Techopedia Explains Digital Camera

Digital cameras are integrated with a wide range of digital devices, ranging from personal digital assistants (PDA) and mobile phones to the Hubble and Webb Space Telescopes. Digital photography is adaptable and compatible with email, CD/DVD, TV and computer monitors, the Web and may be stored on a PC. Some digital cameras have a built-in GPS receiver, which is used to produce geotagged photographs.

Digital photography’s key advantage is immediate video and image viewability. Image editing software is used for cropping, recoloring, contrast/imperfection adjustment and combining one or more images.

Digital cameras come in an array of sizes, features and prices, including the following:

• Compact digital camera: Portable, easy to use and small with limited picture quality. Built-in low-power flash. Images are usually stored as JPEG files. Also known as a point-and-shoot camera.
• Digital single lens reflex camera (DSLR): Design is based on the single lens reflex camera. Exclusive viewing system that uses a mirror to reflect light from the lens via an optical viewfinder.
• Bridge camera: Shares some DSLR advanced features. Uses a fixed lens with a small sensor – similar to compact digital cameras. Uses live preview for image framing.
• Mirrorless interchangeable lens camera (MILC): Combines superior quality sensors with DSLR lenses. Introduced in 2008, the MILC is simple and compact because of its ergonomic design.
• Line scan camera system: Supports focusing mechanisms and usually contains a line scan sensor chip. Used by industrial applications to capture moving material images.
• Integrated camera: Built into multiple digital devices, including mobile phones, PDAs and laptops.
