For machine vision use, CMOS sensors that feature a global shutter
enable sharp images of fast moving objects as all pixels are exposed
at the same time in the same way as progressive scan CCD sensors.
However not all CMOS sensors use Global shutters, some use a
Spatial resolution refers to the number of active pixels on the sensor.
When designing a system, it is important to calculate the optimum
camera resolution in order to be able to solve the inspection task in a
robust and cost-effective way.
The machine vision industry is constantly investing in technologies to
address difficult to image applications. As a result there are many niche
sensor developments that can be an excellent solution to specific
applications. STEMMER IMAGING is constantly evaluating these
developments to deliver focused solutions.
The human eye can react to wavelengths between approximately 400
to 700 nm. Most vision applications use light in this range, but some
applications require the use of a camera which is sensitive towards
either the infrared or ultraviolet spectra.
En principe, il existe deux types de capteurs utilisés dans les caméras de
traitement d'images, CCD et CMOS. Les capteurs CCD peuvent être classés en 3
architectures différentes: frame transfer, full frame et interline transfer.
En ce qui concerne les capteurs CMOS, il ya beaucoup de différentes
architectures de complexité et de performance variable.
The first version of USB (Universal Serial Bus) was developed in 1995 by
a consortium of NEC, IBM, Intel, Microsoft and others. The purpose was
to provide a simple link between computers and peripheral devices.
