The imaging array can be readout with different modes as described here below:
Dark calibration
The VS6502 has an automatic dark calibration system which is used to set the black level of the
output video data to 16. The VS6502 has special ‘dark’ pixel rows which have the same exposure
setting as the visible lines but are shielded from incident light. The VS6502 uses these lines to
calculate an offset which is then be applied to the video data AND to the dark lines themselves. In
this case the mean value of the dark lines output will be 16.
The measured dark line offsets are reported in registers [9] and [10]. By default these offsets are
applied to the video data but a user may choose to apply no offset at all or their own offset which
may be entered in registers [44] and [45] in 2’s complement format.
The dark calibration function is controlled via register [46].
Shuffle horizontal readout, bit [7] of serial register [17]. Even columns (2,4,6.) are readout first.
Mirror horizontal readout, bit [3] of serial register [22]. Columns are readout in reverse order.
Mirror vertical readout, enabled by setting [4] of serial register [22]. Rows are readout in
reverse order.
