What are pixels in image?

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software.

What is the size of a pixel?

A pixel is a unit of measurement commonly used in graphic and web design. We can abbreviate it using "px". You can convert mm to pixels – the length of a pixel is 0.26 mm or 0.0104 inches (provided that the resolution equals 96).

How do pixels work?

Each pixel is made up of a red, green and blue subpixel that lights up at different intensities to create different colors. The specific color information that a pixel describes is some blend of three components of the color spectrum -- RGB.
