Digital cameras can be classified into following categories based on their specifications:

1. Compact Digital Cameras
   This type of cameras are small sized and easy to carry. Some of these are smaller than other compact cameras and are termed as Subcompacts or Ultra-compacts. These cameras as have small size so modern features and picture qualities are missing to great extent with them. The images formed by such cameras is stored as Lossy Compression. Compact cameras are more in casual use. In nearly every compact camera the photo is framed using the live preview. These cameras are capable of macro focusing but in cases they have the ability to zoom then the range is usually less than Bridge and DSLRs.                       
2. Professional Modular digital camera system
   This type of digital camera includes professional equipment. These cameras are capable of capturing minor details which could be enlarged up to 35mm.  PMDCS are usually used commercially. They can also be converted to film or digital by changing the rear part of the equipment. The commonly known brands for these cameras are Hasselblad and Mamiya are very expensive for common use.
3. Bridge Cameras
   This type of cameras includes higher-end digital cameras which have physical resemblance with DSLRs. They are loaded with advanced features as DSLRs but have the compact casing like CDCs, including live preview and small sensor sizes. The modern features include Super Zoom Lenses lacking the reflex and mirror system. These cameras are capable of excellent image quality (with adequate lighting conditions). Many of such cameras can store image in RAW format and do also have option foe JPEG compression.
4. Digital Single Lens Reflex Cameras
   Digital single lens reflex cameras are the digital versions for single-lens reflex cameras (film). These cameras have a mirror and reflex system.
5. Line scan Camera Systems
   These types of camera device have a line-scan image sensor chip and a focusing mechanism. These cameras are conveniently for capturing an image of a constant flow of the movement on industrial scale. These cameras use a single assortment of pixel sensors. Line-scan cameras are capable of capturing data at fast rate with high image resolutions.
   The data from these cameras has frequency which is processed by a computer, which includes the collection of the single-dimensional line data and its conversion to two-dimensional image.
6. Digital Rangefinder
   A range finder camera be it file or digital is fitted with a rangefinder, rangefinder is a device which helps the user to measure the distance and capture the pictures with sharp focus. The first time this range finding technology was applied to digital cameras in 2004 when the Epson R-D1 was introduced. The camera of this sort are capable of capturing two snaps at the same time for a single object, one which is unfocused while other being focused.
   Some digital cameras are mistaken as rangefinder while actually they do not belong to this category and they use electro acoustic and other electronic technologies to measure distance.
