en.wikipedia.org/wiki/Digital_single-lens_reflex_camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the 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. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the optical viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens.
DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILCs) beginning in the 2010s.
History

In 1969, Willard S. Boyle and George E. Smith invented charge coupled semiconductor devices, which can be used as analog storage registers and image sensors.[1] A CCD (Charge-Coupled Device) imager provides a low noise analog image signal, which is digitized when used in a digital camera. For their contribution to digital photography, Boyle and Smith were awarded the Nobel Prize for Physics in 2009.[2]
In 1973, Fairchild developed a 100 x 100 pixel interline CCD image sensor.[3] This CCD was used in the first commercial CCD camera, the Fairchild MV-100, which was introduced in late 1973. In 1974, Kodak scientists Peter Dillon and Albert Brault used this Fairchild CCD 202 image sensor to create the first color CCD image sensor, by fabricating a red, green, and blue color filter array which was registered and bonded to the CCD.[4] In 1975 Kodak engineer Steven Sasson built the first portable, battery operated digital still camera, which used a zoom lens from a Kodak Super 8mm movie camera and a monochrome Fairchild 100×100 pixel CCD.[5]
