Applications
The S2 image sensor has many
special features. The unique
combination of benefits it provide
make it the ideal solution for many
visual sensing tasks in a wide range
of application areas.
The sensor is particularly
suitable for applications
where image consistency

Technology
The S2 sensor uses patented time-domain logarithmic encoding to yield
a very wide intra-scene dynamic range and to optimally expose every
image. On chip real-time edge extraction processing and image memory
enable low cost, low power processors to be used with the S2 sensor.
