Linea HS 32k CMOS TDI Cameras

The Linea HS 32k TDI Camera



Camera Processing Chain

The diagram below details the sequence of user-adjustable, arithmetic operations performed on the

cameras sensor data. These adjustments are using camera features outlined in the ‘Review of
Camera Performance and Features’ section.

Figure 3: Digital data processing chain

Supported Industry Standards

GenICam™

The camera is GenICam compliant and implements a superset of the GenICam Standard Features
Naming Convention specification V1.5.

This description takes the form of an XML device description file using the syntax defined by the
GenApi module of the GenICam specification. The camera uses the GenICam Generic Control

Protocol (GenCP V1.0) to communicate over the Camera Link HS command lane.
