is a device that converts a visual image to an electric signal.
It is used mostly used in digital cameras and other imaging
devices. It is a set of charge-coupled devices (CCD) or CMOS
sensors such as active-pixel sensors. There are several main
types of color image sensors, differing by the means of the
color separation mechanism: CCD Vs CMOS Today, most digital
still cameras use either a CCD images sensor or a CMOS sensor.
Both types of sensor accomplish the same task of capturing light
and converting it into electrical signals. A CCD is an analog
device. When light strikes the chip it is held as a small
electrical charge in each photo sensor. The charges are
converted to voltage one pixel at a time as t
