Talking about the main types of CCD industrial cameras

Industrial cameras are a key component in machine vision systems, and their most essential function is to transform optical signals into ordered electrical signals. Choosing the right camera is also an important part of the design of the machine vision system. The camera not only directly determines the image resolution and image quality, but also directly relates to the operating mode of the whole system.
The CCD was invented by Bell Labs in the late 1960s. Beginning as a new type of PC memory circuit, CCDs soon have many other potential applications, including signal and image (silicon photosensitivity) processing.

CCD is a series of different functions on a thin silicon wafer. Several functional ICs are distributed on each silicon wafer. The selected IC is cut from the silicon wafer and packaged in the carrier. On the system. To sum up, CCD industrial cameras mainly have the following types:
1. Area CCD industrial camera:
Allows the photographer to shoot moving objects at one exposure at any shutter speed.
2, line array CCD industrial camera:
Scan the image with a row of pixels and make three exposures—corresponding to the red, green, and blue filters, respectively. As the name suggests, the linear sensor captures a one-dimensional image. Initially used in the advertising industry to capture still images, linear arrays, when dealing with high-resolution images, subject to non-moving continuous illumination of objects.
3, three-wire sensor CCD industrial camera:
In the three-line sensor, three rows of parallel pixels cover the RGB filter respectively. When capturing a color picture, the complete color picture is composed of multiple rows of pixels. Three-line CCD sensors are mostly used in high-end digital cameras to produce high resolution and spectral color gradation.
4. Interlaced transmission CCD industrial camera:
This sensor utilizes a separate array to capture images and power conversion, allowing the current image to be read while the next image is being taken. Interlaced transmission CCDs are commonly used in low-end digital cameras, video cameras, and broadcast cameras that shoot movies.
5, full-format CCD industrial camera:
This CCD has more power handling capability, better dynamic range, low noise and transmission optical resolution, and the full-format CCD allows instant shooting of full-color images. The full-size CCD consists of a parallel floating-point register, a serial floating-point register, and a signal output amplifier. Full-format CCD exposure is controlled by a mechanical shutter or gate to save the image, and parallel registers are used to meter and read the metering value. The images are projected onto a parallel array of projection screens. This element receives the image information and divides it into discrete elements that are quantized by the number. These streams of information flow from the parallel registers to the serial registers. This process is repeated until all the information has been transferred. The system then performs an accurate image reorganization.
