What is the need of dual rear camera in smartphones?

Dual camera system in smartphones for better photography

Using dual lens system, some  limitations of phone cameras can be overcome to an extend

Smartphone technologies are evolving much faster than anything else.Many leading manufacturers are rolling out dual camera smartphones for better better photography.Thickness of smartphone is less than 10mm and people always prefer slimmer phones.So, phone cameras are starting to reach some hard physical limits.To overcome this constraint phone companies are looking for alternative
means to keep improving.Dual camera is just one solution to overcome this constraint to an extend.
Dual cameras were first introduced in the HTC Evo 3D smartphone way back in 2011. At the time, the dual camera was used to capture 3D images to work with the 3D screen of the HTC.In 2015, Lenovo introduced a dual front camera in the Vibe S1 — it had a primary 8MP front camera and second 2MP front camera to capture better selfies. Vivo is the latest brand to launch a smartphone with dual front camera in the Vivo V5 Plus.

Need for Dual cameras in smart phones

When compared to other digital cameras phone cameras have got lot of limitations.They are listed below.
  • Limited optical zooming 
  • Limited aperture 
  • Lack of multi-focus 
  • Smaller sensor size 
To overcome above limitations phone companies have introduced dual cameras and dual lens cameras.

How Dual Camera Works in Smartphone

We can call main camera primary and other one secondary.Usually primary camera will be of higher pixels and secondary of lower pixel resolution. In a dual lens camera or dual camera setup one camera is used to take the pictures and the other one is to capture the depth of field. It is interesting to see that different phone manufacturers exploit secondary camera in different ways.Some manufacturers use it merely for collecting details about the image captured by primary camera while others use it also for capturing the image.

Advantages of Dual Lens Camera in Smartphones

Greater Depth of Field in Pictures

With dual lens setup you will get wider aperture if both cameras are working together. It allows more light to pass through the lenses to the sensor resulting in greater depth of field in the pictures. We have already seen, one lens is used to capture the image and the other one is used to get the depth of field.

Faster Focus

Dual lens camera give you faster Auto-focus (~ 0.1 seconds) which is not possible in single lens camera smartphone.


Refocusing means 'focusing the picture even after the shot has been taken'Dual camera can allow you to refocus the picture.The secondary camera helps to perform refocus functionality.

Bokeh effect

bokeh effect

You can also create the bokeh effect by blurring the out of focus parts or background of a picture. Image processing software also plays a large part in creating this effect.

Better Picture Clarity in low light conditions

Dual Camera Smartphones can takes better quality pictures in low light conditions. This is because dual lenses allow more light to pass to the sensor which results in better picture clarity in areas with low light.

Better Noise reductions and sharpness

By comparing the inputs from primary and secondary cameras special algorithms can easily detect and reduce the noise in the final output.

Disadvantages of rear/front Dual Camera Smartphones

  • Currently dual lens cameras have been designed mainly for high quality photography. Videography has not been benefited by this system so far.
  • Higher cost due to addition of hardware and software.
