on the sensor performing this task in concert, ZenFone 4 Pro’s phase-detection auto-focus system is able to achieve ultrafast focus, even in low light conditions.

ZenFone 4 Pro’s camera cleverly tracks moving subjects, so they will never be out of focus. Subject tracking is enabled by default for both still images and videos.
Blur-free photos and steady videos
ZenFone 4 Pro’s camera has innovative four-axis optical image stabilization (OIS) that allows the lens to move in eight directions to compensate for hand and motion shake, keeping the lens steady to ensure sharp, blur-free photos. OIS also improves camera performance in low-light conditions, letting it use shutter speeds up to four stops slower than normally possible for sharper, brighter shots with lower noise. For video shooting, ZenFone 4 Pro employs electronic image stabilization (EIS) that uses smart software algorithms to detect shakes and sharp movement along three axes and automatically apply compensation to ensure smooth and steady videos.
