The Difference Between Car Camera CCD And CMOS Chip
Jun 08, 2018

The installation of on-board cameras can reduce the potential for accidents and facilitate the driver to clearly understand the inside and outside of the vehicle. A large part of the performance of the car camera depends on the electronic components inside. Different chips have different functions and characteristics. What is the difference between a car camera CCD chip and a CMOS chip?

The advantages of CCD are:

1. Mature technology

2. High imaging quality

3 high sensitivity, low noise, large dynamic range

4. Fast response, self-scanning function, small image distortion, no afterimage

5. Application of VLSI process technology, high pixel integration, precise dimensions

Disadvantages: the degree of color reproduction is conservative, the color is not cmos gorgeous, the purchase price is higher than the cmos

CMOS advantages and disadvantages:

Advantages: Low cost, bright colors, suitable for solving most security markets

Disadvantages:

1, the difference in image color reproduction

2, color cast, night reddish (with 850 filter)

3, to achieve color is not color cast lens and IR need to switch between day and night to compensate for image color cast problem. (IR market quality is uneven, generally used in the security industry, because the use of the vehicle is not the same environment, the high frequency of vibration is likely to cause IR to crash when switching to cause the image is not normal.

By comparing the CCD chip function to meet the needs of the automotive market, stable imaging is convenient for drivers to watch and prevent accidents. The onboard camera with CCD chip can be applied to large vehicles such as buses, passenger cars, large trucks, logistics vehicles, and special vehicles.
