Twentieth century is an age that is driven by technological progression. One such progress that amazed the world was the creation of camera- a device that could capture the aura of the original and multiply it in umpteen numbers in the form of duplicates with almost similar resemblances. However, with the progress of modern world, technology kept on renewing itself and the year 1988 that saw the arrival of digital camera where images was saved in computerized form. The first true digital camera was the Fuji DS-1P that came with 16MB memory card and a battery. On commercial basis, the first ever digital camera was the Dycam model 1 that could be connected to PC for easy download, maintenance and synchronization.



In comparison to film camera, digital camera has seen unprecedented growth over the past decade or so in comparison to film camera that has a century of history. In terms of viability, digital cameras have become hugely popular among masses as they are easy to use and offer state of the art technology making it the best camera in comparison to film camera. Also, if one takes a general view of digital camera, one will not find any difference in the functioning of the digital camera in comparison to the film camera as both the cameras operate with the press of the button where image is captured through the lens. However, in the case of digital camera, the image is captured with the use of sensor that transforms light into signals.

The brighter image is read as pixels. However, it is misconception to rate the digital camera design according to its pixel rate. In a good digital camera, there are many things that lead to the performance of a digital camera such as the quality of its lens, size of sensor and its pixel rate. The most common digital camera design includes Bayer filter mosaic along with anti-aliasing filter. In order to create RGB color data, demosaicing algorithm is used. Filmware of digital camera includes Adobe Camera Raw that interprets data in order to brilliant images. Some of the other important features in the digital camera design include changing parameters such as modifiable aperture, exposure, focusing, white balance and light metering. The image of digital camera design is stored in the Micro drives and flash memory.

However, the future of digital cameras bright as it will be facing technological refinements rather than inventions as in the case of film cameras that kept on reinventing itself. The digital cameras have revolutionized the image reproduction and it has emerged as the most commonplace medium of capturing the image and transporting it at the speed of light via Bluetooth and the Internet. Presently, digital camera design is used in mobile phones and web cams, professional video cameras, movie cameras and Hubble Space Telescope. Given the advantage of high quality image capture and zoom facility, digital camera design has the huge demand in its market. Indeed, the digital camera design is a revolutionary creation.
