Most cameras have CMOS or CCD sensors.
CMOS (complementary metal oxide semiconductor) is an image sensor used for still and video cameras. It is typically compared with the other type of image sensor called the CCD (charge coupled device). Each has strengths and weaknesses that photographers and videographers can utilize according to their more specific needs.
Sensor Chip
When a camera uses a CMOS-based image sensor chip, it enables the integration of all required camera circuits within the same chip. This makes the CMOS suitable for small and portable cameras such as those in PDAs and mobile phones. Although initially used for less expensive devices, the CMOS sensor has been further developed in terms of power, efficiency and functionality. Many professional cameras already incorporate CMOS sensor chips for their technical needs.
Voltage
Compared to the CCD, the CMOS operates at lower voltages, thus reducing power consumption for portable applications. The CMOS chip allows any analog or digital processing functions to be readily integrated into the chip in order to reduce the device's system package size and overall cost.
Monochrome or Color Configurations
CMOS cameras typically employ color separation devices, instead of having integral filters on the camera's sensors. Each camera might be available in either monochrome or color configurations. A monochrome CMOS camera captures images in black and white or grayscale. A color CMOS camera captures a range of colors generated through varying combinations of discrete colors.
