A warm welcome to everyone out there we are constantly trying to give our readers some new cool stuffs. In this blog post we just try to cover how the higher resolution cameras works that you should know while you are going to buy a camera centric smartphone.

Everyone has their own priority while gong for a smartphone some can buy a smartphone for the performance (PROCESSORS), some for looks, some for futuristic trends (5G), while others for the optics.

If you are in the latter case this article is for you guys. Kindly share this article with your fellow mates. Let’s dig this out 

Megapixels is nothing but how many pixels are packed or arranged in the array. Usually it is indicated as MP in the retail mobile unit box such as 12MP,16MP,48MP and up to 192 MP camera. It doesn’t mean that higher the MP count higher the image resolution. Some manufacturers such as apple and google are able to produce some spectacular images only with their 12 MP camera itself.

How they could able to do such things?

It is not a rocket science as mentioned above the quality of the image is not only depends on the MP itself, it is influenced by some other factors we will go through it below.

Before that how the manufacturers can able to implement 48MP, 64MP cameras nowadays in the budget segment.

Here comes an interesting term called ‘pixel binning’


          Pixels are binned (right side) to provide sharper images 

The name itself explains that a single pixel is combined and produce even more sharper images. A pixel binning array is just placed besides the sensor.

The pixel binning array may be quad (four pixels combined) binning or nona or nano binning (nine pixels combined) array.

In short just consider a camera 12 MP sensor.

The 12 MP sensor is just placed behind the quad pixel binning array that is 12MP* 4 and thus the resultant output is 48MP and in similar fashion if a nano pixel binning array is placed 12*9 and thus the resultant output is 108 MP.

For 64 MP

A 16MP sensor is just placed behind the quad binning and Nano binning array and the resultant output is 64MP and 144MP respectively

Aperture of the camera: 

Aperture is nothing but how wide the diaphragm opens out and captures or intake the lights. It is technically calibrated as f/1.0, f/2.0 and so on. In this scenario lower the aperture number higher the quantum of light it takes inside. For example two sensors have f/1.8 and f/1.7, the sensor with aperture f/1.7 capture even more amount of light and thus it improves the image quality especially in the night photography scenarios.

OIS AND EIS of a camera:




OIS (Optical image stabilization) is a hardware phenomenon in which the sensor of the camera is paired with optically stabilized lens.

Practical use: Eliminates the blurry images while capturing the moving objects and further it improves the quality of the night images.

EIS (Electronic Image Stabilization)

It is an implemented through the software and it highly eliminates the shakes and jittery video footage.

OIS is primarily for photos and EIS if for videos.

ISP (Image Signal Processing):

Image signal processing is an integrated entity of the smartphone processors and even in the cameras it further fine tunes the quality of the image. Brands such as oppo has their own Image signal processing called Maritime image signal processing so that it was easier for them to fine tune the output of the images even in the development of the prototypes.

In the same case apple and google also have their own chipset bionic and tensor integrated with their own Image Signal Processing.

Brand of the sensor:

In android point of view Samsung and Sony are two competitors producing the smartphone sensors. In our point of view both Samsung and Sony sensors are good enough in their own ways but we recommend to choose mobile phones with Sony sensors. Even in some Samsung smartphones such as Samsung M51 they use the Sony IMX 682 sensor it is comparatively good in terms of HDR (High Dynamic Range) of the image.

HDR (High Dynamic Range) is the nothing but how much quantum of details and sharpness that a sensor can able to collect from the darkest and brightest part of a particular image.

HDR mode works in a fashion that it combines 3 images into one normal image one from darker area another one from light area and interpolates one other and gives super rich image.

The image processing of the chipset (processors) determines the quality of the photography to a considerable extent it is fairly advisable to buy a smartphone Qualcommsnapdragon SOC’s than Mediatek SOC’s. But nowadays the Image signal processing is very much improved in Mediatek so it is not much of a different difference.

These are some of the basic things that you need to remember while choosing a camera centric smartphone. If you end up liking this article share this one with you fellow mates.
