9.4 Region of Interest (ROI) and Binning
The ROI and binning controls are found in the
“AOI”
tab (Area of Interest) on the XCAP GUI.
ROI:
A region of interest within the main active region of 2048 × 2048 may be defined (or
1024 x 1024 if using the 47-10 model). The ROI is setup using a bank of registers to control
the X offset, the ROI width, the Y offset and the ROI height. These parameters are shown
pictorially in Figure 9.
The user must ensure that X ROI width is ≤ 2048 and similarly
the Y ROI height is ≤ 2048 (or 1024 if using the Eagle XV 47-10 model). Also, ROI
width and ROI height must be > 0.
Binning:
In addition to standard 1×1 output, various levels of pixel binning may be
programmed up to 64*64. Pixel binning is performed on the CCD and asymmetric binning
combinations may be used e.g. (1 × 2); (2 × 1); (1 × 3); (3 × 1); (4 × 7) etc. XCAP gives the
user a lot of different binning options to choose from. If there are binning formats that the user
wishes to use that are not an option in XCAP, please contact Raptor for support.
The ROI and Binning may be active simultaneously. The ROI is determined on a single pixel
basis after which binning may be applied. The ROI and binning controls in XCAP are shown
in Figure 19.
