Question

What is meant by the word pixel?

Answer 1

Pixel:

the smallest discrete component of an image or picture on a CRT screen (usually a colored dot)

Answer 2

A pixel is the smallest unit that can be addressed by your monitor (ie. it can either be red green or blue)  A collection of pixels can form another color.

Answer 3

In digital imaging, a pixel (picture element) is the smallest piece of information in an image. Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots, squares, or rectangles. Each pixel is a sample of an original image, where more samples typically provide a more accurate representation of the original. The intensity of each pixel is variable; in color systems, each pixel has typically three or four components such as red, green, and blue, or cyan, magenta, yellow, and black.

The word pixel is based on a contraction of pix (for "pictures") and el (for "element"); similar formations with el for "element" include voxel, luxel, and texel.

The word pixel was first published in 1965 by Frederic C. Billingsley of JPL, to describe the picture elements of video images from space probes to the moon and Mars; but he did not coin the term himself, and the person he got it from (Keith E. McFarland at the Link Division of General Precision in Palo Alto) does not know where he got it, but says it was "in use at the time" (circa 1963).

The word is a combination of picture and element, via pix. Pix was first coined in 1932 in a Variety magazine headline, as an abbreviation for the word pictures, in reference to movies; by 1938 pix was being used in reference to still pictures by photojournalists.

The concept of a picture element dates to the earliest days of television, for example as Bildpunkt (the German word for pixel, literally picture point) in the 1888 German patent of Paul Nipkow. According to various etymologies, the earliest publication of the term picture element itself was in Wireless World magazine in 1927,[4]though it had been used earlier in various U.S. patents filed as early as 1911.

Answer 4

what he said. It's the smallest particle of an image. the more the pixels, the better the quality of the image  

Answer 5

Pixel is an image element. Pixel in digital imaging means the smallest piece of information in an image. well, it's usually arrange in a regular 2-dimensional grid, and are often represented using dots, squares, or rectangles. each pixel has typically three or four components such as red, green, and blue, or cyan, magenta, yellow, and black.

Answer 6

Pixel : Computers, Television. the smallest element of an image that can be individually processed in a video  

Answer 7

ahah

Answer 8

a pixel is a unit of measurement that's square in shape.

they're most commonly used as pixels per inch or dots per inch.

if you have 5 pixels per inch you have 5 pixels x 5 pixels making up 1 square inch.

if you have 500 pixels per inch you have 500 pixels x 500 pixels making up 1 square inch.

the more PPI you have, the better quality of an image you will have.

Answer 9

One pixel refers to a group of three phosphors- red, green, and blue. There are several thousand of these on a typical display screen. If enlarged, a raster pixel would resemble a perfect square, all one color.
