Whats the difference between CCD and CMOS sensors in dslr cameras?
The digital camera works by using a light sensor or chip which absorbs light particles converting them into electrical charges. The light sensor is divided up into many small arrays of receptor cells. The more light these arrays of cells exposed the more light is recorded. These cells alone cannot recognize the different colors of the spectrum so during exposure primary colored filters are used in front of the image sensor which are a charged-couple device or CCD The charge generated by the CCD is stored as analogue information until it s digitized from analogue to digital converter or ADC. Every receptor in the array is equivalent to one pixel and it is the pixels that make up an image. Not all digital cameras use CCD chips as image sensors. Some cameras use CMOS chips, or Complementary Metal Oxide Semiconductor. The CMOS based sensors are manufactured using the same process that is used to mass produce DRAM and microprocessors. CMOS sensors are cheaper and easier to manufacture than
