Quad Camera on the rear of the phone, its benefits and more

Camera performance is the biggest part of the new generation of smartphones. Phone creators consistently work to enhance camera quality. Similarly, the phone camera is an important factor, users consider before buying the phone. That’s the reason why manufacturers are zealous to add Quad-Camera. Subsequently, major brands have started setting up the Quad-Camera mechanism in their smartphones.

After the triple camera, phones are being launched with a quad-camera setup comprising different utilities’ lenses on the phone’s back. One of the top Smartphone manufacturers, Samsung, launched Galaxy A9 with a Quad camera on the rear. With this launch, Samsung has become the first brand to bring a world-first quad-camera phone.

In the growing Quad-Camera trend, more smartphone companies are in the race to offer multiple sensors. But there are some questions such as, ‘What’s the quad-camera meaning’ and ‘What are the different lenses in the Quad-Camera? Here, you will get all these answers. So, let’s go ahead!

 

What is Quad Camera?

The Quad-Camera simply means four cameras on the rear of a phone. Just as single, dual and triple means one, two and three cameras respectively, the Quad meaning four.

Earlier, a set of dual (two) rear cameras and dual (two) selfie cameras on a phone considered quad-cameras. But recently, things have changed. Now, four-camera on the rear of the phone consider as Quad-Camera.

What are the different lenses in the Quad Camera setup?

There are different lenses or sensors in the quad-camera setup. Different brands use a different combination of lenses in their quad-camera setup. Here are some-

Type -1 

  • Main camera lens
  • Telephoto lens
  • Ultra Wide Angle lens
  • Depth sensor

Type -2

  • Main camera lens
  • Monochrome lens
  • Ultra Wide Angle lens
  • Depth sensor

Type -3

  • Ultra Wide Angle lens
  • Macro Lens
  • Depth sensor

The megapixels and aperture also differ in different phones.

 

How Quad Camera works?

Every lens in the camera mechanism has different functions, capabilities, and work. In the same way, each sensor plays its role for different requirements during a click.

The standard or Main Lens helps to capture an image as usual. This sensor provides a detailed photograph in bright and low light however, the quality of snap is quite related to its megapixels. Brands are offering 24, 48 or 64-megapixels in main sensors. Notably, Realme XT has a 64-megapixel main lens.

With a Telephoto Lens, the zoom has gone digital. The lens usually offers 2x zoom for your photos (Huawei mate 20 Pro’s lens lets 3x zoom). Apple iPhone 7 Plus in 2016, offered a telephoto lens. Instead of adding optical zoom to the main camera, manufacturers started adding a telephoto lens.

An Ultra-Wide Angle Lens gives the ability to the camera to capture wide-angle snaps. A wide-angle lens provides batter ‘Field of View’ to make wider your capture area. Nowadays, the latest phones with quad-camera are offering a 120-degree field of view.

Depth Sensor estimates the depth of the background comparing the subject. Using the depth-sensing technique, your camera lets better Portrait and Bokeh. The sensor allows you to easily focus on the subject while blurring the background slightly.

Some manufacturers also offer Monochrome Sensor as the fourth lens. The monochrome lens takes a black and white image and combines it with the RGB image captured by the main camera. This process helps to place more detail to the image.

Also, a Macro Lens is found in a few phones as a fourth lens, which allows the camera to capture a close image of a subject. The lens also provides the ability to capture a clear and detailed image of a small subject at a very near distance.

 

What is the need of the Quad Camera?

The quad-camera trend is going on. But, do we need a Quad camera in smartphones? Further, is a Quad-camera better than a triple camera?

The answer is simple, adding more lenses in the camera setup gives additional photographic abilities to your phone’s camera. In DSLR cameras you get a professional quality image. But on a phone, the bulky lenses can’t be attached. Similarly, there’s a size limit of the lens in phones. So, an alternative, manufacturers integrate multiple lenses for distinct features.

As you know, the phone’s camera performance has become one of the key factors to influence the buying decision of a phone buyer. That’s why phone manufacturers working to enhance camera image quality, which is now near to DSLR.

The main sensor with the ultra-wide lens or telephoto lens helps to get a professional quality image in different light conditions. Whereas, using a portrait or depth sensor, you’ll get a better portrait and bokeh. Other additional lenses such as a monochrome lens and a Macro lens adds better details in your snaps.

What are the benefits of the Quad Camera?

Each lens in the multi-camera setup has a different function and using them in a single phone has many advantages during an image click. What are the advantages of Quad camera, let’s see in-depth-

  1. High-resolution image: A higher resolution lens gives a good quality image that can be printed, cropped or zoom while re-storing the same quality. In some cases, the additional camera also collects additional detail and information and combines it with the standard camera results. It delivers a better image than a single camera would capture.
  2. Crisp and detailed shots, even from a distance: A telephoto lens offers optical zoom, which is to get closer to the subject and capture it without compromising the image quality. The telephoto lens offers 2x, or sometimes 3x zoom results a distant snap with crisp and detailed information in your picture.
  3. The clear and bright image in different light conditions: An additional monochrome sensor helps to get a bright image in low light situations.  When the output of the monochrome lens blends with the standard camera image then it provides a professional quality detailed snap with the required brightness and clarity.
  4. Wider snaps and more field of view: Ultra-wide lens along with the standard lens provides more ‘field of view’ that simply means a wider image. The lens usually offers a 120-degree ‘field of view’ that helps you to capture a bigger viewing area then a single lens would do.
  5. Depth detection, better portrait with the focused subject: Depth sensor with the combination of different lenses creates better portraits for you. The camera detects the depth of background and equally focuses on the subject. Accordingly, it lets you get a clear subject while automatically making the background blurred.

Quad Camera phones

In the quad-camera trend, phone brands have initiated containing a camera grid with four lenses. Galaxy A9 is the world’s first phone, which was launched in late 2018, has the quad-camera mechanism.

The trend grew in 2019, and companies such as Samsung, Huawei, Lenovo, Honor, Redmi, Realme, and Oppo brought quad-camera in their smartphones.

In the same way, some latest and upcoming models such as Samsung Galaxy S10 5G, Huawei P30 Pro, Realme XT, Redmi Note 8, Oppo Reno 2 series coming with four cameras on the rear.

 

The outline

Manufacturers are offering Quad-camera, and of course, users are also liking it. As a result, we sense a rise in the popularity of quad-camera in phones. The main thought behind putting multiple cameras is to enhance camera performance so that you get better image quality and features, somewhere close to DSLR output. Also, this whole integration makes possible the use of Augmented Reality, 3D, and some special effects into your picture.

However, there are a few challenges. The phone requires a higher processing power to process an image using multiple lenses. The second major challenge is the phone size because you always expect a thinner phone after all.

The new camera innovations are also opening the door for new possibilities for further enhancements. The day may not be so far when we would usually see Penta camera and Hexa cameras on the rear of the smartphone.
