Digital cameras can be confusing to the new user; this need not be so if the terminology is explained. For example, what on earth are pixels? It is just a term conflating the words "Picture" and "ELement." Digital pictures are made up of tiny squares. These are like small tiles of a mosaic. This means that whilst a picture looks sharp and clear to us it is actually made up of millions of miniscule squares.

When buying a digital camera you may see a pixel count.

A line-scan camera is a camera device including a line-scan image sensor chip, and a targeting mechanism. These cameras are virtually only utilized in economic settings to capture a picture of a continuing stream of moving material. Unlike other digital cameras, line-scan cameras utilize a single spread of pixel sensors, rather than a matrix of them. Information coming from the line-scan camera has a frequency, where the camera scans a line, waits, and repeats.

A mirror less interchangeable lens camera or electronic viewfinder interchangeable lens, Micro, or Digital Interchangeable Lens system camera is a developing class of electronic cameras, intermediate between digital compacts and digital single-lens reflex cameras.

Many devices include electronic cameras built into or integrated into them. For instance, mobile phones frequently include electronic cameras which are included in their hardware; the ones that are occasionally known as camera phones. Other tiny electronic devices (particularly those utilised for communication) like PDAs, PCs regularly contain a built-in electronic camera, as do some digital camcorders
