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 size as required. For preset sizes, click on the "Size" drop down menu and select. Enter values in the "Left", "Top", "Width" and "Height" boxes for custom sizes and location, or click on red box and drag.
Click on "Pixel Addressing" and choose the type of addressing desired. Choose between decimation, resampling, binning or averaging. The addressing factor can then be selected and is camera dependant.
Click "Center" to reposition the ROI in the center of the imager area
To select the appropriate "Pixel format", click on "Pixel Format" drop down menu and select desired setting. Pixel Formats are camera dependant, the most common being 8-bit monochrome for black and white cameras and Bayer 8 for color cameras. Click here to see the entire list of formats possible.
To rotate the image, click on desired setting in "Rotate" section. Most cameras do not support rotate in the camera. The host therefore performs the operation at the expense of greater CPU utilization.
To flip the image, click on desired setting in "Image Flip" section. Most cameras do not support flip in the 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").
