Most of us use a digital camera to capture the moments in our life. How does the CMOS sensor of a camera capture an image?

The CMOS (Complementary Metal Oxide Semiconductor) sensor is made up of millions of photosensitive pixels and they convert the incoming light into a voltage value through the use of capacitors and amplifiers. A primary colour filter is arranged over the image sensor so that each individual pixel corresponds with one of the colours red, green or blue and the sensor generates an electric signal representing the brightness of each colour. The image data is then converted to digital signals.
