Types of Digital Images and Digital Video Devices

Comparing Digital and Analog Video Equipment Capturing Digital Images with a Digital Camcorder

What are the differences between the types of digital images and digital video devices?

The first step in creating your digital images is deciding what type of device you need to capture the image (or action). "Capturing" is a term often used interchangeably with "acquiring". Both terms are used to describe the process of using a digital device to create a digital copy of an analog image. The charts below list the types of devices and what can be used to capture each type of digital image, in order of image quality. There are two types of digital devices: hand-held and desktop (which must be connected to a computer), and three general types of digital images: still pictures, motion video (static) and motion video (web-based).

Still pictures can be described as "digital photographs". When you see a picture on the Internet (such as in our navigation bar, at right), you are looking at still pictures, which have been saved in a number of different ways (called "file formats").

Static motion video describes video images which are recorded and saved as a file for playback. Examples of standard video are home movies or video clips, movie trailers and on-line movies on the Internet.

Web-based motion video describes video images which are captured in close to real time and transmitted over an Internet connection using specialized software. Examples of web-based motion video are video conferencing and webcams.
  • Video conferencing: on-line meetings with both audio and video functions.
  • Webcam: a web page which displays images or live video from a computer-based camera.
Handheld devices: Desktop devices:
Still pictures can be captured by:
  • Taking pictures with a digital camera.
  • Converting existing photographs or images with a flatbed scanner.
  • Taking pictures with a digital camcorder.
  • Taking pictures with a computer-based camera.
Motion video can be captured by:
  • Filming with a digital camcorder.
  • Using the "Burst" feature of a digital camera to capture short (8-12 frame) motion video.
  • Using a computer-based camera.
Web-based video can be captured by:
  • Using a computer-based camera.
  • Using a dual-mode digital camera.
