For many global security systems, the optical format was decided by the initial choice of the image sensor, for instance a 1/3” VGA sensor or 2/3” HD CCD image sensors with pixel sizes of 6 or 7 µm. These legacy systems are now due for upgrades to take advantage of the sensitivity, lower read noise…
We have talked about the move from CCD to CMOS in global security systems with the increase in low light performance (better NIR sensitivity and lower noise) of the latest CMOS global shutter image sensors.
Ruggedized, high-resolution digital HD and beyond CMOS cameras to upgrade from CCD to expand identification capabilities in low light
At the 2016 SPIE DCS 2016, Adimec demonstrated rugged CCD cameras and latest generation (Sony IMX250) CMOS based rugged cameras with color in low light.
It is a challenge to obtain an accurate color representation on your video screen when imaging a scene from sunrise to sunset, e.g. imaging under changing lighting conditions. White balance is a function inside cameras to overcome this challenge. When a colorful scene is recorded without adjusting the white balance of the camera, the color…
SAPPHIRE quality plus Quad CXP configuration offers most reliable, low power implementation for ultra high-resolution, high-speed camera
At the 2016 Vision Show in Boston this week, Adimec demonstrated the new S-25A80/CXP as well as other metrology camera innovations.
With machine vision applications, some of the most important specifications beyond resolution and frame speed to determine whether the camera meet the measurement requirements, are full well capacity, Signal to Noise Ratio (SNR), and dynamic range (DR) specifications. Interpreting these values from specification sheets can be challenging though. The full well capacity and SNR definitions…
There is a move from CCD to CMOS daylight cameras in global security systems with the increase in low light performance (better NIR sensitivity and lower noise) of the latest CMOS global shutter image sensors. Here are several articles that offer some tips on how to take advantage of the latest technology:
Flat Field Correction in Machine Vision Cameras We recently published a series of articles about using Flat Field Correction in high-resolution Machine Vision cameras. In the first article we discuss what kinds of artifacts may be created by illumination optics and, we provide three suggestions of how to remove the influence of the light source…
