Area of Interest (AOI)
Using this function, you can set the size and position of an area of interest (AOI) within an image. In this case, only data included in this AOI will be read out and transferred to the computer. The smaller partial image enables the camera to use a higher frame rate.
For information on the AOI position grid and the frame rates that your camera model can achieve with AOI, see the model specifications in the Camera and Sensor Data chapter.

The Multi AOI function allows defining more than one AOI in an image and transferring these AOIs all at the same time. Not all uEye models support this feature.
In the Multi AOI mode provided by the UI-124x/UI-524x models, you can define two or four AOIs in one image and transfer them simultaneously. The AOIs are positioned side by side or one below the other, and share the same X or Y axis (see illustration).
