| Definition | Pixel, an abbreviation of Picture Element, is the smallest controllable element of a picture represented on a screen. |
| Function | Each pixel stores color information for an image and collectively forms the complete image. |
| Composition | A pixel is typically composed of red, green, and blue sub-pixels. The combination of these defines the pixel’s color. |
| Resolution | The number of pixels in an image or a screen defines its resolution. Higher pixel count means higher resolution and more detailed image quality. |
| Pixel Density | It is measured in pixels per inch (PPI). It indicates the display quality. Higher PPI means a clearer and less pixelated image. |
| Pixel Bit Depth | It refers to the color information stored in each pixel. A higher bit depth allows for a greater range of colors. |
| Pixels in Digital Photography | In digital photography, pixels are used to capture and represent the digital image. The photo’s quality and clarity are proportional to its pixel count. |
| Pixel Art | It’s a style of digital art where images are created using tiny, square-shaped pixels. It harks back to the early days of computer graphics. |
