Introduction

The Advanced Camera Operation Manual includes:

•Imager Control Language (ICL)— Rules of syntax, ASCI II command set, and example scripts

•Advanced CCD Theory — Background theory for advanced ICL users

Most Roper Scientific cameras use an application programming interface called PVCAM® (Programmable Virtual Camera Access Method). PVCAM is a custom, ANSI C library of camera control and data acquisition functions. Full- function imaging packages access PVCAM. These full-function packages offer the camera control adequate for most users.

ICL is a PVCAM option library that allows users to write low-level, ASCI II command scripts for specialized applications. The scripts, which can be written in any text editor, are then loaded through an ICL-compatible, full–function imaging package, into the ICL option library, then through PVCAM to the camera interface.
