1 leanXcam
1.1 Introduction
leanXcam is an intelligent colour camera with a rich set of features that provides an impressive
performance, in spite of its low production cost. The smart combination of a well-established sensor
chip, a fast digital signal processor, a tailored Linux-based operation system and the image processing
framework from SCS-Vision makes the leanXcam an incomparable achievement in the field of Vision.
Communication is ensured by Ethernet connection and digital I/Os.
1.2 Purpose of this document
This document gives an overview of the leanXcam HW and provides information about the used
devices, interfaces and some examples. This document should be used by readers who are interested
in the physical blocks contained in the leanXcam or by readers who want to use more debug features
like RS232 and JTAG, when designing with the leanXcam.
