What's the difference between CCD and CMOS image sensors?
An image sensor is a device that was used to convert optical images into electronic signals. Nowadays, CCD and CMOS are the two most commonly used technologies to do the conversion.
The major advantage of CCD sensor is that it outperforms CMOS sensors in its light sensitivity. Moreover, its early maturity of technology also makes it the dominant image sensor utilized in the video camera industry.
A CMOS sensor, also known as Active Pixel Sensor (APS), consumes less power than a CCD one. Though, a late comer regarding to its development history, its prevalent applications in the IC industry and hence lower manufacturing cost is pushing it fast forward to become the next generation image sensor in the coming years. Yet, currently, most CCD video cameras still outperform their CMOS counterparts in the performance of the color image presentation, especially in low light conditions.
