Many digital cameras are capable of recording video in addition to taking photos. The picture is of a Casio QV-R62 with 6.0 megapixel resolution, an example of a typical digital camera.

Note: A camera that is always connected to your computer with no storage could also be referred to as a digital camera. However, it is more appropriate to refer to this device as a webcam.

Note: A digital camera may be considered both an input and output device (sometimes referred to as an I/O device) as it can both take pictures (input) and send them to your computer (output).

What are the advantages to using a digital camera?

Below are key advantages that make digital cameras a popular choice when compared to film cameras.

LCD screen

The rear-mounted LCD screen on a digital camera allows users to see their photos and videos immediately after they have been taken. The LCD screen can also make it easier to frame your pictures.


A digital camera can store thousands of pictures, instead of only up to 36 pictures.

Picture development

Digital camera pictures can be developed just like on a standard camera, but you can pick and choose which pictures to develop instead of having to do the whole roll of film.


Because a digital camera does not need a place for film (not an SLR), it takes up far less space and can easily be carried in your pocket or purse.

History of the digital camera

Although the idea for a digital camera originated in 1961, the technology to create one didn't exist. The first digital camera was invented in 1975 by Steven Sasson, an engineer at Eastman Kodak. It primarily used a charge coupled device, a type of image sensor, but originally used a camera tube for image capture. That functionality was later digitized by Kodak. The first digital cameras were used by the military and for scientific purposes. Medical businesses and News reporting companies began to use digital cameras a few years later.

Digital cameras did not become common consumer electronic devices until the mid 1990s. By the mid 2000s, digital cameras mostly replaced film cameras as the camera of choice by consumers.
