Using Multiple ROIs with LUCID Cameras

Introduction

This document will explain how to use the multiple region of interest (ROI) feature with LUCID cameras.

Requirements

Arena SDK

• Windows: Arena SDK v1.0.31.8 or higher
• Linux x64: Arena SDK v0.1.59 or higher
• Linux ARM64: Arena SDK v0.1.43 or higher

Camera and firmware

• Phoenix: Firmware v1.64 or higher. Not available in dual extended-head models.
• Triton: Firmware v1.75 or higher; available in area scan models not including TDR054S/TRI054S.
• Triton2: Available for all area scan models for all firmware excluding EVS cameras*.
  *EVS cameras have a different multi-ROI method.
• Atlas/Atlas IP67/Atlas10: Available for all models with recent firmware.

Setup Instructions

The following instructions explain how to use multiple ROIs with LUCID cameras. These instructions assume a ROI height of 256 pixels will be used.

1. Stop acquisition if already streaming
2. (optional) Set Acquisition Control -> ISP Clock Speed = Fast
   On supported cameras, this control enables the camera’s ISP to run at a faster rate, which can enable faster framerates.
3. Set Image Format Control -> Multi ROI Rows Enable = True
   
   

These settings will select the following ROIs in the image:

The framerate of the camera will depend on the placement of the ROI rows.
