CMOS sensor's sensitivity is normally in the range of 6 to 15 lux. CMOS sensor has 10 times more fix pattern noise than CCD sensor. Fixed pattern noise is the kind of noise patterned. As CMOS sensor will become useless under 10 lux. All camera for serious CCD sensor. CMOS sensor is normally using one toy or very low-end home security. There 2 exceptions. CMOS sensor can be made very big and have the same sensitivity as the CCD sensor. CMOS sensor is very fast, it is 10-100 times faster than CCD sensor, so it is very well such as high ens DSC camera ( Cannon D-30) or fast frame camera. CMOS sensor can have all the logic and control circuit builds on the same silicon wafer dice so as to make the camera simple and easy to handle. Hence CMOS camera can be very that stay on screen as if there is an application are using for special application small in size CMOS camera though consume same or more power then CCD sensor but CMOS sensor useless peripheral circuit such as CDS, TG, and DSP circuit, so the total power consumption is 1/2 to 1/4 less than a CCD camera on the same size. There is only one exception that Digital Camera deals Mintron C series camera is using only 12V/65 mA power which is almost same as CMOS camera but having much better image hence consume very small power (54C0,54C1,54C2,54C154C5,54C6). All other CCD camera making by other company is consuming 12V/150-300mA, hence is 2 to 4 times more than CMOS camera that is on 5-12v and 35-70 mA quality.

C series camera using 0.35um 3.3v DSP Ironically, although CCD stands for "Charge Couple Device" and CMOS stands for "Complementary Metal Oxide Silicon but actually neither CCD nor CMOS has anything to do with image sensing. The actuarial sensor is a device called "Photo Diode" Both CCD sensor and CMOS sensor (as so-called), are using some kind of sensor called Photodiode. The photodiode is a P N junction diode of the light that is bombing the junction into a proportional amount of electron. The amount of electron is them calculated and read as a voltage of the signal. The more the light that entering the photodiode the more the electron generated and the higher the voltage output from the sensor. Digital Camera deals CCD stands for "Charge Couple Device", CCD actually is only the technology to store the electron charge and the method to move these charge out of photosensor in and organized way. CMOS stands for "Complementary Metal Oxide Silicon". CMOS actually is only a technology to make transistor on a silicon wafer, and have no further meaning.
