Digital and Interlaced?

It was ready in time for VISION 2006, arguably the most significant trade fair in the world for the image-processing industry. Allied Vision Technologies presented the new entry-level Guppy camera family, showing once again that the switch from analog to digital technology is also becoming more and more interesting from a business point of view.

And, the Guppy family keeps growing. The next resolutions have already entered the development planning stage. With the publication date of this issue of Advanced Imaging, a Guppy camera with CMOS sensor (wide VGA) is already scheduled to go into series production.

However, development will not stop here, as another twelve Guppy family members will soon extend this series. The models integrate 100 percent into the family. They have the same case measurements and the same functions, but they are marked by a difference that is probably unique in the digital world at the moment: they are digital cameras with interlaced sensors.

Today, interlaced sensors can be found throughout the analog video and television world; they are probably the most widely used of all CCD sensors. So it goes without saying that these sensors are also very well known in industrial image processing and are used in the majority of applications with analog cameras.

Interlaced sensors offer many interesting benefits: they are extremely sensitive and achieve picture results that cannot be achieved in a shot carried out using a progressive scan sensor.
