Image Sensors Explained: How CCD and CMOS Sensors works? CCD vs CMOS

Ғылым және технология

In this video, modern-day image sensors like, CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) have been briefly explained. And the comparison between CCD and CMOS sensor is carried out in various aspects.
Both CCD and CMOS sensors consist of an array of tiny photosites (pixels) which converts incoming light into the charge.
The following steps are common in both CCD and CMOS sensors, but the sequence in which it is carried out might differ in two sensors.
1. Conversion of incoming light into the charge
2. Charge Accumulation
3. Charge Transfer
4. Charge to Voltage Conversion
5. Voltage amplification
CCD Sensor:
In case of CCD Sensor, the incoming light is converted into charge, and then charge to voltage conversion is carried out, outside the sensor area.
Most CCD sensor has a single charge to voltage conversion circuit and single amplifier. So, charge from each pixel is transferred to the next row (or next column) and eventually to the shift register.
In shift register, the charge is transferred one by one and then it is converted into the voltage.
CMOS sensor:
In case of CMOS sensor, the charge to voltage conversion and voltage amplification is carried out in the pixel itself. So, each pixel has its own charge to voltage converter circuit and voltage amplifier circuit. Such CMOS sensor pixels (which contains amplifier) are known as the active pixel sensor.
In case of CMOS sensor, the reading of the pixel voltage is carried out in line by line fashion.
Comparision of CCD and CMOS sensors:
1. System integration:
In case of CMOS sensor as the peripheral circuit is also integrated into the sensor chip itself. While in case of CCD sensor, for peripheral components, the different chip is required.
2. Power Consumption:
CMOS requires less power than CCD Sensors.
3. Processing Speed:
CMOS sensor is much faster than CCD sensors.
4. Noise and sensitivity
CCD sensor has less noise than CMOS sensor and also it has better sensitivity. But nowadays using different techniques like microlens on each pixel of CMOS sensor, the sensitivity can be increased.
Time stamps for the different topics are given below:
0:34 Overview of CCD and CMOS Sensors
1:36 How CCD Works?
2:53 How CMOS sensor Works?
4:01 Comparision between CCD and CMOS Sensors
4:11 Comparision in terms of the system integration
4:51 Comparision in terms of Power Consumption
5:37 Comparision in terms of the Processing Speed
6:33 Comparison in terms of the Noise and Sensitivity
7:25 Comparision in terms of the image distortion
This video will be helpful to all in understanding the CCD and CMOS image sensors.

    That's pretty good. I was looking for a video that visually described how light is tiurned into an electrical charge, then voltage before being digitized, for the benefit of people who think that everything electronic is magically digital. In fact, the best CCD video cameras have the ability to control amplifier gain to eliminate analog or digital clipping before the photosite information is digitized. That and the absence of rolling shutter, that cannot be eliminated on CMOS, makes CCD the overwhelming choice when best image quality is needed. This will no doubt spur vehement denial among "cinema" fanbois, but it's a fact. CMOS is less costly to make, and is better for battery-powered things like phones, and other mass market devices. Being cheaper makes it more widespread, but when dynamic range and temporal factors matter, you need CCD.

    Excellent explanation. If CCD is an intrinsically superior technology for capturing still images then it is a shame that the many ways CMOS sensors have been improved to give high ISO capablity (better microlenses, less dnes pigment in the CFA, quieter on-chip circuitry, ... ) have not been applied to CCD, and that features and convenience (and manufacturing cost) have been prioritised by camera makers over image quality.

    CCD sensor is superior quality than CMOS sensor, but CCD sensor needs to much resources such as power and price. I believe the CCD sensor is still improved, but not for regular consumer because it will be too expensive.

Any video explain why CCD needs to have the 1-by-1 shift register unlike the CMOS? why can't CCD have batch process on charges like the CMOS?

    In CCD, suppose charge to voltage conversion as well as amplification is performed parallelly, then imagine the number of the amplifier and the converter circuits required for the CCD sensor. It will be in thousands!! In case of CMOS, it is possible to accommodate millions of amplifier circuit because the fabrication procedure is same as the IC fabrication technique. In CCD fabrication technology it is difficult to accommodate so many amplifiers. So, conversion is performed serially.

    What's causing the charges to be shifted into the read register. No one explains that part... I imagine the read register is connected via a row of capacitors with one side being the pixel array accumulating a negative charge and forcing a positive charge on the other plate of the capacitor and connected to that is a MOSFET row (MOSFET Gates) at the edge of the CCD which would allow the amplification to be simply the Drain to Source Voltage being controlled by the MOSFET's Gate to Source voltage. Then you would "Shift" the charges from the CCD sensor to the read register by exposing the the MOSFET Gate to a positive voltage drawing the charge off the CCD's pixel array and onto the MOSFET's Gate which then controls a large voltage being sent to the DATA inputs of the D Flip Flop of the Read Register. JUST GUESSING

    beside charge to voltage conversion and amplification happening in the pixel as opposed to the serial register, I cannot see how the transfer of the data differs between the CCD and CMOS. It just seems like the charges are being read column-wise for the CCD, and row-wise for the CMOS. And that shouldn't yield any difference...?
