A digital camera, also called a digicam, [1] is a camera that captures photographs in digital memory. Most cameras produced today are digital, [2] largely replacing those that capture images on photographic film or film stock.
Digital photography spans a wide range of applications with a long history. Much of the technology originated in the space industry, where it pertains to highly customized, embedded systems combined with sophisticated remote telemetry. Any electronic image sensor can be digitized; this was achieved in 1951.
The history of the camera began even before the introduction of photography. Cameras evolved from the camera obscura through many generations of photographic technology – daguerreotypes, calotypes, dry plates, film – to the modern day with digital cameras and camera phones.
Viewfinder eyepiece. A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras.

The following digicams include a -inch CCD sensor, a fixed lens with a maximum aperture of f/ 2.4 or wider, and SD or CompactFlash (CF) memory card slots. However, none of them support SDHC / SDXC memory cards or AA / AAA batteries. Even larger CCD sensors were only included in interchangeable-lens cameras, such as the Canon 1D, Nikon D60, and ...
