(0x2A = 0b101010. This value is not recommended since bit #3 is set to

1 here,

even though it is not used by the parameter.)

Exposure timing mode (bit group e)

The exposure timing mode allows to switch between the continuous mode and
three different IOD modes.

Continuous mode

Bit group: e

Value: 0

The camera outputs images as fast as possible in free-running mode.

The gap between two images is only one line, the total frame duration takes
t

FDmin

. The exposure time is nearly equal to this inherent minimal frame dura-

tion.

Image on demand mode (IOD)

Bit group: e

Value: 1

The exposure is triggered by an external signal.

Use parameter

T to select the signal source. A rising edge starts exposure syn-

chronizing to the line after the next line.
