The Region of Interest tab controls the size of the image being captured and its location with respect to the entire image array.



ROI Size and Location



The Region of Interest (ROI) is the area of the sensor being viewed at any given time. The region of interest appears as a red frame superimposed in the "Region of Interest - Size and Location" window. Full view of the sensor is shown in white and is camera dependant.

  • Select the ROI Size as required.  For preset sizes, click on the "Size" drop down menu and select.  Otherwise, you can enter values in the "Left", "Top", "Width" and "Height" boxes for custom sizes and locations, or click on the red box and drag.


  • To enable Pixel Addressing, first click on the Value (Width by Height) drop down menu, to select the desired pixel addressing value. Then click on "Pixel Addressing" and choose the type of addressing desired. Choose between decimation, binning, or (for some PL-B cameras) resampling or averaging. 


  • Click "Center" to reposition the ROI in the center of the imager area


  • To select the appropriate Pixel Format, click on the "Pixel Format" drop down menu.  Pixel Formats are camera dependant; The most common being 8-bit monochrome for black and white cameras, and Bayer 8 for color cameras.


Rotation


To rotate the image, click to select the desired degree of rotation.  Most cameras do not support rotate "on camera".  The host therefore performs the operation at the expense of greater CPU utilization.



Image Flip


To flip the image, click the "On" button to enable horizontal and/or vertical flip.  Most cameras do not support flip "on camera".  The host therefore performs the operation at the expense of greater CPU utilization.



Note: If the ROI is changed while the preview window is open, the preview window may need to be reset manually (CTRL + R, or click on "View", left click on "Reset Preview Window").
