What does the term "pixel" refer to in video technology?

The term "pixel" in video technology refers to the smallest unit of a digital image. Each pixel represents a single point in the image and contributes to the overall picture quality and detail. When combined with many other pixels, they create the full image that we see on a screen. Digital images are made up of a grid of these pixels, and the resolution of an image is determined by the number of pixels it contains in width and height. Higher pixel counts generally lead to more detailed images, as each pixel can vary in color and intensity, allowing for a broader range of visual detail in digital media.

This definition is fundamental to understanding how images are constructed and displayed in various forms of technology, such as televisions, computer monitors, and cameras. Understanding pixels also lays the foundation for discussions about resolution, image quality, and screen technologies.
