Classification of Industrial Cameras

CMOS

• Integrated on semiconductor materials of metal oxides.

• Low manufacturing cost and power consumption.

• Color restoration ability is weak.

• CMOS chips have roller shutter exposure and global exposure. Roller shutter exposure is suitable for photographing still objects.

• Shooting moving objects will have shadows and the image will be deformed.

• Global exposure.

• You can shoot still or moving objects.

CCD

• Integrated on semiconductor single crystal materials.

• High manufacturing cost and power consumption.

• Relatively strong color restoration, good image sharpness and clarity.

• The exposure mode of CCD chip is generally frame exposure or global exposure.

• It can shoot still or moving objects.

Linear array camera

• Linear chip.

• There must be relative motion between the camera and the object to image;

• Relatively high price.

• High line frequency and lateral resolution;

• Due to the large amount of data transmitted, the data transmission interface is generally GigE interface, Cameralink interface and coaxpress interface.

Area array camera

• Area array chip, and the common camera interfaces are C ,  CS ,  F；

• Object can be imaged when it is still or in motion;

• Prices vary according to performance;

• Can obtain two-dimensional image information in real time and measure the image intuitively;

• Data transmission interfaces include GigE, IEEE1394, USB, camera link and other interfaces.

Colorful camera

Image is colorful.

Monochrome camera

Image is black and white.

Analog camera

• Low resolution, common 400000 pixels, slow acquisition speed, frame rate of 30 frames per second, low price;

• Divided into progressive scanning and interlaced scanning, which are generally interlaced scanning, and the image transmission is vulnerable to noise interference, resulting in the decline of image quality;

• analog signal, and the image acquisition card is used outside the camera   Mold/   Digital signal conversion;

• Mostly used in real-time monitoring and other security industries, and the market utilization rate is gradually decreasing

Digital camera

• Resolution ranges from 300000 to 120 million, with fast acquisition speed and different prices;

• Roller shutter exposure and global exposure, good image quality;

• Digital signal, which is completed in the camera/  Digital signal conversion;

• Gradually replace analog cameras.

By signal output speed

can be divided into ordinary speed camera and high-speed camera;

By response spectrum

can be divided into visible (ordinary) camera, infrared camera, ultraviolet camera, etc.
