Introduction to the principle of ccd camera and cmos camera

  Industrial cameras can be divided into ccd cameras and cmos cameras according to the chip. Of course there are other types of chips. But in the current mainstream market, ccd cameras and cmos cameras still account for the majority. However, both the ccd camera and the CMOS camera are hidden inside the camera. It is generally troublesome to distinguish between the two cameras. Below, Shenzhen TEO Co., Ltd. will take you to understand the principle of ccd camera and CMOS camera.

  Ccd camera

  The CCD camera is an abbreviation of a charge-coupled device. After the photosensitive image spot receives illumination, the photosensitive element generates a corresponding current, and the current magnitude corresponds to the light intensity, so the electrical signal directly output by the photosensitive element is simulated. In the CCD sensor, each photosensitive element does not further process this, but instead outputs it directly to the vertical register and to the horizontal register to form a uniform output. Since the electrical signal generated by the photosensitive element is too weak and a large amount of voltage loss is generated in the process, the analog-to-digital conversion cannot be directly performed, and therefore the output data must be uniformly amplified.

  Cmos camera

  The CMOS sensor uses a general semiconductor circuit, which is a technology for powering integrated circuits. Each photosensitive element in the cmos sensor directly integrates the amplifier and analog-to-digital conversion logic. After the photodiode receives illumination and generates an analog electrical signal, the electrical signal is first amplified by the amplifier in the photosensitive element and then directly converted into a corresponding number. signal.

  The above is the introduction of the principle of cdd camera and CMOS camera from TEO industrial camera manufacturers. In fact, CDD cameras and CMOS cameras have their own advantages and disadvantages. CCD provides good image quality, noise immunity and flexibility in camera design. CMOS is an image sensor that can be produced by using contemporary large-scale semiconductor integrated circuit production processes, and has the characteristics of high yield, high integration, low power consumption, and low price. The products of these two chips have different styles in TEO. If you are interested, please consult the TEO website.
