Vertical ROI Example (monochrome)

Attention

Because the readout is dual-sided (top/bottom), the sensor top sequencer must be programmed to

only access rows in the upper half of the array (1860 to 3719) and the bottom sequencer to only

access rows in the lower half of the array (0 to 1859).

Small Window Mode

When reading out small windows, the unused rows are disabled to decrease the global

sampling time and finally increase the frame rate. For more details, refer to section 7.4.1.

Electrical Black Windows

With the YWIN_BLACK register, windows can be made 'electrical black' (setting a fixed

voltage at the read out path instead of the pixel voltage). If the respective bit of the

YWIN_BLACK register is set high (same mapping as YWIN_ENA), then all signal information

in the window is suppressed. This results in a black window containing only readout FPN

information. This feature could be used for column FPN correction.

Window Overlap

Several vertical windows may overlap, although this is only useful in subsampling mode. If the

same row is read multiple times within one frame, it will only contain valid data the first time

(destructive read out).
