6. Functions and Operations

In the following the format shown in “7.5. CV-M2 command list” are used for function commands and parameters.

6.1. Basic functions

The M2 camera is a progressive scan camera with 10 or 8 bit video output in single or dual channel Camera Link. On a BNC connector a standard composite video output CCIR or EIA for monitor use is found. The image covers the full format, but the resolution is much lower than the digital video output.

An iris video signal can be used for lens iris control if the camera is in continuous mode or Reset Continuous Trigger mode.

A knee function (and gamma for single channel) makes it possible to cover high contrast scenes. The CV-M2 camera has 1/2, 1/4 or 1/8 partial scanning. Programmable partial scan, where the start line and the number of lines can be selected in 1line increments is also available.

There are 5 trigger modes. Normal continuous, reset continuous trigger, edge pre-select, pulse width control, edge pre-select burst trigger and PIV trigger. (PIV, Particle Image Velocimety). The Sensor Gate Control can be used in normal continuous mode together with strobe flash. The accumulation can be LVAL synchronous or LVAL a-synchronous.

In the following some of the functions are shown in details.

6.1.1. Dual video output

The video read out through Camera Link can be via a single or via double channels. (OS=0 for single channel, OS=1 for dual channel.) If dual video outputs are used, the frame grabber PC should reconstruct the image frame from the 2 half images.

6.1.2. Burst trigger

With the burst trigger function TR=4, five previous set edge pre-selected programmable exposures can be done with a single trigger pulse. The five shutter times can be set with BSH1 through BSH5. (1H through 1216H.)
