Many companies are always talking about the next model with more megapixels than the one came before it. The best example, 41 megapixel Nokia 808 pure view piled on the megapixel. If you bought a camera with 8 megapixel a few years ago, you wish you could get a new one that gets 16.
But does it really means anything ???? Come on, lets find out:
Can u judge a camera's quality , only by looking megapixel count . Many smartphone user thinks increase in megapixel means better image quality. BUT THIS IS COMPLETELY FALSE .
Sometimes super high megapixel camera perform worse than low megapixel models . Excluding megapixel, many factors work in combined way which effect the quality of the image.
BSI sensor is consider to be good but latest CMOS sensor sometimes better than BSI sensor.
So, there is a question mark on this.
It is the most important ingredient in the optical system because that’s the part that captures the light. In general, the larger the sensor , the larger your pixels ,and the larger your pixels, the more light you can collect. The more light you can catch , the better your image can be.
For example :- 1/2.3” (inches) is better than 1/3” (inches)
1/2.3” > 1/2.6” > 1/3”
Greater the sensor means best low light performance.
Aperture is the opening of camera , which can be adjusted to control the amount of light reaching the film or image sensor.
For example:- f/1.8 is better than f/2.2.
f/1.8 > f/2.0 > f/2.2
It also controls the low light performance.
OIS (Optical Image Stabilizes):
OIS (Optical Image Stabilizes) is a mechanism used in a still camera or video camera that stabilizes the recorded image by varying the optical path to the sensor.
Some smartphone cameras with optical image stabilization.
1- iPhone 6 Plus
2- LG G3
3- Samsung Galaxy Note 4.
1. Dual Pixel. - BEST
2. Laser Af + PDAF ( Phase Detection Auto Focus ) -BETTER
1. Single toned LED flash – Only one yellow color LED flash
2. Double LED flash - Two yellow color LED flash for double power
3. Double toned LED flash- Two different color LED flash ( one is for warm other is for cold).
If the hardware of a camera is good, but the image processing is bad, then it ruins the photo but if the hardware of the camera is average, but the image processing is good, then it will develop DSLR type photo J.
For example :- SONY PHONES- Best hardware ( Self made ) but processing is worse Hence output is not good. Whereas iPHONES – Average hardware but best image processing,Hence output is good.
Never scrap Pixel count when weighing smartphone camera specs against others , but when it comes to all the hardware & software (image processing) that create a great photo , the megapixel count alone just isn’t enough.
