Hamburg, Germany — With the introduction of a high-resolution CCD sensor for security cameras, Sharp has significantly raised the bar for high-performance imaging devices. The RJ33J3AA0DT image sensor provides a resolution of 1.3 megapixels and is at the top of the range in terms of image sharpness for CCD sensors for security cameras. This CCD sensor is particularly suitable for cameras at airports, railway stations and other busy places where it is often neceassry to digitally zoom in on individual sections of a panoramic shot in order to show fine details such as faces in sharp definition. Conventional CCD sensors with a resolution of only 0.27 or 0.32 megapixels quickly reach their limits in terms of digital enlargement of image details.
Amongst other things, the high image reproduction quality of the 1.3 megapixels CCD sensor is based on its high sensitivity. At 400 mV, this lies at the upper end of the scale for CCD security sensors of the megapixel class. Furthermore, the low smear factor of only -105 dB provides clear images, particularly under difficult lighting conditions. It largely eliminates smear effects caused by intensive light, for example from spotlights at night. The integrated blooming suppression also plays a crucial role here.
Thanks to progressive scan technology, the RJ33J3AA0DT is also able to provide sharp images of rapidly moving objects. At full resolution of 1.3 million pixels, the sensor can capture 22 frames per second. In the 4 pixel mixing VGA mode, the recording speed is even as high as 30 frames per second. A further advantage of the progressive scan recording technology is that the images can either be fed directly into computer-supported TCP/IP-based networks or processed by analogue systems.
