An imaging method includes assigning pixels within the extent of a focal plane array active area to a first readout range and a second readout range. Image data is read out from the pixels assigned to the first readout range and the second readout range. Pixels located within the extend of the focal plane array active area and not assigned to the first readout range or the second readout range are left unread. Imaging systems and hyperspectral imaging arrangements are also described.
