Final answer:
A digital image is composed of structurally ordered areas called pixels, which contain information about color and brightness. Each pixel is assigned a specific location and color value, such as red, green, or blue. Pixels play a crucial role in determining the resolution and quality of a digital image.
Step-by-step explanation:
A digital image is composed of structurally ordered areas called pixels. These pixels are the smallest units of an image that contain information about color and brightness. Each pixel is assigned a specific location and color value, such as red, green, or blue.
For example, in a flat screen LCD television, the image is created by millions of tiny pixels, each containing red, green, or blue filters. When light passes through these pixels, the liquid crystal can control the intensity and color of the light, allowing for the display of different colors and contrasts.
Pixels play a crucial role in determining the resolution and quality of a digital image. Higher resolutions with more pixels result in sharper and more detailed images, while lower resolutions may appear pixelated or blocky.
