Functions and Operations
6.1.
Basic functions
The CM-200
MCL / CB-200
MCL cameras are progressive scan camera with 2 Mega pixels
monochrome and Bayer mosaic color CCDs . The interface to the host PC is via digital Mini Camera
Link (Mini-CL). Both models output video as 8 bits or 10 bits. The CB-200
MCL outputs raw Bayer
video requiring host based color interpolation.
An analogue iris video signal can be used for controlling the iris of an auto iris lens when operating
in continuous mode.
The camera has 2/3, 1/2, 1/4 or 1/8 partial scanning and vertical binning ( CM-200MCL only )for
faster frame rates .
There are 2 trigger modes in addition to continuous operation . The Edge Pre-Select and Pulse
Width Control are available with a unique automatic LVAL sync or a-sync selection function.
Below the functions are described in details.
