A digital image is a visual representation of information in a digital format. It is created by converting analog data, such as photographs or drawings, into electronic signals that can be stored and manipulated by computers. It consists of a grid of picture elements, known as pixels, with each pixel representing a specific color and intensity value.
Digital images are composed of a fixed number of pixels, which determines their resolution. The higher the resolution, the greater the number of pixels and the more detailed the image appears. Digital images can be two-dimensional, such as photographs or graphics, or three-dimensional, such as computer-generated models.
These images are commonly used in various fields like photography, art, advertising, and web design. They can be captured using digital cameras, scanners, or created through digital graphics software. Digital images offer numerous advantages over their traditional analog counterparts, such as ease of storage, editing, and sharing.
These images are typically stored as files in various formats, such as JPEG, PNG, or GIF, which determine the level of compression and the quality of the image. They can be displayed on digital screens or printed on physical media using printers or other printing devices.
Overall, digital images have revolutionized the way visual information is created, stored, and shared. Their versatility and flexibility make them an integral part of our digital world, influencing communication, entertainment, and many other aspects of modern life.
