Digital camera has a built in computer wherein the light is directed into the semiconductor apparatus which then electronically captures the light and the information is passed on in the form of a picture or a photograph. The greatest feature of this computerised camera is the fact that the sensor converts the light into electrical charges. Engineers do not agree to the fact that a CMOS can replace the CCD. The CCD attracts electrons when it comes in contact with photons or other light particles. These diodes respond very well to light which implies that when the light is bright, more electrons would get attracted. The prices of these cameras are getting lower and lower. The cost of CMOS sensors is low and the manufacturing cost is lesser than that of CCD sensors. The working of the CMOS sensors and CCD sensors are similar as both convert the light electrical charge into photosites.
