Sensors and Functionality
These ultra compact, lightweight CCD cameras feature USB connections, making them extremely versatile for a wide range of applications including industrial automation, quality control, medical imaging, microscopy, and security technology. The DCU223 models are equipped with a high-quality SONY 1/3" CCD sensor with XGA resolution (1024 x 768) and provide a full frame repetition rate of 30 fps. The DCU224 models have a 1/2" CCD sensor with SXGA resolution (1280 x 1024) and provide a full frame repetition rate of 15 fps.
For all models, higher frame rates can be achieved by using the Area of Interest (AOI) or Binning functions; the former increases the frame rate by only reading a selected area of the sensor, whereas the latter increases the frame rate by combining pixel readings before transferring them to the PC, but in this case, image resolution is sacrificed. The computer can communicate digitally with the camera through the USB 2.0 interface, thus enabling the user to transmit images and control camera settings seamlessly.
