 The Image Sensor is an electronic device which requires power to operate. The sensor is made up of thousands of pixel, each of which is like a silver grain in a conventional film. At this stage no sensor, even those covering the full area like a 35mm film frame, can reproduce the same amount of information as that contained in a frame of conventional film. But some are getting very close and for most general purpose photography the digital sensor produces remarkable results.
Mechanically the Digital SLR camera is very much like its film relative - that is, it has a shutter, mirror mechanism and a prism viewfinder. However, the film transport and film has been replaced with an Image Sensor and associated electronics to capture and store images.
In the digital SLR camera the Image Sensor is a stationary device, and because there is no film moving across the focal plane each time a frame is exposed, dust and debris is more likely to accumulate and cause spots on the images.
Keeping the digital camera body, mirror chamber, and lenses clean is therefore more important than with a conventional film camera and the Image sensor should to be inspected and cleaned regularly if you want to avoid annoying spots on your photos.
