The Giganetix Plus series of cameras offers the Sony IMX174 image sensor, providing high sensitivity, dynamic range, low noise, and crisp images of moving objects. SMARTEK Vision's industrial GigE camera GCP1931 with Sony's first image sensor based on the CMOS technology with global shutter, impressed the visitors at The Vision Show in Boston in April. Moving object inspection, low light and outdoor applications used to be the core domain of CCD sensors. Now, thanks to Sony's advances in sensor technology and SMARTEK Vision's expertise in camera design, these applications and scenes with simultaneously bright and dark areas can now be resolved better and more cost effectively. With a resolution of 2.3MP at a high frame rate of 50fps, high sensitivity due to the Sony Exmor technology and large pixels of 5.86μm, SMARTEK Vision utilises the full bandwidth of Gigabit Ethernet based on the proven GigE Vision standard data interface. The sensor and the camera design allows for a significantly more economic solution compared to the CCD sensor technology at similar or better image characteristics. The basis for this machine vision revolution is Sony's recently developed analog memory that allows for the unification of the best of both CCD and the CMOS technology developments. A clean conversion of light collected at the photodiode and shielded from noise sources results in very high sensitivity. No fixed pattern noise and a low read noise of 7e- in combination with a high dynamic range from 70db and a peak quantum efficiency over 75%, enables distortion-free images without any smear or rolling shutter artefacts. All sensitivity factors lead to lower power consumption due to the ability to work in a wide range of lighting conditions.
