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.

Nikon D700 — a 12.1-megapixel full-frame DSLR Canon PowerShot A95. Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film.
In addition to the objective, the viewfinder consists of a 45-degree mirror (the reason for the word reflex in the name), a matte focusing screen at the top of the camera, and a pop-up hood surrounding it. The two objectives are connected, so that the focus shown on the focusing screen will be exactly the same as on the film.
There are three exposure parameters – aperture, time (shutter speed), and sensitivity , and in different modes, these are each set automatically or manually; this gives 2 3 = 8 possible modes. For a given exposure, this is an underdetermined system , as there are three inputs but only one output.
