when we say mega pixel or pixel in cameras or in mobile cameras.. what actually PIXEL means?

Answer 1

Pixels are the tiny squares that make up an image. Look very closely at your screen and you'll see them. The more pixels in a certain area, the better the detail of an image. Higher resolutions on monitors give better detail because it means more pixels in a certain area.

Answer 2

Digitally dots make an image. When the number of dots are higher you get better images. So when you have mega pixels the picture quality improves and you can see a very good picture.

Answer 3

Short for Picture Element, a pixel is a single point in a graphic image. Graphics monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are so close together that they appear connected.

The number of bits used to represent each pixel determines how many colors or shades of gray can be displayed. For example, in 8-bit color mode, the color monitor uses 8 bits for each pixel, making it possible to display 2 to the 8th power (256) different colors or shades of gray.

On color monitors, each pixel is actually composed of three dots -- a red, a blue, and a green one. Ideally, the three dots should all converge at the same point, but all monitors have some convergence error that can make color pixels appear fuzzy.

The quality of a display system largely depends on its resolution, how many pixels it can display, and how many bits are used to represent each pixel. VGA systems display 640 by 480, or about 300,000 pixels. In contrast, SVGA systems display 800 by 600, or 480,000 pixels. True Color systems use 24 bits per pixel, allowing them to display more than 16 million different colors.

A pixel (short for picture element, using the common abbreviation "pix" for "picture") is a single point in a graphic image. Each such information element is not really a dot, nor a square, but an abstract sample. With care, pixels in an image can be reproduced at any size without the appearance of visible dots or squares; but in many contexts, they are reproduced as dots or squares and can be visibly distinct when not fine enough. The intensity of each pixel is variable; in color systems, each pixel has typically three or four dimensions of variability such as red, green and blue, or cyan, magenta, yellow and black.

i just searched those answers.... hope these helps

Answer 4

It indicates the resolution of the camera, the picture quality. The higher the no. of pixels, the better teh picture quality.

Answer 5

A pixel (short for picture element, using the common abbreviation "pix" for "picture") is a single point in a graphic image.the higher the pixel resolution the better the image quality.

Answer 6

pixel is formaion of electronic dots 1000 pixel is kilo pixel ,10X 1000000 pixels means one mega pixels, each memory or clip is stored in the camera has file size , such size is called pixel or kilo pixel or mega pixel

Answer 7

Pixels for digital cameras are like the grains on film for film cameras. The more there are, or the higher number, more more sensitive to light it is. This is controlled differently with digital cameras though. Everything is automatic :)

Answer 8

pixels are little dots....the more pixels the better quality of the pictures as it takes a hell lot of pixels to make up a picture
