Sensor Pixels
Similar to an array of buckets collecting rain water, digital sensors consist of an array of "pixels" collecting photons, the minute energy packets of which light consists.

" per inch" (PPI) is the more straightforward of the two terms. It describes just that: how many an image contains per inch of distance (horizontally or vertically).

Megapixels Explained
Choosing the number of megapixels a camera takes will determine overall cost and the size of the prints produced from the images. A megapixel is equal to 1 million pixels, the computer elements used to produce a digital image.

Megapixels: Calculating the True cost of Resolution
Nothing excites camera buyers more than leaps in resolution. Like it or not, the eye-catching and revenue generating headlines are about mega-pixels.

Megapixels - An Explanation of Megapixels and How They Affect Photos
Camera manufacturers are fond of advertising cameras by the number of megapixels they have. But what exactly is a megapixel and how does it affect photos?

PPI (Pixels per inch)
An indication of resolution for digital pictures taken by a camera or scanned in.

10 megapixels and up: The more advanced cameras tend to have image resolutions of 5 to 8 megapixels. Newer Digital SLRs can go up to 24 megapixels and you'd also expect their prices to go up too.

Pixels Per Inch

It's Not Just Megapixels
Image quality in a digital camera is affected by much more than how many pixels fit its sensor
By Rob Sheppard ...

Open a file from such a cheap camera in Photoshop and upsample it to 6 megapixels so it will be the same size as one of our supposedly "good" images. What will our upsampled file look like?

When comparing digital cameras and their resolutions, it pays to be aware of the effective number of pixels, as often the total number of CCD pixels is quoted as an advertising ploy.

The size of a digital camera's sensor depicts the number of that can be captured when it records the image. This is represented as "MegaPixel" or Millions of .

Pixels
A digital photo is built from a number of pixels (pixel is the short name for picture element). Pixels are small colored squares which together forms a grid pattern resulting in the final picture.

per centimeter (ppcm), per inch (PPI) or pixel density is a measurement of the resolution of devices in various contexts: typically computer displays, image scanners, and digital camera image sensors.

Pixels
A pixel is a contraction if the term PIcture ELement. Digital images are made up of small squares, just like a tile mosaic on your kitchen or bathroom wall.
