Digital cameras became common as the decline in the selling price. One of the drivers behind the falling prices is the introduction of a CMOS sensor. CMOS sensors are much more expensive to manufacture than CCD sensors.
Both sensor CCD (charge-coupled device) and CMOS (complimentary metal-oxide semiconductor) function at which convert light into electrons. To find out how the sensor works we must know the working principle of solar cells. Think of it as the sensor used in digital cameras like having thousands and even millions of tiny solar cells in the form of a two-dimensional matrix. Each of these will sell a small portion of light transform the captured image into electrons. Both of these sensors do the work with a wide range of existing technologies.
The following step is to read the value of each cell in the image. In a CCD camera, the value is sent to the chip and an analog-to-digital converter convert each pixel's value into a digital value. In a CMOS camera, there are several transistors at each pixel that amplify and move the charge using the cable. CMOS sensor is more flexible because each pixel can be read individually.
CCDs use a special manufacturing process to create the ability to transport charge across the chip without distortion. Within the meaning of the CCD sensor the better the quality the sharpness and light sensitivity. Another case, CMOS chips are made with a more traditional way in the same way to make microprocessors. Because the manufacturing process is different, there are some fundamental differences of CCD and CMOS sensors.
