1.2. Using This Manual
This manual attempts to provide the user with a detailed specification of the Grasshopper camera
system. The reader should be aware that the camera system is a complex and dynamic system –
if any errors or omissions are found during experimentation, please contact us.
This document is subject to change without notice.
Many of the operational descriptions included in this manual are intended as general overviews,
and may not present the detailed information required for developing specific applications. For
