What is pixel?

What Does pixel Mean

The concept of pixel has its origin in the English word pixel and arose as an acronym between the terms pix (colloquial expression that refers to picture , “image” ) and element (translated into Spanish as “element” ). The notion is used in the computer world to indicate the smallest homogeneous surface that is part of an image .

The pixel, therefore, can be defined as the smallest of the homogeneous color units that make up a digital-type image. By enlarging one of these images through a zoom , it is possible to observe the pixels that allow the creation of the image. They appear to the eye as small squares or rectangles in white, black or shades of gray.

The bitmaps include pixels that are coded by a group of bits of given length. The encoding of the pixel will determine the number of color variations the image can display.
True color images are known as those that use three bytes to establish a color and that, in total, provide 16,777,216 color options .
The transformation of the numerical data stored by a pixel into a color requires knowledge of depth and brightness, but also of the color model to be used. The most common model is RGB ( Red-Green-Blue ), which creates colors from the combination of red, green and blue. Monitors and scanners for computers typically use the RGB model .
In addition to all the above, we cannot ignore the fact that the term we are analyzing is also part of a very specific expression called a dead pixel. With it what comes is to describe or define all that pixel that does not work as it should in what is, for example, an LCD screen.
In the same way, it must be made clear that there is also a so-called stuck pixel, which is one that is characterized by having what is a solid color, be it red or blue or green. And all this without forgetting the hot pixel that is the white one that is always on.
It is important to underline the fundamental or special role that pixels are playing in the world of animation. So much so that there has been the creation of a new type of art that is known by the name of Pixel Art. What defines this discipline is that it consists of editing images from a computer, and more specifically doing use of a series of very specific computer programs.
In addition, in this type of art we find two fundamental elements or pillars: the isometric style, which is the one with which three-dimensional effects are achieved, and the non-isometric style, which is one that is defined by being anyone who is not framed within from the previous category.
It should be noted that one megapixel is equivalent to one million pixels. This is the unit used to indicate the resolution of a digital camera for images.
