Even though SLR cameras adopted digital image sensors as far back as the 1980s, other key components have remained defiantly mechanical. Mirrorless cameras removed the mirror and optical viewfinder ...

The purpose of a shutter is to control the amount of light reaching the image sensor. Back in the days of film, mechanical shutters were the only option and there were only two types: focal plane and ...

The Part 1 of this series about digital camera design has shown how to do the basic calculations that interrelate pixel size, focal length, focal ratio, and spot size, and demonstrated how these ...

Some image sensors must either use a mechanical shutter or a pulsed light source to capture an image. For example, full-frame CCD image sensors, that are used for scientific applications such as ...
