We see that the phones have become very expansive these days in which a good camera is also being given, it is getting a lot of megapixels like 64 megapixels 102 megapixels in the small sensor itself and for the same money a DSLR or Mirrorless camera comes In which only few megapixels can be found. here will also give details on whether the size of a camera’s sensor really matters or should we keep in mind only the megapixels.
Another question you would like to answer, when we are getting such a good photo sensor of such a small smartphone, why do we need such an expensive dedicated camera whose sensor size is so big and the megapixels are less.
Camera Sensor Sizes Explained : How does Sensor size affect image quality
Smartphone users and a lot of photographers think that more megapixels gives better photo quality whereas more megapixels means bigger photo, it doesn’t mean that the photo is clean and its quality is good, it just increases the image size.
If we come to the main point, which is the sensor size, then smartphones usually come with a sensor of 1/2.55 inch while flagship smartphones are paired with some larger size 1/.33 inch sensor, however now The biggest sensor till date was the 1/1.2 inch sensor in Nokia’s PureView 808 launched in 2012. The sensor size in DSLR camera is above 1 inch which can be more than 5 to 6 times than that of phone, however sensor size in high-end digital camera is also available in much large size which will not be appropriate to compare with smartphone camera.
The Photo quality depends on certain elements like sensor and lens material file type. Photo sensor is made by receiving light from the sensor, only the light coming into the sensor makes a difference to the photo, if the sensor is bigger then it will accept more light and smaller sensor will receive less light than it.
The main effect of this will be that the larger sensor will take less time to expose the pictures well, And the smaller sensor will take more time, as well as the it will develop more noise and in the larger sensor because the light is coming more, thumping Images are captured even at night and the flicker noise is also less. There’s another feature that doesn’t make much of an impact with smaller sensors, which is greater tonal accuracy and better natural color in the pictures.
If you want a good background blur in the picture, then the it helps you a lot in this, due to the big sensor, there is a good bokeh effect in the photo. And it is also another strength of a large sensor that when it is wide size, the crop factor decreases, due to which we get more field of view than smaller sensors from the same distance, we cover more area in the image.

In the end, if we come to the conclusion, the way the number of megapixels in smart phones is increasing continuously, it does not mean that the picture quality will be good. It depends on the size of the sensor, and the technology used in manufacturing the sensor.
