Many of our users are not aware of the multiple camera setups on their smartphone, and in this article, this might clear up their doubts and also provide them with new information.

How Do Multiple Cameras On A Smartphone Work

Primary Camera

This is the prime lens on a smartphone that usually has a focus range of f/1.5 to f/2.4; the lesser is better. It helps to capture the main subject through the camera. The videos over here can be achieved in higher framerate and also supports Optical Image Stabilization,  Electronic Image Stabilization, Slow-motion, Hyperlapse, and Panoramas.

All the other lenses present in the smartphone are dependent on the primary sensor. The main camera, which has dual camera setups are usually the secondary ones, which are of three types – Depth Sensor, Monochrome Sensor, and Telephoto lens.

Depth Sensor

The depth sensor is CMOS type sensors with an IR projector that helps to send the signals of the entire area in a 3D depth form. Generally, the OEM’s use the Duo M sensor, which is capable of capturing images of up to 2.5-meter range. This indeed helps in those portrait mode images which have a blurred background and the main object in focus.

In other terms, this sensor helps in achieving the Bokeh effect, but it doesn’t have any primary function as it is dependent on the Primary camera. Many OEMs use this as an alternative to Telephoto lenses as it is comparatively cheaper than the other.

Monochrome Sensor

Monochrome sensors are used to capture better details in an image because the primary sensors cannot differentiate the colors by itself. This helps in specifying the Red, Green, or Blue color capture in in-depth details, thus producing a compelling and vibrant picture. Here, the output pixels are combined, and the image is created.

Now the problem here arises is that due to the color array, the image quality decreases, and each pixel captures the specific color, which results in lowering the sensitivity. For that reason, the Monochrome sensor helps in combining the black and white colors and produces a full high-quality, detailed image. Monochrome also helps in night-time or at low light, where it delivers the best clarity of images. This camera sensor is used lesser on most budget-friendly smartphones due to the expensiveness of the hardware. However, you may find these multiple cameras on smartphones likes Huawei, Samsung, Xiaomi that are mid-range levels.

Conclusion

We will discuss more on multiple cameras on smartphones like Telephoto, Optical zoom, Wide-angle, and Macro, where you will be able to learn many more things.
