Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
CCD sensors are complex electronic components that consist of multiple arrays of light sensitive semiconductor elements. Each element represents a photo detector, a pixel that converts incoming photons into electrons.
As most people see the world in colour and watch colour television,
there is often an expectation that any image shown on a screen should
be in full colour, and monochrome images seem somehow inferior.
Unlike the monochrome line scan technology, the following specifically covers colour line scan systems. For colour segmentation into the three basic colours red, green and blue (and sometimes a fourth, IR) either single chip cameras with 2/3 (or 4) lines or a prism camera is used.
In the first part to our colour line scan series, we explained how the dual line sensor works.
In this, second, part we'll be covering the prism technology. The following infographic gives you a quick overview of the four different technologies and right below that there's a link to a short video that explains how the prism technology works.
In slow scientific applications such as astronomy, achieving excellent
dynamic range is crucial, as details in the dark areas of an image could
be just as important as those in the brighter sections and minimum
differences in the grey values should be visible. These cameras often
deliver true 14 or 16 bits of dynamic range.
Traditional vision applications are limited to the recording and capture
of images in the visible and near infrared (NIR) spectrum. This limitation
is caused by silicon, the material used in the majority of sensors.
Camera manufacturers include a wide range of functions in their
products to meet the increasing demands of the industrial market.
Some of the key camera characteristics and common features are
discussed in this section.
