Boasting a 5 megapixel back-side illuminated sensor, five element lens, IR filter and ISP built right right into the iPad's A5X chip, the iSight is a marked improvement over what iPad 2 owners were forced to get their shutterbug on with. But what do all these specifications really mean? We're here to break it down for you.
Let's start with megapixels. Megapixels are the most common measurement used in digital photography. One megapixel is equal to one million pixels. The term is also used in reference to the number of image sensor elements used in a digital camera. In the simplest terms, the image sensor in a digital camera each individual image sensor in a digital camera captures the light level of a specific part of the image you're trying to capture. The most pixels you have, the more detailed your image will be. With the five megapixel camera baked into the new iPad, users can expect to shoot some pretty decent pictures, especially when you factor in the rest of the imaging technology the tablet employs.
When Apple talks about there being five lens elements in the new iPad's camera, what they're really saying is that in reality, the lens actually consists of five smaller lenses all arranged along the same axis. This helps to insure that your pictures will be free of optical imperfections such as dust, distorted colors and lens flare.
What about ISP? That's digital camera shorthand for Image Signal Processor. ISPs use a number of complex algorithms to translate what your camera's fancy megapixels and lens elements have captured and turn the raw image data into photograph that approximate what would be seen by the naked eye. It's magic! The fact that the new iPad's ISP is cooked right into the tablet's powerful A5X processor means that users will be able to take photos with their iPad faster and more accurately than ever before,
Now that's an upgrade anyone should be able to appreciate.
