For example, in LCD screens the three main colors are sampled at different locations of a staggered grid, while digital color cameras use a more regular grid. Pixels are uniformly arranged in a two-dimensional grid, although some different sampling patterns are available. Because of that, individual pixels may become visible, leading to a blocky and chunky image defined as “pixelated”. It will equal the size of the dot pitch if the display is set to its maximum resolution, and will be larger if the resolution is lower since each pixel will use more dots. The physical size of a pixel varies, depending on the resolution of the display. For example, a 2.1 megapixels picture contains 2,073,600 pixels since it has a resolution of 1920 x 1080.
The pixel resolution spread also determines the quality of display more pixels per inch of monitor screen yields better image results.
For example, a computer with a display resolution of 1280 x 768 will produce a maximum of 98,3040 pixels on a display screen. Pixels are the basic building blocks of a digital image or display and are created using geometric coordinates.ĭepending 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. A pixel is represented by a dot or square on a computer monitor display screen.
