Digital cameras can include features not found in film cameras, such as:
– Displaying an image on the camera screen immediately after it is registered.
– The ability to take thousands of images in a single small memory device.
– The ability to record video with sound.
– The ability to edit images or delete images, again to use the storage they occupied.
Apparatus Digital photography is a camera that takes pictures or video, or both, by recording images in a digital sensor sensitive to light. Most digital cameras measure subject distance automatically using acoustic or electronic techniques, but it is unusual to say they have a rangefinder. The resolution of a digital camera is often limited by the camera sensor (usually a CCD or sensor chip CMOS) that converts light into discrete signals, replacing the use of film in traditional photography.
Digital cameras have high power requirements and over time have become increasingly small in size, causing a constant need to develop a battery small enough to fit in the camera and yet able to power for a reasonable period of time. Digital cameras are incorporated into many devices ranging PDA and mobile phones (also called camera phones) to vehicles and even webcams. Webcams are digital cameras attached to the computer used for video conferencing or other purposes.
