6.8.7 Asynchronous exposure, shutter control by timer

This operating mode is selected with register 6:

:r6[7..4] = 0xf

The asynchronous exposure time is dependent on :r2[9..0]. The exposure timer counts as many lines as

are defined in register :r2[9..0].

Exposure time:

= 1/F

sens

* 136 • (1+r2[9..0]) [Sec]

... exposure time

sens

.. sensor clock

example: sensor clock = 66MHz

value of r2[9..0] = 6

= 136 • 6

• 15 ns = 12,2 µs
