Looking for Area Scan or 3D Pixel Formats? Visit our Area Scan Pixel Format and our 3D Pixel Format pages for more information.

Introduction

Understanding pixel formats allow you to understand how images are put together. More specifically,  understanding these pixel formats will help you if you need to extract specific information from the pixels in the image that you receive from the camera.

Linescan ROI

Linescan ROI

The Region of Interest feature allows you to specify a section of the line sensor used for image acquisition.  ROI allows a custom width and height for image size and a custom X offset for image position.

The location and the size of the Region of Interest is defined by setting an offset X and a width in pixels. For example, setting Offset X as 10 and width as 2030 would result in a Region of Interest as shown below.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ...
