do Megapixles Matter?
Tuesday, March 10th, 2009How many times have you seen mobile phone companies boast about the number of megapixels in the camera of their latest model? How many times have you had to suffer a friend mocking you for having a lesser-megapixel camera phone than him? Many times, I am sure.
Sony Ericsson recently revealed a soon-to-be-launched 12 MP-camera phone code-named Idou. They already have phones with 8 MP cameras that they proudly advertise. 8 MP! Wow! That must be so awesome huh? “I can’t even image the quality of photos that the phone will click,” you think. But hold on. Does the number of megapixels in a camera really matter that much? Is the hype surrounding high-megapixel phones justified? Or is it just an advertising gimmick? Do phones with more megapixels really click better pics?
Ok, that pic is funny, no doubt! But it is also true. More megapixles don’t always get you better pics. Read on…
Let’s first find out what the image quality of a digital camera really depends on.
The image quality of any digital camera depends mainly on two things:
1. the quality and size of the sensor
2. the number of megapixels
Simply speaking, a sensor in a digital camera is a device that converts optical signals to electrical impulses. Yes, I know that sounds complicated, but bear with me here. I simply mean to say that “image” that you are going to capture gets converted into electrical signals. That’s enough knowledge for the moment.
Now, the bigger a sensor is, the more sensitive it is to light. Bigger sensors also improve the sharpness of the image.
Phone manufacturers, of course, are trying to make their phones as small as possible. This makes it impossible to fit a good sized sensor inside. As a result, image quality suffers, especially in low light.
The number of megapixels, on the other hand, only help in improving the overall size of the image. Pixels, as you know, are the smallest part of an image. Those tiny little squares that everyone keeps talking about. 1 megapixel equals 1 million pixels! So the more megapixels you have, the bigger your image is.
There is a lot more to be said on this, though. Read the complete article HERE

megapixels matter a lot !!!!!
hi Abhijeet! thanks for reading
yea i guess you are right…megapixels do matter a lot, but as this article clearly shows, the number of megapixels alone do not guarantee a good image. there is a lot more that goes into clicking a good photograph.
have fun with your camera…..
There’s a new smart phone out that boast about having a 5 megapixel camera built into it. I think the cost is about $699.
Do you think a cell phone will ever be able to a decent camera? Is the new technology out nowadays have the ability to make the sensors small enough to fit in a cell phone?
cheers
the technology is definitely improving. but as phone cameras get better, so do digital cameras. it is going to be very difficult for phones cameras to catch up with their digital counterparts.
