Question

What pixel mean in digital camera?

Answer 1

Every digital image consists of a fundamental small-scale descriptor: THE PIXEL, invented by combining the words "PICture ELement."  Just as how pointillist artwork uses a series of paint blotches, millions of pixels can also combine to create a detailed and seemingly continuous image.

Each pixel contains a series of numbers which describe its color or intensity.  The precision to which a pixel can specify color is called its bit or color depth.  The more pixels your image contains, the more detail it has the ability to describe.  

Bit it gets ridiculous to buy a camera over 5 or 6 mega pixels unless your planned on printing out posters.

Answer 2

since you asked in the camcorder section, there are two meanings to pixel. first is the number of actual digital picture elements in the CCD array that makes the initial picture capture. second is the pixel definition recorded in the data stream. for miniDV, each picture frame is composed of 480 by 720 pixels. for HDV, the frame size is 1080 by 1440. Because the CCD array may be configured differently, the pixels recorded on tape often is an interpolation of the actual capture.

the pixel arrangement for television broadcast and TV sets is different yet, and for still photos, the pixel count can be most any size.
