Row Start
The first row to be read out (not counting any dark rows
that may be read). To move the image window, set this
register to the starting “Y” value. Setting a value less than
eight is not recommended, as the dark rows should be read
using Reg0x22.

Column Start
The first column to be read out (not counting dark columns
that may be read). To move the image window, set this
register to the starting “X” value. Setting a value below
Reg0x18 is not recommended, as readout of dark columns
should be controlled by Reg0x22.

the beginning of a row. See “Minimum Horizontal

Blanking B
Number of blank rows in a frame when context B is selected

Reg0x22[2:0]). The actual vertical blanking time can be
controlled by the shutter width (Reg0x9). See “Output Data
Timing (Default Mode)” on page 11.
