A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This allows cameras that were designed to use film take digital photographs .
A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing.
By comparison, the dimensions of the photosite array in the 10.2 MP Bayer sensor in the Nikon D200 camera are 3872 × 2592, but there is only one photodiode, or one-pixel sensor, at each site. The cameras have equal numbers of photodiodes and produce similar raw data file sizes, but the Bayer filter camera produces a larger native file size via ...
In 1987, this sensor was integrated with a Canon F-1 film SLR body at the Kodak Federal Systems Division to create an early DSLR camera. [9] The digital back monitored the camera body battery current to sync the image sensor exposure to the film body shutter.
A Kodak DCS 420, a 1.2-megapixel digital SLR based on a Nikon F90 body. The Kodak Digital Camera System is a series of digital single-lens reflex cameras and digital camera backs that were released by Kodak in the 1990s and 2000s, and discontinued in 2005. [1] They are all based on existing 35mm film SLRs from Nikon, Canon and Sigma.

The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
A digital scan back or scanning back is a type of digital camera back. Digital imaging devices typically use a matrix of light-sensitive photosensors , such as CCD or CMOS technologies. These sensors can be arranged in different ways, like a Bayer filter , where each row captures RGB components, or using one full-sized layer for each color ...
Exmor R is a back-illuminated version of Sony's CMOS image sensor. [5] Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology. [6] [non-primary source needed] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor.
