It was because of the projection that scientists began to investigate how to fix that image and be able to preserve it for a long time. Since the sixteenth century, numerous investigations have been done and thanks to them, today we can enjoy photography as a memory of something that already was.
All cameras, from the first one that was invented, have a sensor. Over the years, this has evolved, from being a sheet of paper very receptive to light, through the film (the roll) also of this type of material, to the digital, a very complex chip with high components sensitivity. However, when we see that our cameras have a CCD or CMOS sensor, we are confused without actually knowing what it means or what the difference is.
Better performance in a simpler structure, without the need for more equipment.
Less sensitive to light, but much lower energy consumption, so cameras are cheaper.
So summarizing these points we will indicate the advantages of one over the other:
CCD sensors create high quality images with little digital noise ; CMOS sensors are more sensitive to it.
cmos sensor socket manufacturer consume less energy; a CCD sensor can consume up to 100 more energy than the CMOS; This makes the battery last longer in a camera with this type of sensor. The time it takes to take a picture and be able to see it is faster on cameras with CMOS.
In reality, neither is better than the other, they are simply sensors that provide different characteristics to each of the digital cameras . Current technology has caused the CMOS sensor (in theory, lower than the CCD) to approach a quality very similar to the CCD so that, for the human eye, the differences are almost imperceptible.
