What is pixel?

[vexpertise]

A pixel is represented by a dot or square on a computer monitor display screen. Pixels are the basic building blocks of a digital image or display and are created using geometric coordinates. Depending on the graphics card and display monitor, the quantity, size and color combination of pixels varies and is measured in terms of the display resolution.

For example, a computer with a display resolution of 1280 x 768 will produce a maximum of 98,3040 pixels on a display screen. Each pixel has a unique logical address, a size of eight bits or more and, in most high-end display devices, the ability to project millions of different colors.
The pixel resolution spread also determines the quality of display; more pixels per inch of monitor screen yields better image results.

The pixel is the basic unit of programmable color on a computer display or in a computer image. Think of it as a logical - rather than a physical - unit. The physical size of a pixel depends on how you've set the resolution for the display screen. If you've set the display to its maximum resolution, the physical size of a pixel will equal the physical size of the dot size of the display. If, however, you've set the resolution to something less than the maximum resolution, a pixel will be larger than the physical size of the screen's dot.

Pixel is a minute area of illumination on a display screen, one of many from which an image is composed."the camera scans photographs and encodes the image into pixel

A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device.

A pixel (short for "picture element") is a single dot in the matrix of colored dots that make up the image we see with our eyes. A digital sensor uses a matrix of photo-sites, or light wells, each of which counts the number of photons hitting it.

The pixel (picture element) is smallest unit of image. By this we measure the image size. It is totally depends upon the resolution of the screen or canvas size. It is term of graphic user interface in computer science.

Piexel is a picture element is a basic unit of programmable color on a computer image. A piexel is the smallest unit of a digital image that can be displayed and represented on a digital display service.

The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. Every single dot on screen and they are small squares generally

Pixel is the smallest square element of an image. There may be thousands of pixels, that together make up any image. If we zoom the image to the extent then we are able to see some of the pixels. Dimensions of any image can be measured using pixel area. Pixels are often represented using squares.
